The Control System includes the Driver Box (main controller) and the Dashboard Panel. The Dashboard
Panel communicates with the Driver Box via a CAN Bus. The Driver Box controls the machine electrical
and hydraulic systems by actuating the appropriate pumps and solenoid valves to perform the required
scrubbing, sweeping and drive functions.
The Driver Box communicates with the Engine System controller on the Kubota LPG engine, and
the APECS 3000 Governor on the Kubota diesel to monitor engine parameters. The Driver Box also
communicates with the Relay PCB which provides the engine start and run signals.
