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 details 

Switch setting 

Energy-saving 
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.
