Wondering if anyone has a set of schematics for an older Otis residential elevator. Not sure of the model, but it is a PLC-based controller. I have attached a picture of the controller
That's an esi controller. I think they called them Sysmacs. That's when Otis bought out cemco and ran them into the ground. I may have prints for them at the office. Are you having issues with it ? Or just trying to get a set?
Thanks for that information, I had no idea the history of them when it was installed. The car is running but has very intermittent issues but there isn't any information on site
