Device Description
1.1
The Function of the Device
The BCL detects bar codes using a folded scan line (producing a cross) and decodes them.
The BCL transmits the data via the serial host interface to a host/PC for further processing.
Figure 1.1 gives on overview of the BCL’s functions

The BCL offers two decoders:
• the CRT decoder for decoding bar codes with small code heights, of bar codes with
damaged or dirty print and for reading extremely tilted bar codes (azimuth angle)
• the tried-and-tested standard decoder of the BCL series
The BCL derives from the read processes useful diagnosis data which can be transferred to
the host, and also contains operation data that can be called up. The read quality can be
checked in the operating mode percentage evaluation.
The BCL needs a suitable trigger to start a read process as soon as an object is in the
reading field. A time window ("scan gate time") for the read process is then opened in the
BCL. In the basic setting, triggering takes place through an external reading cycle sensor.
Alternatively, free-oscillating operation or a command via the host interface can also serve
as triggers.
Four LED status indicators provide optical information on the current operation status.
In the case of external triggering by a sensor, the switching input "SE 1" tells the BCL when
to start the read process. As an alternative to the auto-focus function, the five switching
inputs "SE 2 … SE 6" switch the focus position in response to events (event-driven). The
inputs "SE 5" and "SE 6" can also be assigned special functions. The four switching outputs

Device Description
"SWO 1 … SWO 4" can be assigned various output functions for result status and actuate
external devices, e.g. a PLC.
The BCL is operated and configured on the user interface of the PC software BCL-Config
through the terminal interface (auxiliary interface) or using command strings through the
host interface/service interface.
System, warning and error messages provide assistance in set-up/troubleshooting during
commissioning and read operation.
1.2
Scope of Delivery
The following items are included in the BCL device package:
• an information sheet (device information) with electrical connection diagram and
quick-start
• an extra set of laser warning signs (self-adhesive) of Class 2 in German/American
English and French/American English
depending on the number of devices ordered one set of technical documentation in one
or several copies, comprised of:
• the BCL 90 operating manual (in German or English)
• one set of DOS-formatted diskettes (3.5 inch) with the PC software BCL-Config for
Windows.
Chapter 3, on page 19 gives an overview of available accessories for the device, electrical
connections and mounting as well as connection modules and cables.

Mounting
Selecting the Mounting Site
In selecting the mounting site, the distance between the BCL and host as well as the
distance between the BCL and the bar code have to be taken into consideration.
Distance between the BCL and host
If it is not connected to the Leuze network or a bus connection, the BCL can be mounted at
a distance of max. 1200 m from the host. The actual distance, however, depends on the
selected physical type of the host interface and the adjusted data transmission rate.
Distance between the BCL and MA 90
The MA 90 should not be mounted further than 10 m away from the BCL because the PC
accesses the terminal interface of the BCL through the software BCL-Config via the module
(RS 232 type).
4.2.6
Mounting Accessories
The BCL is attached by way of two fastening threads (M6) located above the electrical
connections. Figure 4.2 shows the location of the threads.
The dimensions of the BCL housing are given in Figure 2.1.

Mounting
The mounting supports are designed in such a way that allows diverse mounting variations
and the orientation of the BCL on two levels. Figure 4.3 shows two examples for mounting
the device.
Figure 4.3: Mounting options for BCL 90 CAX … with mounting bracket BT 90 X
The dimensions of the mounting supports are given in Section 3.3, on page 20.
4.2.7
Distance Between BCL and Bar Code
Principle Orientation of the Scan Line to the Bar Code
The BCL is used for reading omni-directional bar codes on the sides or on the top of objects.
Figure 4.4 shows the basic arrangement of the BCL.
Read Distance to Bar Code
The distance between the reading window of the BCL and the bar code may not exceed the
technical limits specified for the device. The height of the reading field in relation to the read
distance is given for various resolutions (module widths) in Chapter 2.3.3 "Reading performance data for compact OMNI bar code scanner".
Figure 4.4 defines the read distance a from the reading window.

BCL 90 CAX

Leuze electronic
Mounting
Owing to the X principle used for beam deflection, the reading field height (length of the scan
line) depends on the read distance.
Angular alignment of BCL
All read angles that are possible between the scan line and bar code must be taken account
(Figure 4.5 and Table 4.1).

b: Inclination angle (pitch)
g: Rotation angle (skew)

Counting Direction for Code Position CP
The BCL can scan and decode several bar codes in every reading operation.
In this process, it determines for each bar code its read diagnosis data relating to its location:
• the position (CP value) of the bar code middle within the scan line
Figure 4.6 shows the counting direction for the code position. The cross in the reading
window below the yellow laser warning sign indicates the counting direction for the code
position.
Determination of the code position makes it possible to separate identical bar codes (code
type, code length and data content all identical) and to assign the location of the bar code
data in the reading result to its position on the object.

Operation
5.1
Overview of Commissioning Steps
• Commissioning the BCL with basic factory settings (quick-start).
In this configuration, the BCL can be operated without connecting it to a PC.
• Configuring (parameterising) the BCL for use with BCL-Config or command strings
(see Technical Description BCL 90, page 102)
5.2
Basic settings
Table 5.1 lists the basic factory settings of the BCL. The parameters of the basic settings are
selected in such a way that the BCL can be used in this configuration directly or only with
small adjustments in many applications. A PC is not needed for commissioning with the
basic settings
The basic setting values are permanently stored both in the BCL (ROM) and in the database
of BCL-Setup. They can be downloaded any time in the operating memory (RAM) of the BCL
or displayed in the tabs of BCL-Config.

Maintenance
6.1
Servicing during Operation
In order to maintain its full reading capability, the BCL needs a clean reading window.
We therefore recommend checking regularly whether the reading window is dirty, particularly in rough operating environment (dust, abraded particles, humidity, finger prints).
Damage to the eyes through laser radiation!
The BCL operates with a red light laser of Class 2. Staring at the laser beam may
cause damage to the retina.
• Never look at the laser beam directly (same as sunlight).
• Turn off device during cleaning
Avoid looking at the reading window at all times during device operation
Damage to the reading window!
The reading window is made of glass. The reading capacity is reduced through scratches
and streaks on the reading window.
• Use mild detergents without powder additives
• Avoid scratching and scrubbing motions on the reading window
• Clean the reading window in regular intervals with a mild detergent without powder
additives, e.g. an antistatic window cleaning detergent. Figure 6.1 shows the areas to
be cleaned.
Use a soft, lintfree cleaning cloth.

Maintenance
Clean here:
Figure 6.1: Cleaning the reading window
• Also clean the LED indicator at the back of the device as required.
Clean other, optically relevant surfaces:
• Also clean the optical surfaces of sensors (e.g. retro-reflective photo electric sensors)
for external reading cycle generation and/or object height detection (Figure 6.2). Fouling may cause erroneous switching.

Maintenance
Maintenance
The BCL runs without maintenance. Its self-monitoring functions provide for a long operation
free of failures.
The BCL outputs device and functional disorders in the form of messages via the service
interfaces. These can be displayed on the PC screen in the extended mode of the terminal
emulator of the user interface of BCL-Config.
