Figure 1-1 - Remote Set Regulator

The CPU, clock and reset circuitry performs the timing, measurement and decision making functions of the Remote Set Regulator. This circuit analyzes the comparator outputs and sends data to the stepper driver which, in turn, pulses the stepper motor in either direction. Since the driveshaft of the stepper motor is mechanically coupled to the feedback pot and a pressure regulator valve, both will be set in accordance with data received from the CPU.
