16Service Manual – SC6000
04 - Control System
Functional Description
Within the SC6000 system there are three primary controllers: the Main Machine Controller (E2), the
Power Module (E3), and the Wheel Drive controller (E4). The three modules communicate with one another
via a CAN Bus (Controller Area Network).This permits each of the modules to perform their separate
functions, while still functioning as a complete system. (There is also a second, separate CAN Bus between
the Main Machine Controller and the optional TrackClean Module.)
