3.
Trip Coil Status Monitor
. Preprogrammed logic is provided using IN1 to provide breaker status and IN2 for
trip coil continuity.
4.
Breaker Arc Protection
. Preprogrammed logic is provided using fault detector (F3) for the moving average
fault detector, IN1 for breaker status and OUT4 for the arc detector output.
5.
Block Reclose Output
. Preprogrammed logic is provided using breaker resistor protection output (O13) to
drive the Block Reclose (BR) output (OUT3).
6.
Retrip Output
. A Retrip output is provided to give a backup trip signal to the breaker trip coil. This can either
provide a separate path to a single trip coil or be hooked to the backup trip coil if available.
7.
External Fault Trigger
. The enhanced BE1-BPR relay provides the ability to save COMTRADE fault records for
twelve events in memory at one time. An external fault trigger is provided to allow other multiple units to record
the same event.
8.
Alarm Output
. An Alarm output is provided to signal relay failure or diagnostic alarm.
