Device description
Leuze electronic BPS 307i 22
1 Control bar code
2 End of position determination from the middle of the control bar code
Figure 3.11: Arrangement of the MV0 control bar code
The control bar codes are simply affixed over the existing bar code tape.
A control bar code should cover an entire position bar code and must have the correct grid dimension (see
figure 3.12):
• 30 mm with BCB8 bar code tapes
• 40 mm with BCB bar code tapes
NOTICE
Distance between two control bar codes!
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.
Keep the gap between the BCBs that are switched between as small as possible.
