■ 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.

•

Supply air according to the deratings indicated in the specifications. Use without performing derating might result in electric shock or malfunction

•

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.

CAUTION

WARNING

• 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).

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.

■ 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 9)

■ 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 9)

■ Ion balance adjustment function

The ion balance zero point can be fine-adjusted.

"Ion Balance Adjustment Function" (page 8)

■ 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 three seconds.

"Static Elimination Stop Function" (page 9)

■ Air purge function

Dirt can be prevented from sticking to the electrode probe on the SJ-M010/020 (G) by attaching a tube to the air duct and supplying clean or dry air. This also extends the static elimination range.

"Air Purge Function" (page 9)

■ High-temperature static elimination

The High Temperature mode allows static to be eliminated in hot environments. (ambient operating temperature: SJ-M010/020 (G), 0 to +80°C)

"High temperature use setting" (page 7)

Before Installation

■ Appropriate static elimination method

Pay attention to the following points to ensure that static elimination is performed appropriately.

Static elimination cannot be performed accurately at locations where the target object is touching a metallic body (earthed body).

Eliminate static from the target object at locations where it is not directly touching metallic bodied (earthed body).

Static will be eliminated from only the surface of the insulated body (board, etc.) that is facing the Static Elimination Head.

When eliminating static from both sides of a target object, install two SJ-M Series as one SJ-M Series must be installed on either side of the target object.

Install the Static Elimination Head so that it can be easily accessed, for example, for replacement of parts and cleaning.

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 can adjust the SJ-M Series to the desired zero point.

Do not turn the power OFF while the ion balance is being adjusted (about 1 minute).

■ Setting the ion balance

1 Hold down for at least one second to enter the ion

balance manual adjustment mode.

The ion balance indicator blinks.

CAUTION

Hold down for at least 1 second.

After you have finished setting up the ion balance, do not change the ambient environment for about 1 minute. If you do, the zero point sometimes cannot be set accurately.

Note

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.

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 14).

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 three seconds. 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 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 14).

■ 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).

"Controller Unit (I/O terminal section)" (page

To 24 VDC power supply

3-4

Other Functions

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).

Air Purge Function

Clean air, dry air must be supplied to the SJ-M010/020(G) from the Air Input Unit. The air purge performs two roles. It prevents dirt from sticking to the electrode probe and extends the static elimination area. * 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.

• Be sure to limit the air pressure to 0.5 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 press and flow rate

The figure on the right shows the relationship between the flow rate and pressure of the

Supply air from the SJ-M010/020(G)'s Air Input Unit as shown in the figure on the right. Joints and tubes must be prepared separately.

● Recommended joint

We recommend using a tube fitting (tube dia. 6mm, 8mm) made by PISCO for a joint to the Air Input Unit.

• Be sure to limit the tightening torque to 0.7 Nm. Tightening beyond this limit

may cause an accident or a malfunction.

• Be sure to use the Air Input Unit. Using a different air supply may cause an

accident or a malfunction.

4-1 About Maintenance

Maintenance must be performed periodically to ensure that the static elimination performance of the SJ-M Series is fu lly 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.

WARNING

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

• Before removing the Electrode Unit, 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

Note: If cleaning the electrode probe does not improve static elimination performance, or the ion level alarm indicator frequently lights, a probable cause is that the electrode probe has reached the end of its service life. Electrode replacement units for SJ-M020 (OP-51607) and for SJ-M020G (OP-75351) are available in options.

● How to remove and install the electrode probe

The electrode probe can be removed by holding the tip of the electrode probe and turning counterclockwise, and installed by turning clockwise.

WARNING

Rotate while holding this area.
