M.T.H. Electric Trains®
Z-4000 400-Watt Transformer
Operating Instructions
The M.T.H. Z-4000® Transformer is a state-of-the-art UL-approved 400-watt
model railroad hobby transformer. It features a microprocessor-controlled
interface that provides the model railroader unprecedented control over any AC-
powered model locomotive and locomotive sound system. The Z-4000
transformer may be used alone for local control of a model railroad or it can be
paired with a remote control system, such as the M.T.H. Z-4000 Remote Control
System or the M.T.H. DCS Remote Control System. Operators of any AC
powered O, S, or Standard Gauge locomotive, regardless of manufacturer, will
appreciate the power and control features found in the Z-4000 transformer. For
your own safety and that of your equipment, please read the following pages
before beginning to use your Z-4000 Transformer.
CAUTION-ELECTRICALLY
OPERATED PRODUCT:
Not recommended for children under 10
years of age. M.T.H. recommends adult
supervision with children ages 10-16. As
with all electric products, precautions
should be observed during handling and
use to reduce the risk of electric shock.

The Z-4000 Transformer’s control panel has a voltage display, amperage display,
and horn, bell, direction, and programming buttons for two track outputs. Two
additional fixed voltage outputs are also available, making the Z-4000 the perfect
choice for operating O, S, or Standard Gauge locomotives and accessories.
The Z-4000 was designed to operate any AC-powered model train or operating
accessory. The transformer contains two variable outputs, each capable of
providing 180 watts to the track or accessory, and two fixed voltage outputs of 10
and 14 volts repectively. The fixed outputs are designed for powering accessories
like lamps and switches, while the variable outputs should be utilized for
locomotive and operating accessories. In addition, the Z-4000 features individual
circuit breakers for each output and utilizes a state-of-the-art design that minimizes
voltage fluctuation when bell or horn buttons are activated.
Operating a locomotive or accessory is a
straight-forward process. Voltage output is
controlled by the throttle setting. Adjusting
the throttle setting will control the track
voltage, which is shown on the VOLTS
display. Pressing the DIRECTION,
WHISTLE/HORN and BELL buttons
should cause the locomotive to change
direction, blow its whistle or horn and ring its
bell (if the engine is so equipped),
respectively. It is important to wire up the Z-
4000 to your track correctly in order for the
button function to perform properly. If the
horn or bell does not function when their
buttons are pressed, check the transformer
connections for proper hook ups. The
buttons also perform secondary functions (shown in white letters with blue
background) when the Z-4000 is in Program mode. For more information on
using the buttons, see the “Basic Operating Instructions” and “Programming
Proto-Sound® Features” sections of these operating instructions.
As with all electrically powered products, certain precautions should be taken
before operating the Z-4000 transformer. Please review the precautions section in
the back of this book before operating your Z-4000.
Note: If at any time the red warning light illuminates and stays lit (located on the left side of the
transformer case), the operator must return the throttle handles to the OFF position to reset the
transformer output.

WIRING UP THE Z-4000 TRANSFORMER
The Z-4000 contains connectors that are designed to accept banana jack
connectors or may be used as traditional screw down binding posts at the back of
the transformer case. Each connector is color coded, BLACK for ground (-) and
RED for positive (+) connections. The top row of connectors are BLACK and
act as common ground connections for each output, while the bottom row of
connectors are RED and provide the positive connection for each output.
Connect the BLACK or ground terminal to either outer rail of the track and the
RED or positive terminal to the center rail of the track. Wiring the constant
voltage outputs (used for accessories) follows the same convention.
Once the track and/or accessories have been wired up to the Z-4000, plug the AC
power cord into any 110V household plug and follow the remaining operating
instructions.
Note: The owner should not, at any time, attempt to connect or short any of the voltage outputs
together in an effort to gain more power output. If the user attempts such a procedure, the Z-
4000 may become permanently disabled. At the very least, the Z-4000 will automatically shut
down and the red OVERLOAD light will be illuminated.
Also functions as a binding post.

BASIC OPERATING INSTRUCTIONS
1. Make sure the two large throttle handles located on either side of the
transformer are in the fully lowered (or OFF) position.
2. Turn the Z-4000 on by pressing the Power On button located on the lower right
front side of the transformer case.
3. Displays should illuminate and read approximately 0.0 VOLTS and 0.0 AMPS as
no power to the track will be applied when the throttle handles are in the OFF
position. When the handles are in their fully raised or HI position, approximately
22 volts of power will be applied to the track.
4. Move a throttle handle slightly from the OFF position toward the HI position.
You will see the VOLTS display for the track you are operating show a starting
voltage of approximately 5 volts applied to the track. In other words, the Z-4000
has an effective start-up voltage setting of approximately 5 volts, rather than 1, 2,
3, or 4 volts. This convention follows the design of the Proto-Sound® system and
does not effect the operation of any other manufacturer’s locomotive or accessory.
5. When you are ready to run the locomotive, raise the throttle handle to increase
voltage to the track until the train begins to move. Proto-Sound-equipped and
some other recent locomotives are programmed to begin in neutral, so you will
need to push the Direction button to put these engines into forward. Older
locomotives ma
Note:: If no load is present on the track when power is first applied (by moving the throttle up
from the fully lowered position), the voltage meter will jump to approximately 10 volts. A load is
created if any accessory, lighted car or locomotive is present on the track when power is applied.
No Accidental Startups will occur with the Z-4000 because the variable outputs are protected
from accidental high-power startup. If the throttle handles are not in the OFF position when the
Z-4000 is first turned on, no power will be applied to the track and the red OVERLOAD
light will illuminate.

Operation Buttons:
Horn/Whistle
Bell
Direction
- To sound the horn or whistle, firmly press the Horn/Whistle
button. The longer you hold the button down the longer the horn or whistle will
sound. The horn/whistle will stop when you release the button.
- To sound the bell (if the engine is so equipped), firmly press and release the
Bell/Select button. To turn the bell off, press and release the Bell/Select button
again. The bell will continue to ring from the time your turn it on until you press
and release the button again, to turn it off.
- To change the direction of the train, or to put it in neutral, firmly
press and release the Direction button. (Alternately, you can still change directions
by dropping and restoring power with the throttle handles, as you do with other
transformers) With the reverse units used in M.T.H. and most other model trains,
the direction will not go directly from forward to reverse. If a train has been going
forward, the first press will put the train from forward into neutral, the second
press into reverse, the third press back into neutral, and the fourth back into
forward. Please refer to your locomotive’s operating instructions for more
information.
PROGRAMMING PROTO-SOUND® 2.0 FEATURES
Proto-Sound 2.0 features are triggered by a series of combination signals. You will
press the horn/whistle and bell buttons in certain combinations to trigger each
feature. There is no Program Button operation in Proto-Sound 2.0. Please see
your engine’s operating instructions for the combination signals to operate its
features.

PROGRAMMING ORIGINAL PROTO-SOUND®
FEATURES
Programming While in RESET:
Most of the programming features are accessed from the RESET Mode. When
you first turn on the transformer, Proto-Sound-equipped engines will be in
RESET. You can return to RESET at any point during operation simply by
turning off power to the track (putting the throttle handles into the fully lowered
OFF position) for ten seconds or more. You will hear the sounds of the engines
on that track decrease and a single ding to indicate that it has powered off.
When in RESET, your engine will not respond to the whistle or bell buttons with a
horn blast or continuous bell ringing. If you don’t want to configure or change
your locomotive using any of the programmable features, simply leave RESET by
raising the throttle and wait 5-10 seconds before running the locomotive. After
you leave RESET, your engine will operate normally in all the directions, forward,
neutral and reverse. Remember though, once power is turned off for more than 10
seconds, the next time power is applied to the track, your engine will be back in
RESET.
1. While the engine is off, firmly press the Program button to enter Program
Mode. The amps display will read “PG” to indicate that you have entered
PROGRAM. When in PROGRAM, the transformer’s Bell, Whistle/Horn, and
Direction buttons assume secondary programming responsibilities that make
accessing the RESET features easy. The white lettering on blue background
describes what each button’s secondary function is. Note: While in PROGRAM,
the displays for the other track will be blank and controls will be locked.
2. Use the Whistle/Horn button to scroll up to the desired feature number or the
Direction button to scroll down (see your locomotive’s operating instructions to
determine which number accesses which feature). The feature number will be
shown in the Volts display.
3. Firmly press the Bell/Select button to indicate that you wish to select the feature
number displayed.
4. The locomotive will make air release sounds to indicate what feature number you
have selected (i.e. if you chose feature number six, the air release will sound six
times in rapid succession). This will be followed by a series of
6

clinks and clanks to reconfirm your selected feature number. One clank indicates
the number five and one clink indicates the number one. Hence, feature six will
draw one clank followed by one clink. Feature fifteen, on the other hand, would
draw three clanks and no clinks, and feature twenty-two would draw four clanks
followed by two clinks. The volts window will also display the number you have
selected.
5 .At this point, you can access the specific setting you wish to program in the
chosen RESET feature by firmly pressing the Bell/Select button. See your
locomotive’s operating instructions for directions how to program each feature.
Note: your locomotive’s operating instructions may indicate that you should use
the Whistle/Horn Button to change feature settings. However, in PROGRAM,
the Bell/Select Button does this. The Whistle/Horn and Direction buttons
continue to allow you to scroll up and down between feature numbers.
6. If you wish to program other RESET features, repeat steps 2-5.
7. Once you have finished programming features, press and release the Program
button to lock in your settings and to return the throttle and buttons to their
primary functions. You will know you have successfully exited PROGRAM when
the amps display no longer shows “PG.”
8. When Power is turned back on the Engine will be in RESET.

Programming While in a Direction:
Firmly pressing the Program button while the
transformer is applying power to the track (7.5
volts or more) and the locomotive is in a
direction (Forward, Reverse, Neutral) allows
you to boost power to the locomotive, or to
lockout or unlock directional control of Proto-
Sound-equipped engines. Directions for each
setting are given below.
You can temporarily boost power to the track
(and the engine’s speed) without changing the
commanded track voltage at the throttle.
1. While the transformer is applying voltage to
the track, firmly press and release the Program
button. The Volts display will flash off, then
read “52” and the Amps display will flash off
then read “PG.”
2. Firmly press and hold the Bell Button. The
Volts display will change from “52” to read the
actual track voltage. The track voltage will
increase for as long as the Bell button is
depressed (up to about 25 seconds) and the Z-4000’s
maximum output voltage has not been exceeded.
3. When you release the Bell button, the track voltage
will gradually decrease to the commanded level set
with the throttle.

Locking an Engine into a Direction:
Proto-Sound-equipped engines have a feature that allows you easily to lock the
engine into the direction it is currently running. Before you can do this, the
locomotive’s lock-out feature must be enabled. Most later Proto-Sound-equipped
locomotives are programmed with the lock-out feature disabled to prevent
accidental lock-outs. Please see the operating instructions for your locomotive for
how to enable the lock-out feature.
1. While the transformer is applying voltage to the track, firmly press and release
the Program button. The Volts display will flash off, then read “52” and the Amps
display will flash off then read “PG.”
2. Depress the Direction Button and scroll to feature 50.
3. Firmly press and release the Bell button to start the Lock-Out Macro. At this
point, the Z-4000 will blow the locomotive horn or whistle while reducing the track
voltage to 0.0. Within two seconds of the track voltage dropping, your locomotive
will sound a short blast of its whistle or horn and track power will be restored. At
this point the locomotive will be locked into the direction it was traveling when you
activated the feature. Turning the transformer off and then on again should not
allow the engine to stop and change direction.
4. Note: When locking an engine into Neutral, you must set track voltage below 10 volts. At
this voltage, activation of the Lock-Out Macro may cause the bell to begin ringing rather than
sounding the whistle/horn. This is normal.

In order to Unlock the engine and allow it to change directions, do the
following.
Handle Tension Adjustment
Handle Tension Screws
1. While the transformer is applying voltage to the track, firmly press and release
the Program button. The Volts display will flash off, then read “52” and the Amps
display will flash off then read “PG.”
2. Depress the Direction Button and scroll to feature 51.
3. Firmly press and release the Bell button to start the Unlock Macro. At this
point, the Z-4000 will blow the locomotive horn or whistle while reducing the
track voltage to 0.0. Within three seconds of the track voltage dropping, your
locomotive will sound a ding of its bell and track power will be restored. At this
point the locomotive will be in RESET. Turning the transformer off and then on
again will allow the locomotive to move forward. Operate using the direction
buttons or throttle as usual to change directions.
Your Z4000 includes Handle Adjustment Screws. The
are located on the bottom of the Z4000 with directions so that you may adjust the
tension to your liking.
