Waveform of Safety Outputs
When the F3SJ is receiving light, the safety 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 diagnoses a failure in the output circuit or
wiring, and it enters lockout state. (See the table below.)
