Hello all,
New poster (long-time lurker) here looking to pick your brains on my Quincy compressor.
First off, specs:
Quincy Qsync Twin Screw Compressor
50 HP
Mfg Date: 2004
Model #: QSYNC50ACA14A
480v 3ph
73,000 hours
The compressor is inside an air-conditioned plant, with metal mesh filters on all air inputs. All maintenance performed on schedule.
Drive:
Siemens SIMOVERT VC Drive
Model Number: 6SE7027-2ED61-Z
With that out of the way, I am having issues with random shutdowns and the error "Phase L2 Problem."
This has been going on for at least 2 years, but recently the shutdowns have become more frequent with it shutting down twice or more in one day. We have talked to Quincy, they won't touch it (The software is gone and no way to download it from the drive). They did look at the voltage for over two weeks and no abnormalities were present. The tech said that these compressors are usually kaput around 50,000 hours.
I talked to Siemens, they no longer support the drive or do any work on it. The manuals just state that there is a certain board that "may" be the problem, along with two others.
Does anybody have any advice on what I can do to fix this issue? This is the main compressor for our whole plant, my backup can barely handle the plant air requirements, so I really need this fixed.
