TECHNICAL BULLETIN TB-6590 Mini Zero Volt Ionizer 2 Made in the Installation, Operation and Maintenance United States of America The primary method of static charge control is direct connection to ground for conductors, static dissipative materials, and personnel. A complete static control program must also deal with isolated conductors that cannot be grounded, insulating materials (e.g., most common plastics), and moving personnel who cannot use wrist or heel straps or ESD control flooring and footwear. Air ionization is not a replacement for grounding methods. It is one component of a complete static control program. Ionizers are used when it is not possible to properly ground everything and as backup to other static control methods. In clean rooms, air ionization may be one of the few methods of static control available. (ESD Handbook ESD TR20.20 Ionization, section 5.3.6.1 Introduction and Purpose / General Information) The EMIT Mini Zero Volt Ionizer 2 operates on Steady-State Figure 1. EMIT 50642 Mini Zero Volt Ionizer 2 DC. Steady-State DC systems consist of separate negative and positive ion emitters connected by a pair of high-voltage Description cables to their respective high-voltage power supplies. DC power is constantly applied to the emitter points. The ionizer The EMIT 50642 Mini Zero Volt Ionizer (ZVI) 2 is a compact utilizes feedback from the internal sensor grill to continuously bench top ionizer used for neutralizing electrostatic charges adjust the output to maintain balance. on insulators and ungrounded conductors in a 6 x 24 coverage area. Its compact size (5.3 high x 3.5 wide x EMIT offers the following accessories for the Mini Zero Volt 1.7 deep with stand) allows it to be used in confined spaces Ionizer 2: such as environmental chambers and automated equipment.

Per ANSI/ESD 1 Certificate of Calibration S20.20 section 6.2.3.1. Protected Areas Requirement states: Ionization or other charge mitigating techniques shall be used at the workstation to neutralize electrostatic fields on all process essential insulators if the electrostatic field is considered a threat. Air ionization can neutralize the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When an electrostatic charge is present on objects in the work environment, it will be neutralized by attracting opposite polarity charges from the ionized air. Note that ionization systems should not be used as a primary means of charge control on conductors or people. Figure 2.

It will illuminate orange and sound the buzzer should the ionizer experience circuit failure or its emitter pins become too dirty to operate effectively. Installation Place the unit at a desired location where that the airflow will not be restricted. The Mini ZVI 2s compact size and mountable stand allow it to be installed in confined spaces such as enviornment chambers and automated machinery. Connect the ground cord to the ionizers ground jack. Attach the ring terminal end of the ground cord to a ground point. The face plate screw of a grounded AC wall outlet may provide a convenient connection point. Operation 1. Set the fan speed switch to the LOW or HIGH position. Higher airflow will result in faster neutralization rates. Figure 5. Using the Mini Zero Volt Ionizer 2 inside 2.
