Muting auxiliary output error

Cause
Error in settings.
Internal failure
The number of sensors in se-
ries connection exceeds the
specified limit.
The total number of beam
channels of the sensors in
series connection exceeds
the specified limit.
Incorrect emitter and receiver
connection when connected
in a series connection.
In a series connection, the
DIP switches 1 / 2 (synchro-
nization method) are not all
set to the same state.
End cap is not attached.
Cable for series connection is
disconnected.
Another error has generated.
The emitter system and re-
ceiver system do not match.
Output polarity setting / lock-
out release input wire (pale
blue) is broken or shorted to
another input / output wire.
Incorrect connection of out-
put polarity setting / lockout
release input wire (pale blue)
on receiver side of emitter /
receiver.
The voltage of the power sup-
plied to the device exceeds
the specified range.
Output is shorted to another
input / output wire.
Excessive rush current in the
muting auxiliary output.
Output circuit error.
Remedy
I f y o u u s e d t h e c o m m u n i c a t i o n m o d u l e
SF4D-TM1 (option) and Configurator Light Cur-
tain software, initialize the function.
Contact our office.
Limit the number of sensors in series connection
to 5 or less.
Limit the total number of beam channels to 256
or less.
Connect emitters to emitters and receivers to re-
ceivers using a series connection cable.
Set all DIP switches 1 / 2 (synchronization meth-
od) to the same state.
Make sure the end cap is installed correctly.
• Make sure the cable for series connection is
connected correctly.
• Replace the cable for series connection.
Check the operation of other sensors in series
connection.
Make sure the beam pitch, number of sensors
and number of beam channels of the emitter and
receiver match.
Connect the output polarity setting / lockout re-
lease input wires (pale blue) of the emitter and
receiver in the same way.
• Using PNP output: Connect to 0V (blue)
• Using NPN output: Connect to + V (brown)
<Using PNP output>
Connect the output polarity setting / lockout re-
lease input wire (pale blue) to 0V (blue).
<Using NPN output>
Connect the output polarity setting / lockout re-
lease input wire (pale blue) to + V (brown).
Make sure the power supply voltage conforms to
the specification.
Use the muting auxiliary output at a current from
250mA or less.
Output circuit damage.
Replace the device.
