There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
NOTE
Affix laser information and warning signs!
Laser warning and laser information signs are affixed to the device (see Figure 2.1):
In addition, self-adhesive laser warning and information signs (stick-on labels) are supplied
in several languages (see Figure 2.2).
Affix the laser information sheet to the device in the language appropriate for the place
of use.
When using the device in the U.S.A., use the stick-on label with the "Complies with
21 CFR 1040.10" notice.
Affix the laser information and warning signs near the device if no signs are attached
to the device (e.g., because the device is too small) or if the attached laser information
and warning signs are concealed due to the installation position.
Affix the laser information and warning signs so that they are legible without exposing
the reader to the laser radiation of the device or other optical radiation.

Fast commissioning / operating principle
3 Fast commissioning / operating principle
Below you will find a short description for the initial commissioning of the BCL 338i. Detailed
explanations for all listed points can be found throughout this technical description.
3.1 Mounting the BCL 338i
The BCL 338i 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 338i 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 338i and the host system depending
on which interface is used.
• The correct time for data output. The BCL 338i 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.
Note!
The beam exits the BCL 338i as follows for the respective devices:
- line scanner parallel to the housing base
- deflecting mirror 105 degrees to the housing base
- oscillating mirror perpendicular to the housing base.
The black areas in Figure 6.2 are the housing base. The best read results are obtained
when:
• The BCL 338i 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.

3.4 BCL 338i on the EtherCAT
3.4.1 Device description file
For EtherCAT, all process data and parameters are described in objects. The compilation
of all process data and parameters of the BCL 338i - the object directory - is stored in a socalled ESI file (EtherCAT Slave Information).
The ESI file contains all objects with index, sub-index, name, data type, default value,
minimum and maximum, and access possibilities. That means the ESI file describes the
entire functionality of the BCL 338i.
The ESI file has the name BCL338i.xml and is available for download on the Leuze home
page.
Vendor ID for the BCL 338i
The Vendor ID assigned by Leuze electronic for the BCL 338i is 121h = 289d.
Detailed information on the device description file and the object directory can be
found in Chapter 10.
3.4.2 Device profile
The object designations and groupings of the generic device profile of the BCL 338i are
based on common bar code reader profiles.
Detailed information can be found in Chapter 11.4.
3.4.3 Starting the BCL 338i in the EtherCAT system
As is common for EtherCAT, the BCL 338i runs through different states when starting up:
"INIT", "PREOP", "SAFEOP" and "OPERATIONAL".
Detailed information can be found in Chapter 11.
22 BCL 338i Leuze electronic
3.5 Further settings
Note!
With the BCL 338i, the configuration of the device functionality is generally performed via
the webConfig tool (see Chapter 9). EtherCAT is only used to set the bus-specific parameters for communication.
A special option for device configuration via EtherCAT is the transfer of "PT sequences". Information on this topic is only available on request.
After the basic configuration of the operating mode and the communication parameters, you
need to carry out further settings:
• Decoding and processing the read data
Define at least one code type with the desired settings.
• Via webConfig:
Configuration -> Decoder
• Control of the decoding
Configure the connected switching inputs according to your requirements. To do
this, first set the
• Via webConfig:
Configuration > Device > Switching inputs/outputs

If a display is available, the following information appears successively during startup:
• Startup
• Device designation e.g. BCL 338i SM 102 D
• Reading Result
If Reading Result is displayed, the device is ready.
Operation of BCL 338i
After voltage (18 … 30VDC) has been connected to the switching input, a read process is
activated. In the standard setting, all common code types for decoding are released; only
the 2/5 Interleaved code type is limited to 10 digits of code content.
If a code is moved through the reading field, the code content is decoded and forwarded to
the superior system (controller) via EtherCAT.

3.7 Bar code reading
To test, you can use the following bar code in the 2/5 Interleaved format. The bar code
module here is 0.5:
Modul 0,5
6677889900
Provided your BCL 338i model has a display, the read information appears on this display.
The PWR LED goes off briefly and then turns green again. Simultaneously, the read information is forwarded to the superior system (PLC/PC) via the Ethernet.
Please check the incoming data of the bar code information there.
Alternatively, you can use a switching input for read activation (switching signal of a photo-
electric sensor or 24VDC switching signal).

4.1 About the bar code readers of the BCL 300i series
Bar code readers of the BCL 300i series are high-speed scanners with integrated decoder
for all commonly used bar codes, e.g. 2/5 Interleaved, Code 39, Code 128, EAN 8/13 etc.,
as well as codes from the GS1 DataBar family.
Bar code readers of the BCL 300i series are available in various optics models as well as

reading tasks. Due to the large reading distance combined with the great depth of field, a
large opening angle and a very compact construction, the device is ideally suited for the
conveyor and storage technology market.
The interfaces (RS 232, RS 485 and RS 422) integrated in the various device models and
the fieldbus systems (PROFIBUS DP, PROFINET-IO, Ethernet TCP/IP UDP, EtherNet/IP
and EtherCAT) offer optimum connection to the superior host system.

General information
The integrated fieldbus connectivity = i contained in the bar code readers of the BCL 300i
series facilitates the use of identification systems which function without connection unit or
gateways. The integrated fieldbus interface considerably simplifies handling. The Plug-andPlay concept enables easy networking and very simple commissioning: Directly connect the
respective fieldbus and all configuration is performed with no additional software.
For decoding bar codes, the bar code readers of the BCL 300i series make available the
proven CRT decoder with code reconstruction technology:
The proven code reconstruction technology (CRT) enables bar code readers of the
BCL 300i series to read bar codes with a small bar height, as well as bar codes with a
damaged or soiled print image.
