- Environmental Conditions: Verify the operating temperature (0°C to 40°C) and humidity levels match your application’s environment.
- Software Integration: Confirm compatibility with your control system’s software (e.g., LabVIEW, MATLAB) using the provided drivers.
Precautions
- Installation:
- Mount the controller in a well-ventilated area to prevent overheating; avoid direct exposure to moisture or dust.
- Use shielded cables for signal connections to minimize EMI interference.
- Operation:
- Do not exceed the rated output voltage or current to prevent actuator damage.
- Calibrate the system using the ZYGO Alignment Tool before initial use to ensure optimal performance.
- Maintenance:
- Regularly update firmware via the ZYGO Control Suite to access the latest features and bug fixes.
- Inspect cooling vents quarterly and clean with compressed air to maintain thermal efficiency.
