Selectable charge removal layout
Nozzle angle adjustment and joint layout can be selected as desired
Nozzle angle adjustment mechanism
The angles of the two nozzles can be adjusted within a range of approximately 190° by screwing down the ends of
the nozzles. After adjusting the angle, turn the ends of the nozzles to tighten them and secure them at that angle.
This allows the nozzle angles of the ER-VW to be adjusted easily after installation.

A high-frequency 68,000
Hz AC corona discharge
is used, so that (+) ions
and (–) ions are emitted in
rapid alternation. Because
there are none of the
sudden ion discharges
that occur with other types,
there is no tendency to
partial oppositely-charging
even when charge removal

localized charges, so that
any damage to electronic
devices can be avoided.

Produces excellent ion balance
The adoption of high-frequency AC method allows
extremely stable ion balance to be achieved. The ion
balance is not affected by the pressure of air supplied
and the setup distance, so no troublesome adjustments
are required after setup.
High-frequency 68,000 Hz AC method provides
the highest level of charge removal performance
In contrast to previous
low-frequency types and DC
types, the high-frequency AC type
generates (+) ions and (–) ions
more efficiently and thus it creates
a stable environment with high ion
density. This means that a stable
ion balance and excellent charge
removal performance can be
provided regardless of the setting
distance.

FUNCTIONS
New concept
The functions support accurate charge removal
This function causes discharging to stop automatically if the
supply of air drops below a certain pressure. Notification of
this is given when the AIR indicator lights and the discharge
output (DSC) turns off. This prevents objects which are not
charged from being overlooked when the air supply has
been stopped.
In addition to the air supply monitoring function, the ER-VW
is equipped with the following functions to ensure accurate
charge removal.

•Discharge halt function: Uses external input to forcibly stop discharge.
•Check function : Uses the CHECK indicator and output to notify the
operator when it is time to clean or replace the
discharge needle.
•Abnormal discharge: Uses the ERROR indicator and output to notify the
monitoring function operator when a problem with discharge occurs,
and stops discharge. It can be canceled by means
of reset input.
•Discharge output : Output is ON during discharging. This lets you
check when discharging is being carried out.
•Check output : Output turns ON when the discharge needle is dirty.
•Error output
: Output turns OFF when there is a problem with
discharging (normally it is ON). It also allows you to
check the power supply to the ionizer.

PRECAUTIONS FOR PROPER USE
• This product is to remove static electricity
for industrial use. Never use this product for
medical equipment etc. relating to maintenance /
supervision of human life or body, for prevention
of accidents which damage a human life or
properties, or for safety maintenance.
• Do not use this product near or around
surroundings containing any dangerous
materials, such as combustible material and
flammable material.
• The discharge needle gathers dust after
a long period of use. In order to prevent
accident or product malfunction, clean up the
discharge needle, periodically once every two
weeks or so, or this product will be unable to
exert the charge removal performance.
• Be sure to ground the main body of this
product via ground terminal to ensure electric
shock prevention and reliable charge removal.
• Since the discharge needle is live with high
voltage, never touch the discharge needle,
or an electric shock may result.
• If this product is used in an airtight room, ozone
emitted from this product may be detrimental.
Therefore, in order for this product to be
used in an airtight room, be sure to keep the
room ventilated.
• Since the ion air contains ozone, do not aim
this product at anyone.
• Always be sure to turn off the air supply before
loosening the nozzles to carry out air flow
adjustment or for maintenance. Air pressure
may cause the discharge needle to fly out.
Furthermore, push the nozzle securely in by
hand until it touches into the enclosure of the
device afterwards, and check that the nozzle
does not move. If the nozzle is not installed
correctly, it will adversely affect charge removal
performance and the nozzle may also fall out.
• Since the tip of the discharge needle is
pointed, take sufficient care in handling the
discharge needle, or injuries may result.

separately), and tighten them
at a torque of 0.5 N·m or less.
• Be sure to connect the F.G.
terminal to ground. If the unit
Nozzle
is not properly grounded,
charge removal performance
will be severely reduced. (Use a type D ground or a
common power supply ground.)
• If grounding to a common power supply ground, you can
use the lead wire for connecting the F.G. that is supplied
with the unit to make the connection.
0 V ground: Connect pins 2 and 3 of the end connector
(9-pin) to the lead wire for connecting the F.G..
+V ground: Connect pins 1 and 3 of the end connector
(9-pin) to the lead wire for connecting the F.G..
If the ground is not connected correctly, operating
problems or accidents may occur, so be sure to
check the usage conditions and connect the ground
in such a way that the power supply does not
become shorted.

Adjusting the air blowing direction
• After screw down the nozzle to loosen it, point it toward
the object to be charge removal. After adjusting the
position, securely tighten the nozzle by hand until it is
touching the enclosure, and check that the nozzle does
not move. If the nozzle is not installed correctly, it will
adversely affect charge removal performance and the
nozzle may also fall out.

Piping
• The tube that is installed to the air intake of this device
should have an outside diameter of 6 mm 0.236 in and an
inside diameter of 4 mm 0.157 in.
• The air that is supplied to this product should be dried
clean air that has been processed through an air dryer
(dew point around –20 °C –4 °F) and an air filter
(mesh size around 0.01µm 0.0004 mil).
• Increasing the length of the air hose from the air supply
equipment or adding pneumatic equipment (such as
a needle valve, governor or miniature filter) will cause
drops in the pressure of the air supplied to the device,
and so do not allow the air pressure to drop below
sufficient levels. (Check the pressure applied to the
device at the air intake of the device.)
Furthermore, select air pressure equipment that is
appropriate for the level of supplied air flow.
Connections
• Use the ER-VWAR80 joint kit (optional) to connect
the devices together. (1 kit is needed for each pair of
devices.) Up to a maximum of 5 units can be connected
together (including this unit).
When using units that are connected together in this way,
attach the supplied end connector to the connector of the
last device in the series. Furthermore, also connect the
end connector to a device if not connecting the device to
any other devices.
• The air joint (included in the joint kit) should be tightened
at a torque of 0.5 N·m or less.
• When connecting devices together, check that the air
pressure values at the air intakes of each device are
appropriate for the usage conditions.

Turn the nozzle
counterclockwise to remove it.
Discharge
Replace the discharge needle
needle unit
unit, or use a cotton swab
ER-VWANT
moistened in alcohol to clean the
Nozzle
discharge needle and the area
around it.
For the needle discharge unit while running it along the
guide at the side of the opening.
After cleaning, turn the nozzle clockwise to install it.
Securely tighten the nozzle by hand until it is touching
the enclosure, and check that the nozzle does not move.
If the nozzle is not installed correctly, it will adversely
affect charge removal performance and the nozzle may
also fall out.

• Make sure to use the DC power supply insulated by an
isolation transformer, etc. for this product.
If an auto-transformer, etc. (single winding transformer)
is used, this product or the power supply may be
damaged due to short-circuit.
• Do not use this product beyond its rated specifications.
Doing so can cause product breakdown, non-function,
or damage. Furthermore, it will also cause a marked
reduction in product life.
• Never disassemble, repair, modify, or misuse this
product, as this can cause an accident or malfunction.
• Do not throw this product into fire: it may explode or
generate poisonous gas.
• Since this product emits ozone into the atmosphere,
circulate air to prevent foul smells.
If ozone lingers for long periods, metals, etc. may oxidize /
decay. Furthermore, do not try to confirm that foul smells
are caused by the ozone by drawing your face near the
nozzle outlet and air outlet: you may hurt your nose,
throat, etc.
• Do not use this product in steamy or dusty places, in
places where water and oil splash, or where spatter flies
when welding.
Refer to p.1501 for general precautions.
• Make sure that the power supply is off while wiring and
inspection.
Otherwise, there is a danger of accident, electric shock or
malfunction.
• Do not use during the initial transient time (0.5 sec.) after
the power supply is switched on.
• Verify that the supply voltage variation is within the rating.
• If the power supply is switched on immediately after
being switched off, fault output may be generated. After
the power supply is switched off, wait at least 1 sec.
before switching it on again.
• If power is supplied from a commercial switching
regulator, ensure that the frame ground (F.G.) terminal of
the power supply is connected to an actual ground.
• In case a surge is generated in the used power supply,
connect a surge absorber to the supply and absorb the
surge.
• Do not run the wires together with high-voltage lines or
power lines or put them in the same raceway. This can
cause malfunction due to induction.
• Confirm the wiring and piping state before supplying
power or air. Wrong wiring and piping may cause
malfunction.
• Use air (dry, clean air) for the fluid. Any fluid other than
air (dry, clean air) or even air containing corrosive gas
may cause an accident or malfunction.
• Do not use air that contains foreign particles, e.g. carbon
dust, dust, water or oil.
Since these substances may cause electric shock or
malfunction, take appropriate countermeasures, e.g.
install an airfilter, air-drier, etc.
• Do not use this product for any purpose other than
charge removal.
• Do not cover the ionized air outlets of the nozzles. Ozone
may build up and operating problems or failure may
occur. (The air monitoring function checks if the pressure
of air supplied to the unit drops, so if the ionized air
outlets of the nozzles are covered, it will not detect this
and will not cause charge removal operation to stop.)
• This product is CE-conformed under the EMC Directive.
The immunity adopted by this product should be
conformable to EN 61000-6-2. In order for such immunity
to be conformable to this standard, all wires connected to
this product should be limited in length to less than 10 m
32.808 ft.
• When this product is no longer usable or required,
dispose of properly as industrial waste.
