Figure 138: Logic for circuit breaker monitoring alarm
Two separate trip circuit supervision functions are included: TCSSCBR1_TCM-1 for
power output X100:PO3 and TCSSCBR2_TCM-2 for power output X100:PO4. Both the
functions are blocked by the master trips TRPPTRC1_86/94-1 and TRPPTRC2_86/94-2
and the circuit breaker open signal.
It is assumed that there is no external resistor in the circuit breaker tripping
coil circuit connected in parallel with the circuit breaker normally open
auxiliary contact.
