Description
Synchro-check/energizing OK. The output sig-
nal is high when the synchro-check conditions
set on the MMI are fulfilled. It can also include
the energizing condition, if selected. The signal
can be used to release the auto-recloser before
closing attempt of the circuit breaker. It can also
be used as a free signal.
Same as above but with alternative settings of
the direction for energizing to be used during
manual closing of the circuit breaker.
