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 = (
 Safety distance has been calculated with larger object resolution when the Floating Blanking or
Reduced Resolution function is used.
Calculated distance: S = (
 The actual distance is equal to or greater than the calculated distance. Actual distance = (
 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.).
