Operating Instructions

CLV 490 Bar Code Scanner

Installation procedure (overview)

CLV in stand-alone configuration

Start/stop mode: Reading trigger via “Sensor“ switching input (default setting)

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

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

3. Mount the CDB 420 or CDM 490 Connection Module.

4. Connect the CLV as followed: CDB 420 Connection Module: using the cable no. 2 027 046. Alternatively, connect the CLV using the external parameter memory no. 2 030 023. CDM 490 Connection Module: using two cables no. 2 020 302. Alternatively, connect the CLV using the external parameter memory no. 2 020 307.

5. Mount the sensor for starting/stopping the reading pulse.

6. Connect the reading pulse sensor to the "Sensor (1)" switching input in the CDB 420 or CDM 490.

7. Connect the host to the host interface in the CDB 420 or CDM 490.

8. Switch on the power supply to the CDB 420 or CDM 490. The "Device Ready" LED lights up after the CLV has started.

CLV with external empty parameter memory connected (no. 2 020 307 or 2 030 023):

After the CLV has started, it copies the internal parameter set to the external parameter memory if no CMC 400 parameter memory is available in the CDB 420/CDM 490.

Line scanner with oscillating mirror:

In the default setting, the CLV deflects the scan line around the position CW = 50 with a frequency of 1 Hz and an oscillating amplitude of max. ±20° (±40 CW).

9. Switch on your PC and start Windows

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

11. Connect the PC to the terminal interface of the CLV. To do so, connect a 3-core RS 232 data cable (null modem cable), e. g. no. 2 014 054 to the "Aux" plug in the CDB 420 or CDM 490.

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

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

14. Configure the CLV for the application using the settings on the tabs in CLV-Setup. Copy (download) the modified parameter set to the CLV temporarily. Do not switch off the power to the CDB 420 or CDM 490 (CLV)!

15. Test the application under realistic conditions.

16. Check whether the data is transmitted correctly between the CLV and host.

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

CLV with external parameter memory connected:

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

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

(minimum requirement: Windows 95TM).

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

CLV 490 Bar Code 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.

Risk of injury by electrical current

In the CDM 490 Connection Module, the optional CMP 490 Power Supply Module is connected to a mains voltage of 100 to 250 V AC/ 50 to 60 Hz.

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

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

damage your eyesight.

The entire glass window acts as a laser outlet aperture.

Caution – use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

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

¾ Do not direct the laser beam at other persons.

¾ Mount and align the CLV in such a way to prevent the laser beam reflecting off mirrored

surfaces.

¾ Do not open the housing.

(Opening the housing does not deactivate the laser diode).

¾ Observe the laser protection specifications (latest version)

Laser power

The laser operates at a wave length of λ = 650 nm (visible red light). The power output at the reading window is max. 2.8 mW. The emitted radiation is not dangerous to human skin. The product is classified in laser class 2 (laser class II) in accordance with EN 60825-1, IEC 60825-1, and 21 CFR 1040.10 (for publication date, see the warning sign on the device).

Laser warnings

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

• The laser warning symbol on line scanners is positioned beside the reading window on

the front side of the device. The laser warning in GB English/US English is located on the side containing the electrical connections (see Fig. 3-1, Page 3-5.) The additional laser warnings in English applicable to the USA are positioned beside the reading window on the front side of the device and at the bottom of the device.

• The laser warning symbol on line scanners with oscillating mirror is located above the

reading window, on the cover of the mirror. The laser warning in GB English/US English is located on the side containing the electrical connections. The additional laser warnings in English applicable to the USA are positioned below the reading window on the front side of the device and at the bottom of the front side.

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

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

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

If the CLV is installed in a machine/panel with the result that the laser warning labels are no longer visible, additional warnings (not included in the scope of delivery) must be provided on the machine beside the emergence aperture of the laser beam.

Internal protective circuits

The CLV is equipped with monitoring circuits that deactivate the laser diode in the event of a malfunction. No maintenance required to keep this product in compliance with laser class II.

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

A timer (laser timeout) automatically deactivates the laser diode in Reading mode ("Sensor input" and "Serial interface" trigger mode) if the reading interval has not ended after 10 minutes (default setting). However, it does not end the reading interval. In this case, the CLV outputs the message:

"Laser safety timeout"

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

The laser timeout can be set in the range of 1 min to 25 h or deactivated (see Table 6-23,

Page 6-37).

In the "Percentage Evaluation" mode, "Adjusting" mode and "Show CP-limits" 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. In the "Background Analysis" function the laser didoe is constantly pulsed.

Note In the Reading mode, the CLV carries out a distance 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 CLV first scans the bar code with a scan line and then decodes it. In stand-alone configuration, the data is forwarded via the serial host interface (main data interface) to a host/ PC for further processing, or via the CAN interface to the OTS 400 Omni Tracking System. An overview of the CLV functions is provided in Fig. 3-2.

Fig. 3-2: Block diagram: CLV functions

The CLV is equipped with two decoders:

• The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding

bar codes with small code height, bar codes that are dirty or damaged, as well as bar codes that are tilted excessively (azimuth angle)

• The tried-and-tested standard decoder of the CLV series

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

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

The current operating status is indicated by four LEDs.

If the trigger is supplied externally, the "Sensor" switching input instructs the CLV to start the reading process. The five "IN 0" to "IN 4" switching inputs switch the focus position in response to certain events, as an alternative to the autofocus function. The "IN 3" and "IN 4” inputs can also be assigned special functions. The four "Result 1" to "Result 4" switching outputs can be assigned to different functions for displaying the result status and also control external devices, such as a PLC.

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

Operating Instructions Chapter 3

CLV 490 Bar Code Scanner

Product description

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

3.2.1 Autofocus function

The autofocus function enables the CLV to detect the distance of an object during the reading process, without the need for external sensors, and then adjusts the focus position automatically to the reading plane of the bar code. In order to do so, the CLV 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 CLV 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 CLV without any objects present. During the reading process, the CLV then focuses on the object which it recognizes by comparing the actual distance profile to the distance profile of the background. Application: with unobstructed view of the object restricted by other objects that protrude constantly 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 to the CLV are positioned in the reading field at the same time (distance conflict), the CLV focuses on the object that is nearest to but has not exceed its internal focus switchover point. Application: in OTS operation (applications with internal tracking or tracking by the OTC 400 Omni Tracking Controller).

The distance profile of the background can also be displayed in the "CLV-Setup" program. The autofocus range is defined by the aperture angle, the autofocus space, and (in the case of line scanners with oscillating mirror) also by the angle of deflection. 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 lines and is caused by the V-principle of the beam deflection, is optimized as a result (Fig. 3-3).

Measured distance

Optimum focus position: measured distance plus offset for maximum

Depth of field (DOF)

Chapter 3 Operating Instructions

Product description

CLV 490 Bar Code Scanner

In autofocus mode and in combination with the OTS 400 Omni Tracking System the CLV can also use the object height information from the OTS 400 or any other CLV transmitted via the CAN bus.

3.2.2 Event-controlled dynamic focus control

As an alternative to the autofocus function, the CLV can switch its focus position in response to certain events and thus dynamically cover a large reading range. A maximum of eight reading ranges can be defined as distance configurations for this purpose and approached consecutively in reading mode (see Fig. 3-4).

Reading distance

The switch over takes place in response to changes in the object distance (with reads from above: object height detection). The trigger source for the switchover can be:

• A signal combination at the "IN 0" to "IN 4" switching inputs, a command on the host

interface/terminal interface or the integrated timer (e. g. for search mode). Additional in the case of the line scanner with oscillating mirror also the oscillating mirror reversal points. The distance configurations are assigned to the switchover sequence by means of a programmable assignment table.

• In combination with the OTS 400 Omni Tracking System:

Alternatively the object height information from the OTS 400 or any other CLV via the CAN bus.

The distance measurement of the autofocus function can be additionally used to define the distance configurations.

3.2.3 Reading modes in stand-alone configuration

Start/stop mode

During the reading process, only one object is located in the reading field in start/stop mode, i. e. all read bar codes can be clearly assigned to the object. As default, two reading pulse sensors at the beginning and at the end of the reading field control the starting and stopping of the reading process (Fig. 3-5). The size of the reading field is determined by the distance between the two sensors. Alternatively, the reading process can be controlled with
