Wiring · Connecting Procedure And Connector Pin Arrangement - Panasonic SF4B-F31G(V2) Instruction Manual

<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.

2-5-3 Wiring · Connecting Procedure and Connector Pin Arrangement
Connect the mating cable (with connector on one end or connector on both ends) to the con-
nector of the bottom cap cable which is mounted on this device (emitter and receiver).
Wire the other side of the mating cable according to the customer's application referring to the
connector pin arrangement given below.

Perform the wiring with paying attention to the input response time of the machine to be
connected to this device, since the OFF signal of this device might cause malfunction.

● When extending the cable, use the exclusive cable up to the total length of 50m (for
each emitter / receiver). Extending the cable longer than 50m may cause malfunc-
tion, which can result in death or serious injury. Besides, if two sets of the devices are
connected in series, up to total length of 30m (for each emitter / receiver) is allowed
for use, and if three sets of the devices are connected, up to total length of 20m (for
each emitter / receiver) is allowed for use. Extending the cable longer than the length
specified may cause malfunction, which can result in death or serious injury.
● 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.
