I’ve never been an HVAC guy, but I was a master electrician for over 10 years. I now run a IT support company. When I watch your video (great video BTW) I always wonder why these machines don’t have a least a web based interface you can login to a remotely diagnose. Even better would be remote monitoring of different parts of the system so you could activity monitor all your clients systems without even stepping foot on-site! The units all seem to have logic boards onboard so it would take much more to at least have we’d interface. We manage about 2000 different machines, servers and workstations, plus printers, switches, routers, etc. we are constantly getting telemetry from each machine. If a machine is reporting errors the system will actually open a ticket, run certain remediation programs, and actually try to fix the machine. If it is unable, it will assign the ticket to one of our txt to resolve the issues. It just seems like you guys should have similar technologies available to your industry. Instead of having to do a truck roll every time my system is acting up or better yet head off a major problem because before it becomes a big issue.

Cant really dog the technology or Trane. That's one of the most efficient RTU units on the market. I agree it looks like the main reason the VFD failed is because the door was off, froze the evap coil, created a lot moisture, and they clearly have not been blowing out the VFD with nitrogen. Any cond motor will fail if the cond coil gets really dirty which raises the operating temp of the motors. I work on Trane equip ALOT and I was really impressed at how you figured out how to make the blower run by a contactor. Great job! I wouldn't be surprised if a pigeon pissed in the VFD also.

Yorks often have the blower VFD right in the mixed air location close to the blower. I'm assuming they likely coat the circuitry to be compatible with a more humid environment... Also, the more bells and whistles with communicating equipment and VFD controls to help make the equipment run more efficiently will cost the customer less with energy but will always cost the customer more in the long run as these fancy parts are insanely expensive to replace when they break, and the expensive fancy parts are the ones that will break.

When the touch screens get really dirty around where the bezel meets the screen they don't respond to touch very well and won't calibrate. Take a wet wipe and clean the screen and around where the screen meets the bezel with the wet wipe and your fingernail. Get all that crud out of there and off the screen and that should do the trick. Automotive plants have thousands of touch screen HMI's and robot touch screen teach pendants. They are always dirty and not working well. A little cleaning works wonders. I think the 38 (1284) code is a communication fault (error) between the control card and the power card (don't have my manual for it anymore). Re-seating the cards in the drive and connectors going to the cards has been known to work.

I think I might start using it again. Is there a "Core Charge" on VFDs? As in, are failed ones sent back to the manufacturer for refurbishment/repair, allowing you to purchase remanufactured drives in the future, or do they simply become e-waste? As others have noted, the dirt on the touchscreen was likely causing the calibration failures. Those appear to be resistive touchscreens as you'd find on thermostats, as opposed to the capacitive touchscreens more prevalent in our technological goodies like phones and tablets. Dust buildup, especially around the screen's bezel, can cause pressure on the screen, leading to false inputs. Resistive touchscreens rely more on pressure, hence why you can operate them with gloves on, or pointy objects like a stylus, pen, key, etc.

@@BenTh17 i run into that high pressure switch trip often. Aaon tech support has no clue what the problem is and tell you to call Yaskawa (for the CFM on drives). Yaskawa rep will tell you they get calls about it often, they’ll walk you thru the parameters AAON ENGINEERS WANT, maybe have you change a few things. It will still trip pressure switch. I haven’t ran into over charge yet. I have a building with about 40 Aaon, and all the 16 ton units have this issue, with a mix of straight DX cooling and DX+reheat. I legit believe it’s the way Aaon’s controllers/boards are computing what the pressure transducers are reading. Still working on the true solution on this one, whenever I go to site. Maybe the fan blades are pitched wrong… maybe it’s the micro channel coil design….. Aaon is literally no help. Couple of my favorite Aaon moments: Brand new unit (don’t remember tonnage), 2 circuits, each with 1 comp and 1 CFM. Both circuit would trip high pressure. Ended up finding CFM1 wires landed on CFM2 relay and CFM2 wires on CFM1 relay. Call stage 1, Comp1 runs, CFM2 runs. Another Brand new unit… was having control voltage issues. 24v would be here, but not there, then it would go away completely. Every single wire landed on the low vault terminal blocks, both the 24v and common blocks, they didn’t strip the freakin wires before crimping on the push connectors…. Like what the eff?!!! I’ve been told they test every unit before it leaves the plant… I kinda miss using my Aaon/Orion handheld controller….back when Aaon was actually one of the better brands.

Buena tarde Chris, un video de mucho trabajo y mucho que pensar, y la verdad no entiendo por qué venden estos equipos muy caros y además los repuestos con precios muy elevados. Entonces dónde queda el ahorro de energía. Gracias por todo lo que enseñas Chris, saludos desde Coacalco Edo de México.

Ridiculously expensive parts - very true statement

"Rebadged" Danfoss drives. FC-202P3K7T2E20H2XGXXXXSXXXXAXBXCXXXXDX is the equivalent but I would recommend a IP55 enclosure (change the E20 part in the model number to E55), problem with that is that the size gets bigger (from A3 to A5). Another option is coated pcb FC-202P3K7T2E20H2XGCXXXSXXXXAXBXCXXXXDX, same size but the pcb's are coated against moisture ;)

Have you had any issues with the ranco etc controllers as far as the sensors not being accurate??

The thing about drives is honestly they need a weather rated passively cooled drive
@robmcshane32608 ай бұрын
Chris does the drive come preprogrammed from factory or do you have to set it up in the field??
@HVACRVIDEOS8 ай бұрын
I was told it came programmed but I was also told to use the old display just in case it didnt
