13. Inspection and service
13.1. Functional checks
Important!
Functional checks should be performed at certain intervals (e.g. daily). Pay attention to the results of
the risk analysis here.
The functional check is performed using an appropriate test object.
NOTICE
The test object must be suitable for the resolution of the device.
1. Move the test object into the protected area from above.
2. Observe the red LED on the receiver unit. This LED must illuminate red continuously after the initial
interruption. The state of the LED is not allowed to change during the check.
3. Move the test object through the protective field. Follow the dotted line in the graphic.
4. After a successful test, return your system to normal operation.

13.2. Cleaning
Regular cleaning of the optical surfaces is recommended. The interval is dependent on the ambient conditions and the
degree of contamination in the place of use.
Cleaning must be performed using a clean, damp cloth.
Important!
Do not use any abrasive or caustic products, e.g. solvent or alcohol. These could damage the optical
surfaces.
Also avoid woolen cloths to prevent electrostatic charging of the surface.
Ambient conditions with abrasive dust require careful cleaning of the system.
