I have replaced the MCB board again. I have found if I plug in the om3, or om4 the bufers will heat up rapidly. Remember I have NO functions at all. I am not blowing any fuses, and all power supply are correct. The doors have no power. I have no lights when any buttons are pushed. No inspection movement. Nothing. I did find out that the building loss power to activate this. Lightning?.
I am on the track of bad software. We are looking for software now.
