IFO Prep for O2A closeout
At the agreed time for the end of O2A, Fil and Peter helped by breaking the lock with an EY incursion (I forgot/didn't realize how close they were getting to the chamber...).
With the IFO now in down, I:
- 1. Put ISC_LOCK in down
- 2. Put the SEI_CONF node in SC_OFF_NOBRSXY (which I verified turns off all ground to ISI/HEPI feedforward) and
- 3. Moved all of the ISI's to damped with TJ's TRANSITION_ALL_SEI medm.
- 4. JeffK has confirmed that all sus except for MC2 are align (MC2 got misaligned when the input HAMs were moved to damped, to keep the IMC unlocked)
- 5. I also disabled the damping on BRSX (in case there are any rogue EX Beckhoff restarts)..
The LVEA is being transitioned to laser safe right now.
Such that MC2 is also aligned, I have un-managed the SUS_MC2 guardian, and set it to Aligned. In order to re-lock the IMC, we will need to run Init on the IMC_LOCK guardian to reacquire management of the MC2 guardian.
