Operating Instructions

Installation procedure (overview)

Reading pulses via switching input "Sensor" (default setting)

1. Check the delivery to make sure that none of the components is missing.

2. Mount the CLX at the reading station and align it with the object carrying the bar code.

3. Mount the AMV/S60 Connection Module.

4. Connect the CLX to the AMV/S60 Connection Module using the two cables no. 2020302. Alternatively, connect the device to the AMV/S60 via the external parameter memory no. 2020307.

5. Connect the reading pulse sensor to the "Sensor" switching input in the AMV/S60.

6. Connect the host to the host interface in the AMV/S60. Adapt the AMV/S60 to the host interface type of the CLX.

7. Switch on the power supply to the AMV/S60. The "Device Ready" LED lights up after the CLX has started.

CLX with external parameter memory (in connector cover) connected:

After the CLX has started, it copies the internal parameter set to the external parameter memory if the memory is empty. Then the "Read Result" LED lights up.

8. Switch on your PC and start Windows

9. Install the "CLV-Setup" software and online CLV-Setup Help from the CD-ROM ("Manuals & Software") on your PC.

10. Connect the PC to the auxiliary interface of the CLX. To do so, connect the 3-core RS 232 data cable (null modem cable) (e. g. no. 2014054) to the "Service plug" in the AMV/S60.

11. Start the "CLV-Setup" program. CLV-Setup establishes communication with the CLX and uploads the parameter set. The parameters are then displayed on the tabs.

12. Carry out a test read using test bar codes (trigger the CLX accordingly). Display the reading result in the Terminal Emulator window of the "CLV-Setup" program.

13. Configure the CLX for the application using the settings on the tabs in CLV-Setup. Copy (download) the modified parameter set to the CLX temporarily. Do not switch off the power to the AMV/S60 (CLX)!

14. Test the application under realistic conditions.

15. Check whether the data is transmitted correctly between the CLX and host.

16. If necessary, correct and optimize the parameter values. Copy (download) the parameter set permanently to the CLX.

CLX with external parameter memory (in connector cover) connected:

Copy the modified parameter set to the external parameter memory when CLV-Setup asks you for confirmation.

17. Save the parameter set as a configuration file "*.scl" in the "CLV-Setup" program.

(minimum requirement: Windows 95TM).

The CLX can then be operated with the application-specific settings.

CLX490 Compact OMNI Scanner

2.3 General 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 AMS60 Connection Module (accessory) for the CLX is connected to a mains voltage of 230 V AC 50 Hz or 115 V AC 50 to 60 Hz.

¾ When working with electrical equipment, always follow the relevant safety specifications.

Laser beam can cause blindness! The CLX 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 the eyes of other persons.

¾ Mount and align the CLX490 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).

Note No maintenance required to keep this product in compliance with laser class II.

Laser warnings

The laser warning symbols (Fig. 2-1) can be found on the CLX at the following locations:

The laser warning symbol is positioned on the reading window. The GB/US laser warning is located on the side containing the electrical connections (see Fig. 3-1, Page 3-3.)

Fig. 2-1: Laser warning labels on the CLX

Note A set of laser warnings in German/US English and French/US English is included in the de-

livery scope. The GB English/US English warnings can be pasted over with these if necessary.

If the CLX is installed in a machine/panel with the result that the laser warning labels are no longer visible, additional warnings in the same language (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 CLX is equipped with monitoring circuits that deactivate the laser diode in the event of a malfunction.

Activation and deactivation of the laser diode is controlled by the reading pulse trigger.

A 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 CLX outputs the message

"Laser safety timeout"

on the auxiliary 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 6-7,

Page 6-11).

In the "Percentage Evaluation" mode as well as in the pulse mode "Free-running", in reading mode, the laser diode is constantly activated. In the pulse mode "Object Polling" the laser diode is activated due to the parameterized search/pause ratio.

Note In Reading mode, the CLX carries out a measurement referencing at regular intervals. During

referencing, it turns the laser diode on for a maximum of 10 seconds.

3.2 Method of operation

The CLX first scans the bar code with a folded scan line (resulting in a cross) and then decodes it. The data is forwarded via the main data interface (serial host interface) to a host/ PC for further processing. An overview of the CLX functions is provided in Fig. 3-2.

The CLX 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 CLX derives useful diagnosis data from the reading process and can transfer it also to the host. It also records operating data that can be interrogated at any time. The quality of the read can be checked in percentage evaluation mode.

To start the reading process when an object is located in the reading field, the CLX requires a suitable trigger. This opens an internal time window ("reading interval") in the CLX. In the default configuration, this trigger is supplied by an external reading pulse sensor. Alternative trigger sources include free-running mode or a command via the host interface (for more complex applications: OTC trigger).

With small object distances (object distance < reading gate length) the bar code has to be allocated to the right object with the help of the internal tracking of the CLX.

The current operating status is indicated by four LEDs.

If the trigger is supplied externally, the "Sensor" switching input instructs the CLX 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 4” input can also be assigned to special functions. The four "Result 1 to Result 4" switching outputs can be assigned to different functions alternativly for displaying the result status and also control external devices, such as a PLC.

The CLX is operated and configured via the auxiliary interface (serial auxiliary interface) using the CLV-Setup software or via the host interface/auxiliary interface using command strings.

System, warning, and error messages help you configure the device and locate the source of errors during startup and reading mode.

Operating Instructions Chapter 3

CLX490

Product description

3.2.1 Autofocus function

The autofocus function enables the CLX to detect the distance of an object without the need for external sensors, and then adjust the focus position automatically. In order to do so, the CLX measures the object distance in its reading field in front of the reading window and internally creates a distance profile. Following this, it positions the focus on the object.

3 operating modes are provided for various applications:

• Minimum distance: the CLX focuses on the minimum distance in the distance profile

and ignores the background in the reading field. Application: with unobstructed view of the object without any surrounding objects protruding into the reading plane. One object with bar code(s) only is inside the reading field during one reading pulse.

• Differential background: the distance profile of the reading field background is pro-

grammed (teach-in) in the CLX without any objects present. The CLX focuses on the object which it recognizes by comparing the object with the background. Application: with unobstructed view of the object restricted by other objects that protrude into the reading plane. One object with barcode(s) only is inside the reading field during one reading pulse.

• Differential background and tracking: if several objects with different distances are

positioned in the reading field at the same time (distance conflict), the CLX focuses on the object that is nearest to but has not exceed its internal focus switchover point. Application: in OTS operation (applications with tracking by the OMNI Tracking Controller OTC 400), or stand alone in internal tracking mode.

The distance profile of the background can also be displayed in the "CLV-Setup" program. The reading field is defined by the autofocus range. The park setting of the focus position, from which the device focuses for each read, can be specified in addition to a time and/or position-related delay (timeout or hysteresis). If necessary, an offset can be defined for the focus position to be set by the measurement. The depth of field, which radiates in the direction of the scan line and is caused by the V-principle of the beam deflection, is optimized as a result (Fig. 3-3).

3.2.2 Event-controlled dynamic focus control

As an alternative to the autofocus function, the CLX 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. 3-4).

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 is a signal combination at the "IN 0 to IN 4" switching inputs, a command on the host interface/auxiliary interface or the integrated timer (e. g. for search mode). The distance configurations are assigned to the swichover sequence by means of a programmable assignment table. The object distance measurement of the autofocus function can additionally be used to define the distance configurations.

3.2.3 Additional components

Heater

The CLX can be permanently equipped with a heater for applications involving temperatures up to max. –30 °C (e. g. in a freezer).

The external parameter memory is located in a connector cover which, when mounted, covers the two electrical terminals on the CLX (IP 65). The parameter memory saves you time when a CLX 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 10-8.

3.3 Indicators and control elements

3.3.1 Control elements

The CLX is operated and configured via the auxiliary interface using the CLV-Setup program or using command strings sent via the host interface/auxiliary interface. A variety of parameter options allow you to adapt the device to a wide range of applications.

The following can be defined:

• The configuration of the code types

• The read, evaluation, and output properties

• The communication parameters of the host interface

• The structure of the data output string for Good Read and No Read on the host interface

• The function of the auxiliary interface

Chapter 10.6 Installing and operating the "CLV-Setup" program, Page 10-15 describes the

procedure for installing the "CLV-Setup" program and explains how to use it. The parametrization (configuration) procedure is explained in Chapter 6.4 Configuring (parameterization)

the CLX, Page 6-4.

3.3.2 Function of the LEDs

Four LEDs indicate the operating status, activity of the laser diode, reading result status, and data transfer on the host interface. The LEDs are located on the rear of the device (Fig. 3-5).

If the optional external parameter memory is connected, the LEDs also indicate whether the memory was successfully accessed.

Supplied laser warnings:

Fig. 4-1: Replacing the laser warning labels

4.2.5 Selecting the mounting location

When you select the mounting location, the distance between the CLX and the host and between the CLX and the bar code are important.

Distance between the CLX and the host

The CLX can be mounted at a maximum distance of 1,200 m from the host without a connection to the SICK network or a bus. In practice, however, the distance depends on the physical configuration of the host interface and the data transfer rate (see Table 5-7,

Page 5-8).

Distance between the CLX and the AMV/S60 Connection Module

The AMV/S60 Connection Module should not be located further than 10 m from the CLX, since the "CLV-Setup" program on the PC accesses the auxiliary interface (RS 232) of the CLX via this module.

4.2.7 Distance between the CLX and the object

Basic alignment between the CLX and bar code

The CLX is used for reading omnidirectionally oriented bar codes on the lateral or upper sides of objects. Fig. 4-4 shows the basic alignment of the CLX.

Reading distance to the object

The distance between the reading window of the CLX and the object must not exceed the technical limits. The height of the reading field is shown as a function of the reading distance for various resolutions (module widths) in Chapter 10.2.2 Reading performance data

CLX490 Compact OMNI Scanner, Page 10-2.

Fig. 4-4 shows the definition of the reading distance "a" (radial measured) from the reading

window.

Reading distance a

Fig. 4-4: Definition of the reading distance a to bar code and convoyer direction

Due to the X-principle of beam deflection, the reading field height (for evaluating the useful length of the scan line) depends on the readling distance.

Angular alignment of the CLX

All possible reading angles that can occur between the scan line and the bar code must be taken into consideration (Fig. 4-5 and Table 4-1).

Installation

Note If reading from the front, mount the CLX 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°.

4.2.8 Count direction of the reading angle RA

Explanation The CLX 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 reading angle (RA value) of the center of the bar code within the scan.

Fig. 4-6 shows the count direction of the reading angle. The count direction of the reading

angle is marked by a cross in the reading window.

By determining this data, the device can separate identical bar codes.

Tip

100 0

4.3 Mounting and adjusting the device

4.3.1 Mounting the CLX

1. Prepare the base for mounting the bracket as described in Chapter 4.2.2 Required

accessories, Page 4-1.

2. Place the object containing the bar code within the reading field of the CLX (in the position at which it is to be read) with the conveyor belt switched off.

3. Allign the CLX reading window in parallel to bar code surface. Consider the positioning of the CLX in relation to the conveyor direction (see Fig. 4-4, Page 4-4). All of the possible reading angles must be taken into consideration (see Fig. 4-5,

Page 4-4).

4. If it is relevant for the evaluation, note the count direction of the reading angle (see

Fig. 4-6, Page 4-5).

5. Mount the CLX bracket on the base.

Risk of damage to the device!

The maximum depth of engagement of the two blind hole threads M6 is 7 mm. 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 CLX.

7. Tighten the screws slightly.

8. Adjust the CLX as described below.

4.3.2 Adjusting the CLX

The CLX can be adjusted in Percentage Evaluation mode. In this mode, the CLX displays the quality of the bar code reads that enter the CLX reading field statically (the object is not moved on the conveyor belt). In the Free-running mode the CLX performs 100 scans and evaluates the reading quality statistically. It then outputs the reading results every 2 s on the auxiliary interface.

Note In default setting, the CLX operates in the autofocus mode "Minimum distance“. As a result,

the CLX focuses on the object that is nearest in Percentage Evaluation mode. The view on the object with the scan line must be unobstructed, i. e. any other objects must not protude into the autofocus space. If they do so, the autofocus mode "Differential background“ must be selected. Alternatively a fixed focus position can be set.

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 CLX to the AMV/S60 Connection Module and switch on the power supply (see Chapter 5.5.3 Connecting the supply voltage, Page 5-13). After it has started, the CLX confirms that the self-test was successfuly and switches to reading mode ("Device Ready" LED lights up).

7. From the V

IEW menu, choose PERCENTAGE EVALUATION.

The dialog box for entering the distance configuration appears.

8. Click the relevant distance configuration for the reading distance:

– with autofocus mode the distance configuration no. 1

– with event-controlled dynamic focus control the distance configuration that matches

the reading distance of the object (default: no. 1, focus position F = 1,200 mm).

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 6-17).

Monitor the reading quality (%) during each of the subsequent steps!

Fine adjustment:

10. Align the CLX in such a way that the angle between the scan line and the bars on the bar code CLX is almost 90°.

11. To avoid interfering reflections, align the CLX reading window in parallel to the bar code surface. Consider the positioning of the CLX in relation to the convoyer direction (see

Fig. 4-4, Page 4-4).

12. If necessary, align the intersecting point of folded scanline exactly with the bar code.

13. Move objects carrying bar codes into the CLX 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 CLX 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 6-8).

15. Tighten the screws on the CLX.

The CLX is aligned with the bar code.

4.4 Mounting the external components

4.4.1 Mounting the AMV/S60 Connection Module

1. Mount the AMV/S60 Connection Module near the CLX. The distance between the AMV/S60 and CLX should not exceed max. 10 m.

2. Mount the AMV/S60 in such a way that accessed to the open device is always possible. The auxiliary interface of the CLX is accessed via the internal "Service" plug.

Detailed information on the mounting and electrical installation procedures is provided in the Operating Instructions for the "AMV/S60 Connection Module" (order no. 8008296).

4.4.2 Mounting the external reading pulse sensor

If the CLX is triggered by an external reading pulse sensor, the sensor must be mounted in the vicinity of the CLX. 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.

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. The exact position fo the external sensor in relation to the scanner can be seen in Fig. 10-3 to

Fig. 10-5 onwards page 10-4.

Note In default setting, the CLX operates in the autofocus mode "Minimum distance“. As a result,

the CLX focuses on the object that is nearest. The view on the object with the scan line must be unobstructed, i. e. any other objects must not protude into the autofocus space. If they do so, the autofocus mode "Differential background“ must be selected. Alternatively a fixed focus position can be set.

1. Mount the reading pulse sensor.

2. Connect the reading pulse sensor to the "Sensor" switching input of the CLX via the AMV/S60 Connection Module (see Chapter 5.5.7 Connecting the switching inputs,

Page 5-16).

3. Connect the CLX to the AMV/S60 Connection Module and switch on the power supply to the module (see Chapter 5.5.3 Connecting the supply voltage, Page 5-13). After it has started, the CLX confirms that the self-test was successfull and switches to Reading mode ("Device Ready" LED lights up).

4. Connect the PC to the auxiliary interface of CLX. To do so, connect a 3-core RS 232 data cable (null modem cable) to the internal 9-pin "Service" plug of the AMV/S60 (see

The CLX operates with the "Sensor" switching input as an external trigger source. The reading pulse starts when the input is energized (high).

4.4.3 Mounting the sensors for detecting the object distance

If the dynamic focus control function of the CLX is triggered by external sensors, suitable sensors must be mounted in the vicinity of the CLX. Fig. 4-7 shows an example of a read operation from above. The sensors must be arranged in such a way that all of the potential object heights are classified uniquely and overlapping reading ranges occur that can be formed with the depths of field of the CLX. 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.

5.4 Preparations for electrical installation

5.4.1 Requirements for the host interface

The host interface of the CLX can be operated as an RS 422/485 or an RS 232 interface.

Table 5-7 shows the recommended maximum cable lengths as a function of the selected

data transfer rate.

Interface type Transfer rate Distance from host

RS 232 up to 19,200 bd

38,400 to57,600 bd

RS 422/485

1) with suitable line termination according to specifications

Table 5-7: Maximum cable lengths between the CLX and host

max. 38,400 bd max. 57,600 bd

¾ To prevent interference, do not lay the cables parallel with power supply and motor ca-

bles over long distances, e. g. in cable ducts.

5.4.2 Supply voltage

max. 10 m max. 3 m

max. 1,200 m max. 500 m

The CLX requires a supply voltage of 18 to 30 V DC for operation without a heater and 24 V DC +20 %/–10 % for operation with a heater (functional extra-low voltage in accordance with IEC 364-4-41). The functional extra-low voltage can be generated by using a safety transformer pursuant to IEC 742.

The power consumption of the individual types is as follows:

Type Voltage Heater

"IN 0 to IN 4" switching inputs

If the Autofocus function is not used and the CLXs dynamic focus control function is to be triggered by external sensors, the sensors are connected to the five "IN 0 to IN 4" inputs. 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 4:

The "IN 4" input can alternatively be used as an input for a belt increment signal or for the reading pulse end. 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 CLX and the terminal assignment in the AMV/S 60. Table 5-19,

5.5.8 Connecting the "Result 1 to Result 2" switching outputs

The four switching outputs can be assigned different functions for outputting result statuses independently of each other. If the assigned event occurs during the reading procedure, the corresponding switching output becomes live at the end of the reading pulse for the selected pulse duration. The pulse duration can be set individually for each output.

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

Fig. 5-6 shows the connections for the "Result 1 to Result 4" switching outputs. Table 5-22 shows the pin assignment on the CLX and the terminal assignment in the

6.3 Quick start

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

6.3.1 Switching the CLX on for the first time with the factory default settings

1. Connect the CLX to the AMV/S60 Connection Module using the two cables no. 2020302.

2. Connect the reading pulse sensor (e. g. photoelectric reflex switch, switch) to the "Sensor" switching input of the CLX via the AMV/S60 (see Chapter 5.5.7 Connecting the

switching inputs, Page 5-16).

3. Switch on the power supply of the AMV/S60. The CLX starts. The "Device Ready" LED lights up. The "Result 1" ("Device Ready") output switches.

CLX with external parameter memory connected (default: Start with ext. parameters): If an external parameter memory in the connector cover containing a corresponding parameter set is connected to the CLX, the "Device Ready" LED blinks for 10 s when the device starts up correctly and then lights up constantly. If the external parameter memory in the connector cover is empty, the CLX copies its parameter set to the external parameter memory. Then the "Device Ready" LED lights up. The CLX is ready for operation.

4. Start the reading pulse: block the light path of the photoelectric switch or close the switch. The "Laser On" LED lights up. The CLX switches the laser diode on and the red scan line appears as a cross.

5. Present the bar code pattern (Fig. 6-1) to the CLX at the reading distance specified in

Table 6-2, Page 6-4.

The scan line must not hit any object in a distance closer to the CLX than the represented bar code (default setting: autofocus mode "Minimum distance").

6. Align the bar code in such a way that the red scan line is almost at a 90° angle to the bars.

7. End the reading pulse: unblock the light path of the photoelectric switch or open the switch. The "Laser On" LED is extinguished. The CLX switches the laser diode off. The CLX confirms that the bar code was read successfully (the "Result" LED lights up for 100 ms). The "Result 2" ("Good Read") output is switched for a duration of 100 ms.

The CLX can now be operated with the factory default settings. The device can be switched off without the configuration data being lost as no changes have been made to the parameter set.

6.4 Configuring (parameterization) the CLX

The CLX 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 CLX parameter set that has already been created.

The CLX 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 CLX with command strings, Page 10-25.

In the Parameterization mode, the CLX outputs no reading result.

6.4.1 Configuring the CLX with 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 CLX is described in Chapter 5.5.6 Connecting the

PC, Page 5-15. The procedures for installing and starting the "CLV-Setup" program and for

starting and operating the user interface are described in the Appendix (Chapter 10.6 In-

stalling and operating the "CLV-Setup" program, Page 10-15).

Transferring a parameter set between CLV-Setup and the CLX

Upload

When the CLX is being parameterized, CLV-Setup runs in the offline mode. To be able to modify the current parameter set of the CLX, this first has to be loaded to CLV-Setup from the CLX. This procedure is referred to as an upload ("Upload from CLV" in the CLX490 menu or [F3] key) during which CLV-Setup always loads a complete copy of the current CLX 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 CLX’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 CLX. CLV-Setup always sends a copy of the complete parameter set to the CLX, i. e. all of the existing parameter values in the CLX are overwritten. The procedure for transferring and saving the parameter values in the CLX is referred to as a download ("Download to CLV" in the CLX490 menu or [F4] key).

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 CLX’s memory (RAM). To finish the parametrization done by this way all parameters must be download again to the CLX with the "Permanent" option.

Operating Instructions Chapter 6

Operation

Loading a complete CLX parameter set (upload)

¾ Click in the toolbar or press [F3] key.

CLV-Setup loads the current CLX parameter set from the RAM of the CLX 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 follo-

wing the conventions for command strings. When the parameter set is then saved, these parameters are also saved.

Transfering and saving a complete CLX 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 CLX.

ERMANENT: CLV-Setup copies the parameter set to the RAM and to the EEPROM of the

CLX.

EMPORARY: CLV-Setup copies the parameter set to the RAM only. The changes are lost

when the CLX 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 CLX either permanently or temporarily.

CLX 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

TART WITH EXTERNAL PARAMETERS.

¾ Choose the C

OPY NOW INTERNAL PARAMETER SET TO EXTERNAL MEMORY option.

CLV-Setup then instructs the CLX 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 CLX, Page 10-10.

6.5 Operating modes and outputing the reading result

The following CLX operating modes/functions can be selected in CLV-Setup:

Standard operating mode:

• Reading mode

For setup:

• Percentage evaluation

For adapting the device to the application at hand:

• Configuring (parameterizing ) the CLX

See Chapter 6.4.1 Configuring the CLX with CLV-Setup, Page 6-4

• Background teach-in

• Background analysis

For monitoring purposes/troubleshooting:

• Display and edit operating data

• Reading diagnosis

• Monitor host interface

• Auxiliary input

• Self-test

6.5.1 Reading mode (standard operating mode)

The CLX performs a self-test after it has been switched on. It switches to Reading mode ("Device Ready" LED lights up). In the default setting the "Sensor" switching input is the (external) trigger source of the reading pulse. The reading result is output by the CLX at the end of the reading pulse via the host interface (default setting) and auxiliary 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 auxiliary interface can be displayed in the CLV-Setup Terminal Emulator. The CLX auxiliary 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 auxiliary interface has a fixed, invariable format.

The Reading mode can be called up by choosing V

IEW in the menu bar or via the Terminal

Emulator.

Displaying the reading result in the Terminal Emulator:

1. Click in the toolbar. The Terminal Emulator window is then displayed.

2. In the D

EVICE MODE section, choose READING MODE.

3. Present the bar code pattern from Fig. 6-1 to the CLX and activate the reading pulse.

The scan line must not hit any object in a distance closer to the CLX than the represented bar code (default setting: autofocus mode "Minimum distance").

The "Sensor" LED lights up and the red scan line appears. Also refer to Chapter 6.3.1

Switching the CLX on for the first time with the factory default settings, Page 6-3.

Operating Instructions Chapter 6

CLX490

Operation

4. Ending the reading pulse. The CLX displays the reading result in the output window of the terminal emulator. The "Read Result" LED lights up for a duration of 100 ms (default setting).

Fig. 6-2, Page 6-15 shows two examples of the output of a reading result: Good Read and

No Read. The reading result comprises the data contents of the bar code(s) and the reading diagnosis data. Fig. 6-3, Page 6-16 explains the structure and function of the reading diagnosis data for Good Read, and Fig. 6-4, Page 6-16 for No Read.

Note The CLX only outputs several bar codes in the reading result of the host interface if the

parameterized minimum and maximum number of bar codes is > 1, and several bar codes have been presented to it. The number of bar codes to be read/output for each reading interval can be selected in the C

ODE CONFIGURATION tab in the NUMBER OF CODES section.

The reading result of the host interface can also be displayed. Chapter 6.5.6 Monitor Host

Interface, Page 6-22 describes the procedure for this and the structure of the reading result

in the default setting.

CLV-Setup sends a stop command to the CLX. The "Sensor" LED is extinguished. The CLX switches off the laser diode. The CLX displays the reading result in the output window of the Terminal Emulator. The "Read Result" LED lights up for a duration of 100 ms (default setting).

6.5.2 Percentage evaluation

In the Percentage evaluation mode, the quality of the reading function is assessed (no conveyor movement).

The CLX performs 100 scans in the free running mode and evaluates the reading quality. It outputs the reading result continuously every 2 s via the auxiliary 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 V device function via CLX490 (interactively), or via the Terminal Emulator.

Note Autofocus mode:

If the CLX operates with autofocus in stand-alone configuration, the Percentage evaluation mode can only be started in the Autofocus mode "Minimum distance" or "Differential background". The CLX fixes the timeout of the automatic focus position switchover to 30 ms, the preferred focus position is set to the last recognised object. If the CLX operates with autofocus in OTS mode ("Differential background and tracking"), the CLX switches automatically to the autofocus mode "Differential background“ during the the Percentage evaluation mode.

The standard decoder has to be set temporarily for the percentage evaluation.

6.5.5 Reading diagnosis

Function of the auxiliary interface. In this mode, the CLX outputs the data contents of all the bar codes that were read – including those that, according to the evaluation criteria, were not read properly and were thus incorrect – together with the associated reading diagnosis data via the auxiliary interface. The number of bar codes output can, therefore, be higher than the number of those that were sent via the host interface in the reading result. In the default setting, this mode is selected for the auxiliary interface.

Fig. 6-3, Page 6-16 shows the output format of the auxiliary interface.

In the default setting, the CLX doesn’t output any reading diagnosis data via the host interface.

Function of the auxiliary interface. In this mode, the CLX accepts a bar code entered at the auxiliary interface (via the keyboard or handheld scanner with decoder). It sends the bar code to the host in a separate data string via its host interface. No reads can, therefore, be corrected by transmitting missing bar codes subsequently.

Chapter 10.10.1 Auxiliary input via auxiliary interface, Page 10-29 describes this function

and the associated procedure in greater detail.

6.5.8 Self-test

After the CLX has been switched on, it performs a self-test before it is initialized with the parameter set. The test can be called up explicitly at any time via CLV-Setup. During the selftest, the CLX checks that its hardware components are functioning correctly. A final message via the auxiliary interface provides information on the test result. The CLX does not output a reading result during the test routine.

6.6 CLX messages

The CLX outputs encoded system and error messages via the auxiliary interface to report user actions or events in the reading process. When the system is started, the CLX also outputs system messages in plain text (English). If configured accordingly, the CLX transfers the error status ST in the data output string of the host interface.

6.6.1 Displaying messages

In the 4th field from the left in the status bar at the bottom of the screen, CLV-Setup displays system and error messages that occur at the auxiliary interface of the CLX. These are recorded in a file, which is continuously updated. The messages have the following format:

• System message: "CLV SYS-Message: xxx"

• Error message: "CLV SYS-Failure: xxx"

The additional system messages in plain text can be displayed in the terminal emulator if CLV-Setup and the terminal emulator are started before the CLX is connected.

Additional messages:

When the system is started, these system messages inform the user whether the starting process was successful. No further measures are normally required.

Chapter 10.5 System messages, Page 10-14 explains the contents of the messages.

Error messages:

Error messages indicate the following types of error:

• a device defect

Chapter 8.3 Error messages, Page 8-2 lists the messages with the associated corrective

measures.

Note To call up the most recent error to occur in the CLX, enter command "2?SF" in the command

line of the terminal emulator.

6.7 Switching off the CLX

1. If the parameter set was modified in CLV-Setup or was only stored temporarily in CLX via a download ("Temproray" option or via context menu (right mouse button)), the parameter set must be stored permanently in the CLX by choosing the P storage option.

2. Save the parameter set as a configuration file "*.scl" in CLV-Setup.

3. Switch off the power supply of the AMV/S60 or unplug both of the CLX’s connecting cables from the connection module.

The last parameter set stored permanently in the CLX remains valid.

Maintenance

7 Maintenance

7.1 Maintenance during operation

The CLX functions maintenance free. Maintenance is not required to guarantee laser class 2 of the CLX.

Note Don’t open the device. The warranty will be forfeited if the device is opened.

The CLX indicates any faults or malfunctions by outputting coded system and error messages (e. g. "CLV SYS-Failure: 071") via its auxiliary interface. The messages are displayed in the "CLV-Setup" program window in the fourth field from the left on the bottom, in the status line (see also Chapter 8.3 Error messages, Page 8-2). CLV-Setup logs the messages in a file.

7.2 Cleaning the CLX

Recommendation In order to make use of the full optical reading capacity of the CLX, the reading window

should be checked regularly (e. g. weekly) for soiling. This is especially recommended when operating the device in harsh conditions (dust, abrasion, humidity, finger prints, etc.).

7.2.1 Cleaning the front window

Laser beam can cause blindness! The CLX uses a class 2 red-light laser. Looking directly at the laser beam can seriously

damage your eyesight.

¾ As with sunlight, never look directly into the laser beam.

¾ Switch off the device while it is being cleaned.

¾ Never look directly into the reading window while the device is in operation.

Damage on the reading window!

The reading window is made of glass. Scratches and streaks on the window will reduce the reading performance.

¾ Do not use aggressive cleaning agents.

¾ Do not use cleaning agents which cause increased abrasion (e. g. powder).

¾ Avoid cleaning motions at the reading window which could cause scratches or abrasion.

Cleaning the reading window

Note Electrostatic charges cause dust particles to stick to the reading window.

This effect can be combated by using anti-static SICK synthetic cleaner (no. 5600006) in combination with a SICK lens cloth (no. 4003353).

¾ Use a clean, soft brush to free the reading window (Fig. 7-1, Page 7-2) from dust.

¾ If necessary, additionally clean the reading window with a clean, damp, lint-free cloth

and a mild, anti-static window cleaning fluid.

Chapter 7 Operating Instructions

Maintenance

CLX490 Compact OMNI Scanner

Clean here

Fig. 7-1: Cleaning the reading window

If the reading window is scratched or damaged (cracked, broken), it must be replaced. Please contact the SICK Service.

Cleaning the housing

In order to ensure sufficient cooling for the CLX, make sure that the housing is always clean.

¾ Use a soft brush to free the housing from dust.

¾ If necessary, clean the LEDs on the rear of the device.

7.2.2 Cleaning other optical surfaces

If an external reading pulse generator and/or object-height detection sensors are used (e.g. photoelectric reflex switches), further sensors with optical effective surfaces can be installed. Soiling of these surfaces can cause incorrect switching behaviour.

¾ In order to prevent incorrect switching behaviour, remove soiling from the optical effec-

tive surfaces of the external sensors.

Clean here

Maintenance

7.3 Checking the incremental encoder

If an incremental encoder is used, check the correct position on the conveyor.

¾ Ensure that the incremental encoder always contact the conveyor so that the friction

wheel turns without slipping.

7.4 Disposal

Irreparable devices or devices that are no longer required must be disposed of in an environmentally-friendly manner:

1. Always observe the applicable national waste disposal regulations.

2. Remove the CLX housing.

3. Remove the electronic modules.

4. Send the chassis and cover (aluminium) to be recycled.

5. Send the electronic modules for disposal as problem waste.

At present, SICK AG does not accept any unusable or irreparable devices.

Troubleshooting

8 Troubleshooting

8.1 Overview of the possible errors and malfunctions

8.1.1 Mounting errors

• CLX aligned incorrectly with the object carrying the bar code (e. g. blanking)

• Reading pulse sensor positioned incorrectly

• With event-controlled focus control: sensors for object height detection positioned

incorrectly

8.1.2 Electrical installation errors

• Interfaces on the CLX connected incorrectly (wiring error in AMV/S60)

• Host interface on AMV/S60 configured incorrectly

8.1.3 Parameter errors

• 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 Malfunctions

• Start/stop mode: no external reading trigger, more than one object in the reading field

• Tracking mode: gap between the objects in conveying direction fallen below minimum

• Laser timeout for incorrectly terminated reading pulse

• Device error (hardware/software)

8.2 Monitoring error and malfunctions

The CLX is self-monitoring:

• After the power supply has been switched on, the CLX automatically carries out a selftest, in which it checks important hardware components, before it is initialized (parameter set loaded and device functions initialized). The self-test can be repeated at any time by cancelling Reading mode. See Chapter 6.5.8 Self-test, Page 6-24.

• If the CLX detects an error during the self-test or at any other time, it outputs the error status ST=3 on the host interface. Prerequisite: the error status is enabled for transmission. This is disabled by default. The CLX displays the diagnosed error as a numeric combination on the auxiliary interface (see Table 8-1, Page 8-2).

• While it is in operation, the CLX constantly monitors the laser diode and speed of the polygon mirror wheel. In addition, a watchdog circuit responds to error statuses. The CLX carries out referencing at regular cycles. To do so, the laser diode is switched on for max. 10 s.

• 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 CLX outputs the message: "Laser safety timeout" on the auxiliary interface. The reading interval must be terminated by resetting the trigger signal. The laser diode is activated again by the next reading trigger.
