Thanks for the reply Robert. The lift isn't on fire service. There is another lift (sorry I'm in England!!) with the same controller. I compared all inputs on the functioning logic board to the faulty one and they all match. The fact that the faulty lift logic board wouldn't allow me to cycle through the perameters i.e A,F,1,2 etc but the controller which is on service allows you to cycle the perameters lead me to suspect the board. Also the digital indicator shows "0" where it should and usually shows -1 which again leads me to suspect that perameters have been lost out of the board. Admin....I am a lift engineer working in England.
