MTH SD40-2 Diesel Operating Manual

BATTERY PROBLEMS

REMEDY

I get no sounds when the engine shifts between the

direction states.

The battery may be dead or needs charging. See the

Battery Backup section for more information.

After I turn off my transformer, my engine continues to

make sounds before quitting with a ding of its bell.

ProtoSounds continues to sound for approximately 10

seconds after power to the track has been shut off.

The sounds distort at low voltages.

The battery is insufficiently charged or dead. Follow

the recharging instructions found in the section entitled

“Self Recharging Battery Backup System”.

A repeating horn blast occurs after the power has

been shut down.

The ProtoSound module has detected a problem with

the electronics. Should such a warning occur,

disconnect the battery and contact MTH for return

authorization instructions.

RESET PROBLEMS

REMEDY

When I first turn the power on, the engine will not

begin to run. I have to turn the throttle off and then on

again to get the engine to operate.

This is normal behavior. When power to the track is

first turned on, ProtoSounds enters a “RESET” phase

at which time the engine undergoes a system check.

Power must be interrupted to get the engine into the

Forward Phase. See the section entitled “DCRU

Reverse Unit Operation” for more information.

Whenever I interrupt the power from RESET to enter

Forward, the engine goes back into RESET instead of

Forward. I know this occurs because the bell dings

twice.

Whenever ProtoSounds enters RESET after power

has been off for more than 15 seconds, the

microprocessor initiates a system check to determine

that everything is in working order. This system check

requires 2.2 seconds to complete during which time

the engine will play the diesel startup sounds. We

recommend that you don’t interrupt the power in

RESET until the diesel startup sounds have

completed. This will guarantee that the system check

will have been completed since the startup sounds

take longer than 2.2 seconds to play. If the problem

persists, we recommend that you operate the throttle

with a slower movement as you interrupt the power in

RESET and enter the Forwaard Phase

BRAKE SOUND PROBLEMS

REMEDY

When the transformer is throttled down, the sounds

won’t play.

The brake features has not been activated. See the

section on activating the brake feature for more

information.The throttle voltage setting on the

transformer is either not starting high enough or

ending low enough to trigger the brakes sounds. Try

increasing the throttle setting to 14 volts or higher

before throttling down to 8 volts or less.

The brake sounds continue to play even after the

engine stops.

The brake feature sound record lasts for three

seconds. With practice you can control how quickly

you should stop the engine to keep it in sequence with

the sound of the brake’s squeaking.

The brake feature was activated in neutral after the

engine was running in forward, but the brake sounds

would not play when triggered after the engine went

back into forward or reverse.

The brake feature will only remain enabled if it is

triggered in the first direction state you enter after

activating the feature in neutral. You cannot interrupt

the power twice to enter another direction state and

still have the brake feature active. Therefore, in order

to make the brake sound feature operate in forward,

you must first activate the feature in the neutral

position that occurs after the engine was in the reverse

state.

After triggering the brake sound and stopping the

engine in neutral, the engine begins making freight

yard sound effects.

After you trigger the brake sounds, you cannot stop

the engine in neutral and leave the track power on

without activating the freight yard sounds. If you don’t

want to hear the freight yard sounds after entering

neutral, turn the power off for three seconds to disable

the freight yard sound effects.
