2.2Intended use
The CLV is designed to detect and decode bar codes automatically. It is mounted in a
reading station and reads bar codes on objects positioned on a conveyor belt, for example.
In stand-alone configuration the CLV transfers the data content of the decoded bar codes
via its host interface to a host for further processing. Being integrated in the OTS 400 Omni
Tracking System together with other CLVs, the CLV transfers the read results via its CAN in
terface to the OTC 400 Omni Tracking Controller.
Any warranty claims vis-à-vis SICK AG will be rendered invalid if the device is used for any
other purpose or if changes are made to the device, also as part of the mounting and
electrical installation procedures.
NoteDon’t open the device. The producer warranty will be forfeited if the device is opened.
2.3General safety instructions and protection measures
¾ Always read the general safety instructions carefully and observe them at all times.
Please also observe the warnings in front of the operating instructions in each chapter
of this document.
Shock hazard
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.
¾ 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.
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.
¾ As with sunlight, never look directly into the laser beam.
¾ Do not direct the laser beam at other persons.
¾ Mount and align the CLV in such a way to prevent the laser beam reflecting off mirrored
surfaces.
¾ Do not open the housing.
(Opening the housing does not deactivate the laser diode).
¾ Observe the laser protection specifications (latest version).
Laser power
The laser operates at a wave length 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.
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 symbols (Fig. 2-1) can be found on the CLV at the following locations:
•The laser warning symbol on line scanners is positioned beside the reading window on
the front side of the device. The laser warning in GB English/US English is located on the
side containing the electrical connections
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 bottom.
•The laser warning symbol on line scanners with oscillating mirror is located above the
reading window, on the cover of the mirror. The laser warning in GB English/US English
is located on the side containing the electrical connections
The additional laser warnings in English applicable to the USA are positioned on the cover of the mirror and on the front side of the decive at the bottom.
NoteA set of laser warnings in German/US English and French/US English is included in the
delivery scope. The GB English/US English warnings can be pasted over with these if
necessary.
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
The CLV is equipped with monitoring circuits that deactivate the laser diode in the event of
a malfunction. No maintenance required to keep this product in compliance with laser
class II.
Activation and deactivation of the laser diode is controlled by the reading pulse trigger.
A timer (laser timeout) 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 (default setting). 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.
The laser timeout can be set in the range of 1 min to 25 h or deactivated (see Table 6-17,
Page 6-23)
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.
¾ Switch off the power supply or remove the cables of the CLV from the connection
module.
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, number of reading triggers, number of Good Reads, number
of No Reads, maximum duration trigger, minimum duration trigger, number of matches
with match code 1, number of matches with match code 2, numbers of No Matches)
2.4.2Restarting the CLV
¾ Switch on the power supply or reattach the cables of the CLV to the connection
module.
The CLV resumes operation with the parameter set that was last stored permanently
and reset the daily operating data.
2.5Environmental information
The CLV is designed to cause minimum impact on the environment. It does not contain any
silicone-based materials on the housing surface and, therefore, does not represent any pro
blems for paint sprayers in paint shops, for example.
2.5.1Power requirements

Product description
CLV 480 Bar Code Scanner
3.2Method of operation
The CLV first scans the bar code with a scan line and then decodes it. In stand-alone configuration, the data is forwarded via the serial host interface (main data interface) to a host/
PC for further processing, or via the CAN interface to the OTS 400 Omni Tracking System.

Fig. 3-2: Block diagram: CLV functions
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 can transfer it to also
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 an internal 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: OTS trigger).
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 "IN 0" to "IN 4" switching inputs switch the focus position in
response to certain events, as an alternative to the autofocus function. The "IN
"IN
4” inputs can also be assigned special functions. The four "Result 1" to "Result 4"
3" and
switching outputs can be assigned to different functions for displaying the result status and
also control 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 interface/terminal interface using command
strings.
System and error messages help you to configure the device and to locate the source of
errors during startup and reading mode.
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 (see
Fig. 3-3).

Reading distance
The switch over takes place in response to changes in the object distance (with reads from
above: object height detection). The trigger source for the switchover can be:
•A signal combination at the "IN 0" to "IN 4" switching inputs, a command on the host
interface/terminal 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 switchover sequence by means
of a programmable assignment table.
•In combination with the OTS 400 Omni Tracking System:
Alternatively the object height information from the OTS 400 or any other CLV via the
CAN bus.
3.2.2Reading modes
Start/stop mode
During the reading process, only one object is located in the reading field in start/stop
mode, i. e. all read bar codes can be clearly assigned to the object. As default, two reading
pulse sensors at the beginning and at the end of the reading field control the starting and
stopping of the reading process (
Fig. 3-4). The size of the reading field is determined by the
distance between the two sensors. Alternatively, the reading process can be controlled with
command strings via the data interface or can be left free running. The CLV either outputs
the reading result at the end of the reading pulse (the back edge of the object has left the
end of reading field) or already during the reading pulse as a result of predefined (parame
trized) conditions. To separate bar codes of the same type with identical contents, an incremental encoder must be connected to the CLV.
In object polling mode, the CLV automatically detects the beginning and the end of the object located in the reading field without any help of external sensors. The minimum temporal
distance between two consecutive objetcs must not fall below 70 ms when the objects are
moved on the conveyor belt.
Tracking mode (in combination with the OTS 400 Omni Tracking System)
In tracking mode with the OTS 400 Omni Tracking System, max. 20 objects can simultaneously be located in the reading field (following each other), i. e. the CLV must be able to clearly assign the bar codes to the objects (Fig. 3-4). As default, a reading pulse sensor at the
beginning of the reading field controls the starting of the reading process. The end of the
reading field is determined by the parametrized object release point in the OTC 400 Omni
Tracking Controller. In this way, the size of the reading field is clearly determined.
In order to track the transport of the objects in the reading field, a regularly-timed pulse is
required. This is generated by an external incremental encoder for the OTC 400 which re
gularly supplies a pulse at least every 10 mm (0.39 in) of movement in conveying direction.
As a result, the the distance between the reading pulse sensor and the object release point
is clearly time-mapped in the CLV. Fluctuations when approaching the conveyor or decrea
ses in speed due to heavy load with numerous conveyor obejcts are also recorded. An internal clock in the CLV also allows operation at a constant conveyor speed. A gap of at least
50 mm (1.97 in) is necessary for the clear separation of consecutive objects. The reading
result for an object is output by the OTC 400 after the back edge of the object passes the
object release point. Alternatively, the reading process can be started with a command
strings via the data interface.

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 (fixed position) 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)
3.2.4Additional components
Heater
The CLV can be permanently equipped with a heater for applications involving temperatures
up to max. –35 °C (–31 °F), e. g. in a freezer.
The design, technical data, and power-up behavior of the CLV are described in Chapter 10.4
Optional heating, Page 10-26.
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 Chapter 10.3 Installing and
operating the external parameter memory, Page 10-22.

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 inter
face. 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/CAN interface
•The structure of the data output string for "Good Read" and "No Read" on the host in-
terface/CAN interface
•The function of the terminal interface
Chapter 10.6 Installing and operating the "CLV-Setup" program, Page 10-29 describes the
procedure for installing the "CLV-Setup" program and explains how to use it. The parameterization (configuration) procedure is explained in Chapter 6.4 Configuring (parameterizati-
on) the CLV, 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 (
Page 3-10).
If the optional external parameter memory is connected, the LEDs also indicate whether the
memory was successfully accessed.
• Blinks for approx. 10 s before lighting up constantly
(CLV has loaded the parameter set from the external parameter
memory and starts reading mode straight away)
• Blinks for approx. 10 s together with the "Read Result" LED, then lights up
constantly.
(CLV has loaded the parameter set from the external parameter memory with
tolerated errors
• Lights up constantly
(CLV could not find an external parameter memory and loads the internal parameter set instead)
• Blinks constantly together with the "Read Result" LED
(The external parameter memory contains the parameter set for a different CLV
type, or is corrupt.)

4.2Preparations
4.2.1Required components
•CLV Bar Code Scanner
4.2.2Required accessories
•SICK mounting bracket for the CLV: depending on the order,
angle bracket no. 2 013 824, articulated bracket no. 2 018 435, or quick-clamping
device no. 2 016 110 with securing material for the CLV
– 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 (3.3 lb) and 2.2 kg (4.84 lb) as
a line scanner with oscillating mirror.
– 2 screws M6 for the CLV. The screw length depends on the wall thickness of the brak-
ket used. Depth of engagement in CLV max. 7 mm (0.28 in) from housing surface.
•AMV/S 60 Connection Module (not included in the scope of supply of the CLV)
•Reading pulse sensor(s) for external reading pulse triggering, e. g. photoelectric reflex
switch(es)/photoelectric proximity switch(es) (not included in the scope of supply)

•German/US laser warning and
•French/US laser warning
See also Chapter 2.3 General safety instructions and protection measures, Page 2-2.
Supplied 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 1,200 m (3,937 ft) 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 5-9).
Distance between the CLV and the AMV/S 60 Connection Module
The AMV/S 60 Connection Module should not be located further than 10 m (32.8 ft) from
the CLV, since the "CLV-Setup" program on the PC accesses the terminal interface (RS 232)
of the CLV via this module.
The CLV is secured in position using the two tapped blind holes (M6) above the electrial connections. Fig. 4-2 shows the location of the threads near the line scanner.
The dimensions of the CLV housing are shown in Fig. 9-1 to Fig. 9-2, Page 9-4.

Depending on the application, the line scanner or line scanner with oscillating mirror versions
of the CLV is used.

Fig. 4-4: Scanning methods: alignment with bar code and conveyor direction
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) depending on the CLV type in
Chapter 10.2
Specification diagrams, Page 10-1.
Fig. 4-5 shows the definition of the reading distance a (radial measured) from the reading
window and of the aperture angle α each of the two scanning methods.

105°
Fig. 4-5: Definition of the reading distance a and of the aperture angle α
The useful aperture angle is typically 60° 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 readling distance.
Table 4-1: Permissible reading angles between the scan line and bar code
NoteIf reading from the front, mount the CLV above the conveyor belt in such a way against the
conveying direction that the scan line hits the object under a skew of approx. 10°.
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).

Fig. 4-7: Avoiding surface reflections: Angle between the emitted light and the bar code (tilted
away from the vertical axis)
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
NoteIn 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
ExplanationThe CLV can scan and decode several bar codes with each read. In doing so, it determines
the specific local reading diagnosis data for each bar code:
•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.

In the default setting, the CLV does not output the "CP" and "CW" values (line scanner with
oscillating mirror only) in the reading result on the host interface. If this is required to
evaluate the result in the host, the values can be included in the "Code-Info/Separator"
block of the output string using the "CLV-Setup" program.
Configuring the Code-Info/Separator:
1.Choose the DATA STRINGS tab.
2.Click the CODE INFO/SEPARATOR field.
The EDIT PARAMETER TFS dialog box is displayed.
3.In the list field, click the CP and/or CW parameters.
5.Download the data to the CLV by clicking in the toolbar.
The DOWNLOAD PARAMETERS dialog box is then displayed.
6.Confirm the dialog box by choosing PERMANENT.
The CLV outputs the CP value and the CW value on the host interface for each bar code
in the reading result. The values are displayed as a 3-digit number in the associated
"Code-Info/Separator" block.
4.3Mounting and adjusting the device
4.3.1Mounting the CLV
1.Prepare the base for mounting the bracket as described in Chapter 4.2.2 Required ac-
cessories, Page 4-1.
2.Place the object containing the bar code within the reading field 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 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
5.Mount 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 blind hole threads M6 is 7 mm (0.28 in).
Longer screws will damage the device.
¾ Use screws with the correct length.
6.Screw the screws M6 through the bracket into the blind hole threads of the CLV.
7.Tighten the screws slightly.
8.Adjust the CLV as described below.
4.3.2Adjusting 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 mo
ved 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 is extinguished if reading quality is < 30 %
–The LED flashes twice per second if the reading quality is 30 % to 70 %
–The LED flashes five times per second if the reading quality is 70 % to 90 %
–The LED is lit continuously if the reading quality is > 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
Chapter 5.5.3 Connecting the supply voltage, Page 5-14).
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. To do so, connect a 3-core RS 232
data cable (null modem cable) to the internal
9-pin "Service" plug of the AMV/S 60 (see
Chapter 5.5.5 Connecting the CAN interface, Page 5-16).
3.Start Windows and the "CLV-Setup" program (see Chapter 10.6.3 Starting CLV-Setup,
Page 10-32).
Choosing the standard decoder:
4.Choose the CODE CONFIGURATION tab.
5.Click the STANDARD option in the DECODER section.
6.Download the settings to the CLV.
To do so, click again the STANDARD option with the right mouse button and choose
D
OWNLOAD PARAMETER in the context menu.
CLV-Setup copies the parameter temporary to the CLV.
The CLV operates with the standard decoder (until the CLV is switched off).
Activating Percentage Evaluation mode:
7.From the VIEW menu, choose PERCENTAGE EVALUATION.
The dialog box for entering the distance configuration appears.
8.Click the relevant distance configuration for the reading distance:
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
(47.3 in)).
9.Confirm the dialog box with OK.
The Terminal Emulator is launched and displays the reading result continuously (see
Chapter 6.5.2 Percentage evaluation, Page 6-28).
Monitor the reading quality (%) during each of the subsequent steps!
Line scanner with oscillating mirror:
In the "Percent Evaluation" mode, the CLV behaves in the following manner:
– in "Oscillating" mode (default setting: oscillating with a fixed amplitude), the CLV shuts
off oscillation and positions the scan line under the angle CW
an angle of deflection of 105
°). This position cannot be altered.
= 50 (corresponds to
– in "One-Shot" mode, the CLV also positions the scan line under the angle CW = 50
– in "Set Position" mode, the scan line’s selected position remains unchanged.
Performing fine adjustment:
10. 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 li
nes, when it is in the neutral position (CW = 50).
11. To avoid interfering reflections, tilt the line scanner away from the vertical axis so that
the light strikes the bar code at an angle of approx. 105
° (see Fig. 4-7, Page 4-5).
12. If necessary, position the scan line exactly at the direct center of the bar code.
Chapter 4.3.3 Help functions for adjusting the CLV below.
13. 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.
14. Adjust the CLV in such a way that the good read rate is between 70 to 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
Chapter 6.4.3 Guide to parameterization menu, Page 6-9).
15. Tighten the screws on the CLV.
The CLV is aligned with the bar code.
4.3.3Help functions for adjusting the CLV
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). This is irrespective of whether the CLV is operated in Autofocus mode or with
distance configurations for event-driven dynamic focus control.

In "Adjusting" mode, the oscillating mirror behaves in the same manner as within the ”Percent Evaluation” mode (see Chapter Activating Percentage Evaluation mode:, Page 4-8).
1.Activate the operating mode as described in Chapter 6.5.3 Adjusting mode, Page 6-30.
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.
Show CP Limits
The "Show CP Limits" operating mode allows you to test whether the desired effect was produced by narrowing the scan line’s active evaluation range. The CLV alternatively hides certain parts of the scan line in accordance with the selected min. and max. values of the code
position.
For activation of this operating mode and for checking, See Chapter 6.5.4 Show CP-limits,
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 (32.8 ft).
2.Mount the AMV/S 60 in such a way that accessed to the open device is always possible. The terminal interface of the CLV is accessed via the internal "Service" plug.
Detailed information on the mounting and electrical installation procedures is provided in the
Operating Instructions "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.

These settings are not required if the CLV is operated with the default configuration.
1.Choose the DEVICE CONFIGURATION tab.
2.In the READING TRIGGER PARAMETERS section click the option SENSOR INPUT (ACTIVE HIGH).
3.Download the settings to the CLV by clicking in the toolbar.
The DOWNLOAD PARAMETERS dialog box is then displayed.
4.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 input is energized (high).
4.4.3Installing incremental encoder
To separate bar codes with the same name (same code type, identical data content), an
incremental encoder is required.
1.Install the incremental encoder (e. g. no. 2 022 714) near the CLV but in front of it,
preferably against the direction of the conveyor belt. The increment pulses must
originate from the area of the conveyor belt which the CLV is reading.
2.Ensure that the incremental encoder is contacting the conveyor and that the friction
wheel turns without slipping.
3.Connect incremental encoder to "IN4" switching input of the CLV. See Chapter 5.5.8
Connecting the "IN 0" to "IN 4" switching inputs, Page 5-18.
4.4.4Mounting 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 for
med 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 "IN 0" to "IN 4" switching inputs are selected for dynamic focus control.

5.5.8Connecting the "IN 0" to "IN 4" switching inputs
If the Autofocus function is not used and the CLVs dynamic focus control function is to be
triggered by external sensors, the sensors are connected to the five inputs "IN 0" to "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 "IN 3" input 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
•An input for a belt increment signal in reading mode for separating bar codes of the
same symbology with identical content
•A trigger source for the end of reading interval
In this case, a maximum of 16 switching statuses can be used for dynamic focus control.
Fig. 5-5 shows the connections for the "IN 0" to "IN 4" switching inputs. Table 5-18 shows
the pin assignment on the CLV and the terminal assignment in the AMV/S 60. Table 5-19,
Page 5-19 contains the characteristic data for these inputs. Table 5-20, Page 5-19 shows

5.5.9Connecting the "Result 1" to "Result 4" 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 selec
ted 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, Page 5-21 shows the connections for the "Result 1" to "Result 4" switching out-
puts. Table 5-22, Page 5-21 shows the pin assignment on the CLV and the terminal assignment in the AMV/S 60. Table 5-23, Page 5-21contains the characteristic data for these
outputs. The four outputs have the same characteristic data.

•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.
•Connect the PC (see Chapter 5.5.5 Connecting the CAN interface, Page 5-16) and in-
stall the "CLV-Setup" program (see Chapter 10.6 Installing and operating the "CLV-Set-
up" program, Page 10-29).
•Configure (parameterize) the CLV for the application.
6.2Default settings
Table 6-1, Page 6-2 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.
The default settings are stored permanently both in the ROM of the CLV and in the CLVSetup 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 SAVEAS, 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 PRINTFILE 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 need not to 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).
6.3.1Starting up the CLV 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 Chapter 5.5.7 Connecting the "Sen-
sor" switching input, Page 5-17).
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
(default setting: Start with external parameters):
If an external parameter memory containing a corresponding parameter set 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 external parameter memory is empty, the CLV
immediately copies its parameter set to the external parameter memory. Then the "De
vice Ready" LED lights up. The CLV is 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
to a deflection angle below 105
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 (Fig. 6-1) to the CLV at the reading distance specified in
Table 6-3, Page 6-4.
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
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 "Read 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.

The CLV adapts to the reading situation locally with the configuration. 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 two 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 Chapter 10.7 Configuring a CLV with command strings, Page 10-39.
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
CAN interface, Page 5-16. The procedures for installing and starting the "CLV-Setup" pro-
gram and for starting and operating the user interface are described in the Appendix
(
Chapter 10.6 Installing and operating the "CLV-Setup" program, Page 10-29).
Chapter 5.5.5 Connecting the
Transferring a parameter set 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 upload ("Upload from CLV" in the CLV
menu or [F3] key) during which CLV-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 download ("Download to CLV" in the CLV
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 temporarily loaded into the CLV’s memory

again to the CLV with the "Permanent" option.

Loading a complete CLV parameter set (upload)
¾ Click in the toolbar or press [F3] key.
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 parameters transferred during the upload, it
outputs a warning message. Unknown parameters can be edited in the E
XTRAS tab by
following the conventions for command strings. When the parameter set is then saved, the
se parameters are also saved.
Transferring and saving a complete CLV parameter set (download)
1.Click in the toolbar or press [F4] key.
The "Device Ready" LED is extinguished.
CLV-Setup copies the parameter set to the RAM of the CLV. The DOWNLOADPARAMETERS
dialog box with the storage options is then displayed.
PERMANENT: CLV-Setup copies the parameter record to the RAM and to the EEPROM of
the CLV.
TEMPORARY: CLV-Setup copies the parameter record to the RAM only. The changes are
lost when the CLV supply voltage 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 dependent of
the selected option
.
-
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 S
TARTWITHEXTERNALPARAMETERS.
¾ Choose the COPYNOWINTERNALPARAMETERSETTOEXTERNALMEMORY 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 Chapter 10.3.5 Adjusting the parameter set in the external parameter memory af-
ter it has been downloaded to the CLV, Page 10-24.
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 SAVEAS.
The FILESAVEAS 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".
NoteThe OSCILLATEWITHVARIABLE AMPILTUDE 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 fixed 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.

Scan line density depending on object height
Fig. 6-2: Oscillating mirror: "Oscillating with fixed 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.

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 (corresponds to an angle of deflection below 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. 10-32, Page 10-43 explains how the start position
and mirror speed are calculated for a given conveyor speed.
The selected reading mode depends on the number of objects that are simultanously in the
reading field of the CLV during each reading interval. This is independent of the number of
bar codes on the actual object.
Table 6-6 shows an overview of the configurations and ap-
plications.

NoteWhen in slave mode, the CLV receives the trigger signals for the reading pulse (start and
stop) from the OTC 400 via the CAN bus along with (depending on the parameter settings)
the distance information required for focus position switchover. The distance information
can be generated, for example, by the OTC 400 by means of height-control photoelectric
switches or can originate from another CLV.
Immediately after successful reading the CLV sends the reading result (contents of barcode(s)) to the OTC 400 via the CAN bus. The OTC 400 compiles the results received from
all the slaves and evaluates them accordingly before sending them to the host.
OTC 400 Controller:
Besides other function parameterize the following function in the OTC 400:
NoteSICK AG can design and preconfigure more complex omni-portal systems to fulfill the
customer's reading requirements and then provide appropriately trained personnel to
install, test and put these systems into operation.
An overview of the parameterization steps for an example situation is given below (the
overview does not include all available parameterization options).
Prerequisites:
•Max. 20 objects consecutively, simultanously in the reading field.
Example: Omni-directional 3-side reading with groups of CLVs (slaves) and OTC 400
controller (master)
•Minimum object gap between two objects in conveyor direction: 50 mm
•Size of reading field = distance between sensor for beginning/end of object and object
release point parameterized in the OTC 400 (data output)
•Dynamic focus control according to application:
– with OTS height information (distance) via CAN bus for reading from top

Ö FOCUS CONTROL section
ExplanationIn a network configuration, object tracking is carried out by each CLV using an internal con-
tinuous object list. The CLV slave receives the necessary tracking information for the objects
in the reading field (current object number, start and end of object, incremental decoder va
lue) from the OTC 400 via the CAN bus. Depending on the parameter settings, this information can also include distance information for focus control. The position of the CLVs along
the conveyor system must be accurately defined so that the bar code(s), object, and scan
ner can be assigned correctly. A variable tolerance range in the conveyor direction between
two objects (end of one object and start of the next object) enables the reading results to
be assigned to the objects more easily.
Once the information has been read successfully, the CLV sends the reading results (object
number and position of the bar code(s) on the object in the conveyor direction) immediately
to the OTC 400 via the CAN bus. The OTC 400 also collects results with the same name
(identical bar code contents) from each slave to verify them. It then sends the filtered overall
result (for each object relative to the output time in the reading procedure) to the host. The
object enable point (data output) configured in the OTC 400 forms the end of the reading
field. The object enable point configured in the CLV must always be smaller than that in the
OTC 400. The configured focus enable point depends on whether the device is used in a
group and on the arrangement of the CLVs relative to the conveyor system. The focus ena
ble point is the point CLV allows a new focus switchover when the tracked object has passed
this point, even if the number of bar codes to be read has not yet been reached.

•Show CP-limits
For monitoring purposes/trouble shooting:
•I/O monitor in incremental pulse
•Display and edit operating data
•Reading diagnosis
•Monitor host interface
•Auxiliary input
•Self-test
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 (ex
ternal) 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.
Depending of the configuration, the "Result 1" to "Result 4" switching outputs become live
for the predefined pulse length when defined events occur during the reading process (e. g.
Good Read).
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 R
EADING DIAGNOSIS mode for this pur-
pose. 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.

Triggering the reading pulse via the Terminal Emulator:
In the default setting the "Sensor" switching input is the (external) trigger source of the reading pulse. The reading pulse can also be triggered directly via the Terminal Emulator of CLVSetup for test purposes. To do so, a different trigger source must be selected temporarily
in the CLV.
1.Choose DEVICE CONFIGURATION tab.
2.In the READING TRIGGER SOURCE section click the SERIAL INTERFACE option.
3.Perform a download to the CLV.
To do so, click the SERIAL INTERFACE option again with the right mouse button and choose
D
OWNLOAD PARAMETER in the context menu.
CLV-Setup copies the parameter temporary to the CLV.
The serial interface has been activated as the trigger source of the reading pulse and
is ready to receive appropriate commands (until the CLV is switched off).
4.Click in the toolbar.
The Terminal Emulator window is then displayed.
The CLV is in the Reading mode.
5.Click the SW-TRIGGER ON button or press [F7].
CLV-Setup sends a start command to the CLV.
The "Sensor" LED lights up and the red scan line appears.
6.Present the bar code pattern from Fig. 6-1, Page 6-3 to the CLV.
7.Click the SW-TRIGGER OFF button or press [F8].
CLV-Setup sends a stop command to the CLV. The "Sensor" LED is extinguished. The
CLV switches off the laser diode. The CLV displays the reading result in the output win
dow of the Terminal Emulator. The "Read Result" LED lights up for a duration of 100 ms
(default setting).

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 "Result 1" to "Result 4" switching
outputs do not become live in the Percentage evaluation mode.
The Percentage evaluation mode can be called up by choosing VIEW in the menu bar, as a
device function via CLV
Line scanner with oscillating mirror:
480 (interactively), or via the Terminal Emulator.
In the Percent Evaluation mode, the CLV behaves in the following manner:
–in "Oscillating" mode (basic setting: oscillating with a fixed amplitude), the CLV shuts off
oscillation and positions the scan line under the angle CW
deflection angle below 105
°). This position cannot be altered.
= 50 (corresponds to a
–in "One-Shot" mode, the CLV positions the scan line under the angle CW = 50 as well.
–in ”Fixed position” mode, however the scan line’s selected position remains unchanged.
To do so, click the STANDARD option again with the right mouse button and choose
D
OWNLOAD PARAMETER in the context menu.
CLV-Setup copies the parameter temporary to the CLV.
The CLV then uses the standard decoder (until the CLV is switched off).
4.Click in the toolbar.
The Terminal Emulator window is displayed. The CLV is in the Reading mode.
5.In the DEVICE MODE section, choose PERCENTAGE EVALUATION
The dialog box for choosing the distance configuration is then displayed.
6.Choose the appropriate distance configuration that corresponds to the reading
distance of the object (default setting: no. 1, focus position F1 = 1,200 mm (47.3 in)).
7.Confirm the dialog box with OK.
The ”Device Ready” LED is extinguished. The CLV initiates the percentage evaluation
and outputs the reading results continuously.
8.Present the bar code pattern from Fig. 6-1, Page 6-3 and monitor the reading results
in the Terminal Emulator window. An example of this can be seen in Fig. 6-8.
The ”Read Result” LED also provides information on the reading quality:
–The LED is extinguished if reading quality is < 30 %
–The LED blinks twice per second if the reading quality is 30 % to 70 %
–The LED blinks five times per second if the reading quality is 70 % to 90 %
–The LED is lit continuously if the reading quality is > 90 %

The output format of the reading result is the same as that of the Reading mode. Fig. 6-6,
Page 6-27 explains the structure and function of the reading diagnosis data.
The Adjusting mode enables the center of the scan line to be optimally positioned on the
bar code.
Chapter 4.3.3 Help functions for adjusting the CLV, Page 4-9 describes the pro-
cedure for going about this after the Adjusting mode has been called up. The CLV does not
output a reading result in this mode.
The "Result 1" to "Result 4" switching outputs do not
become live.
The Adjusting mode can be called up by choosing VIEW in the menu bar, as a device
function via CLV 480 (interactively), or via the Terminal Emulator.
Line scanner with oscillating mirror:
In the "Adjusting" mode, the CLV behaves in the following manner:
–In "Oscillating" mode (default setting: oscillating with a fixed amplitude), the CLV shuts
of oscillation and positions the scan line under the angle CW
angle of deflection below 105
°). This position cannot be altered.
= 50 (corresponds to an
–In "One-Shot" mode, the CLV positions the scan line under the angle CW = 50
–In "Fixed Position" mode, the scan line’s selected position remains unchanged.
1.Click in the toolbar.
The Terminal Emulator window is then displayed. The CLV is in the Reading mode.
2.In the DEVICE MODE section, choose ADJUSTING MODE.
The "Device Ready" LED is extinguished. The CLV cancels the Reading mode and
blanks the red 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.
6.5.4Show CP-limits
In this mode, the CLV blanks certain parts of the red scan line so that any limit values defined
for the active evaluation range of the scan line can be checked directly during parameteri
zation. 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 M
C
ODE POSITION and MAXIMUM CODE POSITION in the DISTANCE CONFIGURATIONS tab of the READING
C
ONFIGURATION tab. The CLV does not output a reading result in this mode.
INIMUM
Show CP-limits enables you to check whether the restriction has been adapted for each active distance configuration ("Christmas tree" effect)
Show CP-limits can be called up via VIEW in the menu bar, as a device function via CLV 480
(interactively), or via the Terminal Emulator.
Line scanner with oscillating mirror:
In "Show CP-limits" mode, the CLV behaves in the following manner:
–in "Oscillating" mode (default setting: oscillating with a fixed amplitude), the CLV shuts
off oscillation and positions the scan line under the angle CW
angle of deflection below 105
°). This position cannot be altered.
= 50 (corresponds to an
–in "One-Shot" mode, the CLV positions the scan line under the angle CW = 50.
–in "Fixed Position" mode, the scan line’s selected position remains unchanged.
The CLV blanks the scan line alternately as of the set value for CP
