Having an issue with a governair screw type chiller. It has 2 (50) ton compressors. #1 has hot gas bypass and should stay running and #2 comes on as demand calls. I'm having trouble keeping #1 on line. Controllers are saying alarm but but no alarms recorded in allerton controller or Siemans apogy front end. No mechanical alarms that need resetting. But unless I put it in hand ( runs normally) or reset the chiller by terminating power that it shuts off and #2 runs.
