General Information

Operator's Manual

The Operator's Manual provides information regarding
the operation, general maintenance and maintenance
intervals for your Greensmaster machine. Refer to that
publication for additional information when servicing the
machine.

Electrical Drawings

The electrical schematic and wire harness drawings for
Greensmaster TriFlex 3300 and 3400 machines are lo-
cated in Chapter 10 -- Foldout Drawings.

Toro Electronic Controller (TEC)

Greensmaster TriFlex 3300 and 3400 machines use a
Toro Electronic Controller (TEC) to manage machine
electrical functions. The controller is microprocessor
controlled that senses the condition of various switches
(inputs) and directs electrical power to control appropri-
ate machine functions (outputs) based on the inputs.
The status of inputs to the controller as well as outputs
from the controller can be monitored with the Diagnostic
Display (see Special Tools in this chapter).
IMPORTANT: Before performing any welding on the
machine, disconnect the battery cables from the
battery, disconnect the wire harness connector
from the Toro Electronic Controller(s) and discon-
nect the terminal connector from the alternator.
These steps will prevent damage to the machine
electrical system.
CAN- -bus Communications
The TEC controller communicates with other electrical
components on a CAN--bus communication system.
The CAN--bus system reduces the number of electrical
components and connections used on the machine and
allows the number of wires in the wire harness to be re-
duced.
CAN identifies the Controller Area Network that is used
on the Greensmaster. Two (2) twisted wires form the
bus. These wires provide the data pathways between
machine components. The engineering term for these
two (2) wires are CAN--high and CAN--low. At the ends
of the twisted pair of bus wires are 120 ohm termination
resistors.
Greensmaster 3300/3400
1. TEC controller
Each of the components that is controlled by the CAN--
bus link only needs four (4) wires to operate and commu-
nicate to the system: CAN--high, CAN--low, B+ (power)
and ground.
IMPORTANT: The termination resistors at the ends
of the bus wires are required for proper electrical

system operation.
