The Groundsmaster 4500-D machines use a single Toro Electronic Controller
(TEC-5004) to manage machine electrical functions. Groundsmaster 4700-D
machines uses two (2) TEC controllers (TEC-5004) for machine operations. The
TEC controllers are microprocessor controlled that sense the condition of various
switches and sensors (inputs). The controllers then direct electrical power
to control appropriate machine functions (outputs) based on the input state.
The communication between the two (2) TEC controllers, the Yanmar engine
electronic control unit (ECU) and the machine InfoCenter display is provided with
a CAN-bus system. The status of inputs to the controllers as well as outputs from
the controllers can be monitored with the InfoCenter display.
