Quick Installation Manual
7. Pre-Operation Checklists / Maintenance Checklists
After wiring, mounting and beam alignment are done, check the operation of the F3SG-SR-K.
Pre-Operation Checklists
After installation, the highest level administrator must use the following checklist to verify the operation, plac

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
F3SG-SR-K.
The system is configured so that the F3SG-SR-K 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 the 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 the 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 the F3SG-SR-K by mistake.
When the 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 the Muting function is used, MUTING state can be checked from where a worker operates or adjust
the machine.
A muting sensor consists of two independent devices.
It is not used in flammable or explosive atmosphere.
- Wiring Check Before Power Is Turned ON
When the power supply unit is connected to multiple devices, the power supply unit must have tolerance
against total rated current of the 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 lines are wired with a proper polarity according to the wiring specifications of the PNP
or NPN setting.
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 VDC line.
When using PNP output, loads are not connected to +24 VDC line. When using NPN output, loads are
not connected to 0 VDC line.
All lines are not connected to commercial power source.
Model of emitter and receiver must be the same.
When two or more F3SG-SR-K systems are used, they are prevented from mutual interference with each
other.
Neither bracket must be loose.
Auxiliary output must not be used as safety output.
When using PNP output, +24 VDC line of the power supply must not be grounded. When using NPN
