1515 hrs. local -> Opened LLCV bypass valve one turn ccw -> less than 1 minute until liquid was evident out of the exhaust -> This is much different than has been recorded by Gerardo in the past few days (3 - 4 minutes) and is likely due to differences in our interpretations. Also, I routinely open the instrument air bowl drain valve at the pressure regulator near the LLCV actuator to verify that dry air is being supplied to the actuator -> Today this looks to have resulted in a disabling of the Start - Stop for this on the MEDM screen, i.e., the indicator bar went from green (START/enabled) to red (STOP/disabled). I had to re-enable this.
