I'm trying to realise a two-phase load shedding functionality for overload situations. It should work as follows:
- Turn AC-Out-2 off when a Pre-Alarm exists for at least 2 seconds
- Turn AC-Out-2 back on 60 seconds after Pre-Alarm has been cleared
- Turn Primary Programmable Relay on as soon as a Pre-Alarm occurs
- Turn Primary Programmable Relay off 300 seconds after Pre-Alarm has beed cleared
Assistants 1. and 3. seem to work as expected, but 2. and 4. are executed way before the configured timeouts of 60 and 300 seconds.
I'm very grateful for any suggestions!
