■ 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.

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.

"Air Purge Function" (page 9)
