6.6 Distance of the reflecting surfaces
Reflective surfaces close to photoelectric safety sensors can disable the
safety function of the system.
The minimum distance (D) depends on the protective area width (I) taking into
consideration the projection and receiving angles.
The minimum distance (D) between reflective surfaces and the protected
area (P) must be observed. In case of non-respect an object to be
detected may not be detected. In case of improper handling of the product,
the safety and physical integrity of operators and machinery cannot be
guaranteed.

D = minimum distance; I = protected area width (range); P = protected area
►
After installation test by intended interruption of the protected area (P) if
reflective surfaces affect the function of the photoelectric safety sensors.
