■ Relationship between installation distance and wind speed according to air
flow rate
The relationship between wind speed and static elimination head installation distance varies according
to the air flow rate
Adjust the air supply flow rate referring to the following figures.

■ How to supply air
Supply air from the SJ-M010/020(G)'s Air Input Unit as
shown in the figure on the right.
Joints and tubes must be prepared separately.
●
Recommended joint
We recommend using a tube fitting (tube dia. 6mm, 8mm) made by PISCO for a joint to the Air Input
Unit.
• Be sure to limit the tightening torque to 0.7 Nm. Tightening beyond this limit
may cause an accident or a malfunction.
• Be sure to use the Air Input Unit. Using a different air supply may cause an
accident or a malfunction.

I.C.C. Setting
The I.C.C. (Ion Current Control) can be turned on and off.
Turning off the I.C.C. allows the ion balance adjustment function to generate positive and negative ions
at a fixed ratio.

On the ion monitor, the currently selected items are lit in green and the
items whose default have been changed are lit in red.
I.C.C. is set at ON by default setting.
Items that satisfy both of these conditions blink in red and green
alternately.
Advance to the tube head setting from the Select mode in page 7, and
select either of the followings.
(1) Normal nozzle (green) (Default)
(2) Tube nozzle (red)
Select an appropriate nozzle according to the
head. Incorrect setting may cause accidents or
malfunction. When the tube nozzle is selected, the
ion level alarm will not be output correctly.

4-1 About Maintenance
Maintenance must be performed periodically to ensure that the static elimination performance of the
SJ-M Series is fully demonstrated. Maintenance personnel should thoroughly read the descriptions
under "Safety Precautions" (
page 1), and perform maintenance paying attention to the following
points.
About Maintenance
• The SJ-M Series uses high voltage. Before starting maintenance, be sure to
turn the power OFF. Failure to do so might result in electric shock or
malfunction.
• Do not directly touch the electrode
probe. Take care not to touch these
probes even if the power is turned OFF.
Directly touching these probes may
cause personal injury.
When the SJ-M Series is used for a long period of time, the electrode probe becomes dirty due to the
adhesion of dust and dirt.
If the ion level alarm indicator lights, clean the electrode probe. If the electrode probe is used in a dirty
or dusty state, static elimination performance can no longer be fully demonstrated, resulting in
accidents or malfunction. We recommend periodically cleaning the electrode probe (as a guideline,
once every two weeks in a regular operating environment though this depends on the installation
conditions).
If cleaning the electrode probe does not improve the static elimination performance, or the ion level
alarm indicator frequently lights, replace the electrode probe.
