T1: Minimum pressing time of reset switch. Configurable from 100 to 500 ms in 100-ms increments by SD Manager 3.
T2: Minimum break time (300 ms)
T3: Minimum unblocked time during the time from removing to feeding parts. T3 = T1
T4: Minimum break time (300 ms)
T5: Minimum pressing time of press position switch. T5 = T1
T6: Wait time until double break is complete (30 s or less)
* When the machine is stopped by unintended block in the middle of pressing of parts, operation of the reset switch (S1) and then double dummy
break are needed for reinitiation of the machine cycle.
When a functional earth is necessary, wire an earth cable according to the example in 6-2-1-1. Auto Reset Mode with
Optical Synchronization and EDM Unused. Also refer to 5-4-4. Functional Earth Connection for more information.

DIP switch
Short : Connect the OPERATING RANGE SELECT INPUT line of the emitter to 0 VDC.
N/A
Perform wiring according to the wiring diagram.
N/A
Connect the TEST line of the emitter to 24V/0V of the emitter via a test switch (NO contact). *6
N/A
Do not connect the COM(+) and COM(-) lines of the of emitter and receiver with each other.
*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.
