The Accurion Halcyonics Vario Basic series is an active vibration isolation system designed to protect sensitive measurement equipment from building vibrations and other disturbing influences. This document provides operating instructions, technical specifications, and maintenance guidelines for the system.
Function Description
The Halcyonics Vario Basic system utilizes active vibration isolation technology based on piezoelectric acceleration pickups, fast signal processing, and electro-dynamic force transducers. It provides active compensation in all six degrees of freedom, effectively isolating equipment from vibrations. The system is designed to automatically switch off during overmodulation (excessive vibration amplitudes) and re-initialize to resume active isolation once the interference subsides, requiring no user intervention.
Important Technical Specifications
The Vario Basic series is available in several standard versions, including 40-100, 60-100, 90-100, 40-300, 60-300, 90-300, 40-600, 60-600, and 90-600. The "-600" versions consist of four isolation elements and a 4-port control unit, while others typically use two isolation elements and a 2-port control unit.

Usage Features
Setting Up the Equipment:
- The system should be placed on a stable, rigid, and flat surface with a planarity of 0.5 mm for optimal performance.
- If placed on a table or bench frame, ensure it is distortion-free and stiff to minimize amplification of structure and airborne noise.
- Select a location with minimal vibration, not exceeding velocities of 500 µm/s.
- Allow 2-3 hours for the system to acclimatize if moved from a cold to a warmer environment before plugging it in and switching on.
Start-up Procedure:
- Set up isolation elements on a flat, stable surface.
- Connect isolation elements to the control unit using D-Sub cables.
- Connect the control unit to AC power.
- Ensure isolation elements are mechanically linked (e.g., by an optical breadboard).
- Center the application on the top plate.
- Perform manual static load adjustment.
- Turn on the power switch on the control unit's front panel.
- Set the active isolation switch to "on" (blue LED indicates status).
Static Load Adjustment and Transportation Lock:
- The top parts of the isolation elements are supported by four steel springs, which must be prestressed according to the static load.
- A peg in a hole at the front of each isolation element indicates the load adjustment status:
- Bottom position: Spring prestressing is too high; reduce prestress by turning the lever from front to side while pushing.
- Top position: Spring prestressing is insufficient; increase prestress by turning the lever from side to front while pushing.
- Middle position: Correct adjustment.
- The lever for adjustment is located on the side of the element and must be moved outside through a hole in the side panel.
- It is crucial to lock the system before transport or movement by adjusting the static load.
Vario Basic Control Unit:
- The control unit features a main power switch and an on/off switch for active isolation mode.
- LEDs on the front panel display sensor signals (yellow) and actuator outputs (red), indicating extreme vibrations or direct table top excitation.
- The blue LED indicates the isolation mode: blinking for initialization/stand-by, solid for active isolation.
- Sensor-actuator units are integrated into the isolation elements, with pictograms on the front panel showing the direction of actuator force (vertical or horizontal).
Overmodulation:
- The system can compensate for vibration amplitudes up to 500 µm/s (for 300/600 kg versions) or 550 µm/s (for 100 kg version).
- If vibrations exceed this level, the system enters stand-by mode (flashing blue LED).
- Active isolation automatically resumes after the overload excitation stops, typically within a few seconds, but up to 30 seconds after a severe overload.
Maintenance Features
Care and Maintenance Recommendations:
- Storage: Store in a dry place, away from rain, liquids, or dampness to prevent short-circuits or corrosion. Avoid dirty or dusty environments.
- Temperature: Do not store in hot environments, as this can compromise performance and reduce lifetime. Avoid cold environments; if moved from cold to warm, allow 2-3 hours for acclimatization before powering on to prevent moisture condensation and circuit failure.
- Handling: Avoid dropping, shaking, or exposing the system to impact or blows, as this can damage integrated electronics and mechanical components.
- Cleaning: Wipe dust from exterior surfaces with a lint-free cloth. Do not use aggressive cleaning agents.
