I think what you mean is that the load relay is an active ON relay, meaning Load relay is closed when Load should be ON. (Which is how I am using it).
This is what I have assumed - Normally Closed Generator relay is closed when SCC is off or whenever Vbat is > Vuvw.
Once Vbat drops below Vuvw, that Normally Closed Generator Relay opens and once open, it remains open until Vbat charges to above Vuvwr
I appreciate that you’ve confirmed my reading of the generator relay function is correct. I am suspecting my issue may be related to not understanding whether ‘OilEngine_controlsignal’ must be Enabled for generator relay to function as well as whether changes to Vuvw and Vuvwr take immediate effect or not.
Some changes to settings apparently only take effect overnight and/or after charging state has changed…
