CAUTIONS DURING SETTING
Procedure for setting the sensor head
●
While watching the measuring range indicator LED,
・
set the sensor head so that the distance to the sub-
ject body is within the measuring range.
It may light up or blink even with a significant error in
the measuring range when the alarm is enabled.
・Be careful of the sensor head's orientation during mounting. When the subject body moves as shown below, er-
rors will develop depending on the orientation of the sensor head. In order to minimize these errors, be sure to
mount the sensor head in the correct orientation.
■Eccentricity measurement
Not good
・Confirm the mutual interference area when using sensors side
by side.

CLASS 1 LASER PRODUCT
LASER APERTURE Mounting the sensor head
●
Using two mounting holes, firmly mount the sensor head so that the sensor head's front surface is parallel to
・
the target. Do not tighten the installation screws to a torque over 2N・m.
Glass is used at the sensor head's light emitting and light receiving surfaces and, therefore, never subject it to impacts of any kind. Al-
・
so, be very careful not to allow oils, finger prints, or other substances that may refract the light, to get on the glass during mounting.
If light reflected off the target is then reflected off nearby objects or walls and then received by the sensor head,
・
the sensor head reading will be adversely affected. To prevent this, either further separate the sensor head or
apply a black delustering paint to prevent the unwanted reflection of light.
Mounting the controller
●
When mounting more than one controllers in a row, maintain at least 10m between each unit. Also, when
・
mounting the controller inside control panels or areas where the air is not properly ventilated, the controller will
LASER RADIATION cause the ambient temperature to rise. In these cases, ensure cooling facilities.

LASER APERTURE
and documents that came with the instrument. Also, to protect the inner circui-
try, arrange the lead wire that is not interconnected in a way so that it does not
come into contact with other lead wires.
When mounting or removing a connector, always first turn off the controller and
・
then begin operations.
All connectors are of the lock-on type. When connecting a connector, be sure to
・
securely insert it until it locks into place. When removing a connector, first press
in the lock release button on the connector side and then remove the connector.
After removing a connector, do not touch the terminals located inside.
・
Cable
●
When the sensor head and controller are fixed and cables connected, do
・
not subject the cables to a pull of more than 29.4N. Have no bends in the
cables with a radius of less than 20mm. Also, do not bend a sensor head's
cable near where the cable is attached to the sensor head.
When the sensor head is to be moved while in use, do not have it so that
・
the sensor head's cable becomes bent. If the location is such that it cannot
be helped, we recommend purchasing the appropriate length extension
cable. (ANR12□)

CAUTIONS
Operating environment
●
Use in an ambient temperature between 0 to +50℃. Store in a location where the temperature stays between
・
-20 to +70℃.
Use in an ambient humidity between 35 to 85% RH. Avoid use in locations with drastic humidity changes which
・
cause condensation.
Use in locations where the illuminance from incandescent lamps received at the light receiving surface is below
・
2,500 lx (ANR11□ and ANR1226), or below 3,000lx (ANR1250, ANR1251, ANR1282, ANR1215).
Also, locate the unit so that sunlight, does not directly hit the beam-receiving part.
When exceptional accuracy is required, mount a shielding plate or other type of shading mechanism.
The power supply voltage should be between 85 to 110% of the rated voltage.
・
Since the internal circuits may become damaged if an external surge voltage exceeds 500V [±(1.2×50)μs
・
unipolar full-wave voltage], always use a surge absorber or surge absorbing element.
Keep the sensor head beam-emitting part and beam-receiving part surface clean and free of moisture, oil, fin-
・
ger prints, and other light refracting substances, and free of dust, dirt, and other light blocking substances.
When cleaning the glass surfaces, wipe with a soft cloth or lens cleaning paper.
Although the sensor head is of water proof construction, it does not mean that measurements can be taken un-
・
derwater or in the rain. Moreover, the connectors are not watertight.
Do not use the unit in locations with flammable or corrosive gases, locations with excessive dust, locations
・
splashed by water, or locations subjected to vibrations or excessive shocks.
Since the controller contains molded resins, do not use in environments that contain, or where contact with,
・
benzene, thinners, alcohols and other organic solvents; and ammonia, caustic sodas, and other alkaline sub-
stances is possible.
Noise precautions
●
The connector's metal portion is internally connected to the analog output GND. In order to prevent affects from
・
noise or damage to the internal circuits, be sure
Ground the metal case of the sensor head to the frame ground (F.G.) of an equipment.
Mount the unit as far away as possible from high voltage lines, power lines, or devices that generate large switch-
・
ing surges.
Separate the sensor head cable wiring, high voltage circuit, and power circuit.
・
If there is much noise on the power supply, it will affect the analog output. In such cases, use a noise filter or
・
noise cut transformer.
Insulation resistance and voltage withstandability
●
Do not perform insulation resistance or withstand voltage tests between the connector's metal portion and input / outputs.
・
Power supply
●
Select a power supply with a ripple voltage below 0.5V (P-P) and a current capacity above 0.3A.
・
In order to avoid high-frequency noises when using a commercially available switching regulator, be sure to
・
ground the frame ground (F.G.) terminal.
When using a power supply that uses a transformer, be sure to use an insulated transformer. When using an
・
autotransformer (single-wound transformer), it is possible to damage this unit or the power supply.
Do not turn the power on again within 10 sec.after turning the power off.
・
In case of using this product as a CE marking conformity product, cable extension of the power wire and I/O wire
must be wthin 30m.
Warm-up time
●
Allow at least 30 minutes, after turning on the unit, for the unit to properly warm up.
