1.2 Laser Classes
The Complete Laser System
The laser itself is classified as class 4 laser system. Up to the beam outlet the closed laser
system acts as a class 1 laser system in normal operation
1
.
If the beam outlet including the object to be marked is shielded appropriately, the complete,
closed laser system acts as a class 1 laser system in normal operation
1
and no additional
protection is required for operation. The shielding prevents emerging of laser radiation or laser
beam reflexes.
Note The shielding is not included in the scope of delivery!
Laser
radiation
The beam path must always be closed, also if there is no product in front of
the laser lens.
The Laser Source
The CO2 laser - hereinafter called laser - is operated in pulsed or continuous wave operation.
The laser itself is classified as class 4. It produces invisible (infrared) radiation which is extremely dangerous for the eye and dangerous for the skin.
In pulsed operating mode the pulse frequency adjusts between 50 Hz and 20 kHz. The actual
operating mode and pulse frequency depends on the application.
The following values can be reached (no specification):
max. average power density energy density
at the beam outlet
up to 1.5 x 106 W/m
2
7 x 102 J/m2 (at 1 kHz and
50 % duty cycle
in focus
up to 5 x 10

Caution!
radiation
As soon as the closed shielding or the housing of the laser are opened anywhere the complete laser system is set to class 4!
In that case appropriate measures have to be taken in order to protect people
working in the laser area against too high radiation. Make sure to meet the local regulations regarding protection against laser radiation.

Caution with modifications!
EN 60825, part 1, »Safety of laser systems«, section 4.1.1 says:
If a modification by the user to a laser system previously classified in accordance with this standard leads to a change of its performance data and/or its
intended use that person or organization performing the modification is responsible for a new classification and labeling of the laser system.
02/15 - Rev. AE 9
Page 12
Table of Contents
1.3 Intended Use
The laser system must only be used for the treatment of material surfaces. The surfaces
are locally heated by intensive class 4 laser radiation and are modified thereby. These systems
are mainly applied for marking of product surfaces (expiry dates, batch printing, serial numbers,
etc.).
The radiation produced by the laser system is of high energy and therefore improper use represents a danger to persons or objects!
Laser
radiation
• Never expose human beings or animals to laser radiation!
This might result in severe burns of eyes or skin.
• Never expose flammable materials to laser radiation!
Always ensure appropriate shielding of the laser beam! Errors during
marking on flammable materials (e.g. paper) might cause fires. Take suitable safety measures by installing e.g. smoke or fire detectors, or similar!
• Never expose reflecting surfaces to laser radiation!
The reflected laser beam may cause the same dangers - in individual cases even greater dangers - as the original laser beam.
• Never expose unknown materials to laser radiation!
Some materials (e.g. polyethylene, polypropylene, glass) are easily penetrated by the laser beam, although they seem to be opaque for the human
eye.
• Danger of explosion!
Make sure that the laser area is free of explosive materials or vapors!
• For safety reasons arbitrary modifications or changes to the laser
system are forbidden!
If a modification made by the user to a previously classified laser system
leads to a change of its performance data and/or its intended use that person or organization performing the modification is responsible for a new
classification and labeling of the laser system. The person or organization
is then regarded as »manufacturer«.
• The laser system must be operated with open laser and/or open beam
delivery system by specially trained personnel only!
Make sure that the laser protection rules are always observed!

1.4 Maintenance and Service
The maintenance tasks described hereinafter should only be carried out by especially trained
personnel. The service tasks are exclusively to be carried out by service personnel of VIDEO-
JET or one of their representatives. During these works the laser system has to be operated in
class 4. The Unfallverhütungsvorschrift (Accident Prevention Regulations) 46.0 »Laser Radi-
ation« (BGV B2) says that the responsible trade cooperative association and the authority responsible for occupational safety (Trade Supervisory Office) have to be given notice of class
3B or 4 laser systems before initial operation.
Important • Give notice of the laser system to the responsible trade cooperative asso-
ciation and the Trade Supervisory Office before initial operation.
• Have a person responsible for the safety of the laser system trained as laser safety officer and inform the trade cooperative association in writing
about this person.
Note:
In order to facilitate safe performance of all necessary maintenance and service tasks without
assistance and to ensure highest safety for the operating and maintenance personnel we offer
special training seminars.
• Training for technicians:
The trainee gains the knowledge required to perform all maintenance and service tasks at
the laser system safely and professionally without assistance.
• Combined training:
In addition to the knowledge gained during the training for technicians the person is trained
as laser safety officer. This training is accepted by the trade cooperative association (see
above).
Ask for free information material!
Please be aware that (in Germany) the personnel operating the laser system must be instructed according to §12 of the Health and Safety at Work Act and §4 BGV A1 (Prevention Principles) at least once a year.

1.5 Safety Devices and Warning Lights
The complete laser system includes various safety devices and warning lights which shall prevent damages to people or objects. There must not be any alterations to safety devices nor
warning lamps (see section "Laser Classes" on page 8)!
Safety Devices
Key-operated switch prevents operation of the laser system by unauthorized people.
The "switch" is closed by entering a password in the Touch Control. Make sure that the login information is available to authorized
personnel only!
Beam shutter is located within the marking head and prevents the emission of la-
ser radiation.
Interlock switch(es) open(s) the safety circuit. The marking process is stopped imme-
diately. If several interlock switches are connected: Laser radiation cannot be emitted if at least one interlock switch is opened.
All safety doors, protective covers, etc. must be safeguarded by
interlock switches. Number and position of the interlock switches
are system-specific.
For wiring the safety circuit single wires must be used and they
must be laid separately to avoid the risk of short-circuits.
For the marking process all interlock switches must be closed. In
an interlock switch is open the message "Error Interlock open" is
displayed in the software.
After closing the interlock switch the marking process can be continued after a delay of 5 seconds.
We recommend the interlock monitoring module for proximity safety switches AES 1235 in combination with the magnetic guard door
BNS 33 and the actuating magnet BPS 33 by Schmersal.
The interlock circuit must be checked regularly.
Note The input »Interlock« is to be used exclusively for connecting external inter-
lock switches. It is not intended for controlling the laser system. For that purpose please use the input »Shutter Lock«.
Warning Lights
Red light ("bumper") on the head of the laser system lights up when the emission of
laser radiation is possible.

1.6 Dangers to Eyes and Skin
The laser system produces class 4 laser radiation. Infrared laser radiation is not visible for
the human eye. Therefore eyes and skin are endangered through high-energy laser radiation.
High irradiation causes an extreme local heating and burning of the tissue. The eyes are
subject to special risks. High radiation intensity causes a local heating and burning of the cornea and thus a reduction or loss of sight!
People within the area of the laser must wear suitable safety
goggles against laser radiation while carrying out maintenance,
adjustment or service work at the open laser housing and/or open
beam delivery system!
Never look directly into the laser beam!
Suitable safety goggles provide protection against direct, specularly reflected or diffusely scattered laser radiation.
Suitable safety goggles are:
• designed for the wavelength range of the CO
laser of 10.6 μm. See name plate of the laser
2
system.
Careful with confusions!
Safety goggles for other lasers, e.g. Nd:YAG laser, do not provide adequate protection
against radiation of a CO
laser!
2
• designed for the power range of the laser. Values of maximum average power:
Videojet 3020 15 W
• are designed for pulse and continuous wave operation.
The skin can withstand higher radiation intensities than the eye. However - depending on the
radiation period and radiation intensity - the tissue is destroyed through burns. Therefore pro-
tect your skin by wearing adequate protective clothing! Avoid any exposure of your skin to
the laser radiation! Avoid the laser beam to get in contact with your clothing!

Laser
radiation
The high output power of a class 4 laser can inflame various materials.
Therefore, while performing maintenance and service work at the open laser housing and/or open beam delivery system, make sure that fire protection measures were taken before starting the works!
Paper (circuit diagrams, leaflets, posters on the walls, etc.), curtains which
are not impregnated fire retardantly, wooden boards or similar flammable
materials can easily be inflamed by direct or reflected laser radiation.
Make sure that the working area of the laser system is free from contain-
ers with flammable or explosive solvents or cleaning agents! Unintended exposure of a container to intensive invisible laser radiation might
easily cause fires or explosions.
1.10 Electrical Safety
The laser system was designed in accordance with the general rules of technology including
regulations EN 60950-1 and EN 60825-1.
Caution During works at the open laser housing alive components are accessible!

1.11 Decomposition Products
Caution When treating materials with laser radiation decomposition products are pro-
duced which are dangerous to health!
Through vaporization of materials fine dust and vapors are produced which
might include hazardous decomposition products depending on type and
composition of the respective materials.
Therefore we highly recommend to install an fume extractor according to the
respective requirements which is equipped with special dust and activated
charcoal filters to ensure that the decomposition products are sucked off
where they are produced.
Protect yourself and your colleagues against hazardous decomposition
products!
A fume extractor also prevents contamination and gradual destruction of optical elements of
the beam delivery system by dust particles. We offer different fume extractors as accessories.
1.12 Cleaning Agents
Caution The housing of the laser system is made of PC/ABS (polycarbonate with
acrylonitrile butadiene styrene). This material can be corroded by aggressive
substances.
To clean the housing use only a damp cloth (water or mild detergent solution).
Acetone must only be used for cleaning the lens surface and must not get in
contact with the housing!

3 Description of the Laser System
3.1 The Marking of the Product Surface
The marking of the product surface is performed by the effect of intense laser radiation on the
product material.
The laser beam is focussed onto the product surface and heats up the topmost layer of the material, which causes a color change or a vaporization of the topmost dye layer.
Two movable mirrors deflect it such that it passes over the lines of the active job on the product.
The lines are divided into vectors (X and Y coordinates). The line up of vectors produces a
marking on the product, the laser »writes« on the product surface.
When the laser beam jumps from one stroke to the next (2) the laser is switched off and the
product is not marked.

5.3 Cleaning the Focusing Module
The focusing module is located at the front of the laser system (bottom side).
It may be contaminated by dust or floating particles. Contamination of the focusing module can
lead to damages of the focusing module and gradually reduce the quality of the marking. Therefore the lens has to be cleaned regularly.
Generally just the outwardly facing side of the focusing module has to be cleaned, but check
both sides for contamination and clean them, if necessary.
Important As with all optical components the focusing module is an object of highest and
sophisticated design.
Slightest damages of the surface might (in the long term) result in unusability
of the component or reduction of marking quality. Any contaminants must only
be removed by means of a cotton tip and acetone!
Make sure that no contaminants enter the marking head while cleaning the focusing module!
To clean the focusing module you need:
• Optics cleaning paper
• Acetone
• Protective gloves
Important Wear protective gloves during the complete procedure!

Threshold value of the amount of inhaled particles that can be handled by the
body of persons who
permanently deal with this material job related:
For Thorium Fluoride Dust with 1 μm Particle Size
(This value is getting higher significantly with bigger particles.
Particles bigger than 20 μm can not be inhaled any more.) 136 mg
Threshold value of the amount of inhaled particles that can be handled by the
body of persons who does
not deal with this material job related:
For Thorium Fluoride Dust with 1 μm Particle Size
(This value is getting higher significantly with bigger particles.
Particles bigger than 20 μm can not be inhaled any more.) 3 mg
Effects of overexposure:
ZnSe - Effects are not known, but some Zinc and Selenium can be formed,
such as: Zinc Oxide - Chills and fever. Selenium and Compounds - Acute
exposure might produce sternal pain, cough, nausea, pallor, coated tongue,
gastro-intestinal disorders, nervousness and/or conjunctivitis. A garlic odor of
the breath or sweat may occur.
Thorium - eventually cancer producing, because of its radio activity. But no
impact has been recognized through inhalation of less than 270 - 540 mg/year.
One assumes that from this point the risk enlarges linear to the inhalation. The
exposure through the continuing contact with a lens for 2000 hours/year is less
than the exposure that occurs when your teeth are x-rayed two times, you
make a trans-continental flight or fume 1/3 of a cigarette/day. Inorganic Fluorides - normally an irritant and toxic. Inhaling can be the cause for irritations of
the respiratory tract and the mucosa, asthma attack, increased salivation,
thirst, sweating, vomitus and colic.

8. Special Protection Information
Type of respiratory protection required:
NIOSH approved respiratory with fume type cartridge
Ventilation:
In case of vaporization leave the room and allow the dust to settle. Clean all
surfaces if the room has ventilation, allow for several air changes. Locate
exhaust near location of ZnSe processing or use if failure by melting is likely.

9. Special Precautions
Handling and storage precaution:
If material is to be machined, ground or polished, processes should be done
wet so as to minimize dust which could result in inhalation. Good work practices such as keeping hands clean and not letting slurry splash significantly
should be followed so that transferal to mouth by contamination on the hands
or clothing followed by ingestion will not occur. Wash hands and face thoroughly after handling material and before eating.
If parts are dropped or otherwise broken, sweep up pieces which may have
sharp edges as one would clean up broken glass and safely TRANSFER TO
DISPOSAL CONTAINER: large pieces may have salvage value.
