2.1 SETTING THE JUMPER
The meter has one jumper for user input logic. When using the user inputs
this jumper must be set before applying power. The Main Circuit Board figure
shows the location of the jumper and DIP switch.
The user input jumper determines signal logic for the user inputs, when they
are used with user functions or for input signal direction. All user inputs are set
by this jumper.
2.2 SETTING THE INPUT DIP SWITCHES
The meter has six DIP switches for Input A and Input B terminal set-up that
must be set before applying power.
SWITCHES 1 and 4
LOGIC: Input trigger levels V IL
= 1.5 V max.; V
IH
= 3.75 V min.
MAG: 200 mV peak input (must also have SRC on). Not recommended with
counting applications.
SWITCHES 2 and 5
SNK.: Adds internal 7.8 K
 pull-up resistor to +12 VDC, I
MAX
= 1.9 mA.
SRC.: Adds internal 3.9 K
 pull-down resistor, 7.3 mA max. @ 28 VDC,
V
MAX
= 30 VDC.
SWITCHES 3 and 6
HI Frequency: Removes damping capacitor and allows max. frequency.
LO Frequency: Adds a damping capacitor for switch contact bounce. Also
limits input frequency to 50 Hz and input pulse widths to 10 msec.

To access the jumper and switches, remove the meter base from the meter
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 meter and load circuits before accessing inside of
the meter.

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 operating
temperature and provides good air circulation. Placing the unit 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 unit.
