External Test Function; Self-Test Function - Omron F3SJ-A P Series User Manual

External Test Function

This function forcibly stops the emission using an external signal. It can be used to verify that a safety
system should properly stop when F3SJ is interrupted.
To stop the emission, apply 9 to 24V to the emitter's test input line. The voltage must be applied for a
period 4 times that of Toff or longer.

Self-Test Function

The F3SJ performs the self-test when power is turned ON (within 2 second, or 2.2 seconds in case of
series connection) to check for errors. Also, it regularly performs the self-test (within the response
time) while operating.

If an error is found in the self-test, the F3SJ enters lockout state, keeps the safety outputs in the OFF
state, and indicates the error at the same time.
