QUICK SUMMARY:

Another Lockloss
This Lockloss has some really interesting motion on the ETMS and ITMS  for atleast about 2 minutes before the lockloss.
My heade was burried in my laptop at the time, but I don't know what I would have done had I looked up and seen DARM acting that strange.
And once again SUS-ETMY PI ESD Driver had sustained elevated activity up above 2000 - 3000. there were no verbal alarms about elevated PI's 

I readjusted the H1:SQZ-SHG_FIBR_REJECTED_DC_POWER back down again.
Sitemap -> SQZ overview -> SQZT0 -> click half wave plate. seen here:
then opened the controller screen via the button.
then clicked on the correct Pico motor,  then enabled it.
This allowed me to move the pico motors in the Up down and left right directions which move 2 differerent wave plates while watching the NDSCOPE to minimize the signal.
be sure to move the pico motor slowly, and dont request a move while it's yellow. I was told to click it & let it finish.
