The dropout delay only operates if no inrush was detected. An incoming inrush will reset a running dropout
delay time.
If parameter MANUAL CLOSE is set to 50 -1 instant. and manual close detection is used, a pickup causes
instantaneous tripping, even if blocking of the element via binary input is present. The same applies to 79AR
50-1 inst.
