Control unit Designation Appearance Model No. Description Slim type control unit SF-C13 (Note) For PNP/NPN equivalent output type safety light curtain. Compatible with Control Category 4. Use in a safe location. Unaligned beam axes can be seen at a glance The beam-axis alignment indicators are distributed on the safety light curtains in four sections. As the indicators of the sections whose beam channels are aligned light up in red, the user can easily verify which beam channel axes have become aligned. Once all beam channels have become aligned, the indicators light up in green. Mounting bracket enables easy beam-axis alignment The beam-axis alignment is easy since angle adjustment is possible with the enclosed rear mounting bracket. Rear mounting bracket Less operating errors from extraneous light interference A double-scanning method and retry processing are some unique new technology that help to avoid momentary interference from extraneous light coming from nearby equipment. A reduction in operating errors resulting from extraneous light interference can mean less frequent machinery stoppages and reduces the amount of time that a production line is not running. Mutual interference is reduced without the need for interference prevention lines No interference prevention lines are required between different items of equipment, so that safety light curtains can be installed with greater flexibility. Upper two indicators: ON Lower two indicators: OFF Indicator at bottommost blinks red The bottommost beam channel axis is correctly aligned When the upper half of all beam channel axes are aligned ( ) Blinking Even though beam channels are only partially aligned, the user can determine which beam channels are aligned Beam axes of two upper blocks are aligned / beam axes of two lower blocks are not aligned Note: Refer to SF-C10 series pages (p.663~) for SF-C13.

  • Do not utilize this safety light curtain in “PSDI Mode”, in which the safety light curtain is utilized as an activator for machinery.
  • To use this product in the U.S.A., refer to OSHA 1910. 212 and OSHA 1910. 217 for installation, and in Europe, refer to EN ISO 13855 as well. Observe your national and local requirements before installing this product.
  • This catalog is a guide to select a suitable product. Be sure to read the instruction manual prior to its use. This device has a flameproof structure and explosionproof performance that can only be ensured when the product meets all of the specified conditions and specifications. Failure to observe any of them will result in the loss of the explosionproof performance. Cautions for explosion-protection
  • Use flameproof electric appliances that are compatible with hazardous locations (locations where an explosive atmosphere of gas or vapor may exist).
  • Make sure that the power supply is off while wiring. Otherwise, electric shock may result.
  • Never modify or repair the product yourself. Failure to follow this instruction may result in an explosion or ignition.
  • Protect the cables, or external conductors, against possible external damage by passing them through a sufficiently strong metallic tube or by other means.
  • Ground the grounding terminal without fail. Failure to follow this instruction may result in an explosion or ignition.
  • Do not open the lid of the flameproof enclosure, and do not remove the window frame fixtures of the enclosure. Failure to follow this instruction may result in an explosion or ignition.
  • The product can be used in Zone 1 or Zone 2 areas where explosive gases may exist and flameproof appliances in groups IIA and IIB and temperature classifications of T1 to T6 can be used. Never install in locations which are classified as “0” (Zone 0).
  • For the classification of hazardous locations and flameproof electric appliances, see each country’s electric equipment construction work principles and other related laws and regulations.
  • If the wiring is expected to be subjected to electromagnetic or electrostatic induction from the general circuits, separately protect it with a metallic tube or duct. Grounding Safe location()() SF-C13 BSF4-AH80 Hazardous location Metallic duct, etc.
  • Install the product in a location where it is less likely to suffer mechanical damage. Mounting
  • When mounting the safety light curtain, secure it in place using four M10 bolts.
  • The cable lead-in port is threaded for wiring protective tube or conduit (NPT 1/2). Using a steel wire tube etc., if necessary, screw a tube into the port at least five complete threads.
  • After beam alignment, tighten the hexagon-socket- head bolts for adjusting mounting angle for fixing. The recommended tightening torque is 1.5 to 1.7 N·m. (The hexagon-socket-head bolts for adjusting mounting angle are on top and bottom surfaces of the emitter and receiver.) Grounding
  • Ground the external grounding terminal on the flameproof enclosure to keep the grounding resistance at or below 100 Ω.
  • For grounding, use an electric wire with equivalent or higher insulation performance to a 600 V polyvinyl- insulated electric wire, and of a thickness ensuring safe carrying of the expected maximum ground current. Others
  • This device has been developed / produced for industrial use only.
  • Use the device according to the specifications of this product. Failure to follow this instruction may result in electric shock, injuries, or damage to the product.
  • Unpack the product with the right side facing up. If you do not follow this instruction, you may get injured.
  • Do not touch any terminals when measuring the insulation resistance. Failure to follow this instruction may result in electric shock.
  • If there is something abnormal with the product, immediately turn OFF the product. Otherwise, electric shock, injuries, or a fire may result.
  • Before measuring the insulation resistance, confirm that there is no explosive atmosphere of gases or vapor around. Failure to follow this instruction may result in an explosion or ignition. Refer to p.1595 for general precautions.
