Manually over-filled CP3 
1440 -1510 hrs. local -> To and from Y-mid 

Opened exhaust check valve bypass valve, opened LLCV bypass valve 1/2 turn -> LN2 @ exhaust in 60 seconds -> Restored valves to as found configuration. 

Next CP3 overfill to be Friday, July 15th. 


Also, demonstrated MTP Safety Valve functionality when backed by local scroll pump (rediscovered that the "NORMOAL" light LED on the turbo controller is burned out) -> Let MTP brake phase complete but am leaving turbo rotor levitated, i.e. controller energized, overnight -> will de-energize tomorrow.

~0900 hrs. local -> De-energized Y-mid Turbo controller (Foreline 1.2 x 10-1 torr, turbo inlet 2.6 x 10-1 torr seams odd - gauges reversed?)
