COMPONENT FUNCTION
AFSE 36
Alternator Field Static Exciter
Panel (17FM466)
Regulates current in the alternator field based on firing
pulses from the PSC.
AFVLT 21
Alternator Field Voltage Divider
Panel (17FM363)
Attenuates high voltage output from the AFSE to an
acceptable level for use by the Analog I/O card in the
PSC.
ALT Alternator (5GTA34)
Main alternator, propulsion and control system.
ANALOG
I/O CARD
System analog input/output card
(17FB143)
Provides signal conditioning for analog signals to and
from the TCI and PSC.
AUX BLOWER
MOTOR
Auxiliary Blower Motor (5GDY84)
A 3-phase, AC induction motor mounted in the blower
assembly behind the electrical cabinet. Used to drive two
blowers for cooling the traction motors and control
cabinet components.
AXCAP 11
Auxiliary Power Filter Capacitor
Bank
Used with the AXIND to filter the regulated DC voltage
from the Auxiliary Phase Control Rectifier into a smooth
DC supply suitable for use by the Auxiliary Power Inverter.
AXFU1, 2 33
Auxiliary Power Rectifier Input
Fuses 1 and 2
Provide overload protection for the Auxiliary Power
Inverter/Phase Control Rectifier.
AXIND 30 Auxiliary Power Filter Inductor
Used with the AXCAP to filter the regulated DC voltage
from the Auxiliary Phase Control Rectifier into a smooth
DC supply suitable for use by the Auxiliary Power Inverter
AXINV 29
Auxiliary Phase Control Rectifier
and Power Inverter Module
The Auxiliary Phase Control Rectifier converts the
3-phase, AC input voltage from the Alternator to
regulated DC voltage and supplies the regulated voltage
through a filter to the Auxiliary Power Inverter. The
Auxiliary Power Inverter inverts the regulated, filtered, DC
voltage into a variable voltage, variable frequency,
3-phase output to power the Auxiliary Blower Motor.
ASYN 35
Alternator Synchronization
Transformer
Monitors frequency of the tertiary winding and provides a
sample of the frequency to the PSC, which uses the input
to synchronize the firing pulses sent to the Alternator
Field Static Exciter Panel (AFSE).
A3PV 4
Alternator 3-phase Voltage
Measuring Module (17FM458)
Attenuates high voltage from two phases of the Alternator
to a level acceptable to the Analog I/O card in the PSC.
