TITLE: 10/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Oli
SHIFT SUMMARY: 3 lock losses during my shift today, the first two looked vaguely similar, but we haven't come to any conclusion as to what the cause was. The last one was due to a ADC card failure at SEI EY. During troubleshooting of this the interlocked was tripped and we had to recover all of the site lasers after the ADC card was fixed. We ran an initial alignment and we are now back to NLN. For both of the relocks in the morning the 1Hz ringup didn't show up, but we just saw it come up for this lock. Oli pressed the new high ASC button.
