User’s Manual
Wiring/Installation
Installation Conditions
Detection Zone and Approach
Install a protective structure so that the hazardous part of a machine can only be reached by passing
through the sensor's detection zone. Install the sensors so that part of the person is always present in
the detection zone when working in a machine's hazardous zones.
If a person is able to step into the hazardous zone of a machine and remain behind the F3SJ's
detection zone, configure the system with an interlock function that prevents the machine from being
restarted. Failure to do so may result in serious injury.
Do not use this sensor for machines that cannot be stopped by electrical control. For example, do not
use it for a pressing machine that uses a full-rotation clutch. Otherwise, the machine may not stop
before a person reaches the hazardous part, resulting in serious injury.
To use the F3SJ in PSDI mode (Reinitiation of cyclic operation by the protective equipment), you must
configure an appropriate circuit between the F3SJ and the machine. For details about PSDI, refer to
OSHA1910.217, IEC61496-1, and other relevant standards and regulations.
Install the interlock reset switch in a location that provides a clear view of the entire hazardous zone
and where it cannot be activated from within the hazardous zone.
Do not use the F3SJ in environments where flammable or explosive gases are present. Doing so may
cause an explosion.
The F3SJ cannot protect a person from an object flying from a hazardous zone. Install protective cover(s) or
fence(s).
Make sure that the F3SJ is securely mounted and its cables and connectors are properly connected.
Correct installation
Incorrect installation
The hazardous zone of a machine can be reached
only by passing through the sensor's detection zone.
While working, a person is inside the sensor's
detection zone.
It is possible to reach the hazardous zone of a machine
without passing through the sensor's detection zone.
A person is between the sensor's detection zone
and the hazardous zone of a machine.
