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.

[Digital error indicator: ]
Setting data error of this device
Series connection is in-
correct.
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.
Noise is out of the specified
range.
Check the noise status around this device.
In case the handy controller (
SFB-HC
) (optional)
is applied, reset the function.
Internal error
Contact our office.
[Digital error indicator: ]
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.
[Digital error indicator: ]
Series connection error
The serial signal short-circuits
or comes down.
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.
Any of the main / sub sensor
is in error.
[Digital error indicator: ]
No. of total units / No. of total
beam channels error
No. of total units / No. of total
beam channels is out of the
specified range.
Set the condition of the series connection within
the specification.
Refer to “
2-5-6 Series Connection
.”

Digital error indicator: ]
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.
[Digital error indicator: , ]
Muting lamp error
Muting lamp output wire (red)
short-circuits with 0V or +V.
Wire the muting lamp output wires (red) correctly.
Refer to “
2-5 Wiring
.”
Current value should be within the specified mut
-
ing lamp output.
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.
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 error
Output circuit is damaged. Replace this device.
