Control Assembly: Description and Operation





Control Panel Head
This component is the actual control unit of the system. All of the system's electronic circuitry is now incorporated in this unit and digital processing logic is used.

The control head receives inputs from the driver and the system's components. It then processes this information and operates the appropriate components. The system's fault memory is also located in this unit.
