Page 1 of 2 1 2 Last Jump to page: Results 1 to 13 of Thread: trane cvhf centrifugal chiller sensor calibration. Thread Tools Show Printable Version. If its a UCP2 control, the differential between transducers can not be adjusted. I think can't remember the max diffential is 2 psid. Above that and the chiller will lock out.
I actually had one case where the transducers were fine, but the input on the board was bad and I had to replace the board. Easiest way to determine is swap inputs when chiller is off and make sure the readings cary over to the other input. Unually though one of the transducers is the problem. Don't overlook the oil filter or the fact that the sensors could be doing what they are suppose to, shut machine down to protect compressor. I've even had a few where the reason the pump assy was hard to turn was due to copper plating.
All my leon freaked out! When the diagnostic says "differential pressure transducer calibration" the UCP2 is trying to tell you the transducers are not reading equal when the machine is equalized. Any oil pump "drag" on a CVHF chiller will result in a blown fuse. You need to read my previous post which explains what to check. C'mon Scott, lighten up. Over the years, be it good or be it bad I've gotten in the habbit of keeping my options open.
After going through the original guestion a little more thoroughly I see now that my tangent was getting into a different subject. BTW, can you tell us how to calibrate the transducers? Just kidding!!!!Remember Me? Page 1 of 2 1 2 Last Jump to page: Results 1 to 13 of Thread Tools Show Printable Version. If someone tried to shortcut by skipping these two steps, and the replacement drier is swiftly swapped into place, how much refrigerant would be lost?
Is it significant? Is a special pump needed for steps 3 and 4? I'm concerned a typical vacuum pump might discharge too much oil. Originally Posted by ra. Why take a shortcut on this? Originally Posted by heavymetaldad.

Whadaya gonna save? Getting back to the original post questions. First, you most likely will have enough residual to set a quality, calibrated refrigerant monitor into alarm.
How much time do you think you're going to save taking shortcuts when you've got five to do? What kind of a vacuum pump do you use? Mine sure doesn't spew oil all over the place. The procedure cooolguy uses,is the same procedure I use. I will leave the gauge on for 1 or 2 hours, when I"m doing my maintenance. To make sure there is no leaks.

Then I checked it with the chiller off again and I have 30 psi. Anybody have any thoughts on this? Oil filter is new. Yes it has a regulator. I am not aware of a cleaning procedure. NZ All Blacks Fan said:. Oil pressure with the machine down? You mean with the machine off and the oil pump running? Sent from my iPhone using Tapatalk. Seacurrent said:. Actually, I didn't get back to the job until yesterday and the problem has mysteriously disappeared. So I'm gonna assume that maybe some small debris was interfering with the regulator.
I will keep an eye on it and hope that's the end of it. There are 3 chillers here and they only need to run 1 at any given time except on the hottest days of summer when occasionally another one will start so there is plenty of redundancy. You must log in or register to reply here.
