What to do if all the bar graph indicators flash on and off on my Nexen GC300?
If all the bar graph indicators on your Nexen Controller flash on and off, this indicates a limit switch problem. For example, there may be no limit switches connected to J2 pins 3, 4, and 5, or a missing common connection to the limit switches. To resolve this, check the wiring from J2 pins 3, 4, 5, and 6 to the limit switches.
Why the bar graph indicators on Nexen Controller don't reflect web position?
If the bar graph indicators on the GC300 front panel of your Nexen Controller do not reflect the web position when using the sensor connected to the Second Sensor Board, it could be due to incorrect sensor connections. The electrical connections of the sensor on the Second Sensor Board differ from those on the GC300 main circuit board. Verify the electrical connections between the sensor and the GC300 Main Control Board.
How to enter CPC mode on Nexen GC300 Controller if the Sensor key doesn't work?
If you cannot enter CPC mode on your Nexen Controller by pressing the Sensor key, the Second Sensor Board may not be recognized by the GC300. This can be caused by a bad connection between the GC300 and the Second Sensor Board. To fix this, turn off the GC300, check all connections between the GC300 and the Second Sensor Board, and then power up the GC300 again.
What to do if the green indicator is always lit on Nexen Controller?
If the green indicator on the Main Control Board of your Nexen Controller is always lit (normally, it is always off), it means that Sw2-3 is set to On. To correct this, set Sw2-3 to Off.
