1. Introduction
1.1 Video Recorder Overview
The Video Recorder (Figure 1-1) is part of the family of multi-point, multi-function video products. The
instrument offers display versatility, flexible data storage, up to 8 control loops, each one can run its own
profile, and advanced math functions. This integration of several functions eliminates the need for
multiple devices and reduces installation costs.
The instrument features a high resolution LCD display which is capable of displaying up to 16 different
colors simultaneously. The front door opens to allow access to a 100MB ZIP disk drive. A mini DIN
connector can be used on the front door for connecting a PC keyboard or barcode reader for easy
labeling of parameters. Barcode reader also stores Event Records to disk.
Sixteen panel keys control all functions of the instrument, including configuration.
The instrument will accept thermocouple, RTD, pyrometer, milliamp, millivolt and volt inputs. Up to eight
analog outputs are available for retransmission or control. Data can be directed to various display
formats, stored on floppy disk, or read from an optional serial communications link. Analog and discrete
data can be displayed in trend or tabular format. Viewed data can be either “live” (real time inputs) or
historical (retrieved from disk).
Flexible modular design and several options make this instrument adaptable to nearly any industrial
application.

2.4 Wiring the video recorder
2.4.1 Recommendations
CAUTION
All wiring must be in accordance with local electrical codes and should be carried out by authorized and
experienced personnel.
The ground terminal must be connected before any other wiring (and disconnected last).
A switch in the main supply is mandatory near the equipment.
If an external fuse is used to protect the electrical circuit to the video recorder, the fuse should match the
video recorder fuse rating (fuse type) as well as for the fuseholder.
Sensor wiring should be run as far as possible from power wiring. (motors, contactors, alarms, etc.)
To reduce stray pick-up, we recommend the use of a twisted pair sensor wiring.
EMI effects can be further reduced by the use of shielded cable sensor wiring. The shield must be
connected to the ground terminal.
Failure to comply with these instructions may result in product damage.

2.5.7.5 Rear connection
The video recorder has built in circuits to reduce the effects of most electrical noise. We recommend
that you review the following guidelines, to minimize the noise effects.
1. Separate the communication leadwires from the line voltage, the alarm output, contactors, motors etc...
2. For a communication distance, over 1.5 meters, use a separate metal tray, or metal conduit.
3. Use wiring cable composed of twisted pair wirings, with a shield for RS485 and RS422. Use a shielded
cable for RS232.
4. Connect the shield wire to the ground, at one end only, preferably at the video recorder. Use for example
a wiring cable type: Belden 9271 twinax, or equivalent.
5. We recommend to install a 120 ohms resistor between TXA and TXB, on the last video recorder on
communication link.
6. The maximum capabilities are:

Section 4 How To Program Function Blocks and Features
3.3 Modes of Operation
The instrument has three modes of operation: Program, Online, and Maintenance. Each mode has its
own menus. Most menu items provide access to sub-level menus. The SET MODE item switches the
instrument from one mode to another. Your instrument may have reduced menus if options are not
present.
Program mode
Program Mode is an off-line mode for programming (configuring) the instrument. In this mode, all inputs
and outputs are frozen. If any of the five relays are assigned as DAT outputs the recorder will stop
pulsing them when it is placed into Program Mode. The outputs will remain frozen in their present state,
either On or Off.
Online Mode
Online Mode enables full use of the instrument with its inputs, outputs and internal programming. In this
mode, it is fully interactive with all externally connected elements.
Maintenance Mode
Maintenance Mode is an off-line mode for maintaining proper and complete functioning of the instrument.
Functions include calibration, off-line diagnostic testing, and various setups for operation. In
Maintenance Mode, all inputs and outputs are frozen. If any of the five relays are assigned as DAT
outputs the recorder will stop pulsing them when it is placed into Maintenance Mode. The outputs will
remain frozen in their present state, either On or Off.

Once you have established which MAIN MENU you are on, use the Up Arrow and Down Arrow buttons
to verify each MAIN MENU choice as indicated in Figure 3-2.
Use the Up Arrow and Down Arrow buttons to find and highlight the menu’s SET MODE prompt.
When the SET MODE prompt is highlighted, press the Enter button.
Use the Up Arrow or Down Arrow buttons to switch the instrument to one of the other two instrument
modes and press the Enter button.

Once within the mode selected in Step 5, scroll through the mode’s MAIN MENU using the Up Arrow and
Down Arrow buttons. Verify each menu choice as indicated in Figure 3-2.
Repeat Steps 3 through 6 for the last of the three mode selections possible.
Having completed the preceding exercise, changing the instrument’s mode should now be a simple task.
Furthermore, a fundamental understanding of how the Menu, Up Arrow, Down Arrow, and Enter buttons
work should now be at your fingertips.
Now use the Menu, Up Arrow, Down Arrow, and Enter buttons to verify the ON LINE, PROGRAM, and
MAINTENANCE mode sub-level menus detailed in Figure 3-3, Figure 3-4 and Figure 3-5. The sub-level
menus shown represent only the first sub-level below each mode’s MAIN MENU. There are several sub-
level menus, not indicated here, that run further below each first sub-level. Note that once inside of a
sub-level menu, regardless of how “deep” the level is, a press of the Menu button will return you to the
next highest menu level. In case you get lost within a mode’s sub-level menu, keep pressing the Menu
button until the ON LINE, PROGRAM, or MAINTENANCE mode MAIN MENU appears on screen.
Be advised that Figure 3-2 through Figure 3-5 comprise a basic “road map” for navigating the menus
within the programmer’s three modes. Sections 4 through 8 of this manual will provide detailed
descriptions of each menu choice and complete guides through all the sub-level menus that run below
the levels indicated in these Figures.

3.9 Definition of Function Blocks
Definition
A function block is a unit of software that performs a set of operations on its input parameters and
function block parameters and produces output parameters. These output parameters can be
programmed as inputs to other function blocks, whose output parameters can be programmed as inputs
to other function blocks, and so on. By programming all desired function blocks' input parameters and
function block parameters, you configure the instrument to measure and control your process.
Types of function blocks
Each function block performs a set of operations which fulfills a unique purpose. For example, the
Analog Input function blocks processes the analog input data, the alarm function block processes
alarms, and so on.
Table 3-3 describes each function block.
Some function blocks—namely, Analog Input, Analog Output, Discrete Input, and Discrete Output—
interface with the hardware; that is, they are the link between the instrument and the input or output
hardware. The Analog Input and Discrete Input function blocks convert the incoming process data (like
the process variable or any discrete on/off signals from a switch) into information usable by the
instrument. This incoming information is processed according to the entire function block configuration in
the instrument, and it is ultimately passed on to the output function blocks. The Analog Output and
Discrete Output function blocks convert this output information into a voltage or current which is fed to
the corresponding output hardware (like a current output or relay).
Other function blocks are not directly “seen” by the hardware; they are purely software. They can be
thought of as the middle of the process described in the previous paragraph. For example, a Standard
Splitter Calculated Value can split a control loop’s output into 2 values: one for heating and one for
cooling. These 2 values can be passed on to the Analog Output function block which ultimately controls
the amount of output current or voltage.
Flow of information
The “flow” of information— from the input hardware to the input function blocks to the function block
configuration to the output function blocks to the output hardware—can be likened to a river flowing from
upstream to downstream. In some cases, like with a control loop’s feedback, this analogy is not true
because the information is flowing in a circle, but it is a helpful way to view how function blocks are
generally interconnected. For example, the Analog Input function block is typically upstream of the
Control Loop function, which is typically upstream of the Analog Output function block. Of course, if two
function blocks are not directly or indirectly connected, there is no flow between the two. Just remember
that every function block has input, does a set of operations, and produces an output. When several
function blocks are linked together, there is a flow of information.

Purpose
Alarm AL 96 Causes alarms under specified conditions.
Analog Input AI 48 Interfaces with measuring input hardware (thermocouple,

Constant CN 32 Outputs a number or an analog parameter value.
Discrete Input DI 36 Interfaces with discrete input hardware (dry contact

Discrete Output DO 36 Interfaces with output relay hardware (AC relay, DC
relay, mechanical relay, open collector output).
Loop LP 8 PID or ON/OFF control with various outputs.
Setpoint Profiler SP 4 Generates a time-varying setpoint for a loop’s Setpoint
#2.
System SY 1 Outputs discrete status of alarms, data storage, and
diagnostics; outputs analog value of reference junction
temperature. This function block is not programmable; its
outputs are produced automatically.
Totalizer TL 48 Outputs accumulated total over time.
* Depends on options ordered.
Why use function blocks?
Function blocks give you configuration flexibility. For instance, the instrument does not have a dedicated
relay that is activated during an alarm; instead, you can program any of several Alarm function blocks to
control any relay. Also, there is not a specific input for your process variable; any of several Analog Input
function blocks can be programmed to be your process variable. In general, function blocks let you
connect the output parameter of any function block to the input parameter of any function block.

Input parameter
A function block's input parameter can be configured to be OFF, a number, or it can receive its data from
outside the block from another block's output codes. These output codes are shown in
Table 3-4. That is, an input parameter is any menu item that can be programmed as (connected to) one
of these output codes. These output codes are grouped under the menu choice PARM. When you are
programming a function block and one of your choices is PARM, you know you are programming an
input parameter. See Figure 3-7.
For example, suppose you are programming an alarm function block. One of the alarm’s menu items is
INPUT, which specifies which point will be monitored for an alarm condition. One of the choices for the
INPUT is PARM, which lets you connect the INPUT to one of the output codes in Table 3-4. Therefore,
the INPUT is an input parameter because it receives its data from another function block.
Some function blocks can have multiple input parameters. For example, an Alarm function block has an
INPUT and a SETPOINT, both of which can be connected to other function blocks.
Discrete Input function blocks have no input parameters; that is, they have no inputs that can be
connected to another block’s output codes.
Programming and Operating Concepts
Video Recorder – User Manual 52
Function block parameter
A function block parameter’s data is contained within the block. When you are programming a function
block and are not given a choice of PARM, you are programming a function block parameter. Typical
choices when programming a function block parameter are NONE, OFF, any numerical value, or a list of
options for the parameter, but not PARM. See Figure 3-7.
For example, to program an Alarm function block’s ALARM ACTION, you select from a list of choices:
NONE, LOW, HIGH, DEV, LRATE, HRATE.
Other function block parameters are an Analog Input’s RANGE LOW and RANGE HIGH, where you
specify the voltage range or temperature range.
Output code
An output code is the result of the function block's operations on the input parameters and function block
parameters. It is designated by one of the two-character output codes shown in Table 3-4. An output
code can be programmed to be the input to one or several other function blocks. See Figure 3-7.
Output codes are either discrete (can be on or off) or analog (numerical value). For example, DI1 OS is
the output status of Discrete Input #1: on or off. AI1 OV is the output value of Analog Input #1: a voltage
or temperature. Therefore, a discrete input parameter must be programmed with only a discrete output
code, and an analog input parameter must be programmed with only an analog output code.
ATTENTION
The function block SYSTEM PARAMETER, abbreviated SY, does not have input parameters or function block
parameters like the other function blocks; SY produces output codes only. These output codes, shown in Table
3-4, are mostly values or states that indicate the status of system-wide parameters. For example, if any Alarm
function block’s output status is ON, the SY function block’s AG (alarm global) output code is also ON.
Another example is the SY F1 output code, which produces a quick ON-to-OFF discrete signal when the F1
key is pressed. This SY F1 can be used as a trigger to another action. For example, to allow an operator to
start the Profile or reset the Totalizer by pressing the F1 key, you can program a Setpoint Profile’s Start
parameter or a Totalizer’s Reset parameter with SY F1.

3.11 How to program input parameters
A function block has two types of programmable parameters: input parameters and function block
parameters. When in a function block’s Program menu, if a menu item has choices OFF, a number, or
PARM, then the menu item is an input parameter to that function block. That is, if you choose PARM
you can connect the input parameter to another function block’s output code.
How to connect an input parameter to another function block
One way to program an input parameter is to connect it to an output parameter from another function
block. We will show you this procedure using a specific function block’s input parameter, but the
keystrokes used in the procedure will apply when you are making any input parameter connection.

Assume we want to make the connections shown in Figure 3-8. We want Analog Output#1, a current
output, to get its input from Control Loop#2’s output value. Therefore, we must program Analog
Output#1’s Input Source parameter with the output code that represents Control Loop#2’s output value.
The following procedure shows how.
Table 3-5 Output Code Connection Procedure
Step Action
1 In the Program Analog Output menu, select ANALOG OUTPUT#1.
2 Consult the Program Analog Output section of this manual to learn about the menu item you wish to
change, namely, INPUT SOURCE.
3 Press Down Arrow button to move the cursor to the menu choice INPUT SOURCE.
4 Press Enter to move the cursor to the right side of the display where the choices for INPUT SOURCE
are.
5 Press Up Arrow until PARM is displayed. If you press too many times and a number is displayed,
continue pressing Up Arrow until PARM is displayed again. If you press Down Arrow while the
number is displayed, the instrument assumes you want to enter a number, not a parameter. If you
pressed Down Arrow, you must press Menu, then press Enter, then Up Arrow until PARM is
displayed.
6 Press Enter to select PARM, which gives you choices for output codes to connect to. Figure 3-9
shows the format for all output codes.
7 Press Up Arrow or Down Arrow until LP is displayed. From Table 3-4, we know LP is the designator
for the Control Loop function block type.
8 Press Enter to select LP.
9 Press Up Arrow or Down Arrow until 2, the Control Loop number we want, is displayed.
10 Press Enter to select 2.
11 Press Up Arrow or Down Arrow until OV is displayed. From Table 3-4 we know OV is the output
code for the Control Loop’s output value.
12 Press Enter to select OV. The cursor moves to the left and the connection from LP2 OV to Analog
Output#1’s INPUT SOURCE has been made.

Figure 3-9 Function Block Connection Format
Before programming a function block’s input parameter with a CV’s (Calculated Value) output code, you
must program the CV first. Otherwise, the CV’s output parameter will not be available for programming.
The function block SY (System Parameter) operates internally and cannot be programmed. It
automatically produces outputs which reflect the status of alarms, data storage, diagnostics, and
reference junction temperature. These outputs can be used as inputs to function blocks.
How to program an input parameter with a number
Besides connecting an input parameter to another function block, you can program an input parameter
with a number. The instrument will accept -999,999 to 9,999,999.
Continuing with the previous example, assume we want Loop #2’s Setpoint #2 to be a number.
Therefore, we must program Loop #2’s Setpoint #2 parameter with a number, say 95. The following
procedure shows how.

Table 3-6 Example Number Selection Procedure Using Front Panel Buttons
Step Action
1 In the Program Control Loops menu, select LOOP #2.
2 Consult the Program Control Loops section of this manual to learn about the menu item you wish to

3 Press Down Arrow button to move the cursor to the menu choice SETPOINT #2.
4 Press Enter to move the cursor to the right side of the display where the choices for SETPOINT #2
are.
5 Press Up Arrow until NUMBER is displayed. Press Enter.
6 The rightmost digit will slowly flash on and off, indicating the cursor position.
Since we want to change the number to 95.00, press the Left Arrow until the ones digit flashes. The
Left Arrow moves the cursor to the left.
7 Press Up Arrow to change the 0 to a 5.
8 To change the tens digit, press Left Arrow to move the cursor one place to the left.
9 To change the 0 to a 9, press Up Arrow nine times.
10 At this point, 95.00 should be displayed with the 9 flashing. Since 95.00 is the value we want, press
Enter to select it. The cursor moves left to the SETPOINT #2 prompt and the value is selected.
ATTENTION
To enter a number with a connected keyboard, instead of steps 5-10 simply type in the number 95 and press
Enter.
How to program a discrete input parameter with a number
Table 3-6 shows how to connect Setpoint #2, an analog parameter, to a number. You can also connect a
discrete parameter to a number. A discrete parameter, such as an alarm’s input source, can be
connected to any discrete parameter type in Table 3-7, or it can be programmed with a 0 to signify the off
state or with a 1 to signify the on state. Enter a value of 1 or 0. For example, if you program an alarm’s
input source (Figure 3-7) with a value of 1, the alarm’s output (AL1 OS) will always be on.
To program a discrete parameter with a 1 or 0, perform the following procedure. The procedure uses
Alarm1’s Input source as the parameter being programmed.
Table 3-7 Example Programming Discrete Input Parameter with a Number
Step Action
1 In the Program Alarms menu, select ALARM #1.
2 Consult the Program Alarm section of this manual to learn about the menu item you wish to change,
namely, INPUT SOURCE.
3 Press Down Arrow to move the cursor to INPUT SOURCE.
4 Press ENTER to move the cursor to the right side of the display where the choices for INPUT
SOURCE are.
5 Press Up Arrow until 1 or 0 is displayed.
6 Press ENTER to select. The cursor moves to the left and the display indicates your choice of 1 or 0
has been made.
Programming and Operating Concepts
Video Recorder – User Manual 58
ATTENTION
Note the difference between programming a discrete parameter with OFF and programming it with a 0. “OFF”
means “not connected”; 0 means “off state”.
3.12 How to program function block parameters
The second type of programmable parameter is a function block parameter. A function block
parameter’s data is contained within a function block and cannot be connected to another function block.
When you are programming a function block and are not given a choice of PARM, you are programming
a function block parameter. Typical choices when programming a function block parameter are NONE,
OFF, any numerical value, or a list of options—but not PARM.
Programming procedure
Here is the procedure for programming a function block parameter. It is an example using a specific
function block parameter, but the keystrokes used will apply when you are programming any function
block parameter.
Continuing with the example from Figure 3-8, assume we want Analog Output#1 to default to its lowest
value if the input source, LP2 OV, fails. Therefore, we must program Analog Output#1’s failsafe
parameter with the appropriate selection. The following procedure shows how.
Table 3-8 Example Function Block Parameter Selection Procedure
Step Action
1 In the Program Analog Output menu, select ANALOG OUTPUT#1.
2 Consult the Program Analog Output section of this manual to learn about the menu item you wish to
change, namely, FAILSAFE.
3 Press the Down Arrow button to move the cursor down to FAILSAFE.
4 Press Enter to move the cursor to the right side of the display where the choices for FAILSAFE are.
5 Press Up Arrow or Down Arrow until DOWN is displayed.
6 Press Enter to select DOWN. The cursor moves to the left and DOWN is selected.

3.14 How to program common configurations
Being able to diagram a control configuration in terms of function blocks makes it easier to program and
configure your instrument for its intended process control application. This function block diagram you
create can be used as a “construction blue print” to program the instrument. Each block in the diagram
relates to a dedicated instrument programming menu in the instrument’s PROGRAM mode.
What follows are examples where common control configurations are presented along with their function
block diagrams. The first example is a simple control arrangement in great detail to help you understand
function block diagram basics, followed by more sophisticated examples. Once you understand how to
diagram function blocks, you will be able to draw a diagram for virtually any control strategy regardless of
complexity. Understanding the relationship between such diagrams and the instrument’s programming
menus is key to successfully mastering the instrument’s many capabilities and features.

An example of one of the most common and simple control strategies is in Figure 3-11 below.

Programming and Operating Concepts
Video Recorder – User Manual 61
1. Diagram the function blocks
To configure this application using the instrument, your task is to build up a simple current control loop.
Note that this control loop must monitor and control the temperature of the furnace zone to a local set
point of 500 ºF. Using a 4 to 20 mA signal applied to a gas valve actuator, the furnace zone’s
temperature will be controlled by regulating the flow of gas to the zone’s burner.
The instrument will measure temperature, in a range between 0 and 1000 ºF, by means of a Type J
thermocouple.
To support this application, a 4 to 20 mA control loop with a thermocouple process variable must be
configured. Three function blocks—one for specifying a thermocouple analog input, a second for a
standard PID control loop, and a third defining a 4 to 20 mA analog output—are needed to produce this
control strategy’s function block diagram.
Each function block should first be arranged as in Figure 3-12. Analog input and output function blocks
are represented by right-pointed triangles. Control loop function blocks are represented by right-pointed
parallelograms.

2. Label input parameters
Properly label each function block. First, assign to each function block a name that identifies it within the
hardware and feature capacities of the instrument being worked with. You may assign any of the analog
inputs, control loops, and analog outputs that your instrument has to the blocks comprising the function
block diagram drawn. For simplicity, AI1, LP1, and AO1 will be used in this example.
Refer to Figure 3-13. Note that AI5, LP2, and AO2 could just as easily have been used.
Programming and Operating Concepts
Video Recorder – User Manual 62
3. Label output parameters
The second part in labeling each function block is to denote the blocks’ major input and output
parameters. Each of these parameters will correspond to actual menu settings that you program on the
instrument. As shown in Figure 3-13, the AI1 function block’s input parameter will be the actual Type J
thermocouple run from the furnace to the instrument’s AI1 input terminals. The AI1 block will process the
thermocouple’s millivolt signal to generate a temperature measurement. AI1’s output value, denoted
“AI1 OV”, will essentially be the furnace zone temperature. The LP1 function block is shown, for now,
with one input denoted by “PV”. Here, the control loop block will expect to find the data comprising its
process variable. The LP1 block’s single output is the loop’s main control output. Denoted “LP1 OV
(Loop 1’s Output Value)”, it will range between 0 and 100%. The value of LP1 OV at any given instant
will be determined by the control loop function block’s PID algorithm.
The last block in the diagram is the analog output function block, AO1. Drawn at this point with just a
single input and output, its primary purpose will be to generate a 4 to 20 mA signal that linearly
corresponds to whatever value is applied at its input. For example, if AO1’s input is defined as some
value that ranges from 0 to 100%, an input value of 0% will cause AO1 to generate a 4 mA signal at the
instrument’s AO1 output terminals. A 12 mA signal will be generated in response to an input of 50%,
while 20 mA will result when a 100% input value is applied. AO1’s input parameter is denoted “IN”, with
its output parameter labeled to identify it as the physical 4 to 20 mA signal detectable at the pair of
instrument rear terminals dedicated to AO1.

4. Label function block parameters
Finally, label each block’s internal parameters. “Internal parameters” may also be referred to as “function
block parameters.” As in the case of input and output parameters, internal parameters associated with
each block correspond to actual menu settings you program in the instrument. While input and output
parameters constitute either data exchanged between function blocks or physical signals exchanged
between the instrument and the outside world, internal parameters are settings that uniquely define the
operation of the function block they are associated with. Use of a function block’s internal parameters is
for the most part limited to within the operations of the function block itself.
It is not always possible, or even practical, to draw every internal parameter that a function block has or
might need. Therefore, as a rule-of-thumb for starting out, you should first think of internal parameters
as simple labels that further define and clarify the internal operation of the function block. With this rule-
of-thumb in mind, internal parameters become items that are hopefully intuitively obvious. At this point,
what may or may not be an “intuitively obvious” internal parameter will depend on your level of process
control expertise. For the function block diagram built up so far, internal parameters that can be
presumed from the control strategy of Figure 3-11 are indicated in Figure 3-14. Here, the AI1 function
block has been labeled to show that its “INPUT TYPE” will be a Type J thermocouple with a
measurement range between 0 (RANGE LOW) and 1000 ºF (RANGE HIGH).
The label “STANDARD” has been used to indicate the type of control loop LP1 will be, along with the
notation “SP = 500” to show that the loop’s set point will be 500 ºF. The loop tuning constants of GAIN,
RESET, and RATE have been initially indicated as 10, 1 repeat/minute, and 0 minutes, respectively. As
far as the AO1 function block is concerned, its input range has been defined between 0 (IN LOW LIMIT)
and 100 (IN HIGH LIMIT) in anticipation of using LP1’s output to drive the 4 to 20 mA signal it will
generate. Note how AO1’s output range has been defined through use of the notation “OUT LOW LIMIT
= 4” and “OUT HIGH LIMIT = 20.”

Figure 3-14 Labels For Internal Function Block Parameters
Note that the internal parameters that we have specified in the function block diagram built up so far are
based largely on what can be inferred from the elements of the control configuration depicted in
Figure 3-11. These internal parameters will relate directly to settings found in instrument programming
menus that exist for each particular function block. As your experience and familiarity with programming
the instrument increases, you will become more familiar with some of the less intuitive parameters and
you will include these in your diagrams.
5. Connect the blocks
The next step is to connect the function blocks in the diagram. Refer to Figure 3-15.
The interconnection lines drawn depict the flow of information between function blocks and represent
how the blocks work together to support the complete control strategy. As shown, the furnace zone
temperature measurement that AI1 generates will essentially be used as the process variable of the LP1
control loop. Based on the values of the loop’s tuning constants and on how far AI1 OV deviates from
the 500 ºF set point, the control loop function block’s PID algorithm will accordingly adjust LP1 OV to
whatever value will be necessary to maintain the process’ set point. LP1 OV, which ranges from 0 to
100 %, will in turn be applied to AO1’s input to drive the 4 to 20 mA control signal applied to the valve
actuator. By modulating the valve actuator’s position, this 4 to 20 mA signal will regulate the gas flow to
the furnace zone burner and thereby allow the instrument to control the heat levels measured in the
zone.

6. Draw the Feedback connection
To fully complete the function block diagram, one final and very important interconnection must be
drawn. In setting up control loops in this instrument, a feedback path must be specified between the loop
function block itself and the hardware element that externalizes the loop’s output to the real world. That
is, the control loop block needs confirmation from the analog output block connected to it that the percent
output levels it calls for have been correctly translated into accurate output signals. The feedback path
that provides LP1 with this confirmation is established by means of program settings depicted in
Figure 3-16.

Here, the function block diagram is drawn to include the key components of a typical loop feedback path.
The AO1 function block has been changed to feature a second output denoted “AO1 BC.” This output
has been connected to a feedback input at LP1 identified by the notation “FB.” The “AO1 BC” designator
stands for “Analog Output 1’s Back Calculation.” When the control loop is brought on-line, AO1 BC will
essentially represent the value of AO1’s 4 to 20 mA output at any particular instant. The term “Back
Calculation” is used to reinforce the idea that this information is being sent “upstream” against the flow of
all other information within the function block diagram.

This application requires a basic time proportioning control loop to monitor and control the pH of the
wastewater to a local set point of 7 pH units. That is, the loop will “neutralize” the wastewater so that it
can be safely released to the environment. The wastewater pH, which is assumed to be primarily acidic,
will be controlled by introducing a caustic reagent to the contents of the treatment vessel. This will be
done through use of a time proportioning relay signal that will pulse a pump connected to a caustic
reagent source.

This drawing is similar to the temperature control application. The analog input, control loop, and analog
output function blocks (AI1, LP1, and AO1) have been used similarly. The discrete output function block
was added, drawn as a circle at AO1’s apex and named “DO1.” Recall that any analog input, control
loop, analog output, or discrete output available may be used. Up to 36 discrete outputs (DO1 through
DO36) are potentially available depending on the instrument’s model number.
Programming and Operating Concepts
Video Recorder – User Manual 66
From Figure 3-18, the instrument’s AI1 function block will essentially process the 4 to 20 mA transmitter
signal to generate a pH measurement. This measurement will be “AI1 OV” which, in turn, will be applied
to LP1’s process variable input, “PV.” Before the 4 to 20 mA signal is applied to AI1, it will be converted
to a 1 to 5 VDC signal with a 250 shunt resistor. AI1 will be configured to generate a pH measurement
in a range from 0 (RANGE LOW = 0) to 14 (RANGE HIGH = 14) in response to a voltage input between
1 (CKT LOW = 1) and 5 (CKT HIGH = 5) VDC. The PID algorithm of the control loop function block will
adjust the value assumed by LP1 OV between 0 and 100%. This 0 to 100% signal will be applied to
AO1, which will be configured as a DAT type analog output. The internal parameter of “IMPULSE TIME”
in AO1 is the DAT analog output’s cycle time or period. With a specified impulse time of 150 seconds
(an arbitrarily picked value), the DAT output will be ON for 75 seconds and OFF for 75 seconds when the
input from LP1 is set to 50%. The ON and OFF times will be determined completely by the % output
levels called for by LP1. Finally, to externalize the ON and OFF output states of AO1 to the outside
world, the DO1 output relay, represented by the DO1 function block, will be programmed for AO1’s
exclusive use. Hence, as AO1 switches between ON and OFF states in response to LP1 OV’s % output
levels, so too will the DO1 output relay to generate the pulses required to drive the caustic reagent
pump.
Split Output or Duplex Control
Split output or duplex control loops are typically used in heat/cool applications. Temperature is
controlled through simultaneous use of both heating and cooling elements. If the instrument was to
support a heat/cool control configuration, an example of the control scheme that might be dealt with is
illustrated in Figure 3-19.

The instrument must be set up to produce two 4 to 20 mA control signals. By applying them to current-
controlled valve actuators coupled to hot and cold water valves, these signals will regulate the amount of
hot and cold water introduced to the vessel to maintain the water temperature at whatever set point will
be programmed. The temperature of the water will be measured by means of a three-wire 100
Platinum RTD. This process may be likened to manipulating hot and cold faucets regulate water
temperature.
Programming and Operating Concepts
Video Recorder – User Manual 67
In Figure 3-20, the analog input function block AI1 is depicted processing the resistance values produced
by the RTD. The resulting water temperature measurements (AI1 OV) are then fed to the process
variable input (PV) of the LP1 control loop block. Note how LP1 has been defined as a split output
control loop using the notation “TYPE = SPLIT.” Unique to this control loop is the defined range of its
output value, LP1 OV. Where the standard control loops mentioned thus far have had outputs ranging
exclusively between 0 and 100%, the % values of the split output control loop vary between -100 and
100. 0% is considered the midpoint for this control loop’s output range. When brought on-line, a 0 to
100% output value will be generated by LP1 when hot water is needed to maintain the temperature at set
point. When the addition of cold water is necessary, the loop’s output will assume a value between 0
and -100%. Note that to externalize the control signals generated by LP1, two analog output blocks,
AO1 and AO2, will be used. AO1’s 4 to 20 mA signal will be tied to the hot water valve actuator, while
the actuator that adjusts the position of the cold water valve will receive its mA control signal from AO2.
To provide AO1 and AO2 with usable input driving signals, LP1’s output will be applied to a function
called a “standard splitter (STD SPLITTER).” Made from one of the instrument’s calculated value
function blocks (“CV’s”), the standard splitter will essentially be a mechanism that translates the %
values of the split output control loop into two distinct 0 to 100% signals. They will be applied to the
inputs of AO1 and AO2 and, as such, will drive and linearly correspond with AO1 and AO2’s 4 to 20 mA
outputs.

The two outputs on CV1 that will drive AO1 and AO2 are respectively labeled “CV1 A1” and “CV1 A2.”
CV1’s basic operation is described by a plot of these outputs versus LP1 OV. Shown in the lower left of
Figure 3-20, the plot demonstrates that CV1 will produce a 0 to 100% value at its CV1 A1 output when
LP1 calls for an output level between 0 and 100%. CV1 A2 will remain at 0%. When applied to AO1, the
CV1 A1 value will activate the 4 to 20 mA signal needed at the hot water valve actuator to make the
water temperature in the vessel rise. Similarly, when LP1 calls for an output level between 0 and -100%,
CV1 will produce a corresponding 0 to 100% value at CV1 A2. This time, CV1 A1 will remain at 0% and
the CV1 A2 value generated will induce the introduction of cold water into the vessel to cool its contents
down.
Note the function block diagram’s use of three back calculated feedback paths. Two such paths are
labeled AO1 BC and AO2 BC. They are connected to CV1 from the analog output function blocks at
inputs denoted “FB1” and “FB2.” CV1 BC, the third feedback path, runs from CV1 to the FB input of
LP1. All three feedback paths work together to acknowledge to LP1 that the appropriate output signals
have been generated in response to the % output levels the loop has called for.

Cascade Control
An example of a cascade control application is featured in Figure 3-21. Cascade control is typically used
when two process values must be simultaneously controlled, with one process value directly influencing
the behavior of the other. In this control strategy, each process value is supported by its own dedicated
control loop. The term “cascade” is used because it describes how this control approach literally
attaches both control loops together. This act of linking control loops allows for the regulation of both
process values using one and only one % output control signal.

Figure 3-21 Temperature Control Of An Oil Heated Chemical Reaction Chamber
InFigure 3-21, the temperature in a chemical reaction chamber is determined by the temperature of the
heated oil surrounding it. Heating the oil is done by an electric heating element driven by a 4 to 20 mA
controlled SCR and external power source. In this application the instrument controls the temperature of
the chemical reaction chamber through control of the heat emitted by the jacket tank oil. The instrument
must provide a single 4 to 20 mA control output to govern the voltage switched by the SCR and, hence,
the heat applied to the entire system. Temperature is monitored with thermocouples.
The function block diagram of the required instrument configuration is featured in Figure 3-22
Note that this diagram illustrates the classic cascade arrangement of two control loops that defines the
cascade control strategy. The first control loop, LP1, is designated as the primary cascade loop by the
notation “CAS_P.” The notation “CAS_S” indicates LP2’s designation as the secondary cascade loop.
Note how both control loops are joined together. In addition to the back-calculated feedback path set up
between the two (LP2 BC), LP1’s output is connected to an input on LP2 that at this time must be
introduced. Denoted as SP2, this input is LP2’s remote set point input.

Figure 3-22 Function Block Diagram Of The Cascade Control Strategy
Recall that based on the instrument’s model number, up to eight control loops (LP1 through LP8) are
potentially available for use within the instrument. All control loops in this product may be programmed
to operate using up to two user defined set point parameters, designated by SP1 and SP2. Should you
implement a control loop using one or both setpoints? That depends on what is necessary to meet the
requirements of the specific application being dealt with. When in the on line mode and viewing a control
loop’s dedicated on line display, the working set point of the live control loop can be switched between
SP1 or SP2 by simply pushing the “SP” key on the instrument’s front door. Note that while both set point
parameters may be programmed to have straight numeric values, only SP2 may be defined as a remote
set point. That is, SP2 may be set up so that its value is determined by the output value of another
function block, such as a setpoint profile. In the cascade control strategy demonstrated in Figure 3-22,
SP2’s remote set point functionality is exploited by the LP2 secondary cascade loop. When this control
configuration is made operational, LP2’s working set point, SP2, will have a value determined by LP1
OV.
In Figure 3-22, the process values of each loop are the output values of the AI1 and AI2 analog input
function blocks. AI1 will produce temperature measurements of the reaction chamber and provide them
to the process variable input of LP1, while measurements of the oil temperature in the jacket tank will be
furnished to LP2’s PV input by AI2. Because LP1 OV will provide LP2 with its operating set point, LP1’s
output range will be defined in engineering units of temperature instead of the usual 0 to 100%. LP2’s
output range is 0 to 100%, in anticipation of using it to drive the AO1 function block’s 4 to 20 mA signal.
Note that the range covered by LP1 OV will have to be consistent with the operating temperature range
of the oil. For example, if it is determined that the oil temperature will be manipulated between 75 and
500 ºF, the low and high limits assumed by LP1 OV (and, for that matter, SP2) will equal 75 and 500,
respectively. Finally, LP2 BC and AO1 BC are the two back-calculated feedback paths shown. As is
true for the operation of all back-calculated feedback paths, both LP2 BC and AO1 BC work together to
acknowledge the cascaded control loops that the appropriate actions have taken place in response to
both loops’ output values.
The method used to coordinate the tuning of the cascaded loops is particularly interesting. Using the
diagram of Figure 3-22, the first priority is to tune the secondary cascade loop of LP2. With LP1 kept in
manual mode, tuning may begin by first placing LP2 in manual mode and then manipulating LP1’s
output. This will allow the generation of an LP2 set point that will induce a process upset when the
secondary loop is placed back in automatic mode. Only after LP2 has been tuned can LP1 be tuned.
When tuning LP1, LP2 will be kept in automatic mode throughout the entire time LP1 is exercised. Since
the tuning of LP2 will have already been established, tuning LP1 may be approached by first mentally
“blocking out” the secondary control loop’s existence and visualizing LP1’s output as connected to a sort
of virtual analog output function block. In this light, tuning the overall cascade control configuration
becomes the considerably simpler matter of tuning a single control loop.

Set Point Profile Implementation
By definition, set point profiles are essentially user specified plots of process values against time. These
plots are characterized by “segments” which are a series of intervals of varying time lengths that divide
the plots into several segments. Within each segment, process values are typically drawn as straight
lines that ramp up or down or stay constant at predetermined levels. An example of a simple five-
segment set point profile is shown in Figure 3-23. Set point profiles with up to 63 segments can be
specified using the instrument. Note that when a segment depicts the process value as sloping up or
down, it is referred to as a “ramp.” The term “soak” is used to describe a segment when the process
value is made to stay constant. In Figure 3-23, segments 1, 3, and 5 are ramps while segments 2 and 4
are soaks.
PROCESS

ENGINEERING
UNITS

TIME
Figure 3-23 Example Set Point Profile
To force a process value to vary linearly with time at various rates within successive time intervals is the
job of a set point profiler, another class of function blocks available within the instrument. Be advised
that use of set point profilers is typically observed in thermal or heat treat applications. For example,
being able to vary temperature in accordance with a set point profile is vital in the tempering of metal or
ceramic parts.
Refer to the application of Figure 3-11 discussed at the beginning of this section. This application dealt
with controlling a furnace zone’s temperature by means of a 4 to 20 mA gas valve actuator. If the
furnace zone temperature were to be manipulated so that it followed the ramps and soaks of a set point
profile, the first step would be to implement the function block diagram established in Figure 3-16In
general, the control configuration that holds a process value to a local set point, must be programmed
and on line before allowing the process value to be characterized by a profile. With regard to the
application at hand, a set point profiler function block programmed with a user defined set point profile
may be brought into the configuration once the furnace zone’s basic temperature control loop is
operational. Note that the output of the profiler function block will essentially be the set point profile.
From the cascade control strategy’s explanation, recall that all control loop function blocks within the
instrument have a Setpoint #2 parameter that may be used as a remote set point input for connecting to
the profiler’s output.
LP1 in the function block diagram of Figure 3-16 will make use of SP2’s remote set point functionality so
that a set point profiler’s time varying set point may be applied to it. Refer to Figure 3-24.

Figure 3-24 basically depicts all the components of the Figure 3-16’s control configuration with a set
point profiler function block denoted by SP1. The profiler’s output (SP1 OV) is connected to the remote
set point input of LP1. Depending on the model number of the instrument, up to four set point profiler
function blocks (SP1 through SP4) may be included within the instrument’s feature capacities. Note that
while the profiler of SP1 was specified in Figure 3-24’s diagram, any of the profilers within the instrument
could have been used.
When a set point profile is executed, discrete inputs are typically used in conjunction with external
switches to control the set point profiler function block. For example, the set point profiler function block
can be programmed to start, hold, or reset based on discrete input statuses. See Figure 3-25.

Also typical in the execution of a set point profile is the generation of discrete events during each profile
step. Discrete events are simply status indicators that are programmed to assume either an ON or OFF
state during a step of a profile. As simple discrete status indicators, these events may, for example, be
used to initiate a logic control scheme on the process being controlled upon the occurrence of a
particular profile segment. In this product, note that up to 16 discrete events may be programmed per

3.15 Data Storage
This instrument supports either floppy 1,44 MB or 100 MB ZIP disks. Note that only DOS formatted
floppy disks may be used in the instrument’s disk drive and the unit’s front door must be closed for any
disk drive operations to take place. The floppy disks may be initialized in the instrument or on an IBM-
PC with the initialize utility.
Read this overview thoroughly to understand the fundamentals behind the instrument’s data storage
capabilities.
Categories of Stored Data
There are four categories of disk storable data. Each category of data is stored in its own unique file.
The categories are:
Data Storage
Configuration Storage
Setpoint Program Storage
Calibration Storage
Data Storage Configuratio n CalibrationSetpoint Program
Process Data Diagnostic Data
Trends
Unit Data
Ala rm s
Eve nts
Figure 3-28 Categories of Stored Data
The first category of stored data, Data Storage, is comprised of two types of data: process data and
diagnostic data. When the instrument stores these data types it is essentially functioning as a recorder.
Process data is comprised of up to four files containing historical information on the process that the
instrument is monitoring and/or controlling, such as the temperature trend or a log of a furnace over time.
Process data also includes any alarm or discrete event information.
Diagnostic data is the result of the instrument’s execution of diagnostic routines during instrument start-
up and maintenance procedures (such as calibration). Online operation is also monitored to detect both
process faults and internal electronic errors. If a diagnostic error occurs, a record of it can be stored to a
single diagnostic file.
The second category of stored data is configuration storage, which is a single file comprised of the
instrument’s programming and configuration. Configuration storage includes the programming of the
instrument’s analog input characteristics, the configuration of its control loops, or, perhaps, the
programming of any math or logic functions.
The third category of stored data is Setpoint Program storage, which is a single file –a setpoint program–
containing one to eight setpoint profiles, depending on the instrument. Recall that set point profiles are
user specified plots of process values against time that are divided into ramp and soak segments of
varying time lengths. Setpoint programs may be stored to disk or to the instrument’s memory.
The fourth category of stored data is calibration storage, which is a file containing the instrument’s
analog input and output calibration. This file may be used to restore calibration in the event that a full
calibration, using a calibration source and/or meter, cannot be performed.
Programming and Operating Concepts
Video Recorder – User Manual 75
Performing Data Storage
Configuring the instrument to store the first category, Data Storage (process and diagnostic data) is done
through an Online menu entitled DATA STORAGE. All aspects of preparing a DOS formatted disk to
accept process and diagnostic data information are managed through this menu’s selections. Process
and diagnostic data may be stored on the same disk, but not along with other storage types (i.e.,
configuration, setpoint programs, or calibration).
The four types of process data are:
Trends - Data comprising the classic horizontal or vertically oriented time-varying traces that represent
process parameters.
Unit Data - Process parameter information collected and displayed in tabular or datalog format.
Alarms - A record of any alarms that activated while the instrument was monitoring and/or controlling
your process.
Events - A record of any discrete events that might have occurred while the instrument was monitoring
and/or controlling your process. Discrete events may occur, for example, in the instrument’s execution of
a set point profile.
When the instrument is On line and performing Data Storage, a separate and distinct disk file will be
established for each process data type along with a file for diagnostic errors. Each file will be
distinguished by a file extension as indicated in Table 3-11.
Table 3-11 Data Storage File Extensions
Data Type File extension
Trends .LNT
Unit Data .LNU
Alarm History .LNA
Discrete Event .LNE
Diagnostics .LND
You can specify which process data types are written to disk and whether or not diagnostic errors are
stored by setting up data storage schedules, accessible under a prompt entitled SET UP NEW
SCHEDULES under the DATA STORAGE menu. Up to Eight files may be written to disk while the
instrument performs Data Storage – four trend files, one unit data file, one alarm file, one event file, and
one diagnostics file.
SET UP NEW SCHEDULES lets you designate several other parameters, such as the data storage rate
(i.e., the distance in time between adjacent samples of a recorded process data parameter), the eight-
character file names used to identify each process and diagnostic data file, and whether or not the Data
Storage takes place in continuous or batch modes. Data Storage files may be configured to “rollover”
after they have become full. That is, after the space on the disk for each file type has run out, all of the
oldest data on the disk is overwritten with the most recent data.
Programming and Operating Concepts
Video Recorder – User Manual 76
Initializing a ZIP disk
To activate the new data storage schedules that have been configured in the SET UP NEW
SCHEDULES menu requires you to “initialize” the DOS formatted disk to which process and diagnostic
data will be stored. This is done by executing a routine entitled INITIALIZE DISK, also found in the
DATA STORAGE menu. This task can also be done on a PC. The task of initializing a disk and
activating data storage schedules are one in the same.
ATTENTION
Initializing a disk is only necessary for performing Data Storage. You do not have to initialize a disk to perform
Configuration, Set Point Program, or Calibration Storage
When executing the INITIALIZE DISK menu prompt, you will observe two selections: USE NEW
SCHEDULES and USE CURRENT SCHEDULES. The “SCHEDULES” in both selections refer to the
data storage schedules prepared in the SET UP NEW SCHEDULES menu described earlier. USE NEW
SCHEDULES to initialize the disk to activate a newly configured data storage schedule for the very first
time. The only time you will USE NEW SCHEDULES again is after you have made any changes to the
way the data storage schedules have been configured. You must USE NEW SCHEDULES to initialize
the disk in order for these changes to take effect. USE CURRENT SCHEDULES to initialize a disk if the
disk will replace one that has become full. This will ensure that data being recorded continues
uninterrupted over the space of both the full and replacement disks. During the time when the full disk is
being replaced with a new disk, recorded data will be stored to the instrument’s memory buffer. Upon
completing initialization via the USE CURRENT SCHEDULES prompt, all buffered data will be written to
the new disk and data storage will resume, with no lapses of storage between disks.
Disk initialization allocates sections of the disk to each of the files you have elected to store per the SET
UP NEW SCHEDULES menu. Once the instrument completes initializing the disk, process and
diagnostic data recording begins immediately, indicated by a yellow-colored letter “S” in the lower right
hand corner of the instrument screen.
Pre-initializing a ZIPdisk on a PC
Pre-initializing a ZIP disk on the video recorder takes time, there is a more efficient way to do it : using
theSDI tool. The SDI tool is a very basic, straightforward Win 95/98/NT program that can be used to
quickly pre-initialize a ZIP disk on a PC. This tool is provided with the video recorder. Install it on your
PC, as per instructions on the floppy disk label.
Here are the 3 steps to follow when running the SDI utility.
Select the drive letter where the
disk to initialize can be found
Select the number of trend

Click on initialize

Programming and Operating Concepts
Video Recorder – User Manual 77
The next step to complete is to initialize the disk on the video recorder as you would have done normally,
as explained in the «Initializing a zip disk» section, except that this time, it will take just a few seconds.
Note: it is recommended to dedicate a ZIP disk to storage of data only and store configurations of
products on a separate disk.
Data Storage Status
The prompt DATA STORAGE STATUS, accessed from the Online DATA STORAGE menu item,
displays a calculation of how long a particular disk will last based on the configured data storage
schedule. Disk capacity is indicated in days, hours, and minutes remaining on the disk.
After the instrument has been Online and actively performing Data Storage to disk, a warning message
will appear when the disk reaches the default 90% capacity, or a user-specified capacity. Once a disk
has reached its programmed capacity, a DISK FULL message will be displayed.
Data storage considerations
In order to guarantee a proper operation of the instrument (e.g. no sample lost), there is a maximum load
that the video recorder should not overcome. This load can be theorically computed by considering the
number of data storage trends, live trends and live screens programmed and their associated sample
rate.
1 ) One live screen counts for one schedule per second. At least one live screen is present in the
instrument. A live screen is a display that require any measurement information to be built.
2 ) Each ENABLED Data Storage schedule has a user defined sample rate.
3 ) Each ENABLED Live Trend has the following sample rates :
Screen Size Schedule Sample Rate
5 Min Screen 1 Second
15 Minute Screen 3 Seconds
30 Minute Screen 6 Seconds
1 Hour 12 Seconds
2 Hours 24 Seconds
4 Hours 47 Seconds
8 Hours 93 Seconds (1.55 Minutes)
24 Hours 279 Seconds (4.65 Minutes)
7 Days 1951 Seconds (32.5 Minutes)
31 Days 8640 Seconds (2.4 Hours)
Therefore, to guarantee a proper operation of the instrument, the following inequation should allways be

Screen.
The result = (1/1 * 2) + 1/0.25 + 1 = 7 (ABOVE THE LIMIT)
Process and Diagnostic Data Integrity
The instrument is equipped with several features to ensure data integrity. The instrument will not store
data to disk if its front door is open. A BEZEL OPEN message will appear on all displays and process
and diagnostic data meant for disk storage will be kept in the instrument’s memory buffer. Data
corruption and loss are, therefore, not issues if someone walks up to the instrument and simply removes
the Data Storage disk. Note that when performing Data Storage, the instrument writes to the disk only
once a minute. This ensures that the latest data is always on disk. In the event of a power failure, at
most one minute of data would be lost.
Performing Configuration Storage
Configuration storage is performed through a Program mode MAIN MENU prompt LOAD/STORE
CONFIG. Here, a file containing the instrument’s programming and configuration is created by executing
a routine called STORE CONFIG TO DISK. The applicable file extensions for configuration files are
.LNC.
Note that an instrument configuration file may also be created and stored to disk using optionally
purchased SCF Configuration Software. You do not need a live instrument to create a configuration file
using SCF.
Once stored to disk, the instrument configuration file may be downloaded into other instruments that
have an identical model number. This helps to greatly reduce the amount of time required to program
and configure multiple units sharing the same application. Having the instrument configuration on disk
can also drastically minimize down time in the event of an instrument failure. The file can be used to
program and configure a replacement unit within seconds.
Performing Set Point Program Storage

4.2 Programming tips
See Section 3 for general programming procedures.
Before programming a function block’s input parameter with a CV’s (Calculated Value) output
parameter, you must program the CV first; otherwise, the CV’s output parameter will not be
available for programming.
The function block SY (System Parameter) operates internally and has no menu. It automatically
produces outputs which reflect the status of alarms, data storage, diagnostics, and reference
junction temperature. These outputs can be programmed as inputs to function blocks. See Table
3-5 in Section 3.
Each function block can be labeled with custom descriptors and tags to identify the function on
displays. You can enter these labels under the menu item ENTER LABELS or within each function
block’s menu item. See Section 4.4 Frequently used programming prompts.
All Program mode menu items and settings can be reviewed but not changed in the Online mode
by selecting “REVIEW PROGRAMMING” on the main Online menu. See Enable Features, Section
4.19.
We recommend you save the instrument configuration to a floppy disk after you have completed
programming the instrument. See 4.23 Access LOAD/STORE CONFIG.

4.6 Enter Labels
Overview
Labeling lets you use the front panel buttons, a QWERTY keyboard, or barcode reader to assign
custom text identifiers to most data and functions to make them easily recognized on displays. Labeling
items makes programming and operation easier but is not required. You can assign all labels here or at
each individual programming menu (that is, at Program Analog Inputs, Program Alarms, etc.). For the
latter, you must enable labeling under ENABLE FEATURES in the main Program menu.
Entering labels with the front panel buttons
Use the Up Arrow and Down Arrow keys to select a character and the left arrow to move the cursor.
See Table 3-6 for these buttons’ functions. If you are entering several labels, this method can be
tedious because you must scroll through A-Z and 0-9 to pick each character. Consider using a
keyboard or barcode reader instead.
Entering labels with a QWERTY keyboard
Using a QWERTY keyboard is easier and faster if you are entering many labels. See Section 3.6 for
keyboard connection procedure.
To enter label with the keyboard:
1. Select Enter Labels.
2. Select the function block whose label you want to change.
3. Select the label you want to change (Table 4-3).
4. Press Enter to move cursor to the right side of the display.
5. Type in the new label with the keyboard. The instrument accepts A…Z, a…z, 0…9, (,), -, +, /, *, ^,
(.), =.
6. Press Enter to accept the new label.
Entering labels with a barcode reader
Using a barcode reader is easier and faster if you are entering many labels. See Section 3.6 for
barcode reader connection procedure.
To enter label with the barcode reader:
1. Select Enter Labels.
2. Select the function block whose label you want to change.
3. Select the label you want to change (Table 4-3).
4. Press Enter to move cursor to the right side of the display.
5. Scan in the new label with the barcode reader. Allowable characters are: 0…9, A…Z, -, +, /,
6. Press Enter to accept the new label.
After selecting ENTER LABELS, choose an item (such as Analog Inputs) to label. Use the prompts in
Table 4-3. All text and numeric keys may be used for labels; no characters are prohibited. To cancel an
entry, press the ESC key on the keyboard or press the Menu button on the front panel.

4.8 Program Control Loops
Control Loop Programming Structure
Programming a control loop requires configuring at least 3 function blocks: an Analog Input (AI), a loop
algorithm and an Analog Output (AO). The term AO is applied to any type of control output; current
(CAT), or time proportioning (DAT). The structure of the instrument permits many variations on this
concept by allowing Calculated Values (CVs), both digital and analog, to be used as inputs to the
different parameters within the control algorithms. It also allows a single parameter to be read by any
number of function blocks in the unit.
Loop Characteristics
Table 4-8 lists loop characteristics to be aware of when configuring your instrument.
Table 4-8 Loop Characteristics
Characteristic What to be aware of
Choice of algorithm type Two PID algorithm types, interactive and noninteractive. Noninteractive is the
default type; however, this may be changed.
Gain or proportional band PB is the default; however this may be changed.
7 loop types available If the loop type is changed after a configuration is completed, all previously
programmed entries will be deleted.
Diagnostic routines You will be prompted to save your entries when leaving the loop program
sequence. Diagnostic routines are executed at this time to verify all entries are
complete and compatible. A FAIL message at this time may indicate incomplete
entries or incompatible selections.
Split output tuning When programming Split Output control loops, tuning parameter set #1 is
automatically applied to output values between 0 and +100. Tuning parameter
set #2 is automatically applied to output values between 0 and -100.
Programming loop
parameters Control loop programming may require entry of numerical values, analog
parameters or discrete parameters as determined by the specific loop feature. In
some cases the choices may be a numeral, an analog parameter or OFF. For
parameter choices, refer to Table 3-2 for definitions of the discrete and analog
parameter types available. OFF or NONE are listed as menu choices where
applicable. Scroll to locate.
Minimum programming
requirements Many of the prompted entry fields for control loops are optional. As a general
rule, the minimum entry information for control loops includes the Process
Variable (PV) with range limits, set point value, some combination of gain, reset
and rate, and a source for the feedback. In most cases, the feedback source will
be the back-calculation output (BC) value of the analog output (AO) function
block.
Programming Function Blocks and Features
Video Recorder – User Manual 91
Table 4-8 Loop Characteristics (continued)
Characteristic What to be aware of
Split output programming
requirements A splitter output type (Standard or Advanced) calculated value is used to send
the Split loop output to 2 or 3 different analog output (AO) functions. In this
case, program the control loop to receive a feedback from the back calculation
output of the splitter calculated value. In other words, loop Feedback = CVn BC
(where CVn is a Splitter type calculated value and BC is its output).
Program the splitter calculated value to accept the back-calculation values (BC)
of each analog output function block (AO) as its feedback source. In other
words, CVn FB = AOn BC.
Cascade primary loop Be sure to scale the cascade primary loop’s output limits to match the process
variable range of the secondary control loop. (Note: Output scaling is only
available on the cascade primary type of control loop.) The primary loop
feedback should be connected to the back calculation value of the secondary
control loop.
Miscellaneous loop
characteristics Other parameters affecting loops are latching and reset limit. These are
described in the loop prompt table.
Programming Procedure
To program Control Loops, select "PROGRAM CONTROL LOOPS" in the Main Program Menu. Select
a loop to program.
Table 4-9 illustrates the menu selections for the various loop types. See Table 4-10 for an alphabetical
listing of these parameters’ descriptions. Enter all desired choices, then repeat the procedure, if
desired, for the other Loops.

APPROACH HIGH Enter a value 0.1 to 100 or
OFF. This function affects the process variable approach to set
point when the process variable value is less than the set
point value. The value entered is the percent of span
deviation from set point at which a recalculation of the
loop integral value will occur. Enter a starting value equal
to the proportional band value (1/gain value) x 100 if Gain
is used, or OFF at initial configuration. The value may be
altered Online for final loop tuning. This function is useful
for batch startup from a "cold" condition to control
excessive overshoot when set point is reached.
APPROACH LOW Enter a value 0.1 to 100 or
OFF. Affects the process variable approach to set point when
the process variable value is greater than the set point
value.
AUTO/MAN SELECT OFF, discrete parameter, 0, 1 This parameter takes the place of the Auto/Man button
when the DISCR VS KEY SEL discrete is ON (1).
AUTO/MAN SELECT = ON(1) = Manual mode
AUTO/MAN SELECT = OFF (0) = Automatic mode
When DISCR VS KEY SEL is OFF(0), AUTO/MAN SEL
has no effect.
CHG ACTION INPUT OFF, discrete parameter, 0, 1 Change Action Input. Selects the opposite control action
from that selected for the control action (see CONTROL
ACTION). Control action is opposite when the discrete
value is ON or "1".
CONTROL ACTION Reverse (REV) or Direct (DIR)
Acting Control. When Reverse Acting Control is selected, the loop output
will increase as the process variable becomes less than
set point, and will decrease as it becomes greater than
the set point. When Direct Acting Control is selected, the
output action is opposite.
DISCR VS KEY SEL OFF, discrete parameter, 0, 1 Discrete vs. Keyboard select. When this discrete is ON
(1), the Auto/Man and Set point buttons are disabled; their
functioning is transferred to the AUTO/MAN SELECT and
SETPOINT SELECT discretes. See AUTO/MAN SELECT
and SETPOINT SELECT. Status changes made by
AUTO/MAN SELECT and SETPOINT SELECT will remain
when DISCR VS KEY SEL is OFF (0).
DUAL TUNING SEL OFF, discrete parameter, 0, 1 When ON(1), selects the second set of tuning constants
(#2). A bumpless transfer (integral term adjusted)
calculation will be made on transition.

UNITS Select letter Units of measure for values of process variable or set point
which will appear on Online loop displays.
FEEDBACK OFF, analog parameter,
number Provides verification to the loop that the loop output request
(LP OV) was achieved by the analog output module (AO).
Feedback sources are typically pointed to the associated
Back Calculation Value (BC) of an analog output module.
Feedback inputs must have a span equal to the loop output
span when they are not pointed directly to analog output
modules.
FEEDFORWARD OFF, analog parameter,
number Modifies the control loop output independent of the PID
calculation. The range of the value should not exceed 0 to
100 units. Feedforward is typically used to provide an output
change in anticipation of a change to the loop process
variable.
FEEDFORWARD
GAIN -10.00 to 10.00 Applies gain to the feedforward input value.
FORCE REMOTE
MAN OFF, discrete parameter, 0,
1 When discrete is ON(1), forces loop from automatic mode to
remote manual mode. In remote manual, loop output is
determined by the OUTPUT TRACKING value and the local
Down Arrow and Up Arrow buttons for manual output
adjustment are disabled. In remote manual the automatic
indicator (AUTO) of the display will flash. Selecting Manual
mode from the Auto/Manual button will override remote
manual operation.
When the loop’s Set point #2 is programmed as the Set point
Profiler (SPn OV), Force Remote manual should be
programmed as OFF.
GAIN/PROP BAND PB or GAIN Select whether gain or proportional band will be used for
tuning the control loop.
GAIN#1 OR GAIN#2 Enter a value of 0.1 to 200
for Gain, or 0.5 to 1000.0 for
Proportional Band. Enter
OFF to allow integral only
control. (Variable Gain1 or
PB1 is available by
programming a constant's
Destination with GN or PB.
See Program Constants,
Section 4.16.)
Gain is the proportional gain entry for the control loop (The
value entered here is the gain applied to the error signal to
determine the loop output). For example, a 10% change in
process variable (with respect to the input range) from a
balanced condition will result in a 10% change in output,
when a gain of 1.0 is used. Enter a starting value at initial
configuration. The value may be altered Online for final loop
tuning. If an indirect source is specified as in an adaptive
gain configuration, the value can only be altered at the
source.
Gain and Proportional Band are interchangeable values
(Proportional Band = 100/Gain). For loops with dual tuning,
Gain 1 is the gain for the first set of tuning parameters. Gain
2 is for the second set.
HYSTERESIS Enter 0-100% of PV span Deadband value prevents excessive output oscillation when
using ON/OFF control.

IN DECIMAL
POSITION Select decimal position Used for all input parameters of the loop.
INTERACTIVE YES, NO Select interactive (YES) or noninteractive (NO) for the control
algorithm operation. Interactive causes the Gain, Rate, and
Reset terms to interact to make up the proportional term of

the proportional term is simply related to Gain.
LATCHING YES, NO Select the desired action required after a failure to the
failsafe status.
When the loop’s PV or Set point #2 fails, the downstream
function block activates its failsafe (See Table 9-3, Default
condition column). If latching = YES, when the failure is
corrected the operator must take specific action to cancel
these failsafe measures and return the loop to normal
operation. (See Table 9-3 for action needed.) If latching =
NO, when the failure is corrected the loop will automatically
return to normal operation with no action needed by the
operator.

RATE#2 0.02-10.00 minutes Modifies the loop output based on the rate of change of the
process variable. The output is modified by a value that
assumes the rate of change of the process variable will
continue for the time period specified. Enter a starting value
or OFF at the time of configuration. The value may be altered
Online for final loop tuning. For loops with dual tuning, Rate 1
is the rate for the first set of tuning parameters. Rate 2 is for
the second set. (Variable Rate1 is available by programming

See Program Constants, Section 4.16.)
A value of OFF may be entered to allow proportional-only
control. When turned off, the manual reset value determines
the loop output at set point. Bumpless manual to automatic
transfer is canceled when proportional only control is
selected.
RESET LIMIT OFF or 100 to 200%. This value restricts the calculated integral value of the loop
during Cold Start or on a manual-to-automatic transfer.
RATIO BIAS Enter a bias value to be used in calculating the working set
point of the ratio control loop. This is essentially a value that
will be added to the product that results when RATIO
SETPOINT is multiplied by the ratio loop’s wild variable input
value. For example, in the fuel-air ratio control scenario
introduced in the RATIO SETPOINT section, suppose fuel
flow is the wild variable that measured to be 60. With the
RATIO SETPOINT prompt set to 0.5, the result will be 30
when the RATIO SETPOINT is multiplied by the fuel flow. If
the RATIO BIAS prompt is then set to 10, the actual set point
that the ratio loop will use to control air flow will be 30 + 10 =
40.
To make a ratio control loop’s working set point equal to:
(RATIO SETPOINT x Wild Variable value) + RATIO BIAS
the loop’s working set point must be toggled to SP2 using the
“SP (Set Point select)” key while viewing the loop’s ON LINE
display. Refer to Figure 4-1.

Table 4-10 Loop Prompts (continued)
Prompt Range/Selections Definition
RATIO SETPOINT Enter a number will equal the ratio that the ratio control loop
will maintain between its process variable and a “wild
variable.” The wild variable may be the Output Value of any
analog input or calculated value function block over which the
ration loop will have no control.
The RATIO SETPOINT menu choice is essentially a multiplier
applied to the wild variable’s value. This multiplication’s result
will be a working set point for the loop that will ensure the
desired “process variable-to-wild variable” ratio. For example,
suppose you intend to use the ratio control loop to maintain a
50% fuel-air ratio in the operation of a furnace. If the loop will
be directly controlling air flow (i.e. - air flow will be the loop’s
process variable) and fuel flow will be used as a wild variable
to generate the ratio loop’s working set point, the RATIO
SETPOINT menu choice will have to be set to 0.50. Hence, if
fuel flow is measured to be 60, the working set point that will
be used in the ratio loop’s control of air flow will be (60) x
(0.50) = 30.
To make a ratio control loop’s working set point equal to the
product of RATIO SETPOINT and a specific wild variable
value, the loop’s working set point must be toggled to SP2
using the “SP (Set Point Select)” key while viewing the loop’s
ON LINE display. Refer to Figure 4-1.
SETPOINT SELECT OFF, discrete parameter, 0,
1 When the DISCR VS KEY SEL discrete is ON (1) this
parameter takes the place of the On-Line Tune Loop menu’s
Toggle Set point Source prompt.
SETPOINT SELECT = ON (1) = Set point2
SETPOINT SELECT = OFF (0) = Set point1
When DISCR VS KEY SEL is OFF(0), SETPOINT SELECT
has no effect.
SETPOINT#1 &
SETPOINT#2 Set point #1 can be a
number only. Set point #2
can be a number, an analog
parameter, or OFF.
Set point #1 and #2 are independent set points. Either may be
the active set point for the loop. When viewing a live ON
LINE mode control loop display, a loop may be switched
between SETPOINT #1 and SETPOINT #2 by accessing the
Tune Loop menu and selecting TOGGLE SETPOINT
SOURCE. Operation of the loop using SETPOINT #1 will be
indicated by the presence of an “SP1” symbol on the loop’s
display. “SP2” will be the symbol observed when the loop is
operating using SETPOINT #2.
While SETPOINT #2 may be programmed as a numerical
value, it may also be used as a remote set point input to the
loop. You may link SETPOINT #2 to any of several analog
parameters that include the Output Values of analog input or
calculated value function blocks. If used as a remote set point
input, SETPOINT #2’s value may not be manually changed
from within any live ON LINE mode control loop displays.
SOFT PID YES, NO Soft PID action (YES) causes the control algorithm to not
calculate proportional output corresponding to errors resulting
from changes to set point. The algorithm will adjust its Reset
(Integral) term to a value required to maintain the present
output when the set point is changed. Normal proportional
action should occur for all changes and variations to the
controlled variable.

SP1 TRACKING SP2, NONE A selection of Set point #2 will cause the Set point #1 value to
be set to the Set point #2 value on a transfer from Set point
#2 to Set point #1. Set point #1 adjustment may be made
after the transfer.
SUPPRESS
OVERSHOOT YES, NO This parameter set to YES limits overshoot of the Set point
(SP) by the Process Variable (PV) after a disturbance in the
process such as a load or SP change. Through fuzzy logic,
the working SP of the control loop is dynamically modified by
the control algorithm to reduce or eliminate overshoot.
ATTENTION
Regardless of the setting of this SUPPRESS OVERSHOOT selection, overshoot is not suppressed when the process
disturbance causes an initial deviation (PV-SP) value between -0.7 and +0.7 engineering units. Consequently,
overshoot may not be suppressed in applications which require numerically small control loop PV ranges such as
carbon potential where this range is typically 0.0 to 2.0 engineering units.
WILD VARIABLE Enter an analog input (AIn OV) or calculated value (CVn OV)
parameter that represents a second input signal applied to
the ratio control loop whose value will be multiplied by the
RATIO SETPOINT multiplier. The product of this multiplication
may be specified as the ratio control loop’s working set point
and can be biased by specifying a RATIO BIAS value. This
input parameter is referred to as the “WILD VARIABLE” since
the ratio loop has no control over its value whatsoever. In the
fuel-air ratio control examples used in RATIO SETPOINT
AND RATIO BIAS, fuel flow was for all intents and purposes
the WILD VARIABLE.

represent a ratio control loop is illustrated in Figure 4-1.

Figure 4-1 Function Block Configuration of a Typical Ratio Control Loop
When the ratio control loop in Figure 4-1 is brought ON LINE, its ON LINE display must be accessed to
allow the instrument’s SP (Set Point Select) key to be operational. To make the working set point of the
ratio control loop equal the equation (WILD VARIABLE X RATIO SETPOINT) + RATIO BIAS, then
select the TUNE LOOP menu item TOGGLE SETPOINT SOURCE so that an “SP2” is seen in the loop’s
ON LINE display. Note that within the ratio control loop’s programming menu (accessed under
PROGRAM CONTROL LOOPS), you will not find a SETPOINT #2 menu choice. The ratio control loop
function block operates with the formula (WILD VARIABLE X RATIO SETPOINT ) + RATIO BIAS
assuming all the functionality of the ratio loop’s second set point. Pressing the SP key to switch the
working set point of a live ratio control loop from SP2 to SP1 will essentially suspend any ratio control
and cause the loop to behave like a standard PID controller. This standard PID loop will have a local set
point equal to the value programmed for SETPOINT #1. To control the process variable using a fixed set
point that is independent of the loop’s WILD VARIABLE input, toggle the ratio control loop’s working set
point to SP1.

Example 2
Impulse Time = 150. Min Off Time = 3 seconds. The output
will not turn off unless the input source is 98%. For
instance, if input source = 99%, output would be off for 1% of
impulse time, or 1.5 seconds, but since 1.5 seconds is less
than the Min Off Time, output will not turn off.

Sterilization
The output CVn OV is a “kill time”, F0, which quantifies the destruction of microorganisms during a
sterilization process. F0 represents the number of minutes after which the microorganism population is
decreased by one decimal or log unit. The F0 formula is:
F0 = [dt x (10(T-Tref)/Z)]
where:
dt = time between F0 measurements, in minutes. Dt is equal to the scan cycle of the instrument in
minutes.
T = measured temperature input, in °C
Tref = reference temperature (121°C typical)
Z = product-dependent temperature constant
This function also compares the calculated F0 value to the desired F0 value, Fd (Preset). When F0
equals or exceeds Fd, the function activates its discrete output CVn OS; this output remains ON(1) until
the F0 calculation is reset via the Reset Input.
The output CVn A2 is the Time Remaining (Tr) at the current temperature to achieve Fd and is
calculated as follows:
(Fd – F0)
Tr = _________
10(T-Tref)/Z
The F0 calculation will be reset and the F0 value will remain at zero while the Reset Input is ON(1). The
calculation will resume when the Reset Input goes OFF(0) again.

outputs: CVn_A1, CVn_A2 and CVn_A3 (Figure 4-12). For each output, when the input is between IN
LO LIM and IN HI LIM, the output is scaled between the OUT LO LIM and OUT HI LIM. Each output
holds its OUT LO LIM value when the input < the IN LO LIM value for that output. Each output holds its
OUT HI LIM value when the input > the IN HI LIM value for that output. Output limits (OUT LO LIM &
OUT HI LIM) cannot exceed 100% but can be negatively sloped (OUT HI LIM < OUT LO LIM).

Standard Splitter Output (STD SPLITTER)
This function can be used for heat/cool applications. It is a deadband-based splitter that divides a Split
loop’s output (-100% to +100%) into two outputs CVn A1 and CVn A2, both of which are zero when the
loop output is zero (Figure 4-14). A deadband provides a range of loop output within which both split
outputs remain at zero. For overlapped outputs, use Advanced Splitter. Note: A third output CVnA3 is
displayed Online and should be ignored.

the function outputs a running total TLn OV over time.
ATTENTION
Totalizers which exceed the value 999,999 may only be displayed on the dedicated “Totalizer Display”. If the
value is programmed on other displays or stored to disk, when it exceeds the programmed limits the value may
be truncated and the value will flash.

ACTION UP At each machine scan cycle, an integration of the input is
added to the running total. When this total reaches or
exceeds the preset value (assumed to be in eng. Units), the
discrete output of the totalizer goes high and remains high
for 1 scan cycle. The totalizer then resets and starts again.
The value resets to either zero or the residual total (final
total minus preset) if one exists.
DOWN At each machine scan cycle, an integration of the input is
subtracted from the preset value. When this result reaches
or goes below zero, the discrete output of the totalizer goes
high and remains high for 1 scan cycle. The totalizer then
resets and starts again. The value resets to either the
preset or the residual total (preset plus final total [since final
total is either zero or negative]) if one exists.
DEMAND On Demand. Same as UP, except executes only while the
ON DEMAND INPUT discrete is ON(1). Input is ignored
while ON DEMAND INPUT is OFF(0).
CONTIN Continuous. Same as UP except the total ignores the
PRESET value and integrates “forever” (continuously).

Destination defined
To program Loops and Analog Outputs, you select the Program Control Loops or Program Analog
Outputs from the Program Mode Menu, then program each menu item. Some of these menu items,
such as proportional band or slew limits, are function block parameters; that is, they can be
programmed with numerical values only. A Constant’s DESTINATION overrides that numerical value
with a live value (variable) provided by the Constant’s VALUE.
For example, suppose Loop1’s Gain #1 is programmed as the number 5.00, and Constant 1’s Value is
CV 1 OV, the output of Calculated Value #2. By programming Constant1’s Destination as LP1GN,
Loop1’s Gain #1 will no longer be 5.00 but will be continuously updated by the live value provided by
CV 1 OV.
LP 1
GAIN #1 = 5.00
CV 1 OV
CN 1
VALUECV 1 OV
DEST = LP 1 GN
Figure 4-16 Example of Constant Destination
IMPORTANT
Always be certain that the destination is compatible with its associated loop or analog output. A mismatched
destination can affect your output and can be difficult to diagnose. Examples: If destination is AO1 IT (impulse
time), be sure that AO1 is programmed as a DAT. If destination is LP2 IS, be sure that Loop #2 is a type that
has increased slew limit on its menu.
ATTENTION
If the destination is used, the parameter being overridden by the destination cannot be accessed or changed.
For example, Loop Gain cannot be tuned Online in the TUNE LOOP menu.
If you reprogram destination to another parameter or NONE, the original destination parameter maintains its
last live value as determined by the constant’s value. If you want the destination’s last live value to be zero or
NONE:
1. change the constant value to zero or NONE,
2. change to Online mode for 5 seconds to override the previous live value with zero or NONE,
3. change back to program mode,
4. re-program constant’s destination to NONE.
If you program multiple constants with the same destination, only the highest numbered constant’s
destination takes effect. For example, if Constant #1 and Constant #5 both have destination = AO2 IT, then
only Constant #5’s value is used by AO2 IT.

4.17 Copy Block
Use Copy Block to copy the setup of any function block to another channel of the same function block.
For example, if you have programmed AI1 and want AI2 to have the same settings, use Copy Block. If
desired, you can make program changes to AI2 after the copy is complete.
If your instrument can run multiple profiles at the same time, Copy Block is useful for copying the
parameters of one profile to another. For example, if your instrument can run 2 profiles, it may be useful
to have both profiles use the same switches for starting, holding, and resetting. After you program the

Display Setup Procedure
Table 4-54 describes the display setup procedure.
Table 4-54 Display Setup Procedure
Step Action
1 Select Program Displays from the Program mode menu.
2 For each display format desired (trend, bar graph, panel display, unit data), specify points to be
displayed.
3 Assign up to 10 displays to the Display buttons.
Set Up Trend 1
Table 4-55 describes the trend display setup procedure.
Table 4-55 Set Up Trend 1 Prompts
Prompt Range/Selections Definition
ENABLE Yes, No Enables or disables a specific trend.
POINT #1
POINT #12 Analog or discrete
parameters Select up to 12 analog or discrete points to be displayed as a
vertical or horizontal trend. Trends of discrete points will
show a value of 1 when ON and 0 when OFF.
NORM TIME BASE 5, 15, or 30 minutes, or 1, 2,
4, 8, 24 hours, 7 days or
31 days. Equivalent paper
chart speeds are listed in
Table 4-56.
Enter the trend display time base for Normal (typically slow
speed). The time base is the time period shown for one full
screen.
ALT TIME BASE 5, 15, or 30 minutes, or 1, 2,
4, 8, 24 hours, 7 days or 31
days. Equivalent paper
chart speeds are listed in
Table 4-56.
Enter the trend display time base for Alternate (typically fast
speed). The time base is the time period shown for one full
screen.
SET DISPLAY
LIMITS OFF or number Set the high and low full-scale display limits for each point. If
you select OFF for a limit on this display, the limits
programmed for the analog point (either RANGE LOW and
RANGE HIGH or OUT LOW LIMIT and OUT HIGH LIMIT) will
be used as the trend limits for that point.
The accuracy of a trended point is determined only by the
original output limits of the point, not by setting wider or
narrower limits here. Setting excessively narrower limits here
will result in a viewable trend with a high degree of
inaccuracy when viewed as a % of the screen. To increase
accuracy over a narrower range, decrease the programmed
output range (limits) of the point itself.
TIMEBASE
SELECTOR OFF, discrete parameter, 0,
1 Enter a discrete parameter which will cause trend to display
alternate timebase when ON and normal timebase when
OFF.

See Table 4-55 for prompts. For Point #1 - Point #12, enter a second group of up to 12 points that will
be displayed as a horizontal or vertical trend.
Log scale trending
This feature enables trending of logarithmic trending on the video chart. This feature is enabled by the following
rules :
1. Programming the decimal point for trend point #1 as X.XXEXX and then trend point #1 and any
subsequent trend point that also has X.XXEXX as the decimal point will be plotted logarithmically
with the number of log divisions derived automatically from the low and high limit of point #1.
2. Setting up the trend display limits decimal position to be X.XXEXX and then any trend point that
also has X.XXEXX as its decimal position will be plotted logarithmically with the number of log
divisions derived automatically from the low and high of the first trend point found with X.XXEXX
decimal position.

4.24 Scan Rate
Scan rate is the time required to measure inputs, execute function blocks (AI, Loops, AO, DI, DO, CV,
etc.) and update outputs. It is also known as the machine cycle, scan cycle, and update rate.
The Scan Rate prompt lets you set the scan rate of the instrument to a value slower than the maximum
rate allowed by the hardware. The hardware will determine the default scan rate. Allowable entries are
250 milliseconds, 500 milliseconds, 1 second, 2 or 3 seconds. 250 ms rate is only available on 4 input
units.

5.1 Overview of the Setpoint Profiler
Definitions
A profiler is a Setpoint Profiler function block. This function block is what you interact with when you
program and run a profile. The profiler is analogous to a compact disk player on a stereo, in that the
profiler “plays” a profile. Your instrument contains 1, 2, 3, or 4 profilers, depending on the option
ordered.
A profile is a series of ramp and soak segments, along with any parameters associated with those
segments, such as segment loops, events, and guaranteed soak enables. The setpoint produced by
the profile is used by a control loop’s Setpoint #2. A profile is also known as a curve or recipe. A profile
is analogous to a compact disc, in that the profile is “played” by the profiler. Your instrument contains 1,
2, 3, or 4 profiles, depending on the option ordered.
A program is a set of one to four profiles, depending on the instrument. Programs in a single profile
instrument contain 1 profile, programs in a two-profile instrument contain 2 profiles, programs in a three-
profile instrument contain 3 profiles, and programs in a four-profile instrument contain 4 profiles.
Guaranteed soak is a set of parameters that hold the profiler when the deviation between the generated
setpoint and either PV is larger than a configured limit.
Event outputs are discrete output parameters of the Setpoint Profiler function block. They may be tied
to other function blocks such as Discrete Outputs.
Profile features
Each profile has the following features:
A second PV is available. Each PV is monitored for excessive deviation from the profile value, in
which case the profiler can be automatically put on Hold.
Menu or discrete control of profile resetting, starting, holding, advancing, shutting down, or fast
forwarding through the profile.
Discrete input for starting the profiler at the current value of the process variable. Known as “hot
start.”
Discrete input for enabling/disabling guaranteed soak over the entire profile.
Setpoint Profiler
Video Recorder – User Manual 176
Guaranteed soak configurable per segment.
Discrete outputs to indicate profile state, including Ready, Run, Hold, In Progress, and At End.
Up to 16 Discrete outputs (Events) programmable per segment.
Four user-selectable methods for ramping.
Automatic recycling of the profile.
Up to four levels of looping within profile.

Two types of profiles
A single phase profile is the simpler of the two profile types. It does not contain startup and shutdown
segments. It runs from Segment 1 to the last segment.
A multiphase profile divides the profile into three phases: the startup phase, the batch phase, and the
shutdown phase. With a multiphase profile you can rerun the batch phase multiple times (known as
AUTO CYCLING), or skip to the shutdown phase. The batch phase of a multiphase profile is specified
by the BATCH FIRST SEGMENT and BATCH LAST SEGMENT prompts. See Figure 5-2.

5.2 Components of a profile
Two PVs available
Each profile can monitor up to 2 process variables. The second PV is for monitoring a second variable
related to your process. The value of each PV is compared with the value of the profile. If the
difference between either PV and the profile value exceeds specified amounts, the profiler will Hold
(soak), if enabled to do so.
Number of segments
Up to 63 segments may be in a profile.
Time Units
All segments use the same time base (seconds, minutes, or hours).
4 types of ramp segments
There are four ramp types selectable at the RAMP TYPE prompt.
1. Value/Duration
2. Time
3. Rate
4. External
Value/Duration (Val/Dur)Ramp Type
This is the only ramp type that allows consecutive ramps or soaks. VALUE is the beginning value of the
segment; TIME is the time needed to reach the VALUE of the next segment.

Ramp segments Soak segments
Figure 5-3 Value/Duration Ramp Type
Setpoint Profiler
Video Recorder – User Manual 179
To properly terminate a Val/Dur profile you must program the segment beyond the last segment with
the following:
1. The value you want the program to “end” with. Looking at Figure 5-3, the last segment is a soak,
thus the Value of segment #6 should be set to the same value used in segment #5. Any other value
will cause segment #5 to be a “ramp” since the value will ramp up (or down) from segment #5’s
value to segment #6’s value.
2. Set the TIME to “OFF”.
Time Ramp Type
Each ramp segment’s TIME is the time allotted for the profiler output to reach the next soak segment’s
VALUE. The ramp segment’s VALUE prompt is not used.

External Ramp Type
This ramp type works with the RAMP INCREMENT discrete input. During a ramp segment, each time
RAMP INCREMENT changes from OFF to ON, the profiler output incrementally changes by the amount
specified in the ramp segment’s TIME (in units of the PV). When RAMP INCREMENT changes from ON
to OFF, the profiler output soaks at its present value. This increment-soak repeats until the profiler
output reaches the VALUE of the next soak segment. The ramp segment’s VALUE prompt is not used.

Setpoint Profiler
Video Recorder – User Manual 182
Soak segment
All soak segments have a beginning VALUE and a TIME during which that value is maintained. This is
true regardless of the ramp type used.
Guaranteed Soak
Guaranteed soak will Hold the profile value if either PV to the profile (typically a Control Loop’s PV)
deviates specified amounts above or below the profiler output. See Figure 5-7. For a guaranteed soak
to occur, the following conditions must be met:
1. The GUAR SOAK #1 and GUAR SOAK #2 prompts for the segment (ramps and soaks) must be
enabled (set to ON),
and
2. The GUARANTEED SOAK discrete input to the profile must be enabled (level high).
If either of these are disabled, a guaranteed soak cannot occur, even with excessive deviation between
profile and PV.
Hysteresis
This parameter specifies the amount the deviation between profile and PV must be reduced before the
profile resumes running after a guaranteed soak. See Figure 5-7.
After a guaranteed soak the profile will resume running when the deviation has decreased by this
amount.
The following examples assume GUARANTEED SOAK is ON(1), and the example segment’s GUAR
SOAK #1 is ON(1).
Example #1
Assume PV #1 is 20 units above the profile output, GUAR SOAK HI LIM is 15, HYSTERESIS is 5. The
profile will Hold because the deviation high limit is exceeded. The profile will resume running when the
PV #1 is 10 (15-5) units or less above the profile output.
Example #2
Assume PV #1 is 20 units below the profile output, GUAR SOAK LO LIM is 15, HYSTERESIS is 5. The
profile will Hold because the deviation low limit is exceeded. The profile will resume running when the
PV #1 is 10 (15-5) units or less below the profile output.

Segment Events
Each segment contains 16 programmable discrete event outputs whose ON/OFF states- specified by
you -can be used to trigger other discrete functions. The segment’s event states are activated at the
beginning of the segment and are maintained unless changed by the next segment in the profile. See
Table 5-1. The last segment’s event states are maintained after the profiler is ended.
Table 5-1 Example of Segment Events
Segment #1 Segment #2 Segment #3
Event 1 State 1 (ON) 0 (OFF) 0 (OFF)
Event 2 State 0 (OFF) 1 (ON) 0 (OFF)
Event 3 State 1 (ON) 0 (OFF) 1 (ON)
To activate events in the middle of a ramp segment, replace the desired segment with 3 segments: a
ramp, a very short soak, and another ramp. Program the second and third segment events as if they
were the middle of the segment.

Segment Loops
You can program up to four segment loops within a profile. A segment loop is one or more consecutive
segments which must repeat a selected number of times before proceeding to the next segment outside
of the loop.
Segment loops are specified by the parameters REPEAT COUNT, FROM SEGMENT #, and TO
SEGMENT #. Loops are reset when Auto Cycle is reset and when the profile is reset. Loops can
contain other loops but cannot overlap.

5.3 Parameters that control a profile’s execution
Coordinating operation of multiple profilers
In a multi-profiler instrument the profiles in a program can be totally unrelated to each other, that is, you
can give them different times and settings. If you want the profilers to be coordinated, you must
configure each profiler that way. For example, if you want all your profilers to be started by the same
signal, you must configure each profiler with the same START parameter. The Copy Block function in
the Program menu lets you copy parameters from one profiler to another.
SPP synchronization
Allows a multiple SPP user to synchronize several SPPs for when one enter hold due to a guaranteed
hold, the others will enter hold and when the one that entered hold leaver hold the others will leave hold
also. This is done by using a block output status called SG (status guaranteed hold) that is high when
the block is in guaranteed hold mode. If different SPPs are used, the SPPx SG outputs should run
through an OR block and then the output of the OR block back to the SPPx HOLD input. The SG status
output may be viewed on the discrete status screen.
Discrete inputs
You can program a profiler with discrete inputs that enable you to reset, start, hold, advance, shut down,
or fast forward through the profiler, hot start the profiler from a live process variable, increment a ramp
segment, or enable/disable guaranteed soak. See Table 5-2.
Note that some discretes are edge-sensitive and some are level-sensitive. Edge-sensitive means that
the action is triggered by the discrete’s transition from OFF to ON (rising edge) or from ON to OFF
(falling edge). The changing status is what triggers the action, not the status itself. Some discretes,
such as START, are rising edge-sensitive only and are not affected by a falling edge. When START’s
discrete goes ON, the profiler starts to run; when the discrete goes OFF, the profiler continues running.
Level-sensitive means that one action occurs while the discrete is ON and another action occurs while
the discrete is OFF. The status is what causes the action, not the changing status. Fast forward’s
discrete is level-sensitive; that is, the profiler will run in fast forward while the discrete is ON but not
while it is OFF.

START forces the profiler to start running at
Segment 4 at 100, not at Segment 1 or

FAST
FORWARD FAST FORWARD is a way to test for proper
functioning of the profiler’s events and
outputs, without having to wait for the profiler
to execute at its normal speed.
When FAST FORWARD is ON, the profiler will
run at a speed determined by the TIME
MULTIPLIER parameter. The higher the time
multiplier, the faster the profiler will run.
Fast Forward is activated by a discrete input.
Example
The Programmer is running at a 500msec
scan rate. The TIME MULTIPLIER is set to
60. Therefore the profiler will run 60 times
faster than normal. The profiler will increment
in (500msec x 60) or 30 second increments.
Put another way, every half-second the profiler
will advance 30 seconds.

SHUTDOWN When Shutdown is activated by a discrete
input or by the operator menu, the profiler
jumps from the batch phase to the shutdown
phase of a multiphase profile. The shutdown
phase begins at the segment defined by the
parameter BATCH LAST SEGMENT+1.
Shutdown is useful when you need to shut
down your process without waiting for the
profiler to finish a batch.

Therefore the profiler will run in (500msec x 60)
or 30 second increments.
Running a profiler in FAST FORWARD is a way
to check for proper functioning of the profiler’s
events and outputs, without having to wait for
the profiler to execute at its normal speed.
See Figure 5-11.

How to load programs from memory using Online menu
Programs stored in memory are identified by number (1-48) depending on instrument model number.
Each program stored in memory contains one to four profiles, depending on your instrument. See
Table 5-7.
For example, on an instrument with 3 profiles, you can store Program #1 which contains Profiles #1, #2,
and #3.

How programs are stored on a disk
Programs are saved to disk as a file name, number, and .LNS extension. Unlike memory storage, you can
specify which profiles you want stored as a program. Disk capacity depends on the number of profiles in the
program. See Table 5-11.
For example, on a 4 Programmer instrument, if you want to store Profiles #2, #3, and #4 as a program, you
enter 2 at the prompt STARTING PROFILE #, to indicate that the lowest numbered profile to be stored will be
Profile #2. At the prompt NUMBER OF PROFILES, you enter 3 to indicate that 3 profiles will be stored.
Table 5-10 shows all possible combinations of profiles that can be stored to disk.

6.3 Display Messages and Symbols
Overview
Messages and symbols will appear in different areas of the display to inform the operator of a variety of
conditions. The area across the bottom of the display (Figure 6-6) is reserved for messages that
require the operator to take action. They include Active Alarm Symbols, Diagnostic Messages, and
Data Storage Messages.
Location
The Alarm and Diagnostic messages consist of a symbol on the left side of the display and a text
message next to it on the right. The Data Storage message has no symbol and includes only the text
portion.
Multiple messages
If multiple messages are present simultaneously, they will be arranged in a “cascaded” or “shingled”
arrangement, so that underlying symbols will be visible (data storage on top, diagnostics in the middle,
alarms on bottom).

7.2 Data Storage
Overview
Data Storage lets you store trend data, unit data, alarms, events, and diagnostics for later review
onscreen or on a PC with SDA software or the TrendManager Pro V5 software suite. Setup and
configuration of Data Storage is described in Section 4.26; online operation is described here.
Typical online data storage tasks
1. Removing, installing, and labeling disks.
2. Pre-initializing a disk on a PC (see Section 3.15)
3. Initializing new disk using the current Data Storage setup schedules.
4. Checking current storage setup.
5. Starting and stopping storage (3 methods):
a) Start/stop all storage via ENABLE STORAGE menu.
b) Start/stop a particular storage file’s storage via its external enable discrete.
c) Start/stop all storage batches via BATCH STATE menu item or via BATCH CONTROL discrete.
6. Checking storage status with DATA STORAGE STATUS display.
7. Replaying data stored on disk.
8. Reading data storage messages.
Installing a disk
The disk should be pre-initialized. Pre-initializing may be done at a PC or in the instrument with DATA
STORAGE menu item INITIALIZE DISK. Maintaining a stock of several formatted disks is
recommended to minimize maintenance time on the instrument.
Disks are inserted and removed from the front panel as described in Table 7-2.
Table 7-2 Floppy Disk Insertion/Removal Procedure
Step Action
1 Open the door.
2 Insert the disk into the slot until it catches in place.
3 To remove the disk, press the rectangular button next to the slot. Be sure to label the contents of
each disk.
4 Close the door.
Online Operation Using Menus
Video Recorder – User Manual 223
How data is stored
To provide continuity of storage when the disk is removed, the data storage feature buffers data
internally for a period of time based on the storage rate and amount of storage data. Since storage files
and Setpoint program files may not be stored on the same disk, you can swap the storage disk with a
configuration disk for up to the buffered data time period while loading Setpoint programs without losing
storage data. When the storage disk is re-installed, or when another disk is initialized using the current
schedules, the buffered data will be transferred to the disk.
Initializing a disk
Initialization creates separate areas on the disk for each type of data to be stored. Data types that can
be stored are up to 3 Trends, Alarms, Events, Diagnostics, and Unit Data. You can initialize a disk
using the current storage schedule or using a new storage schedule.
When data storage is active, the instrument determines the status of the disk. Status can be one of the
following possibilities.
Table 7-3 Disk Status
Disk status Result
The “current” disk was inserted
back into the drive. The instrument will resume storage to this disk automatically.
Some other disk was inserted.
That is, disk is blank, contains
old data files or contains
configuration files.
In this case, a DISK NOT CURRENT message is displayed and data is
stored in a buffer, not on the disk.
Initializing a disk using the same storage setup
To continue storing the same data storage schedule on this disk, select the online DATA STORAGE
SETUP menu, select INITIALIZE DISK, then select USE CURRENT SCHEDULES. The instrument will
display a prompt asking for a yes or no response to initialize the disk. Initializing will destroy all
existing information on the disk. To shorten the initialization time, the disk should be pre-initialized on
a PC. With this prompt you can remove a disk inserted by mistake, or deliberately re-use an old disk
containing useless information. If you answer YES, the current schedule will be established on the new
disk, buffered data will be stored to the disk, and if any storage files are in batch mode, the batch
counter will be reset to zero(0).
Initializing a disk using a new storage setup
If you change any part of data storage schedule and you want the changed (new) schedule’s data to be
stored, select the online DATA STORAGE SETUP menu, select INITIALIZE DISK, then select USE
NEW SCHEDULES. To shorten the initialization time, the disk should be pre-initialized on a PC. All data
that was buffered since the previous disk was removed is lost. If you change the schedule but initialize
using the current schedule, the changed (new) schedule is not stored.

Initialization errors
If an initialization error occurs, one of the following messages may appear.
Error message Definition
BEZEL OPEN Disk use is not permitted while the front panel bezel is open. The bezel must be
closed and latched.
WRITE-PROTECTED The write protect tab is set (open) on the floppy disk. The tab must be closed to
permit data storage.
DISK ERRORS The disk installed in the drive is faulty or is not a DOS formatted disk. It must be
formatted before it can be initialized. Formatting can be performed on an IBM
compatible PC or with the FORMAT DISK command in the Data Storage menu.
DISK IS MISSING No disk is installed in the drive.
Checking current storage setup
To see what is being stored and when, select DATA STORAGE SETUP, then select REVIEW
CURRENT SCHEDULES.
Online Operation Using Menus
Video Recorder – User Manual 225
Starting and stopping storage
Data Storage can be started and stopped three ways. At the highest level, the ENABLE STORAGE
menu item enables or disables all data storage. At the next highest level, EXTERNAL ENABLE enables
or disables storage for each file type (Trends #1-3, Alarms, Events, Diagnostics, Unit Data). At the
lowest level, storage for each file type is started and stopped with one of two controls: a menu item
BATCH STATE or a discrete parameter BATCH CONTROL.
Table 7-4 describes each method of starting and stopping storage.
Table 7-4 Storage Start/Stop Controls
Prompt
Comments
ENABLE
STORAGE Acts as a master enable/disable switch for all data storage. Select this item from the
DATA STORAGE menu. Set to ENABLE to allow storage of the current schedule. If this
is set to DISABLE, online data storage cannot take place, even if storage for
individual files is enabled with EXTERNAL ENABLE.
EXTERNAL
ENABLE Acts as a enable (high)/disable (low) switch for each storage file type (trends, alarms,
events, diagnostics, unit data). Any storage file whose external enable is configured with
a discrete will start and stop according to the state of that discrete. This works
independently of batch storage.
BATCH
STATE Acts as a start/stop switch for each storage file type. The ENABLE STORAGE and
EXTERNAL ENABLE both must be enabled for BATCH STATE to function.
Accessed under DATA STORAGE menu. If batch storage mode is configured for any
storage file and if BATCH CONTROL has not been configured with a discrete, then you
can manually start/stop the batches using this selection. The instrument will automatically
assign a number internally to identify the batch for storage. For example, data stored
between the first start and stop is marked as Batch #1. When the next batch starts, the
instrument will increment the batch number. These numbers identify the batches for later
retrieval.
BATCH
CONTROL Accessed under SET UP NEW SCHEDULES. If this item is configured with a discrete, it
will start and stop storage for all storage files configured with batch storage mode. The
ENABLE STORAGE and EXTERNAL ENABLE both must be enabled for BATCH
CONTROL to function. The instrument will automatically assign a number internally to
identify the batch for storage. For example, data stored between the first start and stop is
marked as Batch #1. When the next batch starts, the instrument will increment the batch
number. These numbers identify the batches for later retrieval.
BATCH
NUMBER Accessed under DATA STORAGE. Shows the number (1-255) of the active batch. The
batch number is assigned automatically by the instrument when the batch is started by
either method (BATCH CONTROL or BATCH STATE).

Video Recorder – User Manual 227
ATTENTION
If you are replaying data from a “non-current disk,” keep in mind that the instrument will continue acquiring
data and holding it temporarily in its active memory (RAM) until you insert a proper disk for storage. If you
spend too much time replaying data, the instrument could run out of active memory space. If this occurs, a
storage full warning message will be displayed. See Tables 6-6 and 6-7 for an explanation of the various
warning messages.

7.3 Access Summaries
Summaries are available for all points, alarms and diagnostics in the instrument.
Display alarm summary
Alarms are set up as part of the instrument configuration procedure (Section 4.13). Up to 12 alarms can
be configured.
An alarm can be assigned to any analog data point (Analog Input, Analog Output, or Calculated Value)
and can be one of these types.
Alarm type Function
HIGH Alarm when input value > setpoint value.
LOW Alarm when input value < setpoint value.
DEV (Deviation) Alarm when input value deviates above or below compare point
value by an amount > setpoint value.
HRATE (High Rate) Alarm when input value increases at rate > setpoint value, in units
per minute. Negative rate setpoints are processed as positive
values. May take up to 30 seconds to activate.
LRATE (Low Rate) Alarm when input value decreases at rate > setpoint value, in units
per minute. Negative rate setpoints are processed as positive
values. May take up to 30 seconds to activate.
An alarm programmed with delay will not activate before its delay time. An alarm programmed with
hysteresis will clear after its hysteresis delay.
The alarm will remain active as long as the conditions causing it remain. When the conditions no longer
exist, the alarm will be “cleared” automatically. “Clear” means that the indicators for the particular alarm
on all displays will be removed and the alarm will be removed from the Alarm Summary list.
Online Operation Using Menus
Video Recorder – User Manual 229
What happens during an alarm
A flashing red alarm indicator appears on the bottom of all screens. (The alarm must be
acknowledged to stop the flashing.) On displays where the alarm point appears, the value is red
and a red indicator appears.
The alarm is entered into the active alarm summary which can be viewed at any time. The alarm
summary contains the point identification, a description of the alarm, the sense (high, low rate, etc.),
the time of occurrence and the current value of the point.
When the alarm clears, the time of occurrence and the time of clearing will both be entered into the
Alarm History, which is an ongoing record of the occurrence and clearing of all alarms.
If so configured, the alarm occurrence will also be logged on a summary list stored on floppy disk
(see Data Storage, section 4.26).
If so configured, the alarm triggers a discrete output relay. The relay returns to normal state only
when the alarm is cleared.
Acknowledging alarms
When an alarm occurs, it must be acknowledged by the operator to stop its indicator from flashing.
Acknowledging an alarm does not clear the alarm. See Table 7-6for procedure.
Table 7-6 Alarm Acknowledgment Procedure
Step Action
1 Select ACCESS SUMMARIES from online menu.
2 Select DISPLAY ALARM SUMMARY to display a list of active alarms. Up to 4 pages (14 alarms)
can be listed. Unacknowledged alarms will be flashing. Use the Up Arrow and Down Arrow buttons
to view the various pages of the display, as desired.
Display Alarm Summary can also be accessed by pressing the Display button, if the Alarm Summary
display was assigned to that button. See Section 4.18.
3 Press the Up Arrow or Down Arrow button and a cursor will appear on the display. Use the Up
Arrow or Down Arrow button to position the cursor on a flashing alarm and press Enter to
acknowledge the alarm. The flashing will stop and the cursor will disappear.
If you do not press any button for a period of 5 seconds, the cursor will disappear. This is a safety
feature, because while the cursor is visible on the display, the display is temporarily disabled and a
new alarm will not be shown.
4 If there are more flashing alarms, press the Up Arrow and Down Arrow buttons to restore the cursor.
Display Alarm History
The Alarm History display is a multi-page display which lists information on cleared alarms. The most
recent 25 cleared alarms will be shown, with the oldest being dropped from the list when a new alarm
clears and is logged in.
The Alarm History includes the descriptor and tag identifiers of the alarm, the type (high, low, high rate,
etc.), the setpoint value at the time the alarm occurred and the date and times of the occurrence and
clearing of the alarm (designated as IN and OUT times, respectively).
Use the Up Arrow and Down Arrow buttons to view the various pages of the display, as desired.
Display Diagnostics
A Diagnostic is a displayed error message that indicates a serious error or failure has occurred. See
Section 9 for diagnostic descriptions and possible causes.
Online Operation Using Menus
Video Recorder – User Manual 230
What happens during a diagnostic
A flashing blue diagnostic indicator will appear on the bottom of the screen.
The diagnostic message will be entered into the diagnostic summary which can be viewed at any
time. The summary contains each message and the date and time of occurrence.
If Data Storage is set up accordingly, the diagnostic occurrence will also be logged on a summary
list stored on floppy disk.
The diagnostic summary can contain a maximum of 50 messages with the newest shown at the top
of the list. As new diagnostics occur beyond 50, the oldest will be dropped from the list. Diagnostic
messages are not automatically removed from the summary if the error condition is corrected. The
list must be deleted from the screen periodically by the operator as described under Delete All
Diagnostics.
Acknowledging Diagnostic Messages
When a diagnostic occurs, it must be acknowledged by the operator to stop its indicator from flashing.
See Table 7-7.
Acknowledging a diagnostic only stops its indicator from flashing; it does not correct the cause of the
diagnostic. You are not required to acknowledge a diagnostic. The flashing can also be stopped if all
diagnostics are erased, using the DELETE ALL DIAGNOSTICS menu selection.
Table 7-7 Diagnostic Acknowledgment Procedure
Step Action
1 Select ACCESS SUMMARIES from the main online menu.
2 Select DISPLAY DIAGNOSTICS to display a list of diagnostics. Unacknowledged diagnostics will be
flashing.
3 Press the Up Arrow or Down Arrow button and a cursor will appear on the display. Use the Up
Arrow or Down Arrow button to position the cursor on a flashing diagnostic and press Enter to
acknowledge the diagnostic. The flashing will stop and the cursor will disappear.
If you do not press any button for a period of 5 seconds, the cursor will disappear. This is a safety
feature, because while the cursor is visible on the display, the display is temporarily disabled and a
new diagnostic will not be shown.
4 If there are more flashing diagnostics, press the Up Arrow and Down Arrow buttons to restore the
cursor.

The STATE indicates ON or OFF. FORCE/RELEASE indicates if the discrete is forced or released
(unforced). To force a discrete, select FORCE ON or FORCE OFF. To release a forced discrete, select
RELEASE. Adjust with Up Arrow and Down Arrow. Press Enter to enter the changes. Press Menu to
leave the menu.
Adjust Analog Inputs
If the AI point has been configured with a pyrometer range, the Input Adjust is applied as a multiplier
(equal to the newly entered value divided by the actual measured valued at the time that the adjustment
is entered). In this case, the Value Adjust is referred to as an “emissivity” adjustment. If the AI point
has been configured with any other range, the value adjust is applied as a bias (equal to the newly
entered value minus the actual measured value at the time that the adjustment is entered).
All points on the display which are currently adjusted will have a Value Adjust Indicator (*) beside the
value.
To adjust a value, select the desired AI and press Enter. Press Enter to highlight the value then use the
Up Arrow, Down Arrow and Enter buttons to change the value on the display. The value can be
changed to any value within the programmed limits of the AI.
To remove the value adjustment, set the value to OFF. The AI will display its current value and the
indicator (*) will be removed.
Set Analog Outputs
This menu item will appear if the optional analog outputs are installed. It lets you adjust various analog
output parameters.
Two output types are available: current output (CAT) and time proportion/duration adjusting (DAT).
Failsafe Value
Enter a value of 0 to 100% or an analog parameter for the initial output. This is the initial output on “cold
start”. If the failsafe value is set to off, the output will go to 0.
Impulse Time
For DAT outputs, use the Up Arrow, Down Arrow and Enter buttons to adjust the impulse time. Impulse
time must be 1 second. Impulse time is the cycle time for on and off cycling of the output. For
example, an impulse time of 150 seconds will cause the output to be on for 75 seconds and off for 75
seconds when the input source is at 50.

Pretune Loop
Pretune calculates optimum values for a loop's Proportional Band/Gain, Reset and Rate by analyzing
the reaction of the loop to a "step change" in setpoint or output. After these new tuning values have
been calculated you have the option of applying (installing) or not applying them to a preselected tune
set of the loop. You can pretune a loop while another loop is pretuning.
To use pretune, your process time constant must be at least 60 seconds. The process time constant is
defined as the time needed for the PV to change by 63% of a step change in the setpoint. For example,
if the setpoint changes instantaneously by 100 degrees, the time constant is the amount of time needed
for the PV to change 63 degrees.
To pretune a loop, select PRETUNE from the TUNE LOOP online menu. Select a loop to tune. Pretune
occurs in 4 stages as indicated by the status. Each status has its own menu. Table 7-10 shows the
stages of pretune.

8.2 Routine Maintenance
CAUTION
Calibrate the instrument routinely to ensure conformity to specifications. Calibration is to be performed by
qualified service personnel only.
Clean the front panel with a damp cloth. If needed, use a detergent containing no abrasives. Always clean
the front panel with the bezel closed. Do not use solvent cleaners.
Failure to comply with these instructions may result in product damage.
8.3 Set Mode
Select this to change the operating mode to Online or Program.
NOTICE
Changing to ONLINE mode by pressing any of the Display buttons can cause incorrect values to be
displayed. The values will correct themselves in a few seconds. To avoid this potential annoyance, change
to online mode through SET MODE instead of through the Display buttons.
8.4 Calibrate Analog Inputs
Note: the unit must be allowed to warm up for 30 minutes at the intended operating temperature prior to
calibration.
Selecting the CALIBRATE ANALOG INPUTS lists a number of calibration functions you can perform.
Selecting the CALIBRATE ANALOG INPUTS again allows you to specify the AI module and channel in
which to calibrate. When you Select Input, you must apply a 0% reference (low point calibration) value to
the terminal block of the module channel. Then select CALIBRATE to start the calibration routine. After
calibration of 0% value is completed, apply a 100% range value to the channel input terminals and then
begin the calibration routine for 100% input (high point calibration).
When 100% range value calibration is completed, the controller compares the new 0% and 100% range
values against the current 0% and 100% values. If the span of the 0% and 100% readings is less than
20% of the sensor range, the new values are rejected and the current calibration is retained.
Each channel must be calibrated for the specific input type to be applied to that channel. Calibration
values can be copied from one channel to all other channels of like input type and range.
NOTE: Signal generators should have an accuracy of at least 0.05 %. The type of wires depends on the
sensor used. Wait for 5 minutes after that particular sensor is connected (for compensation wires only).
WARNING
In thermocouple pay attention to the ambient temperature. If you are using a mV generator instead of
direct thermocouple generator, the leadwires are in copper and you have to subtract from the mV value
the mV corresponding to the ambient temperature of the rear terminals. (This eliminates the effect of
the cold junction compensation).
Failure to comply with these instructions could result in death or serious injury.
Maintenance
Video Recorder – User Manual 246
Additional calibration selections allow you to perform other calibration procedures:
CALIBRATE REFERENCE JUNCTIONS – for calibrating the two Cold Junction (CJ) references on AI
module.
COPY ANALOG INPUT CALIBRATION – for copying calibration values from one AI module channel to
another.
RESET ANALOG INPUT CALIBRATION – to restore AI module channels to their factory calibration.
RESET REF. FUNCTION CALIBRATION – to restore CJ reference to their factory calibration values.
8.5 AO MODULE calibration
Two calibration selections are accessible under the CALIBRATE AO menu selection
CALIBRATE AO CHANNEL – to calibrate the zero offset and span values of the AO module channels to
user-defined values.
RESTORE AO FACTORY CAL – to restore factory calibrated to an AO module channel.
The AO module contains a wire jumper (labeled ST1) on the PWA. Cutting this jumper will prevent any
changes to initial calibration values of the module and prevent any further field calibration.
See Figure 8-1 for the location of the jumper.

First time start occurs when the unit is being powered up for the first time or when the memory clear
services maintenance routing is executed. All configuration and calibration is cleared and all parameters
are set to factory defaults. See “DATABASE SERVICES” Section 8.7.
Cold Start
Cold start occurs when the unit is without power for a period longer than 90 minutes or if the reset unit
maintenance routine is executed. See Section 8.8 Reset Unit. In cold start operation, all RAM buffers
(storage and display) are cleared and accumulated values of some function blocks (Calculated Value
timers, totalizers, and control loop integral) are reset to initial values. The cold start operation retains the
loop operating status of auto or manual and setpoint 1 or setpoint 2. The loop output will be set to zero
(0) unless configured to use a Failsafe value for the analog output.
No Data collected and stored to floppy disk before the onset of cold Start is lost.
Data storage is automatically resumed after a Cold Start; a maximum of 1 minute of buffered data will be
lost due to a Cold Start. If a new disk was inserted into the floppy drive while power was off, you must
initialize the new disk to resume data storage.
Warm Start
If power is off for less than 90 minutes, a warm start will be used during power-up. All buffered data prior
to power loss is retained and accumulated values in Calculated Value timers and totalizers are retained.
Control loop output values are also retained. Setpoint Profilers resume where they left off. If power is off
for more than the warm up start time, a cold start operation will occur.
Warm start times available (in minutes): 1, 2, 3, 4, 5, 10, 15, 20, 30, 60, 90, None

9.2 Loop Error Indicators
When a loop's PV, SP2, or other parameter fails, the loop switches to its default/failsafe condition,
indicated by certain display symbols flashing. To return the loop to its desired condition, correct the
failure. Then, if the loop's LATCHING is NO, the loop will return to normal automatically. If LATCHING
is YES, also perform the action needed to return the loop to normal.

9.3 Error Messages
Overview
Sometimes errors occur while you are programming or loading a configuration into your instrument. In
most cases the instrument displays a descriptive error message. For example, if you try to program a
function block incorrectly, the instrument tells you the problem.
Table 9-4 lists these error messages along with a description of each one and what action to take.
Table 9-4 Error Messages
Error Description User Action
Alarm/Event/Diagnostic burst
and transitions lost The instrument had an
Alarm/Event/Diagnostic burst in the controller
and some transitions were lost.
Inspect the Alarm Summary/History
and the Discrete Summary Screen to
resolve any missing or unresolved
alarms vs their current states. If the
state transition that was missing was
an off state it will be matched and
processed upon the next on-off
transition of the corresponding alarm.
Block Phase Greater Than Block
Period In Periodic Timer CV, the phase (start time)
is greater than the period. For example, the
start time is 8:00 and the period is 4:00.
Change Period to greater than phase
(Start Time) or change Start Time to
less than Period.
Channel Does Not Exist A channel was loaded that does not exist.
For example, you loaded a dual loop
configuration into a single loop instrument.
