we were hired to repair and Otis Elevonic 411 RM Regent Control that was used on a Modernization project about 10 years ago. The controller completely when on fire. Otis, Thyssen, other medium size Companies were not interested in repairing the elevator, they just wanted to Modernize. We are a small independent Company a accepted the challenge. Actually the elevator is running almost perfect. The only problem that it makes (not always) is that when the car is in the down direction and goes thru floor 18 it suddenly lost it self, make a sudden stop and goes back up to the 18 floor several times looking for orientation or for goes directly to the last landing looking for orientation in the hoistway. We have Otis Service Tool, we have diagrams for this equipment, we have manuals control and drive unit Model OVF-30, its a DC drive with SCR and a DC motor. We have check the hoistway vanes, the inductors over the cabin, gone thru the manual. And this has been frustrating. Lately we found out that the elevator was not balanced, apparently somebody took some weights from that elevator to use them in another one. After we installed the weight on the counterweight was needed to balance the elevator (Static Balance). The elevator commenced to work perfectly well for 2 days and then he go back to the same thing. Then we put apprx 276lbs of weight on the top of the cabin that we too of from the counterweight and is working better but eventually do the same thing. WE do the shaft learning with the Service Tool and works ok for a while. We need someone very knowledgeable of this kind of equipment to assist us solving this problem. You help will be appreciated and remunerated if needed. Wait for your reply. Thanks.

Couple of months down the road, this car has a hiccup, stops in flight, mis-levels, passenger trips, breaks a bone, sues for disability, lawyer finds out the controller burned, also finds out 2 major companies including the manufacture wanted to mod, you and the owner pay a lot of money to the passenger.
Smaller companies love to bash the big boys for trying to "take advantage" of customers but this is what the majors have to think about. I have had multiple instances of this type of situation happening. One of them seriously injured a passenger which resulted in a huge lawsuit. If you don't know what you are doing please don't put the public at risk, it's bad for the whole industry.
