1-1 Features of the SJ-M Series

This section describes an outline of the functions and 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, and therefore high-speed static elimination. The SJ-M Series also automatically controls the level of + and – ions generated based on the charged state of the target object. This enables high-speed and high-precision static elimination.

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 based on 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 see 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.

1-1 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 10)

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 malfunction at an early stage.

"Abnormal Discharge Detection Function" (page 10)

Ion balance adjustment function

The ion balance zero point can be fine-tuned.

"Ion Balance Adjustment Function" (page 9)

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 10)

Air purge function

Dirt can be prevented from sticking to the electrode probe on the SJ-M021(G) by attaching a tube to the air duct and supplying clean, dry air. This also extends the static elimination range.

"Air Purge Function" (page 10)

High-temperature static elimination

The High Temperature global setting allows static to be eliminated in hot environments. (ambient operating temperature: SJ-M021(G), 0 to +80°C)

"High temperature use setting" (page 8)

2-1 Before Installation

This section describes the static elimination performance of the SJ-M201 Series.

Before you install the SJ-M201 Series, fully calculate the distance between the Static Elimination Head up to the target object and the time required for static elimination.

About Static Elimination Performance

The following shows a typical example where static is eliminated from an aluminum plate (20 pF) 150 x 150 mm square, charged to +1000 V, by the SJ-M201 Series.

Static elimination time

The following graphs show typical examples of the relationship between static elimination time and static charged voltage.

Measurement condition: Applied voltage +1000 V

150 mm x 150 mm plate monitor (20 pF) used Installation distance 300 mm
