6.12.4 Information Overview
The most important information about automatic reclosure is briefly explained
insofar as it was not mentioned in the following lists or described in detail in the
preceding text.
“!%/.$5F\FOH” (F.No. ) to “!%/.Q$5” (F.No. )
The corresponding reclose cycle is blocked. If the blocking state already exists when
the automatic reclosure function is initiated, the blocked cycle is not executed and may
be skipped (if other cycles are permitted). The same applies if the automatic
reclosure function is started (running) but not busy with (inside) the cycle being
blocked. If the block signal of a cycle appears while this cycle is being executed (busy)
the automatic reclosure function is blocked dynamically; no further automatic
reclosures cycles are then executed.

The automatic reclosure function is ready for the corresponding reclosure cycle. This
