My apologies, I realized I sent this from my person email so I am sending it again to ensure it gets though the mailing list system. 

Ruben, 

The following is a status update on the DSG work on the torus interlock checkout procedure. 

This afternoon, October 3 ,2016, we were not able to perform any tasks on the interlock checklist. There were issues with noise in voltage taps that are causing the interlock to constantly trip. We worked on this issue in Hall B and could see the noise in the voltage taps causing the issues in EPICS. 

Tomorrow at 800AM we plan to meet with Krister to perform the tasks for the interlock cable check because he is able to use the man lift. 

We still have to perform all other tasks on the list because we have yet to verify that the dump contact trips in the MPS because until today, there were still interlocks present and there was still work being done on the quench detection system. 

Best regards, 
Tyler
