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.
Set the parameters for TCSSCBR1 properly.

Figure 86: Logic for blocking of trip circuit supervision
Protection communication supervision PCSITPC is used in the configuration to block
the operation of the line differential function. This way, the malfunction of the line
differential is prevented. The activation of binary signal transfer outputs during the
protection communication failure is also blocked. These are done internally without
connections in the configurations. The protection communication supervision alarm
is connected to the alarm LED 4, disturbance recorder and binary output X100:SO2.
