Symptom
MAC00001 PDS Alarm Magnet Efficiency Issue detected a Magnet Performance Issue, Magnet Pressure increasing and Heater Duty Cycle at 0%. The OnWatch engine has determined that the magnet efficiency is degrading,pressure is trending up and the Heater Duty Cycle (HDC) has been at 0% for an extended period of time. See long description. NOTE: The Digital Services (DS) Rules Engine detected this problem. This issue is only applicable when detected in this way, and should not be reused in Knowledge objects for normal reactive magnet service. This is an automated alarm generated by the OnWatch program. An algorithm was run on the data uploaded from the MM3 into Insite2. The data shows an upward trend in the magnet pressure, which has now reached a trip point of over 4.25psi. The Heater Duty Cycle (HDC) has been at 0% for over 5 days. The OnWatch engine algorithm is used to filter out site power issues and water chiller issues, compressor should have continuous run time.. A sharp increase (spike) in the data is filtered out. This alarm should point to an issue with the efficiency of the cryo-cooler circuit.
