Laser radiation!
The radiation emitted by the laser diode (red or IR light) on the CLV 410 is harmful to
the human eye. For this reason, do not look directly into the laser beam.
WARNING!
Opening the housing while the device is in operation does not prevent the laser diode
from being activated by the reading pulse.
The maximum output power of the laser beam at the reading window is 1 . 2 mW.
The CLV, therefore, is assigned to protection class 2.
Laser radiation, do not stare into the beam, class 2 laser product.

Clock button on the programming adapter. For this purpose, choose the pulse mode
via the E
DIT READING PULSE field on the DEVICE CONFIGURATION card of the user interface
and download it to the CLV.
8. 5 Connecting the interfaces
All of the interfaces are routed via the 15-pin D Sub HD connector À (Table 3).
8. 5. 1 Connecting the host interface
The CLV is equipped with two host interfaces (RS 232 and RS 422/485). One of
these must be selected for data communication with the host/PC. If the RS 232
interface is not connected to the host, it can be used exclusively to monitor data
traffic on the parallel RS 422/482 interface.
The internal modules of the CLV may be damaged irreparably if the data interface
is connected incorreclty.
Ø Connect the host interface of the CLV to the host in accordance with the EMC
requirements using shielded cables(Fig. 4)
Ø To prevent interference, do not lay the data cables over a long distance parallel
to the power supply and motor cables, e.g. in cable ducts
Ø Apply the shield on one side (SICK recommendation)

By reading in profile bar code nos. 11 and 12 (Section 10.2 Default setting), you can
define the above default settings temporarily with a different parameter set to allow
the PC to communicate with the CLV.
8. 5. 2 Connecting the functional interfaces
Sensor 1 switching input
In order to trigger a reading process, the CLV requires a suitable clock pulse in
Reading mode that signals the presence of a conveyor object in the reading field.
The clock pulse generates the reading interval (time window for evaluation) internally
in the CLV. In the default setting, the reading pulse is supplied by means of internal,
continuous reflector polling (see Section 9.2).
10
If an external sensor (e.g. photoelectric switch, switch) is to notify the CLV of the
presence of a conveyor object, the following steps must be performed:
Ø Connect the sensor to the CLV as shown in Fig. 5

Notes:
1. In order to replace the match code taught in in this way with a different match
code, you can repeat steps 3 to 6 without having to switch off the CLV.
2. If match code 1 is set using the teach-in method, it must not be modified with the
user interface (or command strings) until the CLV is switched off again. The
methods used to set the match code cannot be mixed. This does not affect
match code 2.
Result 1 to Result 3 switching outputs
The three outputs (Fig. 7) can each be assigned different result functions. When the
associated result occurs, the corresponding output becomes live for the selected

CAUTION
The two fastening threads (2, Fig. 1) on the bottom, narrow side of the housing are
used to secure the CLV. The thread dimensions are shown in Section18. Dimensioneddiagrams.
Risk of damage to the housing
The max. depth of engagement of the two M 4 tapped blind holes is 6 mm from
the housing surface. Do not exceed this depth.
Mounting accessories
The CLV can be easily secured to the base to suit the relevant application using one
of the two optional mounting brackets (Fig. 8). This facilitates precise adjustment in
two planes. The dimensions of these brackets are shown in Section 18.Dimensioned drawings. The elongated holes in the brackets allow the CLV to be
adjusted with a freedom of rotation of approx. ± 15°.

Aligning the CLV with the bar code
The alignment between the CLV and line or raster scanner depends on the
application. The basic alignment between the two scanning methods and the
conveyor object is shown in Fig. 9.
Fig. 9. Scanning method alignment relative to the bar code and conveyor direction
Reading angle and distance
When mounting the device, ensure that all of the possible reading angles at which the
bar code can be positioned relative to the scan line are taken into account. Fig. 10
shows this using a line scanner as an example. The reading window and code should
be almost parallel, whereby total surface reflection (see below) should be avoided.

Table 10
When selecting the mounting location for the device, the limit values of the reading
range for the selected bar code resolution and the useful aperture angle (max. 60°
with front light emission) must be taken into account. See also Section 16. Reading
field diagrams.

Avoiding surface reflection
If the reading beam strikes the surface of the bar code vertically, reflection
interference may be caused when the returned light is received.
Ø Mount the CLV with front light emission (a) in such a way that the scan line(s) strike
the bar code at an angle less than approx. 15° from the vertical reference (Fig. 11).
Ø The CLV with lateral light emission (b) must be mounted flush so that the scan line
is emitted at an angle less than 105° relative to the housing.

9. 2 Mounting the polling reflector
In order to generate the reading pulse automatically using internal reflector polling
(default setting), one of the two polling reflectors supplied (special bar code) must
be mounted opposite the CLV behind the conveyor section.
Ø Note the maximum ranges of the two reflectors (Fig. 13)
Ø Mount the polling reflector (self-adhesive) opposite the CLV (in the alignment line)
in such a way that the CLV can view the reflector freely in the gaps between the
conveyor objects and can scan it reliably (center of scan line).
The scan line of the CLV should scan the code lines of the polling reflector
vertically.
8 008 224/I982/08-00
Ø Check the polling reflector installation for 100% read quality using the
Percentage Evaluation mode in the T
ERMINAL option of the user interface (see
Section 10.6). The CLV outputs the code content of the polling reflector and
signals REPO as the code type.
Function of reflector polling
In Reflector Polling pulse mode, the CLV activates the laser diode with every 20th
scan and checks whether it detects the reflector:
- if the reflector is still detected, the CLV repeates the procedure after the 20th
• Reading distances (REPO)
Other distances must be respected
for CLV 412 and CLV 414. Only blue
REPO is allowed.
• Reading distances (REPO) CLV 412:150 ... 350 mm
• Reading distances (REPO) CLV 414:230 ... 650 mm

Distance:
40 ... 500 mm
- the CLV starts the reading interval when the reflector is concealed by a conveyor
object in the reading field. The interval ends when the CLV detects the reflector
again. It then repeats the procedure above.
Notes:
This clock mode (max. delay approx. 100 ms at a scan rate of 200 Hz) is only
suitable for applications that are not critical with respect to time.
When the CLV is switched on, it must be able to detect the polling reflector. The first
reading interval can only start if this is the case.
In Reading mode, the CLV does not output the content of the polling reflector.
9. 3 Mounting the external reading pulse sensor (alternative)
If an external sensor (e.g. photoelectric switch) is used to generate the reading
pulse, it must be mounted on the CLV in a suitable manner. Ensure that objects of
different size carrying bar codes trigger the internal reading pulse in such a way that
sufficient time is provided to read the code. Examples of the CLV with line scanner
are provided in Fig. 14.

switched on for the first time after delivery is shown in Table 11.
The tried-and-tested default parameters have been selected so that CLV can be
used directly in many applications without requiring modification.
The CLV must not be connected with the PC (offline mode). The default setting
values are stored permanently in the user interface and on the CLV. The parameter
values are displayed in the menu options of the individual configuration cards. You
can print out the entire default settings by clicking the icon.
Note:
When you make changes to the default settings, we recommend that you save them
as a different configuration file (*.scl) on the PC using the S
AVEAS option in the
program.
Temporary host interface defaults
In order to allow you to access the CLV with the PC at any time, you can set the
host interface temporarily to the default setting (9600 bits/s, 8 data bits/1 stop
bit, no parity) using the profile bar codes:
Ø Present profile bar code no. 11 to the CLV in Reading mode and supply
an appropriate clock pulse to the device.
The CLV resets the host interface to the default values and confirms this with
an acoustic signal from the beeper. It then resumes Reading mode
immediately
Ø To restore the previous host interface configuration on the CLV, present
profile bar code no. 12 to the CLV.
The CLV confirms that the values have been reset with an acoustic signal and
resumes Reading mode immediately.

IMPORTANT
Alternative:
Ø Switch the CLV off and on again to return to the original configuration
10. 3 Profile programming
Profile programming uses special bar codes to change the CLV parameters directly
without having to connect the PC with user interface. The profile bar codes are
simply presented to the CLV. The device then transfers the coded parameter values
to the current parameter set and stores them permanently. The changes remain valid
after the programming procedure has been completed and affect the further reading
procedure. The CLV waits 10 s after each profile bar code. If no more profile bar
codes are presented, it resumes standard Reading mode and confirms with two
consecutive acoustic signals.
Since the CLV overwrites important parameter values (e.g. those generated with
AutoSetup) without requiring confirmation, we recommend that you upload the valid
parameter set to the PC and store it as a configuration file (*.scl) with the S
option in the user menu before you change the parameter settings.
You can program the CLV at any time in Reading mode. Alternatively, you can present
one or more profile bar codes to the CLV for reading within 5 seconds after the
device has been switched on and the self-test has been completed (free-running).
The CLV does not output any reading results during profile programming and does
not respond to an external reading pulse.
A total of 12 selected profile bar codes are provided on the „Configuration Profiles
for CLV 41x Bar Code Scanner“ card to make important changes (from the default
settings or the application-specific parameter set respectively). By folding the
individual segments of the card, you can ensure that the CLV only reads the
required profile bar code. The function of the profile bar codes is explained in
Table12.
If you cannot access the host interface of the CLV from the “CLV Setup” user
interface (e.g. baud rate or data format not in line with default settings), the profile
bar code no. 11 can be used temporarily to set the CLV to the default settings
(host interface). To reset the system, use profile bar code no. 12 or switch off CLV.

Printing out
profile bar codes
Table 13
Note:
When changing the reading pulse type, we recommend that you present the
corresponding profile bar code (3 LT...) last so that reading of further profile bar
codes in free-running mode is not interrupted.
Printing out profile bar codes via the user interface
You can print out the profile bar codes offline (CLV not connected to PC), for
example, using the modified values in the configuration cards. One or more profile
bar codes are printed out on a page, depending on the number of changes made to
the default settings. You can set the size, position and number of codes printed out
on the page as required. Longer profile bar codes must be printed out in landscape
format (using the printer configuration window).
Ø Procedure for printing out profile bar codes
StepAction
1Start the CLV Setup program on the PC
2Open the stored configuraiton file (*.scl) for the CLV
3Change the relevant parameters in the configuration cards
4Define the print conditions using the C
in the PROFILES menu or accept the defaults
5Print out the profiles using the PRINT PROFILES menu option in the
PROFILES menu
6Save the modified parameter set to a new configuration file (*new.scl)
The AutoSetup function allows you to set the application-specific parameters
automatically to read
• a bar code (from a code type with a fixed code length)
• at a fixed reading distance.
For this purpose, the PC with the user interface must not be connected .
During AutoSetup, the CLV automatically determines the code type, code length and
the optimum scanning rate in free-running mode for the bar code presented at the
maximum reading distance. All other code types are disabled for furtherevaluation. The CLV writes the parameter values to the parameter set directly and
stores it permanently (EEPROM).
Since the CLV overwrites important code configuration parameters without requiring
confirmation from the user, we recommend that you upload the valid CLV parameter
set to the PC and store it as a configuration file (*.scl) using the S
AVEAS menu option
in the user interface before you change the CLV parameters.
AutoSetup can be started at any time in Reading mode by presenting profile bar
code no. 12 and triggering the corresponding reading pulse. Alternatively, the CLV
can read profile bar code no. 12 in free-running mode directly after the device has
been switched and within the wait time of 5 seconds after the self-test has been
completed.
The CLV does not output any reading results during teach-in mode and does not
respond to an external reading pulse.
Note:
The CLV does not enter any real values for the Minimum Distance and Minimum Bar
Width parameters, since it cannot determine absolute dimensions. When you upload
the parameter set from the CLV to the PC, therefore, the values in the R
CONFIGURATION card do not correspond to the actual values.
AutoSetup can also be called under the T

10. 5 Parametrization with the CLV Setup software
10. 5. 1 Installing the user and parametrization software
In order to switch between operating modes and set the parameters manually, you
need the Windows-based CLV Setup software supplied with the device. The program runs on Windows 3.11™, Windows 95™ and Windows NT™. The user interface
can also be used when it is not connected to the CLV to configure applicationspecific parameter sets (offline mode). The CLV must be connected to the PC,
however, to transfer modified parameter values (download) directly (online mode).
8 008 224/I982/08-00
Ø Copy the CLV Setup and CLV Setup Help software to the hard disk of your PC and
install the programs.
The user interface (Fig. 16) is largely self-explanatory. The introduction and online
CLV Setup Help function demonstrate how easy it is to use.
The data displayed on the configuration cards is first stored temporarily to the main
memory of the PC. You can save this data permanently to a configuration file (*.scl)
on the PC using the S
From this point onwards, it is assumed that the user has started the program
and that the CLV is connected to the PC. Any existing data connections to the
host must be disconnected.
IMPORTANT

Displaying the default settings in the configuration cards
The program then loads the internal description of the CLV as well as the default
parameter values and displays them on the tabs. Finally, CLV Setup uploads the
current parameter set from the RAM of the CLV and displays the values on the tabs
instead of the default values.
You can edit the current parameter set on the tabs. The default values are displayed when
the device is used for the first time.
Troubleshooting
If the CLV-setup screen shows “no connection” in the lower right menu bar, the
program couldn’t connect to the CLV. There may be two reasons, either the CLV is
not connected or the communication parameters of CLV and PC do not match. The
CLV setup program stores the type of CLV which was successfully contacted before
in the list field “appliance” of the symbol bar. When calling the CLV setup program
for the first time the CLV type is by default “CLV 41x”. For this CLV type, the
program loads the internal appliance description and the default parameters from its
data base and displays the values in the corresponding tabs.

Displaying the active CLV parameter set
To view the active CLV parameter set and change it via the configuration cards, you
must first either
Ø transfer (upload) it from the CLV to the PC or
Ø open the active configuration file (*.scl) on the PC.

10. 5. 2 Setting the parameters via the configuration cards
After the start of the CLV setup program, the cards display the parameter values of the
current CLV.
Upload
The ”CLV Setup” loads the current parameter settings of the CLV to the database
and displays the values of the configuration cards. During the data transfer, the
„Device Ready“ LED is off.
If the ”CLV Setup” software is unable to read the loaded parameters during the
upload, a warning is issued. Unknown parameters can be edited in the “EXTRAS”
tab, following the general rules for command strings. When saving the parameter
set, these parameters are taken into account.
Download
The changes made to the configuration cards do not take effect until they have
been transfered to the CLV. When you download the file, the CLV asks you whether
you want to store the new parameter set temporarily or permanently.
TIP:
Quick help
TIP:
If the current parameter set has been changed and transferred to the CLV
permanently, we recommend that you back up this parameter set by saving it as a
configuration file (*new.scl) on the PC using the S
AVE AS command.
Online Help function
The parametrization procedure is supported by the online CLV Setup Help function.
The online help runs on an HTML browser (e.g. Netscape™ or Internet Explorer™).
The PC searches for this browser and opens it automatically. If it cannot be found, a
window is displayed asking you to specify the directory in which the browser is
stored on the hard disk.
You can call context-sensitive help on the parameter you are currently processing by
pressing F1. You can choose the configuration card on which you want help in the
top, horizontal frame. The associated parameters are then displayed in the left-hand
frame. When you click one of these parameters, a detailed description is displayed
in the right-hand frame. To display the help overview, choose the C
ONTENTS command
in the HELP menu.
To prevent several browser windows from being opened, we recommend that you
use the ALT + TAB keys in Windows to switch quickly between the CLV Setup and
CLV Setup Help applications.
You can print out and archive new parameter sets by clicking the
icon.
The manual entitled Menu-Driven Parametrization of the CLV Bar Code Scanner
explains the parameters and their functions and can be used as a reference for
more complex applications.

*) permanently?:
The CLV saves the modified parameter set in the main memory (RAM) to the EEprom.
These values remain stored when you switch off the device. The next time you switch on the CLV, these
values are loaded to the main memory of the CLV and are used as the active parameter set.
temporary?:
The CLV only transfers the modified parameter set to the main memory (RAM). These values are lost
when you switch off the device. The parameter set last stored in the EEprom is loaded to the main
memory and used as the active parameter set the next time you switch on the CLV.
Table 17
Function of the configuration cards
Reading Configuration
This card is used to change the scanning frequency, reading distance, resolution,
start/stop ratio and the evaluation range of the scan line.
Device Configuration
This card is used to change the device number, reading pulse, output time of the
reading result and the separator in the data output string as well as the functional
assignment of the three switching outputs Result 1...3 and the beeper.
Code Configuration
This card is used to activate/deactivate the individual code types that are to be
evaluated and to change the number of identical reads as well as the minimum and
maximum number of bar codes to be read/output.
We recommend that you only activate those codes that are actually relevant in order
to enhance the reading reliability with fast applications.
This card is used to change the protocol, start and stop characters, data format and
the transmission rate.
Data Strings
This card is used to change the data output format of the host interface. ASCII
characters and reading diagnosis data can be transferred to the host in the header,
separator and terminator (default setting: no characters). The output format for no
reads and the content of the error string can be modified. The test string function
can also be activated here. If more than one bar code is to be read during each
reading pulse, you can specify the output sequence and sort criteria.
Extras
If required, these tabs are used to treat parameters, which are unknown to the CLV
setup program after an upload from the CLV.
Note:
The program “CLV-Setup Help” describes the functionality and the allowed values of
the parameters. Call “CLV-Setup Help” by pressing “F1”.
The CLV features the following operating modes/functions:
• Reading mode
• Percentage evaluation
• Profile programming
• AutoSetup
• Parametrization

This temporary operating mode is only accessible via the user interface and is used
to assess the quality of the reading function. In this case, the CLV evaluates 100
scans statistically (independent of the set pulse type) in free-running mode. It
outputs the reading result continuously. You can view the results with the user
interface.

11. 1 Transferring the application-specific parameter set
If you have to replace a CLV on site and therefore transfer the active parameter set
to the new device, there are two methods of doing so. The parameter set can only
be transferred to a device of the same type.
Transferring the parameter set locally using profile bar codes
Prerequisite:the active parameter set is available in archived form as printed
profile bar codes.
It is not necessary to connect the PC to the CLV Setup program.
StepAction
1Disconnect the power supply to the AMV/AMS Connection Module
2Disconnect the CLV connector from the AMV/AMS Connection Module.
Remove the CLV from the bracket on the reading station.
Mark the position and alignment on the bracket/station.
3Mount the new CLV and connect it to the AMV/AMS
4Reconnect the power supply to the AMV/AMS Connection Module
5Present the first archived profile bar code to the CLV within
acoustic signal.
The CLV confirms the good read with an acoustic signal and waits 10 s for the
next profile bar code.
6Present all of the other profile bar codes consecutively in the order in which they
were printed.
7Finally, allow the last 10 s wait time to expire.
The CLV then outputs two consecutive acoustic signals and switches to Reading
mode. The Device Ready LED lights up.
The new CLV can now be used with the transferred parameter set.

Notes:
The procedure for printing out the profile bar codes is described in Table 14 in
Section 10.3 Profile programming.
If none of the profile bar codes of the parameter set for the device to be replaced
has been printed out and if the configuration file (*.scl) has not been saved on the
PC, you can try, depending on the reason why the device is to be replaced, to
upload the parameter set from the CLV to be replaced to the user interface and then
download it to the new CLV.
30
Ø Transferring the parameter set by means of a download
If the profile bar codes of the parameter set have not been printed out but a
configuration file (*.scl) does exist, you must connect the PC with the CLV Setup
software to the new CLV (see Section 8.4 Connecting the PC to the CLV).
In the following section, it is assumed that the new CLV is using the default settings.
1Replace the CLV as described in steps 1 to 3 in Table 18
2Disconnect any data connections to the host
3Connect an RS 232 data connection cable to the AMV/AMS and PC
4Reconnect the power supply to the AMV/AMS Connection Module
5Start the CLV Setup program on the PC
6If you cannot access the new CLV (red display NO CONNECT! at bottom right)
click the (upload) icon (CLV transfers its parameter set to the PC)
7Open the configuration file (*.scl) stored for the old CLV
8Click the (Download) icon (new CLV receives the application-specific parameter set)
9Choose the Permanently storage option for the CLV in the dialog window
10Close the configuration file (*.scl) again.

11. 2 Disassembly and environmentally friendly disposal of the CLV
If the CLV is to be disposed of (after it has reached the end of its service life), the
national waste disposal regulations applicable at the time at which the device is
taken out of service must be observed.
• The housing of the CLV (chassis and cover) is made of die-cast zinc and can be
submitted for recycling after the glass plate of the reading window has been
removed.
• The electronic modules and connection cables can be easily removed. However,
they must not be disposed of as domestic waste but rather sent to a suitable
plant for treatment as problem waste.

UTO SETUP
13. Maintenance
SICK service and repair
If correct operation of the CLV cannot be restored using the troubleshooting
measures provided above, the device may be defective. The CLV does not contain
any system components that can be repaired by the user.
Please contact the SICK Service department:
• Through your local SICK subsidiary or branch office; the address and telephone
number are provided in the frame on the rear of these Operating Instructions
Please contact the SICK Service department first before sending in the device!
The CLV does not require maintenance. The self-monitoring functions enable the
device to operate fault-free at the reading station. The CLV indicates errors with the
status ST in the data output string (if enabled). If operated under extreme conditions
(excessive dust, abrasion, humidity), we recommended that you clean the reading
window at regular intervals using a mild, water-soluble detergent to maintain the
reading performance.
When cleaning the reading window, avoid any scratching or scouring movements
on the surface of the glass.
The protection provided may be impaired, in case that the CLV is not used in the
way described in this operating instructions.
In order to prevent damage to health, please observe the following at all times:
Ø Observe the most recent laser protections specifications to DIN EN 60825-1
Ø Do not stare into the laser beam (comparable with sunlight)
Ø Do not direct the laser beam at the eyes of other persons
Ø When installing the device, check for possible causes of reflection of the laser
beam during operation, e.g. reflective surfaces
Ø Use the plug for disconnecting the CLV! The plug must be easily accessible.

Internal safety circuits
The CLV is equipped with monitoring circuits that deactivate the laser diode in the
event of irregularities in the laser beam generation. Activation and deactivation of the
laser diode is controlled by the reading pulse. In Percentage Evaluation and Freerunning modes, the laser diode is activated constantly. With Reflector polling, it is
activated with every 20th scan.
Warning labels
You can attach the additional laser warning labels (German/US English or French/US
English) over the GB English/US English sticker on the CLV if required.
If the CLV is installed in a machine/panel with the result that the warnings on
the device are concealed, additional warning labels (not included in the
scope of delivery) must be attached to the machine near the laser emission
aperture.
