Desco SCS 966-II User Manual
Desco SCS 966-II is a high-performance air ionizer that effectively neutralizes static electricity and removes dust particles. With its compact design and easy installation, it's ideal for various industrial and commercial applications. The ionizer generates a high-frequency, high-voltage current to produce a stream of positive and negative air ions, which are then dispersed into the surrounding environment. These ions neutralize static charges on objects, preventing the attraction of dust and other particles.

3. Operation:
This IONIZER consists of the following parts: The 966-II, optional nozzles, an electrode, and a high-voltage transformer.
The ionizer displays a warning when there are abnormal conditions. It applies high-frequency-high-voltage from the highvoltage transformer to the discharge needle inside, giving off alternating current corona discharges toward the optional nozzle, and produces positive and negative air ions. It transfers the air ions through the air. The ionized air neutralizes the static of charged objects located nearby, and removes dust that is on charged objects. One benefit of this ionizer is that it can transfer ionized air by using the optional air tube, in addition to air blowing directly through the air nozzle. The nozzle can fit the main unit.

This product emits ozone into the atmosphere. Do not use this product in an enclosed space.
Equipment used around the product should have ozoneprevention measures. In addition, check regularly that nearby equipment will not be affected by exposure to ozone.
Installation:
・ Install it at a designated place by using fixing holes (3 -
φ
3.4). The 966-II does not work well in a vertical position. Please always mount it horizontal or pointing down.

Note 1: Use mechanical switch or photo coupler or relay for external input. If the grounding potential of external device to use for external input and the grounding potential of this product use are different, the external device used for external input should have an insulated on/off procedure for the 0V line.
・ Be sure to carry out the grounding procedure (according to the class D procedure).
・ Check that the Frame of the Machine is grounded. If it is not grounded, be sure to follow the grounding class
D procedure. When you contact it with this product, connect 0V (black) and the grounding point of the power supply and signal cable to being common. But when 0V and the grounding point are not connected to be common, do not connect 0V line to the grounding point. And when you use an optional AC adapter, this product does not need to be properly grounded.
Air Piping:
・ Use clean dry compressed air to deliver the ionized air.
・ Attach an air tube (with an outside diameter of Φ6 mm) to the air inlet of the Ionizer.
・ Connect the air tube via the regulator to the air supply (Air compressor).
・ Supply cleaned air (not containing water or oil) to the Ionizer.
6. Operation:
Caution
・ Always use air when supplying power to the ionizer. Otherwise, the ozone concentrations inside the Ionizer will increase due to electric discharge, which may cause detrimental effect on the main body and its surroundings.
1. Install the equipment at a designated place, and perform power supply wiring, grounding wiring, and air piping.
2. Supply DC24V through the power source connector of the equipment. The power source of high voltage starts and corona discharge is generated at the discharge electrode, producing air ions. When the power source is activated, the green LED (in the normal condition) is on.
3. Open the main valve of the air equipment (installed by your company), and supply air to the nozzle with designated pressure after adjusting the Air pressure. Ionized air is blown out from the nozzle and static electricity of the charged objects placed in the air-flow is neutralized and removed. Pay attention to excessive air pressure, which will lower the effect of removing electricity. (See the table under "Air Pressure
Working Range" under "4. Specifications" for the working range of air pressure.
4. When you attach the tube to the nozzle, move the tip of the tube closer to the charged object and blow ion air.

8. Maintenance:
Warning
・ Before care and maintenance of the product, be sure to turn OFF the power and air. Otherwise damage or operating problems may occur.
・ The tip of the discharge needle is sharp; be careful not to touch the discharge needle.
Caution
・ Clean the discharge needle periodically even if the Cleaning Check signal is not displayed.
(Recommended once every 2 weeks)
・ The electrodes gradually become deteriorated with exposure to alternating high-voltage electric fields. They must be replaced periodically. The expected life span is thought to be 20,000 hours even if sufficient maintenance is conducted, and replacement is recommended after 20,000 hours. If regular maintenance is not performed, the life span of the 966-II will decrease. The maintenance is very important. Position the unit at a place where it is free from water and oil, etc, It gets wet, dry it with a clean cloth.
・ Attachment of contamination to the tip of the discharge needle will deteriorate the static and elimination effect. If deterioration of the static elimination effect is observed, clean the needle and its surrounding area using a nylon
・ brush etc. (Never use a wire brush for cleaning the needle.)
The discharge needle must be replaced periodically.
Replacing the discharge needle unit:
1. Use a screwdriver to rotate the knob at the rear of the discharge needle unit in a FREE (counterclockwise) direction.
2. Pull down the discharge needle unit to the rear.
3. After cleaning the discharge needle, and installing the discharge needle to the main unit, rotate the locked knob of the discharge needle unit in the LOCK direction (clockwise) until the locked knob is securely locked with the main unit. Tightening torque is 8 to 10N ・ cm.
