3.2.3 Light Interference
Reflective surfaces located near the safety device may cause passive reflections. These reflections can affect the detection
of an object inside the safety zone. The passive light sources can be an incandescent lamp, sunlight, a fluorescent light, a
strobe light or other infrared light sources.
Do not install the SX5 Safety Laser Scanner near strong and/or flashing light sources.
Ambient light may interfere with the functioning safety laser scanner. If the installation requires direct exposure to ambient
light, the scanner must be positioned so that the light does not enter the output window within ±5° of the detection plane.
±5°
Figure 20. Position the scanner to avoid light interference
CAUTION: In all applications where strong light within ±5° of the detection plane cannot be avoided,
apply an additional distance to the Minimum Safety Distance calculations. This distance also depends on
the Dust Filter Level setting. See the chart below, the minimum safety distance calculation section
(
Minimum Safety (Separation) Distance Formula
on page 30), and the dust filtering section (
on page 28).
