Cool, I'm gonna use that approach.

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.

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.

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.

Thanks, Dan. Yeah, you can nearly buy a whole new tank unit, for the money that it would cost to do it Kone's way. I know you change tanks out entirely, but have you ever managed to put your own "kit" together? I was looking at it, and it seemed kind of involved, so I thought this first time, we'd just go with the OEMs' method. New tank is at least $4.5k around these parts.

We buy whole new pump units and replace the whole thing for less money and time than Kones 16 pages of fix!! You need prints that show hook up for Maxton as the Hydro Morris is a 3 silonid set up.

I would also add you should always set the slow down magnet on a hydro slighty higher on the bottom floor than normal so you eliminate any problems of the lift going thru the overtravel limits when a temp problem occurs.

Never heard of that, thanks!

Before the advent of MRL lifts became prevelent here we installed roped hydro's as a standard lift. We found if you raise the bottom level slow down magnet on the rail by probably 50-100mm it really makes a difference when temp changes occur. The reason why this type of lift over runs, is the lift is not given enough time to slow and close the down valves in cold oil conditions. The passengers really cant tell the difference when slowing down and it seems to eradicate these temp variation overrun faults.

Vic we are doing one now at a hospital parking garage. Ordered a new pump unit from Minnisota Elevator for 2.8K and got it in less than a week. If we had not had to replace pump motors at least 3 times on these 2 units in the last 7 years I would of considered the OEMs fix. But when you can get rid of 2 problems at one time......

Cool fix. Cheaper than Kone plus you get a new motor and pump!

Check out their silence unit you may like it...

Good call Dan!

Sometimes you replace the entire pump unit, like Dan did with the hospital parking garage from Minnesota Elevator. Their silencer is an upgrade from the cosmetic chamber mufflers too. Save your labor time and replace, everyone's happy.

Gotta love a win win win...With this contract if parts are obsoleat the customer eats the material and we eat the labor so not too bad a trade off.
