The Accurion halcyonics_i4 series is a line of active vibration isolation desktop units designed to protect sensitive measurement equipment from building vibrations and other disturbing influences. These systems utilize Accurion's advanced control technology, based on piezoelectric acceleration pickups, fast signal processing, and electro-dynamic force transducers, to provide active compensation in all six degrees of freedom. This ensures optimal performance for a wide range of scientific and industrial applications.

Function Description:

The primary function of the halcyonics_i4 system is to actively isolate equipment from environmental vibrations. It achieves this by sensing incoming vibrations and generating counter-forces to cancel them out. The system is designed to compensate for vibration amplitudes up to 500 µm/s. If vibrations exceed this level, the system temporarily enters a stand-by mode, indicated by a flashing blue "Isolation" LED, and automatically re-initializes once the overload subsides. This active isolation capability is crucial for applications requiring high precision and stability, such as microscopy, metrology, and semiconductor manufacturing.

The system features an "Automatic Load Adjustment and Transport Locking Mode." The top plate is supported by four steel springs, which are pre-stressed by electric motors to elastically support the payload. This "load adjustment" mode (indicated by a green LED) automatically positions the top plate optimally based on the load. For initial setup or after load changes, this mode should be activated. A "neutral" mode (LED off) deactivates automatic load adjustment, preventing unwanted motor activation. Crucially, for transportation, a "transport locking mode" (red LED) must be activated. In this mode, the steel springs are pre-stressed to their maximum, creating a rigid mechanical contact between the top and bottom of the system, thereby protecting sensitive components from damage during movement. It is imperative that no load is placed on the isolation system during transport.

- i4medium + i4 large: 0 - 105 kg (231 lbs) or 40 - 150 kg (88 - 330 lbs).
*Floating table top is supported by steel springs; low-pass characteristics of spring-mass combination dominates the dynamic behaviour above 200 Hz.
**The settling time and maximum compensation level depend on several conditions, such as payload, frequency, load distribution and height of the payload. For that reason this value should be considered as an estimation.
***The response time determines when the system starts to actively isolate an incoming vibration after detection by the sensors.
