[Dsg-hallb_magnets] Tested Vaporizer instrumentation

[Brian Eng]

We also tested and confirmed that the 3 solenoid Cryo-con units will cause the EPICS screen to indicate a failure when the unit loses power.

However, if the on/off button is pushed on the units it won't cause an error because the units will still be alive on the network and return the last read temperatures, but the values will never change.
