Fast commissioning

3 Fast commissioning
Below you will find a short description for the initial commissioning of the BCL 248i. Detailed explanations
for all listed points can be found throughout these operating instructions.
3.1

Mounting

The bar code reader can be mounted in the following ways:
• Mounting with four M4x5 screws on the rear side of the housing.
• Mounting with mounting devices on the fastening groove on one side of the housing.
3.2

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 bar code reader in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field with the re-
spective module width (see chapter 13.2 "Reading fields").
• alignment of the bar code reader for avoiding reflections.
• Distance between bar code reader and host system with respect to the interface.
• The correct time for data output. The bar code reader 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 should be highly visible.
• For configuring and commissioning with the webConfig tool, the HOST interface should be easily ac-
cessible.
For further information, see see chapter 5 "Mounting" and see chapter 6 "Electrical connection".
The best read results are obtained if the following prerequisites are fulfilled:
• The reading distance lies in the middle area of the reading field.
• There is no direct sunlight and protect against ambient light effects.
• The bar code labels are of good print quality and have good contrast ratios.
• You are not using high-glossy labels.
• The bar code is moved past with an angle of inclination of ±10° ... 15° to vertical.
NOTICE
Avoid direct reflection of the laser beam!
The beam on the bar code reader is emitted at 105° to the housing base. An angle of incidence
of 15° of the laser to the label has already been integrated in the deflecting mirror so that the bar
code reader can be installed parallel to the bar code (rear housing wall).
3.3

Electrical connection

The bar code reader is equipped with two connection cables, each with an M12 connector.
• PWR/SWIO: M12 connection for supply voltage and switching input/output, 5-pin, A-coded, cable
length 0.9 m (unshielded)
• HOST: M12 connection for Ethernet/PROFINET, 4-pin, D-coded, cable length 0.7 m (shielded)
