The manual emphasizes that the 3501 is a passive device. It does not generate its own voltage; rather, it creates a voltage divider circuit. The motor controller supplies a reference voltage (usually 5V or 10V) to one terminal, a ground to another, and the wiper terminal outputs a varying voltage proportional to pedal position. The manual emphasizes that the 3501 is a passive device
