■ SJ-M Series Handling Precautions
The SJ-M Series isa high-voltage product that is not designed in an explosion-proof structure. Pay
attention to the following when using the SJ-M Series.
•
To prevent electric shock and to ensure accurate static elimination, be sure
to connect a Class D ground (maximum resistance of 100 Ohms).
•
The power cable supplied with the exclusive power supply (SJ-U2) is a 125 V
rated power cable. When connecting a power supply that exceeds this power
rating to the SJ-M Series, the user must prepare a power cable having
adequate voltage rating. If a power cable that does not meet the voltage
rating is used, this may cause electric shock, fire or malfunction.
•
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, tools, wire or other metallic objects near this

1-1 Features of the SJ-M Series
This section describes an outline of the functions, the features of the SJ-M Series.
Outline of the SJ-M Series
■ Pulse AC method
The SJ-M Seriesuses a pulse AC method that generates + and – chargedair ions from asingle
electrode probe. This system ensuresa maximum ion level per unit time, which in turn high-speed static
elimination. The SJ-M Series also automatically controls the level of + and – ions generated matched to
the chargedstate of the target obje
ct. This
enables high-speed and high-precision static elimination
suited to installation conditions.
■ I.C.C. (Ion Current Control) method
This control method calculates the charged level of the target object by sensing the state of ion current
that arises due to the potential difference between the electrode on the Static Elimination Head and
GND. Optimum static elimination matched to the state of the target object can be performed by rapidly
supplying the optimum ions suited to t
he polarity and charged level of the target object.
■ Ion monitor functions
●
Charge monitor
The integrated ion monitor allows you to learn how much the target object is chargedby + or – ions.
This monitor also allows you to confirm at a glance how static elimination is being performed.
● Ion level monitor
The ion level currently being generated by the Static Elimination Head is monitored atall times so that
drops in the generated ion level can be diagnosed on the unit. The generated ion level is indicated by
LEDs and an alarm can be output when the generated ions fall below a certain level. This allows you to
monitor the influence of a dirty electrode probe in advance.
"Ion Monitor Functions" (page 8)
A WARNING label is affixed on the SJ-M Series to ensure safety. Read the description on this
WARNING label to ensure correct use of the SJ-M Series.
WARNING labels in Japanese, German, French, Italian and Chinese (Simplified) are provided.
Use them as necessary.
■ Installation Precautions
CAUTION
■ About Warm-up
After turning the SJ-M Series ON, leave it for about 20 minutes to allow the ion
balance to stabilize.

Features of the SJ-M Series
■ Alarm output functions
●
Alarm output functions
An indicator blinks and an alarm signal is output, for example, when internal circuits are damaged or
abnormal discharging occurs. When an alarm signal is output, generation of ions is forcibly stopped.
● Ion level alarm output function
An indicator lights and an alarm signal is output when the level of generated ions drops due to a dirty
electrode probe, for example.
● Condition alarm output function
An indicator lights and an alarm signal is output when static elimination performance is impaired.
"Alarm Output Functions" (page 8)
■ Abnormal discharge detection function
Abnormal discharge caused by condensation on the electrode probe tip or adhesion of debris is
detected. When abnormal discharge is detected, ion generation is forcibly stopped to prevent trouble at
an early stage.
"Abnormal Discharge Detection Function" (page 8)
■ Ion balance adjustment function
The ion balance zero point can be fine-adjusted.
"3. Adjusting ion balance" (page 7)
■ Static elimination stop function
Static elimination can be turned ON/OFF with the device still powered. This is achieved by
disconnecting the trigger input and 0V terminals on the Controller Unit (I/O terminal section) or by
holding down the two ion-balance adjustment keyssimultaneously for about three seconds.
"Static Elimination Stop Function" (page 8)
■ Air purge function
Dirt can be prevented from sticking to the electrode probe on the SJ-M040 by attaching a tube to the air
duct and supplying clean or dry air. This also extends the static elimination range.

SJ-M Series Operations
3. Adjusting ion balance
The SJ-M Series automatically senses the charged level of the target body by the I.C.C. function to
automatically control the generated amount (balance) of plus and minus ions.
The zero point, the point for reference for the I.C.C. function, is adjusted before the SJ-M Series is
shipped from the factory. However, in some environments, the zero point sometimes drifts. If this
reference zero point drifts, adequate static elimination can
not be maintained. For this reason, you can
adjust the SJ-M Series to the desired zero point.
In Ion Balance Adjustment mode, you can adjust the zero point, the point for reference for the I.C.C.
function.
Do not turn the power OFF while the ion balance is being adjusted (while the
ion balance indicator is blinking fast).

3-2 Ion Monitor Functions
This section describes the ion monitor functions of the SJ-M Series.
Ion monitor functions are enabled in the Run mode.
Ion Monitor Functions
The charged level of the target object and the level of ions generated from the static elimination head
are indicated on the ion monitor.
The ion monitor indication can be switched by .
■ Charge monitor
This monitor indicates the charged and decharged
states of the target object.
The indication of this monitor fluctuates towards the
+ and – sides according to the charged level. The
further the indication is away from the center LED,
the larger the charged level. When static elimination
is completed, the indication returns to the center
LED so that you can easily tell how static
elimination is progressing.

3-3 Alarm Output Functions
This section describes the alarm output functions of the SJ-M Series.
Alarm Output Functions
■ Alarm output function (ALARM)
The alarm indicator blinks (red) and an alarm signal
(control output (N.C.)) is output, for example, when
internal circuits are damaged or abnormal discharging
occurs. When an alarm signal is output, static
elimination is forcibly stopped.
Alarm output turns ON even in a stati
c el
imination
stopped state (including forced static elimination stop).
■ Ion level alarm output function (ION LEVEL)
The ion level alarm indicator lightsand an alarm signal
(control output (N.O.)) is output when the level of
generated ions drops due to a dirty or worn electrode
probe, for example. When an alarm signal is output,
static elimination is not stopped.
Alarm output can be adjusted in three stages
according to the level of ions generated.
The default
setting for the ion level alarm sensitivity
setting is Low.
The ion level alarm serves as a guideline for learning
when to perform maintenance on the electrode probe.
As static elimination is continued, be sure to turn the
power OFF before starting maintenance on the
electrode probe.
The ion level alarm output function is enabled in the
Run mode.
"Ion level alarm sensitivity setup" (page 7)
■ Condition alarm output function (COND)
The condition alarm output indicator lights and an
alarm signal (control output (N.O.)) is output when
static elimination performance is influenced by an
excessive charge on the target object. When an alarm
signal is output, static elimination is not stopped.
Alarm output can be adjusted in three stages
acco
rdin
g to the installation environment. The default
setting for the condition alarm sensitivity setting is
Low.
The ion level alarm output function is enabled in the
Run mode.
"Condition alarm sensitivity setup" (page 7)
3-4 Other Functions
This section describes the abnormal discharge detection and static elimination stop functions of the SJM Series.
Abnormal Discharge Detection Function
Static Elimination Stop Function
You can turn off only static elimination while leaving the unit in a powered-on state by disconnecting the
trigger input and 0 V terminals on the Controller Unit (I/O terminal section), or by holding down
on the Controller Unit simultaneously (operation/display section) for about three seconds.
When static elimination stop input has been performed on the Controller Unit (operation/display
section), this state can be canceled by hol
ding down simultaneously for about three seconds.
For details on indication states on the Controller Unit (operation/display section) when static elimination
stop input is canceled, see "Static elimination stop input (operation/display section)" (page 12).
■ Stopping static elimination
Static elimination is stopped by either of the following methods.
By operation on the Controller Unit (I/O terminal section):
Disconnect the trigger input and 0 V terminals
to stop static elimination.
The center LED of the ion monitor blinks (red).

Air Purge Function
Dirt can be prevented from sticking to the electrode probe bysupplying clean or dry air from the air duct
of the static elimination head. This also extends the static elimination range.
* The pressure value at the neck of the air duct is indicated as the air pressure.
Use clean air or dry air of temperature –25°C, and of mesh size of about 0.01 μm.
To prevent trouble, the generation of ions is stopped when abnormal discharging causedby
condensation on the electrode probe tips or adhesion of debris, for example, is detected. At this time,
the alarm indicator and ion monitor blink to inform you that an abnormality has occurred. For details of
the indicated state on the Controller Unit (operation/display section), see "During an alarm (level
2)" (page 12).
By operation on the Controller Unit (operation/display section):
Hold down simultaneously for about three
seconds to stop static elimination.
The three center LEDs of the ion monitor blink
(red).
CAUTION
• Be sure to limit the air pressure to 0.7 MPa. Exceeding this limit may cause
accidents or malfunction.
• Be sure to use clean air, dry air as the air for supplying to the Static
Elimination Head. Moisture or oil contained in the air or nitrogen may cause
discharge inside the Static Elimination Head, which may result in accidents
or malfunction.

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.
•
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.
4-2
Performing Maintenance on the Electrode probe
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 electrode probe is used in a dirty or dusty state, static elimination performance can no longer be
fully demonstrated, resulting in accidents or malfunction. Be sure to periodically perform maintenance
on the electrode probe.
■ Replacing the electrode probe
If cleaning the electrode probe does not improve static elimination performance, or if the ion level alarm
indicator ligts frequently, replace the electrode probe.
An optional tungsten electrode probe (black) (OP-84383) is available.
● How to remove and install the electrode probe
Hold the plastic section of the electrode probe and turn it
counterclockwise to remove it. Then, turn it clockwise to
install it.
