Arrangement of the control barcodes
The control barcode is attached in such a way that it replaces one position barcode or seamlessly con-
nects two barcode tapes with different value ranges to one another.
A position label does not need to follow immediately after the MVS or MV0 control bar code. For an uninter-
rupted measurement value determination, a gap less than or equal to one label width (40 mm) may be
present between the control bar code and the subsequent position label.
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.
