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)
