Safety Precautions
Refer to Warranty and Limitations of Liability.
Do not apply the F3W-D as safety mechanisms used
in pressing machines or any other safety
mechanisms for protecting the human body from
danger.
(1) Do not apply the F3W-D as safety mechanisms used in pressing
machines, shears, rolling machines, spinning machines, cotton
mill machines, or robots for the protection of an operator’s hands
and body.
(2) The F3W-D is designed for detection of the human body or moving
objects in the detection area but not for protection against danger.
(3) The F3W-D or any product incorporating the F3W-D may be
exported to any country. Should the F3W-D cause any problem
conflicting with local laws or related to product liability locally,
however, OMRON shall, without exception, assume no
responsibility for it.
● Operating Environment
• Do not use the Sensor in an environment containing flammable or
vol
atile gases.
• Do not use the Sensor underwater.
• Do not disassemble, repair, or modify the Sensor.
• Always turn OFF the system power before installing or replacing the
Sensor.
• Applying excessive force to the mode switch may result in damage.
Do not apply a force of more than 5 N.
Do not use the product in atmospheres or environments that exceed
product ratings.
● System Design
Mutual Interference Prevention Function
When using more than one set of the Sensors, install and configure
them so that no Mutual Interference occur.
(1) Two Sets of Sensors:
Set these Sensors to different frequencies with the frequency
selector. Refer to DIP Switch 1 Mode Switching on page 6.
If the mutual interference prevention function is not used, and there
are two Sensors with the same frequency setting, a beam from the
Emitter of one Sensor may hit the Receiver of the other Sensor,
resulting in malfunction.
This function cannot prevent mutual interference between the F3W-D
Sensor and a Photoelectric Sensor of a different model.
(2) Three or More Sets of Sensors:
When 3 or more sets of Sensors are used in parallel, mutual
interference may result in malfunction. Take the following measures
to prevent mutual interference, and check for mutual interference.
While in LONG mode, the Sensors are more easily affected by
interference. Therefore, if the distance between the Emitter and
Receiver of a Sensor is 1 m or less, use the SHORT mode.
