Question
I have a problem with my atlas copco ZT90 stop due to main motor converter alarm. there is no fault code in the display alarm. just main motor converter alarm. It says timeout.
I need help please
1 Answer
timeout usually means a communication error between the compressor controller and the VSD drive.
Check for an error code on the converter/VSD drive. Then post here or search google for the code...
