The Relay Configuration Tool can be used to connect the trip circuit supervision
input status signals to the function blocks CMTCS1 and CMTCS2. The
configuration of the blocking signal is user-specific and can only be defined in the
feeder terminal configuration. The trip circuit supervision inputs in the feeder
terminal configuration are as follows:
TCS1 and TCS2 inputs in REF 541 and REF 543:
Trip Circuit Supervision 1 input
Trip Circuit Supervision 2 input
TCS1 and TCS2 inputs in REF 545:
Trip Circuit Supervision 1 input
Trip Circuit Supervision 2 input
