Alignment/Adjustment

Note!
Mounting Code Sheets on the OIT300, OIT500, and OIT1500
Ensure that the code sheet is mounted perpendicular to the camera lens in the
OIT system housing. A maximum tilt angle of 10° applies; this angle must not be
exceeded.
Illumination angle
To optimally detect the matrix of holes, the code carriers must be illuminated by
the LED board from a specific angle that achieves the greatest possible contrast
between the holes and the metal plate. The angle of correct illumination must be
set based on the reading distance. The illumination unit is attached to a rail in the
housing of the OIT system and can be slid to the correct position based on a
scale.
The OIT200 system is preset to a distance of 170 mm between the read-only tag
and OIT system
The OIT300 system is preset to a distance of 200 mm between the read-only tag
and OIT system.
The OIT500 system is preset to a distance of 380 mm between the read-only tag
and OIT system.
The OIT1500 system is preset to a distance of 1500 mm between the read-only
tag and OIT system.
If you will be using this distance, you can disregard the following settings see
chapter 5.2.
Setting optimal illumination angle
In order to set the optimal illumination angle, proceed as follows:
1. Unscrew the OIT enclosure cover.
2. Loosen the 2 screws at the base of the illumination unit (see Position 1).
Figure 6.1
3. Slide the illumination unit to the same distance as the OIT to the read-only tag
(see Position 2). The number on the dial will correspond to the distance from
the read-only tag in mm. Align the screw that is closest to the camera
(the left screw in the picture above) so that it is in line with the dial. The
further the illumination unit is from the camera system, the greater the read
distance.
4. Once the correct distance has been set, tighten the screws at the base of the
illumination unit.
5. Screw the OIT enclosure cover back down.
