Ultra-compact Ionizer ER-V

When this product is mounted in a housing, use M4 screws (please arrange separately). If more than 2 units are mounted close together, keep 5 mm 0.197 in or more between them. If used at distances within 5 mm 0.197 in, performance may be affected.

• Ensure sufficient space for daily check and maintenance.
• If AC adapter ER-VAPS1 is used, be sure to connect the ground terminal to the power supply common earth.
• Make sure to ground this product. If the grounding is not proper, charge removal may be impaired. (Direct earth or power supply common earth)
• If an electrostatically charged object is in contact with or near another object, charge removal may be impaired. Install this product such that ions are blown against the electrostatically charged object, when the object is at a distance from other objects or is floating in mid-air.

• There are Select the suitable model for your application.
• Appropriate air pressure for each nozzle should be used.
• To fit the air nozzle, screw it to the product till it stops.

• The outer diameter of the air tube for the air inlet of this product should be ø6 mm ø0.236 in.
• Make sure that clean air (air containing no water, no oil and no dust) should be supplied.

• The charge removal effect will deteriorate if dirt is stuck to the tip of the discharge needle. If a check signal is output, clean the discharge needle.
• Clean the discharge needle periodically even if no check signal is output.
• The discharge needle’s life-time is approximately 20,000 hours.
  Please change it after this period has elapsed. Use only discharge needle ER-VANT2 (optional).
• If a check signal is output even after the discharge needle has been cleaned, replace the discharge needle.
• If an error signal is output, it may indicate an abnormal discharge.
  Check the following points:
  [1]Make sure that the supply voltage is within the tolerance as per specifications.
  [2]Make sure that the discharge needle unit is mounted correctly on the main unit. Check the tip of the discharge needle for a chip or contamination. If the discharge needle is chipped or dirty, clean it or replace it with a new needle.
  [3]Check that no foreign materials are inside the nozzle, that the nozzle is mounted correctly and that the ionizer is set up correctly.
  [4]Make sure that the ground terminal is connected completely.
• To reset the ionizer after an error signal has been output, input a reset signal.

Procedure for cleaning

[1]Check that the power supply and the air supply are both turned off.
[2]Remove the discharge needle from the rear of the main unit.
[3]Remove the dirt on and around the discharge needle with a cotton swab soaked in alcohol.
[4]Check the discharge needle once more to make sure it is free from foreign particles such as thread scraps.
[5]After cleaning the discharge needle, mount it.

Replacing the discharge needle

[1]Check that the power supply and the air supply are both turned off.
[2]Remove the discharge needle from the rear of the main unit.
[3]After checking the there is no contamination on or around the new discharge needle, mount the nozzle.

• After wiring, reconfirm the wiring connections before switching on the power supply.
• Note, wrong wiring will damage the product.
• Verify that the supply voltage variation is within the rating.
• 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.

・	Only connect an isolated DC power supply, for example one equipped with an isolating transformer, or the optional AC adapter ER-VAPS1 to the 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 high voltage is applied to the discharge needle, keep your fingers, body, metal, e.g. wires or tools, etc., away from the needle. If you fail to keep away from the needle, electric shock or malfunction may be the result.
• This product is not explosion-proof. Do not use it in places where combustible or flammable material is present. There is a danger of catching fire.
• 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.
• 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.
• Confirm the wiring and piping state before supplying power or air. Wrong wiring and piping may cause malfunction.
• Do not use this product for any purpose other than charge removal.
• When this product is no longer usable or required, dispose of properly as industrial waste.
• If the air supplied to this product is turned ON / OFF by a solenoid valve, for example, make sure to turn the discharge halt input ON / OFF simultaneously.
• 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.

Piping

<Mounting example of ER-AF20 + ER-VS02>

• Fit the pneumatic fittings on the both sides of this product to connect to the pneumatic tube, as the figure shown above.

Notes:

Cautions

• Before the piping, make sure to sufficiently carry out internal flashing (blowing of compressed air) of the pipe. If scrap or sealing tape, generated during work, or rust, etc., gets inserted, it will cause clogging.
• Use air (dry,clean air) which does not contain water, oil, etc. Water or oil will cause clogging or reduction in performance.
• Do not use with a fluid or in an environment containing the following substances:
  • Organic solvents · Ester phosphate type hydraulic fluid
  • Sulfuric acid gas · Chlorine gas · Acids
• This product is for industrial use. Do not use it in equipment affecting human life.
• Never disassemble or modify this product.
• When disposing this product, dispose it as industrial waste.

Pressure drop

• When the mini line filter (ER-AF10/AF20) is fitted, a pressure drop occurs. Adjust the primary air pressure so that the secondary air pressure is within the air pressure range of the ionizer. (Take are that the air pressure range differs depending on the nozzle. Furthermore, in case the filter is used with the max. processed air volume, approximately 0.1 MPa of pressure drop occurs.)
• Take care that if the air more than the specified processed air volume is applied, the efficiency will deteriorate.
