I have an Otis Elevonic-R controller that is giving me fits trying to figure out what it is doing. Only in the down direction this car will come into slowdown at the landing, stop about an inch above, open the door and level into the landing. While watching the OCSS on the handheld it show NAV when this takes place. It would appear that I am losing my MCSS but I am not sure where or how. I have watched the MCSS status and one thing I notice is that I never get the FIN input. This also only seems to occur on a multi floor run. It doesn't seem to do this on a one floor run. Thanks for all your help.
