Hello Pablo,
Thanks for your list of items and questions.
I will work on this list and see who and when can provide all this information to you.

Thanks
Renuka

Hello Renuka, Nick. 



The following is a list of items and question, that I need in order to complete the Solenoid PLC programs: 



1. Calibration data for Temperature sensor that will be used in Cryocon Monitor temperatures. 

2. Power on and establishing Ethernet connection for the three Cryocon units, I need to download the calibration data. 

3. Mapping (layout) with the locations of temperature sensors in Solenoid Cryocon #3. 

4. Solenoid Voltage Tap Calculation for the Comparators. 

5. Define Process Variable (PV_Array) that will be share between DBX-Torus- Solenoid. 

6. Confirm formula to be used to calculate the He_Liquid_Level tank in percent based on DP measurements for Lead Reservoir 

7. Confirm formula to be used to calculate the He_Liquid_Level tank in percent based on DP measurements for Magnet Reservoir. 

8. I need the model and specs of the Heaters HTR-8620 (Lead Heater Reservoir) and HT 8672 to confirm scale factor and read Voltage and Current and make the calculation for output signal. 

9. Max Engineering units limit to be implemented for heater HTR 8620 and HT 8672. Will we use them as the Torus does? 

10.The Solenoid vacuum system requires being implemented timer delays to avoid spoiled vacuum readings. How long is it in the Torus? I discussed with George and he recommended take the same as the Torus does. 

11. Threshold Limits for Process variables that are part of the Magnet Interlocks need to be defined. 



We discussed some of these points today during the PLC Programming Solenoid meeting, and I will met with Nick tomorrow morning to work on these. 



Best Regards 

Pablo Campero
