[Dsg-rich] URGENT: RICH alarm

[Tyler Lemon]

Hi Bob, 

Thank you for your reply. We can see that flow has started again. 

Is this valve going to be permanent? Or will there be a time in the future where flow will be stopped again to remove the valve? 

Best regards, 
Tyler

Hi Tyler, 
The N2 was stopped to add a valve; it will be back within the next 10 minutes.

Hello Bob and Denny, 

Is there any work being done on the forward carriage nitrogen supply line? 

RICH lost N2 flow and the aerogel needs to stay constantly purged by N2 to stay dry.

Hi all, 
it seems that few minutes ago the N2 flow dropped to 0. 
Can someone please check what is going on? 
Thank you 
Marco
