GENERAL DESCRIPTION
The PAX®Lite Process Time Meter, Model PAXLPT, displays a value
representing the time between a beginning and end point of a process, such as a
conveyor oven.
The PAXLPT’s display will update inversely in relation to the input signal
frequency. As input frequency increases (representing speed), the PAXLPT
time display will decrease indicating a reduction in the duration of process
time. For example, the bake time through an oven will decrease the faster the
conveyor runs.
The display can be programmed for two operating modes. Operating in the 6
digit mode, the PAXLPT can readout in any whole value, such as seconds,
minutes, or hours. This mode also provides capability for decimal points. The 5
digit mode functions as a chronometer, which has a maximum display value of
999-59. This formats the display to allow the meter to readout in hours and
minutes, minutes and seconds, etc.
The PAX Lite Process Time Indicator also has a feature called “moving
window average”. This allows one time disturbances, or irregularly spaced
items to be averaged over eight inputs, thus keeping display fluctuations to a
minimum while still updating the display on every pulse. This feature can be
enabled or disabled by a rear DIP switch.
The PAXLPT can accept many different types of sensors including magnetic
pickups, logic sensors, and NPN open collector sensors, as well as switch
contact closure sensors.
The meter has been specifically designed for harsh industrial environments.
With a NEMA 4X/IP65 sealed bezel and extensive testing to meet CE
requirements, the meter provides a tough yet reliable application solution.

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 [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 has a jumper and switches, which must be checked and/or changed
prior to applying power. To access the power switch and the jumper, 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.
Power Selection Switch
Caution: Insure the AC power selection switch is set for the
proper voltage before powering-up the meter. The meter is shipped
from the factory in the 230 VAC position.

2.0 SETTING THE JUMPER AND SWITCHES
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 Electro-
Magnetic 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.

4.0 REVIEWING THE FRONT BUTTONS AND DISPLAY
In many industrial applications, a meter is required to display the process
time of an operation or event. The pulses from a sensor are received by the
PAXLPT, and then scaled to produce just such a readout. The following formula
will help provide the scaling values to achieve the desired readout.
SF = DR x PPS
WHERE:
SF = Scale Factor
DR = Desired Readout*
PPS = Pulses per Second
To calculate the PPS multiply the RPM (Revolutions per Minute) by the PPR
(Pulses per Revolution) and divide by 60.
RPM x PPR
60
*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, 50.0 minutes, the Desired
Readout in this case is 500. Do not use decimal points in the Desired Readout
when calculating the scale factor.
For calculated SF values less than 59,999
If the Scale Factor is a value less than 59,999, 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 59,999
If the Scale Factor is a value over 59,999 (maximum value), the Scale
Multiplier must be used to reduce the calculated Scale Factor value until it is
less than 59,999. The Scale Multiplier divides the calculated Scale Factor
value by 1, 10, 100 and 1000, thus reducing the calculated value accordingly.
Select the appropriate Scale Multiplier value that allows the Scale Factor to
be a value under 59,999. Both the Scale Factor and Scale Multiplier can then
be entered into the meter.
Example 1 (6 Digit):
DR = 150 minutes
PPS = 450 RPM x 60 PPR
60
PPS = 450
SF = DR x PPS
SF = 150 x 450
SF = 67,500
Since the SF value is greater than 59,999, the SM will be needed to reduce
the calculated value to value less than 59,999. Using the SM of 10, the 67,500
value is divide by 10, reducing the SF to a value of 6750. The meter can be
programmed for a SF of 6750 and a SM of 10.
Example 2 (5 Digit):
DR = 2 hours and 23 minutes (2-23)
PPS = 138 RPM x 100 PPR
60
PPS = 230
To calculate the Scale Factor for a 5 Digit application, first convert the DR
to its base units.
DR = 2 (hours) x 60 + 23
DR = 120 + 23
DR = 143 minutes
SF = DR x PPS
SF = 143 x 230
SF = 32,890
Since the SF value is less than 59,999, it can be entered directly as the SF
and the SM will be 1. Note: When programmed for the 5 Digit mode, the
meter will convert the D.R. back to the hours and minutes format.

The Process Time Indicator has three programmable parameters which are
entered in the sequence shown above, using the front panel push buttons.
Before programming, please refer to the section on Scaling the Meter to
determine the Decimal Position, Scale Factor and Scale Multiplier to use for the
specific application.
Note: Programming mode can be locked out with the Program Disable DIP
switch. With the switch in the Disabled (up) position the meter will not enter
programming mode. Refer to the section on DIP switch setup.
PROGRAMMING MODE ENTRY
Press the PAR key to enter Programming Mode. The meter briefly displays
 followed by the first programming parameter described below.
PROGRAMMING PARAMETERS
In programming mode, the display alternates between the parameter and the
current selection or value for that parameter. The dual display with arrows is
used below to illustrate the alternating display. The selection choices or value
range for each parameter is shown to the right of the alternating display.
This parameter selects the decimal point position on the
display. The selection is used when calculating the Scale Factor. This parameter
only appears when the meter is configured for the conventional (6-digit) display.
Press the arrow keys (or ) to sequence through the selection list until the
desired selection is shown. Press the PAR key to save the displayed selection
and advance to the next parameter.
The Scale Factor is used in combination with the Scale Multiplier to obtain
the desired process time readout. (See details on Scaling the Meter.)
The Scale Factor is displayed as a five-digit value with one selected digit
flashing (initially digit 5). Press the (up arrow) key to increment the value of
the selected (flashing) digit. Holding the key automatically scrolls the value
of the selected digit.
Press the (down arrow) key to select the next digit position to the right.
Use the key to increment the value of this digit to the desired number. Press
the key again to select the next digit to be changed. Repeat the “select and
set” sequence until all digits are displaying the desired Scale Factor value. Press
the PAR key to save the displayed value and advance to the next parameter.
Holding the key automatically scrolls through each digit position.
The Scale Multiplier is used in combination with the Scale Factor to obtain
the desired process time readout. (See details on Scaling the Meter.)
Press the arrow keys (or ) to sequence through the selection list until the
desired selection is displayed. Press the PAR key to save the selection and exit
programming mode.
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 non-
volatile memory and the meter returns to the Process Time 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 Process
Time 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.
Note: The Program Disable DIP switch must be in the Enabled (down)
position to allow loading factory settings. See section on DIP switch setup.
