Maximum and minimum monitoring height
The number of LEDs is limited to 510. This results in different maximum monitoring
heights depending on the beam separation. The minimum monitoring height is deter‐
mined by the beam separation and the smallest module size for this beam separation.
Beam separation Maximum monitoring height Minimum monitoring height
2.5 mm 1195 mm 145 mm
5 mm 2,545 mm 145 mm
10 mm 3,140 mm 140 mm
20 mm 3,130 mm 130 mm
25 mm 3,125 mm 275 mm
30 mm 3,1320 mm 270 mm
50 mm 3,100 mm 250 mm

3.4.5 Teach-in
During the teach-in process, the switching thresholds for all beams are individually
adjusted for the sensing range and the ambient conditions.
After teach-in has been completed, it must be ensured that the setup is no longer
changed otherwise another teach-in will have to be carried out.
The MLG-2 Pro provides the following options for carrying out a teach-in:
•
Pressing the teach-in button
•
Automatic teach-in (when switching on)
•
Signal at a switching input
•
SOPAS ET
•
IO-Link
•
Webserver
Teach-in quality
The teach-in quality indicates the quality after the teach-in process. The MLG-2 calcu‐
lates this value based on the quality of the light level received. The teach-in quality
depends on the alignment of the MLG-2 and the cleanliness of the front screens.
The value remains constant until another teach-in process is carried out.
