Figure 330: Signal scheme of autoreclosing operation initiated with protection
start signal
The autoreclosing shot is initiated with a start signal of the protection function after the
start delay time has elapsed. The autoreclosing starts when the
Str 2 delay shot 1
setting elapses.

Figure 331: Signal scheme of autoreclosing operation initiated with protection
operate signal
The autoreclosing shot is initiated with a trip signal of the protection function. The
autoreclosing starts when the protection operate delay time elapses.
Normally, all trip and start 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.
