    2. General Description 2.1. System overview The MULTISCAN® VS is a vector laser marking system comprising: • a Radio Frequency (RF) excited, diffusion cooled, CO industrial slab laser • a high-speed galvanometer scanning head • a computer-based controller to position the laser beam on the workpiece •...

  • Page 16: Typical Production Line Installation

    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.
  • Page 17 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 the laser manufacturer, Luxinar Ltd does not accept liability for any damage or injury howsoever caused or arising.

    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.

  • Page 20: Scanning Head

    2.7. Scanning head The scanning head directs the laser beam to follow a programmed path on the product to be marked. The beam is directed by high-speed galvanometer mirrors within the head and is focussed by a final focus lens mounted on the output face of the head. Figure 19 - Typical scanning head A range of scanning heads and final focus lenses is available to match the size of the marking field and the code geometry.

When in standby mode, the system will not mark until the operation indicated on the control panel has been performed.

  • Page 29: Shut-Down

    Important! Changing to different screens (status, settings, edit, etc.) incurs an additional processor load that may interrupt repetitive mark cycles. If possible, avoid changing screens during marking. 3.3. Shut-down Stop the flow of products past the detector(s). On the control panel, press F5 for Shutdown, then press Yes to confirm shutdown. Turn the shutter key to the Shutter closed position.

    Every 18 months This should be carried out by a Luxinar trained engineer. Other marking system components will also require periodic inspection and cleaning. These include the compressed air supply filter, the product detectors and the fume extractor filters. The maintenance interval for these components will depend on how they are integrated into the marking station.

    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.

  • Page 35: Frost Protection

    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 the extraction filter specification.

  • Page 36: Product Detectors

    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 the active surfaces.

  • Page 37: Installation

    If any damage to the packaging or change to the tilt or shock labels has occurred in transit, inform both Luxinar Ltd and the shipping company before taking any other action. Insurance company inspection of the damage may be necessary before proceeding with the unpacking of the equipment.

    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 details of available options. Important! It is essential that the products are accurately positioned at the marking position to prevent variations in mark quality.

  • Page 42: Static Marking

    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 the lens 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.
