Figure 263: Signal scheme of autoreclose operation initiated with protection pickup
signal
The autoreclose shot is initiated with a trip signal of the protection function after the
pickup delay time has elapsed. The autoreclose picks up when the
Str 2 delay shot 1 setting
elapses.
Figure 264: Signal scheme of autoreclose operation initiated with protection trip
signal
The autoreclose shot is initiated with a trip signal of the protection function. The
autoreclose picks up when the protection trip delay time elapses.
Normally, all trip and pickup signals are used to initiate an autoreclose 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.
