NOTICE!
The simulation is terminated immediately, if a phase current exceeds 0.1 ⋅ In.
A simulation can be restarted, five seconds after the current has fallen below 0.1 ⋅ In.
Moreover, within the menu branch [Service / Test Mode (Prot inhibit) / WARNING! Cont? /
Sgen / Process] there are two blocking parameters »ExBlo1«, »ExBlo2«. Signals that are
assigned to any of these block the Fault Simulator. For example, it can be recommended
for security considerations to have the Fault Simulator blocked if the circuit breaker is in
closed position.
Furthermore, there is the possibility to assign a signal to the parameter »Ex ForcePost«.
Then this signal interrupts the actual state of the Fault Simulator (Pre-fault or Failure) and
leads to an immediate transition into the Post-fault state. The typical application for this
is a test whether the protective device correctly generates a trip decision, so that it is not
necessary to always wait until the regular end of the Failure state. It is possible to assign
the trip signal to »Ex ForcePost« so that the Failure state is ended immediately after the
trip signal has been correctly generated.
DANGER!
Setting the device into the simulation mode means taking the protective device out of
operation for the duration of the simulation. Do not use this feature during operation of
the device if the User cannot guarantee that there is a running and properly working
backup protection.
NOTICE!
The energy counters are stopped while the failure simulator is running.
NOTICE!
Due to internal dependencies, the frequency of the simulation module is 0.16% greater
than the rated one.
Start/Stop Options
Manual start, no stop:
Complete run: Pre Failure, Failure, Post Failure.
• Set [Service / Test Mode (Prot inhibit) / WARNING! Cont? / Sgen / Process] »Ex
ForcePost« = “No assignment”
• Press/Call the Direct Control [Service / Test Mode (Prot inhibit) / WARNING! Cont? /
Sgen / Process] »Start Simulation«.
