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.
