Why can't I access programming on my red lion PXU100B0?
If you cannot access programming on your Red Lion Controller, it could be because an active User Input is programmed for PLOC; deactivate the User Input. Alternatively, you may have entered an incorrect access code. Enter the proper access code at the CodE 0 prompt (111 or -111 is the universal access code).
Why is there no display on my red lion PXU100B0 Controller?
If there is no display on your Red Lion Controller, it could be due to several reasons. First, check if the power is off. Second, a brown-out condition might be present, so verify the power reading. Third, there might be a loose connection or improper wiring, so check all connections. Lastly, ensure the controller is fully seated into the case by checking the installation.
What to do if Red Lion Controller shows '????' in the top display?
If your Red Lion Controller displays '????' in the top display, it could be due to several reasons. It may be that the input exceeds the range of the controller, so check the input parameters. Alternatively, the temperature might exceed the range of the input probe, so change to an input sensor with a higher temperature range. Also, the transmitter or probe could be defective or incorrect, so replace them. Finally, the temperature may be too high for the probe, so reduce the temperature.
What to do if Red Lion Controller shows ' . . . ?. . .' or 'IN' in display?
If your Red Lion Controller displays ' . . . ?. . .' or 'IN', it might be because the display value exceeds the 4-digit display range, so check the input parameters. Another reason could be a defective or miscalibrated cold junction circuit, so change the display resolution or scaling.
Why is my red lion PXU100B0 sluggish or not stable?
If your Red Lion Controller is sluggish or not stable, it could be due to incorrect PID values. Also, the probe location could be incorrect; evaluate its placement.
What to do if Red Lion Controller shows '????' in display?
If your Red Lion Controller displays '????' in the display, it could be due to a disconnected probe, so check the probe wire or change the probe. Another reason might be a broken or burned-out probe, so check the sensor input type selection.
What to do if Red Lion Controller shows '????' in top display?
If your Red Lion Controller displays '????' in the top display, it could be because the input is below the range of the controller, so check the input parameters. It may also be that the temperature is below the range of the input probe, so change to an input sensor with a lower temperature range. Also, the transmitter or probe could be defective or incorrect, so replace the transmitter or probe. Finally, the temperature may be excessively low for the probe, so raise the temperature.
