2 Safety Instructions

2.1 Symbols Used DANGER

refers to an immediately impending danger. If the danger is not avoided, it couldresult in death or severe (crippling) injury.

WARNINGrefers to a possibly dangerous situation. If it is not avoided, it could result in deathor severe injury.

CAUTIONrefers to a possibly dangerous situation. If it is not avoided, it could result in slightor minor injury. May also be used to warn of damage to property.

NOTICErefers to handling tips and other particularly useful information. This does not sig-nify a dangerous or harmful situation.

WARNINGrefers to the emission of laser radiation and therefore to a possibly dangerous sit-uation. Please comply exactly with the safety instructions! Failure to comply withthe instructions could result in minor or major injuries to the eyes (blindness) or tothe skin, together with damage to property.

2.2 Laser Classes

The Complete Laser SystemThe laser itself is classified as class 4 laser system according to EN 60825. Up tothe beam outlet the closed laser system acts as a class 1 laser system in nor-mal operation 1.

If the beam outlet including the object to be marked is shielded appropriately, thecomplete, closed laser system acts as a class 1 laser system in normal oper-ation 1 and no additional protection is required for operation. The shielding pre-vents emerging of laser radiation or laser beam reflections.

NOTICEThe shielding is not included in the scope of delivery!

09/13 - Index: AA [EN] 7Videojet 3130/3330/2 Safety Instructions



WARNINGThe beam path must always be closed also if there is no product in front of thelaser lens.

1. Normal operation does not include service, maintenance nor repairs.

The Laser SourceThe CO 2-laser (hereinafter called laser) is operated in pulsed or continuous waveoperation respectively. The laser itself is classified as class 4. It produces invisi-ble (infrared) radiation which is extremely dangerous for the eye and dangerousfor the skin.

In pulsed operating mode the pulse frequency can be adjusted between 50 Hzand 20 kHz. The actual pulse frequency depends on the application.

The following values can be reached (no specification):

average power density energy densityat the beam outlet up to 1.5 x 10 6 W/m 2 7 x 10 2 J/m 2 (at 1 kHz and

50 % duty cycle a)in focus up to 5 x 10 9 W/m 2 3 x 10 6 J/m 2 (at 1 kHz and

50 % duty cycle a)a. duty cycle: The ration between the period of laser emission and the operationterms.

WARNING As soon as the closed shielding or the housing of the laser are opened anywherethe complete laser system is set to class 4.

In that case appropriate measures have to be taken in order to protect peopleworking in the laser area against too high radiation! For being able to take appro-priate measures we offer special training seminars, see also section »Mainte-nance 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 accordancewith this standard leads to a change of its performance data and/or its intendeduse that person or organization performing the modification is responsible for anew classification and labeling of the laser system

WARNINGThe pilot laser can be used for simulation or adjustment without the CO 2 laser. Al-so in this case you must wear laser safety goggles for protection against CO 2 la-ser radiation. a

a.

In this case the CO 2 laser is switched off via the software. Due to the laser safe-ty regulations safety goggles must be worn.




2.3 Intended UseThe 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 modi-fied 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 im-proper use represents a danger to persons or objects!

WARNINGLaser 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 markingon flammable materials (e.g. paper) might cause fires. Take suitable safetymeasures 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 caseseven greater dangers - as the original laser beam. See also section "Markingof Highly Reflective Material".

· Never expose unknown materials to laser radiation!Some materials are easily penetrated by the laser beam, although they seemto 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 machine are forbidden!If a modification made by the user to a previously classified laser systemleads to a change of its performance data and/or its intended use that personor organization performing the modification is responsible for a new classifica-tion and labeling of the laser system. The person or organization is then re-garded as »manufacturer«.In this case a new risk assessment is required.

· The laser system with open covers and/or with open beam delivery sys-tem must be operated by specially trained and qualified personnel only!Make sure that the laser protection rules are always observed!

2.4 Maintenance and ServiceThe maintenance tasks described hereinafter should only be carried out by espe-cially trained personnel.

The service tasks are exclusively to be carried out by service personnel of Video- jet Technologies Inc. or one of their representatives. During these works the laser

system has to be operated in class 4 . In Germany, the Unfallverhütungsvorschrift(Accident Prevention Regulations) 46.0 »Laser Radiation« (BGV B2) says thatthe 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. Please make sure to comply withyour local regulations.

NOTICEGive notice of the laser system to the responsible trade cooperative associationand 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 thisperson if the system is operated in class 4 for maintenance purposes.

In order to facilitate safe performance of all necessary maintenance and servicetasks without assistance and to ensure highest safety for the operating and main-

tenance personnel we offer special training seminars.· Training for technicians:

The trainee gains the knowledge required to perform all maintenance andservice tasks at the laser system safely and professionally without assistance.

· Combined training:In addition to the knowledge gained during the training for technicians the per-son is trained as laser safety officer. This training is accepted by the trade co-operative association (see above).

Ask for free information material!

Please be aware that (in Germany) the personnel operating the laser systemmust be instructed according to §12 of the Health and Safety at Work Act and §4BGV A1 (Prevention Principles) at least once a year.

2.5 Safety Devices and WarningLightsThe complete laser system includes various safety devices and warning lightswhich can give alarm signals and prevent damages to people or objects. Theremust be no alterations to safety devices nor warning lamps (see section " LaserClasses [ } 7]")!

Safety Devices

Key-switch The key-switch prevents operation of the laser systemby unauthorized people. Make sure that the key iswithdrawn and available to authorized personnel only!

Beam shutter The beam shutter is located within the laser head andprevents the emission of laser radiation.




Interlock switch(es)

(Safety switch)

One or more interlock switches open the external

safety circuit when activated. The marking process isstopped immediately. If several interlock switches areconnected: If at least one interlock switch is openedno laser radiation can be emitted.

All safety doors, protective covers, etc. must be safe-guarded by interlock switches. Number and position of the interlock switches are system-specific.

Single wires must be used for wiring the interlockswitches and they must be laid separately in order toavoid short circuits.

For the marking process all interlock switches must beclosed. If an interlock switch is opened the message"Interlock open" is displayed in the software.

After closing the interlock switch the marking processcan be continued after a delay.

We recommend the interlock monitoring module for proximity safety switches AES 1235 in combinationwith the magnetic guard door BNS 33 and the actuat-ing magnet BPS 33 by Schmersal.

Warning Lights

Red light The red light on the marking head lights up when theemission of laser radiation is possible.

Red light"Laser emission"

The red light on the control panel of the supply unitlights up when the emission of laser radiation is possi-ble.

Additional warninglights

Additional lights can be connected as external emis-sion displays (system-specific).

NOTICEWhen installing the laser make sure that at least one of the the warning lights isalways visible.

2.6 Dangers to Eyes and SkinThe laser system produces class 4 laser radiation. This radiation is emitted in theinfrared range and invisible for the human eye.

High irradiation causes an extreme local heating and burning of the tissue. Theeyes are subject to special risks: High radiation intensity causes a local heatingand burning of the cornea and thus a reduction or loss of sight!

WARNINGPeople within the area of the laser must wear suitable safety goggles against la-ser radiation while carrying out maintenance, adjustment or service work on la-

sers 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 narrow wavelength range of the CO 2 laser of 10.6 μm (op-

tional 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 adequateprotection against radiation of a CO 2 laser!

· designed for the power range of the laser. The maximum output power canbe 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 appli-cation.

The skin can withstand higher radiation intensities than the eye. However - de-pending on the radiation period and radiation intensity - the tissue is destroyedthrough burns. Therefore protect your skin by wearing adequate personal protec-tive equipment! Avoid any exposure of your skin to the laser radiation! Avoid thelaser beam to get in contact with your clothing!

WARNINGThe pilot laser can be used for simulation or adjustment without the CO 2 laser. Al-so in this case you must wear laser safety goggles for protection against CO 2 la-ser radiation. a

a. In this case the CO 2 laser is switched off via the software. Laser safety regula-tions always recommend wearing safety goggles.

2.7 Adjustment/Modification of theMarking FieldVia the software the marking field of the laser can be modified in such a way thatthe laser beam can possibly be directed to the shielding or onto other compo-

nents or parts. Thus, surfaces exposed to irradiation can be damaged or de-stroyed.

WARNINGIf, as a result of the modification, the laser beam gets accessible the complete la-ser system is set to class 4 (see section " Laser Classes [ } 7]").

WARNINGFire and explosion hazard if there are flammable materials or explosive atmos-pheres within the area of the laser beam.

A password is required for changing the marking field (if the password protectionhas been activated in the software). The password can be changed subsequentlyby 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 dam-ages and problems!

2.8 Safety Information for ZincSelenide Lenses

CAUTIONThe laser scan lens consists of coated zinc selenide and contains an extremely

small amount of the radioactive substance thorium. This applies to all CO 2 laser marking systems available on the market.

Zinc SelenideThis material contains components which are dangerous to health!

Zinc selenide is toxic when inhaled or ingested. D ust may lead to irritation of theeyes and the respiratory system. Do not eat, drink or smoke while handling zincselenide. Wash hands thoroughly afterwards.

For detailed information see safety data sheet in the chapter "Appendix".

ThoriumThorium is a potential health hazard when inhaled or ingested. The thorium layer is embedded within other layers within the lens. Thus no radioactive material canescape from the coating as long as the lens is intact. Avoid any surface scratchesof the lens.

There is no danger of radiation during normal handling and cleaning of theoptical system!

In case of a broken lens......do not inhale material particles! In case of breaking of the laser scan lensplease collect the fragments wearing gloves (avoid raising dust when sweepingup the pieces), pack the fragments into a closed plastic bag and send them back

to us for disposal

Maintenance of the Laser Scan LensInformation concerning the maintenance of the laser scan lens can be found insection “ Cleaning the Laser Scan Lens [ } 37]” (see chapter "Maintenance").

Please contact us if further information is required.




2.9 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 takenbefore starting the works!

Paper (circuit diagrams, leaflets, posters on the walls, etc.), curtains which are notimpregnated fire retardantly, wooden boards or similar flammable materials caneasily be inflamed by direct or reflected laser radiation.

Make sure that the working area of the laser system is free from containers withflammable or explosive solvents or cleaning agents! Unintended exposure of a container to intensive invisible laser radiation might easily cause fires or explo-sions.

A fume extractor according to the respective requirements must be installed!

2.10 Electrical SafetyThe laser system was designed in accordance with the general rules of technolo-gy including regulations EN 60204-1 »Safety of machinery - Electrical equipmentof machines« and EN 60825-1 »Safety of laser products«.

DANGERDuring works at the open laser housing alive components are accessible.

4 Description of the Laser System

4.1 Function Principle of a Vector-Scanning Laser SystemThe laser (2) working in pulsed or continuous operation produces an infrared in-visible 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 mirrorsdeflect 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 vectorsproduces 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 control-ler card in the supply unit (1).

The deflected laser beam is focussed onto the product surface (7) by a laser scanlens (5). Generally the marking is produced at the focus of the lens (6).

4.2 The Laser Beam Source A sealed-off CO 2 laser serves as beam source for the laser system. Inside the la-ser source CO 2-molecules are stimulated by a high-frequency voltage to emit in-frared laser radiation.

09/13 - Index: AA [EN] 25Videojet 3130/3330/4 Description of the Laser System



4.3 The Marking HeadTwo 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 theposition of the marking head. A translation or rotation of the marking head alsotranslates or rotates the axes of the coordinate system. X and Y axes in relationto the marking head are defined as displayed in the following figure:

4.4 The Marking of the ProductSurfaceThe marking of the product surface is performed by the effect of intense laser ra-diation on the product material.

The laser beam is focussed onto the product surface and heats up the topmostlayer of the material, which causes a color change or a vaporization of the top-most dye layer.

The symbols and characters which shall be marked on the product are subdividedinto vector strokes (1). Each vector stroke is again subdivided into smaller vec-tors.

When the laser beam jumps from one stroke to the next (2) the laser is switchedoff and the product is not marked.

4.5 The Laser ParametersParameters are used to adapt the laser system to different materials. These pa-

rameters have to be determined and adjusted for each application in order to ach-ieve the best possible marking quality.




Determining the correct parameters requires profound knowledge and experi-

ence, because the parameters highly depend on the application and the materialwhich shall be marked. In case of questions please contact us.

The parameters for individual materials are combined in parameter sets. Parame-ter sets can be generated and altered using the software. For detailed informationon the parameters please refer to the manual of the marking software.

4.6 The Structure of the Laser SystemThe laser system consists of the supply unit (1) and the marking unit (2). The sup-ply 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 turningunit is available.

5 Operating the Laser System

5.1 Operation of the Laser SystemThe laser system is built up modularly. Depending on the laser system installed inyour premises there are several ways to generate a marking template and start-ing 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 thenetwork interface. One handheld can be used for differ-ent supply unitsIt 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 com-

puter under Windows 7. The software offers all possibil-ties of the handheld. In addition you can create complexlayouts, import logos, change fonts and edit all laser pa-rameters, etc.

Using the Smart Graph software you can transfer the cre-ated 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 ElementsThe 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 respectivematerial of the product. A parameter set contains e.g. in-formation 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.

09/13 - Index: AA [EN] 32Videojet 3130/3330/5 Operating the Laser System



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, productregistration and positioning within a template offers the possibility to adapt themarking 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. Henceyou 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 inter-face »Laser Operation« under »Marking settings«.

trigger inputs enabled

trigger inputs disabled

The release affects all trigger sources:

· AUTO, TRIGGER

· PROGRAM (Allprint Basic)

Input Specification

"0" signal voltage 0 V bis 5 V"1" signal voltage 8.5 V bis 30 V

Input current at 12 V/24 V 4/10 mAMin. signal length without soft-ware filter

2 μs

Electrical insulation none

The supply voltage for the non-insulated inputs can be changed between 12 Vand 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 beused.
