Figure 340: Logic diagram of auto-initiation sequence detection
Automatic initiation can be selected with the Auto initiation Cnd setting to be the
following:
• Not allowed: no automatic initiation is allowed
• When the synchronization fails, the automatic initiation is carried out when the
auto wait time elapses and the reclosing is prevented due to a failure during the
synchronism check
• When the circuit breaker does not close, the automatic initiation is carried out if
the circuit breaker does not close within the wait close time after issuing the
reclose command
• Both: the automatic initiation is allowed when synchronization fails or the circuit
breaker does not close.
