Precautions during operation
1. Operating environment
1) Use in an ambient temperature
between 0 °C 32 °F and 50 °C 122 °F.
Store in a location where the tempera-
ture stays between –20 °C –4 °F and
70 °C 158 °F.
2) Use in an ambient humidity between
35 % and 85 % RH. Avoid use in loca-
tions with drastic humidity changes
which cause condensation.
3) Use in a location where the illumi-
nance from incandescent lamps received
at the light receptors surface is below
2,500 lx (ANR11 series and ANR1226),
or below 3,000 lx (ANR1250, ANR1251,
ANR1282, and ANR1215). Also, locate
the unit so that sunlight, light of the same
wavelength, or other disturbing light,
does not directly hit the light receptor.
When exceptional accuracy is required,
install a shielding plate or other type of
shading mechanism.
4) The power supply voltage should be
between 85 % and 110 % of the rated
voltage.
5) Since the internal circuits may
become damaged if an external surge
voltage exceeds 500 V [±(1.2 ×50) µs
unipolar full-wave voltage], always use a
surge absorber or surge absorbing ele-
ment.
6) Keep the sensor light emitter and light
receptor surface clean and free of mois-
ture, oil, finger 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.
7) Although the sensor is of waterproof
construction, it does not mean that mea-
surements can be taken underwater or in
the rain. Moreover, the connectors are
not watertight.
8) Do not use the unit in locations with
flammable or corrosive gases, locations
with excessive dust, locations splashed
by water, or locations subjected to vibra-
tions or excessive shocks.
9) Since the controller contains molded
resins, do not use in environments that
contain, or where contact with, benzene,
thinners, alcohols and other organic sol-
vents; and ammonia, caustic sodas, and
other alkaline substances is possible.
2. Noise precautions
1) Install the unit as far away as possible
from high voltage wires, power wires, or
devices that generate large switching
surges.
2) Separate the sensor cable wiring, high
voltage circuit, and power circuit.
3) 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.
3. Insulation resistance and withstand
voltage
1) Do not perform insulation resistance
or withstand voltage tests between the
connector’s metal portions and input/out-
puts.
4. Power supply
1) Select a power supply with a ripple
voltage below 0.5 V (P-P) and a current
capacity above 0.3 A.
2) In order to avoid high-frequency nois-
es when using an off-the-market switch-
ing regulator, be sure to ground the
frame ground (FG) terminal.
3) When using a power supply that uses
a transformer, be sure to use an insulat-
ed transformer. When using an auto-
transformer (single-wound transformer),
it is possible to damage this unit or the
power supply.
5. Warm-up time
1) Allow at least 30 minutes, after turning
on the unit, for the unit to properly warm
up.
Area of interference
When using more than one sensor
together, be careful of the area of inter-
ference.
