Switchgear/Breaker – Manager
Single Position Indication Aux ON or Aux OFF
If the single pole indication is used, the »SI SINGLECONTACTIND« will become true.
The moving time supervision works only in one direction. If the Aux OFF signal is connected to the device, only the
“OFF command” can be supervised and if the Aux ON signal is connected to the device, only the “ON command”
can be supervised.
Single Position Indication – Aux ON
If only the Aux ON signal is used for the Status Indication of an “ON command”, the switch command will also start
the moving time, the position indication indicates an INTERMEDIATE position during this time interval. When the
switchgear reaches the end position indicated by the signals Pos ON and CES succesf before the moving time has
elapsed the signal Pos Indeterm disappears.
If the moving time elapsed before the switchgear has reached the end position, the switching operation was not
successful and the Position Indication will change to POS Disturb and the signal Pos Indeterm disappears. After the
moving time has elapsed, the Dwell time will be started (if set). During this time interval the Position Indication will
also indicate an INTERMEDIATE state. When the Dwell time elapses the Position Indication will change to Pos ON.
The following table shows how breaker positions are validated based on Aux ON:
