| The solenoid quenched this afternoon at ~12:30. The compressor shut down. Fault lights were cold box trip.
Restarted the compressor by 3:30 and started flow to the solenoid by 4:15.
Peter Yandon came down with Ops' radio to investigate the radios may trip the solenoid. When the radio is keyed the vacuum guages jump. CG1, CG5 and the pirani gauges. This would trip of the refrigerator. More investigation to happen tomorrow and on maintenance day. |
