Single Position Indication Aux CLOSE or Aux OPEN
If the single pole indication is used, the »SI S

The moving time supervision works only in one direction. If the Aux OPEN signal is connected to the device, only the
“OPEN command” can be supervised and if the Aux CLOSE signal is connected to the device, only the “CLOSE
command” can be supervised.
Single Position Indication – Aux CLOSE
If only the Aux CLOSE signal is used for the Status Indication of an “CLOSE 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 CLOSE 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 CLOSE.
The following table shows how breaker positions are validated based on Aux CLOSE:
