[Dsg-hallb_magnets] Solenoid VT monitoring

[Ruben Fair]

Pablo, 

The latest thresholds and how the QD's monitor individual and summed voltages are defined in the usual spreadsheet on the M drive - by all means please have a look at it. 

It is still not clear (to me at least) which voltage tap tripped the interlock. I am still looking at the data as it is not at all clear why QDSUM1 tripped when the thresholds are now set so high.

Hello Probir, 

DSG noticed during the last Solenoid fast dump (02/19/2018) that voltage taps SUM values did not exceed the set thresholds on the QD1. 
Are the QDs supposed to look at the SUM of the voltage tap combinations values or the QDs are configured to check the voltage tap values individually to then compare with the set thresholds? 
Which voltage tap/s generated the last Solenoid fast dump? 

Regards, 
Pablo
