Controllable Functions - Leuze electronic BPS 34 Technical Description

Leuze electronic
For error-free function, when using control barcodes it must absolutely be ensured that the
distance between the BPS and barcode tape is selected large enough. The scanning beam
of the BPS should cover three or more barcodes; this is ensured at a distance which lies in
the working range of the reading field curve.
The control barcodes are simply affixed over the existing tape. When affixing the control
barcodes, make certain to cover entire barcodes to ensure that a barcode spacing of 4 cm
is maintained.

Measurement value switching between 2 barcode tapes with different value
ranges
The "MVS" control barcode is used to switch between two barcode tapes. The end of one
tape and the start of the next can end and begin, respectively, with completely different posi-
tion barcodes. If the centre of the BPS 34 reaches the transition point of the control barcode,
the device switches to the second tape, provided the next position label is in its scanning
beam. As a result, the output position can always be uniquely associated with one tape.
