■ General Precautions
• At startup and during operation, be sure to monitor the functions and
performance of the SJ-F300 Series.
• We recommend that you take substantial safety measures to avoid any
damage in the event that a problem occurs.
• Do not modify the SJ-F300 Series or use it in any way other than described
in the specifications. The functions and performance of products used or
modified in this way cannot be assured.
• When the SJ-F300 Series is used in combination with other instruments,
functions and performance may be degraded, depending on operating
conditions and the surrounding environment.
• Do not use the SJ-F300 Series for the purpose of protecting the human
body.
■ SJ-F300 Series Handling Precautions
The SJ-F300 Series is a high-voltage product that is not designed in an explosion-proof structure. Pay
attention to the following when using the SJ-F300 Series.
• To prevent electric shock and to ensure accurate static elimination, be sure
to connect a Class D earth (maximum resistance of 100 Ohms).
• Do not use this product in locations where there is the risk of ignition or
explosion from flammable solvents or dirt and dust.
• High voltage is applied to this product. Prevent it from being splashed with
water, oil, or flammable solvents. Failure to do so may cause insulation
breakdown, which will result in electric shock or malfunction.
• Do not bring your fingers or tools, wire or other metallic objects near this
product. Doing so may cause electric shock or malfunction.
• Do not use this product in a non-ventilated location. The ozone generated
from this product may become toxic. Be sure to ventilate the installation site
when this product is used in a non-ventilated location.
• Do not use this product in locations where sudden changes in temperature
or condensation are likely to occur. Doing so may cause accidents or
malfunction.
• Do not operate this product with wet hands. Doing so may cause electric
shock.
• Before starting maintenance, be sure to turn the power OFF. Failure to do so
may result in electric shock or accidents.
• During maintenance, do not directly touch the electrode needles. Doing so
may cause personal injury.
• If any malfunction is observed in this product, immediately turn it OFF, and
contact your nearest agent. You should never repair this product yourself.

Operation
Adjusting Ion Balance
The SJ-F300 Series senses the charged amount of the target object by the I.C.C. function to
automatically control the emission (balance) of plus and minus ions.
The zero point, the point for reference for the I.C.C. function, is adjusted before shipment. However, in
some environments, the zero point sometimes drifts. If this reference zero point drifts, adequate static
elimination cannot be maintained.
The SJ-F300 Series allows arbitrary adjustment of ion balance.
Follow one of the procedures below to adjust ion balance.
• Ion balance adjustment using the Controller Unit
• Ion balance adjustment using the Static Elimination Blower Unit
This section describes each adjustment procedure.
■ Ion balance adjustment using the Controller Unit
1 Press and hold and for about two seconds
simultaneously.
The ion level alarm indicator blinks and the ion balance
adjustment mode is selected.
2 Press or for about one second to adjust the ion
balance.
3 Press and simultaneously to complete the
setup.
• It takes about 30 seconds for the ion balance setting to be reflected after the setup
completed.
• In the case of adjustment using the Controller Unit, the ion balances of all the Static
Elimination Blower Units being in connection are adjusted collectively.
• In the case where two ore more Static Elimination Blower Units each having
different ion balance are connected, the difference is maintained during the
adjustment. Note that when the ion level reaches the threshold of the zero point,
the setting value will be the same at that value.
Every pressing for about one second moves the
zero point to the + side.
Every pressing for about one second moves the
zero point to the - side.

Refer to "Table of Indicated States" (page 12) for indicated states of the Controller Unit.
About Function When Static Elimination Blower Units Are Used in Connection
In the case where the Static Elimination Blower Units are used in connection, the blow rates and the ion
balances of all the units can be adjusted collectively from the Controller Unit.
■ Blow rate collective adjustment function
This function allows the blow rates of all the units being in connection to be increased or decreased
collectively.
Increasing the blow rate enables static elimination from a wider area.
Refer to "Adjusting Blow Rate of the Static Elimination Blower Unit" (page 7) for details about how to
adjust blow rate collectively.
■ Ion balance collective adjustment function
This function allows the ion balances of all the units being in connection to be adjusted collectively.
The SJ-F300 Series senses the charged amount of the target object by the I.C.C. function to
automatically control the emission (balance) of plus and minus ions.
The zero point, the point for reference for the I.C.C. function, is adjusted before shipment. However, in
some environments, the zero point sometimes drifts. If this reference zero point drifts, adequate static
elimination cannot be maintained. For this reason, it is necessary to adjust the SJ-F300 Series to a
desired zero point using this function.
Refer to "Adjusting Ion Balance" (page 7) for details about how to adjust ion balance collectively.
4MAINTENANCE
4-1 About Maintenance
Maintenance must be performed periodically to ensure that the static elimination performance of the
SJ-F300 Series is fully demonstrated. For maintenance, be sure to thoroughly read the descriptions
under "Safety Precautions" ( page 1), and pay attention to the following points.
About Maintenance
• The SJ-F300 Series uses high voltage. Before starting maintenance, be sure to turn
the power OFF. Failure to do so may result in electric shock or malfunction.
•
Do not directly touch the electrode needles.
Take care not to touch these needles even if
the power is turned OFF. Directly touching
these needles may cause personal injury.
When the SJ-F300 Series is used for a long period of time, the electrode needles become dirty due to
the adhesion of dust and dirt.
If the ion level alarm indicator lights, clean the electrode needles. If the electrode needles are used in a
dirty or dusty state, the static elimination performance can no longer be fully demonstrated, resulting in
accidents or malfunction. We recommend periodically cleaning the electrode needles (as a guideline,
once every two weeks in a regular operating environment though this depends on the installation
conditions).
If cleaning the electrode needles does not improve the static elimination performance, or the ion level
alarm indicator frequently lights, replace the Electrode Unit.
