Home Forums General Discussion Technical Questions Otis pie plate selector

Looking for some help on why the LV ring won't drop coming into the 1st landing after taking a 1U hall call. The LV ring drops off of a 1C car call. Looks like the car stops off the bottom directional and relevels back up. I don't have any info on the stopping sequence for these pie plate selectors. I appreciate any help.

What controller isrunning this 6850 selector?
Is it stopping on the directional of hoistway or selector?
How many stops?
Geared?

It is a geared 5 stop with a 10UCL controller. The car is not dropping the LV ring while running down to answer a up hall call. All other call selections seem to be working properly.

Found the problem in the hook circuit shorting bar.

Well done.
