I have installed the EMS-2 connected to RDAC XG and I'm wondering how to properly connect the fuel level sender.

Engine: ROTAX 912
EMS-2 Analog Channel 4: MODE: "Fuel level"

Connection of sensors:
RPM -> RPM1 @RDAC
Current sensor -> Current @RDAC
OilP (4..20mA) -> OilP @RDAC
Oil Temp -> OilT @RDAC
CoolTemp -> AUX1 @RDAC
Fuel Level -> FL1 or AUX2 ???

Best to use FL1- that is its intended use.
Routing, signal conditioning, tank linearisation and display are all available to you by default using that input.

Hi Stuart,

thank you very much for the quick reply.
I had the same thought but the manual of the EMS-2 says that the analog channel 4 is mapped to aux2 of the RDAC. So how can the mapping be changed to FL1?

Select RDAC as the source for that channel- that way it will pick up the RDAC FL input.
The bits in the manual re analog channel setups mainly relate to using the direct analog inputs on the EMS2.
