Today SQZ_MANAGER failed to go inject freq independent squeezing multiple times. There were a couple of issues:

1) FC ASC engages when the Q error signal went below a certain threshold but didn't actually grab lock. We haven't fixed this one so the problem can repeat. Hopefully we will fix this tomorrow.

2) SQA_MANAGER waited 2 minutes for SQZ_FC to go to the correct state. See attached screenshot of SQZ_MANAGER, line 532. Without checking to see what's actually going on if the SQZ_FC guardian didn't reach its nominal state SQZ_MANAGER will just close the beam diverter and go to SQZ_READY_IFO. SQZ_FC worked fine most of the time but it just happened to take a little more than 2 minutes to reach its nominal state. The logic needs to be fixed with a loop that checks for FC_LOCK guardian state. For now we bypass the issue by increasing the wait time to 3 minutes.
