I'm trying to configure load shedding using relay assistants for AC-Out-2 on a 3-phase Quattro-II system. AC-Out-2 shall be dropped on all three phases/Quattros as soon as a device goes into an overload alarm or when a pre-alarm exists for several seconds.
For this I configured the wizards shown in the screenshot. However, a test with Overload Pre-Alarm on one phase did not drop AC-Out-2 of all or even the affected phase.
What am I doing wrong?
Many thanks in advance!
