Fig. 5.1.11.-2 Operating principle of the trip-circuit supervision (TCS), with an
external resistor. The TCS blocking switch is open, enabling trip-
circuit supervision independent of circuit breaker position. The
terminal numbers are related to HSPO1.
5.1.11.1. Configuring the trip circuit supervision CMTCS_
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:
TCS1 and TCS2 inputs in REF 545:
For more information about the trip circuit supervision function, refer to the CD-
ROM “Technical Descriptions of Functions”.
5.1.12. Self-supervision (IRF)
The REF 54_ feeder terminal is provided with an extensive self-supervision system.
The self-supervision system handles run-time fault situations and informs the user
of faults via the HMI and LON/SPA communication. See also
