[Dsg-hallbgas] 2/9 cRIO Reboots

[Denny Insley]

Brian, 

   We are going to want to add some labeling to those CO2 sensors in Epics I think.
The sensors break it down into sets so if we can label them by physical location that 
may be best, i.e. "upper" and "lower".  I will look at the manifolds and let you know
which is which. Theres no hurry on this so when ever you get the chance is fine.

Thanks
Denny

Reboots are complete, it looks like the delay worked as there wasn't any gas related alarms (that I saw on clascss-alarm).

New pressure sensors for the CO2 supply have been added to cRIO, EPICS & CSS.
Note that we had to add 14.7 to the value to convert psia to psig

Currently the LOLO is 125, but I'm  not sure if that's a good value or not. Feel free to set to a better value if need be.
