Siemens 7SJ82 - Settings

Output signal: Retrip T1
The output signal Retrip T1 must be routed to a binary output.
If only one control circuit is available for the local circuit breaker, the output signal must be routed to the
binary output to which the general circuit breaker trip command (command Position ) is routed.
If a second control circuit is present, the Retrip T1 output signal can be routed to the associated binary
output.
Output signal:
Trip T2
In order to trip the adjacent circuit breakers, the backup tripping (indication Trip T2 ) must be routed to a
binary output and if necessary, to an interface (intertripping to the opposite end). Thus, the circuit breaker on
the opposite end can be tripped without delay.
