6. Be sure to ground the DC1 (-) lead wire [blue] of the power supply cable (Resistance between the lead
wire and the earth ground should be 100Ω or less.)
If the lead wire is not grounded, the ion balance will be unstable, and an electric shock may occur. At the
same time, the ionizer and power supply might be damaged.
2-2. Installation of sensor
1. Installation of sensor head
Feed back sensor
Keep the detecting hole of the sensor head towards the charged object to precisely detect the target’s
static charge. Keep the distance between the detecting hole and surface of the charged object within 10
to 50mm to prevent the sensor from coming in contact with the charged object. The detecting range and
sensor output will be changed depending on the installation distance.
Mount the sensor head with two pieces of M3 screws (sold separately).
As the sensor head case is connected to the GND, pay great
attention to the installation or power supply to prevent
short-circuit between the GND and 24V power supply.
The detecting hole is open to detect static electricity. When
foreign substances are intruded into the hole or tools come in
contact with the inside of the detecting hole, it leads to a
malfunction or damage of the sensor, resulting in an improper
detection of the static electricity. Therefore, do not put any
foreign substances in the detecting hole or touch it with a tool.
Do not pull a cable out of the sensor head. If the cable is
pulled with a strong force, the sensor head might be damaged
or its wires might be broken.
