Description of the general autoreclose status:
OUT OF SERVICE / AR DISABLE
In this status, the autoreclose is disabled. From any state, if the Function setting is set as DISABLED, the autoreclose will
move to OUT OF SERVICE status, where it is not operative.
AR READY
This is the initiation and normality situation status: closed breaker. There are neither faults producing a autoreclose
initiation nor Block signal.
If the autoreclose was in LOCKOUT, if the breaker is closed and the time set in Reclaim Time setting expires, the
autoreclose will go to the initial status of READY.
From RECLOSE IN PROGRESS, the recloser will move to READY, if the Reset Time setting expires without any
autoreclose initiation condition.
AR RECLOSE IN PROGRESS
From READY status, a reclose initiation will set the cycle counter to 1 and a reclosing sequence will be initiated which
will produce breaker close commands, unless any abnormality is produced that will make the autoreclose go to
LOCKOUT status.
The reclosing sequence consists on the following steps:
Wait until the breaker is open, if the waiting exceeds the Fail to Open Time setting, the autoreclose will go to
LOCKOUT by failure of opening status (AR LCK BY FAIL OPEN).
