Liebert GCB ambient temp diff
Просмотров 2319 часов назад
The reasons why your getting gcb ambiant temp diff. When you have dual condensers if the ambient sensor is reading more the 10 degrees difference between the other unit you get this alarm and most likely you have a bad sensor in one of the units or a bad mc condenser fan board. Buy both sensors and a board save yourself a trip.

Liebert challenger 3000 low pressure

Pressures looked good when gauges connected. However kept throwing low pressure alarm and locking compressor out. Hot gas solenoid partially stuck open making suction pressure appear good. Pulled dryer and was plugged 85%. Customer said tech was telling them they had a bad board.

Boy, i tell you. Being a mechanic in this age is both a blessing and a curse. Id imagine it would only take another 15 years before any "quality" mechanic also holds a degree in software language.
@@blu-birb it’s become more electronics then anything I’m a refrigeration mechanic who was hired for y2k project and been with Liebert ever since
Having this problem currently on one of my units. Just changed the super cap board but still have the battery bad error. Is there any setting I need to reset after replacing it?
@@pipedown7969 you need to let it charge then reset the counter
@@pipedown7969 I’ll try and make some more videos on this next week
@@hvac-runauthorized7326 cool thanks for responding man I will give this a shot. I’m trying to get my company to send me to the Vertiv training in Ohio because these things are so intricate. Even with an HVAC background they have so many settings it can get hard to troubleshoot some stuff.
Thanks for the content on these things, it’s pretty difficult to find any troubleshooting help on them. Was wondering if you ever experienced a “bad battery” error with the EEV board? I have one currently where the suction line thermistor is showing around 8degrees when i measure it’s actually 47 and the circuit won’t calculate any superheat. I replaced the thermistor which didn’t solve the issue, then the EEV board and the super cap board. Turned the unit on and still have the issue with the thermistor showing 8degrees and the EEV page is showing ”battery bad”. Do you know if there is some sort of setting I need to reset to clear this after replacing the boards?
@@pipedown7969 set the eev to manual at 38% and see what the pressure looks like
@ I’ve got a tandem compressor circuit, should I just run it with one on and see what I get? It’s just weird that it’s showing a reading of 8degrees but when I take a measurement directly at the thermistor with a thermometer it’s showing 47
@ run both
If you run at that eev position you will see the real pressure. A lot of times the unit is undercharged or the gas is contaminated
If you have core dryers check your td
One of our sales men just sold a contract to a data center in SC so we’re about to pick up a ton of Liebert units. He sent me the equipment list and there’s some Trane, Carrier, and Rheem but the vast majority are Liebert. Lots of DS, DCD, DCS, VS, and a couple MCL. Just trying to see what he’s getting us into…

Nice! I had a leak on pressure switch cap tub last week. Lost about 40lbs of r22🙁
This trick is only good on the ds/vs
I’ve had a few of those leak and the tubes crack off
@treasuredtimescruising8265 Right, the one I was working on was an older VH model. Unfortunately, I had to replace it with another manual reset high pressure switch that had a cap tube.
👍👍
Stand off ( board supports ). Pimp shit. Thanks.
What about the control box for Ethernet?
This model requires a isUnity DP kit to connect to Ethernet
No offense but that manual was the worst one i ever read. They are so vague about everything. None of the wires are labeled or have numbers so on the vertiv split they for instance have two brown wires and you have to pick the right one. took forever to figure that out before it dawned on me. nice units bit they need to make things just a bit more installer and service friendly. Even just a simple label on the service panel would have been nice.
At the condenser yes I know if you look close there are numbers by the end for 1 and 4. The blue and white are not numbered either you have to look at the condenser wiring schematic to figure what number they are
Hi Sir, I have a question about MC board after the installing of the board if we need to configure the board
If you are just replacing the board you will need to make sure it is set up properly for your system. Psi or bar Freon type etc plus it’s a good idea to run it through the motor set up process
I am doing 2 condensors connected a econophase and a crac unit.do you have any videos of wiring,charging and piping on those?
Not at the moment. But be careful with the piping if it’s not correct they start up guy will make you change it. The next one I come too I’ll make a quick video
Also keep in mind this is an anauthozed Chanel I do this to help people that may question some of this stuff. I work on these systems everyday.
Thank you.i followed the piping by the book.ive done a couple of 5 ton leiberts but this is the biggest one I've done.
They get very big. Use nitro when brazing and pull a deep vacc 250 micron or better and it will run forever
