While relocking, the OMC_LOCK Guardian reported a "Wrong mode?" notification just before DC_READOUT. The OMC Trans camera looked great, so I wasn't sure of the issue. I looked through the code and H1:OMC-DCPD_SUM_OUTPUT needs to be > 14 for it to move on. This channel was around 13.0 +/-0.5. Jenne thought that the PSL power was slightly low, and suggested that I use the rotation stage to bump it up a few tenths of a W. Evan also gave his nod of agreement and I changed the rotation stage from a request of 2.000W to 2.100W. Nothing. Then from 2.100W to 2.400W. Success!
While I was adjusting this, Jenne was inputing the PSL power into a small box on the LSC_OVERVIEW (shot attached). The Guardian will normally write to this value, but since we were changing it, it needed to be updated. So for future attempts at this, make sure to be changing the value in that box as the PSL power changes to keep everything happy.
