Question
We are installed with Atlas Copco compressor Model GA37 , Compressor starts up normally and trips on ROTA error , Replaced thermostatic valve but problem still persists , Request Technical advice on cause of fault .

I'm not sure what 'ROTA' error is - but it might mean 'rotation error' - which probably indicates that the compressor is running in the wrong direction.
A screw compressor can only run in 1 direction. It is indicated by arrows on the motor and/or screw element. If it runs in the wrong direction, the screw element will be damaged very quickly!
If it is running in the wrong direction, you need to swap two phases of the power supply to make it run the other way.
Please check it first and let me know if you still have problems!
All the best,
Cas
