F3SJ-A
User’s Manual
Checklists
Pre-Operation Checklists
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.
After installation, the highest level administrator must use the following checklist to verify the operation,
placing a check mark in each of the boxes.
Checklists
Installation condition check
The machine itself does not prevent the operation of safety functions such as stopping.
The hazardous part of a machine cannot be reached without passing through the detection zone of
the F3SJ.
The system is configured so that the F3SJ can always detect a worker who is working in the
hazardous area.
The interlock reset switch is installed in a location that provides a clear view of the entire hazardous
area and it cannot be activated from within the hazardous area.
Safety distance has been calculated. Calculated distance: S = ( )mm
The actual distance is equal to or greater than the calculated distance. Actual distance = ( )mm
Reflective surfaces are not installed in prohibited areas.
Wiring check before power is turned ON
The power supply unit has tolerance against the total rated current of connected devices including the
F3SJ.
The power supply unit is a 24 VDC unit that conforms to the EMC Directive, Low-voltage Directive,
and output holding specifications.
The power supply polarity is not connected in reverse.
Emitter/receiver cables are properly connected to the respective emitters/receivers.
Double insulation is used between I/O lines and the hazard potential (commercial power supplies,
etc.).
Outputs are not short-circuited to +24V line.
Loads are not connected to the +24V line.
All lines are not connected to commercial power source.
When 2 or more sets of F3SJ are used, series connection is made or mutual interference prevention
measures are taken.
Operation check while the machine is stopped
The test rod is not deformed.
The detection capability varies according to the model. Use a test rod with an appropriate diameter
for inspection.
When the power of the F3SJ is turned ON while nothing is in the detection zone, it must operate as
follows:
When auto reset is made: Power indicator and ON output indicator must turn ON within 2 seconds
(2.2 seconds in case of series connection).
When manual reset is made: Power indicator and OFF output indicator must turn ON within 2
seconds (2.2 seconds in case of series connection).
The sensor can detect a test rod wherever it is in the detection zone. In other words, when a test rod
is inserted into the detection zone, all 5 incident light level indicators turn OFF, and the OFF-state
indicator turns ON.
