2.22.2 Trip Circuit Supervision
The line protection 7SD5 is equipped with an integrated trip circuit supervision func-
tion. Depending on the number of available binary inputs (not connected to a common
potential), supervision with one or two binary inputs can be selected. If the routing of
the binary inputs required for this does not comply with the selected supervision mode,
an alarm is given („TripC1 ProgFAIL ...", with identification of the non-compliant cir-
cuit). When using two binary inputs, malfunctions in the trip circuit can be detected
under all circuit breaker conditions. When only one binary input is used, malfunctions
in the circuit breaker itself cannot be detected. If single-pole tripping is possible, a sep-
arate trip circuit supervision can be implemented for each circuit breaker pole provided
the required binary inputs are available.
