6.1.3 Functionality
The trip circuit supervision function TCM is designed to supervise the control circuit of
the circuit breaker. The invalidity of a control circuit is detected by using a dedicated
output contact that contains the supervision functionality. The failure of a circuit is
reported to the corresponding function block in the relay configuration.
The function picks up and trips when TCM detects a trip circuit failure. The operating time
characteristic for the function is of the definite time (DT) type. The function trips after a
predefined operating time and resets when the fault disappears.
The function contains a blocking functionality. Blocking deactivates the ALARM output
and resets the timer.
6.1.4 Operation principle
The function can be enabled and disabled with the Operation setting. The corresponding
parameter values are “Enable” and “Disable”.
