Thanks for watching everyone! This video is a behind the scenes video of me learning as I go along. What happened here was that they lost the touch display because they lost the 24VDC power supply to it. The breaker tripped so the rectifier couldn't transform the 208VAC to 24VDC to send to the touch display controller made by unitronics. There was an intermittent short so it didn't shut down until the following day. Once reset, everything worked. Intermittent probems are very difficult to trace. It shouldnt reset if there was an issue present. The touch display was taken out of the circuit so it only works off the VFD itself and has been working for a few weeks now. The unitronics controller was the culprit here. It's hard to catch an intermittent problem and it becomes more of a process of elimination type of deal to figure out the issue. The pumps are fine but there was a control issue. I'd recommend that they have a seperate VFD for each unit and let it run off that as it's capable of doing everything. No need for the extras. Thanks for watching!
@@kimware4381 Thank you so much! I really appreciate that 🙏 I'm trying and learning as I go along with some things. I found that's the best and only way to get better. Get in there, try & learn. Thanks for watching 🙏🔧⚡️🤙
@kimware4381 I'm there fixing a bunch of other equipment but they ask if I can help out with some things I don't usually deal with and I don't deny the work since it's a good customer. I always end up getting it done in the end. Be safe out there 🔧⚡️
You can clearly see which connections and wires were made in the factory for this cabinet and which were made at that place. The factory ones are nice and labeled, inserted into these finger channels, and the only thing that had to be done in this area is just garbage... and by the way, Eaton breakers are the standard format for Europe/Asia, and MeanWell power supplies are some of the best in the world.
Yaskawa has the best tech support hands down. They’re local to me (Chicagoland). They’ve showed up to job sites if they were in the area. Drives will stay on and have power after you power off. You have to wait 5-10 minutes for the capacitors to discharge out
an classic one. but please close the vfd when powering up. They can make nice fireworks when malfunctioning. The red light is normaly the DC bus of the vfd inside. wait till off/ 5 minutes
I see some bitching that you should have just done the obvious and switch on the (trip) off breakers just because they think themselves to be that brilliant. Most likely such "brilliant" persons would probably NOT have notice the lose wire as they would have "fixed the problem" and left the room. I watch and enjoy you work ethics and willingness to learn even when you encounter the unknown, so don't pay much attention from the comments of such "brilliant intellectuals".
What I understand so far evaluating the video, you have little knowledge about it components why because these type o troubleshooting should take a minute or less because the issue was obviously in front of you 🤦
That just shows how good his troubleshooting skills. You shit on him for not knowing the system but no praise for figuring it out and fixing it. He actually made it better than it was before he got there. I know nothing about VFD's but immediately saw the breaker was tripped. Not sure how long it would have took me if ever to unwrap the tape and find those bad connections. He taught me something.

Thanks! you’re good troubleshooter.👍🏻

You are a very patient and calm man under pressure to get the job fixed RIGHT! That’s what’s needed all the time 😊😊😊
A lot of people don't realize that it's easier said than done. For him to control himself and not get stressed out is a super power.
Great job Jumper Man. Those bearings were sounding rough.
Nice job JMT! I have similar ones at my job... thanks for sharing 👍
Great work broski👍🏿
Great video. Good job and nice work. Thank you for sharing. Have a nice week
Yup. This MeanWell is simply 24vDC power supply
@@TylerDurden0331 That is correct. I realized things as I went along. Thanks for the info & thanks for watching! 🔧⚡️
That's not a contactor, it's a circuit breaker, turn it on.
The feeling when finding the issue 😌👍🏼
Do you hold your phone or use a go-pro to film your videos?
That booster pump set up pressure seems really high, 110psi?
unbelievable how bad connections can make your head spin when diagnosing. great vid!
@@HVACKR Seriously! This one definitely had my head spinning. Thanks for watching 🔧⚡️
Well done
@scottmaz4063 Thank you Scott! Much appreciated 🙏🔧⚡️🤙

Great job as usuall.!!!!!

As a German, I wonder why you don't use End Sleeves
JMT. Next time call Yaskawa tech support. They are great
Can you deal with booster pumps and chiller pumps in the US and Canada as a hvacr tech?
Does it require a specific licence?
In Australia mechanical services license with restricted electrical license allows us to work on pumps/motors
Doesnt answer your question i know
@JesseDoesHVAC thank you.
Would have been helpful for them to leave an electrical drawing or the manual for that panel, but job security I guess?

Lose wires cause fires
Watching video. There is a breaker that's tripped,why not turn on and that will give you a idea of what is happening
😻💚💜💚

Very sketchy, lucky it didn’t go up in flames. Well fixed!
