SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in this

literature or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired. Do not use this unit to directly

command motors, valves, or other actuators not equipped with safeguards. To do

so can be potentially harmful to persons or equipment in the event of a fault to

the unit.

METER INSTALLATION

The PAX2D 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.

SETTING THE DIP SWITCHES

To access the switches, 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.

Warning: Exposed line voltage exists on the circuit boards. Remove all

power to the meter and load circuits before accessing inside of the

meter.

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 sensitivity; 100 mV hysteresis; maximum voltage:

± 40 V peak (28 Vrms); Input impedance: 3.9 KΩ @ 60 Hz; Must also have SRC

switch ON. (Not recommended with counting applications.)

SWITCHES 2 and 5

SNK.: Adds internal 7.8 KΩ pull-up resistor to +5 VDC, I

MAX

= 0.7 mA.

SRC.: Adds internal 3.9 KΩ 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 maximum 50 Hz and input pulse widths to minimum

10 msec.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

CAUTION:

Risk of electric shock.
