Approach
1.
Carry out the test for the relevant preset monitoring case.
2.
Check the mechanical installation to ensure that all fixing screws are secure and
that the safety laser scanner is properly aligned.
3.
Check each safety laser scanner device for visible changes such as damage,
manipulation etc.
4.
Switch on the machine/system.
5.
Watch the LEDs on each safety laser scanner.
6.
If not at least one LED of each safety laser scanner is permanently illuminated
when the machine/system is switched on, it is to be assumed that there is a fault
in the machine or system. In this case the machine must be shut down immedi‐
ately and checked by qualified safety personnel.
7.
To test the protective function for the entire system, deliberately interrupt the pro‐
tective field while the machine is running.
The LEDs of the safety laser scanner must change from green to red and the dan‐
gerous movement must stop immediately.
If the safety laser scanner with the protective field that you are interrupting
switches the OSSDs on another safety laser scanner or the OSSDs on a sens:Con‐
trol series via EFI, then on this device the LEDs must change from green to red and
the dangerous movement on the machine or system connected must come to an
immediate stop.
8.
Repeat this test at different points in the hazardous area and on all safety laser
scanners.
If any non-conformance of this function is discovered while doing so, the machine/
system must be shut down immediately and checked by qualified safety person‐
nel.
9.
For stationary applications, check that the hazardous areas marked out on the
floor match the shapes of the protective fields stored in the safety laser scanner
and that any gaps are protected by additional protective measures.
In the case of mobile applications, check that the moving vehicle actually stops at
the protective field boundaries which are set in the safety laser scanner and listed
on the information label in the vehicle or in the configuration protocol. If any non-
conformance of this function is discovered while doing so, the machine/system
must be shut down immediately and checked by qualified safety personnel.
10. If the reference contour monitoring feature is used, check the areas with the refer‐
ence contour:
°
Move the test object along the inner edge of the tolerance band of the refer‐
ence contour. The safety laser scanner must detect the test object at each
position and indicate the detection.
°
If several reference contours are used, test all reference contours.

Cleaning the front screen
Overview
The safety laser scanner is largely maintenance-free. The front screen on the safety
laser scanner should however be cleaned regularly and also if contaminated.
