F3SG-SR
User’s Manual
Introduction
E
Do not use the F3SG-SR with mirrors in a retro-reflective configuration. Doing so may hinder
detection. It is possible to use mirrors to alter the detection zone to a 90-degree angle.
Wiring
When using the PNP output, connect the load between the output and 0 V line. When using the
NPN output, connect the load between the output and +24 VDC line. Connecting the load
between the output and a different power supply line from the above line will result in a
dangerous condition because the operation mode of safety outputs are reversed to "Dark-ON".
When using the PNP output, do not ground +24 VDC line. When using the NPN output, do not
ground 0 V line. Otherwise, a ground fault may turn the safety outputs ON, resulting in a failure of
stopping the machine.
Configure the system by using the optimal number of safety outputs that satisfy the requirements
of the necessary safety category.
Do not connect each line of the F3SG-SR to a DC power supply of higher than 24 VDC+20%.
Also, do not connect it to an AC power supply. Failure to do so may result in electric shock.
Make sure to perform wiring while the power supply is OFF.
Do not use the output signal of the auxiliary output or IO-Link output for safety applications.
Failure to do so may result in serious injury when the F3SG-SR fails.
