[Dsg-hallb_magnets] Torus Cernox TR817D3HB1 recovered from jumping to 325 K

[Probir Ghoshal]

Thanks Tyler,

Agreed and please be aware that for solenoid the fixed voltage set should be to 5 mV (torus have 15 mV).
Regards
Probir

Hi Tyler, 

Yes I think we can go ahead and do this for both the Torus and Solenoid. 

Let us know when it has been completed. 

Many thanks 

Ruben

Hello, 

I noted this morning that Torus Cernox TR817D3HB1 jumped to 325 K and recovered automatically one second later. This happened yesterday 62017-06-13 at ~14:24:49 PM. Attached is a MyaViewer plot of the Cernox at the time of the recovery. 

We now have recorded an instance in MyaViewer of a Cernox automatically recovering when the LV cRIO LabVIEW program only has Brian's fixed voltage subVI. It seems that the fixed voltage allows a sensor to automatically recover and prevents Cernoxes from getting stuck at 325 K. 

At this point, I think we have enough evidence that the fixed voltage allows sensors to automatically recover to make this LabVIEW version the cRIO's start-up application. Should we go ahead and set this version as the start-up app so it will automatically deploy on a reboot? 

Best regards, 
Tyler
