Sync-check Override Conditions
If enabled the following conditions can override the sync-check function:
LBDL = Live Bus – Dead Line
•
DBLL = Dead Bus – Live Line

DBDL = Dead Bus – Dead Line

Also the sync-check function can be bypassed by an external source.
When the sync-check function is overridden or bypassed, synchronization
has to be secured by other synchronizing systems before breaker closing!
