Hello Dave, 

Thank you for your comments. I will work on them as soon as possible. 

Best Regards,

Hi Pablo, 

I skimmed your slides and here are some comments. 

Slide 5: The last note says all sensors ... are controlled... 
Is this really true? Do we have limits for all sensors? For example, the LL sensors during initial cooling are not used. You might get a question on this so having details will be helpful 

Slide 6: Do you have sensor sample rate tables? (which are fast and which are slower and the actual rates?) 

Slide 9: The descriptions in the epics screen need to be filled in 

Slide 10: When you say Cascading PID loops will be added... do you mean that the PLC/epics programing is not complete or that the control variables and PID parameters are not setup? Also the reason for Cascade PID's is to allow a single control element (valve/heater) to be controlled by multiple system variables vs just one) 

Slide 11: Different control setups are required for many elements depending on the stage/phase of operation, this is more than setpoints. Example: a valve may be in manual mode in phase 1 and PID mode in phase 2 or the control input parameter may be different in a different phase. 


Slide 12: Do we have a roots pump on the solenoid? 


Slide 14: Thresholds were not received from ETI. JLab determined these( see my talk). 

Slide 16: Need to check values, I think we have deleted the first requirement. Also we may need to increase the helium to metal values to achieve a reasonable CD rate. (see temperature plot in my talk...) 


Slide 19: Do we have a list of not completed screens? Load Cells line should be highlighted. 



Dave

Hello Ruben, 

I have added 1st draft versions of the presentations (Solenoid I & C Cooldown and Solenoid I& C Power up) in the folders that you have indicated. 

Best Regards, 
Pablo

Thank you Dave. 

All, 

Please have a look through all the draft presentations presently in the cool down and power up ERR presentation folders over the next few days. And send your comments directly to the presenter. 

I shall arrange for a dry run shortly.
