result in death or severe (crippling) injury.
WARNING
refers to a possibly dangerous situation. If it is not avoided, it could result in death
or severe injury.
CAUTION
refers to a possibly dangerous situation. If it is not avoided, it could result in slight
or minor injury. May also be used to warn of damage to property.
NOTICE
refers to handling tips and other particularly useful information. This does not signify a dangerous or harmful situation.
WARNING

the instructions could result in minor or major injuries to the eyes (blindness) or to
the skin, together with damage to property.
2.2 Laser Classes
The Complete Laser System
The laser itself is classified as class 4 laser system according to EN 60825-1. Up
to the beam outlet the closed laser system acts as a class 1 laser system in
normal operation1.
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 operation1 and no additional protection is required for operation. The shielding pre-
vents emerging of laser radiation or laser beam reflections.
NOTICE
The shielding is not included in the scope of delivery!
09/17 - Index: AD [EN]

WARNING
The beam path must always be closed, also if there is no product in front of the
laser lens.
1.
Normal operation does not include service, maintenance nor repairs.
The Laser Source
As laser beam source (hereinafter called laser) a CO2 laser in continuous wave
operation is used. 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.
The laser can be modulated with a frequency between 50 Hz and 20/25/160 kHz
(10/30/60 W). The actual frequency depends on the application.
The following values can be reached (no specification):

WARNING
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 excessive radiation! For information on appropriate safety measures we offer special training seminars, see also section »Maintenance and Service«.
CAUTION
... with modifications!
EN 60825, part 1, »Radiation 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.
09/17 - Index: AD [EN]
WARNING
The pilot laser can be used for simulation or adjustment without the CO2 laser. Also in this case you must wear laser safety goggles for protection against CO2 laser radiation.

a.
In this case the CO2 laser is switched off via the software. Due to the laser safe-
ty regulations safety goggles must be worn.
2.3 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
(dates, batch printing, serial numbers, etc.).
WARNING
The radiation produced by the laser system is of high energy and therefore improper use represents a danger to persons or objects!
The laser system must only be installed in production sites with restricted access.
Examples for Improper Use and the Resulting Risks
• 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, extinguishers, 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 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 mark-
ing system are forbidden and result in loss of warranty!
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«.
In this case a new risk assessment is required.
09/17 - Index: AD [EN]
2.4 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 Videojet Technologies Inc. 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
Videojet 3140/3340/3640/2 Safety Instructions
9
Page 10
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.
NOTICE
Give notice of the laser system to the responsible trade cooperative association
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 if the system is operated in class 4 for maintenance purposes.
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!
2.5 Safety Devices and Warning
Lights
The complete laser system includes various safety devices and warning lights
which shall prevent damage to people or objects. There must not be any alterations to safety devices nor warning lamps (see section "Laser Classes [} 7]")!
Safety Devices
Key switch The key 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 The beam shutter is located within the laser head and
prevents the emission of laser radiation.
Laser safety circuit
(short: Door circuit)
Emergency stop circuit
(Interlock circuit)
The door circuit monitors the safety housing of the
system. If the door circuit is opened, the beam shutter
is closed.
The safety controller monitors the beam shutter. If the
shutter does not close, the beam source is switched
off. Thus the system remains in laser class 1 even if
the housing is open.
The emergency stop circuit directly deactivates the
power supply module and thus eliminates any danger.

Warning lights
Red lights
"Laser emission"
Additional warning
lights
The red lights on the control panel of the supply unit
and on the marking unit light up when the emission of
laser radiation is possible. The functioning of these
lights is monitored. In case of malfunction the system
cannot start the laser.
Additional lights can be connected as external emission displays (system-specific).
NOTICE
When installing the laser make sure that at least one of the warning lights is always visible.
2.6 Dangers to Eyes and Skin
The laser system produces class 4 laser radiation. This radiation is emitted in the
infrared range and invisible to the human eye.
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!
WARNING
People within the area of the laser must wear suitable safety goggles against laser radiation while carrying out maintenance, adjustment or service work on lasers with 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 a CO2 laser of 10.6 μm (optional 9.3 or
10.2 μm). See ID label of the laser system.
Careful with confusions!
Safety goggles for other lasers, e.g. Nd:YAG lasers, do not provide adequate
protection against radiation of a CO2 lasers!
• designed for the power range of the laser. Values of maximum average pow-
er:
Videojet 3140 : 10 W
Videojet 3340 : 30 W
Videojet 3640 : 60 W
In individual cases these values might be exceeded by up to 50 %.
For 60 W systems power values of up to 150 W are possible.
• designed for continuous wave operation.
09/17 - Index: AD [EN]
Videojet 3140/3340/3640/2 Safety Instructions

Page 12
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 protect your skin by wearing adequate personal protective equipment! Avoid any exposure of your skin to the laser radiation! Avoid the
laser beam coming in contact with your clothing!
WARNING
The pilot laser can be used for simulation or adjustment without the CO2 laser. Also in this case you must wear laser safety goggles for protection against CO2 laser radiation.
a.
In this case the CO2 laser is switched off via the software. Due to the laser safe-
ty regulations safety goggles must be worn.
2.7 Adjustment/Modification of the
a
Marking Field
Via the software the marking field of the laser can be modified in such a way that
the laser beam can possibly be directed to the shielding or onto other components or parts. Thus, surfaces exposed to irradiation can be damaged or destroyed.
WARNING
If, as a result of the modification, the laser beam becomes accessible the complete laser system is set to class 4 (see section "Laserklasse [} 7]").
WARNING
Fire and explosion hazard if there are flammable materials or explosive atmospheres within the area of the laser beam.
Appropriate safety measures must be taken if the laser is to be operated in explosive atmospheres.
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 damage and problems!
2.8 Noise Hazard
During the marking process high-frequency noises in the range of 70 to 80 dBA
are produced.
09/17 - Index: AD [EN]
NOTICE
Protect your ears and wear a suitable hearing protection.

2.9 Safety Information for Zinc
Selenide Lenses
CAUTION
The laser scan lens consists of coated zinc selenide and contains an extremely
small amount of the radioactive substance thorium. This applies to all CO2 laser
marking systems available on the market.
Zinc Selenide
This material contains components which are dangerous to health!
Zinc selenide is toxic when inhaled or ingested. Dust may lead to irritation of the
eyes and the respiratory system. Do not eat, drink or smoke while handling zinc
selenide. Wash hands thoroughly afterwards.
For detailed information see safety data sheet in the chapter "Appendix".
Thorium
Thorium is a potential health hazard when inhaled or ingested. The thorium layer
is embedded within other layers within the lens. Thus no radioactive material can
escape from the coating as long as the lens is intact. Avoid any surface scratches
of the lens.
There is no danger of radiation during normal handling and cleaning of the
optical system!
In case of a broken lens...
...do not inhale material particles! In case of breaking of the laser scan lens
please collect the fragments wearing gloves (avoid raising dust when sweeping
up the pieces), pack the fragments into a closed plastic bag and send them back
to Videojet Technologies Inc. for disposal.
Maintenance of the Laser Scan Lens
Information concerning the maintenance of the laser scan lens can be found in
section “Cleaning the Laser Scan Lens [} 43]” (see chapter "Maintenance").
Please contact us if further information is required.

2.10 Fire and Explosion Hazard
WARNING
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 containers with
flammable or explosive solvents or cleaning agents! Unintended exposure of
a container to intensive invisible laser radiation might easily cause fires or explosions.
2.11 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.
DANGER
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!

2.12 Decomposition Products
WARNING
When treating materials with laser radiation decomposition products are produced
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), HDPE
and 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!
09/17 - Index: AD [EN]
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.

3.5 Cooling
The laser system is cooled by air. The internal cooling system is designed to supply sufficient cooling.
Make sure that the cooling air can be sucked in and blown out freely and that
there is sufficient air exchange at the installation site to ensure heat dissipation.
3.6 Fume Extractor
In order to remove marking residues which might be dangerous to health a fume
extractor must be installed.
The fume extractor is to be installed such that marking particles are sucked off directly at the place of the formation to prevent the accumulation of dust particles
which gradually destroy optical components of the laser system. Make sure that
there are no air leaks.
We offer fume extractors as accessories. If a fume extractor is part of the complete delivery please find further information in the enclosed operation manual of
the fume extractor

4 Description of the Laser System
4.1 Function Principle of a Vector-
Scanning Laser System
The laser (2) working in pulsed or continuous operation produces an infrared invisible laser beam with small diameter. The laser beam is expanded by means of
two-lens telescope (3).
The expanded beam reaches the marking head (4) where 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 controller card in the supply unit (1).
The deflected laser beam is focussed onto the product surface (7) by a laser scan
lens (5). Generally the marking is produced at the focus of the lens (6).
09/17 - Index: AD [EN]
4.2 The Laser Beam Source
A sealed-off CO2 laser serves as beam source for the laser system. Inside the laser source CO2-molecules are stimulated by a high-frequency voltage to emit infrared laser radiation.
Videojet 3140/3340/3640/4 Description of the Laser System
25
Page 26
4.3 The Marking Head
Two movable mirrors are located inside the marking head. They deflect the laser
beam vertically and horizontally according to the current template.
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:
4.4 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.
4.5 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.
09/17 - Index: AD [EN]
Videojet 3140/3340/3640/4 Description of the Laser System
26
Page 27
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 using the software. For detailed information
on the parameters please refer to the manual of the marking software.
4.6 The Structure of the Laser
System
The laser system consists of the supply unit (1) and the marking unit. The marking unit comprises the laser head (2) and the marking head (3). The supply unit is
controlled via:
• the Handheld
• the Smart Graph software on a PC
• the Touch PC
• the CLARiTY Laser Controller
Optionally, a beam turning unit can be installed between laser head and marking
head.

5 Operating the Laser System
5.1 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 start
the marking process.
The laser system can be operated via:
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.
• open and edit templates (limited).
• create and edit laser parameters.
• configure the laser system.
Smart Graph Software The Smart Graph software runs on your personal com-
puter under Windows. The software offers all possibilties
of the handheld. In addition you can create complex layouts, import logos, change fonts and edit all laser parameters, etc.
Using the Smart Graph software you can transfer the created templates directly to the supply unit.
Touch Control The Touch Control Software runs on a touch PC under
Windows.
Using the Touch Control you can easily create, edit, select and mark templates.
CLARiTY Using the CLARiTY Laser Controller you can easily se-
lect and mark templates.
For creating and editing of marking jobs CLARiSOFT is
required.
5.2 Marking Elements
The following elements must be defined in order to mark a product:
09/17 - Index: AD [EN]
Videojet 3140/3340/3640/5 Operating the Laser System
35
Page 36
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 registration The product registration contains all data necessary to de-
tect the product and to trigger the marking process.
Positioning 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 your product. For that you
just change the positioning data directly in your template or in the user interface »Laser Operation« under »Marking settings«.

We offer special training seminars for maintenance and service personnel. In
case of questions please contact Videojet Technologies Inc. one of their representatives.
6.3 Cleaning the Laser Scan Lens
The laser scan lens is located at the marking head. It may be contaminated by
dust, floating particles in the air or other substances formed by the marking process. Contamination of the laser scan lens can lead to damage of the laser scan
lens and gradually reduce the quality of the marking. Especially using higher laser
power a contamination of the laser scan lens can result in damage to other components of the marking system. 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.
WARNING
The laser scan lens consists of coated zinc selenide. This material contains components which are dangerous to health!
Cleaning must only performed wearing latex protective gloves! In case of contact
of the laser scan lens with the skin, wash the respective part of skin with water
and soap immediately! Avoid any surface scratches of the laser scan lens! Do not
inhale material particles! In case of breaking of the laser scan lens please pack
the fragments into a closed plastic bag and send them back to us.

CAUTION
As with all optical components the laser scan lens is an object of highest precision and sophisticated design!
Slightest damage 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 optics cleaning paper and acetone.
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
NOTICE
Wear protective gloves during the complete procedure!

Assignment Variant 1 (SPM-16A)
NOTICE
Assignment Variant 1 guarantees performance level "d" according to EN13849-1
for the interlock circuit. Prerequisite is the correct wiring of the interlock circuit using appropriate safety switches and cables:
For the interlock switches positively opening contacts according to IEC60947-5-1
must be used (e.g. SCHMERSAL AZ 16-02ZVRK). The supply lines must have
individually shielded cores (e.g. HELUKABEL LiY-TPC-Y (4x2x0.5 or 2x2x0.5) P#
21357 or 21355.
The MTTF calculation used for achieving performance level "d" is based on the
following assumptions:
1) Number of operating hours/day = 21 (3 shift operation with 1 hour break)
2) Number of operating days/year = 310 (365 days minus sundays/holidays)
3) Cyle time in seconds = 28,800 (8 hours 3 shift operation with 1 cleaning cycle
per shift)
4) Resulting average number of cycles per year = 813.75

8.3.1 Power Supply Connector for the Customer Interface
(Connector X28)
The power supply of the customer interface can either be supplied by the customer (opto-decoupled potential-free connection) or internally with 12 V or 24 V (nonisolated).
The jumpers X19 (yellow) and X20 (green) are used for configuration.
Potential-free configuration
For the potential-free configuration (power supply by the customer) the jumpers
must be set as follows:
External supply +12 V to +24 V (potential-free):
09/17 - Index: AD [EN]
The external supply of 12 or 24 V +/- 10 % max. 50 W is to be connected to
X28.7 (+) and X28.8 (-).
Non-isolated configuration
For the non-isolated configuration (internal power supply) the jumpers must be
set as follows.
In this case X28.7 and X28.8 are not connected.
Internal supply +12 V (non-isolated):
