Note
If the light of the scan line falls exactly vertically on the surface of the bar code, disturbing
reflections can occur when the reflected light is received. In order to avoid this effect the
CLP 100 must be installed so that the emitted light is tilted relative to the perpendicular
(
refer to Figure 4-5

Installation and adjustment of the device
4.3.1
Installing the CLP 100
1. Align the CLP 100 so that the angle between the scan line and the bar code bars
amounts to 90
°
. Take any possible reading angle occurring into consideration (
refer to
Figure 4-4
2. In order to avoid disturbing reflections align the CLP 100 so that the emitted light impacts
on the bar code at an angle of 100
° respectively
95
°
(
).
Damage to the housing
The screws may not be screwed more than 5 mm into the CLP 100. Longer screws may
damage the housing.
¾
Use screws with a suitable length.
3. Screw the screws through the base to which the CLP 100 is fastened into the threaded
hole.
4. Tighten the screws slightly.
5. Adjust the CLP 100 as described below.
