Cause
Cause
S e r i e s c o n n e c t i o n i s i n -
correct.
Noise is out of the specified
range.
Internal error
Systems are different be-
tween emitter and receiver.
The serial signal short-circuits
or comes down.
Any of the main / sub sensor
is in error.
No. of total units / No. of total
beam channels is out of the
specified range.
Extraneous light is entering
or light from other model is
entering.
Control output 1 (OSSD 1)
wire (black) and control out-
put 2 (OSSD 2) wire (white)
short-circuits with 0V or +V.
Control output 1 (OSSD 1)
wire (black) or control output
2 (OSSD 2) wire (white) short-
circuit respectively, or short-
circuits with other I/O wires.
Excessive incoming current
flows in the Control output 1
(OSSD 1) wire (black) and
control output 2 (OSSD 2)
wire (white).
Output polarity setting wire
(shield) and control output 1
(OSSD 1) wire (black) and
control output 2 (OSSD 2) wire
(white) are not correctly wired.
Output circuit error
Output polarity setting wire
(shield) comes down or short-
circuits with other I/O wires.
Output polarity setting wire
(shield) connection of emitter
/ receiver is incorrect.
Check that the power supply capacity is sufficient.
Connect the power supply correctly.
Set the supply voltage correctly.
Connect the connector securely.
Check that the cable for series connection does
not short-circuit, or is connected to the correct
position (emitter for emitter, receiver for receiver).
In case the handy controller (SFB-HC) (optional)
is applied, reset the function.
Check the noise status around this device.
In case the handy controller (SFB-HC) (optional)
is applied, reset the function.
Replace this device.
Set the same value to the numbers of emitter and
receiver and that of beam channel, and the shield
wires.
Check if the end cap has been fitted properly.
Check that the cable for series connection does
not short-circuit, or is connected to the correct
position (emitter for emitter, receiver for receiver).
Check the error contents of the device connected
by the cable for series connection.
Set the condition of the series connection within
the specification.
Refer to "2-5-6 Series Connection."
When the power is ON, prevent any extraneous
light from entering the receiver.
If the extraneous light is coming from this device,
conduct "2-3-4 Device Placement" or "3-4 Inter-
ference Prevention Function."
Wire the control output 1 (OSSD 1) wire (black) or
control output 2 (OSSD 2) wire (white) correctly.
Refer to "2-5 Wiring."
Current value should be within the specified
control output 1 (OSSD 1) wire (black) or control
output 2 (OSSD 2) wire (white).
Refer to "6-1 Specifications."
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output)
Wire the control output 1 (OSSD 1) wire (black) or
control output 2 (OSSD 2) wire (white) correctly.
Refer to "2-5 Wiring."
Output circuit is damaged. Replace this device.
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of
the receiver correctly.
