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.

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.

Couple Jumper
One jumper is used for AC / DC couple. If AC couple is used, then the jumper
is removed from the board. If DC couple is used, then the jumper is installed.
Input Range Jumper
For most inputs, one jumper is used to select the input range. However, for
the following ranges, set the jumpers as stated:
5 A: Remove all jumpers from the input range.
2 V: Install one jumper in “.2/2 ” position and one jumper in “2 only”.
All Other Ranges: One jumper in the selected range only.
Do not have a jumper in both the voltage and current ranges at the same time.
Avoid placing a jumper across two ranges.
CAUTION: To maintain the electrical safety of the meter, remove
unneeded jumpers completely from the meter. Do not move the
jumpers to positions other than those specified.

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.
