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 -

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.
