    1. LASER SAFETY 1.1. LASER TYPES There are different types of lasers according to the medium of photon propagation (gas, solid, liquid, etc.) contained inside the laser tube and the excitation mechanism used to cause the laser process. As a result, laser emissions of different wavelengths (energy content and power) are obtained.
  • Page 7 (2) The area where the laser marking system will be operating must be identified with a suitable warning sign (supplied by HITACHI) (3) The beam and incidence area must be surrounded by the material resistant to the wavelength emitted by the laser in order to avoid specular reflection in the invisible spectrum due to the far infrared laser emission.

    EMISSION SAFETY OF LASER PRODUCTS, EQUIPMENT CLASSIFICATION, REQUIREMENTS AND USER’S GUIDE. Safety devices and protections supplied by HITACHI will not necessarily meet requirements of the Customer’s Local Factory Inspector, Laser Safety and Country Regulations and no warranty or representation is given or made that they comply with any statutory or other requirement. No liability is accepted by HITACHI in this respect.

  • Page 9: Protective Casing

    1.2.2. PROTECTIVE CASING The area between the marking head and the printing surface must have the protective casing to prevent user access to the laser marking system. Making this protective casing is the responsibility of the installer in each country. Example of a protective casing: The steps required to create a protective casing are shown below.
  • Page 10 (7) Using a jig saw, make an opening where the focus lens will be inserted. (8) Polish the edges of the opening. In order to have access to the marking area, a hinge should be mounted between this cover and the rear cover.

    Goggles protect against scattered radiation or reflections from metal surfaces. Protective goggles that block 10.6µm CO2 laser radiation are available from HITACHI. RADIATION VIEWING CONDITIONS The laser exiting the resonator is considered an intense monochromatic light source. Due to these features it can be seen as a source of high luminosity.
  • Page 12 This is the most frequent viewing condition during laser system operation. Viewing the beam up close is dangerous, but appropriate filters and goggles can ensure safety, even during prolonged exposure. The Optical Risk Nominal Distance (O.R.N.D.) for laser systems of HITACHI can be over 20m for direct or reflected radiation, and over 1m for Dispersive radiation.

  • Page 13: Possible Personal Injury

    Materials processing can generate air contaminants such as vapours, fumes, and/or particles that may be noxious, toxic, or even fatal. Material Safety Data Sheets (MSDS) for materials being processed should be thoroughly evaluated and the adequacy of provisions for fume extraction, filtering and venting should be carefully considered.

  • Page 14: Compliance With Regulation And Law

    1.4.1. CDRH REQUIREMENTS HITACHI laser marking system is designed to comply with requirements for Class IV laser products imposed by the Radiation Control for Health and Safety Act of 1968. Under this act, the U.S Food and Drug Administration (FDA) issued a performance standard in the Code of Federal Regulations (CFR) for laser products.

  • Page 15: United States Federal Communications Comission Requirements

    Safe operation of the laser requires the use of external beam block to safely block the beam from travelling beyond the desired work area. Use a firebrick or similar non-dispersive, non-combustible material as the block. NEVER use organic material or metals as the beam blocker. Organic material, in general, are combustible and metals act as reflectors that may create an area of immediate danger.

    Directive does not apply to this system. Concerning the incorporation of the laser marking system into equipment that may fall under the definition of Machinery, HITACHI considers the application of the EMC Directive and Low voltage directive as sufficient evidence that the laser marking system will not compromise the compliance of the Machinery into which it is incorporated.
  • Page 17 Supplementary devices include RC units to mount parallel to AC relay coils, diodes to mount parallel to DC relay coils, filters for high frequency conducted disturbance to be mounted on the network input (ask Hitachi for the most suitable type). •COMPLIANCE WITH REGULATION AND LAW 1-12...
  • Page 18 The emergency function is the installer’s responsibility. (5) Protection category. Most HITACHI Laser System have a minimum protection category of IP20. To comply with the Machine Directive and Standard EN 60204, the installer is responsible for placing them in a suitable container according to the protection category required for the end use.
  • Page 19 In terms of operating safety, the ground connection helps prevent the occurrence of dangerous voltage between parts that are accessible at the same time, up to frequencies for which the ground connection (solely designed for the safety of individuals) can be considered low impedance. Therefore, at high frequencies (over a few tens of MHz) the impedance of the ground connection is completely unpredictable, and there is no guarantee of protection at high frequencies.

    13.3. CLEANING THE LASER SYSTEM 13.3.1. ASPECTS TO CONSIDER The most contaminating element for the lenses is dust or the vaporized material itself. These elements can be removed with a small air pump. It is not recommended to use any type of aerosol because it could lead to freezing if it is not kept completely vertical and at a prudent distance.

  • Page 56: Mirrors And Lenses

    13.3.4. MIRRORS AND LENSES Pay special attention when handling the lens holder to ensure the lens surface is not touched by fingers or any other object. Clean all lenses with acetone and optical paper. During the marking process a volatilization of particles and fumes occurs on the surface of the product being marked, which are absorbed by the extractor system.

  • Page 57: Lens Cleaning

    13.3.5. LENS CLEANING Lens cleaning must be done using latex gloves. Carry out the following steps to clean the lens: 1. Make sure the laser is not enabled. (In any case, it is advisable to turn the system off to clean the lens).

  • Page 58: Replacement Of Air Filters

    13.4. REPLACEMENT OF AIR FILTERS LM-C300 S/P includes one air filter on the top of the laser system. They must be replaced periodically with new filters (once a year). Only elements supplied by HITACHI or its distributors must be used.
