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!
The Laser Source
The Ytterbium fiber laser - hereinafter called laser - is operated in pulsed 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.

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.
05/17 - Rev. AB 9

Chapter 1
Safety Instructions
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. See also section
"Marking of Highly Reflective Material" on page 11.
• 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!

Safety Instructions
1.3.1 Marking of Highly Reflective Material
When marking highly reflective material there might be a feedback of radiation into the laser.
In this case the system switches to fatal error mode. Especially if the working distance was not
set correctly this may lead to irreversible damage of the system.
Observe the following when marking highly reflective materials:
• Make sure that the working distance is set correctly before marking any reflecting material.
Use a weakly reflecting material for testing, e.g. laminated paper.
• When marking reflecting material try not to mark in the center of the marking field. Position
the product so that the marking is in the edge of the marking field.
• When setting the laser power start with the maximum value and reduce the power until the
marking result is satisfying. If no marking is visible at maximum power the material cannot
be marked using this laser.
If the laser system has switched to fatal error mode, a reset is required: Switch the laser system off and on again and observe the above mentioned notes.

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. In Germany, the DGUV Regulation 11 »Laser Radiation« says that the responsible
trade cooperative association and the authority responsible for occupational safety (Trade Supervisory Office) have to be given notice of class 3R, 3B or 4 laser systems before initial operation. Please make sure to comply with your local regulations.
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).

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.
Make sure that the key is withdrawn and 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.
Interlock switches can safeguard safety doors, protective covers,
etc. Number and position of the interlock switches are systemspecific.
For the marking process all interlock switches must be closed. 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.
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

Safety Instructions
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 fiber laser of 1055 - 1075 nm. See name plate of
the laser system.
Careful with confusions!
Safety goggles for other lasers, e.g. CO
radiation of a fiber laser!
• designed for the power range of the laser. Values of maximum average power:
Videojet 7220 12 W
Videojet 7320 24 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!

Caution Fire and explosion hazard if there are flammable materials or explosive
A password is required for changing the marking field (if the password protection has been activated in the software). The password can be changed subsequently by a user authorized for
the corresponding user level.
We explicitly point out that the person who will fulfil a modification of the marking field,
will assume the full responsibility for any consequential damages and problems!
If, as a result of the modification, the laser beam gets accessible the complete laser system is set to class 4 (see section "Laser Classes" on page 8).

1.9 Fire and Explosion Hazard
Chapter 1
Safety Instructions
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, EN 62368-1, EN 60204-1 and EN 60825-1.
Caution During works at the open laser housing alive components are accessible!
Make sure that rules and regulations for works on alive components are always observed!
All works at the open laser housing, especially at electrical components,
must only be performed by specially trained personnel!

Safety Instructions
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.
A fume extractor according to the respective requirements which is equipped
with special dust and activated charcoal filters must be installed to ensure that
the decomposition products are removed from where they are produced.
When treating materials with laser radiation the national and relevant regulations for air purification at work must be observed. Those regulations can result in further, detailed requirements regarding the performance of the fume
extractor or the air recirculation to the workplace.
This can be the case marking different plastics, e.g. POM (polyoxymethylene), ABS (acrylonitrile butadiene styrene), SAN (styrene acrylonitril copolymer), HDPEand LDPE (polyethylene), PAN (polyacrylonitrile), PBT
(polybutylene terephthalate) or different tool steels, e.g. with chromium additions.
Marking those materials the formation of carcinogenic substances cannot be
ruled out. This can result in the prohibition of the air recirculation to the workplace, i.e. the fume extraction system must lead the exhaust air outside into
the atmosphere.
The company operating the system for treatment of material surfaces using
laser radiation is responsible for meeting the local codes and regulations. Additionally, the safety instructions of the operating instructions must be observed.
Protect yourself and your colleagues against hazardous decomposition
products!
An exhaust unit also prevents contamination and gradual destruction of optical elements of the
beam delivery system by dust particles. We offer different exhaust units as accessories.

Description of the Laser System
3 Description of the Laser System
3.1 Functioning of a Vector-Scanning Laser System
The fiber laser (1) working in pulsed operation produces an infrared invisible laser beam with
small diameter. The laser beam is expanded by means of a telescope (2) and reaches the
marking head (3).
Two movable mirrors deflect it such that it passes over the lines of the opened template 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.
The calculation of vectors and the control of the laser is performed by the Advanced Controller
Card (ACC) in the supply unit.
The deflected laser beam is focussed onto the product surface (6) by a laser scan lens (4).
Generally the marking is produced at the focus of the lens (5).

3.2 The Laser Beam Source
Ytterbium-doted glass fibres are used as beam source for the laser system in a power range
of up to 10 W resp. 20 W. The fibres are pumped by laser diodes.
3.3 The Marking Head
After the laser beam is expanded by the telescope it reaches the marking head. Two movable
mirrors are located inside the marking head which deflect the laser beam vertically and horizontally.
The X and Y axes of the coordinate system of the marking field are defined by the position of
the marking head. A translation or rotation of the marking head also translates or rotates the
axes of the coordinate system. X and Y axes in relation to the marking head are defined as
displayed in the following figure:

Chapter 3
Description of the Laser System
3.4 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.
The symbols and characters which shall be marked on the product are subdivided into vector
strokes (1). Each vector stroke is again subdivided into smaller vectors.
When the laser beam jumps from one stroke to the next (2) the laser is switched off and the
product is not marked.
Figure 3-3: Strokes and jumps
3.5 The Laser Parameters
Parameters are used to adapt the laser system to different materials. These parameters have
to be determined and adjusted for each application in order to achieve the best possible marking quality.
Determining the correct parameters requires profound knowledge and experience, because
the parameters highly depend on the application and the material which shall be marked. In
case of questions please contact us.
The parameters for individual materials are combined in parameter sets. Parameter sets can
be generated and altered either with the handheld or the Smart Graph software. For detailed
information on the parameters please refer to the respective chapters.

4 Operating the Laser System
4.1 Operation of the Laser System
The laser system is built up modularly. Depending on the laser system installed in your premises there are several ways to generate a marking template and starting the marking process.
The laser system can be operated:
• via the handheld or
• using a PC with the Smart Graph software.
Handheld The handheld gives you easy access to the controls of the
laser system. It is connected to the supply unit via the network
interface. One handheld can be used for different supply units.
It permits you to:
• generate or alter a marking job.
• generate and alter templates (limited).
• adjust the laser parameters.
• configure the laser system.
Smart Graph software The Smart Graph software runs on your personal computer
under Windows. With the Smart Graph software you can
access the full range of fonts, logos and tools to create even
complex layouts and preview the marking on your monitor. In
addition you can access all laser parameters and system settings.
Using the Smart Graph software you can transfer the created
templates directly to the supply unit.

Page 34
Chapter 4
Operating the Laser System
4.2 Marking Elements
The following elements must be defined in order to mark a product:
Marking Contents The marking content defines the layout of the marking, e.g. text
elements, logos, serial numbers, fonts, etc.
Parameter Set Parameter sets adjust the laser system to the respective material
of the product. A parameter set contains e.g. information on the
laser power or the marking speed.
Product Registation The product registration contains all data necessary to detect the
product and to trigger the marking process.
Positioning Data The positioning data defines the positioning and the size of the
marking on the product.
The combination of the four elements marking content, parameter set, product registration and
positioning within a template offers the possibility to adapt the marking to different marking
tasks in a very short period of time.
Examples:
• You want to mark a certain text on synthetic material instead of paper. Hence you change
your parameter set from »paper« to »synthetic material«.
• You want to change the position of the marking on you product. For that you just change the
positioning data directly in your template or in the user interface »Laser Operation« under
»Marking settings«.

5.3 Cleaning the Laser Scan Lens
The laser scan lens is located at the marking unit. It may be contaminated by dust or floating
particles. Contamination of the laser scan lens can lead to damages of the laser scan lens and
gradually reduce the quality of the marking. Therefore the lens has to be cleaned regularly.
Generally just the outwardly facing side of the laser scan lens has to be cleaned, but check both
sides for contamination and clean them, if necessary.
Important As with all optical components the laser scan lens 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 (part of the accessory box)!
Make sure that no contaminants enter the marking head while cleaning the laser scan lens!
To clean the laser scan lens you need:
• Optics cleaning paper
• Acetone
• Protective gloves
Important Wear protective gloves during the complete procedure!

cess.
X4D.9 SHUTTER_CLOSED This signal is set if the beam shutter is
closed.
X4D.8 ERROR This output is LOW active. The system is
stopped immediately if an error occurs
during the marking process (e.g. laser
overtemperature). The output is reset
with the next start (but may be set again
immediately if the error was not cleared).
X4D.7 BAD This output is LOW active and indicates
that the last marking was not completed
due to a warning or error. The output is
reset with the next trigger signal.
X4C.9 GOOD This output is LOW active and indicates
that the last marking has been completed
without a warning or error. The output is
reset with the next trigger signal.

"1" signal voltage 8.5 V to 30 V
Input current at 12 V/24 V 4/10 mA
Min. signal length without software filter 2 μs
Electrical insulation none
The supply voltage for the non-insulated inputs can be changed between 12 V and 24 V using
the jumper X17 on the ACC:
X17 closed: 12 V
X17 open: 24 V
Thus encoders and sensors requiring a voltage supply of 12 V or 24 V can be used.

Voltage Supply (if PLC is used)
The inputs and outputs are supplied via terminals X4B.3 and X4B.9 in order to separate the
marking system galvanically from the PLC.
System Status
The following signals are processed:
• SYSTEM_READY
• MARKING
• READY_TO_MARK
• ERROR
Control
The system is controlled via:
• START
• STOP
• TRIGGER
Light Barrier
• is connected to TRIGGER
• voltage supplied by marking system
• no galvanical separation
Incremental Encoder
• connected with both tracks and index track
• voltage supplied by marking system
• no galvanical separation
Note Shielded cables are to be used for connecting peripheral equipment (e.g.
encoders, sensors, controllers).
Using unshielded cables may result in interferences and thus incorrect markings.
