Groundsmaster 5900 and 5910 machines use two (2) Toro Electronic Controllers
(TEC) to manage machine electrical functions. The TEC is a microcontroller that
monitors the condition of various machine switches and sensors (inputs) and
directs electrical power to control appropriate machine functions (outputs) based
on the state of the inputs. Communication between the two Toro controllers,
the Yanmar engine controller and the InfoCenter Display is provided by a CAN
bus network. The status of inputs to the controllers as well as outputs from the
controllers can be monitored with the InfoCenter Display (see
SCREENS (page 6–22)).
The TEC controllers are attached to the machine under the front power center
cover behind the operator seat
they are programed in a "master/slave" configuration and therefore cannot be
interchanged. The master controller is primarily responsible for managing the
engine start signal and interlocks. The slave controller is primarily responsible
for managing cutting unit operation.
