SF4B-□C wiring diagrams (Control Category 4)

For PNP output (minus ground)

  • Connect the safety light curtain control outputs OSSD 1 and OSSD 2 to S1 and S2 respectively.
For PNP output (minus ground)
KA, KB: External device
(Forced guided relay or magnetic contactor)
Notes: 1) The above diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.
Notes: 2) Use a momentary-type switch as the reset (RESET) button.

For NPN output (plus ground)

  • Connect the safety light curtain control outputs OSSD 1 and OSSD 2 to S4 and S2 respectively and ground the + side.
For NPN output (plus ground)
KA, KB: External device
(Forced guided relay or magnetic contactor)
Notes: 1) The above diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.
Notes: 2) Use a momentary-type switch as the reset (RESET) button.

Wiring diagram: SF-C13 control unit

For PNP output (minus to ground)

  • Connect the control output 1 (OSSD1) to S1 and the control output 2 (OSSD2) to S2.
For PNP output
Notes:
1) The above design is when using manual reset. If automatic reset is used, disconnect the lead wire from X2 and connect it to X3.
In this case, a reset (RESET) button is not needed.
2) Use a momentary-type switch as the reset (RESET) button.
3) Unused wires must be insulated.

For NPN output (plus to ground)

  • Connect the control output 1 (OSSD1) to S4 and the control output 2 (OSSD2) to S2.
For NPN output
Notes:
1) The above design is when using manual reset. If automatic reset is used, disconnect the lead wire from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.
2) Use a momentary-type switch as the reset (RESET) button.
3) Unused wires must be insulated.
