I have twin post 3stage telescoping jacks on a 150fpm car the job is a 3 stop fairly tall floors. The problem I have is the car has about 4 seconds of stabilized leveling running between floors 1 and 2 good but from Floors 2 to 3 that time increases to about 8. If I run the car from 1-3 I get 4 seconds of stabilized leveling. So for some reason on a One floor run from 2 to 3 my stabilized leveling time is increasing??? Any ideas what might cause this? I have looked for gaps on my slow down magnets they all look good?

Have you looked at what inputs are coming on in IMS when it gets to the long leveling?

hit the enter button too soon. Is it starting leveling at the same time on the one floor run and the two floor run, and just takes longer to get to the floor, or starting leveling at another spot in the shaft?

You aren’t getting up to full speed. Turn out on up start until you can feel the car get to high speed before the slowdown. Or confirm in IMS but pretty sure that’s all that’s going on.

Units 150 and over have emergency speed limiting In the top terminal floor. That explains the longer stabilized leveling.

No, then it would do it on a 1-3 run too. 2 to 3 must be a shorter floor.
