SYNCHRONISATION CHECKS FOR CB CLOSURE

Logical checking of the outputs from the CB closure monitors is performed to generate signals to indicate that it is
OK to close circuit breakers.
Signals are provided to indicate that manual CB closure conditions are OK (CB Man SCOK), as are signals to
indicate that automatic CB closure conditions are OK (CB SCOK and CB Fast SCOK). The CB Fast SCOK signal
allows CB autoreclosure without waiting for the Dead Time to expire.
