OMRON Safety Product F3SG-R Series F3SG-[]R[][][][][][][][] Safety Light Curtain Instruction Sheet (Safety Precautions) (ENG JPN)
Summary
The F3SG-R Safety Light Curtain is critical equipment for industrial automation, designed to detect hazards within dangerous machine zones and prevent serious injury by ensuring safe stopping operation. This manual provides essential technical guidance covering proper installation, electrical wiring best practices (including dedicated PNP/NPN setups), required protective structures, and operational maintenance. It serves as a comprehensive resource for qualified "Responsible Persons" responsible for integrating the system into high-risk manufacturing and processing environments while maintaining safety compliance.

Frequently Asked Questions
What types of objects can the F3SG-R fail to detect?
The F3SG-R cannot detect transparent and/or translucent objects.
What liquids should not be used for cleaning the device?
Do not use thinner, benzene, or acetone; these substances affect the product's resin parts and paint.
How must I wire a load to the PNP and NPN outputs?
For PNP, connect the load between the output and 0 V line. For NPN, connect it between the output and +24 VDC.
When is it safe to operate the control system after power-up?
Do not operate the control system until 2 seconds or more after turning ON the power.
