That's an Omron controller. Parts and pieces are still available for them. A company here in Florida named Mowrey installed units similar to that about 25 years ago.
It's a Cemco Controller. Otis Elevator had a residential division selling these controls. Processor is no longer made. You can still find them on EBAY. Custom Elevator now supports the old CEMCO stuff.
You have a old Mowrey E.M.A.C. Sysmac C20. If you have issues with it most of the time it due to the battery inside the controller - I recommend replacement every 5 years to avoid any problems. They're reliable but can be a pain to work troubleshoot
Jim was kind enough to take the initiative to post this controller on my behalf. Thank you Jim. I'm looking for a set of prints for this controller. We had a few issues that would have benefited from the use of a print.
The fact the lady who uses the lift is SO sweet makes me want to continue keeping her lift in service...
J. I have some of Mowreys prints, but none of them have the same terminal markings.
