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 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.
"3. Adjusting ion balance" (page 7)
■ Static elimination stop function
Static elimination can be turned ON/OFF with the device still powered. This is achieved by
disconnecting the trigger input and 0V terminals 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 8)
■ Air purge function
Dirt can be prevented from sticking to the electrode probe on the SJ-M040 by attaching a tube to the air
duct and supplying clean or dry air. This also extends the static elimination range.
