The signal CBF_1: Trip signal (or CBF_2: Trip signal, . . ., resp.) is
issued when this timer stage's time duration has elapsed.

If during this delay time period the circuit breaker does not provide a signal from
its auxiliary contacts that it is closed, then faults behind the CB are recognized
through the current criterion (see section “Fault behind CB protection”).
