Resolution
T
he resolution describes the size of the smallest object detected by the safety light cur‐
tain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain.
The safety light curtain has a resolution of 30 mm. This resolution provides hand pro‐
tection.
Scanning range
The scanning range is the maximum protective field width.
The scanning range is reduced by using deflector mirrors.

3.2.2 Automatic calibration of the protective field width
When switched on, the safety light curtain automatically calibrates to the protective
f
ield width.
3.2.3 Beam coding.
Depending on its configuration, the safety light curtain operates with 1 of 3 beam cod‐
in
gs: uncoded, code 1 or code 2. The beam coding “uncoded” allows for particularly
short response times. In order to avoid mutual interference between 2 neighboring
safety light curtains, one can be operated with code 1 and the other with code 2.
