Installation and application remarks
NOTICE
BCB mounting
Ä
When processing BCBs, observe the specified processing temperatures.
When processing BCBs in cold storage facilities, the BCB must be affixed before cooling the
storage facility.
However, if it should be necessary to affix the BCB at temperatures outside of the specified
processing temperature, assure that the bonding surface as well as the BCB are at the pro-
cessing temperature.
Ä
Avoid dirt deposits on the BCB.
If possible, affix the BCB vertically.
If possible, affix the BCB below an overhead covering.
The BCB must never be continuously cleaned by on-board cleaning devices such as
brushes or sponges. Permanent on-board cleaning devices polish the BCB and give it a
glossy finish. The reading quality deteriorates as a result.
Ä
After affixing the BCBs, make certain that there are no polished, high-gloss surfaces in the
scanning beam (e.g., glossy metal at gaps between the individual BCBs), as the measure-
ment quality of the BPS may be impaired.
Affix the BCBs to a diffusely reflective support, e.g., a painted surface.
Ä
Avoid sources of extraneous light and reflections on the BCB.
Ensure that neither strong sources of extraneous light nor reflections of the support on
which the BCB is affixed occur in the vicinity of the BPS scanning beam.
Ä
Affix the BCB over expansion joints up to a width of several millimeters.
The BCB must not be interrupted at this location.
Ä
Cover protruding screw heads with the BCB.
Ä
Ensure that the BCB is affixed without tension.
The BCB is a plastic tape that can be stretched by strong mechanical tension. Excessive
mechanical stretching results in lengthening of the tape and distortion of the position values.
NOTICE
BCB application
Ä
Make certain that the BCB is located in the scanning beam of the BPS over the entire
traversing path. The BPS can determine the position on BCBs with arbitrary orientation.
Ä
Bar code tapes with different value ranges may not directly follow one another.
In the case of different value ranges, a gap of at least 1 m must be maintained between the
position value of the last position bar code of the preceding BCB and the first position value
of the first position bar code of the subsequent BCB (see chapter 3.4.2 "Control bar codes").
Ä
For

/
MV0
control bar codes (see chapter 3.4.2 "Control bar codes"), the minimum dis-
tance of 1 m between the last position bar code before the control bar code and the first po-
sition bar code after the control bar code must be maintained.
Ä
For bar code tapes with different value ranges, both BCBs must correspond to the BCB type
configured in the BPS (see chapter 3.4.1 "General information").
Ä
Avoid position bar code labels with the value
00000
.
Measurements to the left of the center of a
00000
label produce negative position values
that may not be displayed correctly.
