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.
DIMENSIONS In inches (mm)
Note: Recommended minimum clearance (behind the panel) for mounting clip installation is
2.1" (53.4) H x 5" (127) W.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to

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.
