1. How to Operate

1.1 Outline 1. This is equipment used to remove dust that is stuck to a workpiece due to static and to remove static

electricity and collect dust to prevent dust from sticking to the workpiece again. 2. Ionized air from IZN10E ionizer neutralizes static electricity and blows dust away from the workpiece.

1.2 Installation and Piping 1. This product must be installed on a stable horizontal surface. 2. Avoid using in a place where noise (electromagnetic wave and surge) is generated.

It may cause failure or damage to the product. Take measures to prevent noise at source and avoid power and signal lines from coming into close contact.

3. Do not allow foreign matter, workpiece or tool to enter the ionizer nozzle. There is an emitter inside the nozzle. If the emitter gets in contact with metallic workpieces or tools, electrical shock may cause injury. If emitter is damaged, it may interfere with the specified function and performance, and may also cause operation failure and accident.

4. Mounting, wiring or adjustments should never be done without shutting off the power supply to the product.

5. Make sure to confirm the effect of static elimination after installation. 6. Power supply required to the product is 24 VDC and 1A.

When power is supplied to the product without using the exclusive AC adapter, make sure to use a stabilization power supply and connect wiring to the DC plug that is provided with the product as an accessory. - Refer to P6 for wiring.

7. AC power supply cable of the exclusive AC adapter has a socket configuration that is for 100 VAC. The AC adapter is applicable to 100 to 240V. Replace it with a socket that is applicable to other voltage if necessary. The socket needs to be prepared by the user.

8. D-class ground connection (ground with a resistance of less than 100) MUST be used to the product. Without grounding, the product will not provide the designed performance.

9. Operate in an environement in the specified ambient temperature and fluid temperature ranges (0 to 55

o C).

Avoid sudden temperature changes even within specified temperature range, as it may cause condensation.

10. For air piping, use SMC tubing of diameter 8 mm or equivalent.

11. It is recommended to use supply air which purity class is 2:4:3 2:5:3 2:6:3 of ISO08573-1:2010JIS

B8392-1:2012 or higher. The air containing mist or dust will cause the performance to decrease and

shorten the maintenance cycle. Install a dryer (IDF series), air filter (AF/AFF series), and/or mist separator (AFM/AM series) to the upstream of the product to obtain clean compressed air.

12. Air connections should only be made with the pressure supply turned off. Flush the system before piping to prevent foreign matter from entering inside the product.

13. Do not allow humans or objects to touch the ionizer while power is being supplied. Otherwise, the offset voltage may change or the HV LED may turn ON.

14. Do not make a rapid pressure change while power is being supplied to the ionizer. It will cause the NDL LED to turn ON.

15. Do not use this product in an enclosed space. This product utilizes the corona discharge phenomenon. Although the amount is very small, Ozone and NOx are generated. Ozone condensation can increase if used in an enclosed space, which can affect the human body, so ventilation is necessary. Even when the room is ventilated, operating more than one product in a small space may increase the ozone density. Confirm that the ozone density in the operating environment is not more than the standard value of 0.1 ppm before starting operation.

16. When the dust collector is operating, air is discharged vigorously from the exhaust port. Prevent exhausted air from contacting people or objects. Piping (I.D. 32mm) or dust collecting bag must be connected to the exhaust port.

17. Read and understand the Operation Manual of this product before using. Confirm safety before starting operation.

Alarm name Contents How to release error

Power supply failure

When power supply which is connected to the product is not within the range of 24 V +/-10%, the abnormal signal will be turned OFF (ON when it is normal) and discharge signal will be turned OFF, and the PWR LED (green) will flash to indicate the error.

When the failure occurs, ion generation will be stopped.

To resolve the error, reset the product automatically by connecting a power supply which provides a power supply voltage of 24 V +/-10%.

Incorrect high voltage

When incorrect electric discharge is generated during operation, the abnormal signal will be turned OFF (ON when it is normal) and discharge signal will be turned OFF, and the ION/HV LED (red) will light up to indicate the error.

When the failure occurs, ion generation will be stopped.

The incorrect electric discharge could be caused by condensation or dust on the emitters.

To resolve the error, input the reset signal or supply power again after remedying the cause of the incorrect electric discharge.

CPU ALM

When CPU makes an abnormal operation due to noise or other reasons, the abnormal signal will be turned OFF (ON when it is normal), and the PWR (green), ION-HV (red) and NDL (green) LED will flash to indicate the error.

When the failure occurs, ion generation will be stopped.

To prevent noise, perform the following actions and take countermeasures.

1. Keep the product away from sources of noise.

2. Route the power line and cable of the product separately.

3. Install a noise filter to the power supply of the product.

To resolve the error, supply power again after fixing the cause of the error.

Maintenance warning

The maintenance signal is ON when static electricity neutralization performance has decreased due to contamination, wear or damage to the emitters.

The NDL LED (green) will turn ON to indicate that cleaning or replacement of the emitters needs to be performed.

The product continues operation even when the maintenance warning has been generated.

When emitters are contaminated, the error can be solved by cleaning them.

However, when they are worn out or damaged, it is necessary to replace the emitter assembly.

To resolve the error, input the discharge stop signal or supply power again after remedying the cause of the error.
