7.2.4 Cleaning further optical effective surfaces
Depending on the system equipment, further sensors with optical effective surfaces can be
installed (e. g. photoelectric reflex switch for external reading pulsing or MLG Light Grid for
detecting the object distance). Soiling of these sensors can cause incorrect switching
behaviour.
¾ In order to prevent incorrect switching behaviour, remove soiling from the optical
effective surfaces of the external sensors.
