Electric Wiring/Air Piping
Connect the main unit and the AC adaptor according to the wiring diagram below.
(Power supply)
· Connect the AC adapter connector to the power cable of the main unit.
Insert the connector covers into each other so no dust gets inside.
· Connect the ground cable (green wire).
Note) 0V (AC adapter output) and F.G. (frame ground wire) are connected inside the main unit.
Static charge removal performance is reduced when not fully grounded.
· Connect the AC adapter to the power supply (AC 100 V - 240 V, 50/60 Hz).
· When using the relay cable, connect it between the AC adapter connector and the power cable of
the main unit.
Note) The AC adapter cable is not a flex resistant cable.
If there is a risk of the cable moving, then secure the AC adapter cable or the connectors.
The main unit cables and relay cable are flex resistant.
The cable bending radius must be 32 mm or above.
(Air)
· Use clean air, from which oil and moisture have been removed, as the medium.
· Attach the air tube (φ6-mm outer diameter) to the air fitting on the main unit.
(Urethane tube recommended: Urethane tube/nylon tube)
Note)
The air tube length must be 3m or shorter.
· Install a regulator between the air tube and the air source.
· Do not excessively bend or twist the Φ6mm air tube near the fitting. Doing so may result in air
leakage. When using nylon tubes, the minimum bending radius is 30mm.
6. Operations
WARNING
● When using the product, do not point the nozzle at people, especially their face or eyes, etc. This
could result in personal injury.
● Use protective glasses and ear plugs because there is a risk of noise causing hearing
impairment or debris being blown into your eyes.
CAUTION
● Do not drop or hit the air gun because there are piezoelectric ceramics inside it.
● The nozzle on the tip of the main unit is connected to internal circuits, so do not let it touch live
wires or conductors.
● Use only the specified nozzle. Do not modify the nozzle. Otherwise, the product could break
down, its functions could stop, or it could be damaged.
● If the power/discharge indicator LED (green) does not light or if the error indicator LED (red)
lights, immediately turn off the power and refer to “5. Wiring and piping for installation” in this
document. If the issue cannot be resolved, refer to “7. Maintenance” and “8. Troubleshooting” in
this document.
Operations
①
Check the electric wiring and air piping.
②
Supply air that is being regulated by a regulator to the main unit. Be sure to set the pressure being
applied to within the operating pressure range.
③
Supply power (AC 100 V - 240 V, 50/60 Hz) to the AC adapter.
④
Hold the main unit firmly, point the nozzle at the workpiece, and then squeeze the lever.
Note)
Do not grip the upper part of the main body, since it may effect on the ion balance.
The power/discharge indicator LED (green) lights and ionized air sprays from the tip of the nozzle.
To stop the ionized air, release your grip on the lever. The lever returns to its original position, the
power/discharge indicator LED goes out, and the ionized air stops.

You can adjust the pulse frequency by turning the adjustment trimmer on the side of the main unit.
Use a precision flathead screwdriver to adjust it.
When using supported models: DTY-ELG31-PAU/DTY-ZPA-G31
(counterclockwise): Frequency increases.
Toward - (clockwise): Frequency decreases.
Note) Squeeze the lever in a single motion.
A pulse blow may not occur if you squeeze it slowly.
Note) The trimmer increases frequency when turned counterclockwise and decreases when turned clockwise.
The component parts of the trimmer may be damaged if you fully open or fully close it and then turn it further.
Note) Piping conditions may cause variations in frequency characteristics and flow rate characteristics.
Use a Φ6 air tube that is less than 3 m long.
Replacing the in port/pulse blow unit
Example) Replacing an in port (DTY-ZNP-G31) with a pulse blow unit (DTY-ZPA-G31)
*Use the same procedure to replace the pulse blow unit with an in port.
①
Remove the screws on the side of the main unit. To remove the cover, lift it in the direction of the arrow.
②
Lift the in port in the direction of arrow 1 to remove it in the direction of arrow 2 from the semi-circle area.
③
Align the protruding tip of the pulse blow unit with the insertion hole on the main unit, and press it in,
in the direction of arrow 3.
While pressing in, press down in the direction of arrow 4, and put it into the semi-circle area.
④
Confirm that it is fully in the semi-circle, and then close the cover.
If you cannot close the cover at this point, the pulse blow unit may not be inside the semi-circle, so
put it in again.
Fasten the cover with the screw.
(The main unit may be damaged if the correct tightening torque of 15 to 20 N
･
cm is not used.)
Note) If you changed from the pulse blow unit to the in port, then put the label provided on the pulse
blow adjustment trimmer, which is on the side of the main unit.
If you changed from the in port to the pulse blow unit, then remove the label that is covering the
frequency adjustment hole to use it.
7. Maintenance
WARNING
● Always turn off the air and the power before doing maintenance work. This can lead to malfunction
or accident.
● The tip of the discharge needle is sharp, so be careful when removing and cleaning it.
CAUTION
● Fully ventilate the area when using alcohol, etc. Also, after cleaning with alcohol, allow the main
unit to fully dry, and check that it is not wet.
● Never use a wire brush to clean the main unit, doing so could damage it.
● When installing a nozzle, tighten it by hand until there is no looseness. Do not overtighten it. Also,
do not use any tools to tighten it.
Dirt sticking to the discharge needle reduces the static charge removal performance.
Clean it periodically, or when the static charge removal performance is low.
Cleaning method
Rotate the nozzle to remove it from the main unit, then use a cloth or cotton swab dampened with
alcohol (IPA) to clean the discharge needle (tip) and surrounding area inside the main unit. Allow it to
dry completely, and then securely install the nozzle.
How to replace the discharge needle
The discharge needle is a consumable part that needs to be replaced. When replacing the discharge
needle (5 piece set: DTRY-ZEM-G31), always use a combination of the specialized tool (DTRY-
ELB21) and a torque screwdriver, and set the tightening torque to 15 to 20 N•cm for the
replacement. If the torque is not appropriate, the screw in the main unit may be damaged.
