If so I can check them either remotely or I can stop by the lab later as I'm going to my brothers and will be in the area for a bit. ----- Ruben Fair wrote: > Hi Pablo, > > Scot has disconnected all the cables temporarily. > > We should re-connect them within the next 15 mins. > > Also, there is a broken wire on Feed thru 8604 which Scot is trying to fix. > > Ruben > > > > From: "Pablo Campero Rojas" > To: "Ruben Fair" > Cc: "dsg-hallb magnets" > Sent: Monday, July 17, 2017 5:23:02 PM > Subject: Re: Hall B Solenoid - temperature sensors > > Hello Ruben, > > I checked the sensors that is reading back 0.0 K > > TR8671 > TR8673 > TR8611 > TR8672 > TR8674 > TR8610 > > The mentioned sensors are read by the Cryocon Units, so I have to go and check the cryocon units readouts and also make sure that the mentioned temperature sensors are physically connected in the Solenoid Service Tower. > PLC is reading 0.0 K values because the Cryocon Unit is reading a real zero (which we know is not possible at this moment) or it has a ''clip'' readback on its channels where the temperature sensors is connected (Most probably for now). > > > Best Regards, > Pablo > > > > From: "Ruben Fair" > To: "Pablo Campero Rojas" , "Probir Ghoshal" > Cc: "Scot Spiegel" > Sent: Monday, July 17, 2017 4:35:26 PM > Subject: Hall B Solenoid - temperature sensors > > Pablo, Probir, > > All the temperature sensors are now installed and the connectors are still plugged in. > > Please review all the sensors on EPICS and see if they are all reading what you expect. > > If not, please work with each other to assign correct calibration curves. > > I shall disconnect the cables first thing tomorrow morning at 7am as welding will start shortly after. > > Regards > > Ruben ></div></div><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></div></div></body></html>
