A system for controlling the hydraulically actuated components, including
snow-ice control components carried by a truck. The system employs a
hermetically secure composite housing mounted externally of the truck cab
on the truck frame which retains a unique hydraulic reservoir in
combination with a manifold supporting a plurality of solenoid actuated
hydraulic valves and an associated electronic drive circuitry including a
slave controller having a bidirectional data transmission port. That port
communicates through a single bidirectional transmission bus with a
master controller retained within an operator interface control console
mounted in the truck cab. That control console also will contain a slave
interface controller, as well as a slave datalog and communications
controller.
