*1. Reverse the polarity of the power supply when using in the NPN system. Select a PLC of
PNP or NPN type according to the system of your application.
*2. Open or connect the line to 24 VDC if Operating Range Selection is used in Long Mode.
*3. When connecting to the PLC, the output mode must be changed with the SD Manager 3
according to your application. Refer to Chapter 4 Setting with SD Manager 3 for more
information on setting the functions by the SD Manager 3.
*4. This is the case for a PELV circuit.
*5. Set the function with the SD Manager 3, restore the settings to the F3SG-SR, and perform
wiring according to the wiring diagram.
*6. This wiring example shows light emission stop when connected to 24 VDC with PNP
setting, and light emission stop when connected to 0 VDC with NPN setting. If TEST switch
is not needed, refer to
2-6. External Test .
