[Dsg-hallb_magnets] Solenoid PLC Programming

[Pablo Campero]

Hello Ruben, 
I started making progress with the information provided by Dave and Nick about the formula use to calculate the Helium_Liquid_Level(points 6 and 7). 

Thanks Renuka for the list with the reference. 


With Regards 
Pablo

Hello Ruben, 
I started this list. This file is located in the folder "M:\hallb_eng\CLAS12\Magnets\Solenoid\Controls and Wiring". 

Dave, George and Scot, could you please have a look at this list and let me know if you can provide the information, or it has to be provided by someone else. 

Pablo, please let me know if anything missing there. 

Thanks 
Renuka

Renuka, Pablo, 

Are you making progress with the list of questions below from Pablo? 

Regards 

Ruben

Renuka, 

You may want to start a 'punch-list' and add these items to it and then chase individuals to ensure they are talking to each other and sharing and providing information.

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
