4.3.7.3 Height of the scan plane
DANGER
Ineffectiveness of the protective device
Persons lying on the floor may not be detected.
b
Mount the safety laser scanner so that the maximum scan plane height is
200 mm.

Important information
WARNING
Ine
ffectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
Downstream contactors must be positively guided and monitored depending on regula‐
tions applicable at the operation site or required reliability of the safety function.
b
Make sure that downstream contactors are monitored (external device monitoring,
EDM).
WARNING
Ine
ffectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
The same safety level is required for the safety-related parts of the control which switch
the active protective field as for the safety function.
In many cases, this is safety level PL d as per ISO 13849-1 or SIL2 as per IEC 62061.
b
For position-dependent switching, use two independently wired signal sources, for
example two independent position switches.
b
For speed-dependent switching, use two independently wired signal sources, for
example two independent incremental encoders.
b
For manual operating mode-dependent switching, use a suitable manual control
switch.
