Current Shunt relay logic not activating

I cannot seem to trigger the relay. See screenshot for configuration which i believe should be triggering at least three limits. 2023-04-02-123451_1920x2160_scrot

I'm not sure about using zeros in settings for the relay.

Are you using the latest firmware on the shunt board?

Changed zeros to 0.1 and -0.1, same result. Firmware version 40792eb5 dated 25 Jan 2023.

Ok, needs to be investigated more thoroughly, but I'm not near a computer for a few days now.

Just for information, what are you running from the shunt relay?

Thanks for looking into it! The shunt relay will initiate a generator start, triggered by the under voltage limit.

Ok, don't forget the relays on the controller can also do that for you!

Controller relays are assigned to Charge Permissive, Discharge Permissive, Non-critical Load Shed & Battery Heater. It seems the more output channels you provide, the more applications we dream up! Lol
