General Information

Fundamental Operation of the System.

This vector laser marking system is based on a radio frequency excited, diffusion-cooled CO₂ Slab Laser, which has been designed for industrial use.

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 substrate material as shown diagrammatically in Figure 1..

Figure 1. CO₂ laser beam focused onto an absorbing surface Many other materials also absorb and will mark at the infrared CO₂ laser wavelength. These include glass (forms contrasting micro cracks at the surface), some plastics (contrast by chemical change or melting) and coated metals. Non absorbing materials, which do not mark with a CO₂ laser, include most metals which reflect the laser beam and some plastics such as polyethylene which largely transmit the laser radiation. If the laser beam is now deflected by varying amounts in two dimensions, the laser beam can mark lines or curves onto the target material. By introducing processor-controlled deflection and gating the laser beam on and off, characters can be marked on the material in a vector font style. A galvanometer control board sends varying X and Y co-ordinate deflection values to the vector scanning head via a digital interface. Inside the head, each X and Y deflection value is converted to a voltage. A galvanometer, (often abbreviated to 'galvo') converts a voltage into a proportional rotation of a shaft. A mirror is mounted to each shaft to deflect the laser beam. The galvanometers are mounted on perpendicular axes so that they control the deflection in the X and Y axis.

This is a Class 4 (Class IV) Laser and the beam is invisible to the eye. Please review all safety instructions and precautions given at the start of this manual before attempting to operate or service the system.

Figure 2 Galvo 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. A distortion of the square image field is inherently caused by the path of the beam in the head and by the objective 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 corrected values. The faster the marked material moves, the faster is the requirement for lines or curves. All markable materials require a certain minimum value of energy to produce a dot on the surface of the material. This is dependent not only on the laser energy per pulse but also on the spot size achieved by the focusing optical system and the actual material to be marked. The smaller the spot, the higher is the energy density on the material. Some materials require less energy density to mark than others eg. ink on a carton generally requires less energy density to mark than glass for instance. The system is normally installed on a production line or conveyor where products move past the system’s scanning head. Marking of items on the production line is normally initiated by a product detector, 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-the-fly' is achieved. Accurate measurement and compensation of the product movement is achieved by using a tachometer (shaft encoder) coupled to the System

System Layout

The system consists of a single main cabinet (1), an articulated arm (2), and a scanning head (3) as shown in Figure 3 The main cabinet contains the CO₂ laser tube, its power supplies, the air to water heat exchanging unit, the electronics control boards, the user interface control and the external interfaces for connection and integration to the production line. The articulated beam delivery contains mirrors that are utilised to direct the laser beam pulses into the scanning head. The user interface control panel area is located on top of the main system cabinet. This system is supplied with an integrated user interface controller, QWERTY keypad and VGA display The system has been specifically designed for very low maintenance operation and minimal user intervention or adjustment. The system has no initial warm-up time or recommended daily maintenance requirements. Once the system is correctly installed and programmed it can simply be turned on and off to initiate or finish coding.

Preliminary checks

• Ensure the power is connected via the mains socket on the rear panel of the system. • Check that the system’s remote interlock connection and the remote emergency stop circuit are made through the external interface. See the separate Installation manual (part no. 906-0149-00) if in doubt regarding the connections. • Check that the system can receive signals to mark from a triggering device such as a product detector connected to the external interface. Refer to the separate Installation manual (part no: 906-0149-00) if in doubt regarding the connections. • The ’System Status’ screen also displays warnings with a message.

System turn on

• Turn the Mains Isolator Switch on the rear panel of the system to the (on) position. At this stage, the system will initialise and the lamps will come on momentarily for a lamp test. Note that after initialisation, the last code printed is shown in the top part of the display on the ‘Print’ screen and the Standby and Laser Emission lamps will be illuminated. • Referring to Figure 5, insert the Shutter and Power Keys into the Shutter Key Switch and Power Key Switch respectively. Ensure both keys are in the 0 (off) and shutter closed positions. • Ensure that the Emergency Stop Button is released – slight rotation clockwise to release. • Turn the Power Key to the I (on) position. • Turn the Power Key to the momentary start position and release the key back to the I (on) position. This action turns on the DC power supply and enables the laser. The DC power supply will take approximately 15 seconds to energise. During this time, the system will not print and a warning message will be displayed “waiting for 48V supply”. • Turn the Shutter Key to the shutter open position. • The last code used will displayed in the top half of the display, press F10 to print the code. This action enables the system to print. • Products that interrupt the product detector should now be printed with the message shown in the top part of the user display.

Recommendations

• Printing While printing, changing to different screens (status / settings / edit etc) incurs additional software processing time which may in some instances momentarily interrupt the repetition of the print. It is therefore important to avoid changing screens where possible while printing.

Focus Adjustment

• Run a test product down the production line past the scanning head and examine the mark produced. Compare the new mark with the previous mark and ensure that the spot size and mark quality is comparable. • If the spot size is not similar then slight adjustment of the scanning head position may be necessary. First switch off the system and isolate from the mains supply and then loosen the scanning head clamping mechanism. • Now move the scanning head slightly forward by about 1 or 2mm and repeat instruction above. Note that only small movements should be necessary to achieve a perfect mark. • If the spot size increases then repeat the above procedure, but move the scanning head in the opposite direction by 1 or 2mm. It may take several small movements to achieve the best quality mark and spot size.

Optimising mark codes for 'on-the-fly' marking

When marking on-the-fly, the capability of the system to mark at a particular line speed depends on a number of factors. The laser marking parameters are optimised for the fastest marking, while maintaining an acceptable marking quality. The total time to mark a code is affected by the following parameters:- Mark speed / Jump speed / Mark delay / Jump delay / Polygon delay The following parameters do not affect the overall mark time, only the quality of the mark:- Off delay / On delay / Frequency / Duty The following factors should also be considered when determining the mark time: - • The number of characters • The size of the characters • The font – simple line fonts are marked in less time than bold two or three line fonts. • The jump distances between fields. Automatic or manual optimisation can be applied to a mark code. This allows the marking order, direction and position to be changed to achieve an optimised code for on-the-fly or static marking. Refer to the Software Manual for further details (906-0039-xx).

Switch Off Procedure

1 Press the Shut Down Button as shown below,

Then wait for the confirmation screen

• Turn the shutter key switch to the closed position. • Turn the power key switch to the 0 (off) position. • Turn the mains isolator switch on the rear of the system to the off position. Note that the power and shutter keys can only be removed in the off position. When the system is switched off, the keys should always be removed and kept in a secure location to prevent unauthorised use of the laser system. As an extra precaution, the isolator switch is designed so that it can be padlocked in the off position.

Manual Restart

It is a statutory requirement of 21 CFR 1040.10 that the laser output should not be restored automatically if the mains power fails or an interlock is broken and then reset. This is also a requirement of EN 60825-1:2014, where a remote interlock connection is being used as a safety interlock on an access panel of a protective enclosure that when removed, will change the class of the installed system to a Class 4 (Class IV) laser product. • Mains Power Failure In the event of a mains power failure, the laser and its power supply will be disabled and will not be restored when the mains power is re-established. In order to restart the laser system, turn the isolator switch to the off position and then repeat the System Turn On procedure given on page 19. • Remote Interlock Broken In the event that the remote interlock is broken, e.g. opening of the beam guarding door, the laser will be disabled. When the remote interlock is restored the series of events to re-enable the laser to print depends on the Interlock Mode chosen in the hardware/software. The default factory setting is Interlock Mode 1 and in this case the laser will not be re-enabled when the remote interlock connection is restored e.g. guarding door is closed. Mode 1 meets the safety requirements of CDRH and EN 60825-1:2014. In order to restart the laser after a remote interlock re-make: (Jumper configuration required on fuse board)

• Interlock Mode 0 1 Return the Shutter Key to the closed position. 2 Turn the Power Key to the momentary start position and release back to the I (on) position. This action turns on the DC power supply and enables the laser. The DC power supply will take approximately 15 seconds to energise. During this time, the system will not print and a warning message will be displayed - “Waiting for DC”. 3 Turn the Shutter Key to the open position. This action enables the system to print. • Interlock Mode 1 1 Press the Print button 2 Press 'Yes' to confirm laser activation • Interlock Mode 2 This is an automatic mode which means that the system will restart and the laser is enabled as soon as the interlock is remade.

Remote Keyboard (factory fitted option)

There are few differences between the standard system operation and the remote keyboard version. Assuming the keyboard is fully connected, when the main system AC power is turned on, the LCD screen should illuminate and a BIOS start-up screen will appear. Without pressing any keys the application software should be launched and appropriate menus displayed. This process takes approximately 3 minutes. In the remote keyboard version of the vector marking system, there are these additional features: - • The screen/keyboard/key-switches and monitor lamps are now located in a separate housing to be plugged into the main unit via a 5-metre umbilical. These items function as in the standard vector system. • The top plate of the laser assembly has a simplified layout containing 3 indicator lamps and an Emergency Stop switch. The lamps show the same pattern on both the main unit and the remote keyboard. • Either of the Emergency Stop switches may be used to stop the system printing. They do not stop the computer system. If the umbilical or keyboard is not present or not connected properly, the system cannot operate as the interlocks go through these items. • All 6 coloured indicators use LEDs and spares are provided. • Only the Emission Indicator devices are monitored for open circuit/short circuit faults. If either LED is removed or shorted, the system is capable of detecting and reporting this state while printing. • The LEDs on the main laser unit and the keyboard unit always agree.

It is the responsibility of the user to ensure that the Interlock Mode chosen fully conforms to local safety regulations governing use of the laser. For more information on safety please refer to the safety section at the start of this manual

Maintenance

General Information

The system range of systems, have been designed to be low maintenance marking lasers with low consumable costs. The only routine maintenance procedures which can be carried out are listed below. Check Frequency Comments Scan head Output Optic 1-3 Months Depends on environment, for cleaning procedure see page 24 Indicator Lamps Every 3 Months Bulb Part Numbers: 607-0023-00 (RED) 607-0024-00 (YELLOW) 607-0025-00 (GREEN) See page 26 Interlock Operation Every 6 Months See page 21 Liquid Coolant Every 6 Months Check levels are OK and there are no leaks. 18 Months Replace Coolant. This should only be carried out by a trained Engineer. The system's sealed construction and limited moving parts ensures trouble free and reliable operation with any internal faults being reported by the system’s software controlled monitoring system. Some external items will require periodic inspection and cleaning. These include the final optical element on the Scanning Head, the Compressed Air Supply, the Product Detectors and the Extraction System Filters. The frequency of inspection and cleaning will depend on how the system is integrated into the customer’s machine and more importantly, how well the final optic is protected from dust and contamination. Warning – Use of controls, 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 is invisible to the eye. Please review all safety instructions and precautions before attempting to operate or service the system. Always ensure that the laser system is switched off and isolated from the mains supply before attempting any cleaning or maintenance procedures.

Cleaning Optical Surfaces

The information contained in this section is intended to be used as a general guideline for cleaning optical grade materials. It is strongly recommended that a thorough understanding of this section be attained before any optic cleaning or handling procedures are attempted. Peak performance and efficiency of optical systems is only possible when the surfaces of the optical components are absolutely free of contamination. For example, a film of oily substance or specks of dust can substantially reduce the performance of the system. In most cases this will be seen as a gradual deterioration in the intensity of the beam on the target material ie. fading mark quality. Optical surfaces can be irreparably damaged by seemingly harmless debris or lint. Always switch off the laser system and isolate from the mains supply before proceeding with the cleaning of any optical surfaces on the system. This section is designed to introduce correct and safe methods for the cleaning of optical components. • Output Lens The only externally exposed optical surface on the system is the output lens on the Scanning Head. Depending on the orientation of the Scanning Head, the output lens may be more susceptable to dirt/debris (for instance if the scanner is pointing upwards). The recommended maintenance schedule should be adjusted accordingly. 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 and light scattering and in extreme cases this may permanently damage the optic and its coatings. If removed improperly, this debris can cause permanent damage. Remove any beam delivery or beam shroud and inspect the output optic. Clean if necessary, observing the methods described in this section. Leave the optic in its holder during the cleaning process. • Optics Cleaning Materials Lens tissue (first quality) Tissues (non-perfumed for rough work, wiping hands, etc). Disposable lint-free gloves. Solvents (highest purity, preferably anhydrous): Methanol, Ethanol, Isopropyl Alcohol (99.5% purity) Photographic blower brush • Cleaning Optical Surfaces Hands should be thoroughly washed to remove all oils, perspiration and grit. The hands should then be rinsed free of soap. Lint free gloves can be used for added protection of the optic. If there is visible dust, lint or other solid matter on the optics surface, gently blow it off with a photographic blower brush. Coated optics require careful handling, even the type labelled 'hard-coated'. If the surfaces are not badly contaminated, cleaning can be done fairly easily, a fresh sheet of lens tissues folded to form a pad

several layers thick. Its size will be a compromise between fully covering the diameter or width of the surface and being too large to clean evenly. Enough optical grade solution to just dampen the pad should be applied with a medicine type dropper. The pad should then be drawn across the surface in one smooth stroke, using very light pressure. The soiled pad must then be discarded. Repeat as necessary, using a clean pad for each stroke. Using new pads each time will minimise the possibility of scratching the optical coating. When the optic is clean, replace the optic and lens shroud and reconnect the compressed air. Where severe contamination has permanently damaged the optic, replace with a new component of the correct specification and in the correct orientation.

Compressed Air Supply

A compressed air supply is required where there is a possibility of contamination of the final lens which is normally 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 mark on the product to be coded. To prevent this contamination, a clean compressed air supply is recommended to provide slight positive pressure on the final lens shroud. The recommended specification is given in the Installation Manual. The recommended two stage air filtering will need regular inspection and maintenance where necessary and the period 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 lens is also contaminated – refer to page 23. Where filters are found to be clean, the period between inspections can be increased, it is recommended that the maximum time between inspections should be no more than one month.

Product Detectors

Always ensure that the laser system is switched off and isolated from the mains supply before attempting any cleaning of the product detectors. In general, product detectors can be occasionally wiped with a clean damp cloth to remove contamination from the active surfaces. Take care not to move or disturb the detectors during cleaning as this may affect code position on the product to be marked. Do not use abrasive materials as these may damage the detectors and render them inoperative. See the manufacturer’s instructions for more information on cleaning. The period between cleaning will depend on the environment of the production line. An initial daily inspection can be increased to a maximum of a weekly inspection where detectors are cleaned infrequently.

Extraction

An approved fume extraction unit should 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 the local Distributor and the manufacturer of the extraction equipment for any required change to the extraction filter specification.

The filters used in the extraction system must be regularly inspected, changed and disposed of in accordance with the manufacturer’s instructions. In broad terms, this will depend on the construction of the extraction system, the filter 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.

Replacing faulty Indicator Lamps

It may be necessary to replace the indicator bulbs on the user interface panel, if this is the case please follow the instructions below. • To check the operation of the indicator bulbs, whilst the system is in standby mode, activate the Emergency Stop button. All three indicator bulbs should now be lit. To replace any faulty bulbs, following instructions below. • Remove the coloured lens from the lamp holder to gain access to the faulty bulb. The bulb can then be removed using the bulb puller tool part number 553-0004-00, (shown here below Figure 6) which is provided in the spares kit supplied with the system.

PC System Battery Replacement

The internal PC in this system uses a CR2032 battery. If this battery needs to be replaced it should only be replaced with a battery of the same type, by trained personnel.

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 (see below). They must be fitted over the key switches before attempting any cleaning or wash-down procedures The external surfaces of the system can be cleaned with a mild detergent. It is advisable to use a damp cloth to facilitate the cleaning of the external cabinets, etc. Take care not to allow water into the system cabinet or the final optic beam shroud.
