1.0 INSTALLING THE METER
Installation
The PAX Lite 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 [79Ncm]). 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.

3.0 WIRING THE METER
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 the 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.)
EMC INSTALLATION GUIDELINES
Although this meter is 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 the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
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. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail 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 only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the meter and leave the other end of the
shield unconnected and insulated from earth ground.
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 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.
4. Signal or Control cables within an enclosure should be routed as far as possible
from contactors, control relays, transformers, and other noisy components.
5. 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 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.

3.2 CONTROL INPUT WIRING
The PAXLC provides a number of control inputs, including Store, Reset,
Inhibit and Up/Down control. These inputs are active low (connected to
common), so the external switching device should be connected between the
control input and common terminals.
Up/Down - This input determines the direction of the count. Unconnected,
the meter will count up. When input is pulled low, the meter will count down.
Reset - When this input is pulled low , the meter will reset to zero. If the input
remains low or connected to common, the meter will be held in the reset mode,
and not able to count.
Inhibit - When low, this input will prevent the meter from counting. If the
input remains low or connected to the common, the meter will not be able to
count.
Store - A low will stop the display from updating. It will freeze the display
as long as the input is held low. Once released the display will update to the
current count display.

5.0 SCALING THE METER
In many industrial applications, a meter is required to totalize the output of an
operation or event. The pulses from a sensor are received by the PAXLC, and
then totalized on the display. In many cases the incoming pulses do not represent
the desired display readout. For those applications, a scale factor can be entered
into the meter, scaling the pulses to obtain the desired readout. The following
formula will help provide the scaling values to achieve the desired readout.
SF = DR
EPU
WHERE:
SF = Scale Factor
DR = Desired Readout* (Single unit of measure, i.e. foot, gallon, etc.)
EPU = Existing Pulses per Unit (Number of pulses per single unit of
measure, i.e. foot, gallons, etc.)
*For applications requiring a decimal point, select and program the
appropriate decimal point. When calculating the Scale Factor, use the whole
value of the number to be displayed, for example, 1.0 feet, the Desired
Readout in this case is 10. Do not use decimal points in the Scaling Formula.
For calculated SF values less than 9.99999
If the Scale Factor is a value less than 9.99999, it can be entered directly
into the meter as the Scale Factor and the Scale Multiplier can be left at 1.
For calculated SF values greater than 9.99999
If the Scale Factor is a value over 9.99999 (maximum value), the Scale
Multiplier must be used to reduce the calculated SF value until it is less then
9.99999. The Scale Multiplier multiplies the calculated Scale Factor value by
1, 0.1, and 0.01, thus reducing the calculated value accordingly. Select the
appropriate Scale Multiplier value that allows the Scale Factor to be a value
under 9.99999. Both the Scale Factor and Scale Multiplier can then be
entered into the meter.
Example 1:
This application involves counting cases from a production line. The sensor
provides a pulse for every can produced. The desired readout is in cases,
therefore the incoming pulses need to be converted to obtain the proper readout.
The following is used to calculate scale factor.
SF = DR
EPU
DR = 1 case
EPU = 12 cans/case
SF = 1
12
SF = 0.083333
Since the Calculated Scale Factor Value is less than 9.99999, it can be
entered directly into the meter. The Scale Multiplier can be left at 1.

desired selection is displayed. Press the PAR key to save the selection and exit
programming mode.
The totalizer may be programmed to reset at each meter power-up.
COUNTER RESET AT POWER-UP
PROGRAMMING MODE EXIT
The meter exits Programming Mode when the PAR key is pressed to save the
Scale Multiplier selection. The meter briefly displays upon exiting
Programming Mode. All programmed selections are now transferred to the nonvolatile memory and the meter returns to the Counter display.
(If power loss occurs during programming mode, verify parameter changes
and reprogram, if necessary, when power is restored.)
PROGRAMMING MODE TIME OUT
The Programming Mode has an automatic time out feature. If no keypad
activity is detected for approximately 60 seconds, the meter automatically exits
Programming Mode. The meter briefly displays and returns to the Counter
display. When automatic timeout occurs, any changes that were made to the
parameter currently being programmed, will not be saved.
FACTORY SETTINGS
The factory settings for the programming parameters are shown above in the
alternating display illustrations. The factory settings can be easily restored by
removing power from the meter, and then pressing and holding the PAR key
while power is reapplied. The meter displays until the PAR key is
released. The normal power-up sequence then resumes, with the factory settings
loaded and saved in non-volatile memory. The Count is reset to 0.
Note: The Program Disable DIP switch must be in the Enabled (down)
position to allow loading factory settings. See section on DIP switch setup.
