Good day Engineers,

Could someone please help.

What could be the reasons for a Trane CVHG, adaptiview tracer CH530 to display ALARM: Compressor did not accelerate shutdown?

Thank you

Probably current have not been detected by current transformers. Or controller did not get feedback from aux contacts of main contactor.

Thank you Mr Alex for your suggestion, it is my first time of working on CVHG unit and I did not perform any thorough check on the unit..
The next time I go to that site, I will check just as you have suggested.
Thanks
