BE1-BPR Application

2-15

for trip coil continuity. Refer to

Application Data in this section information for further details on the circuit

operation.

4.

Breaker Arc Protection. Preprogrammed logic is provided using fault detector 3 (F3) for the MAF fault
detector, IN1 for breaker status, and OUT4 for the arc detector output. Refer to

Application Data in this

section for further details on the circuit operation.

5.

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.

6.

Alarm Output. An Alarm output is provided to signal relay failure or diagnostic alarm.
