Checklists
7-1. Pre-Operation Checklists
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.
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.

The system is configured so that the F3SG-SR 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 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.).
