SF-C11

SF4B / SF4B-G series wiring diagram (Control Category 4)

For PNP output (minus ground)

• Set the safety light curtain input polarity selection switch to the PNP side and ground the 0 V line.

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.
2)	Use a momentary-type switch as the reset (RESET) button.
3)	Emission halt occurs when the test (TEST) button is open, and emission occurs when the test (TEST) button is short-circuited. If not using the test (TEST) button, short-circuit T1 and T2.

For NPN output (plus ground)

In the above diagram, set the safety light curtain input polarity selection switch to the NPN side and ground the + side.
