2. Connect jumper wires to the sensor wiring har-
ness:
a. Connect positive (24 volts) to the pin #1 of the
connector. See Figure 21.
b. Connect a ground to the pin #2 of the connec-
tor.
c. Connect a voltmeter between pin #3 of the
connector and a ground.
3. Position a piece of metal within 5.0 mm (0.2 in.) of
the face of the sensor to activate the sensor. Re-
move your hand to deactivate. Voltmeter should
read 24 volts when the sensor is activated and no
voltage when it is deactivated. If the sensor does
not operate correctly, it must be replaced.
