Resolved after trying different things: 23:31 UTC Hit INIT on SQZ_MANAGER. Did not fix. 23:36 UTC Turning on H1:SQZ-ASC_WFS_SWTCH as this is an SDF difference Started getting OPO saturation announcements Turned H1:SQZ-ASC_WFS_SWTCH back off Cleared filter histories Saturations stopped 23:45 UTC Tried again with H1:SQZ-ASC_WFS_SWTCH. Same problem, reverted. Set SQZ_MANAGER request to DOWN Set SQZ_MANAGER request to INIT Set SQZ_MANAGER request to SQUEEZING SQZ_LO_LR is stuck on locking OMC Tried again with H1:SQZ-ASC_WFS_SWTCH. Same problem, reverted. Can't get SQZ_LO_LR to lock OMC. Set SQZ_LO_LR to DOWN, INIT, LOCKED_OMC. Still not locking OMC. Looking at the guardian code it seems like it is waiting for the beam diverter to open. Ran 'caput H1:SYS-MOTION_C_BDIV_C_OPEN 1', as setting this to 1 has shown up in the SQZ_MANAGER log. This seemed to fixed the issue. SQZ_MANAGER has advanced to SQUEEZING. There is now an SDF diff for H1:SQZ-ASC_WFS_GAIN. Ramped gain to 1. All green. 0:12 UTC Back to observing
Good Job, Patrick!
