Error indication
In case of error, attempt the following measures.
Error
indication
Description
Solution
Hold OFF
- - - -
Hold ON
Measured
value blinks
Insufficient amount of
reflected light.
The sensing object
is out of the sensing
range.
Confirm that the sensing distance is within
the specification range.
Adjust the installation angle of the sensor.
Flash memory is dam-
aged or passed its life
expectancy.
Please contact our office.
Load of the sensing
output is short-
circuited causing an
over-current to flow.
Turn OFF the power and check the load.
The semiconductor
laser is damaged or
passed its life expec-
tancy.
Please contact our office.
When zero set is set,
the measurement
is not performed
normally.
Since the display set-
ting is set to “Offset”,
the zero set function
can not be used.
Confirm that the sensing distance is within
the specification range.
Set the display to any setting except
“Offset.
During teaching, the
measurement is not
performed normally.
Confirm that the sensing distance is within
the specification range.
System error
Please contact our office.

Cautions
●
This product has been developed / produced for industrial use only.
●
Make sure that the power supply is OFF before starting the wiring.
●
If the wiring is performed incorrectly, it will cause a failure.
●
Do not run the wires together with high-voltage lines or power lines,
or put them in the same raceway. This can cause malfunction due to
induction.
●
Verify that the supply voltage variation is within the rating.
●
If power is supplied from a commercial switching regulator, ensure
that the frame ground (F.G.) terminal of the power supply is con-
nected to an actual ground.
●
If noise generating devices (switching regulators, inverter motors,
etc.) are used around the sensor mounting area, make sure to con-
nect the frame ground (FG) terminal of the device.
●
Do not use this product during the transient state when the power
supply is turned ON.
●
The overall length of the cable can be extended to 10m maximum
with a cable size of max. 0.3mm
2
.
●
Make sure that stress by forcible bend or pulling is not applied to the
sensor cable joint.
●
Although it depends on the type, light from rapid start type or high
frequency lighting type, fluorescent lights, sunlight and etc. may affect
the sensing, therefore make sure to prevent direct incident light.
●
This product is suitable for indoor use only.
● Keep water, oil, fingerprints and etc. which reflect light, dust or par
-
ticles etc. which interrupt the light, away from the emitting / receiving
surfaces of this product. If contaminants adhere to the surface, wipe
off with a dust-free soft cloth, or lens cleaning paper.
●
Do not use the sensor in locations where there is excessive vapor,
dust or etc. or in an atmosphere where corrosive gases, etc. are
generated.
●
Take care that the product does not come in contact with oil, grease,
organic solvents such as thinner, etc., strong acid or alkaline.
●
Make sure to turn OFF the power supply, before cleaning the light
emitting / receiving windows of the sensor head.
