Degas calibration

The Version 8 is a different beast but it still operates in the same general way. There is no Basic Board in a version 8 machine. The LLS (Supervisor) board has all the harness connectors for both Supervisor and Controller signals. The LLS also acts as an Analog to Digital converter. The LLC (Controller) is strictly an all digital board. Because of this, the process is thus. First, PE is situated on the bottom shelf, facing up. PE has a glass window. It is not immune to water infusion, which if that happens, can cause other damage. Next, it operates from 12V. Make sure you have 12V and ground, the third wire to the sensor is the voltage out of the sensor representing the pressure. Make sure the pins in the connector are not corroded/broken. Trace the wires to insure there are no breaks/damaged insulation, etc. That signal cable will connect directly to pins on the LLS board. Ensure that the connector is properly set to the pins. A misalignment can wipe out the LLS board. Now this is the tricky part. The signal (a voltage that will represent a pressure) from PE goes to the LLS where it is converted to a digital value for the Controller microprocessor to read. The Controller then sends that value to the motherboard to be displayed wherever necessary (i.e., Display PE pressure is required). Now, if the LLS is doing its job, then the culprit is the LLC board. But if the LLS is not working correctly... . The problem is, it is either one or the other if the sensor and harness is okay. There is no real way to say it is this one or that one. I would try a new LLC first because it is easy to replace and no calibrations are required. You will see your results immediately after you enter TSM. A new LLS will require you to download your calibration data and you most likely WILL have to re-calibrate both Temperature and Conductivity. Hope this helps.
