Working Principle
The controller continuously monitors all turbine parameters through its I/O system. It executes complex control algorithms to maintain operating setpoints while simultaneously checking all safety limits. If a parameter exceeds a safe threshold, the controller initiates the appropriate corrective action or protective trip, ensuring equipment and personnel safety.
Installation Requirements
- Follow all grounding and shielding guidelines to ensure EMI immunity.
- Provide adequate clearance around the controller for ventilation and maintenance access.
- Connect all safety circuits according to applicable safety standards.
Usage Precautions
- Always verify protection setpoints and trip logic before initial start-up.
- Perform regular functional testing of all safety circuits and protection relays.
- Keep firmware and configuration backups current and stored securely.
