TEC
The Greensmaster machine use a Toro Electronic Controller (TEC) to manage
the machine electrical functions. The controller is a microprocessor controlled
device that senses the condition of various switches (inputs) and directs electrical
power to control the appropriate 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 InfoCenter display on the console. If a problem exists that
could prevent normal operation, the InfoCenter display will display an operator
advisory or fault code to assist in identifying the problem.
The TEC is attached to the battery mount inside the battery cover; refer to
Figure
51.
Before performing any welding on the machine, do the following to
prevent damaging the electrical system of the machine:
- Disconnect the machine connector from the lithium battery pack.
- Disconnect the wire harness connectors from the Toro Electronic
Controller.
Note: If the TEC is replaced for any reason, the machine software must be
updated; contact an Authorized Toro Distributor for assistance.
The inputs from the key switch, traction switch, throttle potentiometer, and clutch
bail potentiometer are all monitored by the TEC.
The TEC current output to the electric motor precharge circuit, main contactor,
12 VDC outputs (InfoCenter display and optional hour meter), and 5 VDC output
(throttle potentiometer and clutch bail potentiometer) are controlled based on
the inputs received by the controller.
