Entry number 51927

There were a couple problems during the radiator test.



1) The FSDs tripped the beam after we moved to the 2% foil.

2) The radiator was moved to the out position, but stopped at the foil 1 = empty

    position and would not move.



I checked the status on entering the hall.

1) The water cooler showed no flow rate and no pressure. I turned it off

    and on again, and it remained the same. The FSD trip was valid, but

    I do not know enough about the system to want to play with it and

    figure out anything further today. There is no evidence from the target

    vacuum or on the floors of a water leak, so I might suspect the pump

    failed, but why would this happen to coincide with our putting it to the

    2% foil.

2) The motor control supply showed no holding current, as opposed to the

    I think 1.8 Amps when I turned it on. Turning the box off and on

    again had no effect. Again, why did this happen as we pulled it out, with 

    by this point noi beam on target.



I manually moved the radiator out, by removing the bearing on the 

drive screw, banging it in the process, and  blocked it in the out position.

The water cooler and motor controller box are turned off.
