Ekrano + Multiplus w/VE Transfer Switch( Utility and generator )

I have a Multiplus II 3000 with essentially a Victron VE transfer switch( I built it myself ), that controls switching the single input to the inverter to either Utility or Generator.

The transfer switch has a NO/NC contact that can be used to determine if the generator is running( and therefore triggered the switch of the inputs from Utility to Generator ), and I wanted to hook that up to relay 2 on the Ekrano.

I also want to do auto start/stop for the generator and wanted to hook that up to the Ekrano Relay 1, that part is well documented.

How can I configure the Ekrano to use Relay 2 to determine if I am connected to Shore Power( Utility ) or Generator?

Thanks,
Todd
