Bucher Valve

We have been installing these new valves for the past year or so. Its a pretty cool concept but I am a little skeptical with the claims that oil temp doesn't effect these things. Also, making adjustments to these valves without the HHT is a pretty big pain considering how small the buttons and screen are on the miniterminal.
The ride also seems inconsistent. coming in nice into the floor one minute and then overshooting and releveling the next. Maybe these are just growing pains. What do you guys think?

Get the cable from Bucher and download the iWIN software, you will get a much better overview on your laptop.

I've seen some problems on that valve already. Had to rebuild. Not sure about the longevity of it though.

The zero point is pretty critical on these

But as Alex says get the iWin software for a better view

I'll try it.

zero point is very important (Thyssenkrap)
is it a old controller controller ? bad contact high/lowspeed up/down contactor (because its now a input and low consumption coils!!)

Yeap, zero point its the first and very important way to start, remember close the shut off valve to adjust.

TKE using these now Have only seen 8 units so far but allready 2 of them have a vibration in the up acc and dec. other offices have seen this as well. No answers from the factory so far. I believe the bypass piston is sticking or shuttering as it closes and opens but not allowed to open valve and look. Anyone solve this ? I did find that getting the oil temp above 100 f helps. Wondering if Enviromax oil plays a part

Pour 4 qts of Maxton "Maxglide" additive in the tank, rub some on the piston's it will go away for about a yr, then will have to be done again. Don't use CAT additive Use maxglide

Don't use any additive with these units as it will coat the resistor in the valve and cause problems

Check your gain adjustment thru IMS and valve adjustments?

A couple I have were Cavetating and had to add a bucket of oil,they create a vortex and once in a while would growl at the top floor.
