What to do if the yellow LED doesn't light up on my SICK Accessories?

If the yellow LED on your SICK Accessories does not light up, even when the light beam is aligned with the reflector and there are no obstructions, it could be due to insufficient or absent voltage. Check the power supply and all electrical connections, including cables and plugs. Another potential cause is voltage interruptions; ensure a stable, uninterrupted power supply.
