CAUTION
Trip circuit voltage is present at the front panel test points. When shorting the test
points, use insulated jumpers to avoid contact with these voltages.

The microprocessor performs the program operations based on the inputs and the internal software
program. When the sensed current exceeds the TIME PICKUP setting, the TIME PICKUP LED is turned
ON. TIME contacts (51 and 51 AUX) are closed in accordance with the time characteristic curve. If the
sensed current exceeds the INST PICKUP setting, the INST contacts (50) are closed.
Power-Off Sensing
The power-off sensing circuits measure the decaying voltage to determine the length of time that power
is removed (zero current). This provides information for the integrating reset function even when power
has been entirely removed.
Outputs
Instantaneous And Timed
System circuit breakers controlled by the output contacts can be manually tripped by applying a short
across the TIME or INST MANUAL TRIP front panel test points. Current flow in the trip circuit is
indicated by the operation of the target. The targets will not operate without adequate operating power
for the relay.
Auxiliary
The auxiliary output contacts can be configured by the user to close when the timed and/or
instantaneous trip occurs. With both jumpers installed (this is the factory setting) either the timed or
instantaneous trip closes the auxiliary contacts.
