Procedure:
• Examine the mounting surface. It must be flat, without warping, free of grease and
dust, and dry.
• Define a reference edge (e.g. metal edge of the busbar)
• Remove the backing and affix the BCT along the reference edge
tension free
.
Secure the BCT to the mounting surface by pressing down with the palm of your
hand. When affixing, make certain that the BCT is free of folds and creases and that
no air pockets form.
• Never pull the BCT. Because this is a plastic tape, forceful pulling may stretch it. This
results in a distortion of the measurement units on the tape. While the BPS 34 can
still perform the position calculation, the accuracy in this case is no longer ensured. If
the values are taught using a teach-in process, distortions are irrelevant.
• Expansion joints with widths up to several millimetres can simply be covered with the
barcode tape. The tape must not be interrupted at this location.
• Protruding screw heads can simply be taped over. Cut out the bar code which covers
the screw head at the cut marks.
• If the application dictates the necessity of a gap, the tape is to be affixed over this gap
and the affected cut marks cut out. If the gap is small enough that the scanning beam
can detect the label to the left or to the right of the gap, measurement values are
delivered without interruption. If the scanning beam cannot completely scan any label,
the BPS 34 returns the value 0. As soon as the BPS 34 can again scan a complete
label, it calculates the next position value.
• The maximum gap between two barcode positions without affecting the measurement
value is 40 mm.
Notice!
If the barcode tape was damaged, e.g. by falling parts, a repair kit can be downloaded from
the Internet (www.leuze.de -> Under the heading Download ->

Attention!
Barcode tapes with different value ranges may not directly follow one another. If the value
ranges are different, the gap between the two BCTs must be greater than the detection
range of the scanning beam or control barcodes must be used (for further information see
chapter 6.4 on page 32).
Notice!
When working with the BCT in cold warehouses, it should be ensured that the BCT be af-
fixed before the warehouse is cooled. However, if it should be necessary to work with the
BCT at temperatures outside of the specified processing temperature, please make certain
that the bonding surface as well as the BCT are at the processing temperature.
