• inhibitWaitForMaster: after expiration of the tWaitForMaster time for the
WAIT input to reset, the reclosing cycle of the slave is inhibited.
• longStartInhibit: if start pulse duration is longer than the tLongStartInh time,
the reclosing cycle is inhibited.
The ABORTED output indicates that the auto recloser is inhibited while it was in
one of following internal states:
• inProgress: auto recloser is started and dead time is in progress.
• reclaimTimeStarted: the circuit breaker closing command has started the
reclaim timer.
• wait: an auto recloser, acting as slave, is waiting for a release from the master
to proceed with its own reclosing sequence.
The SYNCFAIL output indicates that the auto recloser is inhibited because the
synchrocheck or energizing check condition has not been fulfilled within the set
time interval, tSync. The ABORTED output will also be activated.
The behavior of the functionality described above is described in Table
177 and
Table
178 below.
