BCL 34 device construction
Figure 4.1: BCL 34 device construction
The bar code readers BCL 34 are high-speed scanners with integrated decoder for all bar
codes currently in use, e.g. 2/5 Interleaved, EAN etc.
The many possible configurations of the device via PROFIBUS modules permit its adaptation to a multitude of reading tasks. Due to the small dimensions of the unit and the short
minimum reading distance, the BCL 34 may also be used in highly constrained spaces.
A special barcode reader with optics version J is available for all ink jet applications. This
reader has been optimised for low contrast barcodes that generally feature gaps. Furthermore, device variants with integrated heating are available.
Information on technical data and characteristics can be found in chapter 5.
TNT 35/7-24V
AutoReflAct
AutoReflAct stands for Automatic Reflector Activation and permits an activation without
additional sensors. This is achieved by directing the scanner with reduced scanning beam
towards a reflector mounted behind the conveyor path. As long as the scanner is targeted
at the reflector, the read gate remains closed. If, however, the reflector is blocked by an
object such as a container with a barcode label, the scanner activates the read procedure,
and the label on the container is read. When the path from the scanner to the reflector has
cleared, the read procedure has completed and the scanning beam is reduced and again
directed onto the reflector. The reading gate is closed.

Description
4.2 Modular hoods with integrated connectors MS 34 103/MS 34 105
The modular hoods with integrated connectors are necessary accessories for connecting
a BCL 34 in a PROFIBUS system. They are used to feed through the PROFIBUS connections, set the PROFIBUS address, and supply voltage to the BCL 34.
MS 34 103
The MS 34 103 offers the following interfaces:
• PROFIBUS In (HOST/BUS IN)
•PROFIBUS Out (BUS OUT)
• Voltage supply (PWR) and 1 switching input and output each (SW IN/OUT)
Figure 4.2: MS 34 103
MS 34 105
In addition, the MS 34 105 offers the following interfaces:
• Service interface (SERVICE)
• 1 further switching input and output each (SW IN/OUT)
Figure 4.3: MS 34 103
Further information on the modular hoods with integrated connectors may be found in the
following chapters.
14 BCL 34 Leuze electronic
4.3 Modular Service Display MSD 1 101
The modular service display is used to display the reading and operational data on the one
hand, and as simple access to the service interface on the other. The RS 232 service interface of the BCL 34is tapped in this case and is made available at the 9-pin sub D connector
of the MSD (for further information see page 30).
Figure 4.4: MSD 1 101
To connect to the MS 34 105, an 8-pin cable (M12) with a length of 2 m is used (see
chapter 6 "Accessories / Order Designation").
The MSD can be operated in different display modes which are stored in the parameter set
of the BCL. The required parameter for setting up the display mode can be altered via the
service interface. The LCD display contains two lines with 16 characters each. There are
3 display modes:
1. Single line:
a result is output in one line. If the information is longer than 16 characters, the characters > 16 are cut off. This means that two results may be output on the LCD display.
2. Double line:
a result is displayed over both lines. Thus, only one result is visible in the display.
3. Depending on the size:
if a result is > 16 characters, both lines are used
if a result is < 16 characters, one line is used and two results are displayed

Description
The input can be specified as a PT commentary or in the BCL Config parameter list, e.g.,
PT0001610x.
Using the maintenance display, new settings for the BCL can be tried quickly and easily,
without having to project these settings via the PROFIBUS. If these settings are to be
accepted for standard operation, these must be configured via PLC.
Notice!
With very few exceptions, the BCL 34 is configured via the PROFIBUS connection
group.Parameters which were set via the service interface are, therefore, overwritten in
PROFIBUS operation by the parameters stored in the project. If parameters in the project
were not explicitly changed, the corresponding default parameters are transferred.
In the BCLConfig configuration software, the parameter input fields which can be overwritten by the PROFIBUS are displayed with a blue background. Parameter input fields which
are not overwritten by the PROFIBUS are displayed with a white background.
If these parameters were changed, they are stored in one of the available parameter memories in the MS 34. They are, thus, safely stored even if a BCL 34 is replaced.

A modular hood of type MS 34 103 or MS 34 105 with integrated connectors is part of
every BCL 34. The two hoods with integrated connectors are used to connect the BCL 34
to the PROFIBUS. For this, they feature one HOST/BUS IN and BUS OUT connection each,
as well as an internal switch for address setting.
If only the connection to the PROFIBUS is intended, type MS 34 103 is sufficient.
If, in addition, switching input and output or a modular service display are to be connected,
an MS 34 105 is required. Although switching inputs and outputs are available on the
voltage supply connector, the switching inputs of the MS 34 105 have the advantage that
a standard sensor connector can be used.

5.5 Automatic reflector activation "AutoReflAct"
The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism. This is achieved by
directing the scanner with reduced scanning beam towards a reflector mounted behind the
conveyor path.
As long as the scanner is targeted at the reflector, the read gate remains closed. If,
however, the reflector is blocked by an object such as a container with a bar code label,
the scanner activates the read procedure, and the label on the container is read. When the
path from the scanner to the reflector has cleared, the read procedure has completed and
the scanning beam is reduced and again directed onto the reflector. The reading gate is
closed.

Notice!
autoReflAct does not function if the bar codes which are to be read are put on reflecting
surfaces, e.g. foils.

Reflector
Our recommendation:
• Use BCL 34 R1x100
• AutoRefl mode with or without reading gate control (single)
The maximum distances between the reflector and the BCL depend on the reflector used.
A summary is provided in the following table. The fundamental arrangement of reflector and
BCL is shown in figure 5.12.
