[Dsg-dc] gas cRio

[Marc McMullen]

I will be working on the Gas Shed Chassis. All DC flows should be uninterrupted. I cannot disable the Mix pressure alarms because Hall B networking is down, please disregard alarms.

Hi Brian and Marc, 

The #1 mixing tank signal flaked out when you made the changes. It's reading about 20psi high and is really noisy. 

I would also like to change the mixing settings to operate between 80-100 psi instead of 60-80 psi. 

Regards, 
Morgan
