trane ipc3 bus base on RS485

[guqunlin]

We have a RTAC-200 Trane air cooling chiller , but now it's pressure transmitter manufacture by Danfoss can't communicated with CH530 controller ,thus one of compressor does't work .who know how to determine the transmitter good or damaged.it's type is AKS1008.output:IPC3 ,i exploring it on Danfoss website nothing.I check my service manual of Trane that all of sensor and transducer connected together through IPC3 bus base on RS485.

Do you have a laptop with Techview on it and can you communicate with the ch-530,you can check all the transducers and sensors thru Techview and check their bindings, you may just need to rebind the pressure transducer.

You need a laptop (as said) with the latest techview version and MP software for your machine. You need to go into binding view and check the status of the device. I recommend you at least call Trane on this one, watch what they do and then decide for yourself if you want to handle stuff like that from there. Things these days are getting more and more technical. It is getting harder and harder for the average guy to keep up without factory support. Working for Trane and even being a Field Tech Supervisor, I still have a hard time keeping up on everything, but TechView is one thing I latched onto (being a computer guru)

who have knowledge at the IPC3 protocol?and where can get the information about that?

Dude you're not going to hack into the ch-530 by knowing the IPC3 protocol, even if you had a flux capacitor and a kneuter valve actuator, it is all propietery gibberish in there. Besides that there is no need to hack into the damn thing the software is free. Just get a laptop, download Techview software from Trane.com and hook up and go, you are probably going to need a new transducer, install the transducer, rebind it and your done, whole job takes about 15 minutes tops.

we found the red power line broken when taken off the pressure transducer,so we welding it and install on it again,but more different failure alarm occured.actually that's ok.what's the reson,the transmitter be damaged?

Buddy....I go on a lot of service calls after folks like you have performed southern engineering. My advice; CALL A QUALIFIED TRANE TECH. ONCE HE SHOWS UP, WORK WITH HIM, AND LEARN HOW ITS FIXED. The next time you won't be shooting in the dark. Stop where you are before you make the problem worse. Its a simple fix (one way or another), so don't turn it into a cluster.

I think we've been had here, by Eddy or Gruvn or some other troll, oh well I'm sure it wont be the last time.
