1) These products are intended for use in general factory automation equipment.

Consult SMC beforehand when using this product for other intentions. (See Warning No. 4 on page 3) 2) Use within the specified voltage and temperature range.

Operation with a voltage other than that specified can cause malfunction, damage to the product, electric shock or fire. 3) The product is not designed to be explosion proof.

Never use in an atmosphere of potential dust explosion, flammable gas or explosive gas. It may cause fire. 1) Clean specification is not available with this product. 1) Secure enough space for maintenance, inspection and wiring.

Install the product in consideration of the connector connection part and the emitter cartridge mounting part so that there is enough space for emitter maintenance, inspection and wiring. To avoid unreasonable stress applied to the connector mounting parts, bending of the cable should be more than the minimum bending radius. If the cable is bent in an acute angle or load is applied to the cable successively, it may cause malfunction, broken wire or fire.

2) Mount the product to a flat surface. Mounting on an uneven surface will apply excess force to the frame or case, which leads to damage or failure. Do not drop the product or subject it to a strong impact. This may cause an injury or accident.

3) Avoid using in a place where noise (electromagnetic wave and surge) is generated.

If the product is used in an environment where noise is generated, it may lead to deterioration or damage of the internal elements. Take measures to prevent noise at its source and avoid power and signal lines from coming into close contact.

4) Use a correct tightening torque. If the screws are tightened in excessive of the specified torque range, it may damage the mounting screws, mounting brackets, etc. If the tightening torque is insufficient, the mounting screws and brackets may become loose.

5) Do not adhere tape or sticker onto the product body. If the tape or sticker contains conductive adhesive or reflective paint, it is possible that due to the dielectric effect, charge could build up causing an electro-static discharge or electrical leakage.

6) Be sure to cut off the power supply before installing and adjusting the product. 1) Secure enough space on the rear side of the Ionizer so that the fan absorbs the air.

This product ventilates with an fan motor. If there are obstacles such as wall on the rear side (Air absorption side) of the Ionizer, the ventilation will be obstructed, decreasing the static neutralization performance. Install the Ionizer so that its rear surface is at least 20 mm (For IZF21) or 30 mm (For IZF31) away from the obstacles.

2) Make sure to confirm the effect of static neutralization after installation. The effect of the static neutralization varies depending on the surrounding installation and operating

conditions. Confirm the effect of the static neutralization after installation. 3) When installing Ionizers which operate in DC mode (one polarity, positive or negative) close together,

they should be positioned at least 2m away from each other. When an Ionizer is used close to the Ionizer which operates in DC mode, separate them by at least 2m. The

offset voltage (ion balance) may not be adjusted by the built-in sensor due to the ions discharged from the Ionizer which operates in DC mode.

3. Installation and Wiring Do not install the Ionizer in a place where static electricity or noise is generated. The effect of the static neutralization varies depending on the surrounding installation and operating conditions.

Confirm the effect of the static neutralization after installation.

3-1 Installation 3-1-1. Precautions for Installation

Be sure to cut off the power supply before installing the product. Do not adhere tape or sticker onto the product body. If the tape or sticker contains conductive adhesive or

reflective paint, it is possible that due to the dielectric effect, charge could build up causing an electro-static discharge or electrical leakage.

When installing the Ionizer, ensure the air adsorption side of the product is at least 20mm (for IZF21) or 30 mm (for IZF31) away from any walls or obstacles. If there is an obstacle such as wall on the air adsorption side of the product, the static neutralization capacity will be reduced due to ventilation resistance.

The emitter cartridge can be mounted/removed with one touch. However, it is possible to secure it with a screw as necessary. To secure the emitter cartridge with a screw, use an M3 x 0.5 12mm cross recessed round head screw (The screw needs to be prepared by the user). M3 screw recommended tightening torque is 0.25 to 0.35 Nm.

Install the ionizer so that the emitter cartridge can be removed for maintenance and replacement of the emitters.

To remove the emitters for cleaning or replacement, pull it to the air blow side while the part A of the emitter cartridge is being pressed. (If the emitter cartridge is secured with a retaining screw, remove the screw before removing the emitter cartridge.)

Do not directly touch the emitters with your finger or tools. It may prick your finger and result in injury. Also,

if the tooldamages the emitters, it may interfere with the specified function and performance, and may also cause operation failure and accident.

High voltage is applied to the emitters. Never touch the emitters. It may cause electrical

shock.

4. Function 4-1. Name of Parts

4-2. Adjustment of Offset Voltage Although the offset voltage (ion balance) of this product has been adjusted before shipping, readjustment may

be required depending on the installation environment or conditions. The adjustment can be performed using a balance adjusting trimmer which has an indication of ADJUST.

When adjusting the offset voltage (ion balance), use a measuring instrument such as charge plate monitor. As described in "4-7-2. Averaging Function", this product exchanges the polarity of voltage applied to the

emitters. After adjusting the offset voltage (ion balance), supply power again to exchange the polarity of voltage applied to the emitters. Then, adjust the offset voltage (ion balance) again after rotating the trimmer to the end and returning it. In addition, adjustment of the offset voltage (ion balance) may be required after replacing the emitter cartridge with a new one.

Rotating this balance adjusting trimmer in clockwise direction increases positive ions, and rotating it in counter-clockwise direction increases negative ions.

4-4. Emitter Dirt Detection and Cleaning If the ionizer is used for an extended period of time, contamination such as dust will stick to the emitters,

reducing the static neutralization performance. This product has a function which monitors the emitter contamination all the time. When the emitter

contamination is detected, it is indicated by the maintenance signal and LED. The emitters should be cleaned when contamination is detected, or once a week. (The cleaning frequency varies depending on the environment where the ionizer is installed.) The emitters can be cleaned manually or automatically (option). If the ionizer performance does not recover after cleaning the emitters, it can be assumed that the emitters are

damaged or worn out. If wear or damage of the emitters is detected, replace the emitter cartridge with a new one.

4-4-1. Manual Cleaning

Clean the emitters with the cleaning kit [IZS30-M2] or a cotton bud soaked in alcohol. Before cleaning the emitters, make sure that the power supply is OFF and confirm that the fan motor stops. If

the cleaning is performed before the fan motor stops, it may cause injury. In addition, if the emitters are touched while they are being energized, it may cause electrical shock or accident.

As the emitter ends are sharp, be careful not to touch them by hands. Otherwise, it may cause injury. - Replacement and cleaning of emitter cartridge -

1) Turn off the power supply of the ionizer. The fan motor rotation does not stop immediately due to inertial force even when supplying power is stopped. Confirm that it stops before moving the next step.

2) As shown in the figure below, remove the emitter cartridge by pulling it out to the air blow side while the part A of the emitter cartridge is being pressed. (If the emitter cartridge is secured with a retaining screw, remove the screw before removing the emitter cartridge.)

3) 8 emitters are mounted on the inside of the removed emitter cartridge. Clean all of them.

Using the cleaning kit, saturate the felt with industrial alcohol, insert it into the emitters and rotate several times to clean. If the dirt does not come off, use the rubber grindstone to clean the emitters in the same way. After that, again use the felt saturated with industrial alcohol to finish the cleaning.

If a cleaning kit is not available, saturate a cotton swab with alcohol to clean the emitters. The industrial alcohol used should be reagent ethanol class 1 99.5vol% or greater.

The cleaning kit has a felt pad and a rubber grindstone. Choose the felt or rubber grindstone depending on the level of contamination to effectively clean the emitters.

Felt: Use for normal cleaning. Rubber grindstone: Use if dirt is hard and stuck to the emitters and it is not possible to remove it with felt.

4) Put the emitter cartridge back in its original position by following the removal procedure in reverse.

Remount the emitter cartridge so that the terminals on the body contactwith the terminals on the emitter cartridge. Be careful that no contact failure or short circuit caused by adhesion of foreign matter occurs when connecting those terminals. Make sure that no foreign matter is adhered to the connector of the body.

The recommended tightening torque for emitter cartridge retaining screw is 0.25 to 0.35 Nm.

4-4-2. Emitter Cleaning with an Automatic Cleaning Unit (Option) Cleaning is performed by the cleaning arm mounted on the front

surface of the fan. To start the automatic cleaning, input the cleaning signal or press the

operation button. The ion generation and fan motor are stopped during automatic

cleaning. Do not stop the operation of the cleaning arm mounted between the

finger guard and the fan motor during automatic cleaning. Never stop the operation as this may cause breakage. The cleaning time is approximately 2 seconds. When performing the automatic cleaning by signal input, refer to "3-2

Wiring" and "3-3 Timing Chart". A magnetic type origin detection sensor is used for controlling the

automatic cleaning. Keep magnetic field more than 50 mT away from the ionizer enclosure. If a magnetic field more than 50 mT approaches the ionizer enclosure, the ionizer may malfunction. If the automatic cleaning stops due to power failure or other reasons,

restart the cleaning operation to put the cleaning arm back to the original position.

4-5. Replacement of Emitter Cartridge If the emitters are worn out or damaged, replace the emitter cartridge. Before replacing the emitters, make sure that the power supply is OFF and confirm that the fan motor stops.

Fan motor rotates due to inertial force even when supplying power is stopped. Confirm that the fan stops before performing repair work.

Remove the emitter cartridge by pulling it out to the air blow side while the part A of the emitter cartridge is being pressed. (If the emitter cartridge is secured with a retaining screw, remove the screw before removing the emitter cartridge.)

Remount the emitter cartridge onto the body by following the reverse procedure for removal. As the emitter cartridge and the body have terminals for confirming the connection and for applying high voltage to the emitters, remount the emitter cartridge onto the body so that those terminals contact each other. Be careful that no contact failure or short circuit caused by adhesion of foreign matter occurs when connecting those terminals. Make sure that no foreign matter is adhered to the connector of the body. The recommended tightening torque for emitter cartridge retaining screw is 0.25 to 0.35 Nm.

4-6. Alarm Function

If abnormal functioning occurs during operation of the ionizer, the user is alerted by the external output signal or LED operation.

1) Power supply failure When power supply which is connected to the ionizer is not within the range of 24 V +/-10%, the

abnormal signal will be turned OFF (ON when it is normal), and the PWR LED (green) will flash to indicate the error.

When the failure occurs, the fan motor rotation and ion generation are stopped. To resolve the error, reset the product automatically by connecting a power supply which provides a

power supply voltage of 24 V +/-10%.

2) Incorrect high voltage When incorrect electric discharge is generated during the ionizer operation, the abnormal signal will be

turned OFF (ON when it is normal), and the ION/HV LED (red) will light up to indicate the error. When the failure occurs, the fan motor rotation and ion generation are stopped. The incorrect electric discharge could be caused by condensation or dust on the emitters. To resolve

the error, input the ionizer stop signal or supply power again after remedying the cause of the incorrect electric discharge.

3) Fan motor failure

When the fan motor malfunctions during the ionizer operation, the abnormal signal will be turned OFF (ON when it is normal), and the ALM LED (red) will light up to indicate the error.

When the failure occurs, the fan motor rotation and ion generation are stopped. The fan motor failure could be caused by failure of the rotational operation due to foreign matter

entwined the fan motor. To resolve the error, input the ionizer stop signal or supply power again after removing the foreign matter.

4) CPU failure

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, ION-HV, ALM, and NDL LED (red) will flash to indicate the error.

When the failure occurs, the fan motor rotation and ion generation are stopped. To prevent noise, perform the following actions and take countermeasures.

1. Position the ionizer away from the noise source. 2. Route the power line and cable of ionizer separately. 3. Install a noise filter to the power supply of the ionizer.

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

5) Output signal over current When excessive current flows to the output circuit, the output will be blocked to protect the circuit and the

abnormal signal will be turned OFF (ON when it is normal) to indicate the error. The ionizer operates even when excessive current is generated in the output circuit. To resolve the

error, reset the product automatically by reducing the current to the output circuit down to 100 mA or less. 6) Maintenance warning

The maintenance signal is ON when contamination, wear or breakage of the emitters is detected. The NDL LED (green) will light up to indicate that cleaning or replacement of the emitters needs to be performed.

The ionizer operates even when the maintenance warning is 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 cartridge with a new one. To resolve the error, input the ionizer stop signal or supply power again after remedying the cause of the error.

7) Emitter cartridge mounting failure

When the emitter cartridge is not mounted; when power is supplied while the emitter cartridge is not being mounted onto a correct position; or when the correct emitter cartridge mounting cannot be detected due to foreign matter got caught into the terminals which detect connection of the emitter cartridge, the abnormal signal will be turned OFF (ON when it is normal), and NDL LED (red) will light up to indicate the error.

When the failure occurs, the fan motor rotation and ion generation are stopped. To solve the error, supply power again to the product after remounting the emitter cartridge onto a correct position or removing the foreign matter adhered to the terminals which detect connection of the emitter cartridge.

8) Automatic cleaning failure (for product with an automatic cleaning unit)

When the cleaning does not finish in the specified period of time, the abnormal signal will be turned OFF (ON when it is normal), the ALM LED (red) will light up, and the NDL LED (red) will flash to indicate the error.

The automatic cleaning failure could be caused by operation failure due to foreign matter entwined the cleaning parts or by malfunction of the magnetic type origin detection sensor due to environmental magnetic field. To resolve the error, supply power again after removing the foreign matter or/and magnetic field.

4-7. Offset Voltage Performance Maintaining Function This product uses corona discharge for ion generation, and DC method for voltage application.

Although the ion generation efficiency of the DC method is high, the contamination and/or wear level are different between the plus emitters and minus emitters when the product is used for a long period of time. Therefore, the offset voltage (ion balance) performance will be deteriorated quickly.

As countermeasures against the offset voltage (ion balance) performance deterioration due to contamination or/and wear of the emitters when the ionizer is used for a long period of time, this product has the following functions.

1) Ion balance sensor 2) Averaging function

4-7-1. Ion Balance Sensor IZF21 and IZF31 have a built-in sensor to maintain the offset voltage (ion balance) performance in an

appropriate condition. The built-in sensor monitors the ion generated from the ionizer with F.G. and adjusts the amount of

supply of the positive and negative ions all the time so that the offset voltage (ion balance) can be maintained in the initial condition automatically.

4-7-2. Averaging Function This product has an averaging function to control the offset voltage (ion balance) performance

deterioration caused by difference of contamination or/and wear between the emitters which generates plus ion and the emitters which generates minus ion.

To prevent the offset voltage (ion balance) performance deterioration, the applied voltage to the emitters which generates positive ions and to the emitters which generates negative ions is exchanged so that the contamination or/and wear differenence between the emitters are averaged. The voltage applied to the emitters is exchanged every time when power is supplied.

4-8. Louver (Option) By mounting a louver onto this product, the generated ions can be diffused or sent with focusing. When diffusing the generated ions, the static neutralization area can be wider in one direction by

extending the area to an oval area compared to a circular area. When the louver is mounted so that its adjuster moves horizontally, the ionized air spreads out as shown in the figure. The louver can be adjusted in five scales.

Refer to "5. Performance" for the static neutralization performance. To mount the louver, insert the four attachment features (part A) of the louver into the gaps between the

innermost ring of the finger guard and the next ring, and push it into the finger guard. The mounting direction can be changed in 90

o .

To remove the louver, insert a tool such as driver into the groove (part B), and push the hook. Be careful not to touch the emitters of the emitter cartridge when removing the louver.
