1000middotHP DIESELELECTRIC LOCOMOTIVE

b When wheel slipping occurs on locomotives without power-removal feature the throttle should be partially closed until the buzzer stops indicating that the wheel slipping is over When wheel-slip buzzer operates on locomotives with power-removal feature partially close the throttle only if there is a chance of the wheels slipping again Advance throttle slowly when the possibility of the wheels slipping is past

4 Ground Relay

a Automatic indication of a ground in the electric appara tus is provided by means of a ground relay GR in the generator circuit

b When the ground relay pulls in 1 fdE con tactor opens

a Exciter field is disconnected from battery to greatly decreased main-generator voltage

2 GF contactor opens

a Main-generator field is weakened by fiEE resistor This decreases the generator voltage

c Reset Ground Relay

1 Close throttle to Idle position 2 Reset relay by raising the holding latch 3 If a ground persists open switch 108 The locomotive

should not be moved any farther in this condition than is necessary to get it in the clear

5 Diesel-engine Overspeed Trip

Diesel engine overspeed will automatically operate the overspeed trip

a Cutout shaft pulls the trip pins on the cutout plungers b High-pressure fuel-injection pumps stop c Diesel engine stops d Reset the overspeed trip lever Follow instructions given

Section I

Schematic Connection Diagram The diagrams and photographs in this section will help operashy

tors understand the apparatus and circuits involved in the operation of the Alco-G-E l000-hp diesel-electric locomotive

Symbols denoting control devices with current-carrying conshytacts are underlined For example the auxiliary-generator contactot AI is underlined but the same symbol AI referring to the auxiliary generator is not underlined Fig 4 Master schematic connection diagram page 21

This diagram locates the individual circuits and is used as a reference to the various detailed schematic diagrams Fig 5 Main power circuit with transition relay wheel-slip relay and ground relay page 22

This circuit includes the main-generator armature and comshymutating field the differential field of the exciter and the four traction motors The transition relay together with the wheelshyslip and ground relays are a part of this circuit Fig 6 Generator excitation circuit page 23

The main-generator shunt field is excited by the exciter armashyture The exciter shunt field has a component of self-excitation from its own armature and another component of separate excitation from either the battery or the auxiliary generator

This circuit also includes the excitation resistors and the throtshytle soft-starling switch Fig 7 Power and cranking circuits page 24

The diesel engine is cranked by power supplied to the mainshygenerator armature commutating field and starting field from the battery which operate the generator as a motor to turn over the engine The starting field is automatically cut out of the cirshycuit as soon as the engine-starting button is released Fig 8 Auxiliary-generator Voltage-regulating-relay and batteryshychargJng circuits page 25

The auxiliary generator furnishes power for operating the conshytrol apparatus and while the engine is running supplies separate excitation to the exciter field

The battery is charged from the auxiliary generator as soon as its voltage is high enoughto operate the shunt coil of the reverseshy

current relay which closes the battery contactor If the auxiliaryshygenerator voltage drops below the battery voltage the relay opens the battery contactor to prevent reverse current flowing from the battery to the auxiliary generator Fig 9 Engine-starting c01trol and alarm circuits page 26

The governor solenoid and pressure switch together with their interlocks and resistors and the auxiliary-generator field with its regulating-relay contacts and resistors are on the same control switch as the fuel-pump motor They are connected in this way so that the fuel pump will operate and fuel be available before starting the engine

The fuel-pump circuit also takes the inductive kick of the auxiliary-generator field when the control switch is opened This is part of the engine-starting circuit and it must function propshyerly before the diesel engine will start The operating coils of the starting contactors GSI and GSZ should be energized only while starting the diesel engine This condition is obtained by intershylocking the coil circuits of the starting contactors to the ll and JE contactors and two fingers and cams of the controller The wheel-slip buzzer and the overload indicating lamp together with their operating-relay contacts are also included on the diagram Fig 10 Traction control circuits page 27

This diagram is used to show the electric connections which give the correct operation of the traction-motor control devices Figs 11 and 13 Coil and contact positions on relays and conshytactors pages 28 and 30

These diagrams locate the individual control devices and are used as a reference to the various detailed schematic diagrams The circuit of the device as a part is indicated by a reference to the right of the diagram Frequently the separate parts of the respective devices will be found on different diagrams Fig 12 _ I nterior of control-apparatus compartment oblique rightshyside view page 29

The photograph of the right side of the contactor compartshyment shows the control equipment as it actually is mounted on the locomotive Fig 14 Interior of control-apparatus compartment oblique leftshyside view page 31

This photograph shows the control equipment arrangement on the left side of the contactor compartment Fig 15 Resistors in control-apparatus compartment page 32

Operating Tem on Control Rela anel Other Device

Correct operation of the various control devices can be checked by means of the tests listed below

These tests should also be used if it is ever necessary to locate a source of trouble

Instructions must be carefully followed to avoid danger to oneself and damage to the equipment

Make all tests with diesel engine shut down and with main battery switch No 100 closed
