a. Test. Test the under/over voltage module as
follows:
(1) Under/over voltage relay (11, figure 15-9)
(a) Connect the under/over voltage
device as shown in figure 15-10.
(b) Close S1, adjust variac for 110V
AC on AC voltmeter.
(c) With ohmmeter connected between
terminals 5 and 7, reduce AC
voltage. Relay should trip at 103V
AC at this point, ohmmeter will no
longer show continuity.
(d) With ohmmeter connected between
terminals 5 and 6 adjust AC voltage
to read 130 volts.
(e) Increase voltage. Relay should trip
at 132V AC. Ohmmeter will no
longer show continuity.
b. Replacement.
WARNING
REMOVE 120V AC POWER PRIOR TO MOVING AND
REPLACING DEVICE.
