CAUTION
Pertains to the MS... connector hood: only use sensors without switching out-
put on pin 2 or sensor cable with the assignment without pin 2, since the switch-
ing 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 scanning 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 scanning beam is
always incident on the bar code tape when the system is moving.
CAUTION
PROFIBUS:
If parameters are changed that can also be set via the PROFIBUS, they are over-
written 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.
