Section 1 – Overview
1.1

Introduction

Function

The UDC 3300 is a microprocessor-based stand alone controller. It
combines the highest degree of functionality and operating simplicity
offered in a 1/4 DIN size controller.
With a typical accuracy of ± 0.20 % of span, the UDC 3300 is an ideal
controller for regulating temperature and other process variables in
numerous heating and cooling applications, in metal working, food, and
pharmaceuticals, and testing and environmental work.

Easy to read displays

The dedicated vacuum fluorescent displays with multi-language prompts
make the operator interface easy to read, understand and operate.
Programmed sequences of displays assure quick and accurate entry of all
configurable parameters.

Easy to operate

Simple keystrokes let you select input and range configuration, set the
operating parameters that meet your process control needs now, and
change them later to meet new ones.
The tactile keyboard provides positive operator feedback. Self diagnostics,
fault tolerant design and keyboard security provide maximum assurance
of trouble-free operation.

Mount anywhere

The UDC is industrial control equipment that must be panel mounted.
The wiring terminals must be enclosed within the panel. The UDC is
environmentally hardened and, when suitably enclosed, can be mounted
virtually anywhere in plant or factory; on the wall, in a panel, or even on
the process machine. It withstands ambient temperatures up to 55 °C
(133 °F) and resists the effects of vibration and mechanical shock.

2.4 Wiring
Electrical
considerations

The controller is considered “rack and panel mounted equipment” per
EN 61010-1, Safety Requirements for Electrical Equipment for
Measurement, Control, and Laboratory Use, Part 1: General
Requirements. Conformity with 72/23/EEC, the Low Voltage Directive
requires the user to provide adequate protection against a shock hazard.
The user shall install this controller in an enclosure that limits
OPERATOR access to the rear terminals.

Controller grounding

PROTECTIVE BONDING (grounding) of this controller and the
enclosure in which it is installed shall be in accordance with National and
local electrical codes. To minimize electrical noise and transients that may
adversely affect the system, supplementary bonding of the controller
enclosure to a local ground, using a No. 12 (4 mm2) copper conductor, is
recommended.

Control/alarm circuit
wiring

The insulation of wires connected to the Control/Alarm terminals shall be
rated for the highest voltage involved. Extra Low Voltage (ELV) wiring
(input, current output, and low voltage Control/Alarm circuits) shall be
separated from HAZARDOUS LIVE (>30 Vac, 42.4 Vpeak, or 60 Vdc)
wiring per Table 2-3.

Electrical Noise
Precautions

Electrical noise is composed of unabated electrical signals which produce
undesirable effects in measurements and control circuits.
Digital equipment is especially sensitive to the effects of electrical noise.
Your controller has built-in circuits to reduce the effect of electrical noise
from various sources. If there is a need to further reduce these effects:
• Separate External Wiring - separate connecting wires into bundles (see
Table 2-3) and route the individual bundles through separate conduits
or metal trays.
• Use Suppression Devices - for additional noise protection, you may
want to add suppression devices at the external source. Appropriate
suppression devices are commercially available.
ATTENTION For additional noise information, refer to document
number 51-52-05-01, How to Apply Digital Instrumentation in Severe
Electrical Noise Environments.

Line voltage wiring

This equipment is suitable for connection to 90-264 Vac or 24 Vac/dc,
50/60 Hz, power supply mains. It is the user’s responsibility to provide a
switch and non-time delay (North America), quick-acting, high breaking
capacity, Type F, (Europe) 1/2 A, 250 V fuse(s) or circuit-breaker for 90264 V; or 1 A, 125 V fuse or circuit breaker for 24 Vac/dc operation, as
part of the installation. The switch or circuit-breaker should be located
close to the controller, within easy reach of the operator. The switch or
circuit-breaker should be marked as the disconnecting device for the
controller (4 mm2).
CAUTION

Applying 90-264 Vac to a controller rated for 24 Vac/dc
will severely damage the controller and is a fire and smoke hazard.
When applying power to multiple instruments, make sure that sufficient
current is supplied. Otherwise, the instruments may not start up normally
due to the voltage drop caused by the in-rush current.

How To Get Started

Read the configuration
tips

Read “Configuration Tips” shown on the next page. These tips will help
you to easily and quickly accomplish the tasks at which you will be
working when you configure your controller.

Read configuration
procedure

Read “Configuration Procedure”. This procedure tells you how to
access the Set Up groups, and the Function parameters within each of
these groups that are shown in the Prompt Hierarchy in Figure 3-1.

Set up groups

The Set Up groups and Function parameters are listed in the order of
their appearance. The list includes the name of the prompt, the range of
setting selections available, the factory setting, and the section to
reference for further details, if necessary.

Parameter explanations
or definitions

If you need a detailed explanation of any prompt listed, refer to Section 4
– Configuration Parameter Definitions.
Section 4 lists the Set Up and Function prompts, the selections or range
of settings that you can make for each, plus a detailed explanation or
definition of each parameter.

Configuration record
sheet

Located on the last page of this section is a “Configuration Record
Sheet”. When you make your configuration selections, record them on
this sheet. Then you will have a record of how the controller was
configured.

Configuration Tips

Introduction

Listed below in Table 3-1 are some tips that will help you enter the
configuration data more quickly.
Table 3-1

Configuration Tips

Function

Tip

Displaying Groups Use the SET UP key to display the Set Up groups. The group titles are listed in this
section in the order that they appear in the controller.
Displaying
Functions
Scrolling

Use the FUNCTION

key to display the individual parameters under each group. The

prompts are listed in the order of their appearance in each group.
To get to a Set Up group prompt more quickly, hold the SET UP

key in. To get to a

Function prompt more quickly, hold the FUNCTION key in. The display will scroll through
the parameters.
ATTENTION The prompting scrolls at a rate of 2/3 seconds when the SET UP
FUNCTION

key is held in. Also, [

][

] keys will move group prompts forward or

backward at a rate twice as fast.

Changing values
quickly

When changing the value of a parameter, you can use a single [ ] or [ ] key. Hold the key
in to increase the rate of change. Stop pressing the key for 1/2 second, then press again to
restart at a slow rate.
When changing the value of a parameter, you can adjust a more significant digit in the upper
display by holding in one key [ ] or [ ], and pressing the other [ ] or [ ] at the same time.
The adjustment will move one digit to the left. Press the key again and you will move one
more digit to the left. (Holding the [ ] and [ ] keys down will change the value twice as
quickly.)

Restoring to the
original value
Exiting SET UP
mode

When you change the value or selection of a parameter while in Set Up mode and decide not
to enter it, press RUN/HOLD

once, the original value or selection will be recalled.

To exit Set Up mode, press the LOWER DISPLAY

key. This returns the display to the same

state it was in immediately preceding entry into the Set Up mode.

Timing out from
Set Up mode

If you are in Set Up mode and do not press any keys for 30 seconds, the controller will time
out and revert to the mode and display that was being used prior to entry into Set Up mode.

Key Error

When a key is pressed and the prompt “KEY ERROR” appears in the lower display, it will be
for one of the following reasons:
• parameter not available
• not in Set Up mode, press SET UP

key first

• key malfunction, do keyboard test (operation)
• Individual key locked out

Configuration Procedure

Introduction

Each of the Set Up groups and their functions are pre-configured at the
factory.
The factory settings are shown in Tables 3-3 through 3-18 which follow
this procedure.
If you want to change any of these selections or values, follow the
procedure in Table 3-2. This procedure tells you the keys to press to get to
any Set Up group and any associated Function parameter prompt.
If you need a detailed explanation of any prompt, refer to Section 4 –
Configuration Parameter Definitions.

Procedure

Follow the procedure listed in Table 3-2 to access the Set Up groups and
Function prompts.
ATTENTION The prompting scrolls at a rate of 2/3 seconds when the
SET UP or FUNCTION key is held in. Also, [ ] [ ] keys will move
group prompts forward or backward at a rate twice as fast.

Accutune Set Up Group

Introduction

The Accutune Set Up group offers these selections:
• FUZZY
Fuzzy Overshoot Suppression—Uses fuzzy logic to suppress or
eliminate any overshoot that may occur when the PV approaches
setpoint.
• TUNE
Demand Tuning—The tuning process is initiated through the operator
interface keys or via a digital input (if configured). The algorithm then
calculates new tuning parameters and enters them in the tuning group.
TUNE does operate with 3 Position Step Control.
• SP*
SP Tuning—SP tuning continuously adjusts the PID parameters in
response to setpoint changes. You can select tuning on minimum
setpoint changes of 5 % up to 15 % span. Perform SP tuning after you
have configured the controller.
SP tuning does not operate with 3 Position Step Control algorithm.
• TUN+PV*
or
SP+PV*
PV Tuning—The (TUNE) Demand Tuning or the (SP) Setpoint
Tuning portions of these selections work as stated above. PV Adapt
will occur during Process Variable (PV) disturbances (0.3 % span or
larger) which result from non-linearities, process dynamics, load
changes, or other operating conditions. When this condition exists, the
controller monitors the process response for 1 and 1/2 process cycles
around the setpoint to determine whether there has been a true process
change or a momentary upset.
Process retuning occurs as the process dynamics are learned. When the
process is being learned with possible retune, a t is shown in the upper
left display digit.
*SP + PV Tuning not available on Basic Model DC330B.

Alarms Set Up Group

Introduction

This data deals with the Alarms function that is available with your
controller.
There are two alarms available. Each alarm has two setpoints. You can
configure each of these two setpoints to alarm on one of several events
and you can configure each setpoint to alarm high or low. You can also
configure the two setpoints to alarm on the same event and to alarm both
high and low, if desired.

4.2 Loop 1 Tuning Parameters Set Up Group
Introduction

Tuning consists of establishing the appropriate values for the tuning
constants for a single loop controller. These parameters are also for Loop
1 of a 2-Loop or Cascade control configuration.
The Accutune feature automatically selects Gain, Rate, and Reset.
This section also contains Keyboard Lockout/Security selections.

Set this group last

Because this group contains functions that have to do with security and
lockout, we recommend that you configure this group last, after all the
other configuration data has been loaded.

Parameter
Definition
PROPORTIONAL BAND (simplex) is the percent of the
range of the measured variable for which a proportional
controller will produce a 100 % change in its output.
GAIN is the ratio of output change (%) over the measured
variable change (%) that caused it.
100%
G = PB%
where PB is the proportional band (in %)
If the PB is 20 %, then the Gain is 5. And, at those
settings, a 3 % change in the error signal (SP-PV) will
result in a 15 % change in the controller’s output due to
proportional action. If the Gain is 2, then the PB is 50 %.
Also defined as "HEAT" Gain on Duplex models for
variations of Heat/Cool applications.
The selection of Proportional Band or Gain is made in the
CONTROL parameter group under prompt PBorGAIN.

Definition
RSET MIN = Reset in Minutes per Repeat
RSET RPM = Reset in Repeats per Minute
RESET (Integral Time) adjusts the controller’s output in
accordance with both the size of the deviation
(SP–PV) and the time it lasts. The amount of the
corrective action depends on the value of Gain. The Reset
adjustment is measured as how many times proportional
action is repeated per minute or how many minutes before
one repeat of the proportional action occurs.
Used with control algorithm PID-A or PID-B.
Also defined as "HEAT" Reset on Duplex models for
variations of Heat/Cool applications.
The selection of minutes per repeat or repeats per minute
is made in the CONTROL parameters group under prompt
MINorRPM.

MANUAL RESET is only applicable if you use control
algorithm PD WITH MANUAL RESET in the Algorithm Set

necessarily line out at setpoint, there will be a deviation
(offset) from setpoint. This eliminates the offset and lets
the PV line out at setpoint.

4.4 Setpoint Ramp/Rate/Programming Set Up Group
Introduction

This data deals with enabling Single Setpoint Ramp function or Setpoint
Rate on one or both control loops. You can start or stop the single SP
Ramp by pressing the RUN/HOLD key.
A single setpoint ramp can be configured to occur between the current
local setpoint and a final local setpoint over a time interval of from 1 to
255 minutes.
There is also a configurable rate of change for any local setpoint change.
ATTENTION SP RAMP and SP RATE will probably cause the SP portion
of Accutune to abort. PV Tune will continue to function normally;
however, during tuning (TUNE configuration) SP Ramp and Program are
placed into HOLD until tuning completes.

SETPOINT RAMP FINAL SETPOINT—Enter the value

the setpoint set here when ramp is ended.
ATTENTION If the ramp is on HOLD, the held setpoint can
be changed by the and keys. However, the ramp time
remaining and original ramp rate is not changed.
Therefore, when returning to RUN mode, the setpoint will
ramp at the same rate as previous to the local setpoint
change and will stop if the final setpoint is reached before
the time expires. If the time expires before the final
setpoint is reached, it will jump to the final setpoint.
ATTENTION SP RAMP and SP RATE will cause the SP
portion of Accutune to abort. PV Tune will continue to

TUNE

DEMAND TUNING—If TUNE is selected, and tuning is
initiated through the operator interface or digital input (if
configured), the algorithm calculates new tuning
parameters and enters them into the tuning group. This
tuning requires no process knowledge and does not
require line out for initialization.

SETPOINT TUNING —This selection tunes on setpoint
changes only. It employs time domain analysis to
accelerate line out at any desired setpoint without prior
initialization or process knowledge.
SP is the recommended start-up mode—to be used when
no knowledge of the process tuning values is available. In
the Start-up mode, and after enabling ACCUTUNE, the
operator simply lines out the process variable in manual
mode, selects the desired SP value and switches to
automatic mode.

TUN+PV

DEMAND TUNING PLUS PV ADAPTIVE TUNE—This
selection provides “TUNE” On Demand tuning plus PV
Adaptive tuning whenever a PV process disturbance of
0.3 % span or greater occurs. It will take 1-1/2 process
cycles around setpoint before any process recognition and
re-tuning can occur due to PV disturbances.

CONT ALG

Parameter
Definition
The CONTROL ALGORITHM lets you select the type of
control that is best for your process.

ON-OFF

ON/OFF is the simplest control type. The output can be
either ON (100 %) or OFF (0 %). The Process Variable
(PV) is compared with the setpoint (SP) to determine the
sign of the error (ERROR = PV–SP). The ON/OFF
algorithm operates on the sign of the error signal.
In Direct Acting Control, when the error signal is positive,
the output is 100 %; and when the error signal is negative,
the output is 0 %. If the control action is reverse, the
opposite is true. An adjustable overlap (Hysteresis Band)
is provided between the on and off states.
Other prompts affected: OUT HYST
DUPLEX ON/OFF is an extension of this algorithm when
the output is configured for Duplex. It allows the operation
of a second ON/OFF output. There is a deadband
between the operating ranges of the two inputs and an
adjustable overlap (hysteresis) of the on and off states of
each output. Both Deadband and Hysteresis are
separately adjustable. With no relay action the controller
will read 50 %.
Other prompts affected: OUT HYST and DEADBAND

PID A
ATTENTION PID A should
not be used for Proportional
only action; i.e., no integral
(reset) action. Instead, use
PD+MR with rate set to 0.

Parameter
Definition
PID A is normally used for three-mode control. This means
that the output can be adjusted somewhere between 100
% and 0 %. It applies all three control actions—
Proportional (P), Integral (I), and Derivative (D)—to the
error signal.
Proportional (Gain)—Regulates the controller’s output in
proportion to the error signal (the difference between
Process Variable and Setpoint).
Integral (Reset)—Regulates the controller’s output to the
size of the error and the time the error has existed. (The
amount of corrective action depends on the value of
proportional Gain.)
Derivative (Rate)—Regulates the controller’s output in
proportion to the rate of change of the error. (The amount
of corrective action depends on the value of proportional
Gain.)

PID B

PID B—Unlike the PID A equation, the controller gives
only an integral response to a setpoint change, with no
effect on the output due to the gain or rate action, and it
gives full response to PV changes. Otherwise controller
action is as described for the PID A equation. See note on
PID A.

PD+MR

PD WITH MANUAL RESET is used whenever integral
action is not wanted for automatic control. The equation is
computed with no integral contribution. The MANUAL
RESET, which is operator adjustable, is then added to the
present output to form the controller output.
Switching between manual and automatic mode will be
bumpless.
If you select PD with Manual Reset you can also configure
the following variations:
• PD (Two Mode) control,
• P (Single Mode) control.
Set Rate (D) to 0.

3PSTEP

Parameter
Definition
THREE POSITION STEP—The Three Position Step
Control algorithm allows the control of a valve (or other
actuator) with an electric motor driven by two controller
relay outputs; one to move the motor upscale, the other
downscale without a feedback slidewire linked to the
motor shaft. The deadband is adjustable in the same
manner as the duplex output algorithm.
The Three Position Step Control algorithm provides an
output display (OUT) which is an estimated motor position,
since the motor is not using any slidewire feedback.
Although this output indication is only an approximation, it
is “corrected” each time the controller drives the motor to
one of its stops (0 % or 100 %). It avoids all the control
problems associated with the feedback slidewire (wear,
dirt, noise). When operating in this algorithm, the
estimated OUT display is shown to the nearest percent
(i.e., no decimal).
Refer to the Operation section for motor position displays.
As a customer configurable option, when a second input
board is installed, the motor slidewire can be connected to
the controller. The actual slidewire position is then shown
on the lower display as POS. This value is used for
display only. It is NOT used in the Three Position Step
algorithm. To configure this option, set Input 2 actuation
to SLIDEW. Calibrate the slidewire.

Selections are hardware dependent. For example, if the
controller does not have a current output, then none of the
prompts for Output Algorithms that need a current output
will appear. Likewise, if the controller does not have a
relay output, then none of the prompts that need a relay
output will appear.
ATTENTION For all Duplex Output forms, PID heat
parameters apply for controller output greater than 50 %;
PID cool parameters apply for controller output less than
50 %.

TIME

TIME SIMPLEX—This output algorithm uses Digital
Output 1 for Time Proportional Control. The output is
updated per the Loop sampling rate selection. Time
Proportional Output has a resolution of 4.44 msec. Cycle
Time is adjustable from 1 to 120 seconds.

CURRNT

CURRENT SIMPLEX—Type of output using one 4 mA to
20 mA signal that can be fed into a positive or negative
grounded load of 0 to 1000 ohms. The signal can be
recalibrated for any desired range from 4 mA to 20 mA for
0 % to 100 % output.

CUR D

CURRENT DUPLEX is similar to current simplex but uses
a second current output. The second output is usually
scaled so that zero and span correspond with 0 % and
50 % output (cool zone). When the output is 0 % to 50 %,
the controller uses tuning parameter set #2, when the
output is 50 % to 100 % it uses set #1.
Other prompts affected: 4-20 RNG

CUR TI

CURRENT/TIME DUPLEX is a variation of duplex with
current active for 0 % to 50 % output (tuning set 2) and
time is active 50 % to 100 % output (tuning set 1).
Relay controls heat, current controls cool.
Other prompts affected: 4-20 RNG

TI CUR

TIME CURRENT DUPLEX is similar to CUR TI except that
current is active for 50 % to 100 % and time is active for 0

CURRENT DUPLEX RANGE ALGORITHM — Used with
Output Algorithm selections CUR D, CUR TI, or TI CUR.
50 PCT

CURRENT DUPLEX RANGE (SPLIT)—This setting
should be used for Relay/Current and Current/Relay
Duplex Outputs. It can also be used for Current Duplex
when an Auxiliary Output board is present. This enables
the normal control current output to provide heat control
and the auxiliary current output to provide cool control. To
enable this:
• AUX OUT in the Options Set Up group must be selected
for Output.
• The Auxiliary Current Output is scaled as desired for 050 % controller output.
• Deadband for this configuration only applies to the
Current Output. The Auxiliary Output must have the
Deadband scaled in.
FOR EXAMPLE: If a 2 % Deadband is desired, then enter
2.0 for the Deadband selection in the Control Algorithm
group. This will apply Deadband to the Current Output. In
the Options group, set the Auxiliary Output 4mA VAL
selection to 49.0 and the 20mA VAL selection to 0.0.

100PCT

CURRENT DUPLEX RANGE (FULL) enables the Current
Output to provide both heat and cool functions for control
over 0-100 % of the controller output. The PID heat
parameters apply when the output is greater than 50 %
and the PID cool parameters apply when the output is less
than 50 %. The second current output is not required for
this type of duplex operation.

the first order lag time constant from 1 to 120 seconds. If
you do not want filtering, enter 0.

BURNOUT

BURNOUT PROTECTION (SENSOR BREAK) provides
most input types with upscale or downscale protection if
the input fails.
1-5V, 0-10V, or 4-20 mA inputs require no burnout or
NONE selection.
NONE

NO BURNOUT—Pre-configured Failsafe output applied if
failed input is detected (does not apply for an input out of
range). Error message INPUT 1 FAIL is flashed on the
lower display intermittently every 10 seconds.

UPSCALE BURNOUT will make the PV signal increase to
full scale when a sensor fails, and flash INPUT 1 FAIL on
the lower display intermittently every 10 seconds.
The controller remains in Automatic control mode and
adjusts the controller output signal in response to the full
scale PV signal developed by the Burnout circuitry.

DOWN

DOWNSCALE BURNOUT will make the PV signal
decrease to the lower range value when a sensor fails,
and flash INPUT 1 FAIL on the lower display intermittently
every 10 seconds.
The controller remains in Automatic control mode and
adjusts the controller output signal in response to the zero
percent PV signal developed by the Burnout circuitry.

NO_FS

NO FAILSAFE—This selection does not provide input
failure detection and should only be used when an
absolute accuracy is the most important criteria. (For this
selection, no burnout signal is sent to the sensor.)
ATTENTION For no Burnout, i.e. NONE, to function
properly on a 4-20 mA input, there must be a dropping
resistor directly across the input terminals (i.e., not
remote), then the unit can detect the “zero” voltage that
occurs when the 4-20 mA line is opened.

4.14 Communications Set Up Group
Introduction

This option allows the controller to be connected to a host computer via
RS-422/485 or Modbus protocol.
The controller looks for messages from the computer at regular intervals.
If these messages are not received within the configured shed time, the
controller will SHED from the communications link and return to standalone operation. Depending on the protocol selected, the device address,
parity, and baud rate are configurable. You can also set the SHED output
mode and setpoint recall, and communication units.
Up to 99 addresses can be configured over this link. The number of units
that can be configured depends on the protocol chosen:
• RS-422/485—15 drops maximum
• Modbus—15 drops (or 31 for shorter link length) maximum

4.15 Alarms Set Up Group
Introduction

An alarm is an indication that an event that you have configured (for
example—Process Variable) has exceeded one or more alarm limits. There
are two alarms available. Each alarm has two setpoints. You can configure
each of these two setpoints to alarm on various controller parameters.
There are two alarm output selections, High and Low. You can configure
each setpoint to alarm either High or Low. These are called single alarms.
You can also configure the two setpoints to alarm on the same event and
to alarm both high and low. A single adjustable Hysteresis of 0 % to 100
% is configurable for the alarm setpoint.
See Table 2-8 in the Installation section for Alarm relay contact
information.
The prompts for the Alarm Outputs appear whether or not the alarm relays
are physically present. This allows the Alarm status to be shown on the
display and/or sent via communications to a host computer.

A1S1TYPE to actuate. The value depends on what the
setpoint has been configured to represent. NO setpoint is
required for Communications SHED. For SP Programming
the value is the segment number for which the event
applies.
For Maintenance Timers, the setpoint value is
HOURS.TENTHS OF HOURS. Example: setpoint value
4.2 means 4 hours 12 minutes. (Be aware that the value of
the Timer itself is displayed in HOURS.MINUTES.
Example: 4.2 means 4 hours 2 minutes.)
For Maintenance Counters for output relays 1 and 2, the
setpoint value is in thousands of counts (1 = 1000 counts).
This prompt does not appear for “Alarm on Manual” type

5.3 Entering a Security Code
Introduction

The LOCKOUT feature in the UDC 3300 is used to inhibit changes (via
keyboard) of certain functions or parameters by unauthorized personnel.
There are different levels of LOCKOUT depending on the level of
security required. These levels are:
NONE
CALIB
+CONF
+VIEW
MAX
See Section 4 - Configuration Definitions for details.

Security code numbers

The level of keyboard lockout may be changed in the Set Up mode.
However, knowledge of a security code number (1 to 4095) may be
required to change from one level of lockout to another. When a controller
leaves the factory, it has a security code of 0 which permits changing from
one lockout level to another without entering any other code number.

Procedure

If you require the use of a security code, select a number from 0001 to
4095 and enter it when the lockout level is configured as NONE.
Thereafter, that selected number must be used to change the lockout level
from something other than NONE.
CAUTION

Write the number on the Configuration Record Sheet in the
configuration section so you will have a permanent record.
Use the procedure in Table 5-3 to enter a security code.

5.6 Operating Modes
Available modes

The controller can operate in any of three basic modes:
• Manual—One or Two Loops
• Automatic with Local Setpoint—One or Two Loops
• Automatic with Remote Setpoint—One or Two Loops
• Manual Cascade
• Automatic Cascade
The manual and automatic control modes with Local and Remote setpoint
are standard with the instrument; cascade control is optional.

Mode definitions

Table 5-7 lists the available modes and their definitions.
Table 5-7

Operating Mode Definitions

Operating Mode
MANUAL

Definition
In the manual mode, the operator directly controls the
controller output level. The process variable and the
percent output are displayed. The configured High and Low
Output Limits are disregarded and the operator can change
the output value using the increment and decrement keys to
the limits allowed by the output type (0 % to 100 % for a
time proportioning output or –5 % to 105 % for a current
output).

AUTOMATIC with LOCAL In automatic local mode, the controller operates from the
SETPOINT
local setpoints and automatically adjusts the output to
maintain the setpoint at the desired value.
In this mode you can adjust the setpoint.
See Section 5.7 - Setpoints.
AUTOMATIC with
REMOTE SETPOINT

In automatic remote mode, the controller operates from the
setpoint measured at the Remote setpoint input.
Adjustments are available to ratio this input and add a
constant bias before it is applied to the control equation.
See Section 3 - Configuration, Control Set up group.

MANUAL CASCADE

In the manual cascade mode, both control loops are in
manual although there is still only one output active. This
mode is used to bring both loops into a reasonable
operation area, at which point the unit is placed into the
automatic cascade mode.
If Loop 1 is placed in Manual control mode, then Loop 2, if
in auto, is then placed in a pseudo-manual mode thereby
eliminating output bumps when Loop 1 is returned to
Automatic control mode.

AUTOMATIC CASCADE

156

In Automatic cascade mode, there are two control loops,
with one loop’s output acting as the setpoint for the second
control loop. There is only one physical output in this mode.

What happens when
you change modes

Table 5-8 explains what happens to the controller when you switch from
one mode to another.

Local Setpoint

Description
The Local Setpoint is usually the value previously stored as
the Local Setpoint.
PV tracking is a configurable feature which modifies this.
For this configuration, when a loop is in manual mode, the
local setpoint value tracks the process variable value
continuously.

Manual or Auto Local to
Automatic Remote SP

The Remote Setpoint uses the stored ratio and bias to
calculate the control setpoint.
Auto bias is a configurable feature which modifies this.
When it is selected the transfer from automatic local to
automatic remote or from manual remote to automatic
remote adjusts the bias based on the local setpoint such
that Bias = LSP – (RSP Input x R).

Automatic Remote
Setpoint to Manual or
Auto Local Setpoint

If configured for Local Setpoint Tracking, when the
controller transfers out of remote setpoint the last value of
the control setpoint is inserted into the local setpoint.
If LSP tracking is not configured, the local setpoint will not
be altered when the transfer is made.

Changing local setpoint
1, 2, or 3

Use the procedure in Table 5-11 to change any of the local setpoint
values.
After changing a local setpoint value, if no other key is pressed, a
minimum of 30 seconds time will elapse before the new value is stored in
nonvolatile memory. If power is removed before this time, the new
setpoint value is lost and the previous setpoint value is used at power up.
If after changing the LSP value another key is pressed, then the value is
stored immediately.

5.10 Using Two Sets of Tuning Constants
Introduction

You can use two sets of tuning constants for single output types and
2-loop or cascade control, and choose the way they are to be switched.
(Does not apply for Duplex control.)
The sets can be:
• keyboard selected,
• automatically switched when a predetermined process variable value
is reached,
• automatically switched when a predetermined setpoint value is
reached.
The following procedures show you how to:
• select two sets or gain scheduling,
• set the switch-over value,
• set tuning constant value for each set, and
• switch between two sets via the keyboard (without automatic
switchover)

Select two sets or gain

5.11 Alarm Setpoints
Introduction

An alarm consists of a relay contact and an operator interface indication.
The alarm relay is de-energized if setpoint 1 or setpoint 2 is exceeded.
The alarm relay is energized when the monitored value goes into the
allowed region by more than the hysteresis.
The relay contacts can be wired for normally open (NO) energized or
normally closed (NC) de-energized at the rear terminals. See Table 2-8 in
the Section 2 – Installation for alarm relay contact information.
There are four alarm setpoints, two for each alarm. The type and state
(High or Low) is selected during configuration. See Section 3 –
Configuration for details.

5.12 Two Loops of Control Overview
Introduction

The UDC 3300 can operate using two independent loops of control or
internal Cascade control.
Available only on Expanded Model DC330E-XX-XXX.
TWO INDEPENDENT LOOPS—See Functional Overview Block
Diagrams for Loop 1 and Loop 2 (Figure 5-2) and Table 5-21 for
selections based on these diagrams.
The following rules apply for two independent loops:
• Current output on Loop 2 requires auxiliary output.
• Loop 2 Current Duplex output is limited to 2nd Current output signal
only.
• Loop 2 relay output is always dedicated to relay output 2.
• No Time Duplex outputs on Loop 2.
• No ON/OFF or 3 Position Step algorithms on Loop 2.
• No Position Proportional output is available on 2-loop controllers.
INTERNAL CASCADE CONTROL—See Functional Overview Block
Diagram (Figure 5-3) and Table 5-25 for selections based on these
diagrams.
The following rules apply for internal Cascade control:
• Loop 2 must be the primary loop.
• Loop 1 must be the secondary (internal or slave) loop because all
output forms exist on Loop 1.
• Loop 1 remote setpoint is fixed as Loop 2 output.
• No Position Proportional output is available on cascade controllers.

Selections

Refer to Figures 5-2, 5-3, and 5-4 Block Diagrams and Table 5-21 for
selections based on these diagrams.

Override rules

To Final
Control
Element

24182

The UDC 3300 allows you to select high or low output override. Refer to
Section 3 - Configuration to select High or Low.
The following rules apply for high/low override:
• Only one physical output is required when override is enabled. It is the
output from Loop 1 because Loop 2’s internal output is routed through
the selector.
• Loop 2 output can also be available at all times if desired.
• In Manual mode, the Output may be overridden.
• Does not apply for Three Position Step Control.
• OTI on bottom display shows value of the internal Loop 1 output
before any override.
ATTENTION

The output of the unselected loop tracks the selected loop
to within 5 % when in Auto mode to eliminate windup. This tracking is
done in the direction opposite to the Override Select configuration; i.e., for
High Select, the unselected output tracks within 5 % of lower, and vice
versa.

5.15 Operating Two Loops of Control
Loop operation

Operation of two individual loops of control is identical to operating a
single loop of control except that TUNING 2 group applies to Loop 2 only
and two PID sets, 3 and 4, are available. TUNING group applies to Loop
1 with PID sets 1 and 2 applicable.

Operating modes and
setpoint source

The rules for Auto/Manual modes and changing setpoint sources are the
same as single loop operation.

Keyboard operation

Note that the loop being displayed is the only loop affected by normal
keyboard operation. However, either loop can be reconfigured when in the
Set Up mode regardless of which is being displayed during normal
operation.

Accutune

Two independent loops or cascaded loops can be tuned at the same time,
if configured.

Setpoint ramp or SP
programming

Either loop or both loops can be configured for a single setpoint ramp
operation by enabling the desired loop or loops (see Section 3 –
Configuration).
An “H” or “R” will appear when applicable, depending upon which loop
is being displayed.
The RUN/HOLD operation is shown in Table 5-15 Procedure for Running
a Setpoint Ramp.

Digital inputs (remote
mode switching)

Digital Input 2 is dedicated to Loop 2 and Digital Input 1 is dedicated to
Loop 1 when two loops or Cascade control is configured.

Output override Hi/Lo
select

Output Override allows you to select the higher of Output 1 and Output 2
(Hi Select) or the lower of Output 1 and Output 2 (Lo Select) to appear at
Output 1 terminals to drive the final control element. Refer to Section 5.12
for Override rules and block diagram.
Override prompts appear under the Algorithm Set Up group, function
prompt OUT OVRD.

5.16 Three Position Step Control Algorithm
Introduction

The Three Position Step Control algorithm (Loop 1 only) allows the
control of a valve (or other actuator) with an electric motor driven by two
controller output relays; one to move the motor upscale, the other to move
it downscale, without a feedback slidewire linked to the motor shaft.
Accutune SP or SP+PV tuning does not function with this algorithm.
Accutune TUNE will operate with this algorithm.

Estimated motor
position

Models DC330X-EE-XXX-X0, DC330X-AA-XXX-X0
The Three Position Step control algorithm provides an output display
(OUT) which is an estimated motor position since the motor is not using
any feedback. Although this output indication is only accurate to a few
percent, it is corrected each time the controller drives the motor to one of
its stops (0 % or 100 %).
It avoids all the control problems associated with the feedback slidewire
(wear, dirt, noise). When operating in this algorithm, the estimated “OUT”
display is shown to the nearest percent (i.e. no decimal).

Accurate motor
position

Models DC330X-EE-XXX-X2, DC330X-AA-XXX-X2
In the event that an accurate and repeatable indication in motor position is
required, Position Proportional model’s slidewire input can be used to
read the motor position and display it on the lower display as “POS” while
still operating in the Three Position Step control mode.
The slidewire must be calibrated for this to operate correctly.

Displaying the motor

Table 5-29 lists the procedure for displaying the motor position.

5.17 Input Math Algorithms
Introduction

If selected via Math options, this controller has two input algorithms
available. Each algorithm can be configured to provide a derived
(calculated) PV or a derived remote setpoint. Up to three inputs may be
applied to the calculation. In addition, the two algorithms may be “linked”
to combine two calculations by configuring one algorithm to be an input
to the other algorithm.
Standard functionality:
• Basic models (DC330B) contain as standard: Weighted Average,
Feedforward Summer, Feedforward Multiplier.
• Expanded models (DC330E) provide as standard: Weighted Average,
Feedforward Summer, Feedforward Multiplier, Relative Humidity.
The Math option, which provides additional algorithms plus two
Characterizers, Totalizer, and Gain Scheduling, is available only on
Expanded Model DC330E-XX-XXX.

Input algorithm
selections

Algorithm selections are made in Section 3 – Configuration. The
following function prompts can be found in the Algorithm Set Up group:
IN ALG1
IN ALG2
These selections include the following algorithms:
Weighted Average
Feedforward Summer
Relative Humidity

8-segment
characterization

This is available as part of the Math Algorithm option. Two 8- selections
can made in Section 3 – Configuration; Set Up group ALGORTHM,
under function prompts:
8SEG CH1
Xn VALUE
Yn VALUE
8SEG CH2
Xn VALU2
Yn VALU2
An 8-segment characterizer can be applied to either Input 1, Input 2,
Output 1, or Output 2. When Input 1 or Input 2 is used, the selected
input’s Ratio and Bias are applied to the Xn values.
When one of the loop outputs is selected, the Xn Values are the output
from the control algorithm, and the Yn Output is the final control element
action.
An example of 8-segment characterization is shown in Figure 4-2.

Totalizer function

A Flow Totalizer is available as part of the Math Algorithm option. This
calculates and displays the total flow volume being measured by Input 1.
Alternatively, it can be applied to either Input Algorithm 1 or Input
Algorithm 2 to totalize the compensated flow rate being calculated by the
algorithm.
The totalizer displays the current totalized flow value (up to seven digits
maximum). Seven scaling factors are available (from one to one million).
The desired scaling factor is applied to the calculated value to extend the
maximum total flow range that can be displayed.
Five integration rates are available to match the totalizer rate to the rate
of flow being measured. The rates are:
Engineering units (EU) per second
EU per minute
EU per hour
EU per day
Millions of units per day
The totalizer value is stored in nonvolatile memory once every eight
hours. If power is lost while the totalizer is in operation, the current value
of the totalizer will be lost. When power is restored, the totalizer will
start operation for the last value stored in nonvolatile memory. The Σ
(Sigma) display will blink to indicate this condition. Reset the totalizer.
The totalizer can be reset from the keyboard whenever desired. The
totalizer should always be reset to initialize the counters whenever it is
enabled, otherwise, the “Σ” (Sigma) display will blink.
Refer to Section 3 – Configuration, Set Up group ALGORTHM, function
prompt TOTALIZER to select an application, and the function prompts
that follow TOTALIZER to enter your scale factor and rate of integration.

5.18 Digital Input Option (Remote Switching)
Introduction

The Digital Input option detects the state of external contacts for either of
two inputs. On contact closure, the controller will respond according to
how each digital input is configured. If the controller is configured for
either 2-loop or Cascade control, then switch #1 operates only on Loop 1
and switch #2 operates only on Loop 2.

5.19 Auto/Manual Station
Introduction

When you select “AM STA” (auto manual station) under the Option Set
Up group function prompt “DIG IN1” or “DIG IN2” (digital input option),
contact closure on the selected digital input causes the controller to switch
to Auto/Manual Station mode.

Function

As shown in Figure 5-5, State 2 is the “A/M Station mode” where the
programmable logic controller (PLC) output is sent through the
Auto/Manual Station. You can switch to manual and change the output at
the controller. (It uses PID set 2.)
State 1 is the “Backup PID mode” which is triggered by opening the
digital input. (It uses PID set 1.)

Description

The “AM STA” selection of digital input creates a repeater station when
the digital input is closed. This is accomplished by a multi-selection from
the digital input menu.
• “ACTION” is forced as “DIRECT”.
• “CONT ALG” is forced as “PD+MR”.
• Active setpoint is forced to 2SP.
• The PV is switched to “PV 2IN”.
• The tuning parameters used are the second set of parameters.
When the switch is open the unit becomes a normal controller with
“CONT ALG” of “PID A”, using tuning parameters set 1, SP, PV as IN1
and “DIRECT” or “REVERSE” as selected by customer configuration.
Input 1 is typically the PV of some upper controller and Input 2 is
typically that controller’s output. If the upper control fails, the upper
device or some watchdog opens the digital input switch and UDC 3300
back-up PID A control is active.
When the upper control reactivates, the digital input switch is closed and
the Auto/Manual Station becomes a repeater station and allows the upper
control output signal to pass through.

Configuration

There are some things to consider when configuring the controller.
The PV range stays as the IN1 range, even while IN2 is the PV when the
switch is closed; therefore:
• The IN2 HI must be less than or equal to the IN1 HI.
(Suggest: IN2 HI = 100.0)
• The IN2 LO must be greater than or equal to the IN1 LO.
(Suggest: IN2 LO = 0.0)
• The TUNING GAIN2 must be equal to
(IN1 HI – IN1 LO) / (IN2 HI – IN2 LO).

5.20 Fuzzy Overshoot Suppression
Introduction

Fuzzy Overshoot Suppression minimizes overshoot after a setpoint change
or a process disturbance. This is especially useful in processes which
experience load changes or where even a small overshoot beyond the
setpoint may result in damage or lost product.

How it works

The fuzzy logic observes the speed and direction of the PV signal as it
approaches the setpoint and temporarily modifies the internal controller
response action as necessary to avoid an overshoot. There is no change to
the PID algorithm, and the fuzzy logic does not alter the PID tuning
parameters. This feature can be independently enabled or disabled, as
required by the application, to work with TUNE On-Demand tuning, the
SP tuning algorithm, or Adaptive Tune.

Configuration

To configure this item, refer to Section 3 – Configuration:
• Set Up Group ACCUTUNE
• Function Prompt FUZZY
• Select ENABLE or DISABL (

Setpoint changes can be made during operation. The setpoint at the time tuning
starts is captured and Tune runs until completion, then proceeds to the new SP value
following the completion of tuning.

*SP ADAPT not available on Basic Model DC330B
How TUNE (demand)
tuning works

TUNE tuning provides virtually foolproof, trouble-free on-demand tuning
in the UDC 3300 controller. No knowledge of the process is required at
start-up. The operator simply enters the desired setpoint and initiates the
tuning.
The controller immediately starts controlling to the setpoint while it
identifies the process, calculates the tuning constants and enters them into
the Tuning group, and begins PID control with the correct tuning
parameters. This works with any process, including integrating type
processes, and allows returning at a fixed setpoint.
The tuning sequence will cycle the controller’s output two full cycles
between 0 % and 100 % (or configured output limits) while allowing only
a very small process variable change above and below the SP during each
cycle. The algorithm then calculates new tuning parameters and enters
them into the Tuning group. A large T appears in the upper display while
tuning is active.

• pressing the LOWER DISPLAY

and ▲

keys simultaneously, or

• using the digital input, if configured.

Aborting tuning

If it is necessary to stop or abort the tuning process, press the
MANUAL/AUTO key and the controller will return to manual mode.
You can also disable TUNE or TUN+PV in the ACCUTUNE or
ACCUTUN2 Set Up group.

TUNE for duplex
(heat/cool)

TUNE can be done for applications using duplex (heat/cool) control.
During tuning, Accutune requires that setpoint 1 will cause a Heating
demand, and then the calculated tuning parameters will be automatically
entered as PID set 1. Likewise, it requires that tuning at local setpoint 2
will cause a Cooling demand, and then the cooling parameters will be
entered as PID set 2.
The tuning sequence will cycle the controller’s output two full cycles
between the high output limit and 50 % for HEAT or between 50 % and
the low output limit for COOL while allowing only a small process
variable change above and below the setpoint during each cycle.

Configuring TUNE for
duplex (heat/cool)

To configure this item, refer to Section 3 – Configuration:
• Set Up Group ACCUTUNE
• Function Prompt ACCUTUNE or ACCUTUN2

Action
Heat Zone:
• Adjust Local Setpoint 1 to a value within the Heat zone.
• Put the controller in Automatic mode.
• Press the LOWER DISPLAY

How SP tuning works

SP tuning will continually adjust the Gain or Proportional Band (P), Reset
(I), and Rate (D) tuning constants in response to setpoint changes.
ATTENTION

SP tuning is not available on Basic Model DC330B.

SP tuning handles all Local and Computer setpoint changes. It uses time
domain analysis, and the rule based expert system techniques to identify
the two most dominant process lags plus any dead time. It then
automatically readjusts the PID parameters as necessary. It does this while
controlling to setpoint in automatic (closed loop) control mode.
These calculated PID values can be changed, if desired, whenever the
tuning is not active. Tuning can be aborted by pushing the
MANUAL/AUTO key to return to the manual mode.
Two criteria are available—Normal and Fast—through configuration.
Setpoint changes

4/00

During start-up, or whenever the setpoint changes beyond the “SP
Change” value, SP tuning employs time domain analysis to tune the
process at any desired setpoint without any prior initialization or process
knowledge.

When the T disappears, tuning is completed and final values are entered for
PID set 2 parameters in the Tuning group.

SP tuning after start-up

SP tuning will occur whenever the controller is in automatic mode and a
setpoint change occurs which is greater than the previously configured
minimum setpoint change value.
The controller will delay using any setpoint changes for 30 seconds to
enable it to calculate whether to SP tune or not. But if the controller is
toggled between LSP1 and LSP2 or if any other key (such as LOWER
DISPLAY) is pressed, the setpoint change is immediate.
A large T is displayed in the upper display whenever tuning is in progress.
During this time, no changes to the configuration parameters, including
the setpoint, are permitted.

Aborting SP tuning

4/00

If it is necessary to stop or abort the tuning:
• Press the MANUAL/AUTO key to return to manual mode. This will
cause an immediate abort of tuning.
• Disable SP or SP+PV in the Accutune Set Up group at function prompt
ACCUTUNE or ACCUTUN2.
UDC 3300 Controller Product Manual

199

Retuning

The controller will evaluate current tuning as SP changes occur. When
retuning is required, the controller operates in automatic mode and
identifies new tuning constants. At the point, the T appears and tuning
values are entered and used until retuning occurs again.

TUN+PV or SP+PV
(process variable
disturbance)

The TUNE demand tuning or the SP tuning portions of these selections
work as stated previously.
During process variable (PV) disturbances which result from
nonlinearities, process dynamics, load changes, or other operating
conditions, PV adapt tuning will occur whenever a PV disturbance of
0.3 % span or larger occurs. When this condition exists, the controller
monitors the process response to determine whether there has been a true
process change or a momentary upset. It will take 1 and 1/2 process cycles
around the setpoint before any process recognition can occur to an
oscillating process.
However, if no oscillation occurs, Adaptive may alter the parameters to
speed up or slow down the process response, if it determines the time to
return to the SP is excessive or too fast (overshoot occurs).
For this configuration, the controller operates with only one set of tuning
parameters for each loop. The second set, normally used for duplex output
or for keyboard, PV or SP switching, is not used because Adaptive tune
continually updates the tuning parameters based on the PV deviation.

PV tuning indications

A small t is displayed in the upper display whenever PV adapt mode is in
progress. During this time, changes to the configuration parameters are
permitted. Whenever the t is displayed it signifies that the process
response is being monitored and this may or may not result in parameter
retuning.
The selection of Fast or Normal criteria has no effect on PV adaptive
tuning.

Aborting PV adaptive
tuning

If it is necessary to stop or abort the tuning:
• Press the MANUAL/AUTO key to return to manual mode. This will
cause an immediate abort of tuning.
• Disable TUN+PV or SP+PV in the Accutune Set Up group at function
prompt ACCUTUNE or ACCUTUN2.

5.22 Carbon Potential
Introduction

Figure 5-6 shows a UDC 3300 controller being used to control the carbon
potential of a furnace’s atmosphere. A carbon probe consisting of a ZrO2
sensor and a thermocouple (to measure the temperature at the sensor)
provides two inputs to the controller. The microprocessor-based controller
computes the atmosphere’s actual carbon potential from these two inputs
and compares the computed value with the desired setpoint. As an on-off
or PID control algorithm determines the controller output necessary to
keep the actual carbon potential at the setpoint. Usually only one output is
used to add more or less enriching gas (typically natural gas) to the
furnace’s base atmosphere, which has a relatively low carbon potential.
The enriching gas then raises the carbon potential to the desired level;
however, there are occasions when it is necessary to add dilution air to
lower the carbon potential instead of enriching gas to raise it. In those
instances, a second output from the controller provides this function.
When proportional control is used, a different set of PID tuning constants
is used for the dilution air than those used for the enriching gas.

Section 6 – Setpoint Ramp/Soak Programming Option
6.1 Overview
What is programming?

The term “programming” is used here to identify the process for selecting
and entering the individual ramp and soak segment data needed to
generate the required setpoint versus time profile (also called a program).
A segment is a ramp or soak function which together make up a setpoint
program. Setpoint Ramp/Soak Programming lets you configure 6 ramp
and 6 soak segments to be stored for use as one program or several small
programs. You designate the beginning and end segments to determine
where the program is to start and stop.

Review program data
and configuration

While the procedure for programming is straightforward, and aided by
prompts, we suggest that you read “Program Contents” in this section as
well as “Section 3 - Configuration” before doing the setpoint
programming.

Fill out the worksheet

Draw a Ramp/Soak Profile on the worksheet provided and fill in the
information for each segment. This will give you a record of how the
program was developed.

6.2 Program Contents
What you will configure

Basically, you will configure all the data that is relevant to each ramp and
soak segment for a given setpoint versus time profile. The controller will
prompt you through the sequence of segments and associated functions.

Ramp segments

A ramp segment is the time it will take to change the setpoint to the next
setpoint value in the program.
Ramps are odd number segments. Segment #1 will be the initial ramp
time.
Ramp time is determined in either:
TIME* - Hours.Minutes
Range = 0-99hr.59 min.
or
RATE* - EU/MIN or EU/HR
Range = 0 to 999
* This selection of time or rate is made at prompt “RAMP UNIT”.

Set this prompt before entering any Ramp.
ATTENTION

Entering “0” will imply an immediate step change in
setpoint to the next soak.
Soak segments

A soak segment is a combination of soak setpoint (value) and a soak
duration (time).
Soaks are even number segments.
Segment 2 will be the initial soak value and soak time.
The soak setpoint range value must be within the setpoint high and low
range limits in engineering units.
SOAK TIME is the duration of the soak and is determined in:
TIME - Hours.Minutes
RANGE = 0-99hr.59 min.

Start segment number

This designates the number of the first segment (odd number).
Range = 1 to 11

End segment number

This designates the number of the last segment. It must be a soak segment
(even number).
Range = 2 to 12

Recycle number

This number allows the program to recycle a specified number of times
from beginning to end.
Range = 0 to 99

206

UDC 3300 Controller Product Manual

4/00

Guaranteed soak

Each soak segment can have a deviation value of from 0 to ± 99 which
guarantees the value for that segment.
Guaranteed soak segment values >0 guarantee that the segments process
variable is within the ± deviation for the configured soak time. Whenever
the ± deviation is exceeded, soak timing is frozen.
There are no guaranteed soaks whenever the deviation value is configured
to 0; i.e., soak segments start timing soak duration as soon as the soak
setpoint is first reached, regardless of where the process variable remains
relative to the soak segment.
The value is the number in engineering units, above or below the setpoint,
outside of which the timer halts. The range is 0 to 99.
The decimal location corresponds to input 1 decimal selection.

Program state

This selection determines the program state after completion.
The selections are:
DISABL = Program is disabled
HOLD = Program on hold (RUN key restarts the program.)

Program termination
state

This function determines the status of the controller upon completion.
The selections are:
LASTSP = controls to last setpoint and last control mode
F SAFE = manual mode, failsafe output
ATTENTION

If power is lost during a program, upon power-up the
controller will be in hold and the setpoint value will be the setpoint value
prior to the beginning of the setpoint program. The program is placed in
hold at the beginning of the first segment in the program.
Hot Start

4/00

This function determines whether LSP1 or PV is used as the setpoint
when the program is initially changed from HOLD to RUN.
The selections are:
DISABL = When the program is initially changed from HOLD to
RUN the present LSP1 value is captured as the default setpoint. If the
program is terminated or the power cycled before the program has
completed, the LSP1 is used as the control setpoint. The beginning
segment uses this value as the initial ramp setpoint.
ENABL = When the program is initially changed from HOLD to
RUN the present PV value is captured and used as the beginning setpoint
value for the ramp segment. If the program is terminated before
completion, the setpoint value will revert back to the PV value captured at
the initial HOLD to RUN transition. If the power is cycled before
program completion, upon power-up the setpoint is set to the PV value at
power-up and when the program is restarted that setpoint value is used
initially.

Ramp unit

This determines the engineering units for the ramp segments.
The selections are:

This selection cannot be changed while a program is in

operation.
ATTENTION

208

The Accutune TUNE selection will operate during setpoint programming.
When it is initiated during a program, it places the program into Hold
until it completes, then returns it to either Run or Hold depending what
the state was before Tuning started.

Section 7 – Input Calibration
7.1 Overview
Introduction

This section describes the field calibration procedures for Input 1 and
Input 2. Every UDC 3300 controller contains all input actuation ranges
fully factory calibrated and ready for configuration to range by the user.
However, these procedures can be implemented if the factory calibration
of the desired range is not within specifications.
Note that the field calibration will be lost if a change in input type
configuration is implemented at a later time. The original factory
calibration data remains available for later use after a field calibration is
done.

7.6 Restoring Factory Calibration
How to restore it

The factory calibration constants for all the input actuation types that can
be used with the controller are stored in its nonvolatile memory. Thus,
you can quickly restore the “Factory Calibration” for a given input
actuation type by simply changing the actuation type to another type and
then changing it back to the original type. See Table 7-6 for the procedure.

8.2 Current Proportional Output Calibration
Introduction

Calibrate the controller so that the output provides the proper amount of
current over the desired range. The controller can provide an output
current range of from 0 to 21 milliamperes and can be calibrated at 4 mA
for 0 % of output and 20 mA for 100 % of output or any other values
between 0 mA and 21 mA.

Equipment needed

You will need a standard shop type milliammeter, with whatever accuracy
is required, capable of measuring 0 to 20 milliamps.

Calibrator connections

Referring to Figure 8-1, wire the controller according to the procedure
given in Table 8-1.
Table 8-1

Set Up Wiring Procedure Current Proportional Output

Step

Figure 8-1

Action

Apply power and allow the controller to warm up 15 minutes before you

*When attempting to achieve 0 mA, always adjust the output to about 0.5 mA, and slowly decrease until the
output just goes to zero. Further decrementing will not change the output current (since the circuit cannot
produce negative current) but will affect the accuracy of the output by creating a dead zone where no
current flows.

8.3 Position Proportional and Three Position Step Output Calibration
Position proportional
control

When the UDC 3300 controller has a Position Proportional control output,
calibrate the controller so that the increase and decrease relays operate
properly with respect to the position of the external feedback slidewire.

Three position step
control

Three Position Step Control Output Models with Motor Position
Indication
(Model Numbers DC330X-EE-XXX-X2, DC330X-AA-XXX-02)
This model must have its output calibrated per the entire procedure to
ensure the displayed output (slidewire position) agrees with the final
control element position.
Three Position Step Control Output Models without Motor Position
Indication
(Model Numbers 330X-EE-XXX-X0, DC330X-AA-XXX-X0)
This model only requires that the “Motor Time” be entered as shown in
the calibration procedure. FULL CALIBRATION IS NOT REQUIRED.

Equipment needed

None

Connections

Apply power and allow the controller to warm up 30 minutes before you
calibrate. Leave all field wiring connected to the rear terminals.

Auto mode vs manual
mode

There are two ways in which to calibrate Position Proportional or 3
Position Step control:
AUTO mode or MANUAL mode.

Rules for auto mode vs
manual mode

The Auto-mode selection must be done at least once before the manual
mode will operate properly. Failure to use the Auto-mode procedure will
prevent the controller from going into automatic control mode.

Displayed values

During the Auto-mode calibration procedure, the values being displayed
are used only to indicate if the motor is still traveling. To view the actual
calibration value, use the manual mode after the Auto-mode is completed.
These values can be changed for purposes of tweaking the calibration.

236

UDC 3300 Controller Product Manual

Procedure

The procedure for calibrating the Position Proportional output and
3 Position Step control output is listed in Table 8-3. Make sure
LOCKOUT in Tuning Set Up group is set to NONE. See Section 3 –
Configuration.
For Three Position Step Control Output models without Motor Position
Indication, do steps 1 and 2 only.
For Position Proportional Output and Three Position Step Control Output
models with Motor Position Indication, follow the entire calibration
procedure.
ATTENTION

These prompts only appear when position OUT ALG is
selected. If motor position for 3PSTEP is desired, first configure unit for
“position.” After calibration the unit can be switched to 3PSTEP.

amount of current over the desired range. The controller can provide an
auxiliary output current range of from 0 to 21 milliamperes and can be
calibrated at 4 mA for 0 % of output and 20 mA for 100 % of output or
any other values between 0 mA and 21 mA.

Equipment needed

You will need a standard shop type milliammeter with whatever accuracy
is required, capable of measuring 0 to 20 milliamps.

Installation related
problems

Read the Installation section in this manual to make sure the UDC 3300
has been properly installed. The installation section provides information
on protection against electrical noise, connecting external equipment to
the controller, and shielding and routing external wiring.
ATTENTION

System noise induced into the controller will result in
diagnostic error messages recurring. If the diagnostic error messages can
be cleared, it indicates a “soft” failure and is probably noise related.
If system noise is suspected, completely isolate the controller from all
field wiring. Use calibration sources to simulate PV and check all
controller functions; i.e. Gain, Rate, Reset, Output, Alarms, etc.
Application related
problems

Review the application of the controller; then, if necessary, direct your
questions to the local sales office.

Hardware and software
related problems

Use the troubleshooting error message prompts and controller failure
symptoms to identify typical failures which may occur in the controller.
Follow the troubleshooting procedures to correct them.

Section 11 – Appendix A – Manual Tuning
11.1 Overview
Introduction

When you tune a controller, there are some things to consider:
• Process Characteristics - Gain, Time Constants, etc.
• Desired response - Minimal overshoot
Basically, controller tuning consists of determining the appropriate values
for the Gain (PB), Rate (Derivative), and Reset (Integral) time tuning
parameters (control constants) that will give the control you want.
Depending on the characteristics of the deviation of the process variable
from the setpoint, the tuning parameters interact to alter the controller’s
output and produce changes in the value of the process variable.
Since each parameter responds to a specific characteristic of the deviation,
you may not need a combination of all three. It depends on the process
characteristics and the desired control response.

Tuning technique

You can estimate a starting point and the tuning parameters required to
give the desired controller response and with some experience become
proficient with this method.
An alternate approach is to rely on a tuning technique. In practice, tuning
techniques usually do not give exactly the type of response desired; thus,
some final adjustments to the tuning parameters must be made.
However, you should at least obtain a reasonable starting point from
which the desired response characteristics can be obtained.

Controller tuning
procedures

There are three procedures for tuning the controller:
• Time, Position, or Current Proportional simplex control,
• Duplex Time or Current Proportional control,
• Two sets of tuning constants for single output operation.
The suggested procedures describe how to establish and store values of
Gain (PB), Rate, and Reset time constants for your process. You must
know the type of control and algorithm your controller has.

Tuning aids

A graphic recorder (such as Honeywell model DPR, DR4500, or VP131)
connected to the process variable will make it easier to determine when
the oscillations are constant and also the time for one oscillation. If a
recorder is not available, you can use a stopwatch to time the oscillation of
the process variable displayed on the controller.

11.2 Time, Position, or Current Proportional Simplex Control
Procedure

The procedure listed in Table 11-1 gives you the steps for manually tuning
a controller with Time, Position, or Current proportional simplex control.
Table 11-1

Manual Tuning Procedure for Simplex Control

Step

Action

In Manual Mode, adjust the output to bring the PV (Process Variable) near
the desired value.

Set the Rate time to 0 minutes and set the Reset time to the maximum value
(50.00 minutes) or set repeats/min to the minimum value to minimize reset
action
If applicable, set the CYCLE TIME to 4 seconds and DEADBAND
to 0.5.
Increase GAIN (decrease PB) significantly. Try a factor of 10.

Adjust the local setpoint to equal PV and switch to Automatic control mode.

Increase the setpoint by 5 or 10% and observe the process variable
response.

If the PV oscillates, continue to Step 7. If it does not oscillate, return to the
original setpoint and increase GAIN (decrease PB) again by a factor of 2,
and repeat Step 5.

Compare the oscillations with the figure below:

Process Variable

Pattern A

Pattern B

Pattern C

Amplitude

Time for one cycle
Time

20778

• If the oscillation matches pattern A, go to Step 8.
• If the oscillation matches pattern B, increase GAIN (decrease PB) by a
factor of 2 and repeat Steps 4 to 6.
• If the oscillation matches pattern C, decrease GAIN (increase PB) by a
factor of 0.8 and repeat Steps 4 to 6
The amplitude of the cycle is immaterial, but all of the elements of the loop
must be within the operating range (i.e., the valve must not go full open or
closed).

274

Record the current value of GAIN (or PB) and measure and record the value
of time for one completed oscillation of PV.

Select the proper set of formulas from Table 11-2. Use the values of Gain (or
PB) and time (in minutes) in the formulas to arrive at the controller’s tuning
parameters settings.

UDC 3300 Controller Product Manual

4/00

Step

Action

Enter the values of GAIN (or PB), RATE, and RESET in minutes (or repeats
per minute) into the UDC 3300 controller and verify that the PV response is
adequate.
Make additional trimming adjustments, if necessary, to fine tune the
controller per the guidelines shown below:
TO REDUCE OVERSHOOT
Less Gain (more PB) perhaps a longer Rate time.
TO INCREASE OVERSHOOT OR INCREASE SPEED OR RESPONSE
More Gain (less PB), perhaps shorter Rate time.
