Mr Rauf, No offense but I suggest you would be best served by engaging a service company in your area that are familiar with this type of equipment and the work you are requesting guidance for.
I want to replace the LCD/Display, can any one guide me how to replace the LCD display and how to re install the TECH VIEW and Dyna view CH 530?
dear i want to replace the LCD display of rtac chiller how can install the dyna view and tech view ch530 and how can save the old set points please tell me all procedure thanks for your nice cooperation.
thanks for advise to all
I like to use a tool already in my bag- a magnet on a telescoping handle, used for picking up small, dropped items. The wrong end is sticking out, but all I have to do is hold it sideways with the correct end near the LLID switch. It is all metal so I don't hold closer than an inch or two. It has never failed, and has never lit up a neighboring LLID.
Any magnet will work. If its to large you may light up more LED's than you want since some of the LLID's are small and mounted close together. I keep a small magnet I use to check smoke detectors stuck to the back door of my van so its easy to find.
yes Trane does sell a pocket size south pole magnet, happy holidays.
Good thread
You can use any south pole magnet. You can use any screwdriver with a magnet on the back and if it's in backwards, yank it out with pliers and put it in the other way.
please tell me south pole magnetic screwdriver this is special made by trane or we can use any piece of south pole magnetic for slecting the device .

Big Thankyou to "Screwit"for advice and resource info. socorrobob You shouldn't have to "await" TechView software as it's a free download at Trane.com. http://www.trane.com/COMMERCIAL/Desi...ew.aspx?i=1435 You can download the software, buy a standard 9 pin male X female serial cable, and read the bulletin that screwit posted.

You need to connect with TechView software to diagnose correctly. MP is the CH530 microprocessor, all the CH530 LLIDS (Low Level Inteligent Devices)/sensors, transducers, I/O boards, EXV,s etc connect to the MP via a comms bus. Functional ID and node number is assigned to the devices during binding (TechView process for connection to the comms bus). Functional ID is identification of the LLID, e.g Suction Pressure Transducer CPSR 2A. The attached link to Trane.com will provide some reading for a better explanation and guidance on troubleshooting http://www.trane.com/Commercial/Uplo...a-en-final.pdf

I'm going back Monday and demanding a refund They sucked you in too ???? Dont forget to take the Tartan paint back as well !!!!! And ask for the long stand while your at the counter .
So does that mean the east/west pole magnetic screwdriver I went out and bought for UCP2 work was a waste of time - I'm going back Monday and demanding a refund
On ucp2, no binding. On CH530 you'll always have to bind in the new device.
every time temp or pressure sensor is found faulty and replaced, need to rebind? only on ucp2 and 530?? Yeah but when you do UCP2 you need an east/west pole magnetic screwdriver

Then you replace that sensor with a neuron I.D. that's 200, the machine is still looking for I.D. 100 as the oil temp. sensor. It can not be cycled or reset to pick this new sensor up, as it will show a comm. loss with oil temp. sensor. But you have to do the steps that R123 stated. every time temp or pressure sensor is found faulty and replaced, need to rebind? only on ucp2 and 530??
