Leuze BPS 34 Bedienungsanleitung Seite 19

Pertains to the MS... connector hood: only use sensors without
switching output on pin 2 or sensor cable with the assignment without
pin 2, since the switching output is not protected against feedback on the
switching input. If the inverted sensor output lies on pin 2, for example,
erroneous behavior of the switching output will result.
Bar code 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
bar codes must be used.
It must be ensured that only one control bar code is located in the scan-
ning beam at any one time. Thus, the minimum distance between two
control bar codes is determined by the distance between the BPS and
bar code tape and the resulting length of the scanning beam.
For the position calculation, the scanning beam of the BPS 34 must be
incident on the bar code tape without interruption. Ensure that the scan-
ning beam is always incident on the bar code tape when the system is
moving.
PROFIBUS:
If parameters are changed that can also be set via the PROFIBUS, they
are overwritten with the parameter setting defined in PROFIBUS after
PROFIBUS start-up. If device or module parameters are to be changed
permanently, they must be set in the PROFIBUS project.
