In Fig. 28 to Fig. 31, the SY_FAIL input supervises the synchronisation
time. If the relay does not reach synchronism within a certain time,
SY_FAIL is activated and resets the complete operation sequence.
4.2.9 Autoreclosing Fig. 32 shows the interaction between the autoreclosing (AR) module and
the apparatus control modules. The OR gate for the close signal must have
the same execution cyclicity as the autoreclosing module. The signal
BLK_AR from SWICON is used to block the autoreclose function at the
moment the circuit breaker is under operation.
