Anyone have an adjustors manual or any other info on the Otis MRS? We have one down right now that just keeps running between the upper/lower limits. Replaced the stepper board with no change.

I'll bet there's a problem in the leveling unit..

Is it counting. Do the LR relays count. May have a dz sensor bad. Does it have BCO and TCO relays. They are switches on the limit trees. They have to make up at terminal floors also. If it's making and breaking it will turn around and do a correction run constantly.

I had my tech check the leveling relays; they are all picking and dropping properly. He already replaced the BCO and TCO relays. He also tried the new stepper board in an adjacent car, and it worked fine. However, in the other car that's down, the board isn't stepping up or down with the car.

Found the issue... bad ice cube relay. Thanks for the help, though.
