„
Keep the detecting hole of the sensor head towards the charged object to precisely detect the target’s
static charge. Keep the distance between the detecting hole and surface of the charged object within 10
to 50mm to prevent the sensor from coming in contact with the charged object. The detecting range and
sensor output will be changed depending on the installation distance.
Mount the sensor head with two pieces of M3 screws (sold separately).
M3 screws
As the sensor head case is connected to the GND, pay great
attention to the installation or power supply to prevent
short-circuit between the GND and 24V power supply.
The detecting hole is open to detect static electricity. When
foreign substances are intruded into the hole or tools come in
contact with the inside of the detecting hole, it leads to a
malfunction or damage of the sensor, resulting in an improper
detection of the static electricity. Therefore, do not put any
foreign substances in the detecting hole or touch it with a tool.
Do not pull a cable out of the sensor head. If the cable is
pulled with a strong force, the sensor head might be damaged
or its wires might be broken.

Auto balance sensor
Horizontally place the auto balance sensor under the ionizer and face its metal plate upward. Because
the ion balance will be changed depending on the installation height, install the sensor on the same level
with a workpiece as much as possible. The auto balance sensor can be removed once the ion balance
adjustment is completed.
Keep the height between the auto balance sensor and ionizer within the installation height stated in
2-1.
Mount the head sensor with 2 pieces of M3 screws (sold separately).

2. Installation of sensor amp
A sensor amp should be mounted with 2 pieces of M3 screws (sold separately).
Do not pull a cable out of the sensor amp. If the cable is pulled with a strong force, the sensor amp might
be damaged or its wires might be broken.
Be sure to ground the sensor amp case. (Resistance between the sensor amp case and the earth
ground should be 100Ω or less.) Because the sensor amp case surface is treated with conductive
plating, FG wiring is not necessary when the sensor amp case is connected to the mounting surface of the
grounded unit. If the mounting surface is insulated with painting or being anodized, be sure to connect the
FG wiring for grounding.

3. Function description
3-1. Operation mode
3 types of operation modes are available with IZS31 (sensing DC mode, pulse DC mode and DC mode.)
These modes are selectable depending on the applications and operating conditions.
1. Sensing DC mode
This mode detects the charged condition of the workpiece with the feed back sensor, and feed back the
condition to the ionizer. With this mode, ions with optimal polarity are discharged to shorten the static
charge elimination time. When the static charged of the workpiece becomes +/-30V or less note), the
completion signal of the static charge elimination will turn off.
This mode is suitable for the object that is largely charged.
Once the static charge elimination is completed, [energy-saving operation] or [continuous static charge
elimination mode] can be selected.
Energy-saving
operation
The ion-discharge output will automatically stop once the static charge
elimination is completed. If the charged potential of the work becomes +/- 30 V
or more, the ion will be discharged again.
The [energy-saving operation] is recommended for conductive workpieces.
The static charge will be continuously eliminated with pulse DC as maintaining
the ion balance to make the charged potential +/-30V or less note) even after the
static charge is completed.
The [continuous static charge eliminating operation] is recommended for
nonconductive workpieces.
Continuous
static charge
eliminating
operation
Note) when the installation height of the feed back sensor is 25mm.
2. Pulse DC mode
The ionizer discharges plus ions and minus ions by turns.
When the auto balance sensor is used, the ion balance is automatically adjusted within +/-30V. If the ion
balance exceeds +/-30V due to the dirt on the electrode needle, the maintenance output signal will be
output.
This mode is suitable for eliminating the static charge in the air and/or on the workpieces.
„
When the auto balance sensor is used.
[Manual operation] or [auto operation] can be selected for the ion balance adjustment.
Manual
operation
When maintenance start-up signal is input, or the power supply of the ionizer
Is applied, the ion balance adjustment will begin.
When workpieces are moving, [manual operation] is recommended. Start the
equipment after ion balance is adjusted.
Auto operation
The ion balance is continuously adjusted.
When the static charge of the still workpieces or in the atmosphere is
eliminated, the [auto operation] is recommended.
„
When the auto balance sensor is not used.
The ion balance is adjusted with a balance adjusting trimmer. An instrument is separately needed to
check the ion balance.

3. DC mode
Plasma ions or minus ions are continuously discharged. The parts other than the charged object need to
be grounded to prevent them from being charged. The plasma and minus ions cannot be discharged
simultaneously.
3-2. Detection of the dirt on the electrode needle
When the maintenance start-up signal is input, the ionizer detects if the static charge elimination
capability is degraded due to the dirt on the electrode needle. If the electrode needle needs to be cleaned
because of the degraded capability of the static charge, the maintenance LED lights up, and then the
maintenance output signal is output. Because just installing the feed back sensor or auto balance sensor is
not enough to detect if the static charge eliminating capability is degraded, regularly input the maintenance
start-up signal to check the static charge elimination capability.

1. Selection of the bar length
・Select an appropriate length that is suitable for the work size, static charge elimination characteristics
and static charge elimination range.
2. Installation of the ionizer
・Keep the distance between the ionizer and charged object within 50 to 2000mm. When the auto
balance sensor is used, the distance should be ranged from 100 to 2000mm. When the ionizer is used
outside of the operating conditions, it might not operate properly. In that case, be sure to check if the
ionizer will operate properly.
3. Installation of the sensor
・Install the auto balance sensor to adjust the ion balance.
・Horizontally place the auto balance sensor under the ionizer, and install the sensor on the same level
with a workpiece as much as possible.
・When he auto balance sensor is connected, the balance adjustment trimmer will be invalid.
4. Setting of the maintenance level selecting switch
・[manual operation] or [auto operation] can be selected when the ion balance needs to be adjusted with
the auto balance sensor.
Description

operation
Ion balance is adjusted when the maintenance MANUAL
start-up signal is input or when the power
supply of the Ionizer is applied.
The ion-balance adjustment values are
retained per ion-production frequency. When
the ion-production frequency is changed, adjust
the ion balance.
AUTO MANUAL
Once the ion-balance adjustment is completed,
the ion balance adjustment will not be executed
unless the next maintenance start-up signal is
input. Therefore, the auto balance sensor can
be removed.
Auto operation Ion-balance is continuously adjusted.
Once the auto balance sensor is removed,
manually adjust the ion-balance with a balance
adjustment trimmer.
AUTO
* Set the switch in line with the detection level of the dirt on the electrode needle.
・When the auto balance sensor is not used, change the switch setting to AUTO, and manually adjust the
ion-balance with a balance adjustment trimmer.

・Set the level for detecting the dirt on the electrode needle.
・Select the level from H（High）, M（Middle） or L（Low）. The dirt on the electrode needle cannot be
detected with other levels.
H（High） ・・・ The level that doesn’t affect the static charge eliminating time (Even a small amount of
dirt can be detected).
M（Middle） ・・The level that can notify the maintenance just before the static charge elimination time becomes
slow.
L（Low） ・・・ The level that the static charge elimination time becomes slower than the one in the initial state.
・The dirt detection will begin once the maintenance start-up signal is input.
・If H, M and L levels are set, ion balance adjustment is executed after the dirt on the electrode needle is
detected.
