Installation Guide
- Mount the bar at 50 to 2000 mm from the target.
- Keep the effective length aligned with the static area.
- Use Rc 1/8 air connection for clean dry air.
- Set air pressure between 0.1 and 0.5 MPa.
- Recommended pressure is 0.2 MPa for best balance.
- Connect 24 to 36 VDC power with correct polarity.
- Use NPN open collector signals for control and alarm.
- Do not exceed 100 mA on control output.
Setup and Maintenance Convenience
The Hi-Power I.C.C. method simplifies ion balance control. Remote control communication allows system-level monitoring. The shockless resistive coupling design improves operator safety. Tungsten electrodes resist wear in long-duty cycles. Regular cleaning of electrodes helps maintain stable ion output. No built-in ports reduce wiring complexity. The 3.00 kg body supports stable mounting on production lines.
