Unfortunately, given the age of the chiller and intermittent issues, we opted to just replace the whole drive compartment. I would venture to say though, that given the intermittent issues, there is...

Well Chiller apparently tripped on the fault again this Saturday :/. That's weird that the problem is intermittent like that.

Thanks Jayguy! I think I might have resolved the issue by cleaning the connectors, as the chiller has been running fine for the past two weeks so far. If not, I am going to switch out the B pole on...

So no one has any idea as to what could be the problem?

I have four York YTG1A1C3-CKH chillers w/ York Turbo-Modulator Model #TM351T B6-46B VSD Drives in my building.

One of them I am having intermittent issues with when trying to start. Whenever I...

ph33r do you work for Cohesive Automation in Dallas?

I have DDC that is generic sent out to all my AHU's. Once I edit that DDC file can I send it to all my AHU's VLC devices or do I have to send...

I am trying to get AI5 on a VLC-651r device to a 10k thermistor setting. Currently AI5 on this specific device is set to "Counts".

Can I send the DDC to this specific device 2011074, without...

Jayguy, I checked over the control panel cabinet to see if they had made any changes, and it appeared to me that they hadn't. Unless it was a parameter setting, I think we still have a ghost in the...

Most people don't have chillers in their home they can tinker with :P

Screwit and jayguy - Trane had their big wig service guy come in today with the service supervisor and they got it running. ...

Got a control cabinet with an AFD TR-200 in it, just installed and Trane can't figure out why they keep getting a "Phase Loss" alarm from it. CT's and PT's have all been checked for Polarity (unsure...

Sounds like a rather large liability for the owner of the company you are working for.

I have been trying to connect to my CH530 via Trane TechView using a straight serial connection (not USB to Serial) on Com 2.

I cannot connect to it, gives me a communication failed error.

My suggestion would be to pony up the money for the ABS system. :.02:

Thanks for that info, it very well could have something to do with EMI, as I thought about this before, by running a new comm cable directly from chiller 2 to chiller 3 trying to eliminate this...

Need more info! :cheers:

All I know is you can use Envision on a laptop and stab directly into the BCM-WEB module, but I don't know the level of security your going to need to access the information you are wanting. (ie....

I'm not sure I understand your questions, but If I undertstand what you are saying, you need to get on the host server/computer that has envision installed on it at the site or you can use a program...

The transformer has no polarity. You can use either yellow or blue.

That's an interesting setup Rob. Never saw a chiller like that. Is that essentially two chillers connected as one? Curious to see the inside of something like that.

Do the tubes run the whole...

I would like to retract my statement about you having to have a contact or. If it is a small unit then there is no need for one.

Samsung! Do you know if the PS went out in it, the backlight circuitry, or the display board? I have fixed a few monitors for $.20 by replacing the bulging/bad caps in the PS board. When it comes...

Ya, I hope you are not pumping a scroll down to 0PSI :gah: Please do yourself a favor and call a pro or for help. If it is a scroll, you could be doing damage to the compressor.

You not having a...

Thanks for the info. I will certainly try one of these out!

Well... I got my laptop and seeing that it doesnt have a serial port I tried using an IOware USB-Serial connector with no luck. Guess I need to buy one that is known to work with the Tracer CH-530....

We have four total chillers.

This chiller in reference is a 120-ton Trane CVHE from 1984 with the big black box and the four vertical gauges on the left hand side kind of like the 800-ton Trane...

Nucl, I greatly appreciate all of your help. You have been a tremendous source of information in the matters that I haev brought forth.

Can someone please explain to me the operation of the purge unit. Still kind of new with chillers. I get what the purge's purpose is, but still have a few unanswered questions.

Does the Filter...

^ I concur

Here is our Comm4 Interface Card:

When switching to BAS/FP/EXT setpoint mode on the front panel @ 19:42pm this is the info I pulled from the chiller:

ASHRAE Diagnostic Log: 19:42pm BAS Communication Lost

Sequence of Events...

But my question would be to you... Why would one chiller continue to run when switched to BAS mode and the other not?

Ya q, that was the last option I had, but I would have to do some Visual Logic re-programming to tell the chiller to not use the external relay to start/stop the chiller but rather use the tracer...

This sounds like its going to turn out disastrous :P Please call a pro, and no, you cannot use plumbing solder

Trane is like the CIA of the HVAC world; They will only tell you so much (vague) information.

I called them up one day trying to get information about why our Tracer summit is kicking one of our...

Please disregard the Comm wiring diagram as it is incorrect.

Still can't figure out why my chiller, whether it's the lead or lag chiller, shutsdown. All wiring seems to be ok, and I verified it by running a new comm wire from chiller #2 to chiller #1

The...

I would also like a copy as well please :)

Airflow... hehehehe

We need a heck of a lot more info than what you are giving to help you properly diagnose the issue your are having.

Yes, there are manual valves on each side of each of the pumps. There are so many manual valves, it would be hard for me to identify them all lol.

The Bray Automatic Valves are located on each chillers, chilled water supply and condenser water return right at the chiller. There are no automatic valves yet on the chiller in the bold outline,...

The proposed chiller is in the bold outline on the plans and will have VFD's on both pumps and compressor:
You can right-click the image and save it to your computer, so that you can rotate it...

Sorry that was my mistake, we run the Tracer™ CH530 on the chillers and they use the UCP3 board. We also have a comm4 board in them for communication with the Tracer Summit BCU.

Russ, you state...

Our other chillers were put in in August of 2007, so they are fairly new. They are both CVHE 600-tons running ucp4

We are prepared to run everything at 60Hz, because even though we are only "operating engineers", we know what the effects of this new VFD Chiller and pumps is going to have on us. We are screaming...

I don't see why you couldn't change the port number

Going off of what phase loss said, just because all your fan blades are turning doesn't mean they are all operating. Also, is your condensate drain draining properly?

Another question is, Where are you taking your subcooling and superheat readings at? The compressor/condenser on the roof? You need to try and take the superheat reading from the evaporator and not...
