Operating Instructions
Installation procedure (overview)
Reading pulses via switching input "Sensor" (default setting)
1. Check the delivery to make sure that none of the components is missing.
2. Mount the CLX at the reading station and align it with the object carrying the bar code.
3. Mount the AMV/S60 Connection Module.
4. Connect the CLX to the AMV/S60 Connection Module using the two cables
no. 2020302. Alternatively, connect the device to the AMV/S60 via the external
parameter memory no. 2020307.
5. Connect the reading pulse sensor to the "Sensor" switching input in the AMV/S60.
6. Connect the host to the host interface in the AMV/S60.
Adapt the AMV/S60 to the host interface type of the CLX.
7. Switch on the power supply to the AMV/S60.
The "Device Ready" LED lights up after the CLX has started.
CLX with external parameter memory (in connector cover) connected:
After the CLX has started, it copies the internal parameter set to the external parameter
memory if the memory is empty. Then the "Read Result" LED lights up.
8. Switch on your PC and start Windows
9. Install the "CLV-Setup" software and online CLV-Setup Help from the CD-ROM ("Manuals & Software") on your PC.
10. Connect the PC to the auxiliary interface of the CLX. To do so, connect the 3-core
RS 232 data cable (null modem cable) (e. g. no. 2014054) to the "Service plug" in the
AMV/S60.
11. Start the "CLV-Setup" program.
CLV-Setup establishes communication with the CLX and uploads the parameter set.
The parameters are then displayed on the tabs.
12. Carry out a test read using test bar codes (trigger the CLX accordingly).
Display the reading result in the Terminal Emulator window of the "CLV-Setup" program.
13. Configure the CLX for the application using the settings on the tabs in CLV-Setup. Copy
(download) the modified parameter set to the CLX temporarily.
Do not switch off the power to the AMV/S60 (CLX)!
14. Test the application under realistic conditions.
15. Check whether the data is transmitted correctly between the CLX and host.
16. If necessary, correct and optimize the parameter values.
Copy (download) the parameter set permanently to the CLX.
CLX with external parameter memory (in connector cover) connected:
Copy the modified parameter set to the external parameter memory when CLV-Setup
asks you for confirmation.
17. Save the parameter set as a configuration file "*.scl" in the "CLV-Setup" program.
TM
(minimum requirement: Windows 95TM).
The CLX can then be operated with the application-specific settings.

Chapter 2 Operating Instructions
Safety information
CLX490 Compact OMNI Scanner
2.3 General safety instructions and protection measures
¾ Always read the general safety instructions carefully and observe them at all times.
Please also observe the warnings in front of the operating instructions in each chapter
of this document.
Shock hazard!
Depending on the type of device, the AMS60 Connection Module (accessory) for the CLX is
connected to a mains voltage of 230 V AC 50 Hz or 115 V AC 50 to 60 Hz.
¾ When working with electrical equipment, always follow the relevant safety specifications.
Laser beam can cause blindness!
The CLX uses a class 2 red-light laser. Looking directly at the laser beam can seriously
damage your eyesight.
The entire glass window acts as a laser outlet aperture.
Caution – use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
¾ As with sunlight, never look directly into the laser beam.
¾ Do not direct the laser beam at the eyes of other persons.
¾ Mount and align the CLX490 in such a way to prevent the laser beam reflecting off
mirrored surfaces.
¾ Do not open the housing.
(Opening the housing does not deactivate the laser diode).
¾ Observe the laser protection specifications (latest version).
Laser power
The laser operates at a wave length of λ = 650 nm (visible red light). The power output at
the reading window is max. 2.8 mW.
The emitted radiation is not dangerous to human skin.
The product is classified in laser class 2 (laser class II) in accordance with EN 60825-1,
IEC 60825-1, and 21 CFR 1040.10 (for publication date, see the warning sign on the device).
Note No maintenance required to keep this product in compliance with laser class II.
Laser warnings
The laser warning symbols (Fig. 2-1) can be found on the CLX at the following locations:
The laser warning symbol is positioned on the reading window. The GB/US laser warning is

Fig. 2-1: Laser warning labels on the CLX
Note A set of laser warnings in German/US English and French/US English is included in the de-
livery scope. The GB English/US English warnings can be pasted over with these if necessary.
If the CLX is installed in a machine/panel with the result that the laser warning labels
are no longer visible, additional warnings in the same language (not included in the
scope of delivery) must be provided on the machine beside the emergence aperture
of the laser beam.
Internal protective circuits
The CLX is equipped with monitoring circuits that deactivate the laser diode in the event of
a malfunction.
Activation and deactivation of the laser diode is controlled by the reading pulse trigger.
A timer (laser timeout) automatically deactivates the laser diode in Reading mode ("Sensor
input" and "Serial interface" trigger mode) if the reading interval has not ended after
10 minutes (default setting). However, it does not end the reading interval. In this case, the
CLX outputs the message
"Laser safety timeout"
on the auxiliary interface. The reading interval must be terminated by resetting the trigger
signal. The laser diode is activated again by the next reading trigger.
The laser timeout can be set in the range of 1 min to 25 h or deactivated (see Table 6-7,
Page 6-11).
In the "Percentage Evaluation" mode as well as in the pulse mode "Free-running", in
reading mode, the laser diode is constantly activated. In the pulse mode "Object Polling" the laser diode is activated due to the parameterized search/pause ratio.
Note In Reading mode, the CLX carries out a measurement referencing at regular intervals. During
referencing, it turns the laser diode on for a maximum of 10 seconds.

CLX490 Compact OMNI Scanner
3.2 Method of operation
The CLX first scans the bar code with a folded scan line (resulting in a cross) and then decodes it. The data is forwarded via the main data interface (serial host interface) to a host/
PC for further processing. An overview of the CLX functions is provided in Fig. 3-2.

The CLX is equipped with two decoders:
• The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding
bar codes with small code height, bar codes that are dirty or damaged, as well as bar
codes that are tilted excessively (azimuth angle)
• The tried-and-tested standard decoder of the CLV series
The CLX derives useful diagnosis data from the reading process and can transfer it also to
the host. It also records operating data that can be interrogated at any time. The quality of
the read can be checked in percentage evaluation mode.
To start the reading process when an object is located in the reading field, the CLX requires
a suitable trigger. This opens an internal time window ("reading interval") in the CLX. In the
default configuration, this trigger is supplied by an external reading pulse sensor. Alternative
trigger sources include free-running mode or a command via the host interface (for more
complex applications: OTC trigger).
With small object distances (object distance < reading gate length) the bar code has to be
allocated to the right object with the help of the internal tracking of the CLX.
The current operating status is indicated by four LEDs.
If the trigger is supplied externally, the "Sensor" switching input instructs the CLX to start the
reading process. The five "IN 0 to IN 4" switching inputs switch the focus position in
response to certain events, as an alternative to the autofocus function. The "IN 4” input can
also be assigned to special functions. The four "Result 1 to Result 4" switching outputs can
be assigned to different functions alternativly for displaying the result status and also control
external devices, such as a PLC.
The CLX is operated and configured via the auxiliary interface (serial auxiliary interface) using
the CLV-Setup software or via the host interface/auxiliary interface using command strings.
System, warning, and error messages help you configure the device and locate the source
of errors during startup and reading mode.

Product description
3.2.1 Autofocus function
The autofocus function enables the CLX to detect the distance of an object without the need
for external sensors, and then adjust the focus position automatically. In order to do so, the
CLX measures the object distance in its reading field in front of the reading window and internally creates a distance profile. Following this, it positions the focus on the object.
3 operating modes are provided for various applications:
• Minimum distance: the CLX focuses on the minimum distance in the distance profile
and ignores the background in the reading field. Application: with unobstructed view of
the object without any surrounding objects protruding into the reading plane.
One object with bar code(s) only is inside the reading field during one reading pulse.
• Differential background: the distance profile of the reading field background is pro-
grammed (teach-in) in the CLX without any objects present. The CLX focuses on the object which it recognizes by comparing the object with the background. Application: with
unobstructed view of the object restricted by other objects that protrude into the reading plane.
One object with barcode(s) only is inside the reading field during one reading pulse.
• Differential background and tracking: if several objects with different distances are
positioned in the reading field at the same time (distance conflict), the CLX focuses on
the object that is nearest to but has not exceed its internal focus switchover point.
Application: in OTS operation (applications with tracking by the OMNI Tracking Controller
OTC 400), or stand alone in internal tracking mode.
The distance profile of the background can also be displayed in the "CLV-Setup" program.
The reading field is defined by the autofocus range. The park setting of the focus position,
from which the device focuses for each read, can be specified in addition to a time and/or
position-related delay (timeout or hysteresis). If necessary, an offset can be defined for the
focus position to be set by the measurement. The depth of field, which radiates in the direction of the scan line and is caused by the V-principle of the beam deflection, is optimized as
a result (Fig. 3-3).

3.2.2 Event-controlled dynamic focus control
As an alternative to the autofocus function, the CLX can switch its focus position in response
to certain events and thus dynamically cover a large reading range. A maximum of eight
reading ranges can be defined as distance configurations for this purpose and approached
consecutively in reading mode (see Fig. 3-4).

Reading distance
The switch over takes place in response to changes in the object distance (with reads from
above: object height detection). The trigger source for the switchover is a signal combination
at the "IN 0 to IN 4" switching inputs, a command on the host interface/auxiliary interface
or the integrated timer (e. g. for search mode). The distance configurations are assigned to
the swichover sequence by means of a programmable assignment table. The object distance measurement of the autofocus function can additionally be used to define the distance configurations.
3.2.3 Additional components
Heater
The CLX can be permanently equipped with a heater for applications involving temperatures
up to max. –30 °C (e. g. in a freezer).
The design, technical data, and power-up behavior of the CLX are described in Chapter 10.4
Optional heating, Page 10-12.
External parameter memory
The external parameter memory is located in a connector cover which, when mounted,
covers the two electrical terminals on the CLX (IP 65). The parameter memory saves you
time when a CLX is replaced locally by providing a copy of the current parameter set. In other
words, you do not have to configure the new device.
For information on applications and operating procedures, see Chapter 10.3 Installing and
operating the external parameter memory, Page 10-8.

4.2.4 Replacing the laser warning label
If necessary, replace the GB English/US English laser warning label with the required language (Fig. 4-1).
The device is delivered with a set of laser warnings in:
• German/US English laser warning and
• French/US English laser warning
See also Chapter 2.3 General safety instructions and protection measures, Page 2-2.
Supplied laser warnings:
Fig. 4-1: Replacing the laser warning labels
4.2.5 Selecting the mounting location
When you select the mounting location, the distance between the CLX and the host and
between the CLX and the bar code are important.
Distance between the CLX and the host
The CLX can be mounted at a maximum distance of 1,200 m from the host without a
connection to the SICK network or a bus. In practice, however, the distance depends on the
physical configuration of the host interface and the data transfer rate (see Table 5-7,
Page 5-8).
Distance between the CLX and the AMV/S60 Connection Module
The AMV/S60 Connection Module should not be located further than 10 m from the CLX,
since the "CLV-Setup" program on the PC accesses the auxiliary interface (RS 232) of the
CLX via this module.
