I have these two Armour Dynaglides,maybe a prototype.

No car top selector,it gets a slowdown 24 in from the floor and does a binary countdown to the floor.

The issue I'm having with one of them is basically when it stops,the brake should drop and hold first before the contactor drops.
This is not happening,instead everything drops at the same time causing a very hard stop.
There are adjustments for the decel,curve and final speed.
I have tweeked these till I basically have no curve and a very slow final speed and it still does it.

Any ideas?
