  If the yellow LED on your SICK Accessories device doesn't light up even when the light beam is aligned and the object is within range, there might be a few reasons: * There could be no voltage or the voltage might be below the required limit. Check the power supply and all electrical connections, including cables and plugs. * There might be voltage interruptions. Ensure a stable power supply. * The sensor itself might be faulty. If the power supply is confirmed to be working, consider replacing the sensor.

  If an object is blocking the beam path but there's no output signal from your SICK Accessories, the test input might not be connected properly. Double-check the connection of the test input. If you're using female cable connectors with LED indicators, ensure the test input is correctly assigned.

  If the yellow LED is flashing on your SICK Accessories, it indicates that the sensor is ready for operation, but the operating conditions aren't ideal. To resolve this: * Ensure the light beam is completely aligned on the object. * Clean the optical surfaces. * Check the sensing range and adjust it if necessary.

  If an object is in the path of the beam, but the yellow LED doesn't light up on your SICK Accessories, it might be because the distance between the sensor and the object is too long, or the sensing range is set too short. Try increasing the sensing range.

  If the yellow LED lights up even when there is no object in the path of the beam for your SICK Accessories, the sensing range distance might be too large. Try reducing the sensing range.
