Otis Gamma 160 AC Drive problem

Guest · 2010-12-03T04:33:00Z

I have 2 of these on my route. One is a freight that is hardly used and the other is a passenger. Both identical geared machines with disc brakes. The passenger blows one of its main fuses about every 3-4 months. ($350 fuse) When it happens the car is always found about a foot above the top floor. We have routined all connections in the controller and swapped around the arrangement of the heat sinks mounted in the top of the controller. It has not blown the fuse since. My next problem is that every time you cycle the main line power the elevator instantly tries to run. If the power is cycled with the elevator at the top landing it will put itself into the overhead. Any ideas would be very helpful. Thanks from your IUEC brother.

Nice. We just walked out with them too lol. The place was abandoned but they only needed one running so we took what we could and still made a pretty penny on the maintenance contract.

MRVF had alot of these babies. Batteries to run an elevator. wow. They ran good for me though once i changed the selector and learned to keep the load weighing adjusted properly. Usually only one or two calls a year 🙂
