External Test Function; Self-Test Function - Omron F3SJ-A series User Manual

External Test Function

This function forcibly stops the emission using an external signal. It can be used to verify that the
safety system should stop properly when the 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 0.3s plus 4 times 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 a response time)
while operating.
The timing chart is the same as the one for the basic system. For details, see the following the page.
