Yutaka,
Sorry about not mentioning the hair decoration; Alex really liked it.  She will take a picture when she wears it.

Sounds like Y3 still has an air problem.  Did it settle down after running?  Maybe the HPS mods don't work that well.

The 469D interlock is supposed to clear out all of the selected buttons so that they will NOT try to restart after interlock shuts them off.  I did test that really hard; I am unsure why it did that.  Could be that some signal from the PLC did not correspond to what I think 469D should see.  Keep an eye on that problem to see if it happens again.

We don't need to change the ramp time unless the ball valve motor has a problem.  The main reason to ramp the pressure to zero is to allow the ball valve motor to START opening the valve.  When the valve is closed w/ 3000 psi on it, the ball valve seals then require A LOT of force to crack the valve open.  Once the valve is open, I do not think that it takes very much force to continue to open the valve even w/ 1000 psi low pressure on it.  So, unless there is a problem w/ the ball valve motor (definite signs of straining - speed lowers, motor stinks) then I do not think we should have to change the pump ramp time.
