Removed temporary PLC logic program that was used to monitor the temporary vacuum gauge on CG8606. <br>2. Wiring for temporary gauge was removed from the terminal block in the controls rack to connect actual vacuum gauge signal CG8606. <br>3.Verified correct assignation in the PLC analog input channels (0-10 V) for three vacuum signals (CG8606, CG8600TB, and TB8600) <br>4. The connector hooked in Turbo pump TC-1200 remote was modified, pin 1 (+24VDC) was disable to avoid turning on of the turbo pump, This remote option not required by our control system; connector only used to monitor the speed in the turbo pump (pin 12: 0-10 V output). <br>5. Verified wiring (continuity and sense) for the three signals. <br>6. Measured voltage in the terminal block to make sure the PLC analog input operation range 0-10 V. <br>7. Actual readouts for the vacuum signals were compared between hardware vacuum controllers and the readouts on the Solenoid control systems (PLC and EPICS). The initial readouts as follow: <br>Vacuum signal <br>Pfeiffer DCU-002 Unit - Turbo Pump <br> Pfeiffer TPG-362 - Vacuum controller PLC/EPICS <br>CG8606 <br> 4.27 [torr] 4.191 / 4.18 [torr] <br>CG8600TB <br> 1.51*10^-2 [torr] 1.512*10^-2 / 0.01 [torr] <br>TB8600 0 % <br> 0.101 / 0.10 % <br><br>Best Regards, <br>Pablo<br></div></div><br>_______________________________________________<br>Dsg-hallb_magnets mailing list<br>Dsg-hallb_magnets@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets<br></blockquote></div><br><div>-- <br></div><div>George</div></div><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>
