4. How Does the BARBER-COLMAN DYN1 10694 Speed Controller Work?
The DYN1 10694 operates by comparing the engine speed signal from a magnetic pickup sensor (MPU) to a setpoint defined by the user or control system. If the actual speed deviates from the setpoint, the controller adjusts the fuel actuator accordingly.
Operational Steps:
- Speed Feedback: MPU provides a real-time pulse signal proportional to engine RPM.
- Error Calculation: Controller compares actual speed vs. desired speed.
- PID Adjustment: The built-in control loop calculates the required correction.
- Signal Output: Controller sends pulse-width-modulated (PWM) signal to actuator.
- Engine Adjusts: Actuator moves to increase or decrease fuel delivery.
This process happens in milliseconds, ensuring real-time speed stabilization.
