DEADT IN PROG (DEAD TIME IN PROGRESS)

The Dead T in Prog output indicates that the dead time is in progress. This signal is set when Reclose Checks is set
AND input Dead TimeEnabled is high. This may be useful during commissioning to check the operation of the
Autoreclose cycle.
5.10

DT COMPLETE (DEAD TIME COMPLETE)

DT Complete (Dead time complete) operates at the end of the set dead time, and remains operated until either the
scheme resets at the end of the reclaim time or a further protection operation or Autoreclose initiation occurs. It
can be applied purely as an indication, or included in PSL mapping to logic input DAR Complete.
5.11

AR SYNC CHECK (AR SYNCHRONISATION CHECK)

AR Sync Check indicates that the Autoreclose Synchronism checks are satisfactory. This is when either of the
synchronisation check modules (CS1 or CS2), confirms an In-Synchronism condition.
5.12

AR SYSCHECKS OK (AR SYSTEM CHECKS OK)

AR SysChecks OK indicates that the Autoreclose System checks are satisfactory. This is when any selected system
check condition (synchronism check, live bus/dead line etc.) is confirmed.
This DDB signal ihas the number 463 and is an output from the Autoreclose function (i.e. a PSL input). It should not
be confused with DDB signal 403, which is an input to the Autoreclose function (i.e. a PSL output).
5.13

AUTO CLOSE

The Auto Close output indicates that the Autoreclose logic has issued a Close signal to the CB. This output feeds
a signal to the control close pulse timer and remains on until the CB has closed. This signal may be useful during
commissioning to check the operation of the Autoreclose cycle.
5.14

PROTECTION LOCKT (PROTECTION LOCKOUT)

Protection Lockt (Protection Lockout) operates if AR lockout is triggered by protection operation either during the
inhibit period following a manual CB close or when the device is in Non-auto or Live Line mode.
5.15

RESET LCKOUT ALM (RESET LOCKOUT ALARM)

Reset Lckout Alm operates when the device is in Non-auto mode, if the Reset Lockout setting is set to Select
Non Auto.
5.16

RECLAIM IN PROG

Reclaim in Prog output indicates that a reclaim timer is in progress and will drop-off once the reclaim timer resets.
5.17

RECLAIM COMPLETE

Reclaim Complete operates at the end of the set reclaim time and is a fast reset. To maintain the output indication
a dwell timer has to be implemented in PSL.
