With the parameter Pickup delay you set whether pickup of the stage is to be delayed or not. If the tran-
sient cycle of the ground fault occurrence should not be evaluated, set a delay of 100 ms, for example.
Parameter: Operate delay
•
Default setting (_:6) Operate delay = 0.30 s
The Operate delay parameter determines the time during which the pickup conditions must be met to
issue the operate indication. The operate indication is issued when this time expires.
