    Why is the green LED not lighting up on my SICK Accessories?
    • M
      Mark WoodsJul 29, 2025
      The green LED might not light up on your SICK Accessories due to several reasons: * There could be no voltage or the voltage might be below the acceptable limit. In this case, check the power supply and all electrical connections, including cables and plugs. * Voltage interruptions may occur. Ensure a stable power supply. * The sensor itself might be faulty. If you've confirmed the power supply is working, consider replacing the sensor.
