Machines
Do not use this sensor for machines that cannot be stopped quickly 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 the F3SG-SR in PSDI mode (initiation of cyclic operation by a presence sensing device),
you must configure an appropriate circuit between the F3SG-SR and the machine. For details
about PSDI, refer to OSHA 1910.217, IEC 61496-1, and other relevant standards and
regulations.
Installation
Make sure Responsible Person tests the operation of the F3SG-SR and F39-SGIT-IL3 after
installation to verify that the F3SG-SR and F39-SGIT-IL3 operate 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-SR 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-SR 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-SR'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.
Install the pre-reset switch always in the hazardous zone and where it cannot be activated from
outside the hazardous zone.
The F3SG-SR cannot protect a person from an object flying from the hazardous zone. Install
protective cover(s) or fence(s).
Install a protective structure to cover the whole blanked zone in order to prevent personnel
approach to hazardous part of the machine through the blanked zone.
Detection capability gets larger when Fixed Blanking, Floating Blanking or Reduced Resolution
function is used. When these functions are used, the safety distance calculation must be based
on the increased detection capability for these functions. Otherwise, the machine may not stop
before a person reaches to the hazardous part, resulting in serious injury.
