Functional diagrams for condition monitoring

Two trip circuit monitoring stages TCSSCBR1_TCM-1 and TCSSCBR2_TCM-2 are
provided to supervise the trip circuit of the circuit breaker connected at PO3 (X100:15-19)
and PO4 (X100:20-24).

TRPPTRC2_86_94-2_TRIP
The TCSSCBR1_TCM-1 and TCSSCBR2_TCM-2 functions are blocked by
TRPPTRC1_86/94-1, TRPPTRC2_86/94-2 and when the circuit-breaker is not in closed
position.
By default it is expected that there is no external resistor in the circuit
breaker tripping/closing coil circuit connected parallel with circuit
breaker normally open/closed auxiliary contact.
The circuit breaker condition monitoring function SSCBR1_52CM supervises the circuit
breaker status based on the binary input information connected and measured current
levels. The function introduces various supervision alarms.
