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.

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.

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.

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).

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. 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 (green). The ion balance indicator lights when the ion level monitor is operating.
Ion level monitor indication is not available when I.C.C. is OFF. When I.C.C. is OFF, the ion balance indicator and ion level indicator 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. The center LED of the ion monitor blinks (red).

Other Functions
By operation on the Controller Unit (operation/display section):
Hold down simultaneously for about one second to stop static elimination. The three center LEDs of the ion monitor blink (red).

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.
Hold down for at least 1 second.

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.
WARNING
Important
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.
