TITLE: 08/15 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Travis
SHIFT SUMMARY:

Frustrating shift with H1 down the entire shift.  Left in the READY state at 12:10utc/5:10amPDT & with Observatory Mode = CORRECTIVE MAINTENANCE.

• Alignment looked OK. 
• ASC (for most part) was not much of an issue as long as you babysat it at certain steps. 
• Main issue was H1 could never get past LOWNOISE_COIL_DRIVERS.
• Ran an alignment.
• Later in the shift, the Green X-arm had trouble staying locked half of the time (eventhough its alignment as been looking good before/after an INITIAL ALIGNMENT).

LOG:

• 7:15 Continuing Locking with this my first Lock#1
  • Hung out at ENGAGE DRMI ASC & OFFLOAD DRMI ASC for a while.
  • Lockloss at while waiting for signals to converge at ENGAGE SOFT LOOPS.  
    • Did not see an ERROR signal ring up & so I was not able to run the Gain Reduction Script (from alog#51282).
    • I did see CONTROL and ERROR signals get bigger on the wall Strip Tool
    • Not really sure how to 
• 7:50 Lock#2
  • Lockloss OFFLOAD_DRMI_ASC
• 8:02 LOCK#3
  • lockloss at LOWNOISE COIL DRIVERS
• 8:42 LOCK #4
  • paused at LOWNOISE ASC, and then
  • lockloss (once again) at LOWNOISE COIL DRIVERS, and this definitely happened during one of the steps (around PR3 
• 9:17 LOCK#4
  • lockloss at LOCKING ALS
• 9:19 LOCK#5
  • lockloss at LOCKING ALS
• 9:23 LOCK #6
  • lockloss while trying to go through the LOWNOISE COIL DRIVERS steps via command line (not sure I did this correctly).
• 10:02 Lock #7
  • Actually, there were multiple locklosses at LOCKING ALS. 
  • Problems for X-arm at LOCKING ARMS GREEN:  Flashes were above 1, but X-ARM would lock, but had a noticeable oscillation which would eventually break arm lock.  Unlocked and tweaked...and this seemed to calm X-arm down and then be able to move on.
  • Lockloss at ENGAGE SOFTLOOPS
• 11:33-11:58  INITIAL ALIGNMENT
  • X-arm has issues remaining locked, which makes alignment frustrating.  It looks fine with transmitted nicely over 1.0, but it would randomly drop lock after a few minutes while waiting for signals to converge.
• 12:00 Locking post Alignment:  Continue to see X-arm drop out of lock randomly even with a nice alignment, and then multiple locklosses around LOCKING_ALS/FIND_IR
• 12:09 Leaving H1 in the READY state for the Day reinforcements.
