Action Time

If the automatic reclosing function is in the idle state automatic reclosing function ready, an incoming
general pickup will affect the start of the action time. This applies for the reclosing function cycles that are
released through the parameter 

Start from idle state allow.

 and not blocked.

During one of the started action times, the corresponding reclosing cycle is blocked and the reclosing cycle is
assigned the next highest cycle number, whose action time is running and is not blocked.
With raising trip commands, the action times are stopped and reset. The process state of the action times
existing at this moment determines the automatic reclosing cycle that should be started.
If all initiated action times expire without capturing a tripping, the automatic reclosing function does not take
place. However, if a tripping function is initiated after expiry of the action time, the automatic closing function
is blocked for 3 seconds. A new start of the reclosing function is only possible if the general pickup is no longer
active.
