Having issues with two cars that are six weeks away from modernization. I have yet to observe the issues either car has, but apparently passengers are trapped on almost a daily basis. I babysat the cars for a few hours and didn’t see anything out of the ordinary. I am missing at least half of the wiring diagrams.

As the thread title suggests, this is 20 stop duplex of US Elevators installed in 1981. I was unable to locate a model of the controller anywhere on the controller or the print pages I have. The job has motor generators, geared machines, 20 front openings and emergency power.

I have included a few photos. Any help with prints would be greatly appreciated.
