Page 10: Discharging Needle Maintenance Period (Rough Guidelines)
The photographs below show the accumulation of dust on the tip of the discharging needle used in the steady flow fan type. Depending on the application conditions, perform the cleaning after 300 to 500 hours of use. When cleaning the discharging needle, cleaning the louver and the inside of the ionizer body at the same time is recommended. 100 h... -
Page 11: Cleaning Procedure For Discharging Needle
・ The discharging needle is a consumable part that must be replaced if used over long periods. For replacement, use a dedicated tool (DTRY-ELB21). ・ After cleaning, flush the needle. Activating the ionizer with residual alcohol on the needle could result in unstable performance. The ionizer requires periodic maintenance and checks. -

Page 14: Static Electricity Q&A
Static Electricity Q&A What is static electricity? Dynamic electricity Static electricity (regular electricity) (electricity stored on materials) Static electricity is generated by clothing or seat friction. Discharges when metal is touched. Electric current When friction between materials causes the plus-minus balance to collapse and to tilt electrically toward one polarity, this condition is called static electricity. - Page 15 What types of electrification are there? Electrification is due to contact: Electrification is induced when two objects come into contact. ● Triboelectric electrification Static electricity induced when the surfaces of two objects in contact rub against each other. ● Peeling electrification ...
- Page 16 What is the difference between a conductor and an insulator? Electrification acts differently between a conductor and an insulator. Conductor: Materials that conduct electricity easily → Iron, copper, aluminum, carbon, etc. Conductor image Since electrons move freely through the c o n d u c t o r, g r o u n d i n g t h e c h a r g e d conductor results in 0V.
- Page 17 What kind of phenomenon is electrostatic induction? Bringing a charged body close to a conductor (metal, etc.) causes a build-up in the opposite charge in regions near the charged body, and a build-up of the same charge in regions farther away. This is called electrostatic induction.
- Page 18 Is there an example of work-related trouble with electrostatic induction? Even if a workpiece has no charge, bringing a charged body close to a conductor can cause polarization within the conductor due to electrostatic induction, resulting in a discharge. Semiconductor (example of device) Charged body Approaches Discharge...
- Page 19 What is electrostatic damage? With increasingly compact parts and greater semiconductor densities, electrostatic damage to circuits and devices due to electrostatic discharge (ESD) has become a major problem. In general, MOS-configuration ICs and field-effect transistors (FETs), high-frequency devices, and other similar types of equipment are extremely sensitive to static electricity, and easily susceptible to be damaged.

- Page 22 Corona discharge occurs when high voltage is locally generated between two conductors, causing a breakdown in air insulation and generating blue-violet light. In a corona discharge ionizer, high voltage is applied to the discharging needle to generate the corona discharge.
- Page 23 What is the difference between the AC and DC methods? The corona discharge type ionizer can be broadly divided into AC and DC methods, depending on the method of applying voltage. AC method : Generates positive and negative ions in alternating...
- Page 24 This causes ions within the tube to be extinguished, making carrying ions through the tube impossible. The Koganei ionizer, on the other hand, uses a high frequency of...
- Page 25 Please explain about static charge removing time and ion balance. Static charge removing time (elimination speed) and ion balance are two measures for evaluating ionizer performance. Static charge removing time The time required for objects charged to ±1000V to decay down to ±100V.
- Page 26 Low-frequency ionizer High-frequency ionizer Long cycle for Short cycle for generation of positive generation of positive and negative ions and negative ions Situation on workpiece surface when ionizer is used Large voltage Small voltage fluctuation fluctuation Apparent ion balance...
- Page 27 The situation when the plastic panel is lifted away from the metal plate is shown in Figure 2. When the plastic panel is separated from the metal plate, its potential rises sharply. If an ionizer was being used to perform efficient static charge removal, where the static charge is being eliminated is the key point.
- Page 28 When eliminating charges of a large charged object When the targeted workpiece is large in size, and the ionizer must be set at a cer tain distance away, the fan type s h o w s b e t t e r c h a r g e e l i m i n a t i o n effectiveness than the blow type.
- Page 29 9-10.) Discharging Needle Contamination The tip of the discharging needle used in the ionizer can become dirty after repeated use. If this discharging needle contamination becomes severe enough, the amount of ions generated will deteriorate, resulting in reduced static charge elimination capability. It can also lead to poor ion balance.
- Page 30 Please explain the measurement principles for the electrostatic potential sensor EP Sensor. The electrostatic potential sensor EP Sensor uses the electrostatic induction phenomenon that arises between the charged body and detection electrodes. The electric field from the charged body generates an induction charge in the detection electrode surface. This induction charge is then calculated and displayed as the potential of the charged body.

Page 31: Frequently Asked Questions
It does not serve to extend the operating life of the ionizer itself. Can the ionizer be used in explosive atmospheres? Corona discharges are induced when ions are generated, and since it could ignite in a flammable gas atmosphere, the ionizer cannot be used in such locations. - Page 32 DTRY-ELB nozzle for connecting to the main body. Please purchase the nozzle specially made for each model. What is the nozzle made of? The connection part (cone-shaped part) to the ionizer main body is made of aluminum alloy, while the tips are made of stainless steel.
- Page 33 There is no reset function for abnormal output in the EP EP sensor? sensor. A sensor abnormality is treated as a malfunction, and should be either repaired (consult with Koganei) or replaced with a new sensor. In what sort of situations do sensor abnormalities occur? When the sensor (detector) stops transmitting, this is output as a sensor abnormality.
- Page 34 Can calibration be performed? Since the CC monitor is not a measuring instrument, calibration cannot be performed. However, Koganei is ready to perform inspections and adjustments at customer request. Customers desiring this service are requested to consult with Koganei.
