INSTALLATION
The PAX2C meets NEMA 4X/IP65 requirements when properly installed.
The controller is intended to be mounted into an enclosed panel. Prepare the
panel cutout to the dimensions shown. Remove the panel latch from the
controller. Slide the panel gasket over the rear of the controller to the back of
the bezel. The controller should be installed fully assembled. Insert the
controller into the panel cutout.
While holding the controller in place, push the panel latch over the rear of the
controller so that the tabs of the panel latch engage in the slots on the case. The
panel latch should be engaged in the farthest

eTTing The
The PAX2C controller has 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 controller 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.
Warning: Exposed line voltage exists on the circuit boards. Remove
all power to the controller and load circuits before accessing inside
of the controller.

INPUT RANGE JUMPERS
Voltage Input
Two jumpers are used in configuring the controller for voltage/resistance.
The first jumper, T/V, must be in the V (voltage) position. The second jumper is
used to select the proper voltage input range. (This jumper is also used to select
the current input range.) Select a range that is high enough to accommodate the
maximum signal input to avoid overloads. For proper operation, the input range
selected in programming must match the jumper setting.

seal, tighten the latch screws evenly until
the controller is snug in the panel

INSTALLATION ENVIRONMENT
The controller should be installed in a location that does not exceed the
operating temperature and provides good air circulation. Placing the controller
near devices that generate excessive heat should be avoided.
The bezel should only be cleaned 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 controller.

Current Input
For current input, only one jumper must be configured to select the current
range. This jumper is shared with the voltage input range. To avoid overloads,
select the jumper position that is high enough to accommodate the maximum
signal input level to be applied.
Note: The position of the T/V jumper does not matter when the controller is
in the current input mode.
Temperature Input
For temperature measurement the T/V jumper must be in the T (temperature)
position. For RTD sensors the RTD jumper must also be set.
Resistance Input
Three jumpers are used to configure the resistance input. The T/V jumper
must be in the V (voltage) position, and the excitation jumper must be in the
1.05 mA REF position. The voltage/resistance jumper position is determined by
the input range.
Excitation Output Jumper
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.
