Safety Precautions
■ General Precautions
• At startup and during operation, be sure to monitor the functions and
performance of the SJ-M 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-M 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-M Series is used in combination with other instruments,
functions and performance may be degraded, depending on operating
conditions and the surrounding environment. Use the SJ-M after fully
studying the effect of combined use with other instruments.
• Do not use the SJ-M Series for the purpose of protecting the human body.
■ SJ-M Series Handling Precautions
The SJ-M Series is a 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 earth (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
product. Doing so may cause electric shock or malfunction.
•
Protect the area around the tip of the Static Elimination Head with silicon,
fluoro-resin or other highly ozone-resistant resin. Ozone that is generated
may cause the metal or resin on the SJ-M Series to rust, corrode or
deteriorate.
The ozone generated from this product may adversely affect the human
body. For this reason, do not use the SJ-M Series in closed spaces. Be sure
to use the SJ-M Series in a well-ventilated location. Also, do not bring your
face close to the Static Elimination Head. The ozone generated from this
product might be painful to your nose or throat.
•
Do not use this product in locations where sudden changes in temperature
or condensation are likely to occur.
•
Do not operate this product with wet hands. Doing so may cause electric
shock.
•
Before starting inspection or maintenance, be sure to turn the power OFF.
Failure to do so might result in electric shock or malfunction.
•
During maintenance, do not directly touch the electrode probe. 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.
Doing so may cause electric shock or malfunction.
• Do not touch the electrode probe with a tool or other hard object. Damage to
the electrode probe will prevent static elimination performance from being
fully demonstrated, and cause accidents or malfunction.
• When this product is used for a long period of time, the electrode probe
become dirty due to the adhesion of dust and dirt. If the ion level alarm
indicator or condition alarm indicator lights, clean the electrode probe. If the
product is used with the electrode probe 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 probe (as a guideline, once every two weeks in a regular operating
environment though this depends on the installation conditions).
• Do not drop or subject this product to shock. Doing so might result in
accident or malfunction.
• Use this product for static elimination only. Do not use it for other purposes.
• When installing the SJ-M Series, observe the minimum bending radius of all
provided cables. Also, do not install the SJ-M with the cables deformed by
staples or other objects. Doing so might cause the SJ-M to malfunction.
■ Power Supply Precautions
• Use a DC power supply with rated 24 V output.
• Noise applied to the power supply may cause this product to malfunction. If
this happens, install an insulated transformer.
• When using a switching regulator, be sure to connect a Class D earth to the
Frame Ground terminal.
■ Grounding Precautions
• To ensure safety and appropriate static elimination, be sure to ground this
product.
• Be sure to connect a Class D earth (maximum resistance of 100 Ohms)
■ Air Purge Function Precautions
• Be sure to use air of pressure to 0.2 MPa. Use outside of the rated air
pressure range might result in accidents or malfunction.
• Be sure to supply clean or dry air of temperature –20°C or more through a
filter of mesh size about 0.01μm. Moisture or oil contained in the air or
nitrogen may cause discharge inside the Static Elimination Head, which
may result in accidents or malfunction.
■ SJ-M Series Warning label
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.

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 Series uses a pulse AC method that generates + and – charged air ions from a single
electrode probe. This system ensures a 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 charged state of the target object. 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 the polarity and charged level of the target object.
■ Versatile frequency settings
A variety of frequencies can be set for the SJ-R. This allows optimal static elimination according to the
distance and the strength of the electric charge of the target.
■ Ion monitor functions
●
Charge monitor
The integrated ion monitor allows you to learn how much the target object is charged by + 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 at all 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.

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.
"Ion Balance Adjustment Function" (page 7)
■ Static elimination stop function
Static elimination only can be turned ON/OFF with the device still powered. This is achieved by shorting
the 0V terminal with the static elimination stop input terminal on the Controller Unit (I/O terminal
section) or by holding down the two ion balance adjustment keys simultaneously for about one second.
"Static Elimination Stop Function" (page 8)
■ Air purge function
Dirt can be prevented from sticking to the electrode probe on the SJ-M030 by attaching a joint to the air
duct of the Static Elimination Bar and supplying clean dry air from the air compressor. This also extends
the static elimination range.

Before Installation
■ Proper static elimination
To e ns ure proper static elimination, consider the following points.
If the target is in contact with metallic objects (grounding
conductor), the static charge of the target is not completely
eliminated.
Install the SJ-M Series in a location in which the target is not in
contact with any metallic objects (such as a grounding conductor).
If the film or sheet is an electrical insulator, only the static
electricity on the surface exposed to the static elimination bar
is eliminated.
To eliminate the static electricity on both surfaces, use another
SJ-M unit on the other side.
Precautions for installation
■ Locations
Refer to the following illustration to install the SJ-M Series.
• Provide enough space between the static elimination bar and surrounding
walls as shown in the figures below.
•
When mounting the SJ-M Series, use the provided mounting bracket,
otherwise an accident or malfunction may result.

SJ-M Series Operations
Ion Balance Manual Adjustment Mode
In this mode, you can adjust the zero point, the point for reference for the I.C.C. function.
Ion Balance Adjustment Function
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 cannot be maintained. For this reason, you need
to adjust the zero point again by “Ion Balance Adjustment Function”.
Do not turn the power OFF while the ion balance is being adjusted (about 1
minute).

■ 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.
The ion balance indicator lights when the charge
monitor is operating.
■ Ion level monitor
This monitor indicates the level of ions being
generated by the Static Elimination Head.
The level of plus ions being generated is indicated
on the upper side, while the level of minus ions is
indicated on the lower side. The further the
indication is away from the center LED, the larger
the level of ions. In a state where ions are being
sufficiently generated, both ends of this monitor light

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 static elimination
stopped state (including forced static elimination stop).
■ Ion level alarm output function (ION LEVEL)
The ion level alarm indicator lights and 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
according 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
To prevent trouble, the generation of ions is stopped when abnormal discharging caused by
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 13).
Static Elimination Stop Function
Static elimination only can be turned OFF in a powered ON state by two methods: by shorting the static
elimination stop input and 0V terminals on the Controller Unit (I/O terminal section), or by holding down
on the Controller Unit (operation/display section) simultaneously for about one second.
When static elimination stop input has been performed on the Controller Unit (operation/display
section), this state can be canceled by holding down simultaneously for about one second.
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 13).
■ Static elimination stop input
Static elimination is stopped by either of the following methods.
By operation on the Controller Unit (I/O terminal section):
Short the static elimination stop input and 0V
terminals to stop static elimination.

Other Functions
By operation on the Controller Unit (operation/display section):

second to stop static elimination.
The three center LEDs of the ion monitor blink

Air Purge Function
Supplying clean air through the air duct on both ends of the static elimination bar will prevent the dust
accumulation on the electrode probes (SJ-M0
*
0G/V type). The air purge widens the static elimination
area and increases the speed of static elimination as well.
* The air pressure indicates the pneumatic value at the route of the joint.
Use clean air or dry air of temperature –25°C, and of mesh size of about 0.01 μm.
When supplying air to the SJSJ-G, SJ-V/VC Series, you can use the active carbon filter to decrease
the dust accumulation on the electrode probes.
• Be sure to limit the air pressure to 0.2 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.
■ Relationship between air pressure and air flow with different bar lengths
The relationship between air pressure and air flow varies depending on the length of the static
elimination bar.
Refer to the typical example below to select the appropriate air supply device (compressor) that will
supply sufficient air flow.

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.
If I.C.C. is set to OFF, the ion level alarm can not be judged correctly.
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.
Performing Maintenance on the Electrode probe
• At the time of maintenance, turn the SJ-M Series OFF.
• Do not directly touch the electrode probe with your hands. Doing so may
cause personal injury. Pay attention to this when performing maintenance
on the electrode probe.
■ How to clean the electrode probe
Clean the electrode probe gently with a cotton
wool bud moistened with alcohol.
■ How to replace the electrode probe
If the static elimination performance of an electrode probe does not recover or the ION LEVEL indicator
is lit frequently after cleaning, the life of the electrode probemay be expired. In that case, replace the
electrode probe.
Use the tungsten electrode probe as spares for SJ-G Series.
Replace all the remaining electrode probes along with the bad one, regardless of whether the
remaining electrode probes are still in serviseable condition or not.
