４．Selection and setting of equipment
4-１．Sensing DC mode
1. Selection of bar length
・Select the length applicable to work size base on static charge elimination area and static charge
elimination characteristics.
2. Installation of body
・Keep the distance between the ionizer and charged objects within 200 to 2000mm. Although the ionizer
can be mounted outside of this range, it may not operate properly depending on the operating conditions.
Therefore, be sure to check if the ionizer will operate properly.
3. Installation of the sensor
・Install the feed back sensor. Keep the detecting hole towards the charged face.
・It should be mounted within a 10 to 50mm of installation height. Although the ionizer can be mounted
outside of this range, it may not operate properly depending on the operating conditions. Therefore, be
sure to check if the sensor will operate properly.
・When the ionizer and feed back sensor are connected, the mode is automatically shifted to the sensing
DC mode.
4. Setting of the maintenance level selecting switch
・Set the level for detecting the dirt on the electrode needle.
・Select the level from H（High）, M（Middle） or L（Low）. The dirt on the electrode needle cannot be
detected with other levels.
・The dirt detection is done when the maintenance start-up signal is input.
5. Setting of frequency selection switch
・This switch is used to switch the [energy-saving operation] and [continuous static charge eliminating
operation].
・With [continuous static charge eliminating operation], the ion-production frequency needs to be
selected after the static charge elimination is completed.

operation When the static
charge elimination is
completed, the
ion-discharge-output
will automatically
stop.

Continuous
static charge
eliminating
operation The static charge
elimination continues
as controlling the ion
balance with pulse
DC even after the
static charge
elimination is
completed so that the
charged potential of
works maintains
+/-30V or less.
Ions are discharged
with the set
frequency. 0 ・・・ 1Hz
1 ・・・ 3Hz
2 ・・・ 5Hz
3 ・・・ 10Hｚ
4 ・・・ 15Hz
5 ・・・ 20Hz
6 ・・・ 30Hz
7 ・・・ 60Hz
H（High） ・・・ The level that doesn’t affect the static charge eliminating time (Even a small amount of
dirt can be detected).
M（Middle） ・・The level that can notify the maintenance just before the static charge elimination time becomes
slow.
L（Low） ・・・ The level that the static charge elimination time becomes slower than the one in the initial state.
