<Output waveform [control output (OSSD 1 / 2) ON]>
Since the receiver performs the self-diagnosis of the output circuit when the device is in light receiving
status (ON status), the output transistor becomes OFF status periodically. (Refer to the figure below.)
When the OFF signal is fed back, the receiver judges the output circuit as normal. When the
OFF signal is not fed back, the receiver judges either the output circuit or wiring as error, and
the control output (OSSD 1 / 2) maintains OFF status.

● In case the muting lamp is used, a total length should be 40m or less (for each
emitter / receiver).
● When the synchronization + wire (orange) and synchronization - wire (orange
/ black) is extended with a cable other than exclusive cable, use a 0.2mm
more shielded twisted pair cable.
