5. After 3 seconds of power input, use a machine or mechanical system. Failure to follow this instruction may cause malfunction or danger due to the safety- related function that does not operate properly.
6. Responsible person for use is an operator who: – is fully knowledgeable about the installation, settings, use and maintenance of the product. – is familiar with the requirements of laws, regulations and standards in the country or region where the product is installed and used. Responsible person for use has an obligation to educate the requirements to machine users. Machine users are persons who have been fully trained by the responsible person for use and can operate the machine correctly. When any error occurs during the operation of the machine control system, they have a responsibility to report it to the responsible person for use immediately. If an unqualified person operates the product, it may result in personal injury, economic loss or fire.
7. Qualified personnel shall carry out installation, configuration and combination with the machine control system. If an unqualified person carries out installation, configuration and combination with the machine control system, it may cause malfunction or result in accidents due to undetected human body.
8. Make sure that only the responsible person uses the keys or tools for accessing and setting the light curtains. Failure to follow this instruction may cause malfunction or result in accidents.
9. SFL□-□-A models acquire KCs certification as an industrial robot protection device. Do not use it for any other purposes.
10. When the machine is not operating after installation, check that functions and settings of the product operate correctly as you intended. Failure to follow this instruction may result in personal injury due to undetected human body.
11. Always make sure that the safety distance between the light curtain and the hazardous part (hazardous zone or hazardous source) of the machine.

Cautions for Installation

For more information, refer to the “SFL/SFLA User Manual.”

• Install the unit correctly with the usage environment, location, and the designated specifications. Install the light curtain that complies with the following details.

  • Part(s) of the human body passes through the detection zone to the hazards of the machine.
  • Install an additional guard if part(s) of the human body access to hazards of the machine without passing through the detection zone.
  • If an operator works in the hazardous part of the machine, be sure to install the light curtain to detect part(s) of the human body.

• You must set the safety distance of the light curtain.
  Failure to this instruction, the machine cannot be stopped before reaching the hazardous part, and it may result in personal injury.
  The safety distance calculation may differ from laws, regulations, and standards. Therefore, be sure to use the appropriate formula which abides by the rules of the country.

• Install the emitter and the receiver face to each other and adjust the top and bottom beam of the light curtain to meet the centerline. Also, the switch settings of the emitter and the receiver must be the same.

• Be sure to apply the power to both the emitter and the receiver at the same time.
  If not, the product enters the lockout condition, and the red and green LED of the upper OSSD indicators flash alternately.

• Use a bracket suitable for the mounting method.
  The type and number of brackets differ depending on the length of the light curtain.

Cautions during Use

• Follow instructions in “Cautions during Use”. Otherwise, it may cause unexpected accidents.

• The power input of 24VDC   model is insulated and limited voltage/current or supply via power supply with SELV and Class 2.

• When supplying power with SMPS, ground the F.G. terminal and connect the noise suppression capacitor between 0V and F.G. terminal.

• Be sure to use separate F.G. between the product and equipment with a strong noise (welding machine). The same F.G. may result in malfunction.

• When installing the light curtain, make sure that the bottom indicators of the emitter and receiver are aligned exactly.

• Install the light curtain in a place where the emitter and receiver are not affected by walls or reflecting surfaces.

• If you use the light curtain as several sets, arrange them not to interfere with each other, or install with a shading plate.

• Do not install the light curtain in place where it is exposed to intense disturbance light (such as direct sunlight, sunlight, spotlights fluorescent lights, and etc.) or reflected light from glossary surface is directly incident on the receiver. If it is difficult to install in such a place, take additional safety measures using shading plates, hoods, etc.
  Failure to follow this instruction may cause malfunction or dangerous due to the safety related function do not operate properly.

• Make sure that any unused wires, when installing the product, should be insulated.

• Make sure that removable parts (including packing, end caps, product wires, covers, etc.)
  are properly assembled. Also, tighten the screws with specified tightening torque. Failure to follow this instruction may cause product degradation.

• Assessment of conformity to the required safety level is evaluated for the entire system.
  Please consult with a certified certification body regarding the assessment procedure.
