„ Ion monitor function
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 Blower Unit 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 dirty electrode needles in advance.
"Ion Monitor Functions" (page 3-2)
„ 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 amount of generated ions drops due to dirty
electrode needles, for example.
Condition alarm output function
An indicator lights and an alarm signal is output when static elimination performance is influenced by an
unstable installation environment (temperature, humidity, surrounding metal objects, etc.)
"Alarm Output Functions" (page 3-3)
„ Abnormal discharge detection function
Abnormal discharge caused by condensation on the electrode needle tips 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 3-4)
„ Ion balance adjustment function
The ion balance zero point can be fine-adjusted.
"Ion Balance Adjustment Function" (page 3-4)
„ 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 3-6)
„ Low voltage power-saving wiring
Low-voltage wiring eliminates deterioration of cables caused by discharging and eliminates the influence
on surrounding devices. This enables you to build a highly reliable system.
