1. Primary controller T1: TEC
Outcross 9060 machines use a primary controller (T1: TEC) to manage machine
electrical functions. The T1: TEC is a 5004 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 T1: TEC works in conjunction with the T2: TDM to
manage the engine start and run signals, the electric fuel pump, and the various
hydraulic solenoid valves. The status of inputs to the controller as well as outputs
from the controllers can be monitored with the InfoCenter Display; refer to
the InfoCenter Display for Troubleshooting (page
The T1: TEC is attached to the machine under the main instrument panel.
Power for the T1: TEC logic and memory is available at all times (unswitched).
The logic and memory circuit is protected by a 2 Amp fuse (F−B2). Power for
the T1: TEC outputs is available when the main power relay is energized (key
switch is in the ON or START position). A series of four 7.5 Amp fuses (F−A1,
B1, C1, and D1) protect the T1: TEC output circuits.
