I bypassed the chiller at the bubbler until I get a chiller working for CMU.

I took the chiller out of bypass. The read back is not working properly. I have a digital thermometer on the CMU bubbler that reads 23ºF and -5ºC. The readout on the iFIX page is 31.5ºF.

Scico called and wanted the West End Plug 400Hz cycled. Upon doing it, it caused a GEN ALARM which I reset and reset the 400Hz. They came back OK, But, the whole West side arch P.S.'s went south(half of them have a comm error and the other half are in ALARM.) SCico is consulting a expert.

Warren just spotted a LN2 leak at the supply line for the COT cold traps.
<!-- Author: Jim L -->
<!-- Comment: Tue Nov 20 14;03;52 comment by...WB -->
I disabled the cold trap regeneration, let the union warm up and tightened it, along with all other accessible unions.  Regeneration is reenabled.


<!-- Comment: Tue Nov 20 14;19;38 comment by...Del -->
Warren meant LN2 fill is enabled rather than regeneration.

Bob Wagner requested that the Ar-O2 flow be increased from 0.125 scfh to 0.175 scfh. I did this and reset the alarm limits for the flow and O2 level on the COT alarms page. The Ar-O2 bottle is currently at 308 psig.
