There was initially some difficulty adapting the FDS dimmer board for use with genuine Airbus pots. The Airbus pots were higher rated and connecting directly to the board would limit the range of the backlight – when the pot was at its minimum the backlight on panels would still be on.
The original solution substituted the Airbus genuine parts with pots compatible with the board. This was a working solution, but required disassembly and replacing the pot mechanism.
After discussing with David (electronic wiz) we now have a compatible solution which can work with existing genuine Airbus pots .
Simply replace the C1 capacitor (68 nF) with a 6.8 nF capacitor on the FDS dimmer board, connect the original pot and all should be working as intended.
