SYSTEM COMPONENTS
AUXILIARY BLOWER SYSTEM
The Auxiliary Blower System, mounted behind the
main electrical cabinet, consists of the blower assem-
bly and control electronics; power inverter/phase con-
trol rectifier, power filter capacitor bank, and power
filter inductor.
The control electronics provide a 3-phase, AC, vari-
able voltage/variable frequency output to the blower
motor. Output frequency (blower motor speed) is con-
trolled by the PSC.
PROPULSION SYSTEM CONTROLLER (PSC)
The PSC (17FL320 Panel) is the main controller for
the AC Drive System. The Panel receives input signals
from speed sensors mounted on the alternator and
traction motors, voltage and current feedback signals
from various control devices, and status/command
inputs from the Truck Control Interface (TCI). Using
these inputs, the PSC controls the two Inverters, re-
tarding circuits, relays, contactors, and other external
devices to provide:
•
Propulsion and wheel slip control
•
Retarding and wheel slide control
•
Engine speed control
•
Auxiliary blower speed control.
•
Event detection
•
Initialization of the necessary operating restric-
tions, including the shut down of the truck if a
serious system fault (event) is detected. If the
fault is not serious, an indicator lamp alerting
the operator to the problem will illuminate. All
event data is recorded for future review by
maintenance personnel.
•
Log event data
•
Store statistical data of the history of various
component and system function operations.
•
Communicate with the TCI to exchange pro-
pulsion system status and control data (event
data, statistical data, etc.) and to receive re-
quired truck systems status data.
•
Communicate with the TCI to exchange pro-
pulsion PTU data (propulsion real time, his-
tory, diagnostic, and parameter data: software
code etc.)
•
Drive the operator cab status and warning
lamps.
The PSC contains the following internal, removable
printed circuit boards and an external fiber optic board.
Brief descriptions of board functions are as follows:
» 17FB127 Power Supply: Supplies regulated
+15VDC, -15VDC, and +5VDC for internal
panel use and
±
15VDC external circuits.
» 17FB147 System CPU Card: Provides serial
communications and control functions;
RS232 communications to PTU.
RS422 high speed communications to TCI.
Microprocessor controls for internal panel cir-
cuits.
» 17FB104 Digital I/O Card: Receives digital in-
puts and feedback information from various pro-
pulsion and control system components.
Digital outputs drive propulsion system contac-
tors, relays and provide equipment enable com-
mands.
» 17FB143 System Analog I/O Card: Receives
engine and auxilary blower speed signals, volt-
age and current signals for main alternator, link
voltage and current, retard pedal input, retard
lever input.
Controls retard effort, engine speed request,
Auxiliary Blower speed, AFSE firing pulses.
» *17FB134 Inverter 1, 2 I/O Cards (2 ea.): Re-
ceives motor speed signals, link voltage, phase
voltages, and phase currents for use by the In-
verter 1 & 2 CPU cards. (See note below.)
» *17FB138 Inverter 1, 2 CPU Cards (2 ea.):
Microprocessor control for inverters 1 & 2. Con-
trols GTO phase modules through the Fiber Op-
tic Assembly. Phase module status is returned
via a separate Fiber Optic Assembly. (See note
below.)
» 17FB172 Inverter 1, 2 CPU and I/O Cards (2
ea.): These cards are used in later production
model trucks equipped with 17FL320E1 PSC
Panel and replace the 17FB134 and 17FB138
cards.
*Note: Early production trucks equipped with
17FL320D1 Panel have 17FB134 and 17FB138 cards
installed instead of 17FB172 cards.
» Fiber Optic Assembly: Provides electrical iso-
lation for control and feedback signals for
Phase Modules and Chopper Modules.
