Determining the Model and Settings 1 / Sensing DC Mode
1. Sensing DC mode (Refer to page 14 when using the ionizer in the pulse DC mode, or refer to page 18 when using it in the DC mode.)
1) Selection of bar length
· Select the appropriate length suited for a work size by referring to “Static electricity Removal Characteristics” and “Static electricity
Removal Range”, etc.
2) Installation of the ionizer
· Install within 200 to 2000 mm. Although the main unit can also be used at other distances, it may fail to operate normally depending
on the conditions of use. Before use, always verify that the main unit is functioning normally.
3) Installation of the sensor
· Install the feedback sensor with the detection hole facing the charged surface.
· Installation at a height from 10 to 50 mm is recommended. Although the sensor can also be used at other heights, it may fail to
operate normally depending on the conditions of use. Before use, always verify that the sensor operates normally.
(Refer to “Installation height of feedback sensor and discharge time/Ion balance” on page 2 as a guide.)
· When the ionizer and feedback sensor are connected, the sensing DC mode is automatically selected.
4) Configuration of dirt-detection level on an electrode needle
· Maintenance level selection switch
· Set the switch to either H (high), M (middle) or L (low). At settings other than these, the ionizer does not perform electrode needle
dirt-detection.
Note) Dirt-detection starts when the maintenance start signal is input.
5) Configuration of frequency selection switch
· Use this switch to select “Energy Saving Mode” or “Continuous Static Electricity Removal Mode”.
· This switch is used to select ion generation frequency for “Continuous Static Electricity Removal Mode,” after the completion of static
electricity removal.

Automatically stops emitting
electricity even after
completing the static electricity
removal.
Continously eliminates static
electricity with pulse DC by
controlling the ion balance so
that the charged potential on a
workpiece would be within ±30
V even after completing the
static electricity removal.
The ionizer generates ions at
the preset frequency.
H (High) Level that does not effect the discharge time.
M (Middle) Level immediately before the discharge time is extended.
L (Low) Level at which the discharge time is longer than it was initially.
