Service and Commissioning Support
Failure Simulator (Sequencer)*
Available Elements:
Sgen
* = Availability depends on ordered device.
For commissioning support and in order to analyze failures, the protective device offers the option to simulate
measuring quantities. The simulation menu can be found within the [Service/Test Mode/Sgen] menu.
The simulation cycle consists of three states:
Pre-failure;
Failure; and
Post-failure State (Phase).
Within the [Service/Test Mode/Sgen/Configuration/Times] sub-menu, the duration of each phase can be set. In
addition; the measuring quantities to be simulated can be determined (e.g.: voltages, currents, and the
corresponding angles) for each phase (and ground).The simulation will be terminated, if a phase current exceeds
0.1 times In. A simulation can be restarted, five seconds after the current has fallen below 0.1 times In.
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.
The energy counters will be stopped while the failure simulator is running.
