Figure 523: Three shots with three initiation lines

INIT_3 lines, the sequence is two shots long.

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.
