Pre-Operation Checklists
Make sure to test the operation of the F3SJ-B after installation to verify that the F3SJ-B 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.

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 F3SJ-B.
 The system is configured so that the F3SJ-B 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.
 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 reflective configuration.
 Not used in flammable or explosive atmosphere.
 Wiring check before power is turned ON

Sharing the power supply with other devices may cause the F3SJ-E/B to be affected by noise or
voltage drop. It is recommended that this safety component use a dedicated power supply but do not
share with other devices.

The power supply unit provides 24 VDC while complying with the EMC Directive, Low Voltage
Directive, output holding specification.
 The power supply polarity is not connected in reverse.
 Emitter/receiver cables are properly connected to the respective emitters/receivers.
 Double insulation is provided between input/output and hazardous voltage (commercial power
source, etc.).
 Outputs are not short-circuited to 0 V line.
 Loads are not connected to the 0 V line.
 All lines are not connected to commercial power source.
 Model of emitter and receiver must be the same.
 When two or more sets of F3SJ-Bs are used, they are series-connected or mutual interference
prevention measures are taken.
 When 2 or more sets of F3SJ-B are used in series connection, they must not be connected to a sensor
other than F3SJ-B-T.
 A cap is attached to the secondary sensor that is located farthest from the power supply.
 Neither connector nor bracket must be loose.
 Auxiliary output must not be used as safety output.
 Power supply's +24 V must be grounded.
 Wiring must not be bent, cracked, nor damaged.
