Truck Control Interface (TCI)
The TCI is the main interface between the truck
systems/devices and service personnel. This panel is
used in conjunction with the DID panel.
The TCI panel provides the following functions:
• Communicates with the PSC to exchange
propulsion control system status and control data
and to provide the PSC with truck systems status
data.
• Communicates with the DID panel to exchange
PSC and/or TCI diagnostic and parameter data.
• Communicates with a PTU to exchange TCI data.
• Communicates with a Modular Mining Dispatch
System to exchange truck status data.
• Monitors engine control
information, ambient and propulsion system
temperature, operator control inputs, etc.
• Controls the engine start sequence.
• Provides signals to activate many of the cab
mounted warning lamps and gauges. Controls
the parking brake solenoid.
• Processes the front wheel speed signals for the
PSC and speedometer.

Electrical Propulsion System Components
The TCI contains the following internal, removable
printed circuit boards:
CPU Card: Provides high speed communications
to PSC and RS232 serial communication with the
PTU.
Analog I/O Card: Provides RS232 serial
communications with the DID and an optional
Modular Mining Dispatch System. Receives
signals for front wheel speed, motor cooling and
barometric air pressures, accelerator, retard
speed setting, payload, ambient and hydraulic oil
temperature, and engine cranking voltage.
Outputs drive the cab mounted temperature
gauges.
Digital I/O Card: Receives operator control,
engine and body-up signals. Provides engine
start controls and drives the cab mounted
indicator/warning lamps.
