GA55VSD shuts down on F0005 fault
by Dave Staley
atlas copco GA55VSD air compressor
GA55VSD Starts runs 45 sec Shuts down on F0005 fault
We shut down unit to inspect and change dip switch setting from 50hz to 60hz on siemens drive. After that would start and shut down on fault mentioned. Set switches back same result. Many mech checks, went through drive params, still nothing. Can connect a 5hp motor to leads and it runs. 75hp on unit shuts off after 45 sec. same fault. Siemens no real help other to say air end prob. Not much air produced when running for short time. can't tell if in drive or elsewhere. Copco not much help and no local certified service. Could something have changed in drive HMI when pulled out for dip switch change? I am not sure what would have changed. Any ideas would be appreciated.

G55 element outlet temp still high after service
Provided the g55 with an oil change new oil filter and air filter
After running for two hours the unit went back to it's original outlet temp which was 116 degrees Celsius
After trying to let it cool down and upon restart the compressor went into a shutdown mode with a red flashing light saying rota on the display screen, could not find what this means anywhere
