2.3General safety instructions and protection measures
Ø Always read the general safety instructions carefully and observe them at all times. This
also applies to the warnings provided for the individual activities described in this
document.
Depending on the type of device, the AMS 60 Connection Module (accessory) for the CLV
is connected to a mains voltage of 230 V AC 50 Hz or 115 V AC 50/60 Hz.
WARNING
WARNING
Ø When working with electrical equipment, always follow the relevant safety specifications.
Laser beam can cause blindness!
The CLV uses a class 2 red-light laser. Looking directly at the laser beam can seriously damage your eyesight.
Ø As with sunlight, never look directly into the laser beam.
Ø Do not direct the laser beam at other persons.
Ø When mounting and aligning the CLV, avoid reflections caused by reflective surfaces.
Ø Do not open the housing.
Opening the housing does not deactivate the laser diode.
Ø Observe the most recent laser specifications (DIN EN 60825-1, latest version).
Laser power
The laser operates at a wavelength of λ =650 nm (visible red light). The power output at
the reading window is max. 2.8 mW.
The emitted radiation is not dangerous to human skin.
Laser warnings
The laser warning labels for Europe (Fig. 2-1) are attached at the following positions on
the CLV:
• The laser warning symbol on line scanners is positioned beside the reading window on
the front side of the device. The GB/US laser warning is located on the side containing
the electrical connections.
• The laser warning symbol on line scanners with oscillating mirror is located above the
reading window, on the cover of the mirror. The GB/US laser warning is located on the
side containing the electrical connections.
The device is supplied with an additional set of laser warning labels in German/US English
and French/US English. If necessary, these can be used to cover the GB/US warnings.
If the CLV is installed in a machine/panel with the result that the laser warning
plates are no longer visible, additional warnings (not included in the scope of delivery) must be provided on the machine beside the emergence aperture of the laser
beam.
Internal protective circuits
The CLV is equipped with monitoring circuits that deactivate the laser diode in the event of
a malfunction. Activation and deactivation of the laser diode is controlled by the reading
pulse trigger.
A safety circuit (timer) automatically deactivates the laser diode in Reading mode (“Sensor
input” and “Serial interface” trigger mode) if the reading interval has not ended after 10
minutes. However, it does not end the reading interval. In this case, the CLV outputs the
message:
“Laser safety timeout”
on the terminal interface. The reading interval must be terminated by resetting the trigger
signal. The laser diode is activated again by the next reading trigger.
In the Percentage Evaluation mode, Adjusting mode and Show CP-limits as well as in
the “free-running“ reading mode the laser diode is constantly activated.
2.4Quick stop and quick restart
2.4.1Stopping the CLV
Ø Switch off the power supply.
This can result in loss of the following (at the most):
• the application-specific parameter set, if it was stored temporarily in the CLV
• the last reading result
• daily operating data
(operating hours counter, trigger count, good read count, maximum duration trigger,
minimum duration trigger, average identification quality)
2.4.2Restarting the CLV
Ø Switch on the power supply.
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 and, therefore, does not represent any problems for paint
sprayers in paint shops, for example.
• the line scanner has a typical power consumption of 9 W and max. 16 W
• the line scanner with oscillating mirror has a typical power consumption of 9 W and max.
18 W
• the line scanner equipped with an integrated heater has a typical power consumption of
75 W and max. 90 W
• the line scanner with oscillating mirror equipped with an integrated heater has a typical
power consumption of 75 W and max. 100 W
The values are given for devices with disconnected switching outputs.
2.5.2Disposal after removal from service

The CLV is equipped with two decoders:
• The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding
bar codes with small code height, bar codes that are dirty or damaged, as well as bar
codes that are tilted excessively (azimuth angle)
• The tried-and-tested standard decoder of the CLV series
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 the 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. In the
default configuration, this trigger is supplied by an external reading pulse sensor. Alternative trigger sources include free-running mode or a command via the host interface (for
more complex applications: OTC triggers).
The current operating status is indicated by four LEDs.
If the trigger is supplied externally, the “Sensor” switching input instructs the CLV to start
the reading process. The five switching inputs “IN 0 ... IN 4” switch the focus position in
response to certain events, as an alternative to the autofocus function. The inputs “IN 3”
and “IN 4” can also be assigned special functions. The four switching outputs “Result 1
... Result 4” can be assigned different functions for displaying the result status and also
control external devices, such as a PLC.
The CLV is operated and configured via the terminal interface (auxiliary interface) using
the CLV Setup software or via the host interface/terminal interface using command
strings.
System, warning, and error messages help you configure the device and locate the source
of errors during startup and reading mode.
3.2.1Autofocus function
The autofocus function enables the CLV to detect the distance of an object during the
reading process, without the need for external sensors, and then adjust the focus position
automatically to the reading plane of the bar code. In order to do so, the CLV measures
the object distance each time in its visible range in front of the reading window and
internally creates a distance profile. Following this, it positions the focus on the object.
3 operating modes are provided for various applications:
• Minimum distance: the CLV focuses on the minimum distance in the distance profile
and ignores the background in the visible range. Application: with unobstructed view of
the object without any surrounding objects protruding into the reading plane.
• Differential background: the distance profile of the visible range background is pro-
grammed (teach-in) in the CLV without any objects present. During the reading process,
the CLV then focuses on the object which it recognizes by comparing it to the distance
profile of the background. Application: with unobstructed view of the object restricted by
other objects that protrude into the reading plane.
• Differential background and tracking: if several objects with different distances are
positioned in the reading field at the same time (distance conflict), the CLV focuses on
the object that is nearest to but has not exceed its internal focus switchover point.
Application: in OTS operation (applications with tracking by the Omni Tracking Controller
OTC 400)
The distance profile of the background can also be displayed. The visible range is defined
by the autofocus range, the aperture angle, and (in the case of line scanners with oscillating mirror) also by the angle of deflection. The park setting of the focus position, from
which the device focuses for each read, can be specified in addition to a time or positionrelated delay (timeout or hysteresis). If necessary, an offset can be defined for the focus
position to be set by the measurement. The depth of field, which radiates in the direction
of the scan line and is caused by the V-principle of the beam deflection, is optimized as a
result (Fig. 3-3).

Depth of field (DOF)
Fig.3-3: Optimizing the depth of field for the object
As an alternative to the autofocus function, the CLV can switch its focus position in response to certain events and thus dynamically cover a large reading range. A maximum of
eight reading ranges can be defined as distance configurations for this purpose and
approached consecutively in reading mode (Fig. 3-4).

The switchover takes place in response to changes in the object distance (with reads from
above: object height detection). The trigger source for the switchover is a signal combination at the switching inputs “IN 0 ... IN 4”, a command on the host interface or the integrated timer (e.g. for search mode). Additional in the case of the line scanner with
oscillating mirror also the oscillating mirror reversal points. The distance configurations are
assigned to the swichover sequence by means of a programmable assignment table. The
distance measurement of the autofocus function can be used to define the distance
configurations.

3.2.3Scan procedure variants
Line scanner (standard device)
Generates a scan line; due to the V-principle of the beam generation, the reading field
height (the useful length of the scan line for evaluation purposes) is dependent on the
reading distance.
Line scanner with oscillating mirror
The oscillating mirror also deflects the scan line perpendicularly to the scan direction at
both sides around the neutral position with a low oscillating frequency. As a result, the CLV
can also scan larger areas for bar codes. Due to the V-principle of beam generation, the
reading field height is dependent on the reading distance.
In addition to parking and simple deflection with maximum amplitude, optimized oscillating
mirror functions are also available:
• Oscillating with variable deflection amplitude per distance configuration
• One-shot: one-off, defined deflection per reading pulse (forward and return phase).
The CLV can be permanently equipped with a heater for applications involving temperatures up to max. -35 °C (e.g. in a freezer). The design, technical data, and power-up
behavior of the CLV are described in Section 10.4, Page 10-20.
External parameter memory
The external parameter memory is located in a connector cover which, when mounted,
covers the two electrical terminals on the CLV (IP 65). The parameter memory saves you
time when a CLV is replaced locally by providing a copy of the current parameter set. In
other words, you do not have to configure the new device.
For information on applications and operating procedures, see Section 10.3, Page 10-16.
3.3Indicators and control elements
3.3.1Control 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 parameter options allow you to adapt the device to a wide range of
applications.
The following can be defined:
• The configuration of the code types
• The read, evaluation, and output properties
• 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
Section 10.6, Page 10-23 describes the procedure for installing the CLV-Setup program
and explains how to use it. The parametrization (configuration) procedure is explained in
Section 6.4, Page 6-5.
3.3.2Function of the LEDs
Four LEDs indicate the operating status, activity of the laser diode, reading result status,
and data transfer on the host interface. The LEDs are located on the rear of the device
(Fig. 3-5).
If the optional external parameter memory is connected, the LEDs also indicate whether
the memory was successfully accessed.
The meaning of the LEDs in the various operating modes/functions is shown in Table 3-2
and Table 3-3.

- or -
Alternatively, if the bracket is supplied by the user
- Stable mounting device that allows the alignment of the CLV to be varied in the x and y
axes. The weight of the CLV (line scanner) is 1.5 kg and 2.2 kg as a line scanner with
oscillating mirror
- 2 screws M6 for the CLV. The screw length depends on the wall thickness of the
bracket used. Depth of engagement in CLV max. 7 mm from housing surface
• AMV/S 60 Connection Module (not included in the scope of supply of the CLV)
• Reading pulse sensor for external reading pulse trigger, e.g. photoelectric reflex switch/
photoelectric proximity switch (not included in the scope of supply of the CLV)
• Option with event-controlled dynamic focus control: sensors for detecting the object
distance, e.g. photoelectric reflex switches/photoelectric proximity switches (not
included in the scope of supply of the CLV)
4.2.3Required auxiliary parts
• 2 screws M6 for securing the SICK mounting bracket to the base. The screw length
depends on the wall thickness of the base.
If necessary, replace the GB/US laser warning label with the required language (Fig. 4-1).

See also Section 2.3, Page 2-2.
Laser warnings:
Fig.4-1: Line scanner: replacing the laser warning labels
4.2.5Selecting the mounting location
When you select the mounting location, the distance between the CLV and the host and
between the CLV and the bar code are extremely important.
Distance between the CLV and the host
The CLV can be mounted at a maximum distance of 1200 m from the host without a
connection to the SICK network or a bus. In practice, however, the distance depends on
the physical configuration of the host interface and the data transfer rate.
See Table 5-7, Page 5-8.
Distance between the host and the AMV/S 60 Connection Module
The AMV/S 60 Connection Module should not be located further than 10 m 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 secured in position using the two tapped blind holes (M6) above the electrial
connections. The position of these holes is shown in Fig. 4-2.
The dimensions of the CLV housing are shown in Figs. 9-1 to 9-3, Page 9-3 onwards.
The brackets are designed to support a variety of mounting positions and alignments in
two planes. Fig. 4-3 shows two mounting examples.
The elongated holes in the mounting bracket no. 2 013 824 and in the articulated bracket
no. 2 018 435 allow the CLV to be adjusted with a freedom of rotation of ±15°.

The dimensions of the mounting brackets are shown in Section 10.12, Page 10-45.
Depending on the application, the line scanner or line scanner with oscillating mirror
versions 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.
Line scanner

Reading distance from the 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 for various resolutions (module widths) in Sections 10.2.3, Page 10-3 and in
Section 10.2.4, Page 10-9.
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.

The useful aperture angle α is max. 56° for the line scanner and max. 50° for the line
scanner with oscillating mirror. 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.
The alignment of the CLV is optimum 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).

Avoiding surface reflection
If the light from the scan line strikes the surface of the bar code vertically, interference may
be caused by reflections when the returned light is received. To avoid surface reflection,
the CLV must be mounted in such a way that the emitted light is tilted slightly with respect
to the vertical axis (Fig. 4-7).

105°
(Side view)
In the case of the line scanner with oscillating mirror, the laser beam is emitted at an angle
of 105° with respect to the housing as it passes through the neutral position (CW=50)
while oscillating. The device can only be flush-mounted with the conveyor belt with limited
deflection ranges. Otherwise, the device must also be mounted at an angle of 15° to
ensure that the deflection ranges are symmetric.
Note
Explanation
In oscillating mode with variable amplitude, the scan line must always sweep the neutral
position (CW=50). This means that oscillation is not possible in the range 60 CW to 80
CW, for example, but is possible in the range 40 CW to 80 CW.
4.2.8Count direction of the code position CP and code angle CW
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:
• the position (CP value) of the center of the bar code within the scan line
• (scanning method using the oscillating mirror) also the angle of deflection of the scan
line (CW value) at which the center of the bar code is recorded
Fig. 4-8 shows the count direction of the code position and code angle. In the case of the
line scanner, the count direction of the code position is marked by a small triangle above
the reading window.
By determining this data, the device can separate identical bar codes (code type, code
length, and data content identical) and assign the bar code data in the reading result to its
position on the object.

4.3Mounting and adjusting the device
4.3.1Mounting the CLV
1. Prepare the base for mounting the bracket as described in Section 4.2.2, 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.
IM PORTANT
3. Align the CLV with the bar code (in accordance with the scanning method) in such a
way that
- with the line scanner the back of the device with the LEDs is almost parallel with the
bar code surface
- with the line scanner with oscillating mirror, the broad side wall (back of the oscillating
mirror) 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 it is relevant for the evaluation, note the count direction of the code position and
code angle (see Fig. 4-8, Page 4-6).
5. Mount the CLV bracket on the base.
Risk of damage to the housing!
The maximum depth of engagement of the two tapped blind holes M6 is 7 mm.
Longer screws will damage the housing.
Ø Use screws with the correct length.
6. Screw the screws M6 through the bracket into the tapped blind holes of the CLV.
The CLV can be adjusted in Percentage Evaluation mode. 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 and evaluates the reading
quality statistically. It then outputs the reading results every 2 s on the terminal interface.
The behavior of the “Read result” LED also indicates the reading quality. The LED does not
light up if the CLV cannot read the bar code (reading quality <30%). If the CLV is having
problems reading the bar code (reading quality 30% ... 90%), the LED blinks. The CLV is
aligned optimally when the LED lights up constantly (reading quality >90%). The scanning
frequency in the default setting is 800 Hz.
1. Connect the CLV to the AMV/S 60 Connection Module and switch on the power supply
(see Section 5.5.3, Page 5-13).
After it has started, the CLV confirms that the self-test was successfuly and switches
to Reading mode (Device Ready LED lights up).
2. Connect the PC to the terminal interface of CLV via the RS 232 line using the internal
9-pin “Service” connector of the AMV/S 60 (see Section 5.5.5, Page 5-15).
3. Start Windows and the CLV Setup program
(see Section 10.6.3, Page 10-25).
Choosing the standard decoder:
4. Choose the “CODECONFIGURATION” tab.
5. Click the “STA N D AR D ” option in the “DECODER” group.
6. Download the settings to the CLV by clicking on the toolbar.
The “DOWNLOAD PARAMETERS” dialog box is then displayed.
7.Confirm the dialog box by choosing “TEMPORARY”.
The CLV then operates with the standard decoder.
Activating Percentage Evaluation mode:
8. From the “VIEW” menu, choose “PERCENTAGEEVALUATION”.
The dialog box for entering the distance configuration appears.
9. Click the relevant distance configuration for the reading distance:
- with auto-focus mode the distance configuration no. 1
- with event-controlled dynamic focus control the distance configuration that matches
the reading distance of the object (default: no. 1, focus position F = 1,200 mm).
10. Confirm the dialog box with OK.
The Terminal Emulator is launched and displays the reading result continuously
(see Section 6.5.2, Page 6-22).
Monitor the reading quality (%) during each of the subsequent steps!
Line scanner with oscillating mirror:
In Percentage Evaluation mode, the CLV switches of oscillating mode (default setting:
oscillating) and positions the scan line at the angle 50 CW, corresponds to an angle of
emergence of 105°. The angle can not be changed.
4-8
Fine adjustment:
11. 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°. The oscillating mirror must be aligned in such a way that
the scan line is located at the center of the bar code, perpendicular to the bar code
lines, when it is in the neutral position (CW=50).
12. To avoid 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) (see Fig. 4-7, Page 4-5).
13. If necessary, position the scan line exactly at the direct center of the bar code.
See Section 4.3.3 below.
14. Move objects carrying bar codes into the CLV reading field manually under realistic
conditions and check the reading result. If the objects 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.
15. Adjust the CLV in such a way that the good read rate is between 70...100%.
With event-controlled dynamic focus control, for each defined reading range (distance
configuration), check the selected focus position and correct the parameter settings if
necessary (see Section 6.4.3, Page 6-9).
16. Tighten the screws on the CLV.
The CLV is aligned with the bar code.
4.3.3Adjusting 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=50 to
CP=100). This is irrespective of whether the CLV is operated in Autofocus mode or with
distance configurations for event-driven dynamic focus control.
Fig. 4-9 shows the resulting position of the scan line (line scanner).

1. Activate the operating mode as described in Section 6.5.3, Page 6-23.
2. Position the CLV in such a way that the center of the scan line, indicated by the end of
the 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.
1. Mount the AMV/S 60 Connection Module near the CLV.
The distance between the AMV/S 60 and CLV should not exceed max. 10 m.
2. Mount the AMV/S 60 in such a way that the device can be accesses when opened.
The terminal interface of the CLV is accessed via the internal “Service” connector.
Detailed information on the mounting and electrical installation procedures is provided in
the Operating Instructions for the “AMV/S 60 Connection Module” (order no. 8 008 296).
4.4.2Mounting 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” switching input is selected as the default trigger
source for this trigger type. The default debounce time of the input is 30 ms.
Fig. 4-10 shows two examples of where a photoelectric reflex switch can be mounted.
This depends on the distance a from the bar code to the front of the object. Depending on
the application, you may need to mount the sensor in such a way that bar codes on
objects of different sizes can be read completely during the reading interval.

2. Connect the reading pulse sensor to the “Sensor” switching input of the CLV via the
AMV/S 60 Connection Module (see Section 5.5.6, Page 5-16).
3. Connect the CLV to the AMV/S 60 Connection Module and switch on the power supply
to the module (see Section 5.5.3, Page 5-13).
After it has started, the CLV confirms that the self-test was successfuly and switches
to Reading mode (Device Ready LED lights up).
4. Connect the PC to the terminal interface of CLV via the RS 232 line using the internal
9-pin “Service” connector of the AMV/S 60 (see Section 5.5.5, Page 5-15).
5. Start Windows and the CLV Setup program
(see Section 10.6.3, Page 10-25).
6. From the “VIEW” menu, choose “READINGMODE”.
The Terminal Emulator is launched. The CLV is in Reading mode (default: SMART
decoder).
Monitor the reading result during each of the subsequent steps!
Line scanner with oscillating mirror:
In Reading mode, the CLV deflects the scan line (default setting) about the fixed
position CW=50 with a frequency of 1 Hz at a max. angle of ±20° (±40 CW).
50 CW corresponds to an angle of emergence of 105°.
7.Move objects with bar codes into the CLV reading field manually under realistic conditions and check whether the reading result and trigger pulse are correct.
8. Repeat the procedure with the conveyor switched on. Check whether the reading
procedure is synchronized with the objects.
Parameterizing an external sensor as a trigger source:
These settings are not required if the CLV is operated with the default configuration.
1. Choose the “DEVICECONFIGURATION” tab.
2. Click the “EDIT READING TRIGGER” button.
The “EDIT READING TRIGGER” dialog box is displayed.
3. Choose “SENSOR INPUT (ACTIV E HIGH)” and confirm your selection.
4. Download the settings to the CLV by clicking in the toolbar.
The “DOWNLOAD PARAMETERS” dialog box is then displayed
5. Confirm the dialog box by choosing “PERMANENT”.
The CLV operates with the “Sensor” switching input as an external trigger source. The
reading pulse starts when the power supply is connected.
4.4.3Mounting the sensors for detecting the object distance
If the dynamic focus control function of the CLV is triggered by external sensors, suitable
sensors must be mounted in the vicinity of the CLV. Fig. 4-11 shows an example of a read
operation from above. The sensors must be arranged in such a way that all of the
potential object heights are classified uniquely and overlapping reading ranges occur that
can be formed with the depths of field of the CLV. A maximum of five switching inputs are
available for this purpose. A max. of 32 switching states for 8 distance configurations
(reading ranges) can be implemented using the internal assignment table (combinations).
Photoelectric reflex switches, for example, can be used to detect the object distance. In the
default setting, all five switching inputs IN 0 ... IN 4 are selected for dynamic focus control.

suitable focus positions for overlapping reading ranges.
2. Mount distance sensors (e.g. photoelectric reflex switches) one above the other in a
row at the mounting location to measure the object distance (see also assignmenttable 5-20, Page 5-18). It is advisable to mount these distance sensors opposite the
direction of motion of the conveyor belt at approx. 100 mm in front of the reading
pulse sensor.

4. Set the focus positions for the required reading ranges on the “READINGCONFIGURATION”
tab in the CLV Setup program.
To do so, click the “DISTANCE CONFIGURATION /ASSIGNMENT TABLE” button and edit the
required entries in the dialog box that is then displayed.
5. As described in Section 4.3.2, Page 4-8, choose the standard decoder and start
Percentage Evaluation mode temporarily.
6. Check the reading quality in all distance configurations while the conveyor belt is
stationary.
7.Then check the distance detection function in Reading mode under realistic conditions.
To do so, monitor the reading result in the Terminal Emulator as described in Section
4.4.2, Page 4-11.
Default:Focus position F 1 up to F 8 = 1,200 mm
The CLV can switch between a maximum of 8 distance ranges for slow search runs using
the integrated timer or the oscillating mirror reversal points.
The CLV can be switched between a maximum of 8 distance ranges synchronously to the
reading process using command strings.

triggered by external sensors, the sensors are connected to the five inputs IN 0 ... IN 4.
Together with the internal assignment table, these can be used to configure a maximum of
32 switching states for up to 8 distance configurations. The dynamic focus control function
is selected for all inputs by default
Additional function IN 3:
The input IN 3 can also be used as a trigger source for the one-shot function of the
oscillating mirror.
Additional function IN 4:
The input IN 4 can also be used as a trigger source for the one-shot function of the
oscillating mirror or as an input for a belt increment signal. In this case, a maximum of 16
switching statuses can be used for dynamic focus control.

5.5.7Connecting the “Result 1” and “Result 2” switching outputs
The four switching outputs can be assigned different functions for outputting result statuses independently of each other. If the assigned event occurs during the reading procedure, the corresponding switching output becomes live at the end of the reading pulse for
the selected pulse duration. The pulse duration can be set individually for each output.
The “Read Result” LED is linked to the “Result 2” output and lights up in Reading mode for
the selected pulse duration and function of the result status display (default: “Good Read”,
100 ms).
Fig. 5-6 shows the connections for the “Result 1 ... Result 4” switching outputs.

Recommendation
Ø To check the switching functions using a high-impedance digital voltmeter, connect a
load to the outputs to prevent incorrect voltage values/switching statuses from being
displayed.
• Start up the CLV with the factory default settings (quick start).
With this configuration, the CLV can be operated without being connected to a PC
(this is, however, not the case the first time the CLV with external parameter memory is
switched on)
• Connect the PC (see Section 5.5.5, pages 5-15) and install the CLV Setup program
(see Section 10.6, Pages 10-23).
• Configure (parameterize) the CLV for the desired application with CLV Setup or com-
mand strings
6.2Default settings
Table 6-1 and Table 6-2 contain an overview of the factory default settings for the CLV.
The default parameters are such that the CLV can be put into operation either straight
away or following a few minor adjustments. A PC does not need to be connected to start
up the CLV with the default settings (this is, however, not the case the first time the CLV
with external parameter memory is switched on).
The default settings are stored permanently both in the ROM and in the CLV Setup database. They can be loaded to the RAM of the CLV at any time and displayed in the tabs of
the CLV Setup program.
Displaying and printing out a complete set of default settings in CLV Setup
1. To save the current settings in the parameter set:
Choose “FILE” and “SAVE AS”, and enter a file name in the dialog box that appears.
CLV Setup saves the current settings in a configuration file with the extension ”*.scl”.
2. Click in the toolbar.
CLV Setup loads the default settings from its internal database and displays them in
the tabs.
3. Click in the toolbar.
The “PRINT FILE” dialog box is displayed.
4. If desired, a comment can be entered in the input field for the header of the printout.
Confirm the entry with OK.
The “PRINT” dialog box for configuring the printer then is displayed.
5. Make the appropriate entries in the dialog box and confirm these with OK.
CLV Setup prints out the complete set of default settings in the form of a table. The
header contains the company and user names that were entered during the CLV Setup
installation routine.

A PC does not need to be connected when the CLV is operated with the factory default
settings (this is, however, not the case the first time the CLV with external parameter
memory is switched on, see Section 6.3.2, Page 6-4).
6.3.1Switching the CLV on for the first time with the factory default settings
1. Connect the CLV to the AMV/S 60 Connection Module using the two cables
no. 2 020 302.
2. Connect the reading pulse sensor (e.g. photoelectric reflex switch) to the “Sensor”
switching input of the CLV via the AMV/S 60 (see Section 5.5.6, Page 5-16).
3. Switch on the power supply of the AMV/S 60.
The CLV starts. The “Device Ready“ LED lights up. The “Result 1” (“Device Ready”)
output switches.
CLV with external parameter memory connected:
If an external parameter memory is connected to the CLV, the Device Ready LED
blinks for 10 s when the device starts up correctly and then lights up constantly.
If the Device Ready and Read Result LEDs both light up constantly, the memory is
empty and the CLV is not ready for operation.
In this case, proceed as described in Section 6.3.2, Page 6-4.
Line scanner with oscillating mirror:
In the default setting, the CLV deflects the scan line around the position CW =50 with
a frequency of 1 Hz and an oscillating amplitude of ±20° (±40 CW).
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
scan line appears.
5. Present the bar code pattern (Fig. 6-1) to the CLV at the reading distance specified in
Table 6-3.
6. Align the bar code in such a way that the red scan line is almost at a 90° angle to the
bars (line scanner) or that the red scan line sweeps the bars at a 90° angle when it is
deflected (oscillating mirror).
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 the laser diode off.
The CLV confirms that the bar code was read successfully (the “Result” LED lights up
for 100 ms). The “Result 2” (“Good Read”) output is switched for a 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.

6.3.2Switching the CLV with external parameter memory connected on for
the first time with the factory default settings
1. Connect the CLV to the SICK AMV/S 60 Connection Module via the external param-
eter memory no. 2 020 307 using the two cables.
2. Connect the reading pulse sensor (e.g. photoelectric reflex switch) to the “Sensor”
switching input of the CLV via the AMV/S 60 (see Section 5.5.6, Page 5-16).
3. Switch on the power supply of the AMV/S 60.
The CLV starts. In the default setting, the start option is set to STA RT WITHEXTERNAL
PARAMETERS
.
Once the CLV has started, the Device Ready and Read Result LEDs blink continuously.
This indicates that the CLV was able to address the external parameter memory but
the memory is empty (default state).
The CLV is then initialized with its internal parameter set but does not output data on
its host interface. The CLV is not ready for operation!
Line scanner with oscillating mirror:
In the default setting, the CLV deflects the scan line around the position CW =50 with
a frequency of 1 Hz and an oscillating amplitude of ±20° (±40 CW).
4. Connect the PC to the terminal interface of the CLV. To do so, connect the RS 232
cable (e.g. no. 2 014 054) to the Service connector in the AMV/S 60 (see Section
5.5.5, Page 5-15).
5. Start Windows and the CLV Setup program
(see Section 10.6.3, Page 10-25).
CLV Setup attempts by default to communicate with the CLV via COM 1. If the communication parameters match, CLV Setup uploads the current parameter set from the
RAM of the CLV to the internal database and displays the values in the tabs (the
parameter set contains the factory default settings when the scanner is switched on
for the first time). If necessary, choose “CLV 490” in the “DEVICE” drop-down list in the
top right-hand corner in order to initiate communication and the upload manually.
6. Choose the “DEVICE CONFIGURATION” tab.
7.Click the COPYINTERNðEXTERN field in the STA R TWITH box.
CLV Setup then instructs the CLV to copy the internal parameter set to the external
parameter memory the next time it starts.
8. Perform a download to the CLV by clicking in the toolbar.
CLV Setup copies the parameter set with the new start option by downloading it to the
CLV.
The “DOWNLOAD PARAMETERS” dialog box is then displayed.
6-4
9. Confirm the dialog box by choosing the “PERMANENT” storage option.
10. Disconnect the AMV/S 60 briefly from the power supply to restart the CLV.
Once the CLV has started, the Device Ready and Read Result LEDs blink alternately for
approx. 10 s before the Device Ready LED lights up constantly.
The “Result 1” (“Device Ready”) output switches.
The CLV has copied the parameter set to the external parameter memory and reset
the start option automatically to STAR T WITHEXTERNALPARAMETERS.
The CLV and external parameter memory are then ready for operation with the factory
settings. The next time the device is started, the Device Ready LED blinks for approx. 10 s
and then lights up constantly.
Continue the quick start as of Step 4 in6.3.1.
Chapter 6
6.4Configuring (parameterizing) the CLV
The CLV is configured locally in accordance with the application at hand. The read, evaluation and output characteristics can, therefore, be parameterized as required on the basis of
the factory default settings or an application-specific CLV parameter set that has already
been created.
The CLV supports four different configuration methods:
• Configuration via the CLV Setup program
(parameter values are set via the serial interface)
• Configuration via command strings
(parameter values are set via the serial interface).
See Section 6.4.4, Page 6-17.
In the Parameterization mode, the CLV outputs no reading result.
6.4.1Configuring the CLV via 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 Section 5.5.5, Page 5-15.
The procedures for installing and starting the CLV Setup program and for operating the
user interface are described in the Appendix (Section 10.6, Page 10-23).
Transferring a parameter set between CLV Setup and the CLV
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 upload during which CLV Setup always loads a
copy of the current CLV parameter set. This parameter set remains unchanged until it is
overwritten by CLV Setup.
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 loads 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 download.
Uploading a parameter set from the CLV
Ø 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 in 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 message. Unknown parameters can be edited in the “EXTRAS”
tab by following the conventions for command strings. When the parameter set is then
saved, these parameters are also saved.
Transferring a parameter set to the CLV and saving it (download)
1. Click in the toolbar.
The “Device Ready” LED is extinguished.
CLV Setup copies the parameter set to the RAM of the CLV.
The “DOWNLOAD PARAMETERS” dialog box with the storage options is then displayed.
“PERMANENT”:CLV Setup copies the parameter set to the RAM and to the
EEPROM of the CLV.
“TEMPORARY”:CLV Setup copies the parameter set to the RAM only.
The changes are lost when the CLV power supply is switched off.
2. Confirm the dialog box with the desired storage option.
The “Device Ready” LED lights up again.
The new parameter set is stored in the CLV either permanently or temporarily.
CLV with external parameter memory
If the parameter set was downloaded and stored permanently, CLV Setup opens a further
dialog box for adjusting the parameter set in the external memory, if the start option is set
to STAR T WITHEXTERNALPARAMETERS.
Ø Choose the COPYNOWINTERNALPARAMETERSETTOEXTERNALPARAMETERSET option.
CLV Setup then instructs the CLV to copy the new parameter set to the external
memory. The Device Ready LED lights up again.
The internal and external parameter sets are now identical.
See also Section 10.3.5, Page 10-18.
Saving a parameter set in CLV Setup
1. To save the modified parameter set as a new configuration file in CLV Setup, or to
overwrite an existing file, choose “FILE” and “SAVE AS”.
The “CLV FILE SELECTOR” dialog box is then displayed.
2. Enter the file name in the dialog box (file name extension “*.scl”) and confirm the
entry.
The new parameter set is now stored in CLV Setup in the subdirectory “data”.

Note
The minimum and maximum values for the active evaluation range of the scan line
(“MIN. AND MAX. CODE POSITION“) can be checked in the “SHOW CP-LIMITS” mode.
The OSCILLATEWITHVA RIAB LEAMPLITUDE operating mode can only be selected from amplitudes of
min. ±10 CW and an oscillating frequency of 0.4 Hz or higher.
The scan line must always sweep the neutral position (CW=50). This means that oscillation is not possible in the range 60 CW to 80 CW, for example, but is possible in the range
40 CW to 80 CW.
Explanation of oscillating mirror functions
1. “Oscillating with Maximum Amplitude” mode
The oscillating mirror deflects the scan line up to the maximum angle of deflection of
±40 CW (corresponds to ±20°). Fig. 6-2 illustrates this mode when a bar code is read
from above.
Constant

frequency

Scan line density depends on object height
Fig.6-2: Oscillating mirror: “Oscillating with Maximum Amplitude” mode
2. “Oscillating with Variable Amplitude” mode
The deflection range can be parameterized separately for each of the maximum of 8
distance configurations/focus positions. The minimum/maximum values that can be set for
the deflection range for fast applications ensure that the scan line only sweeps areas that
contain bar codes during the time available. This also ensures that the scan line density on
the object is, for the most part, constant. Fig. 6-3 illustrates this mode when a bar code is
read from above.
Scan line density constant irrespective of object height
Fig.6-3: Oscillating mirror: “Oscillating with Variable Amplitude” mode
3. “Fixed Position” mode
The CLV parks the oscillating mirror at the desired position. 10 CW corresponds to –20°,
and 90 CW to +20° (see Fig. 4-8, Page 4-6). In the default setting, the fixed position is
set to 50 CW (angle of deflection of 105°). The Oscillating mode is switched off.
4. “One-Shot” mode
In the “One-Shot” mode, the oscillating mirror only performs one specific oscillating movement per reading interval. This movement consists of a forward phase and a return phase.
The start position of the scan line, the mirror speed and the valid distance configuration
can be parameterized separately for each phase. The end position of the one phase forms
the start position of the other phase. Fig. 6-4 illustrates this mode with object tracking.
During the forward phase, the front of the object that moves towards the oscillating mirror
is swept once by the scan line from top to bottom in accordance with the conveyor speed.
Multiple focus position switchovers are not necessary as the required reading range (DOF)
is much smaller than with the line scanner. Fig. 10.7.2, Page 10-33 explains how the start
position and mirror speed are calculated for a given conveyor speed.

6.4.4Configuring the CLV with command strings
The CLV can be parameterized and operated via the terminal interface and the host
interface. Parameters that are not recognized by CLV Setup can also be used by following
the conventions for command strings. This enables special devices, for example, to be
parameterized and new CLV parameters to be configured which may not be recognized by
the CLV Setup program if this is older than the software on the CLV. The CLV Setup user
interface is based on the command language.
The command language accesses the command interpreter of the CLV directly and must
be used carefully. The commands sent to the CLV are output immediately. Parameter
values that have been changed by commands are initially only active in the current parameter set in the RAM of the CLV. Using a special command, the modified parameter set
must also be copied to the EEPROM so that it can be stored permanently, otherwise the
changes will be lost when the power supply is switched off.
The online mode of the terminal emulator in CLV Setup enables the CLV to parameterized
directly with command strings. Fig. 6-5 contains the initial screen of the terminal emulator
with the command field and output window which shows how the PC and CLV communicate with each other.
1. Click in the toolbar.
The terminal emulator window is then displayed. The CLV is in the Reading mode.
2. In the “SCANNER MODE” group, choose “PARAMETRIZE”.
The CLV exits the Reading mode and the “Device Ready” LED is extinguished.
CLV Setup switches the CLV to the Parameterization mode by issuing an appropriate
command. In the Parameterization mode, all commands begin with the number “3”.
3. Enter the desired command in the command field and press the <Return> key.
The command is then sent to the CLV.
With a few exceptions, the CLV replies to a command with correct syntax with an echo.
Entering “3?LT“ causes the CLV to output the values of the reading pulse communication parameter in encoded form in the output window .
4. Click the Reading Mode radio button to return to the Reading mode.
The “Device Ready” LED lights up.

Chapter 6
6.5.1Reading mode (standard operating mode)
The CLV performs a self-test after it has been switched on. It switches to Reading mode
(Device Ready LED lights up). In the default setting, the “Sensor“ 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 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 “READING DIAGNOSIS” mode for this
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.
Line scanner with oscillating mirror:
In the Reading mode, the CLV deflects (by default) the scan line about the position
CW=50 at a frequency of 1 Hz and a maximum angle of ±20°. 50 CW corresponds to an
angle of deflection of 105°.
Displaying the reading result in the terminal emulator:
1. Click in the toolbar.
The terminal emulator window is then displayed.
3. In the “SCANNER MODE” group, choose “READING MODE”.
3. Present the bar code pattern from Fig. 6-1 to the CLV and activate the reading pulse.
The “Sensor” LED lights up and the scan line appears.
See Section 6.3.1, Page 6-3.
4. Ending the reading pulse.
The CLV displays the reading result in the output window of the terminal emulator.
The “Read Result” LED lights up for a duration of 100 ms (default setting).
Fig. 6-6 shows two examples of a reading result: Good Read and No Read. The reading
result comprises the data contents of the bar code(s) and the reading diagnosis data.
Fig. 6-7 explains the structure and function of the reading diagnosis data for Good Read,
and Fig. 6-8 for No Read.

6.5.2Percentage evaluation
In the Percentage evaluation mode, the quality of the reading function is assessed (no
conveyor movement). The CLV performs 100 scans in the Free running mode and evaluates the reading quality. It outputs the reading result continuously every 2 s via the terminal interface. The reading results can be displayed in the terminal emulator of CLV Setup.
The standard decoder has to be set temporarily for the percentage evaluation.
The Percentage evaluation mode can be called up via “View” in the menu bar or via the
terminal emulator.
Line scanner with oscillating mirror:
In Percentage evaluation mode, the CLV switches of oscillating mode (default setting:
oscillating) and positions the scan line at the angle 50 CW, corresponds to an angle of
emergence of 105°. The angle can not be changed.

The “Read Result” LED also provides information on the reading quality:
- LED is extinguished if reading quality is < 30%
- LED flashes twice per second if the reading quality is 30% ... 70%
- LED flashes five times per second if the reading quality is 70% ... 90%
- LED is lit continuously if the reading quality is >90%
Fig.6-9: CLV Setup: Displaying the percentage evaluation in the terminal emulator
The output format of the reading result is the same as that of the Reading mode. Fig. 6-7,Page 6-20 explains the structure and function of the reading diagnosis data.
6.5.3Adjusting mode
The Adjusting mode enables the center of the scan line to be optimally positioned on the
bar code. Section 4.3.3, Page 4-9 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 device
function via “Tools” (interactively), or via the terminal emulator.
Line scanner with oscillating mirror:
In Adjusting mode, the CLV switches of oscillating mode (default setting: oscillating) and
positions the scan line at the angle 50 CW, corresponds to an angle of emergence of
105°. The angle can not be changed.
1. Click in the toolbar.
The terminal emulator window is then displayed. The CLV is in the Reading mode.
2. In the “SCANNER MODE” group, choose “ADJ USTING MODE”.
The “Device Ready” LED is extinguished, The CLV cancels the Reading mode and
blanks the scan line as of position CP=50 to position CP=100.
3. Choose “READING MODE” to exit the Adjusting mode.
The CLV returns to the Reading mode and the “Device Ready” LED lights up.
If the Autofocus function is used in the DIFFERENCETOBACKGROUND or DIFFERENCETOBACKGROUND
WITH
TRACKING mode, the CLV must first learn the ambient background in its visible range
before a successful read can be carried out. When the internal distance profile is set, the
visible range of the CLV must not contain any objects. In this mode, the CLV does not
output any reading results.
The background teach-in function can only be started as a device function under TOOLS.
Line scanner with oscillating mirror:
When the background teach-in function is active, the CLV deactivates oscillating mode
(default setting: oscillating with fixed amplitude) and positions the scan line at an angle of
CW=50 (equal to an angle of emergence of 105°). This angle cannot be modified.
1. Mount the CLV at the reading station and align it with an object containing a bar code.
2. Remove the object so that the CLV has an unobstructed view of the background.
3. Choose TOOLS, DEVICEFUNCTIONS.
The EXECUTEDEVICEFUNCTIONS window opens.
4. From the menu bar, choose EXECUTE, BACKG RO U NDTEACH-IN.
The Device Ready LED goes out. The CLV then scans its visible range and learns the
ambient background so that it can create a suitable distance profile.
The CLV outputs a message once the teach-in procedure has been successfully
completed (see Fig. 6-10).
The CLV has then learned the ambient background.
5. Choose CLO S E to close the window.
If the parameters in the CLV were modified as a result of the teach-in procedure, CLV
Setup asks you whether you want to copy and display the modified parameter set by
uploading it from the CLV.
6. Confirm the query with YES.
The dialog box closes automatically.
The CLV then resumes Reading mode and the Device Ready LED lights up.
The new background distance profile can be uploaded and displayed in CLV Setup.

6.5.5Show CP-limits
In this mode, the CLV blanks 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 only has to take account of
unblanked parts of the scan line. The range is restricted by entering appropriate values for
“MINIMUM CODE POSITION” and “MAXIMUM CODE POSITION” in the “EDIT AUTOFOCUS“ respectively “EDIT
DISTANCE CONFIGURATIONS” dialog box in the “READI NG CONFIGURATION” tab.
The CLV does not output a reading result in this mode.
• the visible range of the CLV has been defined accordingly for the selected setting in
Autofocus mode (restriction is independent of reading distance and always the same)
• the restriction has been adapted for each active distance configuration in event-control-
led dynamic focus control (Christmas tree effect)
Show CP-limits can be called up via “View” in the menu bar, as a device function via “Tools”
(interactively), or via the terminal emulator.
Line scanner with oscillating mirror:
In Show CP-limits mode, the CLV switches of oscillating mode (default setting: oscillating)
and positions the scan line at the angle 50 CW, corresponds to an angle of emergence of
105°. The angle can not be changed.
The CLV blanks the scan line alternately as of the set value for CP
value for CP
. Fig. 6-12 shows an example of this. The switchover is made continuously

Proceed as follows to check the restricted evaluation range:
1. Click in the toolbar.
The terminal emulator window is then displayed. The CLV is in the Reading mode.
2. In the “SCANN ER MODE” group, choose “SHOW CP-LIMITS”.
The dialog box for the distance configuration is then displayed.
3. Click the distance configuration for which the active evaluation range of the scan line
has been restricted (DC-specific). The “Device Ready” LED is extinguished. The CLV
cancels the Reading mode and blanks the scan line alternately (as described above)
as of CP
and CP
min
max
.
4. Check Step 2 and 3 for each active distance configuration to determine whether the
bar code is in the center of the range between the end of the shorter scan line (CP
and the end of the longer scan line (CP
) or, if there are several bar codes, to deter-
max
min
)
mine whether the center of the field of all the codes is within the range.
6. Choose “READING MODE” to exit the Show CP-limits mode. The CLV returns to the
Reading mode and the “Device Ready” LED lights up.
Chapter 6
Note
In the Reading mode, the CLV does not actually blank the scan line visually, but instead
takes the values specified for the restricted evaluation range into account when the data
contents are decoded.
6.5.6Displaying and editing operating data
This function enables statistical operating data, which the CLV maintains in the form of
counters during the reading procedure, to be displayed and reset.
The CLV does not output a reading result in this mode.
1. Click in the toolbar.
The CLV cancels the Reading mode and the “Device Ready” LED is extinguished.

The CLV then returns to the Reading mode and the “Device Ready” LED lights up.
Fig.6-13: CLV Setup: “Operating Data” dialog box
6.5.7Reading 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.
Fig. 6-7, Page 6-20 shows the output format of the terminal interface.
In the default setting, the CLV only outputs the error status ST in the separator via the
host interface.
If the reading diagnosis is to remain inactive, this can be set via the “AUXILIARY INTERFACE” tab.
1. In the “AUXILIARY I NTERFACE” drop-down list, choose “READ DIAGNOSTICS”.
2. Perform a download to the CLV by clicking in the toolbar.
The “DOWNLOAD PARAMETERS” dialog box is then displayed.
3. Choose the “PERMANENT” storage option in the dialog box.
The terminal interface is now set to the “Read Diagnostics” mode.
6.5.8Monitor Host Interface
Function of the terminal interface. In this mode, the CLV outputs the data traffic of its
host interface via the terminal interface. Protocol driver handshakes and protocol-specific
data, such as start and stop characters, are suppressed here (Table 6-9). Each data string
is displayed on a separate line on the screen. Two monitoring modes are available that
differ with regard to the data output format.

Note
TIP
Fig.6-14: CLV Setup: Displaying the reading result of the host interface in the terminal emula-
tor with direction identifier at the beginning (in this case: O=Output)
With large volumes of very fast host interface data, it is possible that the flow of data
traffic will not be displayed in full (display: “...”). This is due to the slower transmission rate
of the terminal interface (9600 baud).
In the default setting, the CLV sends the following in the data output string of the host
interface:
• data contents of the bar code
• the ST error status in the Separator
• the control characters in the Terminator
The Header is blank.
The structure of the data output string of the host interface can be configured via the
“DATA STRINGS” tab.
Up to 10 elements, consisting of constants and/or reading diagnosis data, can be entered
in the header, in the separator and in the terminator.
1. Choose the “DATA STRINGS” tab.
2. Click the “HEADER” drop-down list.
The “EDIT PARAMETER TFH” dialog box is then displayed.
3. Click the desired constants or placeholders for the reading diagnosis data.
The selected elements appear in the text box at the top of the dialog box in the
sequence in which they were selected.
5. Repeat this procedure for the separator and terminator.
6. Perform a download to the CLV by clicking in the toolbar.
The “DOWNLOAD PARAMETERS” dialog box is then displayed.
7.Choose the “PERMANENT” storage option in the dialog box.
The CLV outputs the selected elements in the data output string of the host interface
with the next reading result.
6.5.9Auxiliary input
Function of the terminal interface. In this mode, the CLV accepts a bar code entered at
the terminal interface (via the keyboard or handheld 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.
Section 10.9.1, Page 10-36 describes this function and the associated procedure in
greater detail.
6.5.10Self-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
self-test, 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 the Reading mode.
2. In the “SCANNER MODE” group, choose “SELF TEST”.
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 (Fig. 6-15).
3. To return to the Reading mode, click “READING MODE” or close the terminal emulator.
The CLV then returns to the Reading mode and the “Device Ready” LED lights up.

The code number “15000” means that the self-test was completed successfully and
that no faults were diagnosed.
Section 8.3.1, Page 8-2, lists the error keys together with the associated corrective
measures.
6.5.11Executing CLV functions interactively
CLV Setup enables a number of CLV functions to be executed interactively. CLV Setup
prompts the user to carry out specific actions and provides information on the progress
of the function being executed.
The following functions are available:
• Background teach-in
• Show CP-limits
• Adjustment mode
1.In the menu bar, choose “TOOLS” and “DEVICE FUNCTIONS”.
The “EXECUTE DEVICE FUNCTIONS” dialog box is then displayed.

Section 8.3.1, Page 8-2 lists the messages in alphabetical order together with the associated corrective measures.
6.7Switching off the CLV
1. If the parameter set was modified in CLV Setup or was only stored temporarily in CLV
via a download, the parameter set must be stored permanently in the CLV by choosing
the “PERMANENT” storage option.
2. Save the parameter set as a configuration file in CLV Setup.
3. Switch off the power supply of the AMV/S 60.
The last parameter set stored permanently in the CLV remains valid.
We recommend that you print out the configuration file in order to archive the parameter
set.
1. Click in the toolbar.
The “PRINT FILE” dialog box is then displayed.
2. Enter a comment in the input field in order to assign the printout to the CLV.
Confirm your entry with OK.
The “PRINT” dialog box for configuring the printer is then displayed.
3. Make the necessary entries in the dialog box and confirm these.
CLV Setup prints out the configuration file in the form of a table.
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 beam can cause blindness!
The CLV uses a class 2 red-light laser. Looking directly at the laser beam can seriously damage your eyesight.
Ø As with sunlight, never look directly into the laser beam.
Ø Switch off the device while it is being cleaned.
Ø Never look directly into the reading window while the device is in operation.
IM PORTANT
Damage on the reading window!
The reading window is made of glass. Scratches and streaks on the window will reduce the
reading performance.
Ø Use a mild, non-scouring detergent
Ø Never use scratching or scouring motions to clean the reading window
Cleaning the reading window:
Ø Clean the reading window at regular intervals with a mild, non-scouring detergent, e.g.
an antistatic glass cleaning fluid. Fig. 7-1 shows the areas that require cleaning. Use a
soft, lint-free cloth.
Ø If necessary, clean the LEDs on the rear of the device.
Cleaning other optical surfaces:
Ø If an external reading pulse generator and/or object-height detection sensors are used
(e.g. photoelectric reflex switches), make sure to clean the relevant optical surfaces
(Fig. 7-2). Contamination on these surfaces can cause switching errors.
