[Dsg-rich] [New Logentry] RICH high temperature interlock came off again.

[Amrit Yegneswaran]

valery, 
as marc's email yesterday suggested, keeping the roll up door open increases the temp in the hall. 
tyler looked into the matter today and noticed that the hall temp goes up by 5 F. 
(tyler will send a detailed report after the dsg meeting tomorrow) 
so for now the options are: 


    1. ask that the roll up door be kept shut, as much as possible . 
    2. increase air flow by about 5% 
    3. increase threshold by another 3 C. 

in reality we have 3C3+3C2+3C1 +3C0 options!

We have the same situation today around noon: high temp interlock (N5 and 6) switched RICH off lv and hv. 
I increased (+2C) the high limits at these sensors. It is still acceptable for the front-end electronics.
