TITLE: 02/12 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: The HAM7 doors are ready to be put back on, the CS pumpdown has begun, and EndX & HAM8 are being prepped to be vented.
17:59UTC SUS ZM5 WD trip, LVEA RED pressure alarm 18:30UTC, a few PSL anteroom yellow dust alarms throughout the morning/early afternoon then several red alarms around 22-23UTC.
21:12UTC ISI HAM7 WD trip, maybe from Gerardo turning down the purge air? ISI HAM5 & 7 tripped a few minutes later 21:18UTC and the motion was too high to untrip for a bit (~ 4 minutes), probably from the VAC teams work, sudden changes in pressure? Tagging VE, SEI. They retripped 2 minutes after I reset them after the motion look like it had calmed down. I'm going to leave them tripped for now.
21:51UTC the CS pumpdown started!
