GENERAL DESCRIPTION

A linear DC output signal is available as an optional Plug-in card. The card
provides either 20 mA or 10 V signals. The output can be scaled independent of
the input range and can track either the input, totalizer, max or min readings.
Once the meters have been initially configured, the parameter list may be
locked out from further modification in its entirety or only the setpoint values
can be made accessible.
The meters have been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.

The PAX® Analog Panel Meters offer many features and performance
capabilities to suit a wide range of industrial applications. Available in five
different models to handle various analog inputs, including DC Voltage/Current,
AC Voltage/Current, Process, Temperature, and Strain Gage Inputs. Refer to
pages 4 through 6 for the details on the specific models. The optional plug-in
output cards allow the opportunity to configure the meter for present
applications, while providing easy upgrades for future needs.
The meters employ a bright 0.56" LED display. The unit is available with a
red sunlight readable or a standard green LED. The intensity of display can be
adjusted from dark room applications up to sunlight readable, making it ideal
for viewing in bright light applications.
The meters provide a MAX and MIN reading memory with programmable
capture time. The capture time is used to prevent detection of false max or min
readings which may occur during start-up or unusual process events.
The signal totalizer (integrator) can be used to compute a time-input product.
This can be used to provide a readout of totalized flow, calculate service
intervals of motors or pumps, etc. The totalizer can also accumulate batch
weighing operations.
The meters have four setpoint outputs, implemented on Plug-in option cards.
The Plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or
either quad sinking or quad sourcing open collector logic outputs. The setpoint
alarms can be configured to suit a variety of control and alarm requirements.
Communication and Bus Capabilities are also available as option cards.
These include RS232, RS485, Modbus, DeviceNet, and Profibus-DP. Readout
values and setpoint alarm values can be controlled through the bus. Additionally,
the meters have a feature that allows a remote computer to directly control the
outputs of the meter. With an RS232 or RS485 card installed, it is possible to
configure the meter using a Windows® based program. The configuration data
can be saved to a file for later recall.

*After 20 min. warm-up. Accuracy is specified in two ways: Accuracy over an 18
to 28 °C and 15 to 75% RH environment; and Accuracy over a 0 to 50 °C and 0 to
85% RH (non condensing) environment. Accuracy specified over the 0 to 50 °C
operating range includes meter tempco and ice point tracking effects. The
specification includes the A/D conversion errors, linearization conformity, and
thermocouple ice point compensation. Total system accuracy is the sum of meter
and probe errors. Accuracy may be improved by field calibrating the meter readout
at the temperature of interest.
** The accuracy over the interval -270 to -200 °C is a function of temperature,
ranging from 1 °C at -200 °C and degrading to 7 °C at -270 °C. Accuracy may be
improved by field calibrating the meter readout at the temperature of interest.

UNITS LABEL KIT (PAXLBK) - Not required for PAXT

PROGRAMMING SOFTWARE

Each meter has a units indicator with backlighting that can be customized
using the Units Label Kit. The backlight is controlled in the programming.
Each PAXT meter is shipped with °F and °C overlay labels which can be
installed into the meter’s bezel display assembly.

The Crimson software is a Windows based program that allows configuration
of the PAX meter from a PC. Crimson offers standard drop-down menu
commands, that make it easy to program the meter. The meter’s program can
then be saved in a PC file for future use. A PAX serial plug-in card or PAX USB
programming card is required to program the meter using the software. Crimson
can be downloaded at www.redlion.net.

EXTERNAL CURRENT SHUNTS (APSCM)

To measure DC current signals greater than 2 ADC, a shunt must be used. The
APSCM010 current shunt converts a maximum 10 ADC signal into 100.0 mV.
The APSCM100 current shunt converts a maximum 100 ADC signal into 100.0
mV. The continuous current through the shunt is limited to 115% of the rating.

1.0 Installing

the

Meter

Installation

While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel
latch should be engaged in the farthest forward slot possible. To achieve a
proper seal, tighten the latch screws evenly until the unit is snug in the panel
(Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.

The PAX meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert the unit into the panel cutout.

Installation Environment

The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.

the

Jumpers

The meter can have up to four jumpers that must be checked and / or changed
prior to applying power. The following Jumper Selection Figures show an
enlargement of the jumper area.
To access the jumpers, remove the meter base from the case by firmly
squeezing and pulling back on the side rear finger tabs. This should lower the
latch below the case slot (which is located just in front of the finger tabs). It is
recommended to release the latch on one side, then start the other side latch.

User Input Logic Jumper

This jumper selects the logic state of all the user inputs. If the user inputs are
not used, it is not necessary to check or move this jumper.

PAXH:
Signal Jumper

Input Range Jumper

This jumper is used to select the proper input range. The input range selected
in programming must match the jumper setting. Select a range that is high enough
to accommodate the maximum input to avoid overloads. The selection is different
for each meter. See the Jumper Selection Figure for appropriate meter.

This jumper is used to select the signal type. For current signals, the jumper
is installed. For voltage signals, remove the jumper from the board. (For 2 V
inputs, this removed jumper can be used in the “2 V only” location.)

Excitation Output Jumper

This jumper is used for AC / DC couple. If AC couple, then the jumper is
removed from the board. If DC couple is used, then the jumper is installed.

Couple Jumper

If your meter has excitation, this jumper is used to select the excitation range
for the application. If excitation is not being used, it is not necessary to check or
move this jumper.

PAXD Jumper Selection
Input Range Jumper

One jumper is used for voltage/ohms or current input ranges. Select the proper input range high
enough to avoid input signal overload. Only one jumper is allowed in this area. Do not have a jumper
in both the voltage and current ranges at the same time. Avoid placing the jumper across two ranges.

3.0 Installing Plug-In Cards
To Install:

The plug-in cards are separately purchased optional cards that perform
specific functions. These cards plug into the main circuit board of the meter. The
plug-in cards have many unique functions when used with the PAX.

1. With the meter removed from the case, locate the plug-in card connector for
the card type to be installed. The types are keyed by position with different
main circuit board connector locations. When installing the card, hold the
meter by the rear terminals and not by the front display board.
If installing the Quad sourcing Plug-in Card (PAXCDS40), set the jumper for
internal or external supply operation before continuing.

CAUTION: The plug-in card and main circuit board contain static
sensitive components. Before handling the cards, discharge static
charges from your body by touching a grounded bare metal
object. Ideally, handle the cards at a static controlled clean
workstation. Also, only handle the cards by the edges. Dirt, oil or
other contaminants that may contact the cards can adversely
affect circuit operation.

2. Install the plug-in card by aligning the card terminals with the slot bay in the
rear cover. Be sure the connector is fully engaged and the tab on the plug-in
card rests in the alignment slot on the display board.
3. Slide the meter base back into the case. Be sure the rear cover latches fully
into the case.
4. Apply the plug-in card label to the bottom side of the meter in the designated
area. Do Not Cover the vents on the top surface of the meter. The surface of
the case must be clean for the label to adhere properly.

4.0 Wiring

Meter

WIRING OVERVIEW

4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:
Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)
6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide
varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor
switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid
state outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000

Varistor: ILS11500 or ILS23000
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.

Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that power supplied
to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position.
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded
wires should be tinned with solder). Insert the lead under the correct screwclamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the
unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors,
control relays, transformers, and other noisy components.

250 Vrms with respect to AC Power (meter Terminals 1 &
2). To be certain that the ratings are not exceeded, these

wiring the meter.

200mA AC MAX.

CAUTION:
1. Where possible, connect the neutral side of the signal (including current shunts) to the input common of the meter. If the input signal is sourced from
an active circuit, connect the lower impedance (usually circuit common) to the input signal common of the meter.
2. For phase-to-phase line monitoring where a neutral does not exist, or for any other signal input in which the isolation voltage rating is exceeded, an isolating potential
transformer must be used to isolate the input voltage from earth. With the transformer, the input common of the meter can then be earth referenced for safety.
3. When measuring line currents, the use of a current transformer is recommended. If using external current shunts, insert the shunt in the neutral return line. If the
isolation voltage rating is exceeded, the use of an isolating current transformer is necessary.

DEADLOAD COMPENSATION

BRIDGE COMPLETION RESISTORS

In some cases, the combined deadload and liveload output may exceed the
range of the 24 mV input. To use this range, the output of the bridge can be offset
a small amount by applying a fixed resistor across one arm of the bridge. This
shifts the electrical output of the bridge downward to within the operating range
of the meter. A 100 K ohm fixed resistor shifts the bridge output approximately
-10 mV (350 ohm bridge, 10 V excitation).
Connect the resistor between +SIG and -SIG. Use a metal film resistor with
a low temperature coefficient of resistance.

For single strain gage applications, bridge completion resistors must be
employed externally to the meter. Only use metal film resistors with a low
temperature coefficient of resistance.
Load cells and pressure transducers are normally implemented as full
resistance bridges and do not require bridge completion resistors.

STEP BY STEP PROGRAMMING INSTRUCTIONS:

DISPLAY MODE

The meter normally operates in the Display Mode. In this mode, the meter
displays can be viewed consecutively by pressing the DSP key. The annunciators
to the left of the display indicate which display is currently shown; Max Value
(MAX), Min Value (MIN), or Totalizer Value (TOT). Each of these displays can
be locked from view through programming. (See Module 3) The Input Display
Value is shown with no annunciator.

PROGRAMMING MODE ENTRY (PAR KEY)

The Programming Mode is entered by pressing the PAR key. If this mode is
not accessible, then meter programming is locked by either a security code or a
hardware lock. (See Modules 2 and 3 for programming lock-out details.)

MODULE ENTRY (ARROW & PAR KEYS)

PROGRAMMING MODE

Upon entering the Programming Mode, the display alternates between 
and the present module (initially ). The arrow keys (F1 and F2) are used
to select the desired module, which is then entered by pressing the PAR key.

Two programming modes are available.
Full Programming Mode permits all parameters to be viewed and modified.
Upon entering this mode, the front panel keys change to Programming Mode
operations. This mode should not be entered while a process is running, since
the meter functions and User Input response may not operate properly while
in Full Programming Mode.
Quick Programming Mode permits only certain parameters to be viewed and/
or modified. When entering this mode, the front panel keys change to
Programming Mode operations, and all meter functions continue to operate
properly. Quick Programming Mode is configured in Module 3. The Display
Intensity Level “” parameter is available in the Quick Programming
Mode only when the security code is non-zero. For a description, see Module
9—Factory Service Operations. Throughout this document, Programming
Mode (without Quick in front) always refers to “Full” Programming Mode.

PARAMETER (MODULE) MENU (PAR KEY)

Each module has a separate parameter menu. These menus are shown at the
start of each module description section which follows. The PAR key is pressed
to advance to a particular parameter to be changed, without changing the
programming of preceding parameters. After completing a module, the display
will return to  . From this point, programming may continue by selecting
and entering additional modules. (See MODULE ENTRY above.)

PARAMETER SELECTION ENTRY (ARROW & PAR KEYS)

For each parameter, the display alternates between the parameter and the
present selection or value for that parameter. For parameters which have a list
of selections, the arrow keys (F1 and F2) are used to sequence through the
list until the desired selection is displayed. Pressing the PAR key stores and
activates the displayed selection, and also advances the meter to the next
parameter.

PROGRAMMING TIPS

The Programming Menu is organized into nine modules (See above). These
modules group together parameters that are related in function. It is
recommended to begin programming with Module 1 and proceed through each
module in sequence. Note that Modules 6 through 8 are only accessible when
the appropriate plug-in option card is installed. If lost or confused while
programming, press the DSP key to exit programming mode and start over.
When programming is complete, it is recommended to record the meter settings
on the Parameter Value Chart and lock-out parameter programming with a User
Input or lock-out code. (See Modules 2 and 3 for lock-out details.)

NUMERICAL VALUE ENTRY (ARROW, RST & PAR KEYS)

For parameters which require a numerical value entry, the arrow keys can be
used to increment or decrement the display to the desired value. When an arrow
key is pressed and held, the display automatically scrolls up or scrolls down.
The longer the key is held, the faster the display scrolls.
The RST key can be used in combination with the arrow keys to enter large
numerical values. When the RST key is pressed along with an arrow key, the
display scrolls by 1000’s. Pressing the PAR key stores and activates the
displayed value, and also advances the meter to the next parameter.

FACTORY SETTINGS

Factory Settings may be completely restored in Module 9. This is a good
starting point if encountering programming problems. Throughout the module
description sections which follow, the factory setting for each parameter is
shown below the parameter display. In addition, all factory settings are listed on
the Parameter Value Chart following the programming section.

PROGRAMMING MODE EXIT (DSP KEY or PAR KEY at 

ALTERNATING SELECTION DISPLAY

In the module description sections which follow, the dual display with
arrows appears for each programming parameter. This is used to illustrate the
display alternating between the parameter (top display) and the parameter's
Factory Setting (bottom display). In most cases, selections or value ranges for
the parameter will be listed on the right.

The Programming Mode is exited by pressing the DSP key (from anywhere
in the Programming Mode) or the PAR key (with   displayed). This will
commit any stored parameter changes to memory and return the meter to the
Display Mode. If a parameter was just changed, the PAR key should be pressed
to store the change before pressing the DSP key. (If power loss occurs before
returning to the Display Mode, verify recent parameter changes.)

Linear - Scaling Points (2)

These bottom selections are not
available for the PAXT.

For linear processes, only 2 scaling points are necessary. It is recommended
that the 2 scaling points be at opposite ends of the input signal being applied.
The points do not have to be the signal limits. Display scaling will be linear
between and continue past the entered points up to the limits of the Input Signal
Jumper position. Each scaling point has a coordinate-pair of Input Value ()
and an associated desired Display Value ().

Rounding selections other than one, cause the Input Display to ‘round’ to the
rounding increment selected (ie. rounding of ‘5’ causes 121 to round to 120 and
124 to round to 125). Rounding starts at the least significant digit of the Input
Display. Some parameter entries (setpoint values, etc.) may be adjusted to this
display rounding selection.

Nonlinear - Scaling Points (Greater than 2)

For non-linear processes, up to 16 scaling points may be used to provide a
piece-wise linear approximation. (The greater the number of scaling points
used, the greater the conformity accuracy.) The Input Display will be linear
between scaling points that are sequential in program order. Each scaling point
has a coordinate-pair of Input Value () and an associated desired Display
Value (). Data from tables or equations, or empirical data could be used to
derive the required number of segments and data values for the coordinate pairs.
In the SFPAX software, several linearization equations are available.

The temperature display can be corrected with an offset value. This can be
used to compensate for probe errors, errors due to variances in probe placement
or adjusting the readout to a reference thermometer. This value is automatically
updated after a Zero Display to show how far the display is offset. A value of
zero will remove the affects of offset.

The digital filter will adapt to variations in the input signal. When the
variation exceeds the input filter band value, the digital filter disengages. When
the variation becomes less than the band value, the filter engages again. This
allows for a stable readout, but permits the display to settle rapidly after a large
process change. The value of the band is in display units. A band setting of ‘0’
keeps the digital filter permanently engaged.

For Key-in (), enter the known first Input Value by using the arrow keys.
The Input Range selection sets up the decimal location for the Input Value. With
0.02A Input Range, 4mA would be entered as 4.000. For Apply (), apply
the input signal to the meter, adjust the signal source externally until the desired
Input Value appears. In either method, press the PAR key to enter the value
being displayed.
Note:  style - Pressing the RST key will advance the display to the next
scaling display point without storing the input value.

For the PAXT, the following parameters only apply to Custom
Sensor Scaling.

If Input Values and corresponding Display Values are known, the Key-in
() scaling style can be used. This allows scaling without the presence or
changing of the input signal. If Input Values have to be derived from the actual
input signal source or simulator, the Apply () scaling style must be used.
After using the Apply () scaling style, this parameter will default back to
 but the scaling values will be shown from the previous applied method.

The input filter setting is a time constant expressed in tenths of a second. The
filter settles to 99% of the final display value within approximately 3 time
constants. This is an Adaptive Digital Filter which is designed to steady the
Input Display reading. A value of ‘0’ disables filtering.

Enter the first coordinating Display Value by using the arrow keys. This is

selection.

This parameter sets the slope value for ice point compensation for the
Custom TC range () only. The fixed thermocouple ranges are
automatically compensated by the meter and do not require this setting. To
calculate this slope, use µV data obtained from thermocouple manufacturers’
tables for two points between 0°C and 50°C. Place this corresponding µV and
°C information into the equation:

slope = (µV2 - µV1)/(°C2 - °C1).
Due to the nonlinear output of thermocouples, the compensation may show
a small offset error at room temperatures. This can be compensated by the offset
parameter. A value of 0 disables internal compensation when the thermocouple
is externally compensated.

maximum +20 mA can be scaled to is 32,767 with 0 mA being 0 and Display
Rounding of 1. (Decimal points are ignored.) The other half of 65,535 is for
the lower half of the range 0 to -20 mA even if it is not used. With Display
Rounding of 2, +20 mA can be scaled for 65,535 (32,767 x 2) but with even
Input Display values shown.
5. For input levels beyond the first programmed Input Value, the meter extends
the Display Value by calculating the slope from the first two coordinate pairs
( /  &  / ). If  = 4 mA and  = 0, then 0 mA
would be some negative Display Value. This could be prevented by making
 = 0 mA /  = 0,  = 4 mA /  = 0, with  = 20 mA /
 = the desired high Display Value. The calculations stop at the limits of
the Input Range Jumper position.
6. For input levels beyond the last programmed Input Value, the meter extends
the Display Value by calculating the slope from the last two sequential
coordinate pairs. If three coordinate pair scaling points were entered, then the
Display Value calculation would be between  /  &  / .
The calculations stop at the limits of the Input Range Jumper position.

Enter the second coordinating Display Value by using the arrow keys. This

General Notes on Scaling

1. Input Values for scaling points should be confined to the limits of the Input
Range Jumper position.
2. The same Input Value should not correspond to more than one Display Value.
(Example: 20 mA can not equal 0 and 10.)
This is referred to as read out jumps (vertical scaled segments).
3. The same Display Value can correspond to more than one Input Value.
(Example: 0 mA and 20 mA can equal 10.)
This is referred to as readout dead zones (horizontal scaled segments).

FUNCTION KEYS

The three user inputs are individually programmable to perform specific
meter control functions. While in the Display Mode or Program Mode, the
function is executed the instant the user input transitions to the active state.
The front panel function keys are also individually programmable to perform
specific meter control functions. While in the Display Mode, the primary
function is executed the instant the key is pressed. Holding the function key for
three seconds executes a secondary function. It is possible to program a
secondary function without a primary function.
In most cases, if more than one user input and/or function key is programmed
for the same function, the maintained (level trigger) actions will be performed
while at least one of those user inputs or function keys are activated. The
momentary (edge trigger) actions will be performed every time any of those
user inputs or function keys transition to the active state.

The Zero (Tare) Display provides a way to zero the Input Display value at
various input levels, causing future Display readings to be offset. This function
is useful in weighing applications where the container or material on the scale
should not be included in the next measurement value. When activated
(momentary action),  flashes and the Display is set to zero. At the same
time, the Display value (that was on the display before the Zero Display) is
subtracted from the Display Offset Value and is automatically stored as the new
Display Offset Value (). If another Zero (tare) Display is performed, the
display will again change to zero and the Display reading will shift accordingly.

Note: In the following explanations, not all selections are available for both

user inputs and front panel function keys. Alternating displays are shown
with each selection. Those selections showing both displays are available for
both. If a display is not shown, it is not available for that selection. 

This function will switch the Input Display between Relative and Absolute.
The Relative is a net value that includes the Display Offset Value. The Input
Display will normally show the Relative unless switched by this function.
Regardless of the display selected, all meter functions continue to operate based
on relative values. The Absolute is a gross value (based on Module 1 DSP and
INP entries) without the Display Offset Value. The Absolute display is selected
as long as the user input is activated (maintained action) or at the transition of
the function key (momentary action). When the user input is released, or the
function key is pressed again, the input display switches back to Relative
display.  (absolute) or  (relative) is momentarily displayed at transition
to indicate which display is active.

No function is performed if activated. This is the factory setting for all user

The meter can be programmed to automatically compensate for zero drift.
Drift may be caused by changes in the transducers or electronics, or
accumulation of material on weight systems.
Auto-zero tracking operates when the readout remains within the tracking
band for a period of time equal to the tracking delay time. When these
conditions are met, the meter re-zeroes the readout. After the re-zero operation,
the meter resets and continues to auto-zero track.
The auto-zero tracking band should be set large enough to track normal zero
drift, but small enough to not interfere with small process inputs. The resolution
of the band value will be affected by the input rounding factor (1-INP, round).
For filling operations, the fill rate must exceed the auto-zero tracking rate.
This avoids false tracking at the start of the filling operation.

Auto-zero tracking is disabled and internally reset by setting the auto-zero



The Totalizer Time Base and scale factor are overridden when a user input or
function key is programmed for store batch (). In this mode, when the user
input or function key is activated, the Input Display reading is one time added
to the Totalizer (batch). The Totalizer retains a running sum of each batch
operation until the Totalizer is reset. This is useful in weighing operations, when
the value to be added is not based on time but after a filling event.

TOTALIZER USING TIME BASE
Totalizer accumulates as defined by:

TOTALIZER TIME BASE

Totalizer Scale Factor - 0.001 to 65.000

This is the time base used in Totalizer accumulations. If the Totalizer is being
accumulated through a user input programmed for Batch, then this parameter
does not apply.

 to 

For most applications, the Totalizer reflects the same decimal point location
and engineering units as the Input Display. In these cases, the Totalizer Scale
Factor is 1.000. The Totalizer Scale Factor can be used to scale the Totalizer to
a different value than the Input Display. Common possibilities are:
1. Changing decimal point location (example tenths to whole)
2. Average over a controlled time frame.
Details on calculating the scale factor are shown later.
If the Totalizer is being accumulated through a user input programmed for
Batch, then this parameter does not apply.

10.0 x 1.000 = 0.1667 gallon accumulates each second

This results in:
10.0 gallons accumulates each minute
600.0 gallons accumulates each hour

TOTALIZER SCALE FACTOR CALCULATION EXAMPLES

1. When changing the Totalizer Decimal Point () location from the
Input Display Decimal Point (), the required Totalizer Scale Factor is
multiplied by a power of ten.
Example:
Input () = 0
Input () = 0.0 Input () = 0.00

Example: Average temperature per hour in a 4 hour period, the scale factor
would be 0.250. To achieve a controlled time frame, connect an external timer
to a user input programmed for . The timer will control the start (reset)
and the stopping (hold) of the totalizer.

Example: The input reading is at a constant rate of 10.0 gallons per minute. The

 = Latch with immediate reset action; This action latches the alarm
output on at the trigger point per the Setpoint Action shown in Setpoint Alarm
Figures. Latch means that the alarm output can only be turned off by front
panel function key or user input manual reset, serial reset command or meter
power cycle. When the user input or function key is activated (momentary or
maintained), the corresponding “on” alarm output is reset immediately and
remains off until the trigger point is crossed again. (Previously latched alarms
will be off if power up Display Value is lower than setpoint value.)
 = Latch with delay reset action; This action latches the alarm output
on at the trigger point per the Setpoint Action shown in Setpoint Alarm
Figures. Latch means that the alarm output can only be turned off by front
panel function key or user input manual reset, serial reset command or meter
power cycle. When the user input or function key is activated (momentary or
maintained), the meter delays the event until the corresponding “on” alarm
output crosses the trigger off point. (Previously latched alarms are off if
power up Display Value is lower than setpoint value. During a power cycle,
the meter erases a previous Latch 2 reset if it is not activated at power up.)

Set the parity bit to match that of the other serial communications equipment
used. The meter ignores the parity when receiving data, and sets the parity bit
for outgoing data. If no parity is selected with 7-bit word length the meter
transmits and receives data with 2 stop bits. (For example: 10 bit frame with
mark parity)

Set the baud rate to match that of other serial communications equipment.
Normally, the baud rate is set to the highest value that all of the serial
communications equipment is capable of transmitting.

Sending Numeric Data

Numeric data sent to the meter must be limited to 5 digits (-19,999 to 99,999).
If more than 5 digits are sent, the meter accepts the last 5. Leading zeros are
ignored. Negative numbers must have a minus sign. The meter ignores any
decimal point and conforms the number to the scaled resolution. (For example:
the meter’s scaled decimal point position = 0.0 and 25 is written to a register.
The value of the register is now 2.5 In this case, write a value = 25.0).
Note: Since the meter does not issue a reply to value change commands, follow
with a transmit value command for readback verification.

Receiving Data

Data is transmitted by the meter in response to either a transmit command (T),
a print block command (P) or User Function print request. The response from
the meter is either a full field transmission or an abbreviated transmission. In this
case, the response contains only the numeric field. The meter response mode is
established in programming.

Initiates a block print output. Registers are
defined in programming.

Command String Construction

The command string must be constructed in a specific sequence. The meter
does not respond with an error message to illegal commands. The following
procedure details construction of a command string:

7-18
19
20
21
22
23

1. The first 2 or 3 characters consist of the Node Address Specifier (N) followed
by a 1 or 2 character node address number. The node address number of the
meter is programmable. If the node address is 0, this command and the node
address itself may be omitted. This is the only command that may be used in
conjunction with other commands.
2. After the optional address specifier, the next character is the command character.
3. The next character is the register ID. This identifies the register that the
command affects. The P command does not require a register ID character. It
prints according to the selections made in print options.
4. If constructing a value change command (writing data), the numeric data is
sent next.
5. All command strings must be terminated with the string termination
characters * or $. The meter does not begin processing the command string
until this character is received. See timing diagram figure for differences of
* and $ terminating characters.

Description

2 byte Node Address field [00-99]
(Space)
3 byte Register Mnemonic field
12 byte data field; 10 bytes for number, one byte for sign, one byte
for decimal point (The T command may be a different byte length)
carriage return
line feed
* (Space)
* carriage return
* line feed

* These characters only appear in the last line of a block print.
The first two characters transmitted are the node address, unless the node address
assigned =0, in which case spaces are substituted. A space follows the node address
field. The next three characters are the register ID (Serial Mnemonic).
The numeric data is transmitted next. The numeric field is 12 characters long
(to accommodate the 10 digit totalizer), with the decimal point position floating
within the data field. Negative value have a leading minus sign. The data field
is right justified with leading spaces.
The end of the response string is terminated with a carriage return and
. When block print is finished, an extra is used to
provide separation between the blocks.

SERIAL COMMANDS FOR PAX SOFTWARE
(CSR) Control Status Register

Examples:

The Control Status Register is used to both directly control the meter’s
outputs (setpoints and analog output), and interrogate the state of the setpoint
outputs. The register is bit mapped with each bit position within the register
assigned to a particular control function. The control function are invoked by
writing to each bit position. The bit position definitions are:

1. Set manual mode, turn all setpoints off:
7 6 5 4 3 2 1 0:bit location
VJ<30>* or VJ0*

ASCII 0 = 0 0 1 1 0 0 0 0 or <30>

V is command write, J is CSR and * is terminator.

bit 0: Setpoint 1 Output Status
0 = output off
1 = output on
bit 1: Setpoint 2 Output Status
0 = output off
1 = output on
bit 2: Setpoint 3 Output Status
0 = output off
1 = output on
bit 3: Setpoint 4 Output Status
0 = output off
1 = output on
bit 4: Manual Mode
0 = automatic mode
1 = manual mode
bit 5: Always stays 0, even if 1 is sent.
bit 6: Sensor Status (PAXT only)
0 = sensor normal
1 = sensor fail
bit 7: Always stays 0, even if 1 is sent.

2. Turn SP1, SP3 outputs on and SP2, SP4 outputs off:
7 6 5 4 3 2 1 0:bit location
VJ<35>* or VJ5*

ASCII 5 = 0 0 1 1 0 1 0 1 or <35>

3. Select Automatic mode:
7 6 5 4 3 2 1 0:bit location
VJ<40>* or VJ@*

ASCII @ = 0 1 0 0 0 0 0 0 or <40>

Note: Avoid writing values <0A> (LF), <0D> (CR), <24> ($) and <2E> (*)
to the CSR. These values are interpreted by the meter as end of command
control codes and will prematurely end the write operation.

(AOR) Analog Output Register

The Analog Output Register controls the analog output of the meter. The
manual mode must first be engaged by setting bit 4 of the Control Status
Register. The range of values of this register is 0 to 4095, which corresponds to
0 mA, 0 V and 20 mA, 10 V; respectively. The table lists correspondence of the
output signal with the register value.
Register Value

Although the register is bit mapped starting with bit 7, HEX < > characters
are sent in the command string. Bits 7 and 5 always stay a zero, even if a “1” is
sent. This allows ASCII characters to be used with terminals that may not have
extended character capabilities.
Writing a “1” to bit 4 of CSR selects manual mode. In this mode, the setpoint
outputs are defined by the values written to the bits b0, b1, b2, b3; and the
analog output is defined by the value written to the AOR. Internal control of
these outputs is then overridden.
In automatic mode, the setpoint outputs can only be reset off. Writing to the
setpoint output bits of the CSR has the same effect as a Reset command (R). The
contents of the CSR may be read to interrogate the state of the setpoint outputs
and to check the status of the temperature sensor (PAXT only).

*Due to the absolute accuracy
rating and resolution of the output
card, the actual output signal may
differ 0.15% FS from the table
values. The output signal
corresponds to the range selected
(20 mA or 10 V).

Writing to this register while the meter is in the manual mode causes the
output signal to update immediately. While in the automatic mode, this register
may be written to, but the output will not update until the meter is placed in
manual mode.

Examples:

1. Set output to full scale:
VI4095*
2. Set output to zero scale:
VI0*

Command Response Time

Communication Format

Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character.
The voltage level conventions depend on the interface standard. The table
lists the voltage levels for each standard.

The meter can only receive data or transmit data at any one time (half-duplex
operation). The meter ignores commands while transmitting data, but instead
uses RXD as a busy signal. When sending commands and data to the meter, a
delay must be imposed before sending another command. This allows enough
time for the meter to process the command and prepare for the next command.

* Voltage levels at the Receiver

Data is transmitted one byte at a time with a variable idle period between
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional error detection parity bit and one or more ending stop bits. The data
format and baud rate must match that of other equipment in order for
communication to take place. The figures list the data formats employed by
the meter.

RESPONSE FROM METER

Start bit and Data bits

Reply
Transmission
Time

Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted. Since the sending and receiving devices operate at the same
transmission speed (baud rate), the data is read without timing errors.

Timing Diagram Figure
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (*) is received by the meter. The time duration of t1 is
dependent on the number of characters and baud rate of the channel.

Parity bit

After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The PAX meter ignores the parity bit of incoming data and
sets the parity bit to odd, even or none (mark parity) for outgoing data.

t1 = (10 * # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time
interval t2 varies from 2 msec to 50 msec. If no response from the meter is
expected, the meter is ready to accept another command.
If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The standard command line terminating
character is ‘*’. This terminating character results in a response time window of
50 msec minimum and 100 msec maximum. This allows sufficient time for the
release of the sending driver on the RS485 bus. Terminating the command line
with ‘$’ results in a response time window (t2) of 2 msec minimum and 50 msec
maximum. The faster response time of this terminating character requires that
sending drivers release within 2 msec after the terminating character is received.
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. t3 = (10 * # of characters) /
baud rate. At the end of t3, the meter is ready to receive the next command.
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.

Stop bit

The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit.

indicating incorrectly or inaccurately, refer to
Troubleshooting before attempting to calibrate the meter.
When recalibration is required (generally every 2 years), it should only be
performed by qualified technicians using appropriate equipment. Calibration
does not change any user programmed parameters. However, it may affect the
accuracy of the input signal values previously stored using the Apply ()
Scaling Style.
Calibration may be aborted by disconnecting power to the meter before
exiting Module 9. In this case, the existing calibration settings remain in effect.

Before starting, verify that the precision signal source is connected to the
correct terminals and ready. Allow a 30 minute warm-up period before
calibrating the meter.  and PAR can be chosen to exit the calibration mode
without any changes taking place.
Then perform the following procedure:
1. Use the arrow keys to display   and press PAR.
2. Choose the range to be calibrated by using the arrow keys and press PAR.
( and PAR can be chosen to exit the calibration mode without any changes
taking place.)
3. When the zero range limit appears on the display, apply the appropriate:
- Voltage range: dead short applied

17. Remove the meter power and remove the short from terminals 4 and 6.
18. Restore the original jumper and configuration settings.

THERMOCOUPLE Range Calibration

1. Use the arrow keys to display   and press PAR. Then choose  and
press PAR.
2. At  , apply a dead short or set calibrator to zero to input terminals 4 and
5. Wait 10 seconds, then press PAR.
3. At  , apply 50.000 mV input signal (with an accuracy of 0.01% or
better) to input terminals 4 and 5. Wait 10 seconds, then press PAR.
4. Return to the Display Mode.
5. Continue with Ice Point Calibration.

ICE POINT Calibration

1. Remove all option cards or invalid results will occur.
2. The ambient temperature must be within 20°C to 30°C.
3. Connect a thermocouple (types T, E, J, K, or N only) with an accuracy of 1°C
or better to the meter.
4. Verify the readout Display Offset is 0, Temperature Scale is °C, Display
Resolution is 0.0, and the Input Range is set for the connected thermocouple.
5. Place the thermocouple in close thermal contact to a reference thermometer
probe. (Use a reference thermometer with an accuracy of 0.25°C or better.)
The two probes should be shielded from air movement and allowed sufficient
time to equalize in temperature. (A calibration bath could be used in place of
the thermometer.)
6. In the Normal Display mode, compare the readouts.
7. If a difference exists then continue with the calibration.
8. Enter Module 9, use the arrow keys to display   and press PAR. Then
choose  and press PAR.
9. Calculate a new Ice Point value using: existing Ice Point value + (reference
temperature - Display Mode reading). All values are based on °C.
10. Enter the new Ice Point value.
11. Return to the Display Mode and verify the input reading (with 0 Display
Offset) is correct. If not correct repeat steps 8 through 10.

PAXS - Input Calibration
WARNING: Calibration of this meter requires a signal source with an
accuracy of 0.01% or better and an external meter with an accuracy
of 0.005% or better.
Before starting, connect -SIG (terminal 4) to COMM (terminal 5).
This allows a single ended signal to be used for calibration. Connect the
calibration signal to +SIG (terminal 3) and -SIG (terminal 4). Verify the Input
Range jumper is in the desired position. Allow a 30 minute warm-up period
before calibrating the meter.  and PAR can be chosen to exit the calibration
mode without any changes taking place. Perform the following procedure:
1. Press the arrow keys to display   and press PAR.
2. Choose the range to be calibrated by using the arrow keys and press PAR.
3. When the zero range limit appears on the display, apply 0 mV between +SIG
and -SIG.
4. Press PAR and ---- will appear, wait for next prompt.
5. When the top range limit appears on the display, apply the corresponding
+SIG and -SIG voltage (20 mV or 200 mV).
6. Press PAR and ---- will appear, on the display for about 10 seconds.
7. When  appears, press PAR twice to exit programming.
8. Repeat the above procedure for each range to be calibrated or to recalibrate
the same range. It is only necessary to calibrate the input ranges being used.
9. When all desired calibrations are completed, remove -SIG to COMM
connection and external signal source.
10. Restore original configuration and jumper settings.

ANALOG OUTPUT CARD CALIBRATION

Before starting, verify that the precision voltmeter (voltage output) or current
meter (current output) is connected and ready. Perform the following procedure:
1. Use the arrow keys to display   and press PAR.
2. Use the arrow keys to choose  and press PAR.
3. Using the chart below, step through the five selections to be calibrated. At
each prompt, use the PAX arrow keys to adjust the external meter display to
match the selection being calibrated. When the external reading matches, or
if this range is not being calibrated, press PAR.

PAXT - Input Calibration

Before selecting any of the calibration procedures, the input to the meter
must be at 0 mV or 0 ohms. Set the digital filer in Module 1 to 1 second. Allow
a 30 minute warm-up period before calibrating the meter. The  and PAR can
be chosen to exit calibration mode without any changes taking place.

10 OHM RTD Range Calibration

1. Set the Input Range Jumper to 10 ohm.
2. Use the arrow keys to display   and press PAR. Then choose 
and press PAR.
3. At  , apply a direct short to input terminals 3, 4 and 5 using a three wire
link. Wait 10 seconds, then press PAR.
4. At  , apply a precision resistance of 15 ohms (with an accuracy of 0.01%
or better) using a three wire link, to input terminals 3, 4 and 5. Wait 10
seconds, then press PAR.
5. Connect the RTD, return to the Display Mode and verify the input reading
(with 0 Display Offset) is correct. If not correct repeat calibration.
