Had a bit of trouble for ALS_XARM flashing PDH faults, but went to DOWN/INIT & it came up fine the next time.
SDF Diff was due to the EX H1:ALS-C_LOCK_REQUESTX requesting RED Locked instead of End Locked. Went to End Locked and this took care of the Diffs (for H1SYSECATC1PLC2 & H1SYSECATX1PLC2).
4.735kHz Mode: Was rung up as in last lock. I changed the MODE10 from FM4, FM9 (+30deg) & FM10 enabled---> and went to only FM4, FM10 being enabled. This quickly took down the 4.735 kHz Mode under 1e-18. ACCEPTED this in SDF.
PI Mode 28 & 27 rung up---flipped their phase signs and they were good.
2:32 OBSERVING
PI MODE 27 came back up again. Flipped the sign to address it.
