This is a Paul Saw,pop-up,used for flooring.Checked all cables.Did comissioning with batt box,I made.According to siemans install manual,Go board is bad,but I have replaced it three times,and symptoms are always the same.I am starting to suspect the No board,and if I could get the schematics,would have it nailed,but no dice on it,so far.If you have no motor motion,and no leds light,you have same problem I have.Best of luck.
