I found the BSC 9 ISI tripped this morning, Stage 1 Watchdog trip, actuator limit was the first trigger.
I also noticed that yesterday morning the ETM reaction mass was misalinged, and -600 coutns offset was added in ETMX M0 Locking filters. I've turned both of these off, but still don't see a reflected beam, so I'm heading to the end station to have a look.
We are back from the end station, the TMS offsets were also off. Also, the ITMX HEPI and ISI were tripped, with a CPS saturation alarm.
