When the reclosing is initiated with pickup of the protection function, the autoreclosing
function can execute the final trip of the circuit breaker in a short trip time, provided that
the fault still persists when the last selected reclosing has been carried out.
9.2.3.1 Protection signal definition
The Control line setting defines which of the initiation signals are protection pickup and
trip signals and which are not. With this setting, the user can distinguish the blocking
signals from the protection signals. The
Control line setting is a bit mask, that is, the lowest
bit controls the
INIT_1
line and the highest bit the
INIT_6
line. Some example
combinations of the Control line setting are as follows:
Table 367: Control line setting definition

1 prot other other other other other
2 other prot other other other other
3 prot prot other other other other
4 other other prot other other other
5 prot other prot other other other
...63 prot prot prot prot prot prot
prot = protection signal
other = non-protection signal
When the corresponding bit or bits in both the Control line setting and the
INIT_X
line
are TRUE:
• The
CLOSE_CB
output is blocked until the protection is reset
• If the
INIT_X
line defined as the protection signal is activated during the
discrimination time, the AR function goes to lockout
• If the
INIT_X
line defined as the protection signal stays active longer than the time
set by the Max trip time setting, the AR function goes to lockout (long trip)
• The
UNSUC_RECL
output is activated after a pre-defined two minutes (alarming
ground-fault).
