Back into Observing at 23:00 UTC

ryan.crouch@LIGO.ORG - 17:21, Thursday 04 April 2024 (76970)SQZ

SQZ_PMC is giving notifications of "PMC PZT volts low", the node returns this notification if the SQZ-PMC_VOLTS channel is less than 5. Its decayed from 80 to where it is currently, hovering around 5 over the past day.

SQZ unlocked dropping us out of observing at 00:58UTC, I also took the moment to reload SEI_ENV which caused it to lose FAIL/lose connection? I'm going to call Dave

Dave and I reverted the most recent code changes from Jim and I restarted the node with "guardctrl restart SEI_ENV", the codes changes included some states becoming unrequestable and a few other small changes, none of which made any sense for the "Index error" that the LOG had. Verbal alarms is now constantly throwing a TypeError for SEI_ENV "NoneType is not iterable". I went back into Observing at 01:14 after the SQZer relocked itself and then the MANAGER prompted me to "Return to FDS" so I requested us back to FDS
