Omron F3SJ Series Original Instructions Manual page 7

For installation
An actual performance is different according to the state of the installation, the user environment,
and the application. Make sure to test the operation of the F3SJ after installation to verify that the
F3SJ operates as intended. Make sure to stop the machine until the test is complete. Unintended
function settings may cause a person to go undetected, resulting in serious injury.
Make sure to install the F3SJ at the safe distance from the hazardous part of the equipment.
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 a
person that passes 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 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.
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.
The F3SJ cannot protect a person from a projectile exiting the hazardous zone. Install protective
cover(s) or fence(s).
To prevent personnel approach to dangerous part of the machine through an zone disabled by
the fixed blanking function, you must install a protective structure to cover the whole disabled
zone. Failure to do so may cause failure of human body detection, resulting in a serious injury.
You must ensure that a test rod is detected for all detection zones except where fixed or floating
blanking function is used. Failure to do so may cause failure of human body detection, resulting
in a serious injury.
Detection capability gets larger when fixed/floating blanking function is used. You must use the
detection capability for fixed and floating blanking functions. Failure to do so may cause failure of
machine stop before reaching the machine's dangerous part, resulting in a serious injury.
You must ensure that the system works as you intended after configuring floating blanking.
Failure to do so may result in serious injury.
Warning zone output is non-safety output. You must not include it to calculation of safety
distance.Otherwise safety distance may be reduced, resulting in serious injury.
A warning zone CANNOT be used for safety applications. Always install your system so that a
detection zone should be passed before reaching a source of danger.
The muting and override functions disable the safety functions of the device. You must ensure
safety using other method when these functions are operating.
Install muting sensors so that they can distinguish between the object that is being allowed to
pass through the detection zone and a person. If the muting function is activated by the detection
of a person, it may result in serious injury.
