Hi People
Late 1950's Otis 6850 selector and controller ( 6164 relays ) Duplex pair of gen set lifts, 1 lift crash stopping between floors, both up and down. the main lift is running AOK
Will drive off XU or XD but will crash stop imediately instead of going to the next floor when the relay is released, and will respond to a landing call to a floor but will crash stop about 3 feet short every time.
levelling ring , is also obviously between between ramps/ LV cams, and all contacts are clear of the LV ramps in travel.
Wish I was a good enough engineer to get through this one which is probably very basic.
Also in the same mode... can any one send me a very basic relay operating sequence so that I know what is supposed to be occuring when all is well with this type of controller
Any help would be appreciated
many thanks
