TITLE: 12/02 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:
Main activity of the day was the the SUS DAC swap at EX (with the addition of more CDS work at both end stations as well).
In parallel, there was also crane inspection work which initiated gate valve closures due to loads needing to be craned over the beam tubes in the LVEA. Then in the afternoon, it was decided to open the gate valves for locking (so we could see how the End Stations looked after their big changes today).
[Through today's recovery to relocking, there were several items which needed to be done. Had much help from many who made recovery fairly easy **knock on wood**.]
Towards the end of the shift, able to see light flashing in the arms, and started an Initial Alignment (one gotcha was during Scan Alignment of Green Arm alignment which made the ALSx + y guardian nodes red---Ryan and Oli were on top of it and able to get alignment back. Other than that, alignment completed with no other issues. Moved on to locking and locked DRMI pretty fast on the first attempt....unfortunately there was a lockloss at DHARD_WFS.
NOTES:
- Not totally sure of where we want to leave H1 for the night. There may be other people on-site to babysit for a bit (currently, I'm leaving H1 as it is trying to lock (had DRMI lockloss for a 2nd time post today's big day). Ryan & Oli happen to be here to babysit, but if H1 isn't locked after the last operator leaves, ISC_LOCK should be taken to DOWN!
- DIAG MAIN has the following note: "HWS: HWS code stopped for ITMy"
- VIOLIN_DAMPING is also in PAUSE (as was the case yesterday)
- PCal also having issues, but Tony is looking at that with Dave
