Safety information
2.2 Intended use
The CLV640 Bar Code Scanner is an intelligent sensor for the automatic recognition and de-
coding 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 func-
tion:
•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 superordi-
nate host computer for further processing.
•The bar code scanner is configured/operated using the SOPAS-ET configuration soft-
ware 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
¾Read 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
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 accord-
ing to valid engineering standards.
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.
¾Observe current safety regulations when working with electrical equipment.

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 pub-
lication)
Maintenance is not required to ensure compliance with laser class 2.
The bar code scanner displays a black and yellow laser warning sign.
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 li-
ght 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.
¾Never look directly into the light path (similar to sun light).
¾Never direct the device's laser beam at the eyes of persons.
¾When installing and aligning the bar code scanner, avoid laser beam reflections from
reflective surfaces.
¾Do not open the housing. (Opening does not interrupt the activation of the laser diode
by the reading pulsing.)
¾Always observe the latest valid version of laser protection regulations.

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 irreg-
ularities 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 set-
tings) 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 read-
ing 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).

•"Laser" LED:
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 Auto-
setup 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, how-
ever, 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 mod-
ules CDB620 or CDM420.
2.4.1 Switching off the bar code scanner
¾Switch 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 connec-
tion 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
¾Switch the power supply to the bar code scanner (the connection module) back on
- or -
Connect the 15-pole D-Sub-HD connector of the bar code scanner's connection cable
to the connection module.
The bar code scanner starts up using the most recent permanently saved configura-
tion. The daily operating hours counter is reset.
