Working Principle
The 9907-573 continuously samples turbine operating parameters and compares them to programmed setpoints. Through advanced control algorithms, it calculates the necessary corrective actions and outputs signals to valve actuators. Simultaneously, it monitors all safety parameters and initiates protective shutdowns when limits are exceeded.
