14:30 UTC Recovered CR screens
15:15 UTC CDS had recovered the models and let me know I was good to work on SEI/SUS
15:20 UTC Start to look at SUS with Oli alog91065
16:00 UTC TJ to reset VFD panels (CS the Ends), this didn't first the first round and he went out to do it again (open up the VFD box and reset internally instead of the exterior red/green buttons)
17:00 UTC Patrick and I recovered the HEPI pressures for the Ends
17:40 UTC Reset CS HEPI pressure after Fil restarted the 4 VFDs (again)
17:41 UTC PSL recovered expect for ISS (needs to thermalize) alog91066
18:00 UTC While recovering the ISIs we noticed a thermal error on EY ISI coil driver, TJ went out and reset it which fixed it
- Jim was also called and he took over finishing up the SEI recovery of the CS
- This coil driver's thermal error returned after a bit, ST1 V1 is in thermal shutdown, Dave and I watched it flip fromV! ST1 to ST2 on the medm. alog91071
18:25 UTC Jennie opened the PSL light pipe
19:00 UTC Dave to the ends to fix the long range dolphin
20:15 UTC High Voltage was turned on, then the picos and heaters were turned back on. Fast shutter was turned on and verified
21:00 UTC Oli verified and changed if need the optics pointing based on Top Mass osems alog91081
21:45 UTC Re-energize rotation stage
22:23 UTC small power glitch, lights flickered
23:25 UTC HWS recovered for now...
