What to do if yellow LED does not light up on SICK W34?
- JJack McgeeAug 12, 2025
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.
