Installation procedure (overview)

Reading pulses via switching input "Sensor 1" (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/S 60 Connection Module.

4. Connect the CLX to the AMV/S 60 Connection Module using the two cables no. 2 020 302. Alternatively, connect the device to the AMV/S 60 via the external parameter memory no. 2 020 307.

5. Connect the reading pulse sensor to the "Sensor" switching input in the AMV/S 60.

6. Connect the host to the host interface in the AMV/S 60. Adapt the AMV/S 60 to the host interface type of the CLX.

7. Switch on the power supply to the AMV/S 60. The "Device Ready" LED lights up after the CLX has started.

CLX with external parameter memory connected:

The "Device Ready" LED and the "Read Result" LEDs blink after the CLX has started. The CLX is

not

ready to start reading. See

8. Switch on your PC and start Windows

9. Install the "CLV-Setup" software, online CLV-Setup Help and, if necessary, the I-View-

Pro

HTML browser on your PC.

10. Connect the PC to the terminal interface of the CLX. To do so, connect the RS 232 cable (e. g. no. 2 014 054) to the "Service plug" in the AMV/S 60.

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.

CLX with external parameter memory connected:

First download the CLX parameter set to the external memory. Disconnect the AMV/S 60 briefly from the power supply to restart the CLX.

12. Carry out a test read using test bar codes (clock 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.

not

switch off the power to the AMV/S 60 (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

CLX with external parameter memory connected:

Copy the modified parameter set to the external parameter memory.

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

Safety information

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 terminal interface. The reading interval must be terminated by resetting the trigger signal. The laser diode is activated again by the next reading trigger.

The laser timeout can be set in the range of 1 min to 25 h or deactivated

Page 6-11

In the Percentage Evaluation mode and in the Free-running Reading mode the laser diode is constantly activated.

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

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" switchi ng in put instructs the CLX to sta rt th e reading process. The five "IN 0 ... 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 ... 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 terminal interface) using the CLV-Setup software or via the host interface/terminal interface using command strings.

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

Product description

3.2.1 Autofocus function

The autofocus function enables the CLX to detect the distance of an object during the reading process, without the need for external sensors, and then adjust the focus position automatically to the reading plane of the bar code. In order to do so, the CLX measures the object distance each time 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 programmed (teach-in) in the CLX without any objects present. During the reading process, the CLX then focuses on the object which it recognizes by comparing it to the distance profile of the background. Application: with unobstructed view of the object restricted by other objects that protrude into the reading plane. 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 (

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

123 5 8

Fig. 3-4: Dynamic focus control: classification of the reading range in distance configurations

6 7

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 ... IN 4" switching inputs, a command on the host interface/terminal 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 distance measurement of the autofocus function can additionally be used to define the distance configurations.

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.

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 extremely 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/S 60 Connection Module

The AMV/S 60 Connection Module should not be located further than 10 m from the CLX, since the "CLV-Setup" program on the PC accesses the terminal interface (RS 232) of the CLX via this module.

4.2.8 Count direction of the code position CP

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

Fig. 4-6

shows the count direction of the code position. The count direction of the code po-

sition is marked by a cross in the reading window.

By determining this data, the device can separate identical bar codes (code type, code length, and data content identical) and assign the bar code data in the reading result to its position on the object.

4.3 Mounting and adjusting the device

4.3.1 Mounting the CLX

1. Prepare the base for mounting the bracket as described in

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 All of the possible reading angles must be taken into consideration (see

Page 4-4

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

Fig. 4-6, Page 4-5

5. Mount the CLX bracket on the base.

Risk of damage to the housing!

The maximum depth of engagement of the two blind hole threads M 6 is 7 mm. Longer screws will damage the housing.

Use screws with the correct length.

6. Screw the screws M 6 through the bracket into the blind hole threads of the CLX.

7. Tighten the screws slightly.

8. Adjust the CLX as described below.

Chapter 4.2.2 Required

Fig. 4-5,

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 terminal interface.

The behavior of the "Read Result" LED also indicates the reading quality. The LED does not light up if the CLX cannot read the bar code (reading quality < 30 %). If the CLX is having problems reading the bar code (reading quality 30 % ... 90 %), the LED blinks. The CLX is aligned optimally when the LED lights up constantly (reading quality > 90 %). The scanning frequency in the default setting is 800 Hz.

1. Connect the CLX to the AMV/S 60 Connection Module and switch on the power supply

Chapter 5.5.3 Connecting the supply voltage, Page 5-13

(see After it has started, the CLX confirms that the self-test was successfuly and switches to reading mode ("Device Ready" LED lights up).

2. Connect the PC to the terminal interface of CLX via the RS 232 line using the internal 9-pin "Service" plug of the AMV/S 60 (see

Fine adjustment:

11. 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°.

12. 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

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

14. 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.

15. Adjust the CLX in such a way that the good read rate is between 70 ... 100 %. With event-controlled dynamic focus control, for each defined reading range (distance configuration), check the selected focus position and correct the parameter settings if necessary (see

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 ... IN 4" switching inputs are selected for dynamic focus control.

Risk of damage to the interface module!

Electrical components in the CLX may be damaged if the host interface is connected incorrectly. This also applies when the host interface connections are changed in the Connection Modules (configuration).

Connect the host interface as shown in

Check the connections carefully before you switch on the CLX.

1. Connect the host interface on the CLX to the host using shielded cables (EMC requirements). Ensure that the maximum cable lengths are not exceeded (see

Page 5-8).

Recommendation 2. Apply the shield on one side.

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 scan line appears as a cross.

5. Present the bar code pattern (

Table 6-2, Page 6-4

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

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)

Chapter 10.7 Configuring a CLX with command strings, Page 10-23

See

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

6.4.1 Configuring the CLX via the user interface of CLV-Setup

To be able to use CLV-Setup, a PC has to be connected and the program installed on it. The procedure for connecting the PC to the CLX is described in

Transferring a parameter set between CLV-Setup and the CLX

When the CLX is being paramete rized, CL V-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 CLX) 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) from the CLX’s memory (RAM). 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 CLX). With the help of the context menu (right mouse button), only the parameter just edited will be temporarily loaded (download parameter) into the CLX’s memory (RAM).

Loading a complete CLX parameter set (upload)

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

Function of the terminal 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 terminal interface. The number of bar codes output can, therefore, be higher than the number of those that were sent via the host interface in the reading result. In the default setting, this mode is selected for the terminal interface.

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

Chapter 10.10.1 Auxiliary input, Page 10-27

describes this function and the associated pro-

cedure 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 terminal interface provides information on the test result. The CLX does not output a reading result during the test routine.

Maintenance

7.1 Cleaning the CLX during operation

To ensure optimum reading performance, the reading window of the CLX must be clean at all times. For this reason, we recommend that you check the reading window at regular intervals, particularly if the device is operated under extreme conditions (dust, abrasion, humidity, finger prints).

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

damage your eyesight.

Never look directly into the path of the beam (similar to sunlight).

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

Switch off the device while it is being cleaned.

Damage on the reading window!

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

Use a mild, non-scouring detergent.

Never use scratching or scouring motions to clean the reading window.

Cleaning the reading window:

Clean the reading window at regular intervals with a mild, non-scouring detergent, e. g. an antistatic glass cleaning fluid. lint-free cloth.

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

Fig. 7-1

shows the area that require cleaning. Use soft,

7.2 Maintenance

The CLX does not require any maintenance. Its self-monitoring functions ensure fault-free operation over long periods of time. Any faults or malfunctions are displayed on the terminal interface. The messages can be displayed on the screen in the extended mode of the Terminal Emulator in the CLV-Setup program. See

Chapter 8.2 Monitoring error and malfunctions, Page 8-1

7.3 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. Remove the glass panel from the reading window and send it to be recycled.

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

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

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

•

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

•

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 enabled by default. The CLX displays the diagnosed error as a numeric combination on the terminal interface (see

•

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 distance measurement 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: The reading interval must be terminated by resetting the trigger signal. The laser diode is activated again by the next reading trigger.

The CLX has diagnosed a system error. The "Device Ready" LED does not light up or extinguishes. The system is restarted.

The CLX has diagnosed an irregularity in the EEPROM and downloads the entire default settings to the RAM instead of the permanently stored application-specific parameters.

The CLX cannot load the application-specific parameters, permanently stored in the EEPROM, into the RAM.

The CLX cannot write the current parameters in the RAM to the EEPROM.

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

After switching on the power supply:

•

The CLX has no power

•

The CLX has diagnosed a device error during the selftest

•

Check wiring (power connector fitted securely to the AMV/S 60 Connection Module). Measure voltage at pin 1 and pin 5.

•

Switch CLX off and on again. Does the LED light up? If not, contact SICK Service department

During operation:

•

The CLX is not in "Reading" mode

•

The CLX has deactivated the laser diode 10 min. (default setting) after the start of the current reading pulse (Trigger mode: sensor input/serial interface)
