In DEIF standard libraries, voltage input 3 on the AX1 module in slot 1 is always reserved for analogue dimmer and
is not used as input for any of the virtual indicators.

*) The input is default set up to use a potentiometer connected to the Vref output on
AX1 module terminal 3, but it can easily be reconfigured to a dimmer voltage input instead.
The analogue dimmer value is shared on CAN for the actual dimmer group, and since the XDi 3 is part of group 1
(default), its dimmer level will be controlled from the XDi 2 via the XDi-net.
**) This will require an AX1 module mounted on the XDi 1 located in the ECR.
