Figure 377: Signal scheme of autoreclose operation initiated with protection
start signal
The auto-reclose shot is initiated with a start signal of the protection function after
the start delay time has elapsed. The auto-reclose starts when the Str 2 delay shot 1
setting elapses.

Figure 378: Signal scheme of autoreclose operation initiated with protection
operate signal
The auto-reclose shot is initiated with a trip signal of the protection function. The
auto-reclose starts when the protection operate delay time elapses.
Normally, all trip and start signals are used to initiate an auto-reclose shot and trip
the circuit breaker. 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.
