You might find the attached useful 850521

Been a while since I worked for Mother Trane or on RTHD, however pages 59-60 of the attached is a good guide 836138 also modifications for the original gas pump 836140

Champion, thanks for your efforts a real benefit to our industry and enjoy the next phase

Sounds like one of the LLIDS or even the field connector are dragging your comms bus down - suggest you divide and conquer (disconnect the comms bus runs until you can narrow down the fault)

If your looking for reading material you can find plenty from the Trane website...

In addition to compressor design/technology refrigerant type and improvements in heat exchange technology also significantly impacts on chiller footprint - even for the same refrigerant type when...

Balfe,

If it 2018 vintage will be PIC5, this has the smart password feature that changes every 3 months. The new password is distributed by email to an authorized distribution list.

Definitely, the mechanical design is fundamentally the same as for oil lubricated bearings. However, the reality due to the lower maximum rotational speed and characteristics of the ceramic bearings...

Suggest you might want look at your EXV module dip switch addressing - the attached set-up bulletin is circa 1997 but should help for ERTAA328.

Hi Manu,

Have not heard of Clarky for a few years now. Not sure what he is up to

Similar as far as back to back compressor concept, however 19DV is completely different design, capacity range and refrigerant compared to CVHS.

E in the serial # is for Europe, RTAC 275 from Charmes Factory. Almost identical design except for Electrical enclosure components and fans. Compressor comes out of the US, or is it Mexico now?

No problems, optimum level for each evaporator is set at 0", the CH530 should modulate the EXV to maintain the LLS around +0.1" when chiller operation has stabilized. The LLS is direct feedback of...

For falling film evaporators the liquid level sensor controls the pool of refrigerant/oil mix in the bottom of the evaporator by controlling the EXV position, maintaining a pool at an optimum level...

Damn, been in this game for coming up to 40 years now and survived to date without a fluggometer but looks like with this latest upgrade may have to relent now and get one

“The AdaptiView™TD7operator interface allows for daily operational tasks and setpoint changes. However, to adequately service the chiller Tracer™TU service tool is required. (Non-Trane personnel,...

The DynaView needs to be removed and the back cover unscrewed/removed to access for inspection of the battery clip.

MP Reset has occurred - " The main processor has successfully come out of a reset and built its application. A reset may havebeen due to a power up, installing new software orconfiguration. This...

And if it is broke...... fix the problem not the symptom - low oil level is a symptom of a problem in the machine or operation. While on the quotes don't add to the oil charge unless there is a pool...

Water is already a component of the POE lubricants used with HFC refrigerants so the addition of moisture results in the formation of the non-aggressive carboxylic acid (not hydrochloric as the case...

If the chiller has been idle for years following a tube failure could almost guarantee your compressor will be seized unless the system was dehydrated almost immediately after the failure.
...

Rtad uses the oil temp senser and saturated condenser temp sensor for oil protection. Both are direct emersion sensors so you need to isolate and recover refrigerant. Which fault are you seeing, it...

Serial No. A91D-0149 tells me it it a Trane Blacktown Australia Built Chiller (A direct replica of the LAX version). The Australian Plant shut down around 98. Sales Order # A0543-47 was installed in...

Data files are still stored when connected with TechView so can be imported and viewed in programs other than KestralView. Other key difference is pre-formatted service reports and help files

What MP version are you running? I would hold off on replacing a compressor and stater LLID just yet!

A picture is worth a thousand words

[QUOTE=valdelocc;17362481]Hilarius video, wonder if fellow site members were involved?:grin2:

Not going to be too hilarious if ever the 1st stage IGV need to come out again with all that loctite...

True providing you have sufficient heat energy for the phase change to occur and allow sufficient time.




This dependant purely dependant on how quickly the vapour pressure is acheived - you...

Agree, the purpose of evacuation is the removal of moisture, the vacuum rise over time is the best indicator of residual moisture in a system not the level of Micron acheived. Too big a pump on too...

You are not likely to have this modification suppported by the manufacturer as the CVGF was never offered with AFD but you do need to be aware the chiller starter and motor protection control is via...

Sorry, lost my access when I had to walk away from the mess down here after 20+ years to keep my name, integrity and self respect intact. Was also off track with the suggestion of pump pre-run as the...

Is it possible for you to pre-run the chilled water pump for a few minutes prior to the enable for the chiller?

I retract this statement as is no longer true

Correct, the "organic" rankine cycle involves heat transfer to a secondary fluid (refrigerant) with a lower boiling point than the the water/steam phase to drive the turbine allowing for the recovery...

Phase out not unil 2020 in new equipment and 2030 for the service tail.

NC, I beleive you mean HFC245fa. This is one of the candidates for the replacement if HCFC123 but has physical properties where head pressure is > than 15psig/103 kPa so a coded vessel would be...

Rob, if you read through back through this thread it might give you some answers, I suspect the developmental HFO refrigerant DR2 is intended for the S-series

Love jobs that just simply fix themselves - easy money.

I think you have it nailed as to the cause of the fault - sounds like a program setting or wiring error.

CT and PT wiring must corrolate with the wiring diagram, so on the assumption the phase loss diagnostic is originating from the Adaptiview and not the drive (based on the fact that you mention MPL...

No problems, I'll have to have an extra one for you. Cheers

No listing on the AHRI certification website as yet so suspect release for sale (including literature) is still pending
