Pre-Operation Checklists

Make sure to test the operation of the F3SJ-E/B after installation to verify that the F3SJ-E/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-E/B.
 The system is configured so that the F3SJ-E/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 = (
 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 reflective configuration.
 When 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 F3SJ-E/B by mistake.
 When 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 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.
 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-E/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, a PNP type must not be connected
to an NPN type, and vice versa.
A secondary sensor farthest from its power supply has either of the following:
•Cap
•Key cap for muting
Neither connector nor bracket must be loose.
Auxiliary output must not be used as safety output.
