  • Page 3 (1) The F3S-B has not received the type approval provided by Article 44-2 of the Industrial Safety and Health Law of Japan. Therefore, it cannot be used in Japan as a safety device for pressing or shearing machines provided by article 42 of that law.
  • Page 4 Do not install the F3S-B in a location affected by wall reflections (see “2-1 Installation Conditions”). Do not short the output lines to the +24 V line. Doing so will cause the output to be always ON, creating a hazardous situation.
  • Page 5 When using cables with a connector other than the F39-JB series cable, make sure the connector is rated IP54 or higher. The F3S-B will start operating in two seconds after the power is turned ON. Make sure that no op- eration faults will occur in the control system during this time.

  • Page 8: Description

    This function keeps the F3S-B in the OFF-state after power ON and every interruption of the detection zone. To reset this condition, 17 VDC to Vs (nominal 24 VDC) must be applied to the Interlock selection input of the emitter for 15 to 2500 ms. Otherwise the OFF-state continues even if nothing interrupts the detection zone.

  • Page 9: Instability Output

    The state of the MPCEs can be checked with the Relay monitoring function. A voltage of 17 VDC to Vs has to be applied to the Relay monitoring input through the NC contacts of the MPCEs when the F3S-B control outputs are in the OFF-state (see “2-3-2 Wiring diagram”). To ensure this logic relation, the MPCEs must be safety approved types, with forcibly guided contacts.
