2. Overview

ION WIPER Separate Type is an out-of-box static eliminator/particle removing apparatus to remove particles adhered on the workpiece

(charged material).

Ionized air coming out from the ionizer built into the blow unit neutralizes the static electricity on the charged material.

At the same time, the air blow from the blow nozzle blows out the particles on the material.

In addition, the dust collecting unit collects dusts and the filter catches the dust, exhausting from the rear of the project.

A unit type product for flexible installation to a device and a process and a box type product for installi ng on a workbench are available.

Verify that all the contents below are included in the package. If any item is missing, please contact your dealer (distributor) or a nearest

5. Operation

51. Operation procedures

(1) Ensure the power connection, grounding, air piping, wiring, and exhaust ventilation (dust collecting unit/duct piping).

(Working pressure range: 0.2 - 0.7 MPa)

(2) Open the valve source of the air device (installed by the customer) and adjust the throttle valve for the ionized air regulator/air

blow.

Adjust the ionizer supply air pressure to be withi n a range of 0.05 - 0.5 MPa. When turning on this device, always input the

air.

(Ionized air regulator)

Rotate the regulator handle with the handle securely pulled out. Rotate clockwise to increase the pressure, and rotate counter-

clockwise to decrease the pressure.

After the adjustment completes, push the handle to lock it.

Check the pressure with the pressure gauge at the front of the blow unit. (Setting range: 0.05 - 0.5 MPa)

(Throttle valve for air blow)

Rotate the throttle valve needle from the fully open position to the counter-clockwise direction to increase the blow flow rate.

When the desired flow rate is achieved, always fasten the locknut to secure the setting.

When the needle is rotated too much (the flow rate is too high), rotate the handle clockwise to decrease the flow rate.

(3) Set the blow time and blow intermittent frequency using the blow time switch TIME/blow intermittent frequency switch FREQ.

For the blow time, either use the timer setting (0.5 - 10.0 seconds) or select the blow time switch No. from the continuous setting.

When the timer setting is used (blow time setting switch No.0 - A), the product blows the air for the configured time.

When the continuous setting is used (blow time setting switch No. B - F), the product blows the air when the photoelectronic sensor

detects the workpiece.

For the continuous setting, the sensor OFF delay time can also be selected. When removi ng particles manually, for example, the

products keeps blowing the air during the OFF delay time if the target workpiece is out of the range of the photoelectronic sensor. If

the workpiece is detected again during the OFF delay time, the OFF delay time is reset.

When the blow intermittent frequency setting is used, the product provides intermittent blow at the frequency specified by the blow

intermittent frequency switch No.

Set the switch No. to "0" to disable intermittent blow.

The blow intermittent frequency switch No.8/No.9 are the user area that allows the customer to set desired behaviors.

There are two areas. The blow time/intermittent frequency/operation interval time can be configured according to the user

environment.

For details, refer to Section 6-3-4. (Setting via communication is required.)

Note: The intermittent operation is available for air blow only. Intermittent blow is not available for the ionized air.

(4) Press the "-" side of the power switch to turn on the device. The device turns on. If the power LED (green) and the

photoelectronic sensor are equipped, ensure that the power LED (green) of the photoelectronic sensor is turned on before

entering the workpiece.

The photoelectronic sensor detects the entered workpiece and the device starts the operation.

(5) The blow operation is performed with the blow time/blow intermittent frequency set in Step (3), and then the operation stops.

This is the end of the static charge/particle removal process.

Note: When adjusting the nozzle angle using the nozzle joint, if the air flow nozzle is directed to the ionized air nozzle, the static charge

removal performance may be affected.

Use the product with the air blow nozzle facing the vertical direction or the opposite direction of the ionized air nozzle.

Static charge removal performance may be affected if the ionized air pressure (set value of the ionized air regulator) is low

compared to the air blow pressure (impressed pressure).

52. LED Indicators

These indicators (turned on/flash/turned off) indicate the status of the blow unit and the additional parts.

For the details, refer to the LED status table.

(LED status table)

*1) To enable maintenance, enable the piano dip switch SW1/2 on the front of the blow unit.

(Refer to "7. Maintenance and Precautions" for details)

(Initial value) Ionizer discharge time: 300 [time]/frequency of air blow valve ON/OFF: 10 million times

Note: While the ion wiper is in operation, ensure that air is supplied to the equipped ionizer.

If the pressure setting of the ionized air regulator is less than 0.05 MPa, the device and the environment would receive harmful

effect.

Note: The particle removal effect by the ion wiper varies depending on the shape and the amount of charge of the workpiece (charged

material), air pressure, blow time, and blow intermittent frequency.

When this device is used, configure the ionized air pressure, blow flow rate/time/frequency appropriate to the workpiece.

Note: Value of the dust sensor is just a guide. It does not guarantee removal of dust from the workpiece.
