Installation procedure (overview)
CLV in stand-alone configuration
Start/stop mode: Reading trigger via “Sensor“ switching input (default setting)
1. Check the delivery to make sure that none of the components is missing.
2. Mount the CLV at the reading station and align it with the object carrying the bar code.
3. Mount the CDB 420 or CDM 490 Connection Module.
4. Connect the CLV as followed:
CDB 420 Connection Module: using the cable no. 2 027 046. Alternatively, connect
the CLV using the external parameter memory no. 2 030 023.
CDM 490 Connection Module: using two cables no. 2 020 302. Alternatively, connect
the CLV using the external parameter memory no. 2 020 307.
5. Mount the sensor for starting/stopping the reading pulse.
6. Connect the reading pulse sensor to the "Sensor (1)" switching input in the CDB 420
or CDM 490.
7. Connect the host to the host interface in the CDB 420 or CDM 490.
8. Switch on the power supply to the CDB 420 or CDM 490.
The "Device Ready" LED lights up after the CLV has started.
CLV with external empty parameter memory connected (no. 2 020 307 or 2 030 023):
After the CLV has started, it copies the internal parameter set to the external parameter
memory if no CMC 400 parameter memory is available in the CDB 420/CDM 490.
Line scanner with oscillating mirror:
In the default setting, the CLV deflects the scan line around the position CW = 50 with
a frequency of 1 Hz and an oscillating amplitude of max. ±20°(±40 CW).
9. Switch on your PC and start WindowsTM (minimum requirement: Windows 95TM).
10. Install the "CLV-Setup" software and the online CLV-Setup Help from the CD-ROM
("Manuals & Software") on your PC.
11. Connect the PC to the terminal interface of the CLV.
To do so, connect a 3-core RS 232 data cable (null modem cable), e. g. no. 2 014 054
to the "Aux" plug in the CDB 420 or CDM 490.
12. Start the "CLV-Setup" program.
CLV-Setup establishes communication with the CLV and uploads the parameter set.
The parameters are then displayed on the tabs.
13. Carry out a test read using test bar codes (clock the CLV accordingly).
Display the reading result in the Terminal Emulator window of the "CLV-Setup" program.
14. Configure the CLV for the application using the settings on the tabs in CLV-Setup.
Copy (download) the modified parameter set to the CLV temporarily.
Do not switch off the power to the CDB 420 or CDM 490 (CLV)!
15. Test the application under realistic conditions.
16. Check whether the data is transmitted correctly between the CLV and host.
17. If necessary, correct and optimize the parameter values.
Copy (download) the parameter set permanently to the CLV.
CLV with external parameter memory connected:
Copy the modified parameter set to the external parameter memory when CLV-Setup
asks you for confirmation.
18. Save the parameter set as a configuration file "*.scl" in the "CLV-Setup" program.
The CLV can then be operated with the application-specific settings.

Notes on this document
1.3 Information content
This document contains all the information required to mount, install, and start up the CLV
with the factory settings.
A series of step-by-step instructions is provided for each of these activities.
Configuration of the CLV for the application-specific reading situations is carried out with
the Windows-oriented PC software "CLV-Setup". Further assistance is also available in the
form of the online help system CLV-Setup Help. The procedure for installing and operating
the software is described in the appendix.
For further information on the design of the bar code scanner or on bar code technology in
general, please contact the Division Auto Ident at SICK AG.

Safety information
2Safety information
2.1 Authorized users
For the CLV to function correctly and safely, it must be mounted and operated by sufficiently
qualified personnel.
The end user must be supplied with the operating instructions.
The end user must be provided with expert tuition and is advised to read the operating
instructions.
The following qualifications are required for the various tasks involved:
2.1.1 Mounting and maintenance
•General technical training
•Knowledge of the standard guidelines relating to safety at the workplace
2.1.2 Electrical installation and replacement
•Practical training in electrical engineering
•Knowledge of the standard safety guidelines relating to electrical engineering
•Experience operating the devices in the relevant application (e. g. conveyor belt)
2.1.3 Startup, operation and configuration
•Experience operating the devices in the relevant application (e. g. conveyor belt)
•Knowledge of the hardware and software environment of the relevant application
(e. g. conveyor belt)
•Basic understanding of Windows 95TM/98TM, Windows NT4.0TM, Windows 2000TM or
Windows XPTM
•Ability to use an HTML browser (e. g. Internet ExplorerTM)
•Basic understanding of data transfer methods
•Basic understanding of bar code technology
2.2 Intended use
The CLV is designed to detect and decode bar codes automatically. It is mounted in a
reading station and reads bar codes on objects positioned on a conveyor belt, for example.
In stand-alone configuration the CLV transfers the data content of the decoded bar codes
via its host interface to a host for further processing. Being integrated in the OTS 400 Omni
Tracking System together with other CLVs, the CLV transfers the read results via its CAN in-
terface to the OTC 400 Omni Tracking Controller.
Any warranty claims vis-à-vis SICK AG will be rendered invalid if the device is used for any
other purpose or if changes are made to the device, also as part of the mounting and
electrical installation procedures.
Note Don’t open the device. The producer warranty will be forfeited if the device is opened.

Safety information
2.3 General safety instructions and protection measures
¾Always 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.
Risk of injury by electrical current
In the CDM 490 Connection Module, the optional CMP 490 Power Supply Module is con-
nected to a mains voltage of 100 to 250 V AC/ 50 to 60 Hz.
¾When working with electrical equipment, always follow the relevant safety specifications.
Laser beam can cause blindness.
The CLV 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.
¾As with sunlight, never look directly into the laser beam.
¾Do not direct the laser beam at other persons.
¾Mount and align the CLV in such a way to prevent the laser beam reflecting off mirrored
surfaces.
¾Do not open the housing.
(Opening the housing does not deactivate the laser diode).
¾Observe 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 de-
vice).
Laser warnings
The laser warning symbols (Fig. 2-1) can be found on the CLV at the following locations:
•The laser warning symbol on line scanners is positioned beside the reading window on
the front side of the device. The laser warning in GB English/US English is located on the
side containing the electrical connections (see Fig. 3-1, Page 3-5.)
The additional laser warnings in English applicable to the USA are positioned beside the
reading window on the front side of the device and at the bottom of the device.
•The laser warning symbol on line scanners with oscillating mirror is located above the
reading window, on the cover of the mirror. The laser warning in GB English/US English
is located on the side containing the electrical connections.
The additional laser warnings in English applicable to the USA are positioned below the
reading window on the front side of the device and at the bottom of the front side.
