tive automatic reclosing cycle will be completely blocked. With the binary input
>Block 79 cycle
, you can
block the associated automatic reclosing cycle.
For applications with 1-pole tripping, the cycle control provides a signal, based on which the protection func-
tions can recognize that the automatic reclosing function only occurs after 1-pole tripping (
AR only after
1p. trip
). The approval or switch over of special protection stages only occurs for types of faults that lead to
1-pole tripping.

The cycle control checks the availability for each automatic reclosing cycle. In Figure 6-304, the cycle control

cycles are generally described with the cycle number n and apply for all other configured automatic reclosing
cycles.
