5. Installation
Cautions during the installation of SE2L are explained in this chapter.
5.1 Light interference
SE2L uses pulsed laser for object detection. Light sources in the surrounding could interfere with its
operation leading to false detection. User should examine the surroundings environments before installing
the SE2L. Some of the light sources that could interfere with SE2L are as below.
 Incandescent light
 Fluorescent light
 Stroboscopic light
 Flashing beacon
 Sunlight
 Infrared light sources
In case the light source cannot be avoided during the operation, SE2L should be installed with the light
source located at ±5 degrees or more from the detection plane to prevent the interference (Figure 5-1).
