BCL 21/22 device construction
The Bar Code Readers BCL 21/22
The many possible configurations allow the adaptation of the device to a multitude of reading
tasks. Due to the small dimensions, the BCL 21/22 may also be used in highly constrained
spaces. The low weight permits the installation into machines that were not designed for
heavy components. The various beam exits (perpendicular/front side) extend the area of
application of the BCL 21/22 and help it to adapt.
The connector units MA 2/MA 4… offer simple electrical installation in conjunction with the
BCL 21. Information on technical data and characteristics can be found in chapter 4.
BCL 22 "stand alone"
The bar code reader BCL 22 is operated as a "stand-alone" device. The BCL features a
cable for the electrical connection of the supply voltage, the interface, and the switching
inputs.
BCL 21 with MA 2
If several BCLs are to be networked, the use of a connector unit MA 2/MA 4… is recommended for each BCL 21. Electrical connection, commissioning, and service can be
comfortably carried out in a short period of time. BCL 21 and MA 2/MA 4… are arranged
separately. The two devices are connected by a cable.

The bar code readers BCL 21/22 are high-speed scanners with integrated decoder for all
bar codes currently in use, e.g. 2/5 Interleaved, EAN etc.

Description
3.1.1
Networking
Up to 30 scanners can be networked via the connector unit MA 2 and a bus master MA 30/
31. For this, every BCL 21 is assigned its own hardware address in the corresponding MA 2.
The devices are networked by connecting the individual RS 485 interfaces in parallel.
multiNet plus
In the Leuze multiNet plus, the individual network devices sequentially transfer their data to
the network master MA 30/31 when requested. In addition, every bus node declared a slave
receives a device address which is adjusted in the corresponding MA 2/MA 4… via a coding
switch. The device address remains in the MA 2/MA 4… when the scanner is replaced.
The master then transmits the data of all network devices via its host interface to a primary
PLC control system or a computer, i.e. it "collects" the scanner data in the network and transmits them to an interface on the host computer. This reduces interface costs (CPs) and time
spent programming the software.

Description
Two-wire RS 485
The Leuze multiNet plus is optimised for fast transmission of scanner data to a primary host
computer. The multiNet plus consists physically of a two-wire RS 485 interface through
which the multiNet plus software protocol is controlled. This makes wiring the network easy
and inexpensive as slaves are connected to one another in parallel.
Interface modules
TNT 35/7-24V
Shielded, twisted pair conductors should be used for the multiNet. This allows a total
network length of up to 1200 m. Connection of the network to the primary computer is made
via the host interface of the MA 30/31 which can be equipped with 4 different physical interface modules. The available options are modules for RS 422, RS 232, TTY or RS 485.

Overview of the BCL 22 types
Optics variants and reading fields
The BCL 21/22 is available with three different optics. The optics differ in range and resolution (see see chapter 4.1 "General Specifications BCL 21/22").
• N optics: for small modules.
• M optics: for small to medium modules
• F optics: for medium to large modules
The following graphics display the ranges of the various BCL models.
Notice!

Device Arrangement
Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• size, orientation, and position tolerance of the barcodes on the objects to be scanned
• the reading field of the BCL 21/22 in relation to the bar code module width
• the resulting minimum and maximum reading distance from the respective reading
field
For specific information, please refer to chapter 4.4.
Notice!
The best reading results are obtained when
• the bar code is moved along the reading window at an angle of approx. 9 … 15°.
• the reading distance lies in the middle area of the reading field.
• you do not use high-gloss labels.
TNT 35/7-24V
Application examples

Applications with perpendicular and front side beam exit
Mounting location
! When selecting a mounting location, pay attention to
• maintaining the required environmental conditions (temperature, humidity)
• possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
• lowest possible chance of damage to the scanner by mechanical collision or jammed
parts.

Connection
Attention!
Do not open the device yourself under any circumstances! There is otherwise a risk of uncontrolled emission of laser radiation from the device. The housing of the BCL 21/22 contains no parts that need to be adjusted or maintained by the user.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the nameplate.
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BCL 21/22 and the
MA 2/MA 4… must have a secure electrical insulation through double insulation and safety
transformers according to EN 60742/IEC 60742 (functional low voltage).
Be sure that the earthing conductor is connected correctly. Error-free operation is only guaranteed when the device is properly earthed.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.

Setting the device address
The device address is set in the MA 2/MA 4… using a rotary code switch. The setting is
carried out as follows:
! Set the device address to
• 0, if the combined BCL 21 / MA 2/MA 4… unit will not be operated in a network,
• 1…30, if several BCL 21 / MA 2/MA 4… units will be operated in a network. Each
multiNet plus network device must have a different device address assigned to it. If
the MA 2/MA 4… is connected to the multiNet Master, the device combination BCL 21
with MA 2/MA 4… automatically turns into a multiNet plus slave device.
Notice!
Address 31 is used for resetting the parameters.

Notice!
From the hardware address, the BCL 21 detects that networking is required. With the
BCL 21/22, it is possible to perform a reset using the software and the online commands. In
addition, it is possible to perform a reset by switching off the supply voltage. The parameters
are not lost as a result of the reset. For information on the reset commands, see chapter 9.
The LED remains dark during a reset; the green LED illuminates when the device is ready
for operation.
7.2
Function Test
"Power On" test
After connecting the operating voltage, the devices carry out an automatic "Power On" function test. The LED on the front side of the MA 2/MA 4… lights up. In the case of factory
settings, the green LED flashes. In the additional service mode, the orange LED lights up.
Interface
Proper function of the interface can be tested easiest in service operation using the service
interface with the "BCLConfig" programming software and a notebook computer. For order
numbers, see chapter 5.
"Online commands"
Using the "Online" commands, important device functions can be checked, e.g. proper functioning of the laser.
Problems
Should problems occur during device commissioning, refer first to chapter 8.2. Should a
problem persist after checking all electrical connections and settings on the devices and
host, please contact a Leuze service office near you (see the back page of this operating
manual).

Commissioning
Setting the Parameters
In the device combination BCL 21/22 with MA 2/MA 4…, two different parameter sets are
managed:
• factory default parameter set
• current parameter set
Before a parameter set is loaded into the BCL 21/22 processor memory, the validity of the
parameter set is checked using checksums.
Factory default parameter set
This parameter set contains the default settings made ex works for all BCL 21/22 parameters. It is permanently stored in the ROM of the BCL 21/22. The parameter set with the
default settings is loaded into the memory of the BCL 21/22,
• the first time the device is commissioned after delivery
• following the command "Factory Default" in the parameterisation program
• if the checksums of the current parameter set are invalid.
Current parameter set
In this parameter set, the current settings for all device parameters are stored. When the
BCL 21/22 is in operation, the parameter set is stored in the EEPROM of the BCL 21/22. The
current set can be stored:
• by copying a valid parameter set from the host computer
• by means of an off-line setup with the PC setup program BCLConfig
The current parameter set is loaded into the memory of the BCL 21/22,
7.3.1
Service Operating Mode
Setting the required parameters is carried out easiest in the 'Service' operating mode.
Service interface
By switching the operating mode switch in the MA 2/MA 4… from operation (switch in upper
pos.) to service (switch in lower pos.), the connection to the host computer is interrupted and
the RS 232 interface is activated. At the BCL 22, the interface is activated via a bridge
between the pins 7 and 15 on the 15-pin sub-D connector.
The connector unit MA 2/MA 4… offers a service interface for commissioning the reading
stations in a network. This interface can be accessed by removing the housing cover. It has
a 9-pin Sub-D connector (see figure 7.1).

Display Elements
A LED labelled "SWO" is located on top of the MA 2/MA 4…. It indicates the state of the
switching output 1. On the BCL 21/22, you can find three LEDs that indicate different states.
For detailed information regarding the state displays of the LEDs please refer to chapter 4.2.
8.2
Error Handling
Errors are indicated on the BCL 21/22 via the ERR LED. Additional error, warning and status
messages are transmitted via the Host interface.
Types of errors
Errors are divided up into the following types:
• Warnings
• Serious errors
Warnings
Warnings indicate temporary operating faults which do not affect the proper functioning of
the device.
Serious errors impair the proper functioning of the device. The device must be reinitialised.
Troubleshooting
Isolated warnings can be ignored, since the BCL 21/22 will continue to function properly.
Following a serious error, you should re-initialise the BCL 21/22. It will then usually again
function properly. If a hardware problem is present, the BCL 21/22 will not reinitialise.
Warnings and errors which occur frequently can be corrected easiest using the BCLConfig
software.
If you cannot correct faults and errors with the software, please contact a Leuze electronic
sales office or service facility. For addresses, please refer to the back page of this operating

Quiet zone: the area to the left and right of the bar code
Module:
width of the narrowest line in the bar code
According to the code specifications, each bar code must have a quiet
zone which is 10 times as wide as the module of the bar code.
Ex: for a code having a module of 0.5mm, 5mm blank space must be
present at both the left and right of the code.
By default, the scanner checks a quiet zone which is 7 times greater
than the module. This means that 7 times or greater is o.k.

Alignment mode
Command
’JP’
Description
This command is used for the easy mounting and alignment of the
BCL 21/22. After the function has been activated by ’JP+’, the scanner
continuously supplies status information via the serial interfaces.
With this online command, the scanner is set to terminate the decoding
after 100 successfully decoded labels and output the status information.
Subsequently, the read process is reactivated automatically.
As status, the output returns the following values:
• scans which contain the valid label information on the basis of
100 scans,
• the decoding result.
These values can be used to determine the decoding quality.
In addition to the output of the status information, the laser beam is used
to display the reading quality. Depending on how many labels were able
be extracted, the duration of the laser's "off" time increases.
If the reading quality is high, the laser beam flashes in brief, regular intervals. The worse the decoder decodes, the longer the pauses become during which the laser is switched off. The flashing intervals become more
and more irregular because the laser may, in total, be active for longer to
extract more labels. The duration of the pauses has been stepped in such
a way that they can be distinguished by the eye.
