Calibration data for Temperature sensor that will be used in Cryocon Monitor temperatures. <br><br>2. Power on and establishing Ethernet connection for the three Cryocon units, I need to download the calibration data. <br><br>3. Mapping (layout) with the locations of temperature sensors in Solenoid Cryocon #3. <br><br>4. Solenoid Voltage Tap Calculation for the Comparators. <br><br>5. Define Process Variable (PV_Array) that will be share between DBX-Torus- Solenoid. <br><br>6. Confirm formula to be used to calculate the He_Liquid_Level tank in percent based on DP measurements for Lead Reservoir <br><br>7. Confirm formula to be used to calculate the He_Liquid_Level tank in percent based on DP measurements for Magnet Reservoir. <br><br>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. <br><br>9. Max Engineering units limit to be implemented for heater HTR 8620 and HT 8672. Will we use them as the Torus does? <br><br>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. <br><br>11. Threshold Limits for Process variables that are part of the Magnet Interlocks need to be defined. <br><br><br><br>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. <br><br><br><br>Best Regards <br><br>Pablo Campero <br><br>_______________________________________________ <br>Dsg-hallb_magnets mailing list <br>Dsg-hallb_magnets@jlab.org <br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets</div></div><br></div></div></body></html>
