Omron F3SG-R User Manual page 8

For machines
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 full-rotation clutch. Otherwise, the machine may
not stop before a person reaches the hazardous part, resulting in serious injury.
To use F3SG-R in PSDI mode (initiation of cycle operations by a presence sensing device), you
must configure an appropriate circuit between F3SG-R and the machine.For details about PSDI,
refer to OSHA1910.217, IEC61496-1, and other relevant standards and regulations.
For installation
Make sure Responsible Person tests the operation of the F3SG-R after installation to verify that
the F3SG-R operates as intended. Make sure to stop the machine until the test is complete.
Unintended installation, wiring or function settings may cause a person to go undetected,
resulting in serious injury.
Make sure to install the F3SG-R at the safety distance from the hazardous part of the machine.
Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in
serious injury.
Install a protective structure so that the hazardous part of a machine can only be reached by
passing through the sensor's detection zone. If access to the hazardous part by reaching over
the detection zone of a vertically mounted F3SG-R cannot be excluded, the height of the
detection zone and the safety distance shall be determined in consideration of such a risk. 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 F3SG-R's detection zone, configure the system with restart interlock
function. Failure to do so may result in serious injury due to unexpected startup.
Install the 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.
The F3SG-R cannot protect a person from a projectile exiting the hazardous zone. Install
protective cover(s) or fence(s).
Install F3SG-R so that it is not affected by reflective surfaces. Failure to do so may hinder
detection, resulting in serious injury. For an installation distance from reflective surfaces, see 4-1-
3. Distance from Reflective Surfaces.
When using more than 1 set of F3SG-R in adjacent areas, the emitter of one F3SG-R may
interfere with the receiver of the other, causing the safety functions to stop working properly.
Install, configure and maintain them so that mutual interference does not occur.
Make sure that foreign material such as water, oil, or dust does not enter the F3SG-R or the
connector while the cap is removed.
