■ SJ-M Series Warning label
A WARNING label is affixed on the SJ-M Series to ensure safety. Read the description on this
WARNING label to ensure correct use of the SJ-M Series.
■ Installation Precautions
Avoid installing the SJ-M Series in the following locations as this may cause
accidents.
• Locations directly subject to vibration and shock
• Locations subject to ambient temperature outside of the 0°C to +40°C range
• Locations subject to ambient humidity outside of the 35 to 65%RH range
(condensation not allowed)
• Locations subject to sudden changes in temperature
• Locations subject directly to blasts from air conditioners
• Locations subject to volatile or flammable substance, solvents or corrosive
gases
• Locations subject to large amounts of dirt, and dust, salt, iron and oil smoke
• Locations that may be splashed with water, oil or chemical mist
• Locations where strong magnetic and electrical fields are generated
■ About Warm-up
After turning the SJ-M Series ON, leave it for about 20 minutes to allow the ion
balance to stabilize.
WARNING labels in Japanese, German, French, Italian and Chinese (Simplified) are provided.
Use them as necessary.

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.
