Here's what I get when I try to load the sample. 'There were errors on the last procedure. Please verify first.' [Hit OK] 'Error 212 - MoverRobotArmIn' 'Error 213 - MoveRobotArmOut' 'Error 212 - MoverRobotArmIn' [Hit Reset] 'Cannot Reset Access Denied' To prevent frustration among users, I'd strongly suggest emailing to the list in addition to putting a comment on coral in the case of a problem. I'm canceling my session.

The system was reset twice -- once in yellow button standby mode and second by using the red button reset manually. I then brought up the vacuum pumping of the RAITH chamber Turbo and then the Ion pumps followed by a service run up of the FE-GUN. I expect this system will come down hard in the next few hours to days if the water flow does not improve. Current temp of E/O card at system is 38 degrees C. Flow is below 0.1 lpm. System is currently up and available to users. Please call me if the system vents or the gun shuts down.

High pressure blow out to remove everything that would come out. Now running up gun and gun vacuum levels are higher than expected during service run up.

Message-ID: System chamber pump down went faster than expected. Gun section Ion pumps fired as set point crossed at about 15:00 hours. Waiting for lower FE-Gun pressures before enabling EHT to protect the gun section from burst in pressure which could contaminate Fe-Gun tip. Currently system vacuum = 5.5E-006 T. Gun vacuum = 1.9E-009 T and falling steadily. Best efforts to return system to users this evening. A replacement turbo is on the plane for Monday delivery.
