When locking after the PSL RefCav alignment touch-up, Needed to tweak both green arms, but the oddity this time is ALSy's WFS would not stay engaged. 

From ALS_Overview screen, opened the PLL & PDH screens and they both had issues.  Able to track down issue (by watching the flashing RED status which said "Laser Error".  So opened the ALS Laser medm (attached), and here Sheila noticed a message flash which said something related to "Diode 2".  The Laser Diode 2 Monitor is hovering around 1.6.  This value was out of range for our settings.  [Nominal was 1.4 with a tolerance of 0.2....so we were currently right around the limit of 1.6]. 

So nominal channel (H1:ALS-Y_LASER_HEAD_LASERDIODEPOWERNOMINAL) was changed from: 1.4 to 1.5 to allow for the ALSy Diode 2 Power drift up.
