  • Page 3: For Safe Use Of Laser Products

    For safe use of laser products ●FDA (Food and Drug Administration, U.S.DHHS) part 1040 “Performance standards for light-emitting products” has been established for the purpose of preventing users from suffering injuries by laser products. This product belongs to “Class 1 laser product” according to the degree of the hazard specified in the classification system of FDA Standards 21CFR 1040.10 and 1040.11.

  • Page 6: Cautions

    Doing so may cause malfunctions from inductive interference. ●LA-511 employs a line-bypass capacitor system to enhance electrical noise resistance. If there is any equipment near the sensor such as supersonic welding machine which produces a high frequency noise, and in addition, if sensor mounting framework is electrically conductive, an insulation is required between the sensor and the framework.

  • Page 7: Mounting

    Mounting ●Since laser beam has a directional property, special care must be taken to the direction of the sensor when mounting. [Detector] [Projector] (Note 1) The tightening torque should be 1.17N･m{12kgf･cm} or less. (Note 2) When mounting sensors using provided mounting brackets, secure firmly both sides of the sensors with a pair of brackets.

  • Page 9 ●Remote Interlock Input When the remote interlock input (pink lead) is connected to 0V, the laser beam is emitted (when it is either opened or connected to +V, the laser emission goes out). You can make use of this procedure as one of daily checks before starting operation or if you need to use a laser beam.

    <Beam Alignment> ●Temporarily set projector and detector in their required position with the projecting eye facing the detector. Make the following adjustments watching the beam alignment monitor on detector. [Action of the beam alignment monitor] ●Move detector in the direction indicated by the yellow illuminated arrowheads until the indication going out.

  • Page 12: Span Adjustment (Adjustment Of Analog Output Voltage)

    <Span Adjustment (adjustment of analog output voltage) > Green LED glows 1. Place sensors in all beam incoming state. On the monitor, the green LED glows and all yellow arrowheads remain extinguished. 2. Turn the span adjustor with the screwdriver provided to obtain +5V of analog output voltage.
