[Dsg-rich] Power disconnect for RICH compressor

[Tyler Lemon]

Hi Bob,

The air compressor technician should not need to go to Hall B since the compressor will be moved to the EEL.

Hello,

Marc and I recently talked to Facilities about getting RICH Compressor 1 disconnected from power in Hall B.

They are still looking into what will need to be done and will be in contact with Denny to arrange the work in Hall B. Facilities expects there not being any problem getting the compressor at least disconnected from power and moved to EEL before the next physics run.

I asked about whether we would need to stop running compressor 2 during the move of compressor 1. They said depending on how the power wiring is set up, they may be able to lock out the transfer switch to only power compressor 2 and secure the free ends of the power leads for compressor 1.

We also stressed the a point that because Compressor 2 is currently being used, DSG should be contacted in advance if it needs to be is turned off to ensure that the system is in a safe-to-RICH state before it is powered down.

Best regards,
Tyler
