5th to 8th Reclose 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 circuit breaker time which
precedes the fourth (4th) reclosing attempt.
Notes on the Information List
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 function is
blocked dynamically; no further automatic reclosures cycles are then executed.
AR 1.CycZoneRel (No. 2889) to AR 4.CycZoneRel (No. 2892)
The automatic reclosure is ready for the respective reclosure cycle. This information indicates which cycle will
be run next. For example, external protection functions can use this information to release accelerated or
overreaching trip stages prior to the corresponding reclose cycle.
AR is blocked (No. 2783)
