Simulation without tripping the
circuit breaker:
The TripCmd of all protection
functions will be blocked. The
protection function will possibly
trip but not generate a TripCmd.

Force Post: As soon as this signal
becomes true, the Fault Simulation will be
forced to switch into the Post Failure mode.

Manual start, manual stop
As soon as this signal becomes true, the

Start by external signal
The start of the Fault Simulator is triggered
by the assigned external signal (unless a
phase current exceeds 0.1 ⋅ In or the Fault
Simulator is blocked, see also description
above).
