2.1 Safety Standards
The barcode reader BCL 34, the modular hoods with integrated connectors MS 34 103/
MS 34 105, and the optional modular service display MSD 1 101 have been developed,
produced and tested subject to the applicable safety standards. They correspond to the
state of the art.
2.2 Intended Use
Attention!
The protection of personnel and the device cannot be guaranteed if the device is operated
in a manner not corresponding to its intended use.
Barcode readers of the type BCL 34 are conceived as stationary, high-speed scanners with
integrated decoders for all current barcodes used for automatic object recognition.

easy connection of barcode readers of type BCL 34 in a Profibus system and for the setting
of the respective Profibus address (see chapter 6.3 "Address setting").
The modular service display MSD 1 101, which is optionally available, displays operational
data of the BCL 34 and is used as a simple means of access to the service interface.
In particular, unauthorised uses include:
• rooms with explosive atmospheres
• operation for medical purposes
Areas of application
The barcode readerBCL 34 hasbeendevelopedin particular for the following areas of appli-
cation:
• labelling and packaging machines
• space-critical barcode reading tasks
• storage and conveying engineering, in particular for object identification on fast-mov-
ing conveyor belts

2.3 Working Safely
Attention!
Access to or changes on the device, except where expressly described in this operating
manual, is not authorised.
Safety regulations
Observe the locally applicable legal regulations and the rules of the employer's liability insur-
ance association.
Qualified personnel
Mounting, commissioning and maintenance of the device must only be carried out by qual-
ified personnel.
Electrical work must be carried out by a certified electrician.
Attention Laser Radiation!
WARNING: The barcode reader BCL 34 operates with a red light laser of class 2 acc.
to EN 60825-1 (2003/10). If you look into the beam path over a longer time period, the
retina of your eye may be damaged!
Never look directly into the beam path!
Do not point the laser beam of the BCL 34 at persons!
When mounting and aligning the BCL 34 take care to avoid reflections of the laser
beam off reflective surfaces!
Heed the laser safety regulations according to DIN EN 60825-1 in their most current
version! The output power of the laser beam at the reading window is at most 1.8mW
acc. to (DIN) EN 60825-1 (2003/10).
The BCL 34 uses a laser diode with low power in the visible red light range with an
emitted wavelength of 650 … 690nm.
CAUTION - the use of operating and adjusting devices other than those specified here
or carrying out of differing procedures may lead to dangerous exposure to radiation!

3 Description
BCL 34 device construction
Figure 3.1: BCL 34 device construction
3.1 The Barcode Readers BCL 34
The barcode readers BCL 34 are high-speed scanners with integrated decoder for all
barcodes 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. Further-
more, device variants with integrated heating are available.
Information on technical data and characteristics can be found in chapter 4.
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.

Leuze electronic BCL 34 11
TNT 35/7-24V
3.2 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 (DP IN)
•ProfibusOut(DPOUT)
• voltage supply (PWR IN)
MS 34 105
In addition, the MS 34 105 offers the following interfaces:
• for the modular service display (MSD)
• switching inputs and outputs (SW IN/OUT)
Please refer to chapter 5 for further information regarding the modular hoods with integrated
connectors.
3.3 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 inter-
face of the BCL 34 is tapped in this case and is made available at the 9-pin sub D connector
of the MSD (for further information see page 24). .
To connect to the MS 34 105, an 8-pin cable (M12) with a length of 2m is used (see
chapter 5 "Accessories / Order Designation").
Using the maintenance display, new settings for the BCL can be tried quickly and easily,
without having to project these settings via the Profibus. Once the optimal settings have
been found, which are to be adopted for the standard operation, these must be included in
the project in order for them to become permanently active.
Notice!
With very few exceptions, the BCL 34 is parameterised 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 ex-
plicitly 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 mem-
ories in the MS 34. They are, thus, safely stored even if a BCL 34 is replaced.

4.3 Device Construction and Components
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 Profibus IN and one Profibus 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.

4.4 Optical Data
Notice!
Please note that the size of the barcode module influences the maximum reading distance
and the width of the reading field. Therefore, when selecting a mounting location and/or the
barcode label, take into account the different reading characteristics of the scanner with var-
ious barcode modules.
For different reading tasks, the BCL 34 is available in various versions, both as a raster
scanner and as a single line scanner. Please refer to the following table or the respective
scanning curves for ratings.

4.4.3 Optics variants and reading fields
The BCL 34 is available with different optics. The optics differ in range and resolution (see
chapter 4.4.1).
• M optics: for small to medium modules
• F optics: for medium to large modules
• L optics: for medium to large modules
• J Optics: for ink-jet applications or if the barcodes are of low contrast or have gaps.
The following graphics display the ranges of the various BCL models.
Notice!
Please notice that the real scanning curves are also influenced by factors such as labelling
material, printing quality, scanning angle, printing contrast etc., and may thus deviate from
the scanning curves specified here.
The reading curves specified here were determined under the following conditions:
code type 2/5 interleaved, ratio = 1:2.5, label class A.
