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.
Voltage level of interlock set-
ting input wire (pale purple),
or emission halt input / reset
input wire (pink) is unstable.
Muting lamp output wire (red)
short-circuits with 0V or +V.
Muting lamp output wire (red)
short-circuits with other I/O
wires.
Excessive incoming current
flows in the muting lamp out-
put.
Output polarity setting wire
(shield) and muting lamp
output wire (red) are not cor-
rectly wired.
Output circuit error
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 po-
sition (emitter for emitter, receiver for receivers).
Incase 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.
Contact our office.
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."
Wire the interlock setting input wire (pale purple)
and emission halt input / reset input wire (pink)
correctly.
Wire the muting lamp output wires (red) correctly.
Refer to "2-5 Wiring."
Current value should be within the specified mut-
ing lamp output.
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output).
Wire the muting lamp output wire (red) correctly.
Refer to "2-5 Wiring."
Output circuit is damaged. Replace this device.
