Programmable relay - AC input

Hi. I am trying to use the relay K2 to drive a contactor based on SOC. I would like the relay to also switch on based on any AC input but it isn't switching on when AC is available and the SOC is below 80%. It will only switch on when the battery has charged to 80%.

I struggle with the AND and OR logic also.

Can you make 2 Assistants (1 switch on at AC, 1 switch on at SOC)

Hi Harold. I have tried that but the switch relay off assistant seems to take preference over the switch relay on. I put the switch relay on when any AC input is detected at the top of the list but still doesn't work.

Also have a look at the Generator Auto start Assistant. This may be easyer to use for SOC and has a lot of other options.

you could also still use the other assistants in order

I am referring to use this to turn the relay k2 off and on under SOC conditions.
