It is assumed that there is an 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.

Functional diagrams for control and interlocking

Two types of disconnector and earthing switch function blocks are available.
DCSXSWI1...3 and ESSXSWI1...2 are status only type, and DCXSWI1...2 and
ESXSWI1 are controllable type. By default, the status only blocks are connected in
standard configuration. The disconnector (CB truck) and line side earthing switch
status information are connected to DCSXSWI1 and ESSXSI1.
The configuration includes closed enable interlocking logic for disconnector and
earthing switch. These signals are available for binary outputs X100:SO1 and
X100:SO2.
