From the distance it's impossible to find out what's wrong. But the A-111
cannot be damaged by a "wrong" CV coming from the bus access module. It will
withstand any CV in the range -12V...+12V and the bus access module cannot
generate a voltage beyond these values. If you cannot find the fault please
follow the repair notes on the FAQ page of our website:
