11. Troubleshooting
● Troubleshooting of emitter
<All indicators are OFF>
Cause
Power is not being supplied.
Supply voltage is out of the specified range. Set the supply voltage correc ly.
Connector is not connected securely.
<Fault indicator (yellow) lights up or blinks>
Cause
[Digital error indicator: ]
Setting data error of this device
Series connection is in-correct.
Noise is out of the specified range.
Internal error
[Digital error indicator: ]
System error between emitter and receiver
Systems are different between emitter
and receiver.
[Digital error indicator: ]
Series connection error
The serial signal short-circuits or comes
down.
Any of the main / sub sensor is in error.
[Digital error indicator: ]
No. of total units / No. of total beam chan-
nels error
No. of total units / No. of total beam
channels is out of the specified range.
[Digital error indicator: ]
Interlock setting error
Voltage level of interlock setting input
wire (pale purple) or emission halt input
/ reset input wire (pink) is unstable.
[Digital error indicator: , ]
Muting lamp error
Muting lamp output wire (red) short-
circuits with 0V or +V.
Muting lamp output short-circuits with
other I/O wires.
Excessive incoming cur-rent flows in the
muting lamp output.
Output polarity setting wire (shield) and
muting lamp output wire (red) are not
correctly wired.
Output circuit error.
[Digital error indicator: ]
Wiring error of the output polarity setting
wire (shield)
Output polarity setting wire (shield) comes
down or short-circuits with other I/O wires.
Output polarity setting wire (shield) con-
nection of emitter / receiver is incorrect.

Check that the power supply capacity is sufficient. Connect the
power supply correctly.
Connect the connector securely.
Check that the cable for series connection does not short-circuit, or is con-
nected to the correct position (emitter for emitter, receiver for receivers).
Incase the handy controller SE9Z-HC (optional) is applied, reset the function.
Check the noise status around this device.
If the handy controller SE9Z-HC (optional) is used, reset the function.
Contact our office.
Set the same value to the number of beam channels of emitter and
receiver and the output polarity setting wire (shield).
Check if the end cap has been fitted properly.
Check that the cable for series connection does not short-circuit, or is con-
nected 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 condi ion of the series connection wi hin the specification.
Wire the interlock set ing input wire (pale purple) and emission halt
input / reset input wire (pink) correctly.
Wire the muting lamp output wire (red) correctly.
Current value should be wi hin the specified muting lamp output.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the muting lamp output wire (red) to +V.
Output circuit is damaged. Replace this device.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of the receiver correctly.
