F3SG-SR/PG
User’s Manual
Checklists
7-1. Pre-Operation Checklists
Make sure Responsible Person tests the operation of the F3SG-SR/PG and F39-SGIT-IL3 after
installation to verify that the F3SG-SR/PG 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.
After installation, the highest level administrator must use the following checklist to verify the operation,
placing a check mark in each of the boxes.
7-1-1. Checklists
7-1-1-1. 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-SR/PG.
The system is configured so that the F3SG-SR/PG 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/PG 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.
7-1-1-2. 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.).
