[Dsg-hallb_magnets] request to stop Torus LV cRIO for debugging on morning of 2016-01-04

[Tyler Lemon]

Hello Dave Kashy, 

Can the Torus LV cRIO be taken offline tomorrow morning for a few hours to debug bad Load Cell readings? 

The debugging would be to find the cause of the bad Load Cell Values that occurred after Brian Eng made changes to the LV cRIO in November 2016 (HBTORUS Logbook entry #3438123). 

Today, at about 2:00PM, Ruben gave his okay and requested you to also approve the cRIO downtime. Please let me know if there are any tests occurring tomorrow morning where the Torus LV cRIO should not be stopped. 

Best regards, 
Tyler

Hi Tyler, 

Yes - most probably but please check with Dave Kashy first.

Hello Ruben, 

In November, Brian made changes to the Torus LV cRIO that had to be rolled back because of issues with nonsense Load Cell readings. These issues were noted in HBTORUS Logbook entry # 3438123. 

Can the Torus LV cRIO be taken offline this afternoon for a few hours to debug the bad Load Cell readings? 

Best regards, 
Tyler
