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.

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 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. 2-1: Laser warning labels found on the CLV
Note The 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
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.

Further processing 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.

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.

4.2.7 Distance between the CLV and the bar code

Basic alignment of the scan line to the bar code
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.

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: 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.

Installation
Angular alignment of the CLV
Optimum alignment of the CLV is achieved when the scan line travels over the bar code lines almost at a right angle (90
°) (Fig. 4-4). All possible reading angles that can occur between
the scan line and the bar code must be taken into consideration (Fig. 4-6 and Table 4-1).

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.

4.2.8 Count direction of the code position CP

Explanation The 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. 4-4 shows 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.

4.3 Installing and adjusting the device

4.3.1 Installing the CLV

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.

4.3.2 Adjusting 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.

Performing fine adjustment
7. Align the CLV in such a way that the angle between the scan line and the bars on the bar code CLV is almost 90
°.
8. To prevent interfering reflections, tilt the CLV away from the vertical axis so that the light strikes the bar code at an angle of approx. 105
° (line scanner) (Fig. 4-7, Page 4-5).
9. If necessary, position the center of the scan line exactly on the bar code (see
Chapter 4.3.3 Auxiliary functions for adjustment, Page 4-8).
10. Move objects carrying bar codes into the CLV reading field manually under realistic conditions and check the reading result. If the objects are aligned randomly, or if the bar code is located at different positions (angles), ensure that the limit values of the permissible reading angles are not exceeded.
11. Adjust the CLV in such a way that the good read rate is between 70 and 100 %.
12. Tighten the screws on the CLV.
The CLV is aligned with the bar code.

4.3.3 Auxiliary functions for adjustment

Adjusting mode
The "adjusting mode" helps you to position the center of the scan line on the object. To do so, the CLV masks out one half of the scan line from the center (code position CP CP
= 100). Fig. 4-9 shows the resulting appearance of the scan line with the line scanner.

Installation
1. Activate the operating mode as described in Chapter 6.5.3 Adjusting mode, Page 6-18.
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.

4.4 Installing external components

4.4.1 Installing the CDB 420 or CDM 420 connection module

1. Install the CDB 420 or CDM 420 connection module near the CLV. The distance between the CDB 420 or CDM 420 and CLV must not exceed 10 m (32.8 ft).
2. Install the CDB 420 or CDM 420 in such a way that the device can be accessed when opened. The terminal interface of the CLV is accessed via the internal "Aux" connector.
Detailed information on the installation and electrical installation procedures is provided in the “CDB 420 Connection Module“ Operating Instructions (order no.
German/English version) respectively in the “CDM 420 Connection Module“ Operating Instructions (order no.
8 010 004, German/English version).

4.4.2 Installing the external reading pulse sensor

If the CLV is triggered by an external reading pulse sensor, the sensor must be mounted in 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
Explanation When 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.
Note This 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
power supply to the module (see
Chapter 5.5.3 Connecting the power supply,

To prevent interference, do not lay the cable parallel with power supply and motor
cables over long distances, e. g. in cable ducts.
max. 38,400 bd max. 1,200 m (3,937 ft)
max. 57,600 bd max. 500 m (1,640 ft)

5.4.2 Power 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.
Note The CLV 42x is UL certificated when a class 2 power supply according to UL 1310 is used.
Power-up delay
The selected device number (default setting: 1) affects the power-up delay of the device. This is useful if a large number of CLVs (e. g. in the SICK CAN Scanner Network) are supplied from one power source.
Device number GN Power-up delay Device number GN Power-up delay

6.3 Quick start

A PC need not be connected when the CLV is operated with the factory default settings. Code 39, 2/5 Interleaved, and Code 128 are the default code types enabled (free code lenght, 2/5 Interleaved: interval 4 to 50 characters).

6.3.1 Starting up the line/raster scanner with the factory default settings

1. Connect the CLV to the SICK CDB 420 or CDM 420 connection module.
2. Connect the reading pulse sensor (e.g. photoelectric switch, switch) to the "Sensor 1" switching input of the CLV via the CDB 420 or CDM 420. See
the "Sensor 1" switching input, Page 5-8.
3. Switch on the power supply to the CDB 420 or CDM 420. 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. The "Result 1" ("Device Ready") output switches.
4. Start the reading pulse: block the light path of the photoelectric switch or close the switch. The "Laser On" LED lights up. The CLV switches the laser diode on and the red scan line appears.
5. Present the bar code pattern from Fig. 6-1 to the CLV at the reading distance specified in Table 6-2.
6. Align the bar code in such a way that the red scan line is almost at a 90° angle to the bars.
7. End the reading pulse: unblock the light path of the photoelectric switch or open the switch. The "Laser On" LED is extinguished. The CLV switches off the laser diode. The CLV confirms that the bar code was read successfully by outputting a tone via the beeper. The "Result" LED lights up for duration of 100 ms. The "Result 2" (Good read) output switches for the duration of 100
ms.
The CLV can now be operated with the factory default settings.
The device can be switched off without the configuration data being lost as no changes have been made to the parameter set.

6.4 Configuration (parameterizing)

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)), see Chapter 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), see Chapter 10.6 Configuring the CLV with command strings, Page 10-22.
In Parameter mode, the CLV only outputs a reading result with AutoSetup.

6.4.1 Configuring 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 ("Download parameters of this view") will be (RAM).

6.4.4 Configuring 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

Operation
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.
Explanation AutoSetup 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)

Operating Instructions Chapter 6
CLV 42x bar code scanner
Operation
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.
Note The 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
and 100 %.

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.

6.5.4 Show CP-limits

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, DEVICE FUNCTIONS (interactively).
The CLV masks the scan line alternately from the set value for CP for CP

6.5.8 Auxiliary 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.

6.5.9 Self-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.

7 Maintenance

7.1 Cleaning during operation

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.
Use a soft, lint-free cloth.
If necessary, clean the LEDs on the rear of the device.

8.2 Monitoring 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 "Sensor Input" and "Serial Interface". In this case, the CLV outputs the message: "
