Once activities ended for Maintenance Day, immediately went for an Initial Alignment.
One item to note for alignment, was there was a lockloss where the PSL's FSS went into an oscillating state. Toggled the FSS Autolocker. And then Turned Off the autolocker for ISS 1st Loop (per instructions in January).
Currently have made a few attempts at locking, and have not been able to lock DRMI (other than a short 2-sec one) so far (even with nice flashing). Have had 1-2 more instances of the FSS going into oscillation and this need operator attention. Going to give DRMI locking a few more attempts with PRMI locks as well. After that, may try another alignment?
Definitely not rosy after Maintenance Day and something may be amiss. Will post update later.
Additional NOTE:
CHECK MICH FRINGES appears to not workin that it looks like it's trying to lock a bright fringe (or just having trouble locking on a dark fringe). Either way, it is not clear how to adjust the BS when ISC LOCK is in the CHECK MICH FRINGES state. (think this has been the case for 2-3 months?).CORRECTION: Looks like nowadays CHECK_MICH_FRINGES is an automated step (i.e. raises PSL power, dithers BS, then runs Mich Offloaded). So, looks like there is no "manual CHECK_MICH_FRINGES" like what operators used to do a few months ago.
More Notes:
BRSx continues to be in the DAMPING state post-EX noisy work in the VEA. See attached "BRS Health" plots.
Addendum: 3:23 EX signals return to normal & it returns to READY state (& SEI_CONF node's NOMINAL box turns from orange to all green).
On current lock, have had (4) attempts at DRMI with NO locks at all. PRMI locks with no problem.
Contemplating an alignment and then if that doesn't work again, will start calling for help.
Have been noticing in ISC_LOCK log that it says "Unstalling TCS_ITMY_CO2_PWR".
Going to the TCS_ITMY_CO2_PWR node shows it in a loop between "HOLD_POWER" & "ADJUSTING_POWER". Not sure if this is normal, or not, but wanted to mention this oddity (because TCSx does not have this issue).
But this might be a normal/usual thing. Just looking for anything unusual.
