CLV 45x Bar Code Scanner

Installation steps (overview)

Reading trigger via “Sensor 1“ switching input (default setting)

1. Check whether the delivery is complete.

2. Install the CLV in the reading station and align to the object with bar code.

3. Install the AMV/S 40 connection module and cover the terminal designations in the

connection area.

4. Connect the CLV to the AMV/S 40 connection module.

5. Install the reading-pulse sensor.

6. Connect the reading-pulse sensor to the "Sensor 1" switching input in the AMV/S 40.

7. Install the sensor for the distance detection.

8. Connect the distance sensor to the "Sensor 2" switching input in the AMV/S 40.

9. Connect the host to the "Host interface" in the AMV/S 40.

Adapt the AMV/S 40 to the host interface type of the CLV.

10. Switch on the supply voltage of the AMV/S 40.

After the CLV has been started the "Device Ready" LED lights up. The beeper signals that Reading mode has been started by means of two consecutive sounds.

Line scanner with oscillating mirror:

In reading mode the CLV deflects the scan line in the default setting with a frequency of 1 Hz around the position CW = 50 at a maximum angle of ±20°.

11. Switch on the PC and start Windows

12. Install the supplied "CLV-Setup" user software, "CLV-Setup Help" online help and, if re-

quired, "I-ViewPro

" HTML browser from the CD-ROM on the PC.

13. Connect the PC to the terminal interface of the CLV.

To this purpose connect the PC via the RS-232 data connection cable to the "Service" plug in the AMV/S 40.

14. Start the "CLV-Setup" software.

CLV-Setup starts the communication with the CLV and copies the parameter record of the CLV by means of an upload. The parameter record is displayed in the tab cards.

15. Carry out a test read run with a test bar code specimen (pulse the CLV correspondingly).

Display the read result in the terminal emulator of CLV-Setup.

16. Configure the CLV for the application by means of the setting options on the tab cards

in CLV-Setup. Copy the modified parameter record temporarily to the CLV per download.

Do not

switch off the supply voltage of the AMV/S 40 (of the CLV).

17. Test the application under real conditions.

18. Check the correct data transfer of the CLV to the host.

19. If necessary, correct and optimize the set parameter values.

Copy the parameter record

permanently

20. Save the parameter record as a configuration file "*.scl" in CLV-Setup!

(minimum requirement Windows 95TM).

to the CLV per download.

2-1

Chapter 2 Operating Instructions

Safety information

CLV 45x Bar Code Scanner

Danger of injury through electrical current!

The AMS 40 connection module (accessory) for the CLV is connected to 230 V 50 Hz or 115 V AC 50/60 Hz supply voltage, depending on the type.

Observe the common safety regulations when working on electrical installations.

Laser radiation may cause damage to your eyes! The CLV operates with a Class 2 red-light laser. The retina can be damaged if you look

too long into the laser beam.

Never look directly into the laser beam (comparable with sunlight).

Do not point the laser beam at persons.

When mounting and aligning the CLV take the reflection of the laser beam against reflecting surfaces into account.

Do not open the housing. (Opening does not interrupt activation of the laser diode by the reading pulsing.)

Observe the laser protection specifications in accordance with DIN EN 60825-1 (latest version).

Laser performance

The laser operates with a wavelength of λ= 650 nm (visible red light). The power output of the laser beam amounts to a max. of 3.5 mW at the reading window. The emitted radiation is not dangerous to the human skin.

Laser warning labels

The laser warning labels relevant for Europe (

Fig. 2-1

) are located at the following points at

the CLV:

•

At the line scanner the British/US version of the laser warning symbol and the laser warning are located next to the front-end reading window on the side surface (refer to

Fig. 3-1, Page 3-3

•

At the line scanner with oscillating mirror the British/US version of the laser warning sym-

bol and the laser warning are located on the side surface opposite the reading window (refer to

Fig. 3-2, Page 3-4

2-2

Fig. 2-1: Laser warning label attached to the CLV (valid for Europe)

Note The scope of delivery includes a set of laser warnings in German/US English and French/US

English. These can be stuck over the British/US warning.

If the CLV is installed in a machine/casing in such a manner that the laser warning labels of the device is concealed, further warning labels (not included in the scope of delivery) must be attached on the machine next to the aperture of the laser beam!

Operating Instructions Chapter 2

CLV 45x Bar Code Scanner

Safety information

Internal protective circuits

The CLV has monitoring circuits which shut off the laser diode when irregularities occur in the beam generation.

The switching on and off of the laser diode during the reading process is controlled by the reading pulsing (pulse source).

In the pulsing types "Sensor input" and "Serial interface" a timer (laser timeout) switches off the laser diode automatically 10 min (default setting) after the beginning of a lasting reading pulse during reading mode. However it does not terminate the reading pulse. CLV outputs the following message via the terminal interface:

"Laser safety timeout"

The reading pulse has to be terminated by means of a corresponding pulse signal. The next reading pulse re-activates the laser diode.

The laser timeout can be set in the range of 1 min ... 25 h or de-activated (refer to

Table 6-7, Page 6-12

The laser diode is always active in reading mode in the operating modes "Percentage evaluation", "Adjusting mode", "Show CP limits" and "Auto setup" as well as in the "free-running" pulsing type.

2.4 Quick Stop and Quick Restart

2.4.1 Switching off the CLV

Switch off the supply voltage or pull off the cable plug of the CLV from the connection module.

At most the following may be lost:

•

The application-specific parameter record, if it was only saved temporarily in the CLV

•

The last reading result

•

Day operating data (operating hours counter, trigger count, number of good reads, maximum duration trigger, minimum duration trigger, average identification quality)

2.4.2 Switching on the CLV again

Switch on the supply voltage or pin up again the cable plug of the CLV to the connection module. The CLV restarts operation with the parameter record last saved permanently and re- sets the day operating data.

Chapter 2 Operating Instructions

Safety information

CLV 45x Bar Code Scanner

2.5 Environmental information

The CLV is designed so that it harms the environment as little as possible. It does not have any materials using silicone and is therefore not a source of faults for, for example, coating wetting in paint shops.

2.5.1 Power requirement

The power requirement is low.

•

The line scanner consumes a max. of 6 W

•

The line scanner with oscillating mirror consumes a max. of 7.2 W

The values each correspond to operation with open-circuited switching outputs.

2.5.2 Disposal after final removal from service

Dispose of unusable or irreparable devices in accordance with the respective state regulations on waste disposal in a manner compatible with the environment. The design of the CLV allows it to be separated into recyclable secondary raw materials and hazardous waste (electronic scrap). Refer to

Chapter 7.3 Disposal, Page 7-2

At present SICK AG does not take back devices which have become unusable or irreparable.

Product description

3.2 Working method of the device

The CLV detects bar codes by means of a scan line and decodes them. The CLV transmits the data via the main data interface (serial host interface) to a host/PC for further processing.

"Terminal"

"Sensor 1"

"Sensor 2"

"Host"

"Result 1"

"Result 2"

Fig. 3-3: Block diagram: Functions of the CLV

The CLV provides two decoders for decoding:

•

The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding bar codes with a small "aspect ratio" (ratio of the code height to the code length), for bar codes with damaged or soiled printing image as well as for reading bar codes under a strong tilt (azimuth angle)

•

The proven standard decoder of the CLV series

The CLV derives useful data for diagnostics from the reading processes, which can also be transferred to the host. In addition it carries retrievable operating data. The quality of the reading can be checked in the "Percentage evaluation" operating mode.

The CLV requires suitable triggering in order to start a reading process when there is an object in the reading area. This results in a time window ("reading interval") for the reading process being opened in the CLV. In the default setting triggering is carried out by means of an external reading pulse sensor. Alternative trigger sources are free-running operation or a command via the host interface.

Four LED status displays inform optically on the current operating state. A beeper (buzzer) signals the status of the read result acoustically. In the default setting the Good Read function is selected to this purpose.

In the case of external triggering by a sensor the "Sensor 1" switching input signals the CLV when it is to start a reading. The "Sensor 2" switching input is used to change over the focal position. It can be used alternatively e. g. for the teach-in of a match code. The switching outputs "Result 1" and "Result 2" can have various output functions of the result status assigned to them and control external devices, such as a PLC.

The CLV is operated and configured via the auxiliary data interface (serial terminal interface) by means of the user interface of the "CLV-Setup" PC software or via the host interface/ terminal interface by means of command strings.

System, warning and error messages provide support in setting up and searching for errors during starting up and reading operation.

The trigger source for the changeover with a maximum of 2 st ages is a s ignal at t he "Se nsor 2 " swi tch ing inp ut. For th e cha ngeov er w ith a m axim um of 8 stages a command at the host interface interface or the integrated timer (e. g. for search runs). At the line scanner with oscillating mirror additionally the oscillating mirror inversion points of the two-sided displacement. The distance configurations are assigned to the changeover sequence by means of a programmable assignment table.

3.2.2 Variants of the scanning process

Line scanner

Generates one scan line. The reading area height (for evaluating the usable length of the scan line) depends on the reading distance because of the V principle of the beam deflection.

Line scanner with oscillating mirror

The oscillating mirror additionally deflects the scan line vertically to the scanning direction to both sides at a low oscillating frequency. This means that the CLV can also scan larger areas or ranges for bar codes. The reading field height (for evaluating the usable length of the scan line) depends on the reading distance because of the V principle of the beam deflection.

In addition to parking (fixed position) and the simple deflection with a maximum deflection width, optimized function runs of the oscillating mirror are also possible:

•

Oscillation with variable deflection per distance configuration

•

One-Shot: Single defined deflection per reading pulse (forward and return).

The effective aperture angle α amounts for the CLV 450 to a max. of 50°, for the CLV 451 to a max. of 55° at both scanning processes. Due to the V principle of the beam deflection the reading field height (for evaluating the usable length of the scan line) depends on the reading distance.

CLV 45x Bar Code Scanner

Avoiding surface reflections

If the light of the scan line falls exactly vertically on the surface of the bar code, disturbing reflections can occur when the reflected light is received. In order to avoid this effect the CLV must be installed so that the emitted light is tilted relative to the perpendicular.

Fig. 4-8: Avoiding surface reflections: Angle between the emitted light and the bar code (tilted

away from the perpendicular)

At the line scanner with oscillating mirror the laser beam is emitted during oscillating mode at an angle of 105° to the housing during the pass through the neutral position CW = 50). The device can only be mounted flush to the edge at the transport unit if the deflection ranges of the oscillating mirror is small. Otherwise the device also has to be mounted at an angle of inclination of 15 in order to attain symmetrical deflection ranges.

4.2.8 Counting direction of the code position CP and of the code angle CW

Explanation The CLV can scan and decode several bar codes during every reading.

In the process it determines the local reading diagnostic data for each bar code:

•

The position (CP value) of the bar code center within the scan line

•

In addition in case of a scanning process with oscillating mirror the deflection angle of the scan line (CW value) under which the bar code center is detected

Fig. 4-9

shows the counting direction of the code position and of the code angle.

The determination of the two data allow identical bar codes (code type, code length and data contents) to be separated as well as the local assignment of the bar code data in the read result to its position on the object.

7. Tighten the screws slightly.

8. Adjust the CLV as described in

4.3.2 Adjusting the CLV

The "Percentage evaluation" operating mode supports adjustment of the CLV. In this operating mode the CLV displays the quality of the readings of bar codes which are placed statically into the reading area of the CLV (no transport movement of the object). The CLV carries out 100 scans each free running and evaluates the reading quality statically. It outputs the read results continuously every 2 s via the terminal interface.

The display behavior of the "Result" LED provides additional optical information on the reading quality:

•

If the LED does not light up, the CLV cannot read the bar code (reading quality < 30 %).

•

If the LED flashes, the CLV can only read the bar code badly (reading quality 30 % ... 90 %).

•

If the LED lights up continuously, the CLV is aligned optimally (reading quality > 90 %). In the default setting the scanning frequency amounts to 600 Hz.

1. Connect the CLV to the AMV/S 40 connection module and switch on the supply voltage of the module (refer to After the start the CLV confirms the successful self-test with a beeper sound and shortly afterwards starting of the reading mode is signaled by two consecutive sounds. The "Device Ready" LED lights up.

Chapter 6.5.2 Percentage evaluation, Page 6-21

During all the further steps observe the behavior of the reading quality (as a %)!

Line scanner with oscillating mirror:

In the percentage 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 = 50 (corresponding to

an angle of deflection of 105°). This position cannot be altered. – 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.

Carrying out fine adjustment:

11. Align the CLV so that the angle between the scan line and the bar code bars amounts to approximately 90°.

12. In order to avoid disturbing reflections, turn the CLV out of the perpendicular so that the emitted light impacts on the bar code at an angle of approx. 105° (line scanner)

14. Manually guide objects with bar codes successively under realistic conditions into the reading area of the CLV and check the read result. If the objects move loosely, check several different positions (angles) of the bar code and ensure that the limits of the permitted reading angle is not exceeded.

15. Adjust the CLV so the "Good Read" rate lies between 70 ... 100 %. In case of different object sizes per defined reading range (distance configuration) check the selected focal position and if necessary correct the parameterization (refer

4.4.1 Installing the AMV/S 40 connection module

Terminal assignment

The terminal assignment printed on the board in the connection area of the AMV/S 40 is valid for the device types CLV 21x/22x/41x. If a CLV 45x is connected via the 15-pin socket, the resulting terminal assignment deviates from the printed terminal assignment. This also applies for the representation in the wiring diagram in the housing cover.

Danger of damage to the CLV and external I/O devices!

The deviating display of the terminal strip assignment means that external devices (e. g. PC) can be connected incorrectly to the CLV and possibly damaged.

Before carrying out the installation stick the two enclosed labels for the CLV 43x/44x (also valid for CLV 45x) over the printed assignments in the connection area as well as the wiring diagram in the housing cover.

1. Apply the larger label in the connection area before the terminal strips so that the Terminals 2 and the Terminals 18 agree.

If the CLV is triggered by means of an external reading-pulse sensor, the sensor is installed near the CLV. In the default setting the "Sensor 1" switching input is selected as the trigger source for this triggering type.

Fig. 4-12

shows two examples of the installation site of a photoelectric reflex switch. This depends on the distance a of the bar codes to the front object edge. Depending on the application the sensor is to be installed so that bar codes on objects of different sizes can be read completely during the time window of the evaluation (reading interval).

4.4.3 Mounting the sensor for detecting the object distance

The CLV provides a dynamic focal position changeover for serial covering of a large reading range. To this purpose a changeover with a maximum of 2 stages can be implemented via the "Sensor 2" switching input.

Fig. 4-13

shows an example for reading from above. A photoelectric reflex switch is, for example, used for the detection of the object distance. This application is suitable for such object sizes whose difference can be covered by 2 changeover ranges. The distance sensor is to be positioned so that these object sizes are classified clearly and two overlapping reading ranges arise which can be formed with the depths of field of the CLV. The two distance configurations (reading ranges) are assigned from a maximum of 8 configurations by means of the internal assignment table (combinatorics). In the default setting the "Sensor 2" switching input is selected for the focal position changeover.

The two switching outputs can have various functions for the result status output assigned independently of each other. If the assigned event occurs in a reading process, the corresponding switching output becomes live for the selected pulse duration after the end of the reading pulse. The pulse duration is the same for both outputs.

The "Result" LED is coupled to the "Result 2" output and lights up in the "Reading mode" operating mode for the set pulse duration and selected function of the result status display (default setting: Good Read, 100 ms).

Operation

6.3 Quick-Start

A PC does not have to be connected if the CLV is operated with the factory default setting.

6.3.1 Starting up the line scanner/line scanner with oscillating mirror with the factory default setting

1. Connect the CLV to the SICK AMV/S 40 connection module.

2. Connect the reading-pulse sensor (e. g. photoelectric reflex switch or switch) to the

"Sensor 1" switching input of the CLV via the AMV/S 40 (refer to

the "Sensor 1" switching input, Page 5-7

3. Switch on the supply voltage of the AMV/S 40.

Line scanner with oscillating mirror:

In reading mode the CLV deflects the scan line in the default setting with a frequency of 1 Hz around the position CW = 50 at a maximum angle of ± 20°. 50 CW corresponds to a light emission under 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 scan line appears.

5. Present the bar code pattern in

Fig. 6-2, Page 6-4

tern in

Fig. 6-1

to the CLV 450 respectively the bar code pat-

at the reading distance specified in

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 off the laser diode. The CLV confirms that the bar code was read successfully by outputting an acoustic signal via the beeper. The "Result" LED lights up for duration of 100 ms. The "Result 2"

("Good Read") output switches for the duration of 100 ms. The CLV can now be operated with the factory default setting. The device can be switched off without the configuration data being lost as no changes have

been made to the parameter record.

6.4 Configuration (parameterizing)

The CLV is configured locally to suit the local reading situation. This ensures that the reading, evaluation and output properties can be parameterized as required. The initial base is the factory default setting or an application-specific parameter record already created for the CLV.

The CLV supports four different configuration methods:

•

Configuration by means of the "CLV-Setup" PC software and the CLV assistant (parameter values are set via the serial interface)

•

Configuration by means of Auto Setup (reading and code configurations for one bar code are adapted automatically via the optical interface (reading window)) (refer to

•

Configuration by means of Profile bar codes (parameter values are set via the optical interface (reading window)) (refer to

•

Configuration by means of command strings (parameter values are set via the serial interface) (refer to

The CLV does not output any read results in parameterization mode with the exception of Auto Setup.

from the CLV. This process is designated as uploading ("Upload from CLV"). During it CLVSetup always loads a complete copy of the current parameter record from CLV. This remains unchanged there until it is overwritten by the CLV-Setup. On the other hand, the pop-up menu (right-hand mouse button) is used to load only the parameter currently being edited from the RAM of the CLV ("Upload parameter").

Changes made to the current parameter record in CLV-Setup do not take effect until the parameter record has been transferred to the CLV. CLV-Setup always loads a copy of the complete parameter record to the CLV, so that all the previous parameter values are overwritten in the CLV. Transferring and saving the parameter values in the CLV is designated as down- loading ("Download to CLV"). On the other hand, the pop-up menu (right-hand mouse button) is used to load only the parameter currently being edited temporarily into the RAM of the CLV ("Download parameter").

Loading a complete parameter record from the CLV (uploading)

Click on in the toolbar. CLV-Setup loads the current CLV parameter record from the RAM of the CLV to its database and displays the values in the tab cards. The "Device Ready" LED is extinguished during the transfer process.

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 E

Explanation of oscillating mirror functions

"Oscillating with fixed amplitude" operating mode

The oscillating mirror deflects the scan line up to the maximum deflection range of

40 CW (corresponding to ± 20°).

Chapter 6 Operating Instructions

Operation

CLV 45x Bar Code Scanner

"Oscillating with Variable Amplitude" operating mode

The deflection range can be parameterized separately for each of the maximum of 8 distance configurations/focal positions. The limitation of the deflection range for fast applications ensure that the scan line only sweeps areas that contain bar codes during the time available. At the same time this allows an almost constant scan line density on the object.

shows the application at a reading from above.

Operation

"Fixed position" operating mode

The CLV parks the oscillating mirror at the desired position. 10 CW correspond to –20°, and 90 CW to +20° (

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.

"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. 6-5

shows an example for the application in 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.

Chapter 10.7.2 Calculating the start position and mirror speed for the forward and return phase of the One-Shot function, Page 10-37

veyor speed. Possible trigger sources for One-Shot:

6.4.4 Configuring the CLV with Auto Setup

Auto Setup enables the reading and code configurations of the CLV to be adapted automatically to the existing read situation. The following conditions must be fulfilled for the execution:

•

One bar code (code type, code length)

•

Fixed reading distance

•

No transport movement (static reading)

The CLV determines the code type, code length, the optimum focal position and the most favorable scanning rate for the bar code presented. This takes place in Free running mode with the standard decoder even if the SMART decoder may have been preselected beforehand for the Reading mode. Once Auto Setup has been completed successfully, the CLV copies the parameter values determined to its parameter record. All other code types and code lengths are disabled for further readings. If Auto Setup was not completed successfully, the parameter record is not changed. In Auto Setup the CLV does not read a Pharmacode or an EAN or UPC attachments. It does not react to an external reading pulse.

Auto Setup can be activated in three different ways in the CLV:

•

By means of the CLV-Setup user interface

•

By presenting Profile bar code No. 10 on the card supplied to the optical interface (reading window)

Chapter 10.5.1 Activate Auto Setup with Profile bar code, Page 10-28

See

•

By means of a command string (via the serial interface)

Chapter 10.6 Configuring the CLV with command strings, Page 10-33

See

While Auto Setup is running, the CLV outputs the step-by-step changes made to the parameter values in the search mode as well as the determined diagnostic data via the terminal interface in the form of a list. The list can be displayed, for example, in the terminal emulator of CLV-Setup. Once Auto Setup has been completed, appropriate error messages are output for diagnosed malfunctions in the event of a no read.

6-14

Explanation Auto Setup procedure

1. The CLV moves across the entire focal position range in steps of 25 mm from F = 200 mm to 1 200 mm at a scanning frequency of 600 Hz. It evaluates the reading quality of 100 scans at each focal position.

2. When it reaches the part of the focal position range with the highest reading quality, the CLV determines 5 positions from which it then mathematically calculates the maximum reading quality and the focal position.

3. The CLV approaches this calculated focal position and performs a verification read.

4. If the reading quality is >75 %, the CLV increases its scanning frequency in steps of 100 Hz, starting at 400 Hz, up to 1 000 Hz. Once again, it evaluates the reading quality

Operating Instructions Chapter 6

CLV 45x Bar Code Scanner

Operation

of 100 scans for each step. If the reading quality is lower, the CLV changes further parameter values internally.

5. The CLV performs verification reads around the scanning frequency with the highest reading quality at a scanning frequency lying 50 Hz above and 50 Hz below it.

6. It then copies the optimum scanning frequency, the focal position, as well as the code type and code length in its parameter record.

Activating Auto Setup by means of the CLV-Setup user interface

In CLV-Setup, Auto Setup can be started by selecting the appropriate menu path, via the terminal emulator or as an executable device function (interactively). We recommend starting the Auto Setup by means of the terminal emulator since the progress display is better.

Preparing Auto Setup

6.5.2 Percentage evaluation

In the Percentage evaluation mode, the quality is assessed of the readings of bar codes which are placed statically into the reading area of the CLV (no transport movement of the object).

The CLV performs 100 scans in the Free-running mode and evaluates the reading quality. It outputs the read results continuously every 2 s via the terminal interface. The read re- sults 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 V

in the menu bar or via the

terminal emulator.

Line scanner with oscillating mirror:

In the Percentage 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 = 50 (corresponding to an angle of deflection of 105°). This position cannot be altered.

– 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.

Maintenance

7.1 Maintenance during operation

A clean reading window is required to maintain the full reading performance of the CLV. It is therefore advisable to check the reading window regularly for dirt, in particular in rough

operating environments (dust, abrasion, moisture, fingerprints).

Laser radiation may cause damage to your eyes!

The CLV operates with a Class 2 red-light laser. The retina can be damaged if you look too long into the laser beam.

Never look directly into the laser beam (comparable with sunlight).

Switch off the device for the duration of cleaning.

Never look into the reading window while the device is in operation.

Damage to the reading window!

The reading window consists of glass. The reading performance is reduced by scratches and streaks on the reading window.

Use a mild detergent without power admixture.

Avoid scratching and scouring movements on the reading window.

Cleaning the reading window

Clean the reading window at regular intervals with a mild detergent without powder admixture, for example an anti-static window liquid detergent. faces to be cleaned.

Use a soft lintfree cloth for cleaning.

If required, also clean the LEDs of the device rear.

Cleaning the further optically effective surfaces:

In the case of external reading cycle generation and/or object height detection with sensors (e. g. reflection photoelectric switches) clean their optically effective surfaces

Fig. 7-2

(

Fig. 7-2: Cleaning the external optical sensors (reading clock generator, object height detection)

). Dirt and impurity can cause faulty switching performance.

7.2 Maintenance

The CLV operates maintenance-free. Its self-monitoring functions allow long, trouble-free operation.

The CLV outputs device and function errors in the form of messages via the terminal interface. As far as they exist in clear text, they are displayed on the screen of the PC in extended mode of the terminal emulator of the CLV-Setup user interface. Further errors are displayed as a numerical combination in the 4th field from the bottom left in the status bar (Refer to

Chapter 8.3 Error messages, Page 8-2).

7.3 Disposal

After having shut down unusable or irreparable devices dispose of them in a manner which does not damage the environment.

1. Observe the country-specific guidelines on waste disposal.

2. Dismantle the CLV housing.

3. Remove the electronic modules and connection cable.

4. Remove the glass pane of the reading window and dispose of the glass as waste glass.

5. Dispose of the chassis frame and cover in the disposal for zinc diecasting.

6. Dispose of electronic modules and connection cables as hazardous waste.

At present SICK AG does not take back devices which have become unusable or irreparable.

Troubleshooting

8.1 Overview of the possible errors and malfunctions

8.1.1 Mounting errors

•

8.1.2 Faults during the electrical installation

•

8.1.3 Parameterization errors

•

CLV aligned incorrectly to the object with the bar code (e. g. blanking) Reading-pulse sensor positioned incorrectly With focal position changeover: Sensor for object height detection positioned

incorrectly

Interfaces on the CLV wired incorrectly (wiring error in AMV/S 40) Host interface on AMV/S 40 configured incorrectly

Functions not adjusted to local conditions, e. g. communication parameters on the host interface are set incorrectly

Technical limits of the device exceeded, e. g. relationship between the scanning frequency and the reading distance

8.1.4 Faults during operation

•

Laser timeout for laser diode expired

•

Device fault (hardware/software)

8.2 Monitoring error and fault signs

The CLV is self-monitoring:

•

After the supply voltage has been switched on, the CLV automatically carries out a selftest, in which it checks important hardware components, before it is initialized (parameter record loaded and device functions initialized). The self-test can be repeated at any time after the reading mode has been canceled. For the call-up refer to the

•

If the CLV detects an error during the self-test/self-diagnosis, it outputs the error status ST = 3 via the host interface. Prerequisite: The error status is enabled for transfer. In the default setting transfer is disabled. The CLV displays the diagnosed error in code form as a numerical combination in the 4th field from the bottom left in the status bar of the CLV-Setup user interface via the terminal interface (

•

While it is in operation, the CLV constantly monitors the laser diode and speed of the polygon mirror wheel. In addition, a watchdog circuit reacts to incorrect device states.

•

A timer automatically de-activates the laser diode in reading mode at the "Sensor input" and "Serial interface" trigger mode 10 minutes (default setting) after the beginning of a lasting reading pulse. However, it does not end the reading interval. The CLV outputs the following message via the terminal interface: " reading pulse is to be terminated by resetting the trigger signal. The next reading pulse re-activates the laser diode.

The CLV has diagnosed a system error. The "Device Ready" LED does not light up or extinguishes. The CLV tries a new system start.

The CLV has diagnosed an irregularity in the EEPROM and downloads the entire default setting to the RAM instead of the last permanently stored parameter record.

The CLV cannot download the parameter record stored in the EEPROM to the RAM.

The CLV cannot write the current parameter record from the RAM to the EEPROM.

The CLV has diagnosed an irregularity in the internal reference table for the focus positions selected by the user. It therefore downloads the default setting of the distance configurations.

8.5.6 Malfunctions: Configuration errors (parameterization)

Fault Possible cause Remedy

1. Auto Setup: The CLV does not read the presented, applicationspecific bar code (no confirmation from beeper)

2. Profile programming: CLV does not read the presented Profile bar code (no confirmation by the beeper)

•

CLV not in "Auto Setup" mode

•

If Auto Setup is started with Profile bar code No. 10: Wait time of 5 s after powerup has been exceeded

•

Bar code presented at incorrect reading distance

•

Bar code is in total reflection zone

•

Bar code quality not adequate

•

Wait time of 5 s after powerup has been exceeded

•

Wait time of 10 s after the first Profile bar code was presented has been exceeded

•

In Reading mode: CLV not pulsed

•

Check: Does the "Device Ready" LED light up? If so, the CLV is in "Reading" mode again. CLV-Setup user interface: Call up the Auto Setup function again via the V pull-down menu

•

Switch the CLV off and on again. Present the Profile bar code No. 10 within 5 s. Then the applicationspecific bar code.

•

Check whether the reading distance of the bar code lies within the specified reading range?

•

Optimize bar code alignment (scan line should strike the bar code at a skew of approx. 15 )

•

efer to Fault 1, Table 8-5,

Page 8-9

•

Switch the CLV off and on again. Present Profile bar code within 5 s.

•

Once the f irst Prof ile b ar co de has been read successfully, present the next bar code within 10 s, etc.

•

Pulse the CLV accordingly and present the first Profile bar code. Present the next bar code within 10 s, etc.
