20 years ago this was our everyday world. You have to play detective and eliminate problem areas from your thinking one by one. A lot of times when a Dover was stuck at a floor it would be from what we called a CS lockup. The CS relay should pulse in and out, but things like a door lock bouncing would cause it to pull in and stay energized. You may want to look at that circuit closely. Also if you have worn leveling rings on the selector it can create problems. A wire relay checker from SEES was also an invaluable tool for checking out Dover Relays. When you pull a relay out be sure to wiggle it from side to side and not up and down, this causes the base pins to get bent. Good Luck.

One other thought, a lot of times replacing the selector leveling board would be a place to start.

I once received a call for the elevator broke down at dusk. Of course they didn't want to pay for over time. The next morning we arrive and the elevator was running. At the end of the next day, (you guessed it) the elevator went down at dusk.
What we found was when the new outside lights went on at night, the voltage dropped enough to shut the elevator down.

Sometimes you have to look outside (no pun intended) of the elevator system.


Make good choices,

Floor level CS lockup is from a stuck button contact. CS lockup during a run is from worn selector guides.

It is sad when you think about it, this was our everyday at one time, has that much time passed??? It seems to have! The CS lockup, worn selector guides and slider switches, may want to check the selector "traveling cable", and of course those pesky IBM relays with the plastic coil liners that like to get brittle and brake, then the peices fall off into the relay contacts...

Hey you Guys your hurting my feelings by recommending a relay tester from SEEs. How bout WizBang Mark V designed and built by a fellow IUEC member?

I have the CS Lock-up band-aid if you want it

Work Safe,

Anyone have an idea where I can find a Dover Composite parts manual or parts list.

Is the car at floor level when you find it? Had one of these once that slipped traction on a zoning stop because brush did not provide enough slow down distance and CS lock-up occurred between floors.

I thing to try is rig MGT to not time out for trouble shooting purposes . Maybe MG set times out and doesn't restart. I believe the timer fires to time out MG set. Also 12A timer and auxiliaries on motor starting contactor if wye delta start. Sometimes all you have is process of elimination.

Does if have the rectangular black impulse push buttons with the metal mounting clips. If so, one of the instant door close contact may be bad on one of the buttons. If you put the car on independent service and the doors close without placing a call that will let you know for sure. Then remove the 305 from 1C button. If the doors reopen it's that button. If not reconnect the 305 wire on 1C and go to the next one until you find the bad one.
