2 Safety Instructions 2.1 Symbols Used DANGER refers to an immediately impending danger. If the danger is not avoided, it could 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 refers to the emission of laser radiation and therefore to a possibly dangerous situation. Please comply exactly with the safety instructions! Failure to comply with 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. 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 prevents emerging of laser radiation or laser beam reflections.

NOTICE The shielding is not included in the scope of delivery!

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 The CO2-laser (hereinafter called laser) is operated in pulsed or continuous wave operation respectively. 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 can be adjusted between 50 Hz and 20 kHz. The actual pulse frequency depends on the application. The following values can be reached (no specification): at the beam outlet

average power density up to 1.5 x 106 W/m2

in focus

up to 5 x 109 W/m2

energy density 7 x 102 J/m2 (at 1 kHz and 50 % duty cyclea) 3 x 106 J/m2 (at 1 kHz and 50 % duty cyclea)

a.

duty cycle: The ration between the period of laser emission and the operation .

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 too high radiation! For being able to take appropriate 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 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

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 a.

In this case the CO2 laser is switched off via the software. Due to the laser safety 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.). The radiation produced by the laser system is of high energy and therefore improper use represents a danger to persons or objects!

WARNING 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, 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. See also section "Marking of Highly Reflective Material". · 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 marking machine are forbidden! If a modification made by the 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. · The laser system with open covers and/or with open beam delivery system must be operated by specially trained and qualified personnel only! Make sure that the laser protection rules are always observed!

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 , the Unfallverhütungsvorschrift (Accident Prevention Regulations) 46.0 »Laser Radiation« (BGV B2) says that the responsible trade cooperative association and the authority responsible for



9

occupational safety (Trade Supervisory Office) have to be given notice of class 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! Please be aware that (in ) 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.

2.5 Safety Devices and Warning Lights The complete laser system includes various safety devices and warning lights which can give alarm signals and prevent damages to people or objects. There must be no alterations to safety devices nor warning lamps (see section "Laser Classes [} 7]")!

Safety Devices Key-switch

Beam shutter


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! The beam shutter is located within the laser head and prevents the emission of laser radiation.


10

Interlock switch(es) (Safety switch)

One or more interlock switches open the external safety circuit when activated. The marking process is stopped immediately. If several interlock switches are connected: If at least one interlock switch is opened no laser radiation can be emitted. All safety doors, protective covers, etc. must be safeguarded by interlock switches. Number and position of the interlock switches are system-specific. Single wires must be used for wiring the interlock switches and they must be laid separately in order to avoid short circuits. For the marking process all interlock switches must be closed. If an interlock switch is opened the message "Interlock open" is displayed in the software. After closing the interlock switch the marking process can be continued after a delay. 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.

Warning Lights Red light Red light "Laser emission" Additional warning lights

The red light on the marking head lights up when the emission of laser radiation is possible. The red light on the control of the supply unit lights up when the emission of laser radiation is possible. Additional lights can be connected as external emission displays (system-specific).

NOTICE When installing the laser make sure that at least one of the 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 for 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!



11

Suitable safety goggles provide protection against direct, specularly reflected or diffusely scattered laser radiation. Suitable safety goggles are: · designed for the narrow wavelength range of the CO2 laser of 10.6 μm (optional 9.3 μm). See name plate of the system. Carful with confusions! Safety goggles for other lasers, e.g. Nd:YAG lasers, do not provide adequate protection against radiation of a CO2 laser! · designed for the power range of the laser. The maximum output power can be as follows: Videojet 3130: 10 W Videojet 3330: 30 W · designed for pulse and continuous wave operation. The pulse frequency of the laser system adjusts between 50 Hz and 20 kHz, depending on the application. 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 to get in 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 a.

In this case the CO2 laser is switched off via the software. Laser safety regulations always recommend wearing safety goggles.

2.7 Adjustment/Modification of the 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 gets accessible the complete laser system is set to class 4 (see section "Laser Classes [} 7]").

WARNING Fire and explosion hazard if there are flammable materials or explosive atmospheres within the area of the laser beam. A is required for changing the marking field (if the protection has been activated in the software). The can be changed subsequently by a authorized for the corresponding level.



12

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!

2.8 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 us for disposal

4 Description of the Laser System 4.1 Function Principle of a VectorScanning 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 es 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).

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 3130/3330/4 Description of the Laser System

25

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.



26

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 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 (2). The supply unit is controlled via: · the handheld or/and · the Smart Graph software on a PC or · the SOI software on the Touch PC. The marking head (3) is attached to the marking unit. Optionally a beam turning unit is available.

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 starting the marking process. The laser system can be operated: · via the handheld and/or · using a PC with the Smart Graph software or · using a Touch PC with the SOI 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 7. 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. SOI software

The "Simple Operator Interface" (SOI) runs on PC under Windows 7 or on a Touch PC. Using the SOI software you can easily select and edit jobs and start the actual marking process.

5.2 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 registration The product registration contains all data necessary to detect the product and to trigger the marking process.


Videojet 3130/3330/5 Operating the Laser System

32

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 you product. For that you just change the positioning data directly in your template or in the interface »Laser Operation« under »Marking settings«.
