1. TDM display/controller
2. LED fault active indicator
The TDM display/controller is an LCD device located on the operator's console
that presents operating hours, engine coolant temperature, electrical system
voltage, engine RPM, and active faults. The display screen button located
next to the TDM is used to select the various display screens. A red LED
active fault indicator is also part of the TDM display/controller. Refer to
Display/Controller (page 6–3)
Power for the TDM is available when the main power relay is energized (key
switch is in the ON or START position). A 15 Amp fuse (FB1–F4) protects the
TDM power circuit.
The TDM display/controller is also a 2001 series 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. The status of inputs to the controller can be monitored with
the TDM display/controller screens; refer to
Screens for Troubleshooting (page
The TDM display/controller, the Yanmar Engine Control Unit (ECU) (models
31902 and 31903), and the optional controllers (future attachments) used on the
Greensmaster 3200/3300/3310 machines communicate with each other on a
Controller Area Network (CAN) bus system.
