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
p
ages 4 through 6 fo
r
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), o
r
either quad sinking or quad sourcing open collector logic outputs. The setpoin
t
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. Readou
t
values and setpoint alarm values can be controlled through the bus.
Additionally, the meters have a feature that allows a remote computer to directl
y
control the outputs of the meter. With an RS232 or RS485 card installed, it is
p
ossible to configure the meter using a Windows®based program.
The configuration data can be saved to a file for later recall.
DIMENSIONS In inches (mm) Note: Recommended minimum clearance (behind the panel) for mounting clip installation
is 2.1" (53.4) H x 5.0" (127) W.
A linear DC output signal is available as an optional Plug-in card. The card
p
rovides either 20 mA or 10 V signals. The output can be scaled independent o
f
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
p
revent damage to either the instrument or equipment connected to it. I
f
equipment is used in a manner not specified by the manufacturer, the protection
p
rovided 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 o
r
equipment in the event of a fault to the unit.

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.
PANEL CUT-OUT
1.0 INSTALLING THE METER
2.0 SETTING 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.
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
inputs, this removed jumper can be used in the “2 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.

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 this meter is designed with a high degree of immunity to Electro-
Magnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, its source or the method of coupling into the unit may be different for
various installations.Listed below are some EMC guidelines for successful
installation in an industrial environment.
1. The meter should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. With use of the lower input ranges or signal sources with high source
impedance, the use of shielded cable may be necessary. This helps to guard
against stray AC pick-up. Attach the shield to the input common of the meter.
Line voltage monitoring and 5A CT applications do not usually require
shielding.
3. To minimize potential noise problems, power the meter from the same power
branch, or at least the same phase voltage as that of the signal source.
4. 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 in 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.
5. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
6. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional
protection. Install line filters on the power input cable to the unit to suppress
power line interference. Install them near the power entry point of the
enclosure. The following EMI suppression devices (or equivalent) are
recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1 R3
Note: Reference manufacturer’s instructions when installing a line filter.
7. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
8. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC#SNUB0000.

6-Wire Bridge Input
DEADLOAD COMPENSATION
In some cases, the combined deadload and liveload output may exceed the
range of the 24 m 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 m (350 ohm bridge, 10 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.

2. For phase-to-phase line monitoring where a neutral does not exist, or for an 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 safet .

OVERVIEW
PROGRAMMING MENU
.0 PROGRAMMING THE METER
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 alue (MAX), Min alue (MIN), or Totalizer alue (TOT). Each of these
displays can be locked from view through programming. (See Module 3) The
Input Display alue is shown with no annunciator.
PROGRAMMING MODE
Two programming modes are available.
Full Pr gramming M de 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 Pr gramming M de 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 alue 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 alue 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.

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.)

This parameter sets the slope value for ice point compensation for the

automatically compensated by the meter and do not require this setting. To
calculate this slope, use µ data obtained from thermocouple manufacturers’
tables for two points between 0°C and 50°C. Place this corresponding µ and
°C information into the equation:
slope = (µ2- µ1)/(°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

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 alue ()
and an associated desired Display alue ().
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 alue () and an associated desired Display
alue (). 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.

General Notes on Scaling
1. Input alues for scaling points should be confined to the limits of the Input
Range Jumper position.
2. The same Input alue should not correspond to more than one Display alue.
(Example: 20 mA can not equal 0 and 10.)
This is referred to as read out jumps (vertical scaled segments).
3. The same Display alue can correspond to more than one Input alue.
(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 alue 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 alue, the meter extends
the Display alue by calculating the slope from the first two coordinate pairs
( /  &  / ). If  = 4 mA and  = 0, then 0 mA
would be some negative Display alue. This could be prevented by making
 = 0 mA /  = 0,  = 4 mA /  = 0, with  = 20 mA /
 = the desired high Display alue. The calculations stop at the limits of
the Input Range Jumper position.
6. For input levels beyond the last programmed Input alue, the meter extends
the Display alue by calculating the slope from the last two sequential
coordinate pairs. If three coordinate pair scaling points were entered, then the
Display alue calculation would be between  /  &  / .
The calculations stop at the limits of the Input Range Jumper position.
Enter the second coordinating Display alue by using the arrow keys. This
is the same for  and  scaling styles. (Follow the same procedure if
using more than 2 scaling points.)
.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 ke s. Alternating displa s are shown
with each selection. Those selections showing both displa s are available for
both. If a displa is not shown, it is not available for that selection. 

, the display will not be shown when the DSP key is pressed regardless of
Program Lock-out status. It is suggested to lock-out the display if it is not needed.
The associated function will continue to operate even if its display is locked-out.

Module 3 is the programming for Display lock-out and “Full” and “Quick”
Program lock-out.
When in the Display Mode, the available displays can be read consecutively
by repeatedly pressing the DSP key. An annunciator indicates the display being
shown. These displays can be locked from being visible. It is recommended that
the display be set to  when the corresponding function is not used.
“Full” Programming Mode permits all parameters to be viewed and
modified. This Programming Mode can be locked with a security code and/or
user input. When locked and the PAR key is pressed, the meter enters a Quick
Programming Mode. In this mode, the setpoint values can still be read and/or
changed per the selections below. The Display Intensity Level ()
parameter also appears whenever Quick Programming Mode is enabled and the
security code is greater than zero.

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.

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 alue 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 alue after each Zero Display. The Display Offset alue can be directly
keyed-in to intentionally add or remove display offset. See Relative / Absolute
Display and Zero Display explanations in Module 2.

PAXS: AUTO-ZERO BAND
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.
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 by setting the tracking band 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.
