Installation and mounting

BCL 338

Leuze electronic
Note!
When mounting, ensure that the scanning beam is not reflected directly back to the scanner
by the label which is being read. For further information, see the notices in Chapter 6.3!
Please refer to Chapter 5.4 for the permissible minimum and maximum distances between
the BCL 338
i
and the labels to be read.

Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the bar codes on the objects to be
scanned.
• The reading field of the BCL 338
i
in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading
field (see chapter 5.4 "Reading field curves / optical data").
• The permissible cable lengths between the BCL 338
i
and the host system depending
on which interface is used.
• The correct time for data output. The BCL 338
i
should be positioned in such a way
that, taking into consideration the time required for data processing and the conveyor
belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of the
read data.
• The display elements such as LEDs or the display should be highly visible.
• For configuring and commissioning with the webConfig tool, the USB interface should
be easily accessible.
For specific information, please refer to Chapter 6.
Note!
The beam of the BCL 338
i
exits:
•
Parallel
to the
housing base
in the case of the line scanner
•
At
105 degrees
from the
housing base
in the case of the deflecting mirror
•
Perpendicular
to the
housing base
in the case of the oscillating mirror
In each case, the housing base is the black area in Figure 6.2. The best read results are
obtained when:
•
The BCL 338
i
is mounted in such a way that the scanning beam is incident on the bar
code at an angle of inclination greater than
±10° … 15°
to vertical.
• The reading distance lies in the middle area of the reading field.
• The bar code labels are of good print quality and have good contrast ratios.
• You do not use high-gloss labels.
• There is no direct sunlight.
