Warning
(1)
Keep operating ambient temp. range
Operating ambient temp. range is 0 to 50
o
C.
Even if ambient temp. is within spec. range,
environment with sharp temp. change will can form dew. Don’t use it there.
(2)
Environment to avoid
Do not operate nor store the product under following environment to avoid failure.
a. Ambient temp. is out of 0 to 50
o
C.
b. Ambient humidity is out of 35 to 85%RH.
c. Place with sudden sharp temp. change. which form dew.
d. Place containing corrosive gas, explosive gas, or volatile flammable object.
e. Atmosphere in which exposed to dust, conductive iron particle, oil mist, sodium, organic solvent,
swarf, particles and cutting fluid(water, liquid).
f. Place exposed to direct sunlight or radiation heat.
g. Place generate strong noise(strong electric field, strong magnetic field, place generates surge).
h. Place generates static electricity discharge other than from the ionizer. Place where static electricity
is charged to the sensor.
i. Please generates strong high frequency.
j. Place where thunder strike is possible.
k. Place applies direct vibration or impact to the sensor.
l. Condition where the sensor receive force or weight which deform the sensor.
(3)
Electrostatic sensor is not proof against electrical surges caused by lightning strike.
Appropriate protection measures should be taken by the users.
Caution
(1)
Periodic inspection
Periodic inspection is necessary to ensure operation without failure. Sensor shall be inspected by
experienced person with adequate knowledge.
(2)
Do not overhaul nor modify to avoid electric shock, failure, fire, etc. Overhauled or modified product
does not guarantee spec. function or performances.
Warning
(1)
Do not drop, hit nor apply excess impact(100m/s
2
or more).
Even if the appearance of electrostatic sensor is not damaged, internal parts will be damaged
resulting in malfunction.
(2)
Don’t handle with wet hand to avoid electric shock and accident.
(3)
Wait for 10min. or longer after applying the power.
Detected value may be unstable right after supplying the power.
(4)
The direct-current power supply to combine should use UL authorization power supply which is the
class 2 power supply based on UL1310 or the power supply is using the transformer of a class 2
based on UL1585.
