Dover Composite Overshooting Floors

I have a Composite that is overshooting floors. Any suggestions on where to start?

How much is it overshooting? both directions?? Stopping sequence ISL, LU or LD, 2LR RTT(not dropping) RE 14 & 15 contactors working (core pin not loose)

I recently had a 7 stop overshooting floors in both directions at all stops but top ,bottom , and 4th floor. I checked everything having to do with compounding and I thought I had checked everything having to do with selector. I checked pie plates, cable, bearings, sensors, etc and everything seemed fine. I finally realized the set screws at the end of the shaft with the pie plates were loose on the opposite end from the drum and the whole shaft had shifted maybe 3/16’s of an inch. Why it didn’t effect floors 1,4,and 6 was kind of misleading

1,4and7

If overshooting both directions, is CLC pulling in at the end of run?

Just a note about Stuthers-Dunn relays ....14 15...armature pins are known to break. Relay appears to work but contacts do not make or break.

Slack in your selector cable

Yep. Tighten it up on the cartop

Also make sure you have plenty of spring tension on the selector cable under the car. 14 and 15 are crucial!
