cvhf910 ch530 problem

[mustardman]

Went to a site today to do the winter maintenance on a couple of chillers and found both chillers the hour and start meters have zeroed themselves along with the purge minutes. The customer had a power bump a week ago but other than that there has been power applied to these chillers ever since start up except for servicing not that that matters. I hooked up my laptop and still reads 0. I checked for settings that allow zeroing etc I got nothing . I am stumped. I am waiting for a response from tech support but as it was late in the day I expect to hear from them tommorrow. Any ideas guys?????

from CTV-SVB31B-EN:

"Problem 1): MEMORY LOSS: This software contained a flaw that caused a
sector of the memory to be written excessively. This action caused a portion of the EEPROM memory to become corrupted. Once corrupted the failure
surfaces each time a power interruption occurs (greater than a couple of seconds) causing the data in EEPROM to be recalled to active memory. The corrupted portion of the memory includes the starts and hours count (set to zero), the historic diagnostics (lost), and Setpoints (set to default levels). The unit will restart and run with the default Setpoint values, however, they will need to be re-entered as necessary.

Problem 1 is addressed with version CTV 9.0. (This version CTV 9.0 does not
fully address problem 2 below)"

basically...upgrade the software.
of course, by now the software version is up to 10.02

there is a confidential service bulletin (i can't publish anything about that!). what serial number do you have? they list the units that need to be upgraded.

good luck.

Jayguy thanks I can't access my trane acct for some reason it isn't working for me.

Let me edit my info in my profile to include my email. Would you mind sending it to me I would really appreciate it. I am 8 hrs from home on a holiday and no one from my office is answering. While I am at it can I reset the hours and starts to what they were at my last inspection? I haven't looked at that yet bit of an afterthought. A simple yes or no will do on that one I can figure out the rest. Thanks

Yes you can edit the hrs in the newer software . Graham. good luck

If you are a trane tech, Take a look on the back page of the Sept/Oct 2008 technician newsletter.

I don't understand why you guys get on here & talk in riddles.

Wouldn't it be easier just to call each other? Afterall, the riddles don't help the rest of us dum dums. But, they are occasionally entertaining.

For the record, I'm not a Trane tech, but I want to know whats on the back of the news letter.

[Healey Nut]

SssssssHhhhhhhhhhhhhhhhhhh. your not suppost to give away the new corporate handshake or tell anyone about the new tattoo we all have to get . Its meant to be a secret shhhhhhhhhhhhhssssssssssss dont tell ??????????

Will do as soon as I get home I am 8 hrs from there right now. An hour or so I after my last post got on to the portal and got everything I needed all is better now. Thanks everyone for there help as always it is much appreciated.

[jimbob73]

chiller mekanik, Because there are people on here with too low of a post count that could do harm to themselves and others if they had the info

I'm being sarcastic, Due to some of the stuff I've been reading around this place. As long as I post a hundred topics in the funny forum, Then ask one question for info, I guess I would have earned the right to get it. But if I have 30 years experience and have 2 posts and ask for info, I'm SOL!

You were on a job 8 hours from home?

[mustardman]

You betcha our territory is huge main office out of Vancouver BC but I work in the interior out of the Kelowna office. I go as far as a town called Dawson Creek its about 1100 kms from my place in Vernon. Google it. BC is very big. A lot of windshield time because our towns are very spread out and none of them are big enough to support a guy full time. I am in Prince George in my hotel as we speak about 750 kms from my front door. I am on the road 1-2 weeks a month year round but its not too bad the more time I am away from home the less chance I have of ticking off the wife.

[jimbob73]

Geesh, In the midwest, USA, There are Trane offices all over the place so a job 3 hours away is considered a haul.

[mustardman]

It used to be like that for me prior to transferring from the Vancouver office but now I am just glad I don't pay the fuel bill. The only real downside is you have to quadruple check everything before you head out nothing worse than forgetting a part only to discover it when you get to site around 10pm or something. Not that that has ever happenend to me

[jimbob73]

You are one dedicated Trane citizen!

I hear you loud & clear. I spend time myself wondering about the ill effects from some of the information we post on here when it gets in the wrong hands; ie, people without the proper experience.

No doubt there have been times people have read something on this web site & went to work the next day claiming to have a "revelation" and now they know what to do to fix the problem. I'm sure there have also been occasions when someone has misapplied something read here only to compound the problem & likely cost someone some money.

That being said, as we (pro's) help each other out from time to time, you have to wonder how much injustice we do when our posts are read by incompetant people.

I know you guys are factory & I have no problem with that & I'm sure you know by now I'm independent (always have been) & I have no doubt that you don't have any problems with truly competant independents.

For instance, a Trane tech may have plenty of information that he would like to gaurd for a variety of reasons. But, if your on a forum & someone in another part of the country needs help & you are confident that this person knows what he is doing, you would probably be inclined to help.

There could be a day that you wind up in front of a Carrier machine & who knows, maybe one of the lowly independents could possibly be able to help you out. It would be no different than a Trane tech giving specific info to a McQuay tech that is working on a Trane chiller. Unless of course all of the factory guys on here have a problem with independents. But in all honesty, I would be suprised if that was the case.

I know this has been kicked around before, but maybe its time we start another thread to see what kind of support we could scrounge up & really think about approaching the Moderators to consider a forum just for chillers mechanics. How would we determine elegibility? I'm not completely sure but, one thing that comes to mind is maybe there could be a committee that could vote on membership requests. Or, we band together & come up with a reasonable list of requirements that mods would ask people to produce when they request clearance for the "chiller" forum.

Maybe we would even want to consider operators participation if they have the appropiate skill sets. Now, before any of the competant operators get offended, I'm not talking about excluding you. I'm talking about excluding the guys that don't approach from delta T.

Another idea is that apprentices could possibly join if a member in their area recommends them.

I suppose this could be a pipe dream. But, if anyone thinks its a good idea, lets start another thread & see where it goes. If we get enough support, maybe the Mods would consider it.

One more thing, I know one of you guys can tell us whats on that news letter. C'mon, share a little gossip. (unles it really is boring)

[hvacowboy]

I could tell you, but then I would have to kill you.


It just says to use CTV MP Ver 10.0 instead of 10.02 due to some bug.

Pretty cool huh.

Bug, What bug? I was referring to the right gloves for the job part.

[acjourneyman]

I overhauled a sidewinder in Prince George with the Jer and did the controls upgrades on the chillers at the university.

[mustardman]

I will guess the sidewinder you refer to is the canada trust building with good ol Bob as the operator. I think thats the only one. What University the college of new cal or UNBC cause if its the latter thats where I was having my problem hauled that old absorber out of there a few years ago and put in 2 CVHF 910's. Time for another retro fit on the controls at new cal I think it will soon be CH 531 happening in there. Lots of machines up here are needing to be upgraded I think we are going to overhaul the PCV at the hospital just waiting for a PO. I think I will be spending a lot of time up here over the winter.

[acjourneyman]

Yes, it was the bank and the upgrade was the PCM's on UNBC.
