Leuze BPS 348i - Marker Labels

Device description
Leuze electronic GmbH + Co. KG BPS 348i 24
NOTICE
If the BPS does not detect the new BCB section upon reaching the changeover position, the po-
sition-value output is dependent on the used control barcode.
MVS control barcode: The position value of the first BCB is output beyond the middle of the
MVS label for half of the label width.
MV0 control barcode: No position values are output after the middle of the MV0 label.
• When the control label is passed, the new BCB value is output relative to the middle of the device or la-
bel.

Designation: BCBG30…ML… or BCBG40…ML…
Marker labels, which are affixed at the appropriate locations on top of the barcode tape, can be used to
trigger various functions in the superior control. The BPS detects the defined marker labels in the scanning
beam, decodes them, and makes them available to the control.
NOTICE
Distance between two marker labels!
Ä Make certain that there is only one marker label (or control barcode) in the scanning beam
at a time.
The minimum distance between two marker labels is determined by the distance between
the BPS and barcode tape and the resulting length of the scanning beam.
