[Dsg-rich] RICH N2 cRIO modifications

[Tyler Lemon]

Hi Valery, 

Since RICH has been off lately and there is no indication of activity for RICH in the logbook, I'm going to go a head and do the update to the N2 cRIO to change the module reading the N2 panel supply pressure transducer. 

As per the update procedure for the cRIOs, the override switch will be used. 

A logbook entry will be posted when the update is complete. 

Best regards, 
Tyler

Hello Valery, 

We need to do a quick update to the RICH N2 cRIO hardware interlock program. The module reading out the N2 panel's supply pressure needs to be changed because it needs a different voltage source (5 V) than the other current-output sensors (24 V) used by the interlock system. 

I can see that RICH is currently powered off. Is there any conflict in doing the modifications this morning? 

Best regards, 
Tyler
