E
Observe the precautions described below to prevent operation failure, malfunctions, or undesirable effects on
product performance.
Storage conditions and installation environment
• Do not install, use, or store the product in the following types of environments:
- Areas with a temperature or humidity out of the specified range
- Areas submerged in water or subject to rain water
• This is a class A product (for industrial environments). In residential areas it may cause radio
interference, in which case the Responsible Person may be required to take adequate measures to
reduce interference.
Wiring and installation
• Properly perform the wiring after confirming the signal names of all the terminals.
• Do not operate the control system until 3 s or more after turning ON the power of the F3SG-SR.
• When using a commercially available switching regulator power supply, make sure to ground the PE
terminal (protective earth terminal).
• Install the emitter and receiver to the same vertical direction.
• Use brackets of specified quantities and locations according to the dimensions. If the brackets
described above are not used, ratings and performance cannot be met.
• Do not install the F3SG-SR close to a device that generates high-frequency noise. Otherwise, take
sufficient blocking measures.
• Sharing the power supply with other devices may cause the F3SG-SR to be affected by noise or
voltage drop. It is recommended that the F3SG-SR use a power supply dedicated for safety
components, not shared with other devices.
• Do not change the scan code during normal operation. The F3SG-SR transitions to lockout.
• Do not apply load to the connectors.
• The operating range of the safety light curtain attached with the spatter protection cover is 10%
shorter than the rating. Install the product in consideration with the decrease of the operating range.
Cleaning
• Do not use thinner, benzene, or acetone for cleaning. They affect the product's resin parts and paint
on the housing.
• Use a soft cloth which is dry or wetted with clean water for cleaning. Do not use solvents.
Object detection
• The F3SG-SR cannot detect transparent and/or translucent objects.
Settings
• Do not operate the DIP Switch on the F39-SGIT-IL3 during normal operation of the F3SG-SR.
Otherwise, the F3SG-SR enters the LOCKOUT state.
• Do not operate the DIP Switch and Push Switch on the F39-SGIT-IL3 with tools that may damage the
product.
• Be sure that the F3SG-SR is in the SETTING state when making a change to the setting.
For more information on the SETTING state, refer to SETTING State under 2-2-1. Operating States of F3SG-SR and
