NOTE
Select the mounting location
The distance between BPS and bar code tape must be in the working range of the
reading field curve.
Make certain that the required environmental conditions (humidity, temperature, ambi-
ent light) are maintained.
The scanning beam of the BPS should cover three or more position bar codes.
Make certain that the exit window does not become soiled, e.g., by leaking liquids,
abrasion from cardboard packaging or residues from packaging material.
BPS mounting outdoors:
Mount the BPS in a way which provides maximum thermal isolation. Mount the BPS
so that it is protected from airflow, e.g., in a protective housing.
In the event of frost on the bar code tape, no position values can be output.
In the event of direct sunlight on the bar code tape or the BPS 8 during the reading
process, no position value can be output.
The BPS 8 is designed for operating temperatures of 0°C–40°C. Beyond those oper-
ating temperatures, one can expect no position values to be output.
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 interruption. For the best functionality, the BPS must be guided parallel
to the BCB. It is not permitted to move outside of the approved working range of the
BPS (see chapter 3.3 "Reading field curves" on Page 15) while the system is in motion.
Make certain that there is only one control or marker bar code 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.
