Chapter 2 Operating Instructions

Safety information

CLV640 Bar Code Scanner

2.2 Intended use

The CLV640 Bar Code Scanner is an intelligent sensor for the automatic recognition and decoding of bar codes on objects e.g. in a conveyor system.

The intended use of the bar code system results from the following description of the function:

• In a reading station, the bar code scanner is installed in a holder, either on the side of a conveyor system (side reading) or above it (reading from above).

• The bar code scanner transfers the reading data via the host interface to a superordinate host computer for further processing.

• The bar code scanner is configured/operated using the SOPAS-ET configuration software that runs on a standard client PC provided by the customer. Communication takes place using RS-232 or Ethernet.

Important Any warranty claims against SICK AG shall be deemed invalid in the case changes to the bar

code scanner, such as opening the housing, this includes modifications during installation and electrical installation or changes to the SICK software.

The bar code scanner is only to be operated in ambient air temperature limit.

2.3 General safety precautions and protection measures

¾ Read the general safety precautions thoroughly and observe them during all bar code

scanner activities. Also observe the warning notices above the operational instructions of each chapter.

2.3.1 Electrical installation work

Risk of injuries due to electrical current!

The optional power supply module CMP400/CMP490 is connected to the power supply (100 ... 250 V AC/50 ... 60 Hz) in connection module CDM420.

¾ Observe current safety regulations when working with electrical equipment.

Important Electrical installation should only be carried out by qualified staff.

Connect or release current linkages only under de-energised conditions.

Wire cross sections and their correct shields have to be selected and implemented according to valid engineering standards.

Operating Instructions Chapter 2

CLV640 Bar Code Scanner

Safety information

2.3.2 Laser radiation of the bar code scanner

Fig. 2-1: Outlet opening of the laser radiation at the reading window (shown here: Ethernet version)

Damage to the eyes through laser radiation!

The bar code scanner operates with an red light laser of class 2. Looking at the laser's light path for a longer period of time can damage the eye's retina.

The entire reading window is the LED radiation outlet opening.

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

¾ Never look directly into the light path (similar to sun light).

¾ Never direct the device's laser beam at the eyes of persons.

¾ When installing and aligning the bar code scanner, avoid laser beam reflections from

reflective surfaces.

¾ Do not open the housing. (Opening does not interrupt the activation of the laser diode

by the reading pulsing.)

¾ Always observe the latest valid version of laser protection regulations.

Important Bar code scanners in series CLV640 operate with a laser of wavelength λ = 655 nm (red

light). The radiation emitted is not harmful 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 (see the warning sign on the device for the date of publication)

Maintenance is not required to ensure compliance with laser class 2.

The bar code scanner displays a black and yellow laser warning sign.

CLV640 Bar Code Scanner

Standard version Ethernet version

Fig. 2-2: Laser warning sign attached to the bar code scanner at delivery

Device CLV640

Laser out radiation (maximum/average) 3.2 mW/ <1.0 mW

Emitted wavelength 655 nm

Pulse duration < 300 μs

Tab. 2-2: Laser Data of CLV640

Important If the bar code scanner is installed in a machine/panelling in such a way that the bar code

scanner's laser warning sign is hidden, additional warning signs in the same language (not included in delivery) have to be attached to the machine next to the outlet opening of the laser radiation!

The bar code scanner works as follows in controlling the laser diodes:

• The bar code scanner has monitoring switches that deactivate the laser diode if irregularities occur in the radiation emission.

• The reading pulse (pulse source) controls the on and off mechanism of the laser diode during the reading process.

• During reading operation with "Sensor" and "Command" reading pulses, each time level (laser timeout) switches off the laser diode automatically after 10 minutes (default settings) when a permanent reading pulse has been started. However, it does not stop the reading pulse.

The reading pulse can be stopped via an appropriate clock signal. The successive reading pulse switches on the laser diode.

• In SOPAS-ET on the "Illumination control" tab you can set or deactivate the laser timeout within a range of 1 ... 1,500 min (= 25h).

During normal reading operation the "Laser" LED lights up when the laser diode is switched on.

When calling up functions via the two buttons of the bar code scanner (aborting normal reading operation), the LEDs have got additional display functions. The "Laser" LED will differ from its original function. It is possible that the "Laser" LED is flashing when Autosetup is selected, although the laser diode is still switched off or the laser diode is switched on, for example, in diagnostic mode (Read Diagn) and the "Laser" LED, however, is not flashing.

2.4 Quick stop and quick restart

The bar code scanner can be switched on or off using the main switch for connection modules CDB620 or CDM420.

2.4.1 Switching off the bar code scanner

¾ Switch off the power supply to the bar code scanner (the connection module)

- or -

Remove (pull out) the 15-pole D-Sub-HD connector of the bar code scanner's connection cable from the connection module.

When the bar code scanner is switched off, the following data is lost:

• Application-specific parameter sets in the bar code scanner that were only saved temporarily in the device

• The last reading result of the bar code scanner

• Daily operating hours counter of the bar code scanner

2.4.2 Switching the bar code scanner back on

¾ Switch the power supply to the bar code scanner (the connection module) back on

- or -

tion-specific configuration of the bar code scanner using the SOPAS-ET configuration software, please read this chapter prior to carrying out any of the tasks.

4.1 Setting up the bar code scanner

The CLV640 Bar Code Scanner consists of a laser scanner (laser diode and lens) with dynamic focus position and an electronic unit with an integrated decoder. The laser scanner and electronic unit are located in a housing. The light exits and enters via a reading window in the industrial-type housing. The bar code scanner (depending on the version) is electrically connected by a cable with a connector or a revolving connector unit with two connections.

For an adaption to on-site space conditions/reading functions three housings are available: a housing with front reading window, a housing with side reading window and a housing with oscillating mirror. Via the integrated angle attachment/oscillating mirror, the laser beam exits through the side reading window at an angle of emergence of 105°. For the oscillating mirror this corresponds to the central position (default settings) of the laser beam perpendicular to the scan direction.

4.6 Bar code scanner methods of operation

The CLV640 Bar Code Scanner is an intelligent sensor system for automatic and non-contact detection and decoding of bar codes. In principle, the codes can be detected on any side of still or moving objects in a conveyor system (single-side reading).

Several bar code scanners can be combined to allow detection of several sides in one passage (multi-side reading).

The bar code scanner creates a scanning line (line scanner) to recognise the codes. In the raster scanner version, the bar code scanner creates eight scanning lines that are moved parallel to each other.

Line scanner with oscillating mirror

The oscillating mirror additionally deflects the scanning line from the home position to both sides, perpendicular to the scanning direction, with a low oscillation frequency. This enables the bar code scanner to scan larger areas for bar codes as well.

Th e leng th of the s cann ing li ne th at is used for the evaluation (reading area height) depends on the reading distance because of the V-shaped light exit.

The light pattern that is reflected by the bar code is recorded, processed and decoded. To control this process, external sensors deliver information via the reading pulse, the object distance and the conveyor speed (increment). The reading results are output to the bar code scanner's data interfaces and forwarded to a host/PC.

The detailed wiring of the bar code scanner and the connections to the host/PC and to the external sensors is described in chapter 6 Electrical installation, page 51.

4.6.1 Reading configuration

The bar code scanner detects bar codes with an adjustable scan frequency.

The bar code scanner can detect codes on still and moving objects.

For more rapid evaluation, the reading range of the scanning line (reading angle: RA value) can be restricted.

Note

The SOPAS-ET configuration software can, among other things, be used to configure the reading angle and the symbol contrast:

Operating Instructions Chapter 4

CLV640 Bar Code Scanner

Product description

4.6.2 Object trigger control

In order to start an object-related reading process, the bar code scanner requires an appropriate external signal (trigger source) for reporting an object in the reading area. The start signal is emitted via an external reading pulse sensor (e. g. photoelectric reflex switch) as standard. As soon as an object has passed the reading pulse sensor, a time window opens in the bar code scanner (“reading gate“) for the reading process.

Alternatively, a command activates the reading process via a data interface or the CAN-SENSOR network. In Automatic Cycle mode, the actual bar code scanner generates the reading gate internally with an adjustable mark-space ratio.

The reading pulse can be ended in a number of ways: With external triggering by the reading pulse source or a command, internally by a timer or an evaluation condition to be met.

Note

The trigger source can be configured using the SOPAS-ET configuration software:

TART/STOP OF OBJECT TRIGGER

4.6.3 Switchable focus position

The focus position can be changed for the CLV640 thus covering a wide reading area.

You can define up to 8 reading areas for the distance configuration which can be started in any order by the lens in reading operation.

Fig. 4-4: Switching the focus for CLV640: Division of the entire reading area in distance

configurations

The focus is shifted by changing the object position (e. g. when reading downwards: detection of object height).

Chapter 4 Operating Instructions

Product description

CLV640 Bar Code Scanner

Trigger sources for the switch-over are:

• Signal at the switching input "Sensor 2" for the max. 2-pole switching

• Command from the host interface or the integrated timer (e.g. search run) for the max.

8-pole switch-over

• Reversal points of oscillation mirror for the bilateral deflection on the line scanner with oscillating mirror chapter 4.6.4 Oscillating mirror control, page 32

The distance configurations of the switching order are assigned via the programmable cross-reference list.

4.6.4 Oscillating mirror control

You can manipulate the position of the scanning line for the line scanner with oscillating mirror (CLV640-6000/CLV640-6120) by configuring the oscillating mirror.

In addition to parking (fixed scanning line position which can be adjusted) or continuous oscillation independent of the reading pulse, controlled operation of the oscillating mirror also enables optimised operation sequences related to the reading pulse:

• n-fold oscillation around an adjustable start position within the reading pulse

• One-shot: one-time deflection (forward and return) per reading pulse from an adjusta-

ble start position

In every oscillation mode, the amplitude can be adjusted separately for each of the two deflection directions. The deflection speed ratio of one deflection direction to the other can be adjusted within the selected periodic time for the entire oscillation sequence.

4.6.5 Increment configuration

The bar code scanner receives information about the conveyor speed from an external incremental encoder, for example. The incremental encoder delivers pulses which are used to determine the current conveyor speed.

The conveyor speed results from the number of impulses and the resolution of the external incremental encoder.

4.6.7 Reading operation mode

There is only one object in the reading field during start/stop operation, i.e. all the read codes should be unambiguously assigned to the object. The start and stop of the reading process control one/two reading pulse sensors at the beginning and at the end of the reading field as standard. The distance between each sensor is determined by the size of the reading field. The reading process can be alternatively controlled with command strings via the data interface. The output of the reading results is carried out either at the end of the reading pulse (the rear edge of the object has left the end of the reading field) or during the reading pulse if certain configurable conditions have been fulfilled.

4.7.3 Buttons on the bar code scanner housing

There are two yellow buttons on the bar code scanner housing in the LED area (see

chapter 4.1.1 Device view, page 24). You can call up predefined functions via these but-

tons.

After changing to the button operating mode you can select one function each by repeatedly pressing the lower button. By pressing the upper button, you can start or stop the selected function. The "TeachIn" function (for matchcode) and "Auto-Setup" stop the bar code scanner automatically. Currently you cannot call up user-defined functions.

The selected function is shown via the corresponding LED below the buttons.

When using both of the buttons the LEDs have different meanings than in normal reading operation:

LED Colour Function

Read Diagn Green Flashes slowly: the "Reading diagnosis/evaluation"

function is selected Flashes rapidly: the "Reading diagnosis/evaluation" function is started

TeachIn Green Flashes slowly: the "TeachIn matchcode" function is

selected Flashes rapidly: the "TeachIN matchcode" function is started

Auto-Setup Green Flashes slowly: the "Auto-Setup" function is selected

Flashes rapidly: the "Auto-Setup" function is started

Adjust Green Flashes slowly: the "Adjusting" function is selected

Flashes rapidly: the "Adjusting" function is started

Userdefined Yellow (momentarily not available)

Tab. 4-6: Meaning of the LEDs during activation of buttons

Important When using the buttons, the "Laser" LED's function differs from its original function in read-

ing operation, the display of the switched-on laser diode.

Use of the buttons

In order to use one of the possible function with the buttons, do as follows:

1. Press the upper button for approx. 3 seconds.

The bar code scanner stops the current reading operation, switches off the LEDs and the bargraph display and changes to the button operating mode. With immediate effect the bar code scanner ignores all the other external reading pulses. No reading results are displayed via the host interface.

The beeper confirms this process with an ascending melody.

The "Read Diagn" function is pre-selected as first function (LED flashes slowly).

2. Repeatedly press the lower button until the LED of the required function flashes. The bar code scanner scans all the possible functions successively without starting them and starts over.

The beeper confirms each step with a sound.

3. Press the upper button once to start the selected function.

The LED flashes faster and the beeper confirms the start with two sounds.

Operating Instructions Chapter 4

CLV640 Bar Code Scanner

Product description

4. Press the upper button again to stop the function.

The LED flashes more slowly again and the beeper confirms the end with two sounds.

The bar code scanner stops the "TeachIn" (for matchcode) and "Auto-Setup" function automatically, when the presented bar code was read successfully. During this procedure, the "Ready" LED flashes in green three times and the beeper confirms it with an ascending melody.

5. In order to return from the button operating mode to the reading operation, press the upper button again for approx. 3 seconds.

The beeper confirms the change with a descending melody.

The "Ready" LED lights up again.

The bar code scanner is ready for reading and waits for a reading pulse.

Further behaviour of the bar code scanner when operated by buttons

• Changing into button operating mode is only possible if no other user is logged onto the bar code scanner for changing the parameters via the SOPAS-ET configuration software. If this is the case, however, a descending melody is started by the beeper when trying to change into the button operating mode. The bar code scanner remains in reading operation.

• In case a user logs onto the bar code scanner in button operating mode, the bar code scanner leaves the button operating mode and restarts the reading operation. The beeper confirms the change with a descending melody.

• If no function is started in button operating mode or if no button operation can be performed after using a function, the bar code scanner returns into reading operation automatically after 30 seconds. The beeper confirms the change with a descending melody.

• The bar code scanner terminates an activated continous function 5 minutes after start. It returns to reading operation automatically. The beeper confirms the change with a descending melody.

• If the bar code scanner could not read the bar code in the "TeachIN" (for matchcode) as well as "Auto-Setup" functions, the "Ready" LED flashes in red for three times. The beeper reports this with a descending melody. After this the bar code scanner remains in button operating mode.

• You cannot switch off or turn down the beeper in button operating mode.

Important In order to avoid data loss, the Micro SD memory card may only be removed and inserted

Product description

CLV640 Bar Code Scanner

4.7.4 Parameter set on the Micro SD memory card (optional)

The bar code scanner stores configured parameter values in the internal PROM as well as on the Micro SD memory card (cloning), provided that this card has been inserted into the bar code scanner. If the bar code scanner needs to be replaced, the memory card enables easy and quick transfer of the parameter set to the new device (see chapter 8.5 Replacing

a bar code scanner, page 76).

into the new device after the respective bar code scanner has been switched off and deenergized. When inserting the memory card, make sure that the contacts point backwards and upwards (towards the inscription "mircoSD" on the box slot).

The memory card is located behind a black rubber cover attached to the bar code scanner.

Fig. 4-7: Micro SD memory card for storing the parameter set

Important To maintain the enclosure rating IP 65, the black rubber cover has to be closed and lie flush

against the device.

As an alternative to the Micro SD memory card in the bar code scanner, the external, optional parameter memory module CMC600 in connection module CDB620/CDM420 may also be used for storing the parameter set. If both the Micro SD memory card and the parameter memory module CMC600 are available, the bar code scanner will load the parameter set from the CMC600.

5.2.4 Exchanging the laser warning sign

The laser warning on the bar code scanner must be in a language that the operators of the unit in which the bar code scanner is integrated can understand.

A set of self-adhesive laser warning signs German/American English and French/American English is included in the delivery.

¾ If necessary, replace the English laser warning sign before operating the bar code scan-

ner.

Fig. 5-2: Exchanging the laser warning sign

5.3 Installation location

The following aspects are relevant for the selection of the installation location:

• Allocation of the scanning line for the bar code

• Reading distance to the bar code and aperture angle α

• Angle alignment of the bar code scanner

• Avoiding surface reflections

• Counting direction of the reading angle (position of the bar code along the scanning

line)

Furthermore, the distance between the bar code scanner and the host computer and the distance to the connection module has to be taken into account (see chapter 6.2 Electrical

installation preparation, page 51 and chapter 5.5.1 Installing connection module CDB620 or CDM420, page 49).

Chapter 5 Operating Instructions

Installation

CLV640 Bar Code Scanner

5.3.1 Allocation of the scanning line for the bar code

The main allocation of the scanning line to the bar code on the object depends on the version of the bar code scanner (line scanner, raster scanner or line scanner with oscillating mirror).

Fig. 5-3: Allocation of the scanning line(s) for the bar code and conveyor system

5.3.2 Reading distance to the bar code and aperture angle α

The maximum distance between the bar code scanner's reading window and the bar code must not exceed the device-specific thresholds.

The usable length of the scanning line that is used for the evaluation (reading area height) depends on the reading distance because of the V-shaped deflection of the beam.

Fig. 5-4: Definition of the reading distance a and the aperture angle α

In the specification diagrams (chapter 10.3 Specification diagrams, page 84) the depth of field is shown depending on the adjustable focus position and the aperture angles used for various resolutions (modul widths).

Operating Instructions Chapter 5

CLV640 Bar Code Scanner

5.3.3 Angle alignment of the bar code scanner

The bar code scanner is optimally aligned if the scanning line almost scans the lines of the bar code in the right-hand angle (90°). Possible code positions that can occur between the scanning line and bar code in all three levels in the room have to be taken into account.

5.3.4 Avoiding surface reflections

If the light of the scanning line(s) vertically meets the surface of the bar code, this can result in disruptive reflections when the bounced back light is received. To prevent this effect, the bar code scanner must be installed in such a way that the light emitted is tilted down relative to the plumb line.

Fig. 5-6: Avoiding surface reflection using the line scanner as an example: Angle between emitting light and bar code (tilted away

from the plumb line)

5.3.5 Counting direction of the reading angle and code angle

The bar code scanner can scan and decode several bar codes with every read.

The location-related reading diagnosis data is determined:

• The reading angle from the reading window to the red scanning line of the deflected scanning beam under which the middle of a bar code is detected can be displayed as an RA (reading angle) value.

• In addition, with the line scanner with oscillating mirror, the deflection angle of the scanning line under which the bar code scanner detects the bar code on the red scanning line can be displayed as a CW value.

The determination of the RA/CW value enables identical bar codes (code type, code length and data contents) to be separated and the bar code data to be assigned to their position on the object.

5.4 Installation of the bar code scanner

5.4.1 Installing the bar code scanner

Damage to the device!

The maximum thread reach of the two blind hole taps M5 is 5 mm (0.2 in). Longer bolts will damage the device.

¾ Use bolts of a suitable length.

1. Preparing base for the installation of the bar code scanner holder, see chapter 5.2.2

Accessories, page 42.

2. Place the object with the bar code at the designated position where the reading should be taken in the bar code scanner's visual range (no conveyor movement).

3. Visually align the bar code scanner to the bar code. Pay attention to the following points:

– With the bar code scanner with the front reading window, ensure that the narrow re-

verse side of the device with the laser warning sign is facing the viewer and is approximately parallel to the bar code plane.

– With the bar code scanner with the side reading window, respectively the line scan-

ner with oscillating mirror, ensure that the wide side panel with the LEDs is facing the viewer and is approximately parallel with the bar code plane.

– During the reading, consider the reading angle, see chapter 5.3.3 Angle alignment

of the bar code scanner, page 45.

– If the bar code's position within the scanning line is relevant for the evaluation, ob-

serve the reading angle's counting direction, see chapter 5.3.5 Counting direction

of the reading angle and code angle, page 46.

4. Installing the bar code scanner holder on the base.

5. Screw M5 bolts through the holder and into the bar code scanner's blind hole taps and gently tighten them.

6. Adjusting the bar code scanner, see chapter 7.6.1 Adjusting the bar code scanner,

5.5 Installing external components

5.5.1 Installing connection module CDB620 or CDM420

Depending on the application, you can install either connection module CDB620 or CDM420. The installation process is the same for both modules.

Important If the PC with the SOPAS-ET configuration software accesses the bar code scanner's auxil-

iary interface (RS-232; 57.6 kbd) via the connection module, the connection module should not be installed more than 3 m (9.84 ft) cable lengths away from the bar code scanner.

1. Install the connection module close to the bar code scanner.

2. Install the connection module in such a way that the opened device can be accessed at any time.

Important

For detailed information about installation and electrical installation, see the operating instructions "Connection Module CDB620“ (no. 8012119, German/English) or "Connection Module CDM420-0001“ (no. 8010004, German/English).

5.5.2 Installing the external reading pulse sensor

If the bar code scanner is triggered by an external reading pulse sensor (photoelectric reflex switch), the sensor has to be installed close to the bar code scanner.

veyed material

b < a

The installation location depends on the distance (a) of the bar code to the front edge of the object. Depending on the application, the sensor should be attached in such a way that bar codes on different sized objects can be fully read during the evaluation (reading gate).

5.5.3 Installing the incremental encoder

An incremental encoder is required for separating bar codes with the same code type and identical content.

The increment impulses have to come from the conveyor system area where the bar code scanner is reading.

1. Install suitable increment encoders near to the bar code scanner, best against the direction of the conveyor system in front of the bar code scanner.

2. Ensure that the incremental encoder has direct and fixed contact with the drive system and that the friction wheel rotates without slipping.

Startup and configuration

CLV640 Bar Code Scanner

7.4 First startup

The SOPAS-ET configuration software optimises the bar code scanner to the reading conditions on site. Starting point for this is the factory default setting which can be adjusted to optimise the bar code scanner. The SOPAS-ET configuration software is used to create an application-specific parameter set which can be loaded permanently into the bar code scanner and saved/archived as a project file (spr file with configuration data) on the PC.

Fig. 7-1: Configuration with SOPAS-ET and storage the parameter set

If the bar code scanner is optionally connected to a Micro SD memory card (see

chapter 4.7.4 Parameter set on the Micro SD memory card (optional), page 40) or connect-

ed to a module with parameter memory mode CMC600, the parameter set is saved permanently to the memory card, or to the CMC600 repectively, with every permanent storage of the parameter set to the bar code scanner.

After the bar code scanner is restarted, the data from the memors card, repectively from the CMC600 is automatically transferred to the bar code scanner. As such, a bar code scanner can be exchanged, for example, without losing configuration data (see chapter 8.5 Replac-

ing a bar code scanner, page 76). If there is a memory card as well as a CMC600, the bar

code scanner takes the parameter set from the CMC600.

7.4.1 Overview of the startup procedure

• Connect data interfaces of the PC and the bar code scanner

• Start the SOPAS-ET configuration software and create a new project file

• Configure the scan assistant (activate PC communication)

• Establish communication with the bar code scanner

• Accept current configuration of the bar code scanner in the project tree

• Log on as an "Authorized client" to the bar code scanner

• Configure the bar code scanner for use

• If necessary, apply the "Event Monitor" diagnosis tool

• Load the optimised configuration into the bar code scanner and save permanently

• Save the project file with the configuration data of the bar code scanner on the PC

8.1 Maintenance during operation

The bar code scanner functions maintenance free. Maintenance is not required to ensure compliance with the bar code scanner's laser class 2.

Important Do not open the bar code scanner's housing. If the device is opened, the SICK AG warranty

shall not apply.

8.2 Cleaning the bar code scanner

Recommendation In or der to m ake us e of the full o ptical re ading capaci ty of th e bar c o de sca nner, t he read ing

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.).

Damage to the eyes through laser radiation!

The bar code scanner works with an red light laser of class 2. Looking at the laser's light path for a longer period of time can damage the eye's retina.

The entire reading window is the LED radiation outlet opening.

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

¾ Never look directly into the light path (similar to sun light).

¾ Never direct the device's laser beam at the eyes of persons.

¾ When installing and aligning the bar code scanner, avoid laser beam reflections from

reflective surfaces.

¾ Do not open the housing. (Opening does not interrupt the activation of the laser diode

by the reading pulsing.)

¾ Always observe the latest valid version of laser protection regulations.

roubleshooting

9 Troubleshooting

This chapter describes how errors at the bar code scanner can be recognised and eliminated.

9.1 Overview of errors and malfunctions which could occur

9.1.1 Installation error

• The bar code scanner has been unsuitably aligned to objects with bar codes (e.g. visual glare)

• Reading pulse sensor has been incorrectly positioned (e.g. internal reading gate opens too late or shuts too early)

• Incremental encoder (optional) positioned incorrectly

9.1.2 Electrical installation error

• Interfaces of the bar code scanner wired incorrectly

9.1.3 Configuration error

• Functions have not been adjusted to the local conditions, e.g. parameters for the data interface set incorrectly

• Device-related limits have not been considered, e.g. reading distance, aperture angle

• Selected trigger source for reading pulse incorrect

9.1.4 Malfunctions during operation

• Start/Stop operation: External reading pulse is missing, more than one object is in the reading area

• Device error (hardware/software)

9.2 Detailed malfunction analysis

9.2.1 LEDs on the bar code scanner

The following statuses can, among other things, be read from the LEDs on the bar code scanner's housing (see chapter 4.7.2 LEDs on the bar code scanner's housing, page 37):

• Reading reliability (Bar graph, diagnostic mode)

• Ready

• Status of the reading result (Result)

• Data trafic on the Host-, Aux- and CAN-interface

The LEDs can display possible malfunctions or errors. Please refer to the system information for further details.

Chapter 9 Operating Instructions

Troubleshooting

CLV640 Bar Code Scanner

9.2.2 System information

The bar code scanner displays errors in various ways. The error output is hierarchised and always allows a detailed analysis:

• Communication errors can occur while transferring telegrams to the bar code scanner. In this case, the bar code scanner returns an error code.

• Error codes are written into a status protocol for errors which occur during a reading (chapter 9.3 Status protocol, page 80).

9.3 Status protocol

Important The status protocol remains even after switching the bar code scanner off and on again.

The bar code scanner differentiates between four error types:

• Information

• Warning

• Error

• Fatal error

The bar code scanner only saves the last five entries for each of the error types.

9.3.1 Displaying the status protocol using the SOPAS-ET configuration software

In order to display the status protocol, the SOPAS-ET configuration software has to be online and connected to the bar code scanner.

1. Connect the SOPAS-ET configuration software with the device.

2. Open the project tree CLV640, S

ERVICE, SYSTEMSTATUS, register tab SYSTEMINFORMATION.

9.4 SICK Support

If an error cannot be eliminated, it is possible that the bar code scanner is defective. The bar code scanner cannot be repaired by the user, meaning that it is not possible to re-establish functions after a failure. However, the bar code scanner can be rapidly replaced by the user. See chapter 8.5 Replacing a bar code scanner, page 76.
