(7)
Do not apply tape/seal to the body to avoid electrification which disables correct detection of
electrified potential.
(8)
Stop supplying the power to the electrostatic sensor during installation and adjustment.
(9)
Keep the distance for installation so that the sensor head is not charged. (See Effective inspection
distance : “4. Specification”)
The sensor head may be charged depending on potential of the subject. Charging of sensor head
may damage the sensor.
Caution
(1)
Install the electrostatic sensor apart from the wall(see drawing below).
Charged potential may not be measured correctly if walls exist in the range below
.
(2)
After installation, confirm if electrified potential is correctly measured.
(
Unit: mm
)
Detected value of electrified potential depends on ambient installation conditions. Confirm
detection condition of sensor electrified potential.
Warning
(1)
Ensure adequate electric capacity and voltage satisfying spec. value.
(2)
Only connect to SELV circuit type power supplies,which have reinforced insulation to the low voltage
mains of the building installation.(SELV according to EN60950-1)
(3)
Ensure safety of wiring and surrounding conditions before supplying power.
(4)
Do not connect/remove wiring with power supplied to avoid the malfunction of the electrostatic
sensor. Cut power supply whenever wires(including plugging and removing the connector).
(5)
Using power lines and high voltage line in one system causes malfunction due to noise. Use them
separately.
(6)
Ensure no mistake on wiring before starting operation. Incorrect wiring lead to cause product
damage and malfunction.
Application of DC24V from the sensor output directly leads to the breakage of internal circuit.
