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 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.
 Safety distance has been calculated. 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.
 It is not used in flammable or explosive atmosphere.
6-1-1-2. 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 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.).
 The outputs are not short-circuited to +24 VDC line.
 No loads are connected to +24 VDC 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
down.
 Model of emitter and receiver must be the same.
 When 2 or more F3SG-R systems are used, they are in cascade connection or prevented from mutual
interference with each other.
 On a secondary sensor farthest from its power supply, either of the following is attached:
- End Cap
- Lamp (F39-LP and F39-BTLP, sold separately)
- Bluetooth
® Communication Unit (F39-BT, sold separately)
 Neither connector, cap, or bracket must be loose.
 Auxiliary output must not be used as safety output.
 +24 VDC line of the power supply must not be grounded.
 Wiring must not be bent, cracked, nor damaged.
