 Rapid elimination of static electricity by a feedback sensor
•
The speed of static electricity elimination has been increased by reading the workpiece’s
electrostatic potential by the feedback sensor and continuously emitting ions with a reverse polarity.
•
Operation mode after static electricity removal (ion balance: within ±30 V) can be selected.
Feedback sensor /
Rapid elimination of static electricity
Feedback sensor
Detects the polarity of a discharged object
and measures the charged voltage.
Energy saving operation mode: Stops generating ions after static electricity removal to reduce power
consumption. Air consumption can also be reduced by controlling a pneumatic valve with a
static electricity removal completion signal.
Note) The pneumatic valve must be separately procured.
Continuous static electricity removal operation mode: After static electricity elimination, the ionizer
changes to pulse DC mode and continues to eliminate static electricity to make it approach 0 V
even if the ion balance is below 30 V.

Autobalance sensor [Body-mounting type]
Ion balance adjustment trimmer
Functions
(1) Sensing DC mode
(2) Pulse DC mode
Alternatively emits positive and negative ions.
 When an autobalance sensor (high-precision type) is used.
 When an autobalance sensor (body-mounting type) is used.
(3) DC mode
 When a sensor is not used.
1. Operation mode
There are 3 different operation modes (Sensing DC mode/Pulse DC mode/DC mode) for Series IZS31, which can be selected
based on the application and operating condition.
Energy saving
mode
Continuous
static electricity
elimination mode
Note) When the feedback sensor is installed at a height of 25 mm.
Manual operation
Automatic operation
This method continuously adjusts the ion balance. For static electricity elimination from stationary
workpieces or spatial static electricity elimination, “Automatic Run” is recommended.
When a maintenance start signal is input or the ionizer is turned on, this method adjusts the ion balance. For
static electricity elimination from moving workpieces, “Manual Run” is recommended. Start system operation
after the completion of ion balance adjustment.
Series IZS31
Controls the initial ion balance. If the ion balance cannot be kept
due to electrode needle contamination, the ionizer outputs a
maintenance output signal. Use a balance adjustment trimmer to
set the ion balance (requires a separate measuring instrument to
verify the ion balance).
When an autobalance sensor is used, the ionizer automatically adjusts the ion balance to ±30 V.
If the ion balance exceeds ±30 V due to electrode needle contamination, the ionizer outputs a maintenance output signal.
The ion balance is adjusted and retained at the position of the workpiece. This mode is suited for eliminating spatial static
electricity or preventing workpieces from becoming electrostatically charged.
Either “Manual Operation” or “Automatic Operation” can be selected depending on the method of ion balance adjustment.
Use a balance adjustment trimmer to adjust the ion balance. This requires the separate use of a measuring
instrument to verify the ion balance.
Continuously emits positive and negative ions. Parts other than the workpiece need to be appropriately grounded to
prevent them from being charged. This mode cannot emit both positive and negative ions at the same time.
The discharge time is reduced by detecting the workpiece’s charge condition with a feedback sensor which feeds the data
back to the ionizer and causes ions with the polarity best suited for static electricity elimination to be emitted. The static
electricity elimination completion signal turns off when the workpiece’s electrostatic potential falls within ±30 V. Note)
This mode is suited for eliminating static electricity from heavily charged workpieces.
Either “Energy Saving Mode” or “Continuous Static Electricity Elimination Mode” can be selected depending on the
ionizer’s operation after static electricity elimination is completed.
Even after the completion of static electricity elimination, this method continues to eliminate static electricity using
DC pulses while controlling the ion balance, so that the workpiece’s electrostatic potential falls within ±30 V. Note)
For static electricity elimination from nonconductive workpieces, “Continuous Static Electricity Elimination Mode”
is recommended.
The ionizer stops discharging automatically after the of static electricity elimination is completed. It resumes
discharging when the workpiece’s electrostatic potential exceeds ±30 V. Note)
For static electricity elimination from conductive workpieces, “Energy Saving Mode” is recommended.

When a maintenance start signal is input, the ionizer detects any deterioration that may interfere with the electrode needles’
capability to eliminate static electricity. If the needles need to cleaning due to such deterioration, the maintenance
indicator
LED comes on and the maintenance output signal turns ON. Ion emission continues even if the maintenance
output signal is turned ON.
Note) Deterioration in the static electricity elimination capability cannot be detected by only connecting a feedback sensor, autobalance

Model Selection and Settings 1 / Sensing DC Mode
1. Sensing DC mode
(Refer to page 15 when using the ionizer in the pulse DC mode, or refer to page 19 when using it in the DC mode.)
1) Bar length selection
· Select the appropriate length suited for a workpiece size by referring to “Static Electricity Elimination Characteristics”
and “Static Electricity Elimination Range”.
2) Ionizer installation
· Install the ionizer within 200 to 2000 mm. Although the ionizer can also be used at other distances, it may fail to
operate normally depending on the conditions of use. Before use, always verify that the ionizer is functioning normally.
3) Sensor installation
· Install the feedback sensor with the detection hole facing the charged surface.
· Installation at a height from 10 to 50 mm is recommended. Although the sensor can also be used at other heights, it
may fail to operate normally depending on the conditions of use. Before use, always verify that the sensor operates
normally. (Refer to “Installation height of feedback sensor and discharge time/Ion balance” on page 3 as a guide.)
· When the ionizer and feedback sensor are connected, the sensing DC mode is automatically selected.
4) Contamination-detection level setting on an electrode needle
· Maintenance level selection switch
· Set the switch to either H (High), M (Middle), L (Low). At settings other than these, the ionizer does not perform the
electrode needle contamination-detection.
Note) Contamination-detection starts when a maintenance start signal is input.
5) Frequency selection switch setting
· Select “Energy Saving Mode” or “Continuous Static Electricity Elimination Mode”.
· In case of “Continuous Static Electricity Elimination Mode”, select the ion generation frequency after static electricity
elimination is completed.

Ionizer Series IZS31
Turned ON when the workpiece’s electrostatic potential is greater
than ±30 V or when electrode needle contamination is detected.
Turned ON in normal operation.
Turned OFF in case of high-voltage error, sensor error, CPU error.
Turned ON when electrode needle maintenance is necessary.

(NDL CHECK ALARM)
Ions are emitted from the ionizer to detect electrode needle contamination and the workpiece may therefore be electrostatically charged.
Perform this detection procedure in the absence of workpieces.

Turn the power supply OFF, solve the problem, then
turn the power supply on again. Alternatively, switch
the discharge stop signal from OFF to ON.
Turn the power supply OFF, solve the problem, then
turn the power supply on again. Alternatively, switch
the discharge stop signal from OFF to ON.
Turn the power supply OFF, solve the problem, then
turn the power supply on again. Alternatively, switch
the discharge stop signal from OFF to ON.
Turn the power supply OFF, clean or replace the
electrode needles, and turn the power supply on
again.
Occurrence of an abnormal current, such as high-
voltage leakage. The ionizer
stops ion emission,
turns on the HV ALARM indicator,
and turns OFF the
error signal (OUT3).
The feedback sensor has become unable to operate normally.
The ionizer stops ion emission, turns on the SNSR ALARM
indicator, and turns OFF the error signal (OUT3).
Failure in the CPU due to noise, etc. The ionizer stops ion
emission, all of the LED indicators blink, and turns OFF the
error signal (OUT3).
Electrode needle maintenance is necessary. The NDL
CHECK ALARM indicator comes on and a maintenance
output signal (OUT2) turns ON.
