Section 3 I/O Circuit
B-25
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.

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.
Check the input response time of a machine connected to the F3SN-B carefully to ensure the machine will
not malfunction due to the OFF signal.
