    2. General Description 2.1. System overview The MULTISCAN® HE 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 18: 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 19 The MULTISCAN® HE 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.

    Symbol Explanation Shutter key switch: shutter closed position Shutter key switch: shutter open position Laser emission indicator Maintenance fault indicator. This fault prevents the system from marking. System standby indicator (conforms to 417-IEC-5009a). When in standby mode, the system will not mark until the operation indicated on the control panel has been performed.

  • Page 31: 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. Turn the shutter key to the Shutter closed position.
