Need help with a MCE-1000 CL w/Sweo SCR. Car shut down on 2nd landing with doors closed. Immediately I notice the processor has high speed output and the VVC drive unit is getting the HIGH input and the SCR interface has a run input and the Sweo drive is ready. Diagnostics show a btm and top flr demand and then the motor limit timer fault when on normal operation. The 2A flag show DMU and DMD flashing. Saf and Dz relays are good. Doors closed and locked. Checked U1 and D1 relays on MR insp then noticed that the run input on the interface dropped out but the processor and VVC stayed high. The guys at tech support suggested that the ripple voltage from the power supply to the processor might cause faulty outputs. However, the other 2 elevators in the group have the exact same peak voltage. Any suggestions? Its personal when a elevator kicks my ass on a friday
