System Configuration and Functions

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 0 to 1.5V to the emitter's test input line. The voltage must be applied for a
period 0.3s plus 4 times of Toff or longer.
Response time p.17
 Operation of the F3SJ's Internal Indicators When External Test Function Is Performed
Blanking/test indicator blinks when voltage is applied to the test input.

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.
