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
Power supply unit must be dedicated to electro-sensitive protective equipment such as F3SJ-B and
safety controller, and must not be connected to other devices. It must have tolerance against total
rated current of devices if it is connected to multiple 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 +24 V line.
Loads are not connected to the +24 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 two or more sets of F3SJ-Bs are used in series connection, sensors other than the F3SJ-B-
01TS must not be connected.
A cap is mounted to a secondary sensor farthest from its power supply.
Neither connector nor bracket must be loose.
Auxiliary output must not be used as safety output.
Power supply's 0 V must be grounded.
Wiring must not be bent, cracked, nor damaged.
