Tip
Adjusting Ion Balance
The SJ-F031/036 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-F031/036 allows arbitrary adjustment of ion balance.

About Maintenance
WARNING
When the SJ-F031/036 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 blinks, 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 blinks, replace the Electrode Unit.

When the condition alarm is output,
removing the cause of the alarm can
restore the normal state. One way of
restoring the normal state is to
enhance the installation
environment.
When the alarm is output, the
normal state can be restored by
performing one of the two available
restore methods depending on the
cause of alarm output.
For details on how to restore the
normal state, see "During an
