Vacuum at 1.7E-7 T

Corrected title from off to timed out . It seems the controller lost contact with the pump when I touched the rack. The pump recovered right back to 38 kRPM upon restart.

The valve closes physically, but does not receive the closed signal.

Cycled the valve multiple times before finally showing closed state.

TSG:RP1 backing line pressure is >200 mT. An e-fault has been submitted to have the roughing pump replaced.

Friday, April 24, 2015, 13:13: Pump replaced by vacuum group.

 Power supply did not work after high voltage conditioning. On Friday May 1st John Chow replaced the power supply with a 12 V 100 A power supply temporary while the other supply is being repaired. EPICS controls have not been adjusted.

Everything shut down, while EPICS showed everyhing to be on.

Controls group (Dave Morris) has reestablished contact. System is operations.
