NOTICE
Distance between two control bar codes!
Ä
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 be-
tween the BPS and bar code tape and the resulting length of the scanning beam.
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:
• 30 mm with BCB G30 … bar code tapes
• 40 mm with BCB G40 … bar code tapes
NOTICE
Ä
Keep the gap between the BCBs that are switched between as small as possible.
