Chapter 5 Troubleshooting
<Reference>
● Check the wiring.
● Check the power supply voltage and the power supply capacity.
5-1 Troubleshooting of Emitter
<All indicators are OFF>
Cause
Remedy
Power is not being supplied
Check that the power supply capacity is sufficient.
Connect the power supply correctly.
Supply voltage is out of the specified range.
Set the supply voltage correctly.
Connector is not connected securely.
Connect the connector securely.
<Fault indicator (yellow) lights up or blinks>
Cause
Remedy
[Lights up]
Setting data error of this de-
vice
Noise is out of the specified
range.
Check the noise status around this device.
Incase the handy controller (
SFB-HC
) (optional)
is applied, reset the function.
Internal error
Contact our office.
[Blinks 1 time]
System error between emitter
and receiver
Systems are different be-
tween emitter and receiver.
Set the same value to the numbers of emitter and
receiver and that of beam channel, and the shield
wires.
[Blinks 4 times]
Interlock setting error
Voltage level of Interlock set-
ting input wire (pale purple),
or emission halt input / reset
input wire (pink) is unstable.
Wire the Interlock setting input wire (pale purple)
and emission halt input / reset input wire (pink)
correctly.
Refer to “
2-5 Wiring
.”
[Blinks 5, 9 times]
Muting auxiliary output error
Muting auxiliary output wire
(red) short-circuits with other
I/O wires.
Refer to “
2-5 Wiring
.”
Current value should be within the specified mut
-
ing auxiliary output.
Excessive incoming current
flows in the muting auxiliary
output.
Output polarity setting wire
(shield) and muting auxiliary
output wire (red) are not cor-
rectly wired.
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output).
Wire the muting auxiliary output wire (red) correctly.
Refer to “
2-5 Wiring
.”
Output circuit error
Output circuit is damaged. Replace this device.
[Blinks 6 times]
Output polarity setting wire
(shield) 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.
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.
[Blinks 10 times or more]
Effect from noise / power
supply or failure of internal
circuit
Affected by noise / power
supply.
Internal circuit is broken
down.
Check the noise status around this device.
Check the wiring status, supply voltage, and
power supply capacity.
When the synchroni wire (orange) and
synchronization - wire (orange / black) is extend-
ed with a cable other than exclusive cable, use a
0.2mm
2
or more shielded twisted pair cable.
If this device still does not work, confirm number of
blinks of the error indicator and call to our local office.
