SHIFT SUMMARY:
Lockloss from NLN , Lockloss tool failed again.
Thefirst channel that I was able to see deviate from its nominal operation was ETMX L3 channels.
screen shot attatched.
Relocking notes:
Relocked after another IA that unlocked and faulted the IMC after Saturating MC2. Doing a manual IA does not cause this issue.
Once passed DRMI, it locked without issue until NLN where the 1 hz ring up happened on the ASC-INP1-P. Elenna had me use the ASC high gain button for about a minute.
Once that had properly damped the oscillation and used the ASC Low gain button we were able to do some Observing.
Observing reached at 00:15:01 UTC
