  The yellow LED on your SICK Accessories might be flashing because the distance between the sensor and reflector is too large, the light band isn't completely aligned, the reflector isn't suitable, or the front screen and/or reflector is contaminated. To resolve this, check the sensing range, alignment, and reflector (a SICK reflector is recommended). Also, clean the optical surfaces of both the sensor and reflector.

  If the yellow LED on your SICK Accessories doesn't light up even when aligned, it could be due to no voltage or voltage below the limit values. Check the power supply and all electrical connections (cables and plug connections). Voltage interruptions can also cause this, so ensure a stable power supply. If the power supply is OK, the sensor may be faulty and need replacement.
