GENERAL DESCRIPTION
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.
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.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in this
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the unit.

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.

Each PAXT meter is shipped with °F and °C overlay labels which can be
installed into the meter’s bezel display assembly.
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.
PROGRAMMING SOFTWARE
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.

Installation
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.
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.
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 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.
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.
Excitation Output 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.
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
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.)
Couple 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.

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.
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.
To Install:
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.
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.

WIRING OVERVIEW
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 screw-
clamp 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.
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.

DEADLOAD COMPENSATION
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.
BRIDGE COMPLETION RESISTORS
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.
Before connecting signal wires, the Input Range Jumper should be verified for proper position.

CAUTION: Sensor input common is NOT isolated
from user input common. In order to preserve the
safety of the meter application, the sensor input
common must be suitably isolated from hazardous
live earth referenced voltages; or input common
must be at protective earth ground potential. If not,
hazardous live voltage may be present at the User
Inputs and User Input Common terminals.
Appropriate considerations must then be given to
the potential of the user input common with respect
to earth common; and the common of the isolated
plug-in cards with respect to input common.
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.

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
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.
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.)
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.
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.

STEP BY STEP PROGRAMMING INSTRUCTIONS:
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)
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.
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.
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.
PROGRAMMING MODE EXIT (DSP KEY or PAR KEY at )
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.)

DISPLAY ROUNDING*
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.
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.
to
FILTER SETTING*
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.
to seconds
FILTER BAND*
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.
to display units
* Factory Setting can be used without affecting basic start-up.
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.
to µV/°C
For the PAXT, the following parameters only apply to Custom
Sensor Scaling.
SCALING POINTS*
Linear - Scaling Points (2)
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 ().
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.
to
SCALING STYLE
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.
This parameter does not apply for the PAXT. Scaling values for the
PAXT must be keyed-in.
INPUT VALUE FOR SCALING POINT 1
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.

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).
4. The maximum scaled Display Value spread between range maximum and
minimum is limited to 65,535. For example using +20 mA range the
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
is the same for and scaling styles. (Follow the same procedure if
using more than 2 scaling points.)

FUNCTION KEYSUSER INPUTS
6.2 mOdUle 2 - User inpUT and frOnT panel fUnCTiOn Key
parameTers ()
PARAMETER MENU
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.
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.
will represent all three user inputs. will represent all five function keys.
NO FUNCTION
No function is performed if activated. This is the factory setting for all user
inputs and function keys. No function can be selected without affecting basic
start-up.
PROGRAMMING MODE LOCK-OUT
Programming Mode is locked-out, as long as activated
(maintained action). A security code can be configured to
allow programming access during lock-out.
ZERO (TARE) DISPLAY
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.
RELATIVE/ABSOLUTE DISPLAY
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.
1919
HOLD DISPLAY
The shown display is held but all other meter functions
continue as long as activated (maintained action).
HOLD ALL FUNCTIONS
The meter disables processing the input, holds all display
contents, and locks the state of all outputs as long as activated
(maintained action). The serial port continues data transfer.
SYNCHRONIZE METER READING
The meter suspends all functions as long as activated
(maintained action). When the user input is released, the
meter synchronizes the restart of the A/D with other
processes or timing events.
STORE BATCH READING IN TOTALIZER
The Input Display value is one time added (batched) to the Totalizer at
transition to activate (momentary action). The Totalizer retains a running sum of
each batch operation until the Totalizer is reset. When this function is selected,
the normal operation of the Totalizer is overridden.
SELECT TOTALIZER DISPLAY
The Totalizer display is selected as long as activated
(maintained action). When the user input is released, the
Input Display is returned. The DSP key overrides the active
user input. The Totalizer continues to function including
associated outputs independent of being displayed.
RESET TOTALIZER
When activated (momentary action), flashes and the Totalizer resets to
zero. The Totalizer then continues to operate as it is configured. This selection
functions independent of the selected display.
RESET AND ENABLE TOTALIZER
When activated (momentary action), flashes and
the Totalizer resets to zero. The Totalizer continues to
operate while active (maintained action). When the user
input is released, the Totalizer stops and holds its value. This
selection functions independent of the selected display.
ENABLE TOTALIZER
The Totalizer continues to operate as long as activated
(maintained action). When the user input is released, the
Totalizer stops and holds its value. This selection functions
independent of the selected display.
SELECT MAXIMUM DISPLAY
The Maximum display is selected as long as activated
(maintained action). When the user input is released, the
Input Display returns. The DSP key overrides the active
user input. The Maximum continues to function independent
of being displayed.
RESET MAXIMUM
When activated (momentary action), flashes and
the Maximum resets to the present Input Display value. The
Maximum function then continues from that value. This
selection functions independent of the selected display.
RESET, SELECT, ENABLE MAXIMUM DISPLAY
When activated (momentary action), the Maximum value
is set to the present Input Display value. Maximum continues
from that value while active (maintained action). When the
user input is released, Maximum detection stops and holds its
SELECT MINIMUM DISPLAY
The Minimum display is selected as long as activated
(maintained action). When the user input is released, the
Input Display is returned. The DSP key overrides the active
user input. The Minimum continues to function independent
of being displayed.
RESET MINIMUM
When activated (momentary action), flashes and
the Minimum reading is set to the present Input Display
value. The Minimum function then continues from that value.
This selection functions independent of the selected display.
RESET, SELECT, ENABLE MINIMUM DISPLAY
When activated (momentary action), the Minimum value
is set to the present Input Display value. Minimum continues
from that value while active (maintained action). When the
user input is released, Minimum detection stops and holds
RESET MAXIMUM AND MINIMUM
When activated (momentary action), flashes and the Maximum and
Minimum readings are set to the present Input Display value. The Maximum and
Minimum function then continues from that value. This selection functions
independent of the selected display.
CHANGE DISPLAY INTENSITY LEVEL
When activated (momentary action), the display intensity changes to the next
intensity level (of 4). The four levels correspond to Display Intensity Level
() settings of 0, 3, 8, and 15. The intensity level, when changed via the
User Input/ Function Key, is not retained at power-down, unless Quick
Programming or Full Programming mode is entered and exited. The meter will

When the Input Display is above the present MAX value for the entered
delay time, the meter will capture that display value as the new MAX reading.
A delay time helps to avoid false captures of sudden short spikes.
MIN CAPTURE DELAY TIME*
When the Input Display is below the present MIN value for the entered delay
time, the meter will capture that display value as the new MIN reading. A delay
time helps to avoid false captures of sudden short spikes.
UNITS LABEL BACKLIGHT*
The Units Label Kit Accessory contains a sheet of custom unit overlays
which can be installed in to the meter’s bezel display assembly. The backlight
for these custom units is activated by this parameter.
DISPLAY OFFSET VALUE*
Unless a Zero Display was performed or an offset from Module 1 scaling is
desired, this parameter can be skipped. The Display Offset Value is the
difference from the Absolute (gross) Display value to the Relative (net) Display
value for the same input level. The meter will automatically update this Display
Offset Value after each Zero Display. The Display Offset Value can be directly
keyed-in to intentionally add or remove display offset. See Relative / Absolute
Display and Zero Display explanations in Module 2.
DISPLAY UPDATE RATE*
This parameter determines the rate of display update. When set to 20
updates/second, the internal re-zero compensation is disabled, allowing for the
fastest possible output response.

to
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.
Fill Rate ≥ tracking band
tracking time
Auto-zero tracking is disabled and internally reset by setting the auto-zero
tracking parameter = 0.
PAXT: ICE POINT COMPENSATION*
This parameter turns the internal ice point compensation on or off. Normally,
the ice point compensation is on. If using external compensation, set this
parameter to off. In this case, use copper leads from the external compensation
point to the meter. If using Custom TC range, the ice point compensation can
be adjusted by a value in Module 1 when this is yes.
This parameter does not apply for the PAXT.

TOTALIZER DECIMAL POINT*
For most applications, this matches the Input Display Decimal Point
(). If a different location is desired, refer to Totalizer Scale Factor.
TOTALIZER TIME BASE
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.
TOTALIZER SCALE FACTOR*
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.
TOTALIZER LOW CUT VALUE*
to
to
A low cut value disables Totalizer when the Input Display value falls below
the value programmed.
The resolution of this parameter will be affected by the input rounding factor
(1-INP, round).
TOTALIZER POWER UP RESET*
Reset buffer
Do not reset buffer
The Totalizer can be reset to zero on each meter power-up by setting this
parameter to reset.
- seconds (÷ 1)
TOTALIZER HIGH ORDER DISPLAY
When the total exceeds 5 digits, the front panel annunciator TOT flashes. In
this case, the meter continues to totalize up to a 9 digit value. The high order 4
digits and the low order 5 digits of the total are displayed alternately. The letter
“” denotes the high order display. When the total exceeds a 9 digit value, the
Totalizer will show “E . . .” and will stop.
TOTALIZER BATCHING
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:
Input Display x Totalizer Scale Factor
Totalizer Time Base
Where:
Input Display - the present input reading
Totalizer Scale Factor - 0.001 to 65.000
Totalizer Time Base - (the division factor of )
Example: The input reading is at a constant rate of 10.0 gallons per minute. The
Totalizer is used to determine how many gallons in tenths has flowed.
Because the Input Display and Totalizer are both in tenths of gallons, the
Totalizer Scale Factor is 1. With gallons per minute, the Totalizer Time Base
is minutes (60). By placing these values in the equation, the Totalizer will
accumulate every second as follows:
10.0 x 1.000 = 0.1667 gallon accumulates each second
60
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
(x = Totalizer display is round by tens or hundreds)
2. To obtain an average reading within a controlled time frame, the selected
Totalizer Time Base is divided by the given time period expressed in the same
timing units.
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.
- days (÷ 86400) - minutes (÷ 60)
- hours (÷ 3600)
The totalizer accumulates (integrates) the Input Display value using one of
two modes. The first is using a time base. This can be used to compute a time-
temperature product. The second is through a user input or function key
programmed for Batch (one time add on demand). This can be used to provide
a readout of temperature integration, useful in curing and sterilization
applications. If the Totalizer is not needed, its display can be locked-out and this
module can be skipped during programming.

usually unbalanced hysteresis is used. For unbalanced hysteresis modes, the
hysteresis functions on the low side for high acting setpoints and functions on
the high side for low acting setpoints.
Note: Hysteresis eliminates output chatter at the switch point, while time delay
can be used to prevent false triggering during process transient events.

= Automatic action; This action allows the alarm output to automatically
reset off at the trigger points per the Setpoint Action shown in Setpoint Alarm
Figures. The “on” alarm may be manually reset (off) immediately by a front
panel function key or user input.The alarm remains reset off until the trigger
point is crossed again.
= 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.)
* Deviation and band action setpoints are relative to the value of setpoint 1.
It is not possible to configure setpoint 1 as deviation or band actions. It is
possible to use setpoint 1 for an absolute action, while its value is being used
for deviation or band.

BAUD RATE
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.
Select either 7 or 8 bit data word lengths. Set the word length to match that
of other serial communication equipment. Since the meter receives and
transmits 7-bit ASCII encoded data, 7 bit word length is sufficient to request
and receive data from the meter.
Ñ - A communication card must be installed in order to access this module.
PARITY BIT
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)
METER ADDRESS
to
Enter the serial node address. With a single unit on a bus, an address is not
needed and a value of zero can be used (RS232 applications). Otherwise, with
multiple bussed units, a unique address number must be assigned to each meter.
The node address applies specifically to RS485 applications.

Sending Commands and Data
When sending commands to the meter, a string containing at least one
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by a the command terminator character * or $.
Command Chart
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:
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.

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.

(CSR) Control Status Register
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:
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).
Examples:
1. Set manual mode, turn all setpoints off:
V is command write, J is CSR and * is terminator.
2. Turn SP1, SP3 outputs on and SP2, SP4 outputs off:
3. Select Automatic mode:
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.
*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*
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

Command Response Time
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.
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.
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.
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.
LOGIC INTERFACE STATE RS232* RS485*
1mark (idle) TXD,RXD; -3 to -15 V a-b < -200 mV
0space (active) TXD,RXD; +3 to +15 V a-b > +200 mV
* 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.
Start bit and Data bits
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.
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.
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.

PARAMETER MENU
Enter the desired Display Intensity Level (0-15) by
using the arrow keys. The display will actively dim or
brighten as the levels are changed. This parameter also
appears in Quick Programming Mode when enabled.
DISPLAY INTENSITY LEVEL
The meter has been fully calibrated at the factory.
Scaling to convert the input signal to a desired display
value is performed in Module 1. If the meter appears to be
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.
CALIBRATION
Before starting, verify that the Input Ranger Jumper is set for the range to be
calibrated. Also verify that the precision signal source is connected 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.
