Truck Control Interface Panel (Tci) - Komatsu 930E-2 Shop Manual

TRUCK CONTROL INTERFACE PANEL (TCI)

The Truck Control Interface Panel (TCI) (17FL349 or
17FL373) is the main interface between truck systems
and devices and service personnel. This panel is used
in conjunction with the Diagnostic Information Display
(DID) described later.
The TCI panel provides the following functions:
• Communicates with the Propulsion System
Controller (PSC) to exchange propulsion con-
trol system status and control data and to pro-
vide the PSC with truck systems status data.
• Communicates with the Diagnostic Informa-
tion Display (DID) to exchange PSC and/or
TCI diagnostic and parameter data.
• Communicates with the Auxiliary Blower Sys-
tem to exchange diagnostic data.
• Communicates with a Portable Test Unit
(PTU) to exchange TCI data.
• Communicates with a Modular Mining Dis-
patch System to exchange truck status data.
• Monitors engine control system, payload infor-
mation, ambient and propulsion system tem-
perature, operator control inputs etc.
• Controls the engine start sequence.
• Provides signals to activate many of the cab
mounted warning lamps and gauges. Con-
trols the park brake solenoid.
• Processes front wheel speed signals for the
PSC and speedometer.

Electrical Propulsion System Components
» *17FB127 Power Supply: Supplies regulated
+15VDC, -15VDC, and +5VDC from the filtered
battery supply (B+) input.
» 17FB144 CPU Card: Provides high speed
RS422 serial communications to PSC and
RS232 serial communication with the PTU.
» 17FB160 Analog I/O Card: Provides RS232
serial communications with Diagnostic Informa-
tion Display and an optional Modular Mining
Dispatch System. Provides RS422 serial com-
munication with the Auxiliary Blower System.
Receives signals for front wheel speed, motor
cooling and barometric air pressures, accelera-
tor, retard speed setting, payload, ambient and
hydraulic oil temperature, and engine cranking
voltage. Outputs drive cab mounted tempera-
ture gauges etc.
» 17FB104 Digital I/O Card: Receives operator
control, engine and body-up signals. Provides
engine start controls, drives cab mounted indi-
cator/warning lamps, etc.
