Checklists
6-1. Pre-Operation Checklists
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 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.
6-1-1. Checklists
6-1-1-1. 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 F3SG-R.

The system is configured so that the F3SG-R can always detect a worker who is working in the
hazardous zone.
 The interlock reset switch is installed in a location that provides a clear view of the entire hazardous
zone and it cannot be activated from within the hazardous zone.
 The pre-reset switch is installed in a location inside the hazardous zone and where it cannot be
operated from outside the hazardous zone.
 Safety distance has been calculated. Calculated distance: S = ( )mm
 Safety distance has been calculated with larger object resolution when floating blanking or reduced
resolution function is used.
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 zones.
 Not installed in a retro-reflective configuration.
 When muting function is used, a muting sensor must be installed so that muting state should not occur
when a human body enters a detection zone of F3SG-R by mistake.
 When muting function is used, a muting sensor must be installed so that muting state should not occur
when a human body enters a hazardous zone of a machine.
 When muting function is used, muting state can be checked from where a worker operates or adjust
the machine.
 A muting sensor consists of 2 independent devices.
 It is not used in flammable or explosive atmosphere.
6-1-1-2. Wiring Check Before Power Is Turned ON
 Power supply unit must be dedicated to F3SG-R and other devices for electrical-detection protective
function of F3SG-R such as safety controller and muting sensor, and must not be connected to other
devices. It must have tolerance against total rated current of devices if it is connected to multiple
devices.
 The power supply unit is a 24 VDC unit that conforms to the EMC Directive, Low-voltage Directive,
and output holding time 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.).
 When using PNP output, the outputs are not short-circuited to +24 VDC line. When using NPN output,
the outputs are not short-circuited to 0 V line.
 When using PNP output, loads are not connected to +24 VDC line. When using NPN output, loads
are not connected to 0 V line.
 All lines are not connected to commercial power source.
 F3SG-R's power supply connector and series connection connector must not be attached upside
