■ Other Precautions
• Be sure to read the WARNINGS and CAUTIONS described in each of the
items in this Instruction Manual.
• This Static Eliminator has a built-in EEPROM. Do not turn the Static
Eliminator OFF during the setup.
Install the tip of the SJ-M010/020(G) paying attention to the following point.
●
Install the Static Elimination Head away from the wall or surrounding
objects.
● 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-M010/020(G) to rust, corrode or
deteriorate.
• Do not install the Static Elimination Head at locations where moving parts of
other equipment and machinery may place stress on the cable. Doing so
might cause the SJ-M010/020(G) to malfunction.

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.

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 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)
