SICK SLG-2 User Manual

NOTE
If the installation is not counter-rotating, make sure that there is a minimum distance
between the two light grids, which can be taken from the following diagram:
Figure 11: Minimum distance between 2 SLG-2 light grids
NOTE
If more than two SLG-2 light curtains are used, the FlexChain system with cascadable
SLG-2 light grids is recommended.
4.4 Alignment
When mounting, the sender and receiver must be aligned as accurately as possible.
Absolute accuracy r of the alignment depends, among other things, on sensing range d
and can be calculated with availability angle α . This availability angle is 4.5°.
r = tan (α)*d

NOTE
An alignment aid is available via IO-Link and SOPAS ET for precise alignment of the light
grids. The description can be found in chapter chapter 7.5.1.
4.5 Mounting the light grid
The SLG-2 is available in a flat version (light emission on the wide side) and a slim
version (light emission on the flat side). Mounting must be done properly.
NOTE TIP
Light emission of the light grid is always on the side of the optics front where there is no
label.
