TITLE: 05/21 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 17mph Gusts, 13mph 5min avg
Primary useism: 0.08 μm/s
Secondary useism: 0.11 μm/s
QUICK SUMMARY:
Took H1 Out of Observing to do a SQZr Scan.
Incoming 5.4M Earthquake. - Survived it.
Locklosss from Observing 02:31 UTC
Screenshots attached.
H1 made it all the way up to LOW_NOISE_LENGTH_CONTROL and was knocked out of lock by what I pessumed was wind. But looking at the scopes I dont see any extreme gusts.
On the Second locking attempt H1 also made it to LOW_NOISE_LENGTH_CONTROL, But both times i made it to that state it lasted 2 seconds and 124ms, then lost lock. which looks suspicious.
I started to try to open ISC_LOCK to stop it from getting to that state, and was greated with the following.

Tony, Dave:
We noticed that two scripts in isc/h1/guardian had been changed this afternoon around 16:22 relating to the errors being seen. I made a backup copy of ISC_library.py and ISC_LOCK.py and removed the recent changes using the subverion revert command. The immediate problem of ISC_LOCK's non-functioning ALL button was resolved.

Ok Looking more into these locklosses in LOW_NOISE_LENGTH_CONTROL logs. They both stop exicuting lines at the same time.
Using Meld I was able to find the difference between the 2 versions of ISC_lock.py within the Low_Noise_Length_control Guardian state.
It looks like line 5559 was commented out.
#ezca['LSC-PRCL1_OFFSET'] = -62 # alog 76814
Update:
Jenne wants that to stay put. Cause it needs to stay at 0.
I will walk it through line by line using the guardian command.
