5-1 Troubleshooting of Emitter

Symptom
All indicators are off.
Fault indicator (yellow)
lights up.
Fault indicator (yellow)
blinks.
Emission halt / Emission
intensity control indicator
(orange) blinks. [Fault
indicator (yellow) is off]
All the beam-axis
alignment indicators
(red) light up in red
Operation indicator
remains lit in red (light is
not received). (Note 2)
Notes: 1) Vs is the same voltage as the voltage of the power supply to be used.
2) Since the color of the operation indicator changes according to the ON / OFF state of the control output
(OSSD 1, OSSD 2), the operation indicator is marked as OSSD on the sensor.
If the device does not work normally after checking the items above, please consult
Panasonic Industrial Devices SUNX.
The blinking cycle of the fault indicator is shown as follows. Check the frequency of the
lighting after passing approx. 2 seconds of the lighting off.

Cause
Power is not being supplied.
Power supply voltage is out of
the specified range.
Connector is not connected
securely.
Setting data of the sensor: error
[1 blink]
Beam channel No. error
[2 blinks]
Series connection error
[3 blinks]
Total unit No. / total beam
channel No. error
[5 or more blinks]
Effect from noise / power supply
or failure of internal circuit
Emission is in halt condition
Synchronization line wiring fault
Receiver not in operation
Light is received on
beam-axis which is set the fix
blanking function from the emitter.
The beam channels
emitter and the receiver are not
correctly aligned.

Check that the power supply capacity is sufficient.
Connect the power supply correctly.
Set the power supply voltage correctly.
Connect the connector securely.
Check the noise status around the sensor.
When using SF-HC (optional), reset the function.
Even if the error is not cleared, contact Panasonic
Industrial Devices SUNX.
Connect the end cap correctly.
Connect the cable for series connection correctly.
Set the number of series connection to 3 sets or
less.
Set the total number of beam channels for series
connection to 192 or less.
Check the noise status around the sensor.
Check the wiring status, power voltage, and power
source amount.
Even if the error is not cleared, contact Panasonic
Industrial Devices SUNX.
Connect the emission halt input to +9V to Vs.
(Note 1)
Wire the synchronization line correctly.
Check the receiver for abnormality.
