The alarm light on the power input unit trips if I plug in the white plug on the stabilization board, CP35, or if I hook up either 24v terminals going to the connection unit boards down below. It will stay on with everything other than those connected. I'm not sure what steps to take next as the manual I'm looking at doesn't really go very far in troubleshooting the alarm light on the input board; only shows where to check the voltages. Screen on control unit is turning on now, showing error 902 (Fault in bubble device - Page size error, undefined command) though I think that's probably because I don't have power to everything right now. I'm not sure that the problem is with the power supply at this point. Any advice?
