Do not use air containing foreign particles, such as, carbon dust or dust, wa­ter or oil. Since those may cause electric shock or malfunction, take appropri­ate measures, such as, installing an air-filter or an air-drier, etc.
When maintenance, checkup or cleaning are carried out, make sure to cut
the air supply completely and confirm that the inside the product and the
tubes became atmospheric pressure in advance. The remained air pressure
may cause accident or malfunction.
Do not use this product for a purpose other than charge removal.
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 10m.
When this product is no longer usable or required, carry out the appropriate
disposal process meant for industrial waste.

Thank you very much for using SUNX products. Please read this Instruction
Manual carefully and thoroughly for the correct and optimum use of this product.
Kindly keep this manual in a convenient place for quick reference.

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.
Since the tip of the discharge needle is pointed, take sufficient
care in handling the discharge needle, or injuries may result.
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.

This product is a compact, corona discharge type electrostatic charge re­moval device.
This product neutralizes electrostatic charge from charged objects quickly
and effectively.
This product removes dust stuck to charged objects due to static electricity,
and keeps such objects free from electrostatic dust.

Do not use this product beyond its rated specifications. Doing so can cause
product breakdown, non-function, or damage. Further, it will also cause a
marked reduction in product life.
Never disassemble, repair, modify, or misuse this product, as it can cause
accident or malfunction.
Do not throw this product in fire. There is a danger of it exploding, or gener­ating poisonous gas.
Since this product emits ozone into the atmosphere, circulate the air if it is
foul-smelling. If ozone stays for long period, metals etc. may oxidize/decay.
Further, do not try to confirm the foul-smelling ozone by drawing your face
near the nozzle outlet. There is a danger of hurting your nose, throat, etc.
If this product is used immediately after storage in a high-humidity environ­ment, its ion balance may remain lost. Therefore, before use, leave this
product in the atmosphere with a temperature of +25 or so and a relative
humidity of 30% RH for over 8 hours.
Do not use this product in steamy or dusty places and in places where water
splashes or spatter flies when welding.
Make sure that the power supply is off while wiring and inspection. Other­wise, there is a danger of accident, electric shock or malfunction.
After wiring, reconfirm the wiring connections before switching on the power
supply.
Take care that wrong wiring will damage the product.
Verify that the supply voltage variation is within the rating.
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 (dried clean air) for the fluid. Fluid other than air (dried clean air) or
that containing corrosive gas may cause accident or malfunction.

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 get damaged due to short-circuit.
If the air supplied to this product is ON/OFF by a solenoid valve etc., turn the main
power on/off simultaneously. [Discharge halt (DSC OFF) input should be used]
If corona discharge is done without supplying air, the amount of ozone gen­eration increases remarkably.
Do not use during the initial transient time (0.5 sec.) after the power supply
is switched on.
If the power supply is switched on immediately after being switched off, fault
output may be generated. After the power supply is switched off, keep an
interval of 1 sec. or more, before switching it on again.

A typical sample (measured on a sample left in the atmosphere at a relative humidity of 65%
RH for 24 hours) applied with a power voltage of 24V, a distance of 100mm from the front
surface of the airflow inlet and a pressure of 0.25MPa while the shower nozzle is in use.
A typical sample applied with a power voltage of 24V, a distance of 300mm from the front
surface of the air flow inlet and a pressure of 0.25MPa while the shower nozzle is in use.
The air is dried (dew point: equivalent of -20) and filtered (mesh-size: equivalent of 0.01Ǵm) air.
The applicable pressure range depends on the nozzle to be used.
When the power is ON, or the discharge halt input is activated, the check output may
operate transitively, however, the charge removal capability remains the same.
In case of using the check output to halt the device or give an alarm etc., use a sequence
controller that processes with 5 sec., or more, output.
"DSC" stands for "DISCHARGE".

When this product is mounted on a housing,
use M4 screws. (please arrange separately.)
The tightening torque should be 2N㨯m or less.
If more than 2 units are mounted closely, keep
5mm, or more, distance between them. Other­wise, the capability may be affected.
Make sure to ground this product. If the
grounding is not proper, the charge removal
capability is reduced. (Direct earth or power
supply common earth)
If AC adopter is used, be sure to connect the
ground terminal to the power supply common
earth.

The outer diameter of the air-tube to fit to the air inlet portion of this product
should be Ǿ6mm.
Make sure that clean air (air containing no-water, no-oil and no dust) should
be supplied.
Since the pressure will drop when the air piping from the main pressure sup­ply is extended or pneumatic-components (e.g., needle valve, spin core, mini
filter) are added, keep an eye on the pressure supply to the ionizer making
sure it isn't in short supply. For the pneumatic- components, select those that
can accommodate the air supply flow rate.

'DSC OFF' input in the 'ERROR' state is invalid (since the 'ERROR' state is prioritized).
'RESET' input is enabled even when in the 'DSC OFF' input state, and 'DSC 'OFF' input
remains unaffected by 'RESET' input.
'RESET' input in the 'ERROR' state resumes the 'ERROR' state unless the cause of the
error has been eliminated.

٨

Since the removal discharge effect will deteriorate if dirt is stuck to the tip of
the discharge needle, clean the discharge needle periodically.
The maintenance required depends on the environment of use. As a refer­ence, the maintenance should be done once in two weeks.
The discharge needle is a part having a product life time. It is recommended
that the needle should be replaced, as a reference, after 10,000 hours in
use. When replacing it, replace the whole unit.

Ԙ
ԙ

Ԛ

ԛ

Confirm that the power supply is off.
Unscrew the discharge needle counter­clockwise.
Remove the dirt on and around the dis­charge needle with a cotton bud soaked in
alcohol.
After cleaning, screw the needle clockwise to fit. The tightening torque
should be 0.3N㨯m or less.
