  • When using as a CSA and UL compliant product, use a CLASS 2 CSA/UL certified power supply, or a CSA/UL certified power supply that has been evaluated as a Limited Power Source as specified in CAN/CSA-C22.2NO.60950-1/UL60950-1.

• This product has been developed / produced for industrial use only.

• 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 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.

• Do not use this product in steamy or dusty places and in places where water splashes or spatter flies when welding.

• Avoid use at an elevation higher than 2000m, and outdoor use.

• 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.

• Do not turn the power back on immediately after it has been turned off,wait at least 1 seconds before turning the power back 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.

• After connecting the cables,check that the connections are correct before turning on the power. If the cables are connected incorrectly,operating problems or accidents may occur.

• 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.)

• Extension up to total 10m is possible with 0.15mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

• When this product is no longer usable or required, carry out the appropriate disposal process meant for industrial waste.

MOUNTING

• When this product is mounted onto a surface, use M4 pan-head screw (please arrange it separately). The tightening torque should be 0.5N･m or less.
• Be sure to ground the F.G. terminal. If the grounding is not proper, the charge removal capability deteriorates considerably. (Direct earth or power supply common earth)
• The power supply of common earth can also be connected with the accessory lead wire for F.G.connection.
  • 0V earth: Connect No. 2 and No. 3 of the end connector (9-way) with the lead wire for F.G. connection.
  • +V earth: Connect No. 1 and No. 3 of the end connector (9-way) with the lead wire for F.G. connection.
• The wrong wiring of the grounding causes an accident or malfunction. Check the grounding condition to be used beforehand and take care not to short-circuit the power supply when wiring.
• If an AC adapter is used, be sure to connect the F.G. terminal to the power supply common earth. For details of wiring, refer to the instruction manual enclosed with the AC adapter for the ER-VW series (ER-VAPS1-W).

ALIGNMENT OF BLOWING AIR

• Screwing the nozzle down.
• Aim the nozzle to the object being charged.
• After aligning, tighten the nozzle by hand till it touches the main body and confirm that the nozzle doesn’t move.
• If the nozzle is not tightened enough, the charge removal capability may deteriorate or the nozzle may drop.
• The adjustable range of the nozzle is shown in the right figure.

PIPING

• The air tube to be attached to the air inlet of this product should be the outer diameter φ6mm / internal diameterφ4mm.
• Supply dried clean air to this product. (Air dryer: dew point -20℃ equivalent, Air filter: mesh size 0.01μm 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-controller or mini-filter 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 airflow

CONNECTION

Take care that when using the products in series connection, the applied air pressuredrops 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･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.

INPUT SIGNAL CONDITIONS

Conditions for the discharge halt input and the reset input are as follows

Discharge halt input

Reset input

Note: Repeat control with ‘DSC OFF’ input should be 1Hz or less. Note that the continuous discharge for 2 sec. or more is required for stable detection of check output. (CHECK). In case of using with the continuous discharge for less than 2 sec. again and again, confirm the check output (CHECK) with the continuous discharge for 2 sec. or more when maintenance is carried out.

OPERATION MATRIX

Notes:

• 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 stopped 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 same.

MAINTENANCE

WARNING

• Make sure to turn off the applying air and the power supply while inspection, cleaning or maintenance is carried out.
• Before loosening the nozzles for maintenance etc., be sure to stop applying air. Otherwise, the discharge needle unit may be flew by the air pressure
• If dirt, such as dust, etc., is stuck on and around the discharge needle or inside the nozzle depending on the environment of use, the charge removal effect deteriorates. Clean those areas periodically, as a reference, once a week.
• However, when using this product in the environment exposed to too much dust, be sure to clean up the discharge needle frequently.
• 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 the needle is replaced, replace the discharge needle unit (optional).

Procedure for cleaning and replacing the discharge needle nit

1. Unscrew the discharge needle counterclockwise. Remove dirt on and around the discharge needle, inside the nozzle and inside the tube fit in the nozzle with a cotton bud soaked in alcohol. Particularly, clean the tube fit inside the nozzle and around the discharge needle thoroughly such that any dirt or grease doesn’t remain there (refer to the right figure), or the charge removal capability may deteriorate.
2. Remove/fit the discharge needle along the guide groove on the air outlet of the main body.
3. After cleaning, screw the nozzle clockwise. Tighten the nozzle by hand till it stops and then confirm that the nozzle doesn’t move. If the nozzle is not tightened enough, the charge removal capability may deteriorate or the nozzle may come off.
