1.4. Maximum Permissible Exposure and Nominal Ocular Hazard Distance
The Maximum Permissible Exposure (MPE) is the level of radiation to which, under normal
circumstances, persons may be exposed without adverse effects. The MPEs represent the maximum
level to which the eye or skin can be exposed without consequential injury and are related to thewavelength of the laser radiation, the pulse duration or exposure duration, and the tissue at risk.
The MPEs given in the following table are informative and provided so that the integrator can calculate
the Nominal Ocular Hazard Distance (NOHD), perform a risk analysis and inform the user about the safe
usage of the product. However, exposure limits for the eye and the skin of employees in the work place
and the general public are in many countries specified in national laws. These legally-binding national
exposure limits might differ from the MPEs given in the following table.
The NOHD is the distance from the output aperture beyond which the beam irradiance or radiantexposure remains below the appropriate MPE. Importantly, the NOHD is dependent upon the beam
waist size and the divergence of the beam. Therefore, the NOHD is dependent upon the opticalcomponents acting on the beam. The NOHDs given in the following table are relevant only when thelaser is operated with the complete beam delivery system attached. NOHD values are quoted from thefinal focus lens on the scanning head. Further details of the safe use of lasers are given with IEC/ TR
60824-14 "Safety of laser products – Part 14: A user’s guide."

2. General Description
2.1. System overview
The MULTISCAN® VS is a vector laser marking system comprising:• a Radio Frequency (RF) excited, diffusion cooled, CO2 industrial slab laser• a high-speed galvanometer scanning head
• a computer-based controller to position the laser beam on the workpiece• a control panel with QWERTY keypad and VGA display integrated into the main cabinet or with an
optional remote control panel on an umbilical cable
The MULTISCAN® VS system has been specifically designed for very low maintenance operation andminimal user intervention or adjustment. It requires no initial warm-up time or recommended daily
maintenance requirements. Once the system is correctly installed and programmed it can simply beturned on and off to initiate or end marking.

WARNING
Risk of eye damage
Permanent eye damage may result if laser radiation is allowed to enter the eye either directly or
by a reflective surface during procedures involving access to the laser output.
All personnel must wear protective goggles suitable for use with carbon dioxide lasers when thelaser is in a Class 4 operational state.
Personnel not wearing eye protection must be excluded from the area or room containing thelaser.

2.2. Marking principles
When the focused laser beam hits the surface of an infra-red absorbing material, such as ink on card,
the layer of ink is normally ablated or removed from the surface to reveal the contrasting substratematerial as shown diagrammatically in Figure 15.

Figure 15 - Laser ablation using a focused laser beam

Many other materials also absorb at the infrared CO2 laser wavelength and will mark successfully. These
include glass (contrasting micro cracks are formed at the surface), some plastics (contrasting texture orcolour is made by chemical change or melting) and coated metals. Non-absorbing materials, whichcannot be marked with a CO2 laser, include most metals, which reflect at this wavelength, and someplastics, such as polyethylene, which largely transmit the laser radiation.

2. General Description

To mark characters and images, the laser beam is deflected by high-speed galvanometer mirrors
controlled by a computer. The computer also switches the laser beam on and off to form individual
characters.
The computer is connected to a galvanometer control board via a digital interface which sends varying X
and Y co-ordinate deflection values to the vector scanning head. Inside the head, each X and Y deflection
value is converted to a voltage. X and Y galvanometers, (often abbreviated to 'galvos') convert thevoltages into a proportional rotation of their shafts. A mirror is mounted to each shaft to deflect thelaser beam. The galvanometers are mounted on perpendicular axes so that they control the deflectionin the X and Y axis.

Figure 16 - Galvanometer scanning principle

The laser beam enters the head through an input aperture. Once inside, the beam is deflected by mirror
X, then by mirror Y. The beam leaves the head through an objective lens which focuses the beam onto
the surface to be marked. The lens is an 'F-Theta' type so that the focal point is proportional to the angle
of incidence of the beam.
Distortion of the square image field is inherently caused by the path of the beam in the head and by theobjective lens. Without correction, lines would be distorted into curves and the compensation of the
product movement for 'on-the-fly' marking would no longer be accurate. A look-up table downloaded
and stored in the galvanometer control board converts the incoming X and Y values to the correctedvalues.
The marking system is normally installed on a production line or conveyor where product moves past
the system’s scanning head. Marking of items on the production line is normally initiated by a productdetector, which is mounted on the side of the production line adjacent to the system’s scanning head.
By dynamically offsetting the marking by the same amount as the product movement, marking 'on-thefly' is achieved. Accurate measurement and compensation of the product movement is achieved byusing a tachometer (shaft encoder) coupled to the MULTISCAN® VS controller.

2.3. Typical production line installation

WARNING
Risk of eye damage
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous laser radiation exposure. This is a Class 4 (Class IV) laser and the beam isinvisible to the eye. Please review all safety instructions and precautions given in Chapter 1
before attempting to operate the system or perform maintenance procedures.

2. General Description

8906-0248-00 REV 3

Important!
The MULTISCAN® VS is intended to be used for marking materials in an industrial environment.
Use of the equipment for applications other than the intended one constitutes misuse and thelaser manufacturer, Luxinar Ltd does not accept liability for any damage or injury howsoever
caused or arising.

Installation of the MULTISCAN® VS onto a production line requires several peripheral items in addition
to the necessary electrical, cooling and signal interfacing requirements.
These can include:• Safety guarding to protect the operator from exposure to the laser beam or scattered laser
radiation.
• Product detection to initiate marking on the material to be marked.
• Clean compressed air to prevent contamination of the final focus lens on the scanning head.
• Extraction of any fume or debris resulting from the marking process.
A typical installation with a simple ‘conveyor-type’ production line is shown in the following figure.

Product to be marked

Figure 17 - Typical conveyor-type marking installation

Position the user control panel (1) so that it is easily accessible and visible to the operator.
The cooling vents at the base of the system must be unrestricted and allow for free flow of air, required
for system cooling. There must be a minimum of 0.5m clearance between the enclosure and any walls orother obstructions that could impede air flow.
The articulated beam delivery (2) directs the laser beam into the scanning head (3) which generates the
programmed marking pattern on each product to be marked (12). The marking process is triggered by a
product detector (6) that initiates a mark as each product is detected. In this example, a through-beam
detector is shown with its retro-reflector (7).
On variable speed production lines, a feedback signal is required to synchronise the marking speed. The
signal is normally provided by a shaft encoder (10) integrated with the conveyor drive system. Constant
speed lines do not require a feedback signal.
Depending on the material to be marked, it may be necessary to incorporate a fume extractor (8) andnozzle with flexible hose (8A) to remove debris and fume produced by the marking process. If asignificant amount of debris is produced, the final lens will become contaminated, leading to a gradual
2. General Description

10906-0248-00 REV 3

degradation of mark quality and possible damage to the lens. This is prevented by blowing clean
compressed air across the lens to form an air curtain. The compressed air is filtered and regulated down
to an appropriate pressure by an air purification unit (9).
To provide optical protection from the laser beam, guarding must be installed to protect the operator
and other personnel. In this example, a beam shield tunnel is provided which allows free passage of
products past the marking point but prevents operator access and exposure to the laser beam duringmarking. The guarding must also incorporate a beam stop (5) that prevents damage to the guard
material if marking is triggered when no product is present.

2.5. Main cabinet
The main cabinet contains the laser head, DC and RF power supplies, air/liquid or liquid/liquid coolingsystem and electronic control boards with interfaces for integration to the marking station. The
enclosure is made from stainless steel and is sealed to IP66 standard. All cables pass through watertightglands to prevent ingress of moisture.

2.6. Articulated arm beam delivery system
The articulated arm has sealed articulation joints containing pre-aligned beam turning mirrors to direct
the laser beam from the main cabinet to the scanning head.

This should be carried out by a
Luxinar trained engineer.

Other marking system components will also require periodic inspection and cleaning. These include thecompressed air supply filter, the product detectors and the fume extractor filters. The maintenanceinterval for these components will depend on how they are integrated into the marking station.

WARNING
Risk of injury to eyes and exposed skin
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous laser radiation exposure. This is a Class 4 (Class IV) Laser and the beam isinvisible to the eye. Review all safety instructions and precautions given in Chapter 1 before
attempting to operate or service the system.
Always ensure that the marking system is switched off and isolated from the mains supply before
attempting any cleaning or maintenance procedures.

5.2. General cleaning
Always ensure that the system is switched off and isolated from the mains supply before attempting any
cleaning procedures. The system is supplied with two key-switch covers. They must be fitted over the
key-switches before attempting any cleaning or wash-down procedures.
Clean the external surfaces of the system with a mild detergent. It is advisable to use a damp cloth whencleaning the external cabinets and enclosures.
Important!
Take care not to allow water into the main cabinet or the final focus lens beam shroud.

5.3. Cleaning the final focus lens
The only externally exposed optical surface is the scanning head final focus lens. Where a compressed
air supply for the lens protection shroud and fume extractor is correctly installed, the final focus lens
906-0248-00 REV 3

25

5. Routine maintenanceshould rarely need to be cleaned. If cleaning does become necessary, both the compressed air supply
and fume extractor should also be inspected for correct operation and cleanliness of filters.
The most common sources of surface contaminants are fingerprints and airborne contaminants (dust,lint, smoke, etc.). If allowed to remain on optical surfaces, such contaminants will cause absorption andscattering of the laser beam and in extreme cases this may permanently damage the lens and its
coatings. Improper removal of this contamination can also cause permanent damage.

Optics cleaning materials
•
•
•
•

•
•

Lens tissue (first quality)
Tissues (non-perfumed for rough work, wiping hands, etc.)
Disposable lint-free gloves
High purity solvents (preferably anhydrous):➢ Methanol➢ Ethanol➢ Isopropyl alcohol (99.5% purity)
Photographic blower brush
Medicine dropper

Cleaning procedure
1.

Remove the lens protection shroud and the lens but leave the lens in its holder during thisprocedure.
2. Thoroughly wash your hands to remove all oils, perspiration and grit, then rinse them toremove all traces of soap.
3. For added protection, wear lint-free gloves after washing.
4. If there is visible dust, lint or other solid matter on the lens surface, gently blow it off with aphotographic blower brush. Coated optics require careful handling, even for the type labelled"hard-coated".
5. If the lens surface is not badly contaminated, cleaning can be done fairly easily. Fold a fresh
sheet of lens tissue to form a pad several layers thick. Its size will be a compromise between
fully covering the lens diameter and being too large to clean evenly.
6. Using a medicine dropper, apply enough solvent to the pad to just dampen it.
7. Draw the pad across the lens surface in one smooth stroke, using very light pressure, thendiscard the pad.
8. Repeat steps 5 and 6 as required, using a clean pad for each stroke, until the lens surface isclean.
9. Replace the lens into its position on the scanning head and then replace the lens protection
shroud.
10. If the contamination cannot be removed, or if the surface is permanently damaged, replace thelens with a new part having the same specification and orientation.

5.4. Interlocks
It is important to verify the correct operation of external interlocks on a regular basis. In order to do
this, power up the marking system to Ready to Mark status and then open any guard access door
that is fitted with an interlock switch. The system should drop back to Standby status and will display
an interlock fault message.

5.5. Cooling system contamination
If the cooling water is contaminated with bacteria or has been treated with other chemicals it will benecessary to clean the cooling circuit:
The pH value, conductivity and dissolved solids levels can be measured using a portable meter. The
bacterial contamination level can be checked using a test kit. For more information and advice, contact
Luxinar Aftersales.
Pay particular attention to the instructions provided by the manufacturer of the water treatment kit:
5. Routine maintenance26906-0248-00 REV 3

1.

2.
3.
4.
5.
6.
7.

Drain off the contaminated cooling water.
Ensure that disposal of all the materials used in this product is conducted according to all local andnational regulations.
Flush the cooling water circuit with tap water by filling and draining once only.
Mix tap water with deionised water in a 1:1 ratio and fill the cooling water circuit.
Add a NALCO biocide water treatment kit and mix well with the cooling water.
Operate the system for two to four days, then drain off the cooling water.
Flush the cooling water circuit twice.
Refill the cooling system with the approved coolant. See section 6.7.

5.6. Frost protection
If the cooling system or chiller which supplies the cooling for the laser system is located in an area
where the temperature may drop below 0°C, then the cooling circuit must either be equipped with awinter-proof heating tank to prevent the cooling water temperature dropping below 15°C or the coolant
must contain glycol antifreeze. For coolant details refer to 6.7.

5.7. Coolant replacement (all systems)
For coolant draining instructions, see section 7.1.
For coolant refilling instructions, see section 6.7.1.

5.8. Pre-ioniser fuse replacement
The MULTISCAN® VS system has an SR 10i laser head within the main CABINET enclosure. The laser
contains a fuse to protect the pre-ioniser circuit. To replace the fuse, contact Luxinar Aftersales.

5.9. Compressed air supply
A compressed air supply must be connected to the lens protection shroud where there is a possibility ofcontamination of the final lens due to the particulate matter produced as a by-product of the marking
process. Contamination of the final lens will result in poor quality marking or, in the worst case, no markon the product.
The compressed air creates an air curtain with slight over-pressure in the lens protection shroud.
The recommended two-stage air filtering requires regular inspection and maintenance. The interval
between inspections will vary depending on the quality of the initial air supply.
As a basic guide, these filters should be inspected on a weekly basis after initial installation. Where
necessary, replace or clean the filters, referring to the manufacturer’s instructions. Blocked filters may
indicate that the final focus lens has also been contaminated. See section 5.3.
If the filters are found to be clean, the inspection interval can be increased. However, Luxinar
recommends that the maximum interval is no longer than one month.

5.10. Fume extractor
Always switch off the laser system and the extractor and isolate them from the mains power supply
before proceeding with the inspection of extraction filters.
An approved fume extraction unit must be fitted to all installations where particulate matter or fumes
are produced as a by-product of the marking process. The manufacturer of the extraction unit should
recommend the correct filter combination to effectively control the fume produced in the marking
process, which will depend on the materials of the substrate to be marked.
Where the marked product materials are altered or changed after initial installation, then consult
Luxinar Aftersales and the manufacturer of the fume extractor for details of any required change to theextraction filter specification.
The fume extractor filters must be regularly inspected, changed and disposed of in accordance with the
manufacturer’s instructions. In general, this will depend on the construction of the fume extractor, thefilter capacity and the amount of debris produced by the marking process. Where possible use an
extraction system with a built-in filter monitoring device for automatic filter blockage detection.

5. Routine maintenance5.11. Product detectors
Always ensure that the marking system is switched off and isolated from the mains supply before
attempting any cleaning of the product detectors.
Product detectors can be occasionally wiped with a clean damp cloth to remove contamination from theactive surfaces. Take care not to move or disturb the detectors during cleaning as this may affect thecode position on the product to be marked. Do not use abrasive materials as these may damage thedetectors and render them inoperative. See the manufacturer’s instructions for more information oncleaning.
The inspection and cleaning interval will depend on the production line environment. If contamination isfound to be light, the initial daily inspection can be increased up to a maximum of a weekly inspection.

6.2. Mechanical Installation
It is strongly recommended that any personnel who are involved with the installation, operation or
maintenance of this laser equipment should first read and fully understand the contents of the Safety
chapter, Chapter 1.

DANGER
Risk of injury to eyes and exposed skinThis is a Class 4 (Class IV) laser product. All precautions relevant to this class of laser productshould be strictly observed. Use of controls or adjustments or performance of procedures otherthan those specified herein may result in hazardous radiation exposure. Strict compliance withthe safety precautions set out and referred to in this manual and extreme care in use are
essential to minimise the chance of accidental damage to the equipment or personal injury.
Luxinar does not accept liability for any damage or injury howsoever caused or arising.

Before securing any item in a permanent position, it is recommended that the components are firstplaced in their approximate final positions to check for best orientation and location.
The main cabinet should be positioned close to the printing site on the production line. The standard
articulated arm has a reach of approximately 1.2m. Ensure that the control panel is positioned forconvenient operator access and that the safety warning lamps are clearly visible.
In all cases, ensure that the user control panel is positioned so that operator access is convenient andthat the safety warning lamps are clearly visible.
Ensure that there is free flow of air around the main enclosure to allow for unrestricted cooling of thesystem. There must be a minimum of 0.5m clearance between the enclosure and any walls or otherobstructions that could impede air flow. This is especially important for an air-cooled system without anexternal chiller.
During normal operation, the ambient air temperature around the system should be in the range 5–35°C(41–95°F) for an air cooled system or 5–40°C (41–104°F) for a system with external chiller.
In order to fulfil laser safety standard requirements, the main enclosure must be secured to the floorusing 9mm (5/16”) bolts. Two floor brackets are supplied in the accessories kit (part number
114-0008-00) for this purpose. The accessories kit also contains M6 screws to attach the brackets to thesystem.
Do not fit the floor brackets until the rest of the installation is completed. As a temporary measure,apply the front wheel locks to prevent the system from moving during the mechanical installation of the
MULTISCAN® VS.
The floor brackets also act as a positioning reference for the system if it needs to be removed from theproduction line and then subsequently replaced e.g. during cleaning.
Extend the articulated arm and position the scanning head. When mounting the scanning head, ensurethat the beam delivery is not subject to torsional or transverse forces that could cause beam
misalignment or distort the articulations.

6. Installation

6.3. Safety guarding
A safety guard must be fitted around the marking area to contain any direct or reflected laser radiationthat may pose a threat to personnel working near to the marking station. The guard must be designed
and fabricated to match the layout of the production line and position of the marking systemcomponents. An example of a simple tunnel guard is shown in the following figure.

1

Beam entry aperture (scanning head position)

2

Beam stop

3

Product flow direction

4

Guard tunnel entry

5

Guard tunnel exit

Figure 24 - Simple tunnel guard

The design of the tunnel guard must allow free flow of products in the direction of product flow (3). The
length of the guard tunnel must be long enough to prevent operator access to the marking position. The
size and shape of the tunnel entry (4) and exit (5) must be as small as possible to prevent operator
access without impeding product flow. The beam enters the tunnel from the scanning head through anentry aperture (1) cut in the tunnel wall.
The recommended guarding material is 10mm thick clear or smoked polycarbonate sheet.
Polycarbonate is opaque to the infrared wavelength of the laser beam. The guard should cover theworking area as much as is possible so that it is safe for personnel to work in the laser designated area.
If an access door is fitted to the guard wall it must be ‘light tight’ and interlocked to the laser system. Forinterlocking details, see section 8.2.
A beam stop (2) must be fitted to prevent ablation of the guard wall if marking is triggered when no
product is present to be marked. Suitable materials for the beam stop are anodised aluminium or a solidcarbon block of at least 10mm thick.
The size of the beam stop depends on the distance between the marking point and the beam stop
position. As a general rule, the beam stop should be no smaller than 364mm x 364mm for separations of
up to 350mm between the marking point and the beam stop position. For longer separations, contact
Luxinar Aftersales for advice before proceeding. The centre position of the beam stop must be
positioned exactly on the centre line of the beam entry aperture.
Note: A larger beam stop may be required if the scanning head is regularly adjusted for different markpositions on the same production line. For example, to accommodate product type variations.

6.4. Scanning head positioning
When the guarding has been fixed into position, the precise location of the scanning head can befinalised. The scanning head must be clamped into position to ensure it cannot move or be withdrawn
during operation of the system.
Luxinar can provide several scanning head support assemblies depending on the type of installation
environment. These include floor mounted stands and also support devices to fasten directly onto the
production line. When fastening to the production line, include anti-vibration mounts to isolate thescanning head from vibration caused by operation of the production line.
6. Installation

32

906-0248-00 REV 3

A clamp is used to couple the scanning head to the support assembly and is supplied in the accessories
kit. Diagrams showing all dimensions are included in Appendix A. Contact Luxinar Aftersales for detailsof available options.
Important!
It is essential that the products are accurately positioned at the marking position to prevent
variations in mark quality. Variation in the distance between the lens and the product will cause
the mark quality to vary due to a change in spot size at the marking point. The reference distance
between scanning head and product should vary by no more than ± 2mm (± 0.08”) for best
quality marking, though larger characters may support a slightly greater variation. When an open
conveyor is used, it is recommended that guide rails are fitted to constrain the product path andensure that the reference distance remains constant.

6.5. Lens focus adjustment
The focus distance should be set during installation. There should be no requirement to adjust the
distance during normal operation unless required to accommodate changes in product size or shape.
To change or adjust the focus distance:
1. Run a test product down the production line past the scanning head and examine the markproduced.
2. Move the head closer to the product by 1 or 2mm and repeat step 1. Compare the new and oldmark for spot size and mark quality.
3. If the new spot size and mark quality are better than the old, repeat step 2 until it is clear that thelatest spot size and mark quality are worse than the previous one.
4. Move the head away from the product by 1 or 2mm and verify that the new mark is better than theprevious one.
This should be the optimal focus distance for the product.

6.6. Lens protection shroud
The lens protection shroud is used to couple a clean compressed air supply and fume extraction to thescanning head between the lens and the product. The compressed air creates an air curtain to prevent
marking debris from contaminating the lens.
The shroud incorporates a rectangular stainless steel ‘window’. The window improves the efficiency of
the air curtain by reducing the aperture through which the compressed air passes, but the available
marking area is reduced. At the edges of the window, the laser power is reduced because the beam ispartially cut off. Outside this region the beam is completely cut off. A central or offset window may be
used, as shown in the following diagram, to suit different orientations of the galvo head relative to the
product. The offset window is supplied in the accessories kit. The window is held in position by fourscrews accessible from the front of the shroud.

Figure 25 - Lens protection shroud

906-0248-00 REV 3

6. Installation

CAUTION
Risk of optical damage in the laser head
If the laser beam falls onto the stainless steel window frame, it can be reflected back through thelens to a focal position within the laser head. Test marking, and the laser power used during test
marking, must be kept to a minimum to avoid potential optical damage within the head.

6.6.1. Static marking
Create the code to be marked and position it on the user interface screen. Perform a test mark to
confirm the focus position and adjust the scanning head position relative to the product if required.
Check that no part of the code is clipped off or attenuated by the window. For incremental fields, datecodes etc., allow for mark width changes due to character changes in these fields. If the window is not
perpendicular to the mark, clipping at an angle to the mark may occur. Adjust the window as described
below and repeat test marking as required.
If the required code cannot be marked within the available field area allowed by the window aperture,and the code cannot be simplified or made smaller, the window size may be increased to suit. However,this will limit the effectiveness of the air curtain and should be avoided if possible.

6.6.2. On-the-fly marking
Note: When marking, the marking field includes an on-the-fly offset which tracks product movement. Allof the marking, including this offset, must occur within the available marking field.
1. Create the code to be marked and position it on the user interface screen so that it is within thenominal marking field.
2. Enter the expected maximum line speed in the Line settings screen.
3. Optimise the code as necessary to achieve the optimum marking direction, position and sequence.
4. Select Settings > Optimise > Show on-the-fly moves and check that all of thecode is still within the area indicated in the diagrams.
5. Perform a test mark to confirm the focus position and adjust the scanning head position relative tothe product if required. Check that no part of the code is clipped off or attenuated by the window.
For incremental fields, date codes etc., allow for width changes due to character changes in thesefields.
6. If the window is not perpendicular to the mark, clipping at an angle to the mark may occur. Adjust
the window as described in the following section and repeat the test mark.
Note: If the required code cannot be marked within the available field area permitted by thewindow, and the code cannot be simplified or made smaller, the window may be cut out to suit.
However, this will limit the effectiveness of the air curtain and should be avoided if possible.

6.6.3. Window adjustment
The window may be continuously rotated through approximately ± 25°. For adjustments within thisrange:
1. Make the system safe by turning the key switches to the off position.
2. Loosen the screws holding the window in place, adjust the angle of the window and re-tighten thescrews.
If a larger angle is required, the window can be rotated by 90°. To do this:
1. Make the system safe by turning the key switches to the off position.
2. Remove the screws holding the window in place, adjust the angle of the window and re-tighten thescrews.
3. Re-position the window by 90° and refit the screws.
4. Adjust the angle of the window and re-tighten the screws.

To remove particulate contamination, an in-line filter with a pore size of 100µm must be fitted as close
as possible to the laser coolant inlet. The filter should be regularly checked for blockages and cleaned or
replaced where necessary. This is particularly important after bacterial growth has been detected andanti-bacterial treatment applied.
Ensure that the disposal of all the materials used in this product is conducted according to all local andnational regulations.

6.8. Electrical supply connections
The supply characteristics are specified on the system serial number label, which is located on the rear
panel of the system. For full details, see section 2.9.

WARNING
Electrical hazard
The MULTISCAN® VS is a Class 1 Appliance, as defined by 2006/95/EEC Low Voltage Directive EN
60950-1:2006+A2:2013, and as such, must be connected to an electrical earth (ground). See
Chapter 1.

6.8.1. Cable and connector
A dedicated electrical power connection is recommended for the MULTISCAN® VS. The voltage value isset during final test of the system, in accordance with the customer’s order. If the voltage setting isincorrect then contact Luxinar Aftersales for detailed advice.

6.9. Lens protection air supply
The MULTISCAN® VS requires a clean compressed air supply to supply a positive pressure in the lensshroud. This forms an air curtain that prevents dust or debris contamination of the final focusing lens on
the scanning head.
Factory compressed air must be filtered to a very high efficiency to prevent contamination from the air
supply itself. The air should be filtered to an efficiency of 99.9999% at 0.01µm particle size to remove alloil, water and particulate matter.
The air should be supplied at a pressure of approximately 2.4bar (20psig), and at a flow of approximately
15 litres per minute, using 6mm (¼ inch) polyethylene tubing. The tubing connects to the ‘push in’connector on the side of the shroud.
An air purification kit meeting these requirements is available from Luxinar. This consists of a two-stage
regulating filter unit. The first stage regulates the factory line pressure down to 2.4bar (20psig) andfilters bulk material down to 5µm particle size. The second stage contains a high efficiency filter toachieve the 0.01µm particle size specification.
For more information about air purification options contact Luxinar Aftersales.

6.10. Fume extractor
The marking installation should include a fume extraction system to safely remove any fume or debris
produced by the marking process.

CAUTION
Environmental and health hazard
Laser induced reactions during the marking process can release hazardous particulate andgaseous by-products, which may be poisonous. Before carrying out laser processing ensure that
all the applicable local and national safety standards are being followed. These may include
health and safety and environmental pollution standards.

A stand-alone fume extraction system, suitable for a marking installation, is available from Luxinar. The
system consists of a stand-alone fume extractor with a large-bore flexible hose and extraction nozzle
designed for debris and fume removal. It is manufactured by a specialist fume extraction company andis supplied with specialised filters selected for removal of debris and fume for the materials to bemarked.

The scanning head cable is connected between the rear of the scanning head and the main enclosure. It
provides DC power and galvanometer control signals to the scanning head. The standard cable length is
3m and it is supplied complete with connectors.

CAUTION
Risk of damage to the galvanometers
Ensure that the MULTISCAN® VS is switched off before connecting, disconnecting or
reconnecting the cable.

8.5. Product detector J20, J21
A signal indicating the presence of a product at the marking position is required to trigger productmarking. The signal can be provided by:• An external product detector• A product present signal from the production line controller
Where a product detector is used, it should be mounted on an adjustable bracket close to the marking
position. The bracket must allow adjustment of the detector position to ensure that the mark is
positioned correctly on the product.
The detector can be mounted upstream or downstream of the marking position; i.e. detection on theleading or trailing edge of the product or a registration mark on its label. It is recommended that thedetector is mounted on the opposite side of the scanning head to any extraction nozzle used for fume
and/or debris removal. This will help to prevent contamination of the detector, particularly if it is an
optical type.

The MULTISCAN® VS can accommodate two independent product detectors. Dual-detector
configuration is recommended for all flammable products. The dual-detector configuration ensures thatmultiple mark triggering is not possible on stalled, or blocked, production lines, as would be the case fora single detector. If this were allowed to occur, multiple marks could be made in one position on thesame product. The combination of the heat from the focused laser beam and multiple marks in thesame position may create a fire hazard for flammable products.

Figure 38 - Dual-detector configuration

In a dual-detector configuration, the detectors are mounted so that a gate signal from detector 2 isfollowed by a mark trigger signal from detector 1 and before detector 2 sends a new gate signal when it
detects the next product. Figure 38 shows an arrangement for dual-detector operation. Detector 1 (1)and detector 2 (2) are shown detecting the trailing edge of a product (3), which is currently being
marked at the mark position (4). Detector 2 (2) will not detect the next product (3A) until after thecurrent mark has been completed.
Detector spacing depends on the width of the product to be marked and the normal spacing between
products. A spacing of less than one product width is normally recommended for reliable operation. Do
not space the detectors at exactly the width of the product, as interruption of both detectors may bepossible in a stalled or blocked line situation.
Note: When stalled products or blockages are cleared, carefully inspect the products involved to verify
correct mark information and quality.

8.6. Tacho (shaft encoder) J19
A tacho (usually a shaft encoder) can be used to control the code length when marking on a variable
speed production line. It is not required if the MULTISCAN® VS is installed on a constant speed conveyor
section of the production line, where the speed past the marking position does not vary during a
production run.
The shaft encoder unit can be mechanically coupled to a friction wheel or directly to the conveyor drive
shaft in order to provide tacho feedback pulses proportional to the speed of the production line. As the
production line moves faster, more pulses are produced by the shaft encoder.
The recommended pulse-rate required for the MULTISCAN® VS is in the range of 10–50 pulses per
millimetre of production line movement.

Figure 40 - Control panel

An optional remote control panel is available which allows the operator to control the marking systemfrom a few meters further away from the marking station, for example outside a hazardous area wheremachines are operating.
Installation of the remote control panel requires the following additional installation steps:
1. Ensure the system is switched off at the main isolator switch and is disconnected from the mains
supply.
2. Remove the protective covers from the 50-way umbilical cable connectors and from the connectors
on the rear panel of the system main cabinet and the control panel.
3. Connect the 50-pole umbilical cable to the socket on the rear panel then fasten the screw locks
using the thumbscrews.
4. The umbilical cable may be connected to either the front or rear of the control panel, but this may
require exchanging the positions of the cable entry plate and the blanking plate. If required:a. Remove the base plate and disconnect the 50-way IDC cable.
b. Exchange the positions of the cable entry plate and the blanking plate.
c. Re-connect the 50-way IDC cable and replace the base plate.
d. Ensure the seals on all three plates are closed properly and all screws re-fitted whenreassembling the unit.

Appendix B. Calculations for laser safety glasses selection
The Maximum Permissible Exposure (MPE) is the level of radiation to which, under normal
circumstances, persons may be exposed without adverse effects. The MPE represents the maximum
level to which the eye or skin can be exposed without consequential injury and is related to thewavelength of the laser radiation, the pulse duration or exposure duration, and the tissue at risk.
The MPE given in the following table is informative and provided so that the integrator can calculate theNominal Ocular Hazard Distance (NOHD), perform a risk analysis and inform the user about the safe
usage of the product. However, exposure limits for the eye and the skin of employees in the workplace
and the general public are, in many countries, specified in national laws. These legally binding national
exposure limits might differ from the MPE stated in the table.

The NOHD is the distance from the beam focus beyond which the beam irradiance or radiant exposure
remains below the appropriate MPE. Importantly, the NOHD is dependent upon the beam waist size andthe divergence of the beam. Therefore, the NOHD is dependent upon the optical components acting on
the beam. The NOHDs have been calculated for each combination of scan head, scanning lens andoperational wavelength using the maximum radiant power and the maximum pulse energy. These
values represent the worst case when calculating NOHDs and exceed the normal expected operation of
the system. Normal operation is more typically represented by the typical shipment power. The
minimum shipment power represents the minimum guaranteed power when the system ships (seesection 2.9.10).
The calculated NOHDs are only relevant when the specified scanning head and final focus lens are used.
If these are modified or replaced with other optics it is the responsibility of the integrator or end user torecalculate the NOHDs. Further details of the safe use of lasers are given within IEC/ TR 60825-14 ’Safetyof laser products – Part 14: A user’s guide’.
The following table summarises the operating parameters for the MULTISCAN® VS with SC7, SC10 and
SC14 scanning heads.
The irradiance, radiant exposure and optical density have been calculated for the combination of scanhead, scanning lens and operational wavelength using the maximum radiant power and the maximum
pulse energy. These values represent the worst case and exceed the normal expected operational
conditions of the system. The operation is more typically represented by the typical shipment power.
The minimum shipment power represents the minimum guaranteed power when the system ships.
The irradiance, radiant exposure and optical density have been calculated to aid the selection of suitablelaser safety glasses. Further information can be found within BS EN 207: 2017. Other safety measures
may be required to reduce the expected exposure to acceptable levels. Further details of the safe use oflasers are given within IEC/ TR 60825-14 ’Safety of laser products – Part 14: A user’s guide’.
