For the 3rd cycle:
For the 4th cycle:
5th to 8th reclosure
cycle
If more than four cycles were set during configuration of the functional scope, the dead
times preceding the fifth (5th) through the ninth (9th) reclosing attempts are equal to
the open breaker time which precedes the fourth (4th) reclosing attempt.
Notes on the Infor-
mation 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.
„>BLK 1.AR-cycle“ (No. 2742) to „>BLK 4.-n. AR“ (No. 2745)
The respective auto-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 internally blocked. If the block signal of a cycle
appears while this cycle is being executed (in progress), the automatic reclosure func-
tion is blocked dynamically; no further automatic reclosures cycles are then executed.
