Fast commissioning / operating principle
Below you will find a short description for the initial commissioning of the BCL 308
i
. Detailed explanations
for all listed points can be found throughout this technical description.
3.1
Mounting the BCL 308
i
The BCL 308
i
bar code readers can be mounted in two different ways:
• Via four M4x6 screws on the device bottom.
• Via a BT 56 mounting device in the fastening groove on the housing bottom.
3.2
Device arrangement and selection of the 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 308
i
in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field.
• The permissible cable lengths between the BCL 308
i
and the host system depending on which inter
-
face is used.
• The correct time for data output. The BCL 308
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 and control panel should be very visible and accessible.
• For configuring and commissioning with the webConfig tool, the USB interface should be easily
accessible.
For specific information, please refer to Chapter 6 and Chapter 7.
3.3
BCL 308
i
electrical connection
For the electrical connection of the BCL 308
i
, 2 connection variants are available.
The voltage supply (18 … 30 V DC) is connected acc. to the connection type selected.
2 freely programmable switching inputs/outputs for individual adaptation to the respective application are
also available here. Detailed information on this topic can be found in Chapter 7.
NOTE
The beam of the BCL 308
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 308
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.
