ID Date Author Operational Mode Subject Text   252   Fri Jul 25 21:48:15 2008 Doug Preddy Quench Recovery another quench System was stable and solenoid ramped up at 4:00 today. At about 7:30 it tripped off again. I came in and restarted the compressor      253   Sat Jul 26 01:06:04 2008 Doug Preddy Quench Recovery Refrigerator in series mode Switched to series mode. Solenoid ~8K, starting to build liquid.       254   Sat Jul 26 01:29:21 2008 Doug Preddy Quench Recovery power leads ops will monitor liquid level. When it's at 60% they will come down and open the power lead valve. When the temperature ripples      255   Sat Aug 23 17:02:38 2008 Doug Preddy Quench Recovery Solenoid quenched The solenoid quenched this afternoon at ~12:30. The compressor shut down. Fault lights were cold box trip. Restarted the compressor      256   Sun Aug 24 06:45:14 2008 Doug Preddy Quench Recovery switch to series mode        260   Fri Sep 26 09:45:18 2008 Doug Preddy Quench Recovery Solenoid quenched at 7:50 Compressor on. Turbines started. Vacuum system recovering.      261   Fri Sep 26 09:50:18 2008 Doug Preddy Quench Recovery started flow in parallel cold return mode        263   Sun Oct 5 18:54:27 2008 Doug Preddy Quench Recovery Solenoid Quench ~16:30 Restarted compressor and flow to coldbox by 18:30      267   Wed May 27 08:06:00 2009 Doug Preddy Quench Recovery Solenoid quenched at 5:00 The solenoid quenched at 5:00 this morning due to power lead temps. The temps started oscillating about 10 minutes before the trip.      268   Wed May 27 13:37:22 2009 Doug Preddy Quench Recovery switch to series mode Switched to series mode at ~11:00. Built liquid to 55% by 13:30. Started flow to the power leads.      269   Wed May 27 15:01:34 2009 Doug Preddy Quench Recovery power leads Power leads are cold. There is still a small ripple. The power supply can be ramped up as soon as the ripples die out.      270   Fri Jul 10 00:34:03 2009 Doug Preddy Quench Recovery solewnoid quench due to power bump Solenoid quench due to power bump caused by an airplane crash in Richmond at ~ 22:00. Compressor off. Water pump off. Restarted      271   Fri Jul 10 01:10:59 2009 Doug Preddy Quench Recovery switch to parallel warm return        272   Tue Jul 14 15:28:36 2009 Doug Preddy Quench Recovery Solenoid ramped up The solenoid is cold and I have started to ramp up the power supply. Some slight ripples in the power leads, but they are      277   Fri Apr 9 07:34:55 2010 Doug Preddy Quench Recovery switched to parallel cold return Switched to parallel cold return at about 7:30 this morning        279   Mon May 3 07:49:54 2010 Doug Preddy Quench Recovery Solenoid quench Saturday Solenoid quenched at ~13:30 Saturday. Kevin came in later in the day to recover it. System was in all around mode, no flow to solenoid.      280   Thu May 13 07:39:55 2010 Doug Preddy Quench Recovery solenoid quench last night Solenoid quenched on power lead temps last evening. I am recovering it in parallel cold return mode. C12~60K C1~50K.      281   Thu May 13 14:37:13 2010 Doug Preddy Quench Recovery switching to series mode.        283   Mon Jun 7 09:24:47 2010 Doug Preddy Quench Recovery started flow to power leads        99   Thu Jun 9 06:53:40 2005 Experimentor Other Trip at 6:45 Today. Solenoid quenched at 6:45.  All temperature monitors were flat until trip.   Hearing compressor stop was first warning.
