ifrratedpilot- We have been spinning the washers, making sure the mechanical brake release linkage is having no effect on the brake when it is set. We went so far as to take the actuating arms off the brake entirely, (washers spinning freely)just to completely rule that out!
While the eBrake set time should be low, to prevent heating of the ebrake coil/armature, it cannot be a substitute for the main brake not setting properly, or a problem with load weighing, resolver angle, etc. But yes, we lowered the eBrake set time to 3 seconds. IIRC, that is the lowest time that can be set with that parameter, so it would not help to catch the car on the initial stop. Therefore, the eBrake cannot remedy this issue, right?
The car is rolling upward, during main brake set. By the time the brake "catches" the car, it has rolled upward far enough for 61U to go dark, initiating down re-level. (I still like to think of it as old-school "LD" going high!)
I'm not sure what other people mean when they say the terms "rollback" and "rollforward", but this car "ROLLS UP", before the main brake catches the car. When I was at Otis, we called this "rollback".
theshaft, We will check your suggestions tomorrow,
Thank you everyone very much for your input, it is sincerely appreciated.
i'll put another call in to my Kone Guru, see what he says...
