2.3 Working safely
Attention Laser Radiation!
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 at
persons! When mounting and aligning, avoid reflections of the laser beam off reflec-
tive surfaces!
Adhere to the applicable legal and local regulations regarding protection from laser
beams acc. to IEC 60825 in its latest version.
The scanner window is the only aperture through which light may be observed on this
product. The device must not be tampered with and must not be changed in any way!
There are no user-serviceable parts inside the device.
A failure of the scanner motor while the laser diode continues to emit a laser beam
may cause the emission level limit to be exceeded. The device has safeguards to pre-
vent this occurrence. If, however, a stationary beam is emitted, the failing barcode
reader should be disconnected from its power source immediately.
The BCL 8 uses a laser diode with low power in the visible red light range with an
emitted wavelength of approx. 650nm. The output power of the laser beam at the
reading window is at most 1.3mW acc. to EN 60825-1.The average laser power is less
than 1mW in accordance with laser class 2 acc. to EN 60825-1 and
U.S. 21 CFR 1050.10 with Laser Notice No. 50.
CAUTION: Use of controls or adjustments or performance of procedures other than
specified herein may result in hazardous light exposure! The use of optical instru-
ments with the product will increase eye hazard!
Notice!
It is important that you attach the sticky labels supplied to the device (notice signs and laser
emissionsymbol)!Ifthesignswould be covered due to theinstallationsituationoftheBCL 8,
attach them close to the BCL 8 in such a way that reading the notices does not necessitate
looking into the laser beam!

Device construction of the BCL 8
Figure 3.1: Device construction of the BCL 8
3.1 The BCL 8 barcode reader
The BCL 8 barcode reader is a laser scanner with integrated decoder for all commonly used
barcodes, e.g. 2/5 Interleaved, Code 39, Code 128, EAN etc., with an extremely small
housing.
The many possible configurations of the device allow it to be adapted to a multitude of
reading tasks. Due to the small dimensions of the unit and its wide reading field, the BCL 8
may also be used in highly constrained spaces.
Information on technical data and characteristics can be found in chapter 4.

3.2 Stand alone operation
The BCL 8 barcode reader is operated as a "stand-alone" device. It is equipped with a five-
core cable with open ends or a 5-pin M12 connector for the electrical connection of the
supply voltage, the interface and the switching input.
With MA 8.1 connector unit
TheMA 8.1connectorunit simplifies theelectricalinstallationof the barcodereaderin stand-
alone operation with an RS 232 interface.
For details on the connector units, see chapter 5.
With MA 8-01 connector unit
The MA 8-01 connector unit simplifies the electrical installation of the barcode reader in
stand-alone operation with an RS 485 interface.
For details on the connector units, see chapter 5.
3.3 Daisy chain network
A daisy chain is a network based on the RS 232 interface. All devices, which consist of a
transmitter and a receiver, are connected to one another to form a ring. The transmitter of
one device is directly connected to the receiver of the next device until all devices are
connected together to form a ring. One device performs the task of the host system.
Ideally, all BCL 8 devices are to be connected to one another with MA 8.1 connector units
so that:
• the voltage supply of the BCL 8/MA 8.1 is ensured.
• TxD to RxD of the RS 232 is established from one BCL 8 to the next (host).
• the switching outputs and inputs are connected (optional).
A maximum of seven BCL 8 devices may be operated in the daisy chain together with one
host. Further information is available from your Leuze sales office.

Notice!
Please note that the size of the barcode module influences the maximum read distance and
the width of the reading field. Therefore, when selecting a mounting location and/or the bar-
code label, take into account the different reading characteristics of the scanner with various
barcode modules.
For different reading task and connection requirements, the BCL 8 is available in various
models (see chapter 4.4.1 "Type overview").

4.4.2 Reading fields
Notice!
Please note that the actual reading fields are also influenced by factors such as labelling ma-
terial, printing quality, scanning angle, printing contrast etc., and may thus deviate from the
reading fields specified here. The origin of the read distance always refers to the front edge
of the housing of the beam exit.
