Diagnostic Functions
Self-test
A self-test is performed to check for errors when the power is turned
ON (within 2 seconds / within 2.2 seconds when series connected).
Also, the self-test is regularly performed (within the response time)
while operating.
Waveform of Control Outputs
When the F3SJ is receiving light, the control outputs cyclically turn
OFF as shown below to test the output circuit. When this OFF signal
is fed back, the output circuit is diagnosed as normal. If the output
signal does not include an OFF pulse signal, the receiver determines
that a failure has occurred with the output circuit or wiring, and enters
lockout state. (Refer to the following illustration.)
External Test
This function performs a test to ensure that the safety system stops
properly when the F3SJ is interrupted, by using an external signal to
forcibly stop emission.
To stop emission, apply 9 to 24 V for PNP output types or 0 to 1.5 V
for NPN output types to the test input line of the emitter. Apply the
voltage for a minimum of 4 x the safety output response time.
Lockout
If an error is found in the self-test, the sensor enters lockout state,
keeps the safety output in the OFF state, and indicates the error at the
same time.
Resetting Lockout
When a cause of lockout is removed, you can release the lockout by
using either of the following methods.
[For PNP output]
After manual reset, apply voltage of 9 to 24 V for 100 ms or longer to
the reset input line, and set it open or apply 0 to 1.5 V.
After auto reset, apply voltage of 0 to 1.5 V for 100 ms or longer to the
reset input line, and set it open or apply 9 to 24 V.
[For NPN output]
After manual reset, apply voltage of 0 to 1.5 V for 100 ms or longer to
the reset input line, and set it open or apply 9 to 24 V.
After auto reset, apply voltage of 9 to 24 V for 100 ms or longer to the
reset input line, and set it open or apply 0 to 1.5 V.

External Device Monitoring Function
This function detects malfunctions, such as welded contacts in
external relays (or contactors) that control the hazardous area of a
machine.
This function constantly monitors that a specified voltage is applied to
the receiver's external device monitoring input line, and enters lockout
state when an error occurs. The relay's operational delay can be up
to 300 ms without being evaluated as an error.
For example, if a specified voltage is not applied to the external device
monitoring line because the normally closed (NC) contact is not
closed within 300 ms after the control outputs turn from ON to OFF, it
is evaluated as an error and enters a lockout state.
To utilize this function properly, use safety relays and contactors that
have forcibly guided or mechanically linked contact structure.
Other Functions
Auxiliary Output (Non-safety output)
The auxiliary output is used to monitor the status of the F3SJ.
This output can be connected to a device such as a relay, indication
lamp, programmable controller, etc.
There are two auxiliary outputs: Auxiliary output 1 and auxiliary output 2.
The auxiliary output modes can be changed with a setting tool. See
the User's Manual for details on the modes that can be set.
Do not use the auxiliary output or external indicator output for safety
applications.
Failure of these outputs may prevent detection of people and result in
serious injury.
Note: 1. Auxiliary output 1 has a load current of 300 mA max., and
Toff: Response time of control output's ON to OFF, Ton: Response
* When auxiliary output 2 is set as a control output inversion signal,
the response delay for control output becomes Toff x 3 max.
Auxiliary output 1: Control output inversion signal
Auxiliary output 2: Turns ON when the point of 30,000 operating
time of control output's OFF to ON
2. The timing when auxiliary output 1 is set as a control output
