Installation procedure (overview)
Reading trigger via “Sensor“ switching input (default setting)
1. Check the deliver to make sure that none of the components is missing.
2. Mount the CLV at the reading station and align it with the object carr ing the bar code.
3. Mount the AMV/S 60 Connection Module.
4. Connect the CLV to the AMV/S 60 Connection Module using the two cables
no. 2 020 302.
Alternativel , connect the device to the AMV/S 60 via the external parameter memor
no. 2 020 307.
5. Connect the reading pulse sensor to the "Sensor" switching input in the AMV/S 60.
6. Connect the host to the host interface in the AMV/S 60.
Adapt the AMV/S 60 to the host interface t pe of the CLV.
7. Switch on the power suppl to the AMV/S 60.
The "Device Read " LED lights up after the CLV has started.
CLV with external parameter memory connected:
The "Device Read " LED and the "Read Result" LEDs blink after the CLV has started.
The CLV is not read to start reading. See step 11.
Line scanner with oscillating mirror:
In the default setting, the CLV deflects the scan line around the position CW = 50 with
a frequenc of 1 Hz and an oscillating amplitude of max. ±20° (±40 CW).
8. Switch on our PC and start WindowsTM (minimum requirement: Windows 95TM).
9. Install the "CLV-Setup" software, online CLV-Setup Help and, if necessar , the
I-ViewProTM HTML browser from the CD on our PC.
10. Connect the PC to the terminal interface of the CLV. To do so, connect the RS 232 data
connection cable (e. g. no. 2 014 054) to the "Service plug" in the AMV/S 60.
11. Start the "CLV-Setup" program.
CLV-Setup establishes communication with the CLV and uploads the parameter set.
The parameters are then displa ed on the tabs.
CLV with external parameter memory connected:
First download the CLV parameter set to the external memor .
Disconnect the AMV/S 60 briefl from the power suppl to restart the CLV.
12. Carr out a test read using test bar codes (clock the CLV accordingl ).
Displa the reading result in the Terminal Emulator window of the "CLV-Setup" program.
13. Configure the CLV for the application using the settings on the tabs in CLV-Setup.
Cop (download) the modified parameter set to the CLV temporaril .
Do not switch off the power to the AMV/S 60 (CLV)!
14. Test the application under realistic conditions.
15. Check whether the data is transmitted correctl between the CLV and host.
16. If necessar , correct and optimize the parameter values.
Cop (download) the parameter set permanently to the CLV.
CLV with external parameter memory connected:
Cop the modified parameter set to the external parameter memor .
17. 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.

2.2 Intended use
The CLV is designed to detect and decode bar codes automaticall . It is mounted in a
reading station and reads bar codes on objects positioned on a conve or belt, for example.
The CLV transfers the data content of the decoded bar codes via its host interface to a host
for further processing.
An warrant claims vis-à-vis SICK AG will be rendered invalid if the device is used for an
other purpose or if changes are made to the device, also as part of the mounting and
electrical installation procedures.

Safety information
Shock hazard!
Depending on the t pe of device, the AMS 60 Connection Module (accessor ) for the CLV
is connected to a mains voltage of 230 V AC 50 Hz or 115 V AC 50/60 Hz.
¾
When working with electrical equipment, alwa s follow the relevant safet 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.
¾
Never look directl into the path of the beam (similar to sunlight).
¾
Do not direct the laser beam at other persons.
¾
When mounting and aligning the CLV, avoid reflections caused b reflective surfaces.
¾
Do not open the housing.
(Opening the housing does not deactivate the laser diode.)
¾
Observe the most recent laser specifications (DIN EN 60825-1, 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.
Laser warnings
The laser warning s mbols applicable for Europe (Fig. 2-1) can be found on the CLV at the
following locations:
•The laser warning s mbol on line scanners is positioned beside the reading window on
the front side of the device. The GB/US laser warning is located on the side containing
the electrical connections (see Fig. 3-1, Page 3-4.)
•The laser warning s mbol on line scanners with oscillating mirror is located above the
reading window, on the cover of the mirror. The GB/US laser warning is located on the
side containing the electrical connections.

Safety information
Note A set of laser warnings in German/US English and French/US English is included in the
deliver scope. The GB English/US English warnings can be pasted over with these if
necessar .
If the CLV is installed in a machine/panel with the result that the laser warning labels
are no longer visible, additional warnings (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 CLV 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 b the reading pulse trigger.
A timer (laser timeout) automaticall 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
CLV outputs the message:
"Laser safety timeout"
on the terminal interface. The reading interval must be terminated b resetting the trigger
signal. The laser diode is activated again b the next reading trigger.
In the Percentage Evaluation mode, Adjusting mode and Show CP-limits as well as in
the Free-running Reading mode the laser diode is constantly activated.
Note In the Reading mode, the CLV carries out a distance measurement referencing at regular
intervals. During referencing, it turns the laser diode on for a maximum of 10 seconds.
2.4 Quick stop and quick restart
2.4.1 Stopping the CLV
¾
Switch off the power suppl .
This can result in loss of the following (at the most):
•The application-specific parameter set, if it was stored temporarily in the CLV
•The last reading result
•Dail operating data
(operating hours counter, number of reading intervals, Good Read count, maximum
duration trigger, minimum duration trigger, average identification qualit )
2.4.2 Restarting the CLV
¾
Switch on the power suppl .
The CLV resumes operation with the parameter set that was last stored permanently
and reset the dail operating data.
