Figure 508: Signal scheme of autoreclosing operation initiated with protection trip
signal
The autoreclosing shot is initiated with a trip signal of the protection function. The
autoreclosing picks up when the protection trip delay time elapses.
Normally, all trip and pickup signals are used to initiate an autoreclosing shot and trip the
circuit breaker. ACTIVE output indicates reclosing sequence in progress. If any of the
input signals INIT_X or DEL_INIT_X are used for blocking, the corresponding bit in
the Tripping line setting must be FALSE. This is to ensure that the circuit breaker does not
trip from that signal, that is, the signal does not activate the OPEN_CB output. The default
value for the setting is "63", which means that all initiation signals activate the OPEN_CB
output. The lowest bit in the Tripping line setting corresponds to the INIT_1 input, the
highest bit to the INIT_6 line.
