WARNING

OUTLINE

This product is a corona discharge type electrostatic charge removal device.

The nozzle angle adjustable structure enables aligning the ionized air to desired area.

The check function which a considerable abrasion or dirt on the discharge needle is notified via the output signal and the indicator is incorporated.

The air monitor function detects whether the air is supplied to this product or not. When the air is not supplied, a corona discharge is stopped.

CAUTIONS

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.

Do not use this product beyond its rated specifications. Doing so can cause product breakdown or damage. Furthermore, it may also cause a considerable 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 foulsmelling. 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.

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.

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, keep an interval of 1 sec. or more, 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 (dried clean air) for the fluid. Fluid other than air (dried clean air) or that containing corrosive gas may cause accident or malfunction.

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.

Do not use this product for a purpose other than charge removal.

Do not block the air blowing outlet. Ozone is filled in the air, causing accident or malfunction. (The air monitoring function detects by a falling of the applied air pressure. Thus, if the air blowing outlet is blocked, the discharge is not halted by detection. ) 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 dis-

posal process meant for industrial waste.

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.

When loosening the nozzles for aligning the blowing air or maintenance, be sure to stop applying air. Otherwise, the discharge needle may be flu out by air pressure. Furthermore, after the work, screw up the nozzles by hand till they touch the main body. Insufficient tightening may affect the charge removal capability or drop the nozzles.

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

PIPING

The air tube to be attached to the air inlet of this product should be the outer diameter Ǿ6mm / internal diameterǾ4mm.

Supply dried clean air to this product. (Air dryer: dew point -20 equivalent, Air filter: mesh size 0.01Ǵm equivalent)

Since air pressure drops depending on the length of the air tube from the air supply source or adding the pneumatic equipments (needle valve, speed-controler or minifilter etc.), take care that the air pressure of the supplied air to the product is maintained. (The applied pressure should be checked around the air inlet of each unit.) Furthermore, choose the appropriate pneumatic equipments in terms of air flow.

CONNECTION

Take care that when using the products in series connection, the applied air pressure drops gradually unit by unit. (The volume of the drop depends on the connected tube length.)

Use the optional series connection set (ER-VWAR80) for series connection (One set per unit is required). The maximum No. of the connectable units is 5 (Including this unit). When using the units in series connection, fit the end connector on the connector for series connection of the unit connected to the end. Even if only one unit is used, fit the end connector on the connector for series connection.

Fit the air inlet fitting (enclosed with the series connection set) after taking the sealing cap off with a hexagonal wrench. The tightening torque should be 0.5N㨯m or less. Note that the gasket is fit in the air inlet. Be sure to tighten the fitting with the gasket.

When using the units in series connection, make sure that the air pressure around the air inlet of each unit is appropriate.

The air monitor function is to monitor the supplied air pressure. If the air pressure falls less than 0.02MPa approx., the discharge from the needle stops and the indicator lights up. If the air pressure rises again after the pressure fall was detected, discharge starts again. The air monitor function always check the air pressure and independent from the other functions (ERROR, CHECK or the discharge halt input). Thus, even in the state that the discharge was ped by another function, if the air pressure falls, the air monitor indicator (orange) lights up. In the state that the discharge from the needle stops, such as when the air pressure fall is detected or while the discharge halt input is input etc., CHECK and ERROR detection function do not operate. The discharge halt input is invalid in error state. CHECK function doesn't operate as well. When the discharge from the needle stops due to the air monitor function, the discharge halt input or ERROR detection function, the detection result by CHECK function is erased. The detection is carried out again when the discharge from the needle restarts. Remove the cause of error, and then reset the unit. In case the cause of error has not been removed, the unit goes into the error state again. In order to reset the unit in error state, turn the power off and on again. In case the discharge from the needle is controlled in the state that air is supplied, CHECK may be output temporarily due to a transitional state of the discharge phenomenon. However, the charge removal capability remains the
