If the problem persists let us know. I've seen and fixed this before.

Thanks, SteveO! It happened again!
These elevators are fairly new, about 6 or 7 years old. We've had them on service about two years, I think.
My associate thinks the oil is too cold. Because after running it for several runs, it then started stopping correctly. It has an oil cooler, and so he changed the thermostat setting today.
We had this problem a year ago, and when I reccomended a tank heater to the customer, he remarked that the two adjacent units had no problems, so why would this unit need one?
Interesting to note, that on the thrid unit in the same machine room, the OEM removed their own Hydro-Morris valve, and replaced it with a Maxton. That's very telling, when they change out their own installed brand of valve, for a Maxton.
Anyway, and ideas are sincerely appreciated!

I need to know how fast the car runs in order to set the slowdown magnets the correct distance from the floor. The distance is different between Maxton, Hydro Moris and OLS. The issue is that the floor table is flawed, just from my past experience. Do you know how to read the speed from the cpu? This will help when setting up the valve. Are you seeing any 153 errors? The software version in cpu will be of help also.

I like that idea, if it works, they pay, if it don't we pay. That's a good way to pitch it. it definately sounds like a cold oil problem. if it cures after a couple of runs this would indicate it. the viscosity of the oil when cold makes it thicker and therefore slightly harder for the up/dn valves to close over ergo the lift runs on a little. i would recommend you tell the customer that you try it and if it doesnt work then you will bear the cost, but if it does then they should apply these to both lifts at their cost. also remember it varies from block to block which may be the reason why its different on the other lift and wouldnt be surprised if it has a block heater in it. you should always have a block and oil heater as a base level for all hydros and and oil cooler for high traffic/temp areas. yeah vic i/we always try to look like we arent trying to rip customers off and by saying we will cover the cost if it doesnt work it shows this. i must admit ive never worked on a modern hydro without these block or oil heaters and this cold oil can also cause a relevel fault when the lift drops below level. very common fault that heater(and floor level tuning) can rectify.

Cool, I'm gonna use that approach. I like that idea, if it works, they pay, if it don't we pay.

Thanks, SteveO! Things are stable right now, it's been running for days. If we have to get back into it, I'll respond accordingly. Thanks for your input. I need to know how fast the car runs in order to set the slowdown magnets the correct distance from the floor. The distance is different between Maxton, Hydro Moris and OLS. The issue is that the floor table is flawed, just from my past experience. Do you know how to read the speed from the cpu? This will help when setting up the valve. Are you seeing any 153 errors?
