What to do if yellow LED does not light up on SICK Accessories?
- WwriveraAug 3, 2025
If the yellow LED on your SICK Accessories isn't lighting up, even when the light beam is aligned and the object is within range, there might be a few reasons. First, check the power supply and all electrical connections, including cables and plugs, to ensure they are properly connected. Second, voltage interruptions may be the cause, so ensure a stable power supply without interruptions. If the power supply is confirmed to be working correctly, the sensor may be faulty, and you should replace it.
