Precautions
WARNING
1. Do not use the F3S-B on machines that can not be stopped by electrical control in case of an emergency.
2. Do not use the F3S-B in flammable or explosive environments.
3. Always maintain the safety distance between F3S-B and a hazardous part of the machine. Serious injury may result if the
machine does not stop before someone reaches the hazardous part.
4. Install protective structures around a machine so that you must pass through the detection zone to reach a hazardous part of
the machine.
5. Install F3S-B so that some parts of the operator’s body remain in the detection zone at all times when the operator works in that
hazardous area.
6. Failure to do so may result in serious injury.

J CORRECT I NSTALLATION
A hazardous part of a machine can be
reached only by passing through the sensor
detection zone.
Some part of the operator’s body remains in
the detection zone while they are w orking.
J INCORRECT INSTALLATION
A hazardous part of the machine can be
reached without passi ng through the sensor
detected zone.

WARNING
1. Be sure to i nstall the F3S-B to minimize the effects of reflections from reflective surfaces.
Failure to do so will create an inability to detect and may result in serious injury.
2. Install the F3S-B with a minimum distance D as shown below from the reflective surface (highly reflective surfaces)
like metal walls, floors, ceilings, and work pieces.
