Operating Instructions
CLV 42x bar code scanner
Installation procedure (overview)
Reading pulses via switching input "Sensor 1" (default setting)
1. Check scope of delivery for completeness.
2. Install the CLV at the reading station and align it with an object possessing a bar code.
3. Install the CDB 420 or CDM 420 connection module.
4. Connect the CLV to the CDB 420 or CDM 420 connection module.
5. Install the reading pulse sensor.
6. Connect the reading pulse sensor to the "Sensor 1" switching input in the CDB 420 or
CDM 420.
7. Connect the host to the "host interface" in the CDB 420 or CDM 420.
8. Switch on the power supply to the CDB 420 or CDM 420.
After the CLV has been started, the "Device Ready" LED lights up. The beeper signals
that reading mode has been started by means of two consecutive sounds.
9. Switch on PC and start WindowsTM (at least Windows 95TM required).
10. Install accompanying user software "CLV Setup" and online help "CLV Setup Help"
from CD-ROM (“Manuals & Software“) to PC.
11. Connect the PC to the terminal interface of the CLV.
For this purpose, connect the PC via a 3-core RS 232 data cable (null modem cable)
to the "Aux" plug in the CDB 420 or CDM 420.
12. Start "CLV Setup" user software.
CLV Setup starts the communication with the CLV and copies the parameter set of the
CLV via an upload. The parameter set is displayed on tabs.
13. Carry out a test read with the test bar code sample (clock the CLV accordingly).
Display the reading result in the terminal emulator of CLV Setup.
14. Configure the CLV for the application by means of the setting options on the tabs
in CLV Setup.
Copy the modified parameter set temporarily to the CLV via download.
Do not switch off the power supply of the CDB 420 or CDM 420 (of the CLV)!
15. Run a test under realistic conditions.
16. Check proper data transfer of the CLV to the host.
17. Correct and optimize the set parameter values if necessary.
Copy the parameter set to the CLV permanently via download.
18. Save the parameter set as a "*.scl" configuration file in CLV Setup.
The CLV contains application-specific settings and is ready for operation.

Safety information
CLV 42x bar code scanner
2.3 General safety instructions and protection measures
Carefully read the general safety instructions and observe them at all times. This also
applies to the warnings provided for the activities described in each chapter of this
document.
Risk of injury by electrical current
In the CDM 420 Connection Module, the optional CMP 400 Power Supply Module is
connected to a mains voltage of 100 to 250 V AC/50 to 60 Hz
When working with electrical equipment, always follow the relevant safety regulations.
Laser radiation can seriously damage your eyesight.
The CLV uses a class 2 red-light laser. Looking directly at the laser beam can seriously
damage the retina in your eyes.
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.
As with sunlight, never look directly into the laser beam.
Do not direct the laser beam at other persons.
Mount and align the CLV in such a way to prevent the laser beam reflecting off mirrored
surfaces.
Do not open the housing.
(Opening the housing does not deactivate the laser diode).
Observe the laser protection specifications (latest version).
.
Laser power
The laser operates at a wavelength of λ = 650 to 670 nm (visible red light). The power
output of the laser beam at the reading window is max. 3.6 mW (CLV 421). The emitted
beam 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).
Laser warnings
The laser warning labels (Fig. 2-1) are attached at the following positions on the CLV:
• The laser warning symbol and the laser warning in GB English/US English on line/raster
scanners are positioned beside the reading window on the wide side of the device
(
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 back
end on the wide side.
• The laser warning symbol and the laser warning in GB English/US English on line/raster
scanners with a 105° angle attachment are positioned beside the reading window on

English warning.
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
Explanation The CLV is equipped with monitoring circuit-breakers that switch off the laser diode if
problems arise with the laser beam.
No maintenance required to keep this product in
compliance with laser class II.
Activation and deactivation of the laser diode when reading is controlled by the reading
pulse (trigger source).
A timer (laser timeout) automatically deactivates the laser diode 10 minutes (default setting)
after a continuous reading pulse is initiated in reading mode with switching input pulse
modes "Sensor Input" and "Serial Interface". In this case, the CLV outputs the message:
"Laser safety timeout" via the terminal interface.
The reading pulse interval is to be terminated by resetting the pulse signal. The laser diode
is activated again by the next reading pulse.
The laser timeout can be set in the range of 1 min to 25 h or deactivated (see Table 6-4,
Page 6-8).
In the "Percentage Evaluation" mode, "Adjusting" mode, "Show CP-limits" and
"AutoSetup" mode as well as in the pulse modes "Free Running" and “Continuous
Read“, in reading mode, the laser diode is constantly activated. In the "reflector
polling" trigger mode the laser diode is switched on for each 20th
scan.

3.2 Method of operation
The CLV first scans the bar code with a scan line and then decodes it. The CLV forwards the
data via the serial host interface (main data interface) to a host/PC for further processing.

The tried and tested standard decoder of the CLV series is available for decoding.
The CLV derives useful diagnosis data from the reading process and transfers it 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 a reading process when an object is located in the reading field, the CLV requires a
suitable trigger. This opens a time window ("reading interval") in the CLV for the reading
procedure. In the default setting, this trigger is supplied by an external reading pulse sensor.
Alternative trigger sources include reflector polling, free-running mode or a command via the
host interface.
The current operating status is indicated by four LEDs.
A beeper indicates the status of the reading result. In the default setting, the "Good Read"
function is selected for this.
If the trigger is supplied externally by a sensor, the "Sensor 1" switching input signals the
start of the reading procedure to the CLV. The "Sensor 2" switching input can be used to
teach in a match code. The "Result 1" and "Result 2" switching outputs can be assigned
various functions and trigger external devices, such as a PLC.
The CLV is operated and configured via the serial terminal interface (auxiliary interface) using
the "CLV Setup" software or via the host/terminal interface and command strings.
System messages, warnings and error messages help you with configuration and with
locating the source of errors during startup and in reading mode.

3.3.3 Function of the beeper
The beeper uses different tone sequences and lengths (Table 3-3) to signal whether
functions have been executed successfully and whether any malfunctions have occurred.
For information on troubleshooting, see Chapter 8.5 Troubleshooting, Page 8-5.
In the default setting, the beeper indicates the event status "Good Read" by means of a
"Low" (quiet) beep. It is assumed in these operating instructions, that the beeper is
operated with the default setting in Reading mode.
The sound opening of the beeper is located on the rear, narrow side of the device and below
the LED labeling.
Operating mode Tone sequence Beeper function
Start Beep • signals that the self-test after power-up was successful
Reading mode Beep Beep • confirms that the device has assumed Reading mode after power up
and after the wait time of 5 s for reading the profile bar codes has
elapsed
Beep • confirms a successful read (good read; default setting) and the reading
result output
Profile programming
Start AutoSetup
Profile programming Beep • confirms successful read of profile bar code
Exceeding the laser timeout Beep Beep Beep • signals that the laser diode has been deactivated after the laser timeout
Table 3-3: Beeper function
Tip
Beep • confirms successful read of profile bar code for start/end of AutoSetup
Beep Beep • confirms successful read of application-specific bar code and start of
reading mode
Beep (long tone) • signals that the application-specific bar code was not read
Beep Beep • confirms start of reading mode 10 s after last profile bar code was read
of 10 min (default setting) was exceeded in Reading mode. The reading
pulse is still active.
The behavior of the beeper in reading mode can be changed on the DEVICE CONFIGURATION
tab in the CLV Setup program.

4.2.4 Replacing the laser warning label
If necessary, replace the laser warning label in GB English/US English on the CLV with the
required language (
Fig. 4-1).
The device is delivered with a set of laser warnings in:
• German/US English
• French/US English
See also Chapter 2.3 General safety instructions and protection measures, Page 2-2.
Included label set:
(set for CLV 421 pictured here)
Fig. 4-1: Example line scanner: replacing the laser warning label
4.2.5 Selecting the installation location
When you select the installation location, the distance between the CLV and the host and
between the CLV and the bar code are important.
Distance between the CLV and the host
The CLV can be installed without a connection to the SICK CAN Scanner Network or to a bus
connection max.
1,200 m (3,936.96 ft) away from the host. The distance which can be
achieved depends on the selected model of the host interface and the set data transfer
rate, however. See
Table 5-2, Page 5-3.
Distance between the CLV and the CDB 420 or CDM 420 connection module
The CDB 420 or CDM 420 connection module must not be located further than 10 m
(32.8 ft) away from the CLV, since the "CLV Setup" program on the PC accesses the
terminal interface of the CLV via this module (RS 232).
4.2.6 Mounting accessories
The CLV is mounted with the help of two tapped blind holes (M4) located on the bottom
narrow side of the device.
Fig. 4-2 shows the position of the threaded hole for both housing
models. The complete dimensions of the CLV housing are shown in Fig. 9-1, Page 9-3.
