Remember To Also LOAD Script
For the ISC_LOCK guardian, Jenne hit LOAD button this afternoon to allow Guardian to take H1 to 23W.
Last night for Sheila/Cheryl H1 troubleshooting work, the script was set to 10W, and Cheryl changed it back to 23W & saved it. But H1 was in Observing, so she was not able to hit the LOAD button (is that allowable in Observing?). Anyway, this afternoon Evan noticed H1's power was only taken to 10W. After H1 dropped lock, Jenne hit the LOAD button.
If H1 is in a safe state, one should remember to also hit the LOAD button after making changes to scripts....or flag-the-alog/let-next-operator-know to LOAD during next opportunity.
PRMI Transition Didn't Work
During locking this afternoon, DRMI took more than 15min, so I selected PRMI. PRMI locked and alignment was optimized. Requested DRMI LOCK, and H1 switched immediately from PRMI to DRMI, but unfortunately, the Guardian was stuck here. Perhaps next time we can try re-requesting DRMI LOCK?
