AR01-SYNC Synchro-check OK from the internal synchro-
check function or an external device required for
three-phase auto-reclosing.
AR01-PLCLOST Power line carrier or other form of permissive sig-
nal lost. An optional input signal at loss of a com-
munication channel in a permissive line protection
scheme. Can extend the AR open time.
AR01-TRSOTF Protection trip switch-onto-fault.
AR01-TPTRIP Three-phase trip. Signal to the auto-reclosing func-
tion that a three-phase tripping occurred.
AR01-WAIT Signal to the low priority auto-reclosing function
from the master in multi-breaker arrangements for
sequential reclosing.
Output signals:
AR01-SETON Indicates that the AR operation is On, that is, opera-
tive.
AR01-READY Indicates that the AR function is ready for a new
AR cycle. It is On and it is not started or blocked.
AR01-INPROGR Auto-reclosing in progress. Activated during the
AR open time.
AR01-SP1 Auto-reclosing single-phase, Shot 1 in progress.
AR01-TP1 Auto-reclosing three-phase, Shot 1 in progress.
AR01-TP2 Auto-reclosing three-phase, Shot 2 in progress.
AR01-UNSUC Auto-reclosing unsuccessful. Activated at a new
trip after the last programmed shot.
AR01-CLOSECB Close circuit-breaker command.
AR01-P3PH Prepare three-phase trip. Control of the next trip
operation.
AR01-P1PH Permit single-phase trip. Inverse signal to AR01-P3PH.
AR01-WFMASTER Wait from master. Issued by the high priority unit
for sequential reclosing.
AR01-LONGDURA Output signal inhibiting the auto-reclosing when
the extension of AR OPEN TIME is set off.
2.2 AR Operation You can control the auto-reclosing function from the MMI. Use the Operation
parameter, which you can set to Off, Stand by or On. See Fig. 3.
Off deactivates the Operation parameter. On activates automatic reclos-
ing. Stand by enables On and Off Operation via input signal pulses.
