PREMIER GP 7/9 DIESEL ENGINE

OPERATING INSTRUCTIONS

Thank you for purchasing the Premier® production of General Motors’ GP

7/9 diesel engine. The engine’s durable ABS body and die-cast trucks are

traditionally sized for operation on most O-31 Gauge track. The engine

should operate for years with most compatible AC transformers (see the

chart on page 31 for a list of compatible transformers) and is completely

compatible with most 3-rail locomotives, rolling stock and accessories.

The locomotive is equipped with Proto sound® Digital Sound and train

control system which contains several deluxe features that are simple and

fun to operate. Each feature is described among the following pages which

should be read before the engine is operated. For those of you who can’t

wait to get started, theQuick Start Basic Operating Instructionsfound on

Pages 3 and 4 should be read so that you understand the basics of the

operating system. Please note that some features are only found in the

Proto sound® models and are marked as such. Features not marked as

Proto sound® features are available in all models.

QUICK START - BASIC OPERATION

The GP 7/9 contains state-of-the art electronics with several built-in

automatic features for incredibly realistic operation. Despite these advanced

features, the GP 7/9 is easy to operate with any compatible standard AC

transformer (see the compatibility chart on page 31).

All models are controlled by a Proto sound® ECRU® electronic reverse

unit. The reverse unit operates in the same manner that all reverse units

function by using forward, neutral and reverse states that are entered each

time the throttle is turned on and off or by using the transformer direction

switch (if so equipped).

The reverse unit is designed to

ignore dirty track, dead spots on

switches or minor short circuits

without disrupting the engine

operation, even at slow, prototypical

speeds. Once the engine is placed

on the track, the throttle on the

transformer can be advanced. You

will see that only the engine’s lights

come on and that only two dings of

the Proto sound® bell occur

followed by the diesel start-up

sounds (on Proto sound® equipped 3-rail models). The engine does not

run. This is known as the RESET

state and is explained in more

detail beginning on Page 4. The

Proto sound® ECRU® will not

power the motors until the throttle

is turned OFF and then ON again.

At this point, the engine will now

function just like any other

electronic or mechanical E-unit. On Proto sound® equipped engines, the

diesel engine sounds will change in volume as the engine begins to move.

The horn can be activated by pressing the whistle button on the transformer

just as any horn would be activated. See the sections later in this guide,

beginning on page 5, for more information on activating the horn and bell

sounds.

Proto sound® DCRU® REVERSE UNIT

As mentioned in the Basic Operating section, the engine is controlled by a

Proto sound® DCRU® reverse unit that contains the standard

forward-neutral-reverse states found on most reverse units. However, as

described earlier, when power is first applied to the track, the reverse unit

begins in RESET or what seems like a neutral state. Power must be

interrupted again to get the locomotive to enter the forward state. It is this

first RESET state that gives ProtoSound® its unique, remote controlled

functions. The system will enter RESET whenever power to the track is off

for three or more seconds. NEUTRAL will be referred to as the state

between Forward and Reverse.

ProtoSounds® is equipped with a microprocessor, that, depending on the

amount of memory it is allotted, allows the user to utilize several remotely

activated functions. In the simplest terms, ProtoSounds® has its own

“Computer" controlling these functions. In order to access many of these

remotely controlled functions, the user must be in the RESET state to do so.

RESET is entered anytime power to the locomotive has been off for more

than 3 to 5 seconds. When the engine first enters RESET, the

microprocessor initiates a system check to determine if the system,

Premier GP-7/9 Operating Manual

transformer and engine are operating correctly. This takes approximately 5

seconds during which you will hear the engine’s startup sounds begin. In

order for ProtoSounds® to properly initiate the system check, do not

advance the transformer throttle past 10 volts when you first enter RESET,

wait for the diesel startup sounds to begin and then slowly turn the

transformer throttle to the off position and then back on again to enter the

forward phase. Interrupting the power too quickly may cause the system to

re-enter RESET (signaled by two dings of the bell). Should this happen,

wait longer before interrupting the power to enter the Forward phase.

ProtoSounds® comes with several programmable functions, including

Engine Volume Adjustment, Separate Bell Button Operation

(pre-programmed at the factory), Cab Chatter On/Off Control, ProtoCoupler

On/Off Control and Horn-In-Neutral Operation. Each of these features are

described in more detail later. You will notice that when in RESET, your

engine will not respond to the whistle button with a horn blast or continuous

bell ringing. In fact, when in RESET and the whistle button is depressed,

only one single bell chime will be heard each time the whistle button is

pressed. If you don’t want to configure or change your locomotive using

any of these programmable features, simply leave RESET and wait 5

seconds before interrupting the power to put the engine in forward. After

you leave RESET, your engine will operate normally in all the direction

states of forward, neutral and reverse.

HORN OPERATION

Your GP 7/9 ProtoSound® equipped engine is equipped with a digital

recording of a diesel horn. The horn sound can be activated anytime the

engine is in forward or reverse by pressing the whistle button on your

transformer. The horn will continue to blow as long as the whistle button is

depressed. The horn will not function in RESET and must be configured

through a RESET option to allow the horn to work when the engine is in

neutral. See page 17 for information on horn programming in the Using

RESETTo Program ProtoSounds® section of this manual.

BELL OPERATION

Your GP 7/9 ProtoSound® equipped engine is equipped with a digital

recording of an actual diesel bell. Unlike previous versions of

ProtoSounds®, the bell can be turned on or off with any separate bell

button, like the Lionel® Railsounds® No. 5906 Bell Button, by simply

Premier GP-7/9 Operating Manual

pushing the button. If you don’t have a separate bell button, the bell can be

controlled through your transformer’s whistle button whenever the engine

is in NEUTRAL. The bell will never ring continuously in RESET

(Remember NEUTRAL is the state between Forward and Reverse). Once

the bell is turned on, it will continue to ring when the engine is cycled into

forward or reverse until you press the bell button or re-enter NEUTRAL

and turn the bell off with the whistle button.

To turn the bell on using the transformer’s whistle button, turn on power to

the track and cycle the engine into NEUTRAL. Turn the throttle to 8 volts

or less (any higher voltage will arm the ProtoCoupler™) and press the

whistle button. The bell should begin chiming. To turn the bell off, press

the whistle button again. If you want to keep the bell on while running the

engine, simply interrupt the power with the transformer throttle or the

transformer directional switch and enter forward or reverse.

PROTO-COUPLER™ OPERATION

Your GP 7/9 ProtoSound® equipped locomotive has two coil-wound

ProtoCouplers™ for remote uncoupling action. The couplers are mounted

on the power trucks. Because the ProtoCoupler™ is controlled through

ProtoSounds® microprocessor, it doesn’t require an uncoupling track

section or modification to your layout to function. The three simple steps

below are required to operate the coupler.

1. Put your engine in NEUTRAL and turn the throttle all the

way up.

2. Press the transformer whistle button to “Arm" the coupler.

(You will hear a “Clank")

3. After arming the coupler, press the whistle button again to

open the coupler.

And Listen For The

Cha-Chusshh Sound

Premier GP-7/9 Operating Manual

When the knuckle fires open you will hear the buzzing of the coil

energizing and the sound of the air lines coming apart. It can best be

described as a CHA-CHUSHHH sound. The coupler doesn’t have to be

fired in NEUTRAL. Once the

coupler is armed it can be fired

in Forward, Neutral or Reverse.

However, you may find that the

coupler doesn’t open when

firing the coupler at high

speeds. Reduce the voltage

setting on your transformer if

this occurs and run your engine

at a slower speed before firing

the coupler. If the coupler

continues to open erratically, try

lubricating the knuckle with

light oil as indicated in Fig. 3.

For multiple heading purposes, only one of the two ProtoCouplers™ will

function at any one time. Use the coupler direction switch as shown in Fig.

5 on page 16 to select either the front or rear coupler. Simply slide the

switch toward the direction of the coupler you want to make active.

SQUEAKING BRAKE SOUNDS

ProtoSound® equipped engines feature the ability to play the sound of

squeaking brakes whenever your engine slows in speed. There are two

settings for activating the squeaking brake sounds. The default setting

allows the brake sounds to play while the engine is in forward or reverse

and the transformer throttle is lowered from a high setting to a low setting

(14 volts to 8 volts or less). The second setting requires that a bell button be

used to “arm” the brake feature and is explained in more detail in the

“Activating Freight Yard Sounds” section found later in this manual. The

sound itself is a stored record on the ProtoSounds® software chip and will

always play the same brake sound for the same three second length each

Lubricate Coupler Rivet

Throttle Down From

High Voltage To Low

Listen For The

Squeaking Brake Sounds

Premier GP-7/9 Operating Manual

time the voltage is reduced from high to low. Some practice may be

required to synchronize the playing of the brake sounds with the movement

of the engine. It is not uncommon for the engine to stop before the brake

sound is completed. Operators will find that by coordinating the movement

of the throttle setting from 8 volts to off will allow the engine to maintain its

movement while the brake sounds play. Note: The brake sounds will not

be heard if the transformer throttle is not set above 14 volts and/or not

reduced below 8 volts.

TIPS ON USING THE SQUEAKING BRAKE FEATURE

Users will find the squeaking brake feature to be a very realistic way to

simulate the sound of an engine slowing down for curves, crossings or coming

to a stop at a station, side track or switch yard. However, you may find that

your engine continues to play the brake sounds once your engine comes to a

stop, or that the sounds stop before the engine comes to a complete halt. For

example, if you simply run the engine and turn the throttle off quickly, the

brake sounds will likely continue playing even though the engine has come to a

complete stop.

This annoying effect can be eliminated by simply practicing with the brake

feature. In no time, you will quickly learn how to “feather" the throttle to keep

the engine moving while the brake sounds play and then turning the throttle off

just as the sounds stop.

Operating Proto-Sound Freight Yard Sound

Effects

Freight Yard Sounds (FYS)

Proto-Sound® is equipped with operator controlled Freight Yard Sounds,

referred to as FYS. The FYS sequence is designed to simulate the arrival,

unloading, loading and departure of a freight train in a freight yard. This

easy-to-use feature allows you to play digitally recorded sounds of freight

yard operations while your engine is parked in the Neutral State. No

additional wires or modifications are needed to enjoy these amazing sound

effects. The sounds themselves are randomly “shuffled” by the

Proto-Sound® computer. This gives the system the ability to play the

various sounds in a different order each time FYS is enabled.
