Hello Ruben, 

No, I did not get any response from Dave yet.

Pablo, 

Have you had all your questions addressed by Dave yet? 

He should be back in the office either tomorrow or Thursday this week.

Hello Dave, 

Looking into the ' PID Setup and Check Off' spreadsheet used for the Solenoid Cool-down. I noticed that there are a valve that appears with the names PV8653C and PV8653C.MAX. 

Are these names a typo error on the spreadsheet ? and maybe they are making reference to the valve PV8563C on the DBX used to (80K) Supply Helium for the Solenoid? 





The same valve PV8653 also appears on page 12 (as PV8653W ) and 14 (As PV8653C and PV8653) in the 'B000000900-P001 CLAS12 Solenoid Coodown and Operation Procedure r2' document. 

I also checked the P&I D cryogenics for the DBX and Solenoid and I can't find the valve PV8653. 

Please, can you clarify this, so that I can complete with the verification of the all PID and Cascading PID loop in the Solenoid and DBX PLCs 

Best Regards, 
Pablo
