PSL back up and running
Peter K answered the call and walked me through getting it up and running again. The chillers were running with no errors, but I did have to go out to the LVEA and turn on the NPRO power supply at the PSL1 rack. Peter mentioned that the Ref Cav Trans is low, and I noticed that the Relf image looks a bit different than what I have seen recently.
Tripped off again at 10:47 UTC. Called Peter again and this time the chiller had tripped off and sprayed water everywhere like it normally does. I topped off the Xtal chiller with 300mL, and the diode chiller was reporting low temp.
We are back up now, with similar conditions as before.
