greenspun.com : LUSENET : Elevator Problem Discussion : One Thread

I just got quite a few of these on service and MP 1210s Circa. 1981. Any good stories,common problems,anything to share? I Enjoyed the Flamingo and San diego stories about the first ones to be installed.Mine use the CPS or optical car positioning sencore.

I have never had one on service but have some of the manuals and allways found them interesting, last one I saw was installed new in Salt Lake about 1991 and it had a Ip8300 tape selector, GE Gearless machines and Gen and the tape was noisey in the hatch at high speed.The consultants would joke after the cars were done they would say Ok now they are ready for modernization. You could get those with gen or static drives. I once visited the US Spring Valley plant in 1980 and saw the wave soldering machine for PC boards and they made them right there, had cards made but loaded them and tested in house. That optical selector is a sheetmetal box that sits on the machine??? 1200 were gearless and the 1210 were geared.They were charging $1000 per car for service 20 years ago because no one else would touch that stuff. See consultants are not so bad because they would never approve those controls. How are your running and can you still get boards, and have you copied all your software.

Im not sure if MP 1210 had wire wrapped boards, but we had some US controllers on service that did. They were so problemmatic that they were replaced within 6 years of installiation. Let me know if you need some parts/boards, Ive got a triplex system in my warehouse.

I will pray for you tomarrow at mass.

Hi Joe, I cut my teeth on US 1200, 1210, 1220, and 1230. They just replaced the last 1200 in town, Years ago one of those elevators lost the power board in the SCR drive. The brake picked and the car went from the 9th floor to the 19th floor very, very, very fast. When I opened the bottom hoistway door. The comp sheave was tore out of the floor and hanging two floors up.It took a repair crew a whole week to get the car back in service. If you have any questions I'll try to help.
