Feedback sensor/
Rapid neutralization of static electricity
•
The discharge speed has been increased by reading the workpiece’s
electrostatic potential by the feedback sensor and continuously emitting ions with a reverse polarity.
Rapid neutralization of static electricity by a feedback sensor
•
Run mode after static neutralization (electrostatic potential: within ±30 V) can be selected.
Energy saving run mode: Stops generating ions after static neutralization to reduce power
consumption. Air consumption can also be reduced by controlling the pneumatic valve with a
static neutralization completion signal.
Note) The pneumatic valve must be separately procured.
Continuous static neutralization run mode: After static neutralization, the ionizer switches to pulse
DC mode and continues to neutralize static electricity to make it approach 0 V even if the
electrostatic potential is within ±30 V.

Autobalance sensor
Measures the nearest offset voltage.
Autobalance sensor [High-precision type]
The mode can be selected from “Manual Run”mode
which performs adjustment only when connected,
and “Automatic Run”mode which always performs
adjustment while connected.
• The offset voltage near the workpiece is
accurately adjusted.
• Reduces the variation in the offset voltage of
the static neutralization area due to the effect
from the installation height and disturbance.
Autobalance sensor [Body-mounting type]
can be mounted on the body, and
can be installed in any places.
Monitoring +/– return current
The offset voltage in the initial state is
controlled so that the voltage is main-
tained at a constant value by monitoring
the ion emitted from the ionizer using the
ground line, and adjusting the + and - ion
supply rate.

Note) When the feedback sensor is installed at a height of 25 mm.
Manual run
Automatic run This method continuously adjusts the offset voltage. For static neutralization from stationary workpieces or
prescribed spatial static neutralization, “Automatic Run” is recommended.
Controls to keep the initial offset voltage. If the offset voltage
cannot be kept due to emitter contamination, the ionizer outputs a
maintenance detection signal. Use a balance adjustment trimmer
to set the offset voltage (requires a separate measuring instrument
to verify the offset voltage).
There are 3 different run modes (Sensing DC mode/Pulse DC mode/DC mode) for the IZS31, which can be selected
based on the application and operating condition.
The ionizer automatically adjusts the offset voltage of the static neutralization area to within ± 30 V. If the offset voltage
exceeds
± 30 V due to contamination of the emitter, the ionizer outputs the maintenance output signal. The offset voltage can
be adjusted and maintained at the workpiece position.
Either
“ Manual Run ” or “ Automatic Run ” can be selected depending on the operating method of the offset voltage adjustment.
Use a balance adjustment trimmer to adjust the offset voltage. This requires the separate use of a measuring
instrument to verify the offset voltage.
Continuously emits positive and negative ions. Parts other than the object need to be appropriately grounded to
prevent 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 neutralization to emit. The static
neutralization completion signal turns off when the workpiece’s electrostatic potential falls within ±30 V. Note)
This mode is suited for neutralizing static electricity from heavily charged workpieces.
Either “Energy Saving Run” or “Continuous Static Neutralization Run” can be selected depending on the ionizer’s
operation after static neutralization is completed.
When the maintenance detection signal is input, or the ionizer is turned ON, the offset voltage of the static
neutralization area is adjusted. In the case of the static neutralization of a moving workpiece, “Manual Run” is
recommended. Start the operation of the system after the offset voltage is adjusted.
Even after the completion of static neutralization, this method continues to neutralize static electricity using DC
pulses while feeding back the data, so that the workpiece’s electrostatic potential falls within 30 V.
Note)
For static neutralization from nonconductive workpieces, “Continuous Static Neutralization Run” is recommended.
The ionizer stops discharging automatically after the of static neutralization is completed. It resumes discharging
when the workpiece’s electrostatic potential becomes outside of ±30 V.
Note)
For static neutralization from conductive workpieces, “Energy Saving Run” is recommended.

Functionality differs depending on the run mode.
Refer to “Model Selection and Settings” on page 648, 652, 653, 656.
When a maintenance detection signal is input, the ionizer detects any deterioration that may interfere with the emitters’
capability to neutralize static electricity. If the emitters need to be cleaned due to such deterioration, the maintenance
detection indicator LED comes on and a maintenance detection signal turns ON. Ion emission continues even if the
maintenance detection signal is turned ON.
Note) Deterioration in static electricity neutralization capability cannot be detected by only connecting a feedback sensor, autobalance
sensor [high-precision type], or autobalance sensor [body-mounting type]. Verify the capability by periodically inputting a
maintenance start signal.

Model Selection and Settings 1/Sensing DC Mode
1. Sensing DC mode (Refer to page 652 when using the ionizer in the pulse DC mode, or refer to page 656 when using it in the DC mode.)
1) Bar length selection
· Select the appropriate length suited for a work size by referring to “Static Neutralization Characteristics” and “Static
Neutralization Range”, etc.
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/Offset voltage” on page 640 as a guide.)
· When the ionizer and feedback sensor are connected, the sensing DC mode is automatically selected.
4) Maintenance detection level setting
· Select the detection level of the maintenance period of the emitter with the maintenance detection 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
emitter stain-detection.
∗Settings with the same letter share
the same level.
H (High)········
M (Middle)····
L (Low)·········
Level that does not affect the discharge time.
Level at which the discharge time is a little bit longer
than it was initially.
Level that gives the alarm before static neutralization
cannot be performed.
Note) Stain-detection starts when a maintenance start signal is input.
5) Frequency selection switch setting
· Select “Energy Saving Run” or “Continuous Static Neutralization Run”.
· In case of “Continuous Static Neutralization Run”, select the ion generation frequency after static neutralization is
completed.
