Signals of a Monitored Disconnector
Signal Description
SI SingleContactInd Signal: The Position of the Switchgear is detected by one auxiliary contact
(pole) only. Thus indeterminate and disturbed Positions cannot be detected.
Pos not ON Signal: Pos not ON
Pos ON Signal: Circuit Breaker is in ON-Position
Pos OFF Signal: Circuit Breaker is in OFF-Position
Pos Indeterm Signal: Circuit Breaker is in Indeterminate Position
Pos Disturb Signal: Circuit Breaker Disturbed - Undefined Breaker Position. The Position
Indicators contradict themselves. After expiring of a supervision timer this
signal becomes true.
Pos Signal: Circuit Breaker Position (0 = Indeterminate, 1 = OFF, 2 = ON, 3 =
Disturbed)
Ready Signal: Circuit breaker is ready for operation.
t-Dwell Signal: Dwell time
Removed Signal: The withdrawable circuit breaker is Removed
Interl ON Signal: One or more IL_On inputs are active.
Interl OFF Signal: One or more IL_Off inputs are active.
CES succesf Signal: Command Execution Supervision: Switching command executed
successfully.
CES Disturbed Signal: Command Execution Supervision: Switching Command unsuccessful.
Switchgear in disturbed position.
CES Fail TripCmd Signal: Command Execution Supervision: Command execution failed
because trip command is pending.
CES SwitchDir Signal: Command Execution Supervision respectively Switching Direction
Control: This signal becomes true, if a switch command is issued even
though the switchgear is already in the requested position. Example: A
switchgear that is already OFF should be switched OFF again (doubly). The
same applies to CLOSE commands.
CES ON d OFF Signal: Command Execution Supervision: On Command during a pending
OFF Command.
CES SG not ready Signal: Command Execution Supervision: Switchgear not ready
CES Fiel Interl Signal: Command Execution Supervision: Switching Command not executed
because of field interlocking.
CES SyncTimeout Signal: Command Execution Supervision: Switching Command not
executed. No Synchronization signal while t-sync was running.
CES SG removed Signal: Command Execution Supervision: Switching Command unsuccessful,
Switchgear removed.
Prot ON Signal: ON Command issued by the Prot module
