Output waveform of the OSSD outputs
The OSSD outputs will be OFF as shown in the following figure in
order to perform the OSSD circuit self-test when the light curtain is in
the ON-state.
The OSSD circuit diagnosis is correct when this OFF signal is fed
back. If the output signal does not contain an OFF signal, the receiver
determines that there is an output circuit or wiring failure and goes into
the lockout condition.
The number of OFF signals depends on the number of light curtains

In the same way, the OSSD outputs will be ON as shown in the
following figure, to perform the OSSD circuit self-test when the light
curtain is in the OFF-state. (See the chart below.)
Check the input response time of a machine connected to the
F3SN-A carefully to ensure the machine will not malfunction due to
the OFF signal.
