[dsg-hallb_svt] CVT work

[Yuri Gotra]

Thank you Brian,


I asked Sergey to install the switch. We will take care of moving the 
V450 crate tomorrow. If you have recommendations on location of other 
crates, please let me know, we have the manual forklift in the clean 
room. I expect releasing the Dynalene by RadCon soon and will proceed 
with testing the cooling system. Do you mean the thresholds in the GUI 
or EPICS settings? Could you please send instructions on accessing the 
hardware interlock GUI from EEL124. To start, we need to wire the 
signals coming from the cooling system (temperature, pressure, flow), 
and purging (humidity).
