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
the wide side (
the USA are positioned on the back side of the attachment of the device and at the
back end on the wide side.
Fig. 3-1, Page 3-5). The additional laser warnings in English applicable to
NoteThe device is supplied with an additional set of laser warning labels in German/US English
and in French/US English. If necessary, these can be used to cover the GB English/
US
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
ExplanationThe 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 (seeTable 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
Switch off the power supply or remove the CLV connector from the connection module.
This can result in loss of the following (at the most):
•the application-specific parameter set, if it was only stored temporarily in the CLV
•the last reading result
•daily operating data
(operating hours counter, trigger count, no. of good reads, no. of no reads, maximum
duration trigger, minimum duration trigger, matchcode 1, matchcode 2, no match)
2.4.2Restarting the CLV
Switch on the supply voltage or reattach the connector to the connection module.
The CLV resumes operation with the parameter set that was last stored permanently
and resets the daily operating data.
2.5Environmental information
The CLV is designed to cause minimum impact on the environment. It does not contain any
silicone-based materials on the hosuing surface and, therefore, does not represent any
problems for e.g. paint sprayers in paint shops.
2.5.1Power requirements
The power requirements are particularly low:
•the CLV 420/421/422 line/raster scanners have a max. power consumption of 3.5 W
The value is given for devices with disconnected switching outputs.
2.5.2Disposal after final decommissioning
Always dispose of unusable or irreparable devices in a manner that is not harmful to the
environment and in accordance with the applicable national waste disposal regulations. The
CLV can be separated into recyclable secondary raw materials and special-category waste
(electronic scrap). See
At present, SICK AG does not accept any unusable or irreparable devices.

of the reading result
Status indicator
e. g. Good Read
e. g. No Read
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.
Generates a scan line. Due to the V-principle of beam deflection, the reading field height (for
evaluating the useful length of the scan line) is dependent on the reading distance.
Raster scanner
Generates 8 parallel scan lines that are offset by the same distance. Due to the V-principle
of beam deflection, the reading field height (for evaluating the useful length of the scan lines)
is dependent on the reading distance.
Raster height of the scan line field: 15 mm (0.59 in) at a reading distance of 200 mm
(7.88 in) (front reading window).
3.3Indicators and operating elements
3.3.1Operating elements
The CLV is operated and configured via the terminal interface (auxiliary interface) using the
"CLV Setup" program or using command strings sent via the host interface/terminal
interface. A variety of parameterizing options allow you to adapt the device to a wide range
of applications.
The following can be defined (among others):
•the configuration of the code types to be read
•the reading, evaluation and output characteristics
•the communication parameters of the host interface
•the structure of the data output string for "good read" and "no read" on the host
interface
•the function of the terminal interface
Chapter 10.4 Installation and operating instructions for the PC-based "CLV Setup" program,
Page 10-7 describes the procedure for installing the "CLV Setup" program and how to
operate the user interface. Configuration (parameterizing) is explained in Chapter 6.4
Configuration (parameterizing), Page 6-4.
3.3.2Function of the LED indicators
Four LEDs indicate the operating status, activity of the laser diode, output of the reading
result, and data transfer on the host interface. The LED indicators (
the rear of the device. Table 3-2 shows the meaning of the LED indicators in the different
operating modes/functions.
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

Fig. 4-1: Example line scanner: replacing the laser warning label
4.2.5Selecting 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).
4.2.6Mounting 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.
Depending on the application, the line scanner or raster scanner version of the CLV is used.
Fig. 4-4 shows how the device is aligned with the bar code on the object for each of the two
scanning methods.
Raster scannerLine scanner
Fig. 4-4: Scanning methods: alignment with bar code and conveyor direction
Reading distance between bar code and aperture angle α
The distance between the reading window of the CLV and the bar code must not exceed
the technical limits. The height of the reading field is shown as a function of the reading
distance “a“ for various resolutions (module widths) in
Chapter 10.2 Specification diagrams,
Page 10-1.
Fig. 4-5 shows the definition of the reading distance a from the reading window and of the
aperture angle α for each of the two scanning methods.

Reading distance a
Fig. 4-5: Definition of the reading distance a and the aperture angle α
The useable aperture angle α is max. 50° for both scanning methods, even with the
additional 105
° angle attachment. Due to the V-principle of beam deflection, the reading
field height (for evaluating the useful length of the scan line) depends on the reading
distance.

Table 4-1: Permissible reading angles between the scan line and bar code
Preventing surface reflection
If the light from the scan line strikes the surface of the bar code perpendicularly, interference
may be caused by reflections when the returned light is received. To prevent this effect, the
CLV must be installed in such a way that the emitted light is tilted slightly with respect to the
vertical axis.
Fig. 4-7 shows an example of this using the line scanner.

ExplanationThe CLV can scan and decode several bar codes with each read.
In doing so, it determines the specific local reading diagnosis data for each bar code, i.e. the
position (CP value) of the center of the bar code within the scan line.
Fig. 4-4shows the count direction of the code position.
By determining the CP value, the device can separate identical bar codes (code type, code
length, and data content) and assign the bar code data in the reading result to its position
on the object.
Fig. 4-8: Count direction of the code position CP within the scan line
Tip
In the default setting, the CLV does not output the value "CP" in the reading result of the
host interface. If this is required to evaluate the result in the host, the values can be included
in the Code-Info/Separator block of the output string using the CLV Setup program.

1.Prepare the base for installing the bracket as described in Chapter 4.2.2 Laying out
accessories, Page 4-1.
2.Place the object containing the bar code within the visible range of the CLV (in the
position at which it is to be read) with the conveyor belt switched off.
3.Align the CLV with the bar code (in accordance with the scanning method) in such a way
that
– with the line/raster scanner, the narrow end with the LED indicators is almost parallel
with the bar code surface
– with the line/raster scanner with angle attachment, the wide side with the laser
warning labels is almost parallel with the bar code surface
All of the possible reading angles must be taken into consideration. See Fig. 4-6,
Page 4-5.
4.If relevant to the evaluation, pay attention to the count direction of the code position if
applicable. See
5.Install the CLV bracket on the base.
Fig. 4-8, Page 4-6.
Risk of damage to the device
The maximum depth of engagement of the two tapped blind holes M4 is 6 mm (0.24 in).
Longer screws will damage the device.
Use screws with the correct length.
6.Screw the M4 screws through the bracket into the tapped blind holes of the CLV.
7.Tighten the screws slightly.
8.Adjust the CLV as described below.
4.3.2Adjusting the CLV
The "percentage evaluation" mode supports the adjustment of the CLV. In this mode, the
CLV displays the quality of the bar code reads that enter the CLV reading field statically (the
object is not moved on the conveyor belt). The CLV performs 100 scans in Free Running
mode and evaluates the reading quality statistically. It outputs the reading result
continuously every 2 s via the terminal interface.
The behavior of the "Result" LED also indicates the reading quality:
• If the LED does not light up, the CLV cannot read the bar code
(reading quality < 30 %).
•If the LED blinks, the CLV is having problems reading the bar code
(reading quality 30 % to 90 %).
•When the LED lights up constantly, the CLV is aligned optimally
(reading quality > 90 %). The scanning frequency in the default setting is 700 Hz.
1.Connect the CLV to the CDB 420 or CDM 420 connection module and switch on the
power supply to the module (see
Page 5-5).
Once the CLV has started, it outputs a tone to indicate that the self-test was
successfully completed. Shortly afterwards, it outputs two tones to indicate that it has
assumed Reading mode. The "Device Ready" LED lights up.
2.Connect the PC to the terminal interface of the CLV. For this purpose, connect a 3-core

2.Position the CLV in such a way that the center of the scan line (indicated by the end of
the visible scan line, code position CP = 50) is located at the center of the bar code, or
at the center of the field for all codes if several bar codes are used.
Show CP-limits
The "Show CP-limits" operating mode enables you to test whether a limit placed on the
active evaluation range of the scan line via parameterization has had the desired effects.
For this purpose, the CLV alternately masks out a certain part of the scan line corresponding
to the selected minimum and maximum values of the code position.
For information on calling up this operating mode and for checking procedures, see
Chapter 6.5.4 Show CP-limits, Page 6-19.

the vicinity of the CLV. The "Sensor 1" switching input is selected as the default trigger
source for this trigger type.
Fig. 4-10 shows two examples of where a photoelectric reflex switch can be installed. This
depends on the distance a from the bar code to the front edge of the object. Depending on
the application, you may need to attach the sensor in such a way that bar codes on objects
of different sizes can be read completely during the reading interval.

Table 4-2: Permissible range values for the polling reflectors
ExplanationWhen reflector polling is used, the CLV activates the laser diode with every 20th scan and
checks whether it detects the reflector. If the reflector is visible, the CLV repeats the
procedure after the next 20 scans. If the reflector is concealed by an object entering the
reading field, the CLV starts the reading pulse. This pulse ends when the CLV detects the
reflector again. Following this, the CLV repeats the above procedure. When the CLV is
switched on, the polling reflector must be visible before the first reading pulse can start. The
CLV does not output the data content of the polling reflector in "Reading" mode.
NoteThis pulse mode is not suitable for applications where time is critical. The max. delay
between the reliable detection of the reflector and the start of the internal reading interval
is approx.
25 ms at a scanning rate of 800 Hz.
Adjusting the polling reflector roughly
1.Connect the CLV to the CDB 420 or CDM 420 connection module and switch on the
Once the CLV has started, it outputs a tone to indicate that the self-test was

Page 4-11. Other ranges available on request.
4.Secure the polling reflector directly opposite the CLV on a suitable base (movable
bracket, wall) temporarily so that the CLV has an unobstructed view of the reflector in
the gaps between the objects and can scan them reliably. The reflector must be in the
center of the scan line, see

5.4.2Power supply
The CLV requires a power supply of 10 to 30 V DC (functional extra-low voltage) in
accordance with the standard IEC
generated by using a safety isolating transformer pursuant to IEC
364-4-41. The functional extra-low voltage can be
742. The CLV has a
power consumption of max. 3.5 W (when switching outputs are not connected).
The CLV is supplied with 10 to 30 V DC via the CDB 420 or CDM 420 connection module.
If an optional CMF 400 field bus gateway or a CMD 400 Connection Module Display is
additionally used in the CDM 420, the ICR is supplied with 18 to 30
V DC.
If the CMP 400 Power Supply Module is used in the CDM 420, a mains voltage of 100 to
250 V AC/50 to 60 Hz is required.
NoteThe CLV 42x is UL certificated when a class 2 power supply according to UL 1310 is used.

The CLV is configured locally in accordance with the application at hand. The read, evaluation
and output characteristics can be parameterized as required. The factory default settings or
an application-specific parameter set of the CLV are in effect before changes are made.
The CLV supports four different configuration methods:
•Configuration via the "CLV Setup" program and the CLV Assistant
(parameter values are set via the serial interface).
•Configuration via AutoSetup
(reading and code configurations for a bar code are adapted automatically via the
optical interface (reading window)),
seeChapter 6.4.4 Configuring the CLV with AutoSetup, Page 6-10.
•Configuration via profile bar codes
(parameter values are set via the optical interface (reading window)),
see Chapter 10.5 Configuring the CLV with profile bar codes, Page 10-17.
•Configuration via command strings
(parameter values are set via the serial interface),
seeChapter 10.6 Configuring the CLV with command strings, Page 10-22.
In Parameter mode, the CLV only outputs a reading result with AutoSetup.
6.4.1Configuring CLV with the user interface of CLV Setup
To be able to use "CLV Setup", a PC has to be connected and the program installed on it.
The procedure for connecting the PC to the CLV is described in
the PC, Page 5-7. Installation and startup of "CLV Setup" and operation of the user interface
are described in the appendix. See Chapter 10.4 Installation and operating instructions for
the PC-based "CLV Setup" program, Page 10-7.
Transferring parameter sets between CLV Setup and the CLV
Upload
When the CLV is being parameterized, CLV-Setup runs in the offline mode. To be able to
modify the current parameter set of the CLV, this first has to be loaded to CLV-Setup from
the CLV. This procedure is referred to as an
Setup always loads a complete copy of the current CLV parameter set. This parameter set
remains unchanged until it is overwritten by CLV-Setup.
With the help of the context menu (right mouse button), only the parameter just edited can
be loaded ("Upload parameter") or from version 3.6 all parameters of one tab or one dialog
box ("Upload parameters of this view") from the CLV’s memory (RAM).
Download
Changes made to the current parameter set in CLV-Setup do not take effect until the parameter set has been transferred to the CLV. CLV-Setup always sends a copy of the complete parameter set to the CLV, i. e. all of the existing parameter values in the CLV are
overwritten. The procedure for transferring and saving the parameter values in the CLV is
referred to as a
With the help of the context menu (right mouse button), only the parameter just edited
("Download parameter") or from version 3.6 all parameters of one tab or one dialog box

again to the CLV with the "Permanent" option.
Loading complete parameter set from the CLV (upload)
Click in the toolbar.
CLV Setup loads the current CLV parameter set from the RAM of the CLV to its database
and displays the values on the tabs.
The "Device Ready" LED is extinguished during the upload.
If the "CLV Setup" program does not recognize the parameters transferred during the
upload, it outputs a warning. Unknown parameters can be edited on the
EXTRAS tab by
following the conventions for command strings. When the parameter set is saved, these
parameters are also taken into account.
Transferring the complete parameter set to the CLV and saving it (download)
1.Click in the toolbar.

6.4.4Configuring the CLV with AutoSetup
AutoSetup enables the reading and code configurations of the CLV to be adapted automatically to the application at hand. The following conditions must be fulfilled with regard to this:
•one bar code (code type, code length)
•fixed reading distance
•conveyor belt off (static reading)
The CLV determines the code type, code length and the most favorable scanning rate for
the bar code presented. This takes place in Free Running mode. Once AutoSetup has been
completed successfully, the CLV copies the parameter values determined to its parameter
set.
All other code types and code lengths are then disabled. If AutoSetup was not
completed successfully, the parameter set is not changed. The CLV does not read a
Pharmacode or any EAN/UPC types in AutoSetup. It does not respond to an external reading
pulse.
AutoSetup can be activated in three different ways in the CLV:
•via the user interface of CLV Setup
•by presenting profile bar code no. 10 (on the card supplied) to the optical interface
(reading window).
See Chapter 10.5.1 Activating AutoSetup with a profile bar code,
Page 10-17.
•via a command string (via the serial interface). See Chapter 10.6 Configuring the CLV
with command strings, Page 10-22.
While AutoSetup is running, the CLV outputs the step-by-step changes made to the
parameter values in the search mode and the determined diagnosis data via the terminal
interface in the form of a list. The list can be displayed, for example, in the terminal emulator
of CLV Setup. Once AutoSetup has been completed, appropriate error messages are output
for diagnosed malfunctions in the event of a no read.
ExplanationAutoSetup procedure
1.Starting at 400 Hz, the CLV increases its scanning frequency to 1,200 Hz in steps of
100 Hz. It evaluates the reading quality of 100 scans for each step.
2.The CLV performs verification reads +/– 50 Hz around the scanning frequency with the
highest reading quality.
3.It then copies the optimum scanning frequency, the code type and code length to its
parameter set.
Activating AutoSetup via the user interface of CLV Setup
In CLV Setup, AutoSetup can be started by choosing the appropriate menu path, via the
terminal emulator or as an executable device function (interactively). Due to the better
display of the progressing procedure, we recommend starting AutoSetup via the terminal
emulator.
Preparing AutoSetup:
1.Switch on the power supply of the CDB 420 or CDM 420 connection module (of the
CLV).
After the CLV has started, it emits a tone to indicate that the self-test was successful.
After a short while, it outputs two consecutive tones to indicate that it has switched to
reading mode. The "Device Ready" LED lights up.
2.Upload the current parameter set from the CLV with CLV Setup (the parameter set
initially contains the factory default settings).
CLV Setup displays the current values on the tabs.
3.AutoSetup overwrites important values in the current parameter set of the CLV.
Save the existing parameter set as a configuration file "*.scl" in CLV Setup before you
change the parameter settings.
See Chapter 6.4.1 Configuring CLV with the user
interface of CLV Setup, Page 6-4.
Performing AutoSetup:
1.Click in the toolbar.
The terminal emulator is launched. The CLV is in reading mode.
2.Present the application-specific bar code to the CLV at the maximum reading distance
for the application. Note the limits of the CLV here. See
reading field diagrams in
Chapter 10.2 Specification diagrams, Page 10-1.
To prevent surface reflections, rotate the bar code towards the CLV approximately 15°
away from the vertical axis. See
Fig. 4-7, Page 4-5.
3.Click AUTO SETUP under DEVICE MODE.
The CLV cancels reading mode. The "Device Ready" LED is extinguished.
The CLV then starts AutoSetup.
The red scan line appears when the "Laser On" LED lights up.
4.The CLV then runs AutoSetup and continuously displays the changes to the parameter
values in the terminal emulator (
Fig. 6-2, Page 6-12).
5.The CLV confirms that AutoSetup has been completed successfully by outputting two
consecutive tones via the beeper and activating the "Result" LED for 100 ms (default
setting). To begin with, it only overwrites the appropriate parameter values in the RAM.
The CLV returns to reading mode. The "Device Ready" LED lights up. The READING MODE
radio button in the terminal emulator is not, however, displayed as the active device
mode again. The CLV only evaluates the presented code type and length the next time
a bar code is read.
6.Perform an upload from the CLV. This is done by clicking in the toolbar.
CLV loads the current parameter set from the RAM of the CLV and displays the new
values in the tabs.
7.Perform a download to the CLV. This is done by clicking in the toolbar.
The DOWNLOAD PARAMETER dialog box is displayed.
8.Confirm the dialog box by selecting the PERMANENT save option.
The CLV saves the changes made to the parameter set permanently in the EEPROM.
9.Close the terminal emulator.

AutoSetup canceled by the CLV in the event of a no read:
If the CLV was not able to execute AutoSetup successfully, it cancels the search mode after
the last increase made to the parameter values by outputting a long tone via the beeper.
Depending on the reason for AutoSetup being terminated, it outputs one of the following
error messages via the terminal Interface:
"No valid code found" (no valid bar code found or reading quality less than 75 %)
"Cancel AutoSetup" (AutoSetup terminates)
– or –
"More than one code found"
"Cancel AutoSetup" (AutoSetup terminates)
The current parameter set in the CLV does not change.
The CLV returns to reading mode.
The "Device Ready" LED lights up.
Running AutoSetup again:
1.Click READING MODE under DEVICE MODE.
The CLV switches to reading mode.
2.Click AUTO SETUP under DEVICE MODE again.
The CLV then starts AutoSetup.
3.If AutoSetup is unsuccessful again, check whether the CLV is able to read the bar code
correctly (reading distance, tilt, more than one bar code in the reading field).
Terminating AutoSetup prematurely:
It is not possible to abort AutoSetup here.
To prevent parameter values in the RAM of the CLV from being overwritten, move the
bar code away from the reading field and wait for the CLV to output an error message
(AutoSetup must not supply invalid settings).
Checking parameter values stored in the CLV (after parameters are saved):
1.Switch the power supply of the connection module (of the CLV) off and on again.
2.Perform an upload from the CLV. This is done by clicking in the toolbar.
3.Check the values in the READING CONFIGURATION and CODE CONFIGURATION tabs.
Only one code type may be active on the CODE CONFIGURATION tab.
NoteThe CLV does not enter a real value in the parameter set for the parameter "Minimum Bar
Width", as it is not able to determine any absolute dimensions. This is why the value
displayed on the
READING CONFIGURATION tab does not match the actual conditions.
Checking the stored read and code configurations:
Once AutoSetup has been completed successfully, check the CLV settings as follows:
1.Click in the toolbar.
The TERMINAL EMULATOR is launched. The CLV is in reading mode.
2.Click PERCENT EVALUATION under DEVICE MODE.
The dialog box for the distance configuration is then displayed.
3.Confirm the dialog box with "OK".
The CLV starts the percentage evaluation and displays the reading quality of each set
of 100 scans continuously. See
Chapter 6.5.2 Percentage evaluation, Page 6-17.
4.Present the application-specific bar code at the distance taught in (at the minimum and
maximum reading distance if the bar code in the application is in a variable reading
range).
5.Check the reading quality in the terminal emulator. This should be between
70

6.5.1Reading mode (standard operating mode)
The CLV performs a self-test after it has been switched on. It is then set to the reading mode
and confirms this by outputting two consecutive tones via the beeper. In the default setting,
the "Sensor 1" switching input is the (external) trigger source of the reading pulse. The
reading result is output by the CLV at the end of the reading pulse via the host interface
(default setting) and terminal interface.
The reading result of the terminal interface can be displayed in the CLV Setup terminal
emulator. The CLV terminal interface must be set to the
purpose. This mode is selected for the default setting. The reading result of the terminal
interface has a fixed, invariable format.
The READING MODE can be called up by choosing VIEW in the menu bar or via the terminal
emulator.
Displaying the reading result in the terminal emulator
1.Click in the toolbar.
The TERMINAL EMULATOR dialog box is then displayed.
2.Click READING MODE under DEVICE MODE.
3.Present the bar code pattern from Fig. 6-1, Page 6-3 to the CLV and activate the
reading pulse. The "Laser On" LED lights up. The red scan line then appears.
See also Chapter 6.3.1 Starting up the line/raster scanner with the factory default
settings, Page 6-3.
4.Terminate reading pulse.
The CLV outputs a tone via the beeper to indicate that the reading result is displayed in
the window of the T
ERMINAL EMULATOR. The "Result" LED lights up for duration of 100 ms
(default setting).
Fig. 6-3 shows two examples of reading result output: "good read" and "no read". The
reading result comprises the data contents of the bar code(s) and the reading diagnosis
data
. Fig. 6-4 explains the structure and function of the reading diagnosis data for good
read, and Fig. 6-5for no read.
NoteThe CLV only outputs several bar codes in the reading result of the host interface if the
parameterized minimum and maximum number of bar codes is > 1, and several bar codes
have been presented. The number of bar codes to be read/output for each reading interval
can be selected on the
CODE CONFIGURATION tab in the NUMBEROF CODES group.
The reading result of the host interface can also be displayed.
Chapter 6.5.7 Monitor host interface, Page 6-21 describes the procedure and the structure
of the read result in the default setting.

8.Click the SW-TRIGGER OFF button or press [F8].
CLV Setup sends a stop command to the CLV.
The "Laser On" LED is extinguished. The CLV switches off the laser diode.
The CLV outputs a tone via the beeper to indicate that the reading result is displayed in
the output window of the terminal emulator. The "Result" LED lights up for a duration of
100 ms (default setting).
6.5.2Percentage evaluation
In the Percentage evaluation mode, the reading quality of bar codes which enter the reading
field of the CLV and are not moved (conveyor off) is assessed.

6.5.3Adjusting mode
The Adjusting mode enables the center of the scan line to be optimally positioned on the
bar code.
Chapter 4.3.3 Auxiliary functions for adjustment, Page 4-8 describes the
procedure for going about this after the Adjusting mode has been called up. The CLV does
not output a reading result in this mode.
The Adjusting mode can be called up by choosing VIEW in the menu bar, as a DEVICEFUNCTION
via
CLV 42X (interactively) or via the terminal emulator.
1.Click in the toolbar.
The terminal emulator window is then displayed. The CLV is in reading mode.
2.Click ADJUSTING MODE under DEVICE MODE.
The "Device Ready" LED is extinguished. The CLV cancels the reading mode and masks
the scan line from position CP
= 50 to position CP = 100.
3.Choose READING MODE to exit the Adjusting mode.
The CLV returns to reading mode. The "Device Ready" LED lights up.
In this mode, the CLV masks certain parts of the scan line so that any limit values defined
for the active evaluation range of the scan line can be checked directly during
parameterization. The restricted active evaluation range shortens the evaluation time for
fast applications, for example, because the evaluation routine needs only take account of
unmasked parts of the scan line. The range is restricted by entering appropriate values for
MINIMUM CODE POSITION and MAXIMUM CODE POSITION in the CODE POSITION section on the
READING CONFIGURATION tab or under DYNAMIC READING CONFIGURATION. The CLV does not
output a reading result.
SHOW CP-LIMITS can be called up via CLV 42X, DEVICEFUNCTIONS (interactively).
The CLV masks the scan line alternately from the set value for CP

6.5.6Reading diagnosis
Function of the terminal interface. In this mode, the CLV outputs the data contents of all
the bar codes that were read – including those that, according to the evaluation criteria,
were not read properly and were thus incorrect – together with the associated reading
diagnosis data via the terminal interface. The number of bar codes output can, therefore, be
higher than the number of those that were sent via the host interface in the reading result.
In the default setting, this mode is selected for the terminal interface.

Example: „0123412345“.
Fig. 6-9: CLV Setup: output of the reading result of the host interface in the terminal emulator at
the beginning (in this case: O
= Output)
NoteLarge amounts of data received at high speeds via the host interface and high data transfer
rates may cause the flow of host interface traffic to no longer be completely displayed on
the terminal interface (display "…").
This is caused by the slower data transfer speed of the terminal interface (9,600 bd).
In the default setting, the CLV transmits the following data string via the host interface:
•Good Read: the data content of the bar code(s)
•No Read: the NOREAD string
The “Header“, “Code Info/Separator“, “Splitter“ and “Terminator“ blocks are blank.
Tip
The structure of the data output string of the host interface can be configured via the DATA
S
TRINGS tab:
•Up to 10 elements, consisting of constants (control characters, letters, digits) and/or
reading diagnosis data, can be entered in the “Header“, “Code Info/Separator“ and
“Terminator“ blocks .
•Up to 5 elements, consisting of constants (control characters, letters, digits), can be
entered in the “Splitter“ block.
•The position of the “CodeInfo/Separator“ block can be choosen before or after the
Code.
1.Select the DATA STRINGS tab.

6.5.8Auxiliary input
Function of the terminal interface. In this mode, the CLV accepts a bar code entered at the
terminal interface (via the keyboard or hand-held scanner with decoder). It sends the bar
code to the host in a separate data string via its host interface. No reads can, therefore, be
corrected by transmitting missing bar codes subsequently.
Chapter 10.9.2 Auxiliary input via terminal interface, Page 10-31 describes this function and
the associated procedure in greater detail.
6.5.9Self-test
After the CLV has been switched on, it performs a self-test before it is initialized with the
parameter set. The test can be called up explicitly at any time via CLV Setup. During the selftest, the CLV checks that its hardware components are functioning correctly. A final
message via the terminal interface provides information on the test result. The CLV does not
output a reading result during the test routine.
1.Click in the toolbar.
The terminal emulator window is then displayed.
The CLV is in reading mode.
2.Click SELF TEST under DEVICE MODE.
The "Device Ready" LED is extinguished. The CLV cancels the reading mode and starts
the test routine.
After a few seconds, the CLV outputs the encoded test result in the form of a code
number (

To ensure optimum reading performance, the reading window of the CLV must be clean at
all times.
For this reason, we recommend that you check the reading window at regular intervals,
particularly if the device is operated under extreme conditions (dust, abrasion, humidity,
finger prints).
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.
As with sunlight, never look directly into the laser beam.
Switch off the device while it is being cleaned.
Never look directly into the reading window while the device is in operation.
Damage to the reading window
The reading window is made of glass. Scratches and streaks on the window will reduce the
reading performance.
Use a mild, non-scouring detergent.
Never use scratching or scouring motions to clean the reading window.
Cleaning reading window
Clean the reading window at regular intervals with a mild, non-scouring detergent, e.g.
an antistatic glass cleaning fluid.

frequency and the reading distance
8.1.4Malfunctions during operation
•Laser timeout for laser diode elapsed
•Device error (hardware/software)
8.2Monitoring errors and malfunctions
The CLV is self-monitoring:
•After the power supply has been switched on, the CLV automatically carries out a selftest, in which it checks important hardware components, before it is initialized (loading
of parameter set and initializing of device functions). The self-test can be repeated at
any time by canceling reading mode. For calling up, see
Page 6-23.
•If the CLV detects an error during the self-test or at any other time, it outputs the error
status ST=3 via the host interface. Prerequisite: the error status is enabled for
transmission. By default, transfer is blocked.
The CLV displays the diagnosed error as a numeric combination in the fourth field from
the left on the bottom, in the status line of CLV Setup (
•While it is in operation, the CLV constantly monitors the laser diode and speed of the
polygon mirror wheel. In addition, a watchdog circuit responds to error statuses.
•A timer automatically deactivates the laser diode 10 minutes (default setting) after a
continuous reading pulse is initiated in reading mode with switching input pulse modes
