Hi guys,

I am working on a reasonably new Mx-Gc miconic schindler lift

I am having issues with the safety circuit 50vdc supply, as in there is no 50vdc supply to the start of the safety circuit.

I am also unable to find the power supply source.

Any help will be greaty appreciated.

Thanks

H,
On the prints are you able to trace the safety circuit back to the board on the controller? If so, can you see what wires supply that board?

Search for the safety-circuit in the schematics. It start on the left of the paper. ASIX-pcb.
