Tyler,

Thanks. I have no problem.Please do the needful at the earliest.

Regards

Hello Ruben and Nick, 

The new PT100s in the Torus relief valves had not been added to the LV cRIO. The program has now been updated to include the sensors. 

If all is clear, I will deploy the updated program that includes the six new PT100s this morning. 

Best regards, 
Tyler

Excellent! 

Scot - when will you get the hardware for the PT? 

Tyler - I presume you will check the cRIO for the relief valve temps? 

Have a good weekend everyone

Check that the three temperature sensors (PT100s) on the relief valves on the TST are cabled up, cables are routed to terminal blocks and LV chassis (or Cryocon), LabVIEW (if via the LV chassis) has been updated, PLC code has been updated and these sensors are displayed on the EPICS helium screen.
