6.2.2 Orientation of the BPS to the bar code tape
The beam of the BPS must be oriented at an incline of 7° to the bar code tape (see figure 6.9). When posi
-
tioning, make certain that the angle of radiation to the rear side of the housing is 90 ° and the reading
distance to the bar code tape is maintained.
NOTICE
Select the mounting location.
Make certain that the required environmental conditions (humidity, temperature) are maintained.
Make certain that the distance between BPS and bar code tape is sufficiently large.
The scanning beam of the BPS should cover three or more bar codes.
The distance between BPS and bar code tape must be in the working range of the reading field curve.
Make certain that the exit window does not become soiled, e.g., by leaking liquids, abrasion from
cardboard packaging or residues from packaging material.
Mounting the BPS outdoors or with BPS with integrated heating:
Mount the BPS in a way which provides maximum thermal isolation, e.g., using rubber-bonded metal.
Mount the BPS so that it is protected from airflow, e.g., in a protective housing.
Mounting the BPS in a protective housing:
When installing the BPS in a protective housing, ensure that the scanning beam can exit the protective
housing without obstruction.
Make certain that the scanning range determined from the scanning curve is adhered to at all locations
where a position determination is to be made.
Ensure that the scanning beam is always incident on the BCB when the system is moving.
For the position calculation, the scanning beam of the BPS must be incident on the BCB without inter
-
ruption.
For the best functionality, the BPS must be guided parallel to the BCB. It is not permitted to move out
-
side of the approved working range of the BPS (50 … 170 mm) while the system is in motion.
Make certain that there is only one control bar code (or marker label) in the scanning beam at a time.
The minimum distance between two control bar codes is determined by the distance between the BPS
and bar code tape and the resulting length of the scanning beam.
NOTICE
For parallel mounting, maintain the minimum distance!
Maintain the minimum distance of 300 mm if you mount two BPS next to or above one another.
NOTICE
Install the connection hood before mounting the BPS!
Tighten the screws on the connection hood with a tightening torque of 1.4 Nm.
