DESCRIPTION
F9-1-657
The changing of the traction motor electrical connections or transition
is completely automatic during locomotive acceleration or deceleration. There
is no provision for effecting manual transition or for forestalling the automatic
transition.
AUXILIARY EQUIPMENT
104
Storage Battery
Power from a 32 cell, 64-volt, storage battery
is used to start the Diesel engine. The storage battery boxes are located
adjacent to the front end of the fuel tank on each side of the locomotive.
With
the Diesel engine running, the auxiliary generator charges the storage battery.
105
Auxiliary Generator
A 10 KW auxiliary generator, Fig. 1-6, is
driven directly from the rear gear train of the engine through flexible
couplings.
If
the
locomotive
is
equipped with a steam generator, an 18
KW auxiliary generator is used. The
auxiliary
generator
produces
direct
current at 74 volts to charge the battery
and supply the low voltage circuits for
lighting, main generator battery field
excitation and fuel pump operation.
106
Traction
Motor
Blowers
Each unit is equipped with four
alternating
current
driven
traction
motor blower motors, Fig. 1-7. Each
motor has a fan, or blower wheel,
mounted on its rotor shaft and supplies

cooling air to one traction motor. The speed of the blower motor varies in
proportion to the speed of the Diesel engine.
107 Radiator Cooling Fans
Four alternating current driven cooling fan
motors, Fig. 1-8, are mounted in
the roof of the locomotive above
the cooling water radiator sections.
A fan mounted on each rotor shaft
draws air through the radiator,
removing heat from the engine
cooling water. The speed of the
cooling fan motor varies in pro-
portion to the speed of the Diesel
engine.

Air

A
3-
cylinder, two stage water cooled
air compressor, Fig. 1-9, is driven
through aflexible couplingfromthe

F9-1-657
locomotive is equipped with a Model WBO air compressor which has a rating
of 234 CFM displacement at 835 RPM.
109 Fuel Pump
The fuel pump is driven by a separate direct current electric
motor through a flexible coupling. The pump assembly is mounted on the
equipment rack which supports the engine cooling water tank. To operate the
fuel pump, the "Fuel Pump" switch on the engine control panel and the
"Control" switch on the engineman's control panel must be ON.
OPERATING CONTROLS
Three levers and two brake valve handles control the entire operation
of the locomotive. These are the throttle, reverse and selector levers, mounted
in the controller, Fig. 1-10, and the independent and automatic brake valve
handles.
110 Throttle Lever
This lever, Fig.
1-11, controls the speed of the
engines and the train speed in
normal operation. The position of
the throttle is indicated bythe upper
band of the illuminated indicator
located in the upper left hand corner
of the controller. The throttle has
ten positions, Stop, Idle and running
speeds 1 to 8. Stop can be obtained
by pulling the throttle lever out
away
from
the
controller
and
pushing it one step beyond the idle
position; this stops all engines. Idle
position is as far forward as the
-105 –

DESCRIPTION
throttle lever can be moved without pulling it
out away from the controller. Each running
notch on the throttle increases the engine
speed 80 RPM from 275 RPM at idle to 835
RPM at full throttle. The throttle may be
openedas rapidlyas desired PROVIDING
OPERATING CONDITIONS AND TRAIN
CONSIST PERMITS. Normally, the throttle
should be opened one notch at a time. The
throttle may be closed completely with one
motion in an emergency, but should be
closed only one notch at a time in normal
operation.
111
Reverse Lever
The reverse
lever, Fig. 1-12, has three positions:
FORWARD,
NEUTRAL
AND
REVERSE.
Direction in which
the locomotive moves is controlled
by movement of this lever to the
forward or reverse position. With the
reverse lever in neutral, no power
will be developed if the throttle is
opened, even t h o u g h the engine
speed will increase. The reverse
lever should be moved ONLY when
the locomotive is standing still.
The reverse lever can be
removed from the control stand only
when the lever is in the "Neutral"
position, the throttle is in

F9-1-657
"Idle" and the selector lever is in "Off." Removal of the reverse lever
locks the operating controls in the controller. Remove the reverse lever
from all nonoperating control stands.
112
Selector Lever
F9,
FP9
and
FL9
locomotives
are
basically equipped with automatic transition. On such locomotives
transition is FULLY AUTOMATIC, both forward and backward, and
no provision is made basically for making transition manually on such
units. However, a selector lever is supplied with "A" units solely for the
purpose of controlling dynamic braking and/or effecting manual
transition on units not equipped with automatic transition coupled to F9
type locomotives.
The position of the lever is indicated by the lower indicating
band illuminated through the opening at the upper left corner of the
controller front panel. Movement of this lever all the way in one
direction will index the selector cam one notch in that direction. The
lever is spring loaded and must be allowed to return to center position
before indexing again in either direction.
When the selector is put in the braking "B" position, a
mechanical arrangement lifts the throttle cam drum vertically to
disengage the power switches and engage the braking switches. In this
position the throttle handle moves freely (without notching) to control a
500 ohm braking rheostat. (See Art. 229 for dynamic brake operation.)
113 Mechanical Interlocks On The Controller
The levers on the
control stand are interlocked so that:
1. Reverse lever in NEUTRAL.
a.
Throttle may be moved to any position.
b.
Selector may be moved between OFF and 1 (or the 1-4 range
if used).

Throttle may be moved to any position.
b.
Selector may be moved to any position.
3.

a. Reverse lever may be moved to any position.
b. Selector may be moved to any position.
4.
Throttle above IDLE.
a.
Reverse lever position cannot be changed.
b.
Selector is locked in either B or 1 (or the 1-4 range if used).
5.
Selector in OFF.
a.
Reverse lever may be moved to any position.
b.
Throttle may be moved to IDLE and STOP.
6. Selector in 1 (also 2, 3 and 4 when used).

Reverse lever may be moved to any position.
b.
Throttle may be moved to any position.
7.
Selector in "B."
a.
Reverse lever cannot be moved.
b.
Throttle may be moved to any position.
Where positions 2, 3 and 4 for manual transition are
incorporated in the selector, this lever may be moved from 1 to these
positions if the reverse lever is in FORWARD or REVERSE, and with
the throttle in any position. Permissible movement of the throttle and
reverse levers with the selector in 2, 3, or 4 is the same as with the
selector in 1.
