Hello, 
Regarding point 1 in previous email (below in blue), the parameters used at the start of the Cerenox start-up algorithm for a sensor at 325 K were incorrect. It was not using the Cerenox start-up excitation value set, but what the excitation value was before the sensor jumped to 325 K. This has been corrected. The updated LabVIEW will be deployed within the next few minutes. 

Best regard, 
Tyler 


Hello, 
This morning, I noted Torus Cerenox TR817F2 was at 325 K. The LV cRIO was restarted and TR817F2 reads ~4.8 K. 

The indicators added to LabVIEW earlier this week showed that the start-up algorithm had been running for the sensor since it first jumped to 325 K. With this new information, there are two possibilities: 

1.) How LabVIEW is running the start-up algorithm for just the Cerenox at 325K is not working correctly. I will check this today. 

2.) Just running the start-up algorithm does not fix error. When LV cRIO is restarted, there are no excitations for a few seconds. This short dead period could be what is actually fixing the error.
