3. System requirements
4. Laser rotection
Laser radiation!
The radiation emitted by the laser diode (red or IR light) on the CLV 10 is harmful to
the human eye. For this reason, do not look directly into the laser beam.
Opening the housing while the device is in operation does not prevent the laser diode
from being activated by the reading pulse.
The maximum output power of the laser beam at the reading window is 1 . 2 mW.
The CLV, therefore, is assigned to protection class 2.
Laser radiation, do not stare into the beam, class 2 laser roduct.
Max. out ut radiation: 1 . 2 mW (223 µµ
µµ
µs), emitted wavelength: 670 nm

7. Function of the LEDs
The LED function indicators 7 are located on the rear, narrow side of the device (Fig. 1).
LED Color Function
Device Ready green Indicates that the the CLV is ready (Reading mode). Lights up when the device is switched on, after
the self-test has been successfully completed and when the wait time for teach-in mode has expired.
The LED extinguishes when the device is switched to a different operating mode.
Result green Function depends on the operating mode of the scanner:
•In Reading Mode or Teach-in Mode, the LED indicates a successful read (good read).
If the match code comparison is activated, it lights up if the bar code read matches the specified
match code(s).
The LED lights up constantly until the start of the next reading pulse
•In Percentage Evaluation with 100 scans per reading interval, the LED indicates the trend in the
read quality as follows:
LED off good read rate < 30%
LED blinks (frequency 2 Hz) good read rate 30%...70%
LED blinks (frequency 5 Hz) good read rate 70% ... 90%
LED lights up constantly good read rate > 90%
•The LED lights up briefly when set to AutoSetup before it starts to scan the presented bar code
Laser On green Lights up when the laser diode is activated for reading the bar code.
The laser diode is activated and deactivated by the reading pulse.
The laser diode is activated constantly in Percentage Evaluation and Free-running modes.
In Reflector Polling pulse mode, it is activated in accordance with the scanning frequency at every
20th scan (LED flickers).
The scan line(s) are dimmed (with red-light scanner only)

8. 5 Connecting the interfaces
All of the interfaces are routed via the 15-pin D Sub HD connector À (Table 3).
8. 5. 1 Connecting the host interface
The CLV is equipped with two host interfaces (RS 232 and RS 22/ 85). One of
these must be selected for data communication with the host/PC. If the RS 232
interface is not connected to the host, it can be used exclusively to monitor data
traffic on the parallel RS 22/ 82 interface.
TIP:
The internal modules of the CLV may be damaged irreparably if the data interface
is connected incorreclty.
ØConnect the host interface of the CLV to the host in accordance with the EMC
requirements using shielded cables(Fig. )
ØTo prevent interference, do not lay the data cables over a long distance parallel

8. 5. 2 Connecting the functional interfaces
Sensor 1 switching in ut
In order to trigger a reading process, the CLV requires a suitable clock pulse in
Reading mode that signals the presence of a conveyor object in the reading field.
The clock pulse generates the reading interval (time window for evaluation) internally
in the CLV. In the default setting, the reading pulse is supplied by means of internal,
continuous reflector polling (see Section 9.2).
If an external sensor (e.g. photoelectric switch, switch) is to notify the CLV of the
presence of a conveyor object, the following steps must be performed:
ØConnect the sensor to the CLV as shown in Fig. 5

ØProcedure for teaching in match code 1
Prerequisite: CLV is in Reading mode and the current parameter set (if
application-specific) is stored permanently.
Notes:
1. In order to replace the match code taught in in this way with a different match
code, you can repeat steps 3 to 6 without having to switch off the CLV.
2. If match code 1 is set using the teach-in method, it must not be modified with the
user interface (or command strings) until the CLV is switched off again. The
methods used to set the match code cannot be mixed. This does not affect
match code 2.
Result 1 to Result 3 switching out uts
The three outputs (Fig. 7) can each be assigned different result functions. When the
associated result occurs, the corresponding output becomes live for the selected
pulse duration at the end of the reading interval. The pulse duration can be set
separately for each output.
Ste Action Res onse from CLV1)
1 Switch off CLV –
2 Close switch S and CLV switches to Reading mode and activates
switch on CLV again teach-in mode for the match code.
3 Open switch S CLV in teach-in mode and searches match
code.
Position match code at appropriate –
distance (see 16. Reading field
diagrams)
5 Trigger set reading pulse CLV reads the match code.
The Result LED lights up to confirm
successful read (good read; default setting).
Beeper emits a short acoustic signal.
6 Close switch S again CLV stores the match code and its code type
in the valid parameter set and permanently
in the EEPROM.
From this point on, it compares each match
code read with the match code taught in.

9. 1 Securing the CLV
The two fastening threads (2, Fig. 1) on the bottom, narrow side of the housing are
used to secure the CLV. The thread dimensions are shown in Section18. Dimensioned
diagrams.
9. Assembly
Mounting accessories
The CLV can be easily secured to the base to suit the relevant application using one
of the two optional mounting brackets (Fig. 8). This facilitates precise adjustment in
two planes. The dimensions of these brackets are shown in Section 18.
Dimensioned drawings. The elongated holes in the brackets allow the CLV to be
adjusted with a freedom of rotation of approx. ± 15°.
Risk of damage to the housing
The max. depth of engagement of the two M tapped blind holes is 6 mm from
the housing surface. Do not exceed this depth.
Fig. 8. Mounting example: securing the CLV using the mounting bracket (accessory)
Aligning the CLV with the bar code
The alignment between the CLV and line or raster scanner depends on the
application. The basic alignment between the two scanning methods and the
conveyor object is shown in Fig. 9.

Reading angle and distance
When mounting the device, ensure that all of the possible reading angles at which the
bar code can be positioned relative to the scan line are taken into account. Fig. 10
shows this using a line scanner as an example. The reading window and code should
be almost parallel, whereby total surface reflection (see below) should be avoided.

Table 10
When selecting the mounting location for the device, the limit values of the reading
range for the selected bar code resolution and the useful aperture angle (max. 60°
with front light emission) must be taken into account. See also Section 16. Reading
field diagrams.
Avoiding surface reflection
If the reading beam strikes the surface of the bar code vertically, reflection
interference may be caused when the returned light is received.
ØMount the CLV with front light emission (a) in such a way that the scan line(s) strike
the bar code at an angle less than approx. 15° from the vertical reference (Fig. 11).
ØThe CLV with lateral light emission (b) must be mounted flush so that the scan line
is emitted at an angle less than 105° relative to the housing.

Count direction of code osition CP
The CLV determines the position of the bar code within the scan line (CP value),
Fig. 12. This can be used to separate several identical bar codes (identical code
type, length and content) and output them accordingly.

9. 2 Mounting the olling reflector
In order to generate the reading pulse automatically using internal reflector polling
(default setting), one of the two polling reflectors supplied (special bar code) must
be mounted opposite the CLV behind the conveyor section.
ØNote the maximum ranges of the two reflectors (Fig. 13)
ØMount the polling reflector (self-adhesive) opposite the CLV (in the alignment line)
in such a way that the CLV can view the reflector freely in the gaps between the
conveyor objects and can scan it reliably (center of scan line).
The scan line of the CLV should scan the code lines of the polling reflector
vertically.
ØCheck the polling reflector installation for 100% read quality using the
Percentage Evaluation mode in the TERMINAL option of the user interface (see
Section 10.6). The CLV outputs the code content of the polling reflector and
signals REPO as the code type.
Function of reflector olling
In Reflector Polling pulse mode, the CLV activates the laser diode with every 20th
scan and checks whether it detects the reflector:
- if the reflector is still detected, the CLV repeates the procedure after the 20th
scan

- the CLV starts the reading interval when the reflector is concealed by a conveyor
object in the reading field. The interval ends when the CLV detects the reflector
again. It then repeats the procedure above.
Notes:
This clock mode (max. delay approx. 100 ms at a scan rate of 200 Hz) is only
suitable for applications that are not critical with respect to time.
When the CLV is switched on, it must be able to detect the polling reflector. The first
reading interval can only start if this is the case.
In Reading mode, the CLV does not output the content of the polling reflector.
9. 3 Mounting the external reading ulse sensor (alternative)
If an external sensor (e.g. photoelectric switch) is used to generate the reading
pulse, it must be mounted on the CLV in a suitable manner. Ensure that objects of
different size carrying bar codes trigger the internal reading pulse in such a way that
sufficient time is provided to read the code. Examples of the CLV with line scanner
are provided in Fig. 1 .

The CLV must not be connected with the PC (offline mode). The default setting
values are stored permanently in the user interface and on the CLV. The parameter
values are displayed in the menu options of the individual configuration cards. You
can print out the entire default settings by clicking the icon.
Note:
When you make changes to the default settings, we recommend that you save them
as a different configuration file (*.scl) on the PC using the SAVE AS option in the
program.
IMPORTANT
Tem orary host interface defaults
In order to allow you to access the CLV with the PC at any time, you can set the
host interface temporarily to the default setting (9600 bits/s, 8 data bits/1 stop
bit, no parity) using the profile bar codes:
ØPresent rofile bar code no. 11 to the CLV in Reading mode and su ly
an a ro riate clock ulse to the device.
The CLV resets the host interface to the default values and confirms this with
an acoustic signal from the beeper. It then resumes Reading mode
immediately
ØTo restore the revious host interface configuration on the CLV, resent
rofile bar code no. 12 to the CLV.
The CLV confirms that the values have been reset with an acoustic signal and
resumes Reading mode immediately.
Alternative:
ØSwitch the CLV off and on again to return to the original configuration
10. 3 Profile rogramming
Profile programming uses special bar codes to change the CLV parameters directly
without having to connect the PC with user interface. The profile bar codes are
simply presented to the CLV. The device then transfers the coded parameter values
to the current parameter set and stores them permanently. The changes remain valid
after the programming procedure has been completed and affect the further reading
procedure. The CLV waits 10 s after each profile bar code. If no more profile bar
codes are presented, it resumes standard Reading mode and confirms with two
consecutive acoustic signals.
Since the CLV overwrites important parameter values (e.g. those generated with
AutoSetup) without requiring confirmation, we recommend that you upload the valid
parameter set to the PC and store it as a configuration file (*.scl) with the SAVE AS
option in the user menu before you change the parameter settings.
You can program the CLV at any time in Reading mode. Alternatively, you can present
one or more profile bar codes to the CLV for reading within 5 seconds after the
device has been switched on and the self-test has been completed (free-running).
The CLV does not output any reading results during profile programming and does
not respond to an external reading pulse.

CLV 1x Bar Code Scanner
Printed rofile bar codes
A total of 12 selected profile bar codes are provided on the „Configuration Profiles
for CLV 1x Bar Code Scanner“ card to make important changes (from the default
settings or the application-specific parameter set respectively). By folding the
individual segments of the card, you can ensure that the CLV only reads the
required profile bar code. The function of the profile bar codes is explained in
Table 12.
If you cannot access the host interface of the CLV from the “CLV Setup” user
interface (e.g. baud rate or data format not in line with default settings), the profile
bar code no. 11 can be used temporarily to set the CLV to the default settings
(host interface). To reset the system, use profile bar code no. 12 or switch off CLV.
IMPORTANT
