Precautions For Correct Use - Omron F3SG-SRB Series User Manual

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
