Figure 278: Three shots with three initiation lines
If the sequence is initiated from the
INIT_1
line, that is, the overcurrent protection high
stage, the sequence is one shot long. On the other hand, if the sequence is initiated from
the
INIT_2
or
INIT_3
lines, the sequence is two shots long.

7.2.6.4 Delayed initiation lines
The autoreclose function consists of six individual autoreclose initiation lines
INIT_1...INIT 6
and three delayed initiation lines:
• DEL_INIT_2
• DEL_INIT_3
• DEL_INIT_4
DEL_INIT_2
and
INIT_2
are connected together with an OR-gate, as are inputs 3 and
4. Inputs 1, 5 and 6 do not have any delayed input. From the autoreclosing point of view,
it does not matter whether
INIT_x
or
DEL_INIT_x
line is used for shot initiation or
blocking.
The autoreclose function can also open the circuit breaker from any of the initiation lines.
It is selected with the
Tripping line setting. As a default, all initiation lines activate the
OPEN_CB
output.
