BE1-50/51B-Functional Description
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.

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. Effective with unit revision R, in units 9 2520 00 100 through 109, the printed
circuit board (PCB) was changed. Now, the PCB for 100 and 200 series relays are similar. User’s with units
previous to revision R may see Section 8, Relay Differences, for installing auxiliary contact jumpers.
