• 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 auto-reclosing point
of view, it does not matter whether
INIT_x
or
DEL_INIT_x
line is used for shot
initiation or blocking.
The auto-reclose 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.
