for tSlaveDeadTime is 0.1sec because both master and slave should not send the
breaker closing command at the same time. The slave should take the duration of the
breaker closing time of the master into consideration before sending the breaker
closing command. A setting tW
aitForMaster sets a maximum wait time for the WAIT
input to reset. If the wait time expires, the reclosing cycle of the slave is inhibited. If
auto reclosing of the first breaker is unsuccessful, the UNSUCCL output connected to
the INHIBIT input of the slave unit interrupts the auto reclosing sequence of the latter.
The signals can be cross-connected to allow simple changing of the
priority by just setting the High and the Low priorities without
changing the configuration. The input 52a for each circuit breaker is
important in multi-breaker arrangements to ensure that the circuit
breaker was closed at the beginning of the cycle. If the High priority
circuit breaker is not closed the High priority moves to the low priority
circuit breaker.
