Figure 539: 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 540: 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.
