[dsg-svt] SVT outinhibit

[Peter Bonneau]

Yuri:

I checked on the hardware interlock system system this morning and it's 
running normally (no trips overnight).

After a system trip and before resetting, we need screen captures of the 
"Interlock Status and signal monitoring" and the "Raw data monitoring" 
tabs of the Hardware Interlock Monitoring System user interface for 
troubleshooting. We need to know which signal is causing the tripping.

The last time we had an issue like this (1/31/2017) ,  the problem was 
caused by a loose connection to the  external coolant system monitoring 
electronics  (Proteus Industries sensor and Florite 990x Controller.)

As mentioned back in January, we don't have spares for the external 
coolant monitoring electronics. I recommend we purchase spares for this 
system.
