IMPORTANT STEPS FOR A SUCCESSFUL INSTALLATION

I t will be a great temptation to begin connecting wires immediately. Before you install your Sierra sound module, there are some simple precautions you should take.

First, finish reading this Owner’s Manual!

The Sierra circuit board should be handled carefully in a static-free environment. To discharge static electricity, touch a grounded water pipe or bare sheet metal surface before handling the circuit board.

Work in a clean, well lit area on a nonconductive surface. Metal scraps and dirt can get onto

Sierra's circuitry and cause shorts.

Never, ever make connections to the sound module while it is powered. Doing so makes for an accident waiting to happen.

Make sure all electrical connections are insulated. Avoid using electrical tape if possible as it tends to unravel over time. We recommend using heat shrinkable tubing instead.

Never allow the speaker outputs to become shorted together.

Never allow the battery wires to become shorted together.

Do not bend the battery terminals. Doing so may rupture the battery seals and allow corrosive liquids to leak.

Do not exceed the ratings for which the module is designed.

Take your time and have fun!

Tools and Materials You Will Need

In addition to the common hand tools found on most modeler’s workbenches, you should have at your disposal:

Low wattage (under 25 watts!) soldering iron

Rosin Core Solder

X-acto knife

Miniature screwdriver set

Diagonal cutters

High speed motor tool (such as a Dremel)

Double sided tape

Silicone RTV

5-minute epoxy

Optional Items for the Perfect Installation

We also recommend the following items to ease your installation:

Microconnectors

SoundTraxx offers microconnectors to facilitate easy separation of items from the locomotive.

SoundTraxx sells P.N. 810012, an easy to handle 2-pin microconnector. Individual connector pins are also available (SoundTraxx P.N. 810058, 10-pack of micro-mini connector pins) which will allow you to disguise the connecting wires as air and water lines but require great care when reconnecting them so as not to miswire the module.

Wiring Aids

We recommend you use insulative and shrink tubing to insulate your connections. SoundTraxx sells P.N. 810037, which contains an assortment of heat shrink tubing suitable for this purpose and P.N. 810036 which provides a length of Teflon tubing. Electrical tape will unravel with time and is not recommended!

Microbulbs

If you intend to take advantage of the special lighting effects and wish to use 1.5 Volt microbulbs for this purpose, SoundTraxx offers P.N. 810022 with a diameter of 1.3mm. P.N. 810024 has a diameter of 2.2mm for use in larger scales. Both are also available in economical six packs.

Heavy Duty Battery

This heavy duty rechargeable battery (P.N. 810075) provides approximately twice the number of operating hours. It measures 2" X 1.65" X 1.97".

Remote Mounted Volume Control Switch

We also offer a switch which can be used to customize the sound system and control the overall volume of Sierra without accessing the circuit board directly. This switch P.N. 810073 can be mounted in a convenient to reach, but out-of-sight location.

Battery Charging Kit

The Battery Charging kit P.N. 810076, allows Sierra's battery to be conveniently recharged from household current, ensuring that Sierra is ready to go before each operating session. Since the locomotive is stationary during the recharging, it also saves excess wear and tear on the engine and ensures maximum operating time.

Trigger Switches

Trigger switches (P.N. 810074) sense magnets placed in the roadbed, and can be used to activate

Sierra's bell, whistle and hiss effects at predetermined locations on your layout. One trigger switch is required per effect and includes one magnet.

Firebox Lighting Kit

SoundTraxx also offers a firebox lighting kit, P.N. 810071 containing one yellow and one orange

LED, pre-wired and ready to install.

Coupler Sensor Switch

The coupler clank sensor switch is used to trigger the sound of the coupler clank when coupling to a boxcar or another engine.

Speakers

Sierra comes with it's own speaker, usually designed to fit a particular locomotive. Other speaker sizes are available if your particular installation requires a larger or smaller speaker. Remember, larger is always better! See Appendix A.

Step 1. Select your Locomotive

If this is the first time you have installed sound in a locomotive, then we suggest you choose your locomotive carefully. A few simple precautions will ensure that your first effort produces a great sounding locomotive instead of an intimidating ball of wires:

- Do pick a smooth running locomotive that runs well. A smooth running mechanism is vital for good throttle control and enhances the realism of the sound. Dirty, worn out or binding mechanisms will have trouble starting smoothly and will destroy the illusion created by the Auto-Exhaust feature if they barely lurch along at half throttle.

- Do pick a locomotive with a reasonably large, rectangular tender. The larger the tender, the more room you will have for installation of the module, battery and speaker. It will also allow you to use a larger speaker, giving both better volume and sound fidelity.

- Do start with an engine that is ‘sound-ready’ if possible, such as an engine with predrilled speaker holes, for example. The simpler you can make your first installation, the better.

- Don’t pick a noisy engine, or one which experiences some arcing or sparking when in operation. The best sound will come from locomotives powered with can motors. Older, open-frame motors may produce an offensive, interference sound.

Step 2. Plan the Installation

You should give some thought to where the installation of the various Sierra components will be within the locomotive before you get started. Figure 3 shows a typical installation.

The decision most critical to the success of your installation will be where to put the speaker.

Obviously, the ‘where’ of speaker installation will depend on the size and type of the locomotive.

But when considering the speaker’s location, remember that the volume of the speaker will be

6


greatly enhanced when the speaker is fitted into a small airtight enclosure with the front of the speaker open to surrounding air. The reason for this is simple: in order to generate any appreciable sound, the speaker must develop air pressure. Without an enclosure, any pressure developed by the front of the speaker is canceled by an opposite pressure behind the speaker. The enclosure isolates the front and back surfaces of the speaker, thereby increasing the sound pressure and hence, the volume.

Figure 3 - Typical Sound Installation

Additionally, the enclosure must be sized proportionally to the speaker such that the volume of air enclosed is several times larger than the speaker diameter. If an enclosure is too small, it will interfere with the speaker operation and although it cannot be made too large, there is a point of diminishing return. As a rule of thumb, for small speakers, the minimum for the length, width and height should be equal to the speaker diameter. Thus the smallest enclosure for a 3" speaker would be 3" X 3" X 3". As this is only a general guideline, exceptions can and must be made in many circumstances.

HOWEVER, the use of a proper speaker enclosure cannot be over emphasized and failure to use one is almost always the cause for poor sound quality.

Fortunately, most steam engines have a tender and with a little work, the tender itself becomes a great speaker enclosure. The speaker can face up through the coal bunker or down through the floor. Either way will produce equally good sound.

You will also want to use the largest speaker possible to get the best bass response. Larger diameter speakers can be trimmed down in width so they will fit within the tender shell. By building an internal baffle, they can also be mounted at an angle although this may compromise the available space for the Sierra sound module in all but the largest of tenders.

In small tenders, the speaker should be mounted forward in the coal bunker area, where higher walls are available to cover the speaker magnet.

For other locomotives, the speaker enclosure need not be fancy and can be fabricated from sheet styrene, bass wood, and even cardboard in a pinch! The cardboard tube center of a roll of paper towels usually produces excellent results.

The Sierra sound module is best suited for installation in the tender, although it will fit in the boiler of larger locomotives. Boiler installation has the advantage of requiring considerably less wires that have to be routed between the engine and tender. It will usually come at the expense of some boiler weight and possible reduction in traction.

It is normal for the Sierra module to get warm after periods of extended operation and its built-in thermal overload protection will automatically shut down the audio amplifier if it gets too warm.

Therefore, it is important to install Sierra in a location where it can dissipate the most heat. Avoid placing the module near heat sources such as the motor or lights.

You will also need to decide how you will synchronize the exhaust chuff. SoundTraxx Sierra provides two means for synchronization. The first method is to use a magnetic sensor switch in conjunction with 2 or 4 magnets mounted on an axle or the inside face of a driver wheel. As the wheel rotates, the magnets pass by the sensor switch, producing a chuff.

This will give the most precise synchronization and even produce a wheel slip effect if the locomotive is accelerated too quickly! In a pinch, the magnetic sensor switch can be used with a tender axle, although the synchronization effect will not be exact unless the tender wheel diameter is an exact multiple of the locomotive driver diameter.

The other method of exhaust synchronization is Sierra’s Auto-Exhaust feature which produces chuffs in proportion to the throttle setting. This method is recommended for those locomotives where the magnetic sensor would be difficult to install.

Next, you will need to consider which lighting effects you will use. Sierra provides for two lighting outputs which can be used for controlling lightbulbs or LEDs.

The outputs may be customized as follows:

· As a conventional on/off output, they may drive additional bulbs for a constant intensity headlight, cab light, marker lights or number boards.

· As a Mars light, they may be used to simulate the famous warning beacon found in front of the modern steam engines used by railroads such as the Southern

Pacific, Union Pacific and Nickel Plate Roads.

· As a firebox light, they may be used to simulate the flickering glow from the firebox.

· As a 'smart' firebox light, they may be used to produce a firebox flicker effect that turns on only when the sound of the firebox door opening has been activated and turns off when the doors “close”.

Each Hyperlight output can be independently programmed so it is possible to use one output as a Mars light and the other bulb for the firebox.

Finally, you will need to consider installation of any of Sierra's optional accessories such as the charging jack, coupler clank sensor switch, etc.

After you have fully read the installation manual, we suggest reviewing Step 10 on wiring the module and draw yourself a schematic similar to Figure 3 showing all connections between Sierra and the various subcomponents. This will also help you determine which connector is best suited for your needs, should you decide to use one.

Step 3. Modify the Tender Body and Floor

Depending upon your choice of tender, you will probably be mounting the speaker facing down on the tender floor or facing up in the coal bunker. In either case, a certain amount of “body work” may be necessary to accommodate the speaker, battery and sound module. This may include removing weights, mounting brackets, internal bracing and other structural features.

Although some models come with speaker holes predrilled, in other locomotives you may need to cut an opening in the tender shell or floor for the speaker. A series of small holes can be easily drilled and will work as well as one large hole provided the open area is at least one half the area of the speaker cone. In either case, there should be no openings outside or larger than the


speaker cone itself.

Tender Body Modifications

On tenders with low side walls, the speaker is often best mounted facing up in the coal bunker so as to provide adequate clearance for the sound module which will be mounted against the tender floor. In some cases, it may even be necessary to add a wooden “retaining wall” to build up height.

The simplest tenders have a flat deck across the coal bunker and are the easiest to deal with.

Simply mark or scribe the speaker outline onto the tender deck and using a jeweler’s saw, cut out a circular opening about 1/16" inside the outline marks. Remove all sharp edges and burrs. The speaker is then disguised by covering the opening with a acoustically transparent coal load. The coal load can be fabricated by contouring a piece of fine screen mesh or polyurethane foam to represent a coal load and then covering it with a thin layer of scale coal cemented in place with a thin wash of diluted white glue.

Remove inside walls and slope sheet if needed.

Cut hole diameter to slightly less than speaker diameter.

Perforate coal load with #55 drill.

Styrene in sub-deck

Cross section of plastic tender with molded coal load.

Optional wooden retaining boards to build up height.

Opening in deck should be slightly smaller than speaker diameter

Figure 4 - Tender Shell Modifications

Plastic tenders often have a molded coal load already in place. Unfortunately, the inside surface of such tenders are contoured to match the coal load and do not provide a flat mounting surface for the speaker. In such cases, the modeler has two options. The first is to cut out and remove the coal load entirely and replace it with a flat sheet of 0.060" or thicker styrene and then proceed as described above for the flat decked tenders.

Alternatively, a sub-deck can be fabricated from 0.060" sheet styrene such that it fits below the coal load tightly against the tender sides. Cut a large circular opening appropriate for the speaker diameter into the styrene sheet and then glue the sub-deck to the inside of the tender shell. Perforate the coal load by drilling a series of small holes (use a #50-#60 drill) at random angles between the coal “nuggets”. This way, the sound will be allowed to escape yet the speaker remains relatively invisible regardless of viewing angle.

The more realistic tenders will have fuel bunkers that prototypically extend to the tender floor. For


9

larger tenders with such a feature, the speaker is best mounted on the tender floor. For smaller tenders, the slope sheet and interior walls will interfere with the speaker and it will usually be necessary to remove and replace them with sheet brass or styrene to create a flat decked tender.

Tender Floor Modifications

If you are mounting the speaker to the tender floor, first determine the exact speaker location within the tender and verify that there is adequate clearance between the tender body and speaker magnet. Use a marker or scribe to note the location of the speaker on the tender floor and then drill three rows of holes (see Figure 5) in the pattern shown to provide an opening for the sound to escape. A drill approximately .250" is a good size. Space the holes as best you can, taking into consideration the tender underbody detail. Although the spacing is not critical, you should attempt to provide at least this much of an opening. If necessary, use more holes of a smaller diameter. Keep all the holes within the expected cone area of the speaker. Take care not to place holes at the outer edge of the speaker assembly itself.

Once you have drilled your holes, remove all burrs and uneven edges. Make sure there are no metal burrs or edges projecting up - the speaker floor should be smooth, with nothing to physically interfere with the speaker’s ability to lay completely flat on the tender floor, such as solder joints, screw bosses, and mounting studs.

Secure the Speaker in Place

Once body work is complete and the speaker has been fitted in place, it must be secured tightly to the enclosure. For the best sound, an airtight seal is needed around the speaker edge and we have found the best way to hold the speaker in place is to use silicone RTV - it provides the airtight seal needed and unlike epoxy or other hard glues, allows the speaker to be readily removed in the future. Be careful that you don’t get any RTV onto the speaker cone itself as this will severely distort the sound quality!

Step 4. Install the Power Switch

Select a discreet but easy to access location for mounting the power switch. Drill a 1/4" diameter hole for the switch and secure with the included nut and washer. Remember to insulative the switch on brass locomotives!

Step 5. Install the Lighting Effects (Optional)

Headlights, Backup Lights and Mars Lights

Drill out the headlight castings to accept any lights you intend to use, including the tender backup light. If you are using SoundTraxx’s 1.5V, 1.3mm microbulbs, P.N. 810022, a #53 twist drill makes a perfect hole. If you are using the larger, 2.5mm microbulbs, P.N. 810024, a #41 twist drill works well.

Test fit the microbulb for adequate hole clearance and enlarge the hole if necessary. Next, paint the headlight castings’ reflector surface with white or silver paint and allow to dry.

Install the light bulbs and secure in place using tape or a flexible glue that does not bond well to

10


glass such as white glue, rubber cement or RTV. Epoxy or ACC glues will make bulb replacement very difficult and are not recommended.

As a final touch, install a lens using white glue to hold it in place. You may wish to use a commercially available lens such as those offered by MV Lenses or make your own. A lens can be easily fabricated from a sheet of clear styrene or alternatively, molded from a drop of clear epoxy that is allowed to flatten and harden on a non-stick surface.

Firebox Lights

The Firebox Lighting Kit comes with a pair of pre-wired orange and yellow LEDs. The firebox lights should be mounted between the locomotive frame rails in the general vicinity of the ash pan. The idea is that the LEDs are never directly visible but rather casts a gentle glow into the cab or onto the ground below if mounted in the ashpan. The LEDs may be held in place with tape or silicone RTV.

If you are using the Smart Firebox Flicker effect, you may wish to modify the locomotive’s firebox door so it is slightly open and then mount the LEDs directly behind it. In this manner, when Fireman Fred puts a few scoops of coal into the fire, the cab will fill with a soft orange glow.

Step 6. Install the Magnetic Sensor Switch (Optional)

If you are intending to synchronize the steam exhaust chuff directly to the drive wheels, you will need to install the magnets and reed switch which come with your Sierra sound system. Otherwise, if you are planning to use Sierra’s Auto-Exhaust feature, you may skip this step.

Begin by selecting the magnet pattern appropriate for your engine. For conventional 2 cylinder engines, four chuffs per wheel revolution is prototypically correct. However, keep in mind that most large scale trains are run faster than scale speeds and using 4 magnets per axle revolu-

tion is probably not going to give the desired results.

Conventional Articulated

We find that using 2 magnets per axle will produce a more pleasing sound. Sierra is supplied with two magnets; additional magnets can be purchased from SoundTraxx as

P.N. 810095 or Radio Shack

P.N. 64-1895.

Articulated Steam Locomotives

Articulated engines come in two flavors, simple and compound. On simple articulated engines, the cylinders on the front and rear are the same size. On compound engines, one set of cylinders is considerably larger than the second set.

For compound articulated engines, 4 chuffs per driver revolution is correct. Install the same as for regular locomotives. For simple articulated engines, spacing the magnets unevenly will provide an 'interesting' exhaust cadence.

Geared Locomotives

Geared engines require a larger number of chuffs due to multiple cylinders and gearing of the drive wheels. Due to the large number of contacts required for each wheel revolution, it is usually impractical to achieve the prototypically correct number of exhaust chuffs per revolution. It is usually preferable to use the Auto-Exhaust feature.

Install the Magnets

The magnets may be mounted to the axle or locomotive drive wheel. First, trial fit the magnets


11

for adequate clearance between the wheel and the locomotive frame. Space the magnets as far apart as possible, but do not locate them so close to the edge of the wheel flange that they cause interference with track features such as guard rails and turnout frogs. Once you are satisfied with the magnets' location, they can be secured in place with 5-minute epoxy.

Install the Sensor Switch

Caution: The switch sensor is made of glass and can be broken if mishandled. Do not bend the sensor's leads or make solder connections within 1/8" of the glass body. If you do need to bend the leads, hold the lead with a pair of needle-nose pliers between the switch body and the bend point. Then bend the lead as needed. Solder connections should be made as far from the switch body as possible using only a minimal amount of heat.

The magnetic sensor switch should be installed so that it floats 3/8" or less from the surface of the magnet. You will probably want to attach the black connecting wires before installing. Cut the black wire in half and strip and tin each end. Solder one wire to each lead of the sensor switch.

Once the leads are attached, temporarily mount the sensor switch in place with adhesive tape.

Once your system is wired, you may find that the sensor's location will have to be adjusted to get reliable pickup.

Once you are satisfied with the switch location, permanently attach it using 5-minute epoxy.

Reed switch should be 3/8" or less from magnets as shown

Mount one magnet on each side of axle

Mount magnets on inside of driver wheels

Reed switch should be 3/8" or less from magnets as shown

Figure 6 - Magnet and Sensor Installation

Step 7. Install the Coupler Clank Sensor Switch (Optional)

If you wish to take advantage of the coupler clank sound effect, you have a little more work to do! Otherwise, you may skip this step.

In order to use the coupler clank sound effect, you need to install the coupler sensor in such a way that the switch is depressed when you actually couple to a car or other engine. To do this, you need to modify the coupler so that there is some forward/backward movement. Although there are many different couplers, the principle for installation is the same. Following Figure 7, remove the coupler and elongate the mounting hole with a small round jewelers file so that the coupler will now move slightly back and forth. Take a moment to also remove any burrs that might interfere with movement. Reattach the coupler and tighten the mounting screw just to the point where it contacts the coupler shank. A small metal washer between the screw and the coupler will ensure that the coupler stays in place. The coupler must move easily and be free of binds. A dry graphite lubricant will also help free up sticky couplers.

Mount the switch so that when the coupler is moved back towards the tender, the switch is depressed and when it is moved away from the tender, no contact is made. You can epoxy the switch in place or use the mounting tab and a small screw.

It's nice to mount the switch on the underside of the coupler where it can't be seen, although the

12


switch may be mounted on top if necessary. Drill a small hole in the tender floor for the coupler sensor wires to pass through.

Remove screw and file hole about 1/16" as shown

Mount Coupler Clank Sensor so that switch will depress when coupler is moved

Figure 7 - Modifying the Coupler

Step 8. Install the Charging Jack (Optional)

The optional battery charger allows Sierra's battery to be conveniently recharged without having to run your train. To use the battery charger you must first wire the charging jack into the battery wire harness. Referring to Figure 8, cut the battery wire harness in half and strip the insulation from the ends of each wire. Connect and solder the two black wires to the jack's

A terminal.

Connect and solder the red wire from the battery to the jack's B terminal. Finally, connect and solder the remaining red wire to the jack's

C terminal. Insulate the soldered connections to prevent accidental shorts.

Figure 8 - Installing the Charging Jack

The jack should be mounted in a discreet but convenient location such as under a water hatch and will fit into a 1/4" diameter hole.

Caution: The jack must be mounted to a nonconductive surface as the mounting nut is also the sound system's ground. Do not mount the jack directly to the body of a brass or metal locomotive as a short circuit may result. For such locomotives, you will need to fasten the jack to a bracket or panel fashioned from a nonconductive material such as sheet styrene.

Step 8. Install the Remote Mounted Volume Control Switch (Optional)

The Remote Mounted Volume Control Switch will allow you to customize the sound effects and adjust the volume of the sound system from outside the locomotive. The switch should be mounted in a discreet but accessible location such as underneath the tender. Drill a 1/4" hole at the desired location, insert the switch and thread the switch's mounting nut in place.

Begin by determining the placement of the sound module. Keep in mind that you want to be able to have easy access to the two buttons, LEDs and the battery connector. Once you have determined the optimum location, secure the board in place using double sided foam tape. Be sure the board cannot come into contact with metal or other conductive surfaces. Temporarily refit the body shell to ensure that adequate clearance still exists.

Wiring the sound module is done by way of two terminal blocks on the circuit board. Simply loosen the screw on the top of the block, insert the stripped end of the wire, tighten the screw and your connection is made! When wiring the sound module, trim all wires to reduce unnecessary lead length. This will not only give your installation a neater appearance but also prevent wires from interfering with the drive mechanism and getting pinched between the frame and body shell.

Figure 9 - Master Wiring Diagram

Referring to the master wiring diagram (Figure 9), begin with the speaker connections.

BE ABSOLUTELY SURE THAT THERE ARE NO SHORT CIRCUITS.

Speaker Connections

1. Connect one speaker wire to terminal 9 and the other speaker wire to terminal 10.

Lighting Outputs (Optional)

Each Sierra is equipped with two function outputs that are intended to drive headlight, backup light or special effect lights. Each output is rated for 100mA.

Do not exceed this rating!

To wire the optional firebox lights (P.N. 810071):

1. Connect the RED wire of each light to terminal 4.

14


2. Connect the BLACK wire of one light to terminal 5.

3. Connect the BLACK wire of the other light to terminal 6.

The Sierra lighting outputs may be used with 6 volt incandescent lamps, 1.5 volt microbulbs or

LEDs. If you are using Sierra to drive 6V lamps, each bulb can be directly wired to the effect outputs as shown in Figure 10.

If you are using Sierra to drive 1.5V microbulbs, you need to wire a small current-limiting resistor in series with each of the lamps to prevent them from burning out. A 300 ohm, 1/4W resistor is recommended for use with SoundTraxx P.N. 810022 or 810024 microbulbs, however, you may need to adjust this value to get the desired brightness. Lower resistances will increase the brightness of the lamp.

Sierra may also be used with LEDs, which also require a resistor, typically about 1/4W, 220 ohms.

Note that LEDs are sensitive to polarity.

Note: LEDs are not recommended for use with the Mars Hyperlight effect.

If you have installed the Auxiliary Volume Control Switch, wire it as follows:

1. Connect the switch's BLACK wire to terminal 2.

2. Connect the switch's YELLOW wire to terminal 1.

3. Connect the switch's GREEN wire to terminal 3.

Coupler Clank Sensor Switch (Optional)

If you have installed the Coupler Clank Sensor Switch, wire it as follows:

1. Connect one switch wire to terminal 16.

2. Connect the other switch wire to terminal 12.

Sound Effect Trigger Switches (Optional)

The Sound Effect Trigger Switches are wired between terminal 12 and terminals 13-15, depending on which sound effect you want activated:

1. For a 5-second bell, connect a Trigger Switch between terminals 12 and 13.

2. For a grade crossing whistle, connect a Trigger Switch between terminals 12 and 14.

3. For a cylinder blowdown, connect a Trigger Switch between terminals 12 and 15.

Track and Battery Connections

Caution: Do not perform this step until you have first reviewed the previous steps and double checked your wiring! Be sure Sierra is securely mounted and there are no wire scraps or other debris on the circuit board.

The power switch should be wired into the battery wire harness at this time. After a period of inactivity, Sierra will automatically shut itself down to conserve power; however, it will continue to put a slight drain on the battery and will eventually discharge it. The power switch will allow you to completely cut power to the sound

4. Plug the battery's three-pin connector into the socket on the Sierra circuit board.

Caution: Use your finger to hold the socket firmly against the circuit board when plugging in the connector to prevent the socket from ripping off the circuit board. The connector goes in one way so check that it is aligned properly before plugging it in. It is a snug fit and once plugged in, it is difficult to remove. If it is necessary to remove the connector later, use one finger to hold the socket firmly against the circuit board, while using your other hand to grasp the connector and gently wiggle it from side to side as you pull the connector straight out. Be very careful as excessive force may pull out the wires or rip the mating connector off of the circuit board.

Using Sierra with DCC or an RC Receiver

Sierra can be set up such that the whistle, bell and cylinder blowdown sound effects may be controlled remotely using Radio Control or as an auxiliary function using a Digital Command

Control (DCC) decoder. These installations require additional effort that is beyond the scope of this manual. Technical Note 6 describes how to interface Sierra to a typical Radio Control system such as the Aristo Train Engineer or Locolinc. Technical Note 7 describes how to wire Sierra to a typical DCC decoder. Both bulletins are available free upon request.

Step 10. Test the Installation

Before you close up your locomotive, turn on power to the Sierra circuit board. You should observe the F1 and F2 LEDs light up and hear the firebox box and airpump sound running in the background for a few seconds and then turn back off. If nothing happens, the battery is most likely in need of recharging first (see page 29).

Now you are ready for the test track. We recommend your test track be fused with a fast-blo fuse appropriately rated for your locomotive. Place the locomotive on the track and slowly turn up your throttle to about 1 volt or so. If all is well, you will hear the firebox blower and airpumps running in the background. If there is no sound, double check your wiring to the track pickups.

As you turn up the throttle further to about three volts, you will hear the dynamo spool up and two short whistle toots and then the bell will start ringing. The fire box lights should now be glowing brightly. As the locomotive begins moving you should hear the exhaust chuffs if you have installed the exhaust sensor switch. Otherwise, you will need to complete the setup section to activate the exhaust sound. Tap the coupler sensor switch (if installed) and you will hear the sound of couplers coming together.

This completes the basic checkout. If you are having problems, the troubleshooting section lists common ailments and likely cures.

Step 11. Customizing the Locomotive Sounds

The final installation step (At last!) is customizing the Sierra module’s locomotive sounds. Individual properties such as sound volume, bell ring rate, exhaust synchronization and much, more can be adjusted to suit your needs.

Sierra has been shipped pre-programmed so you can begin using your locomotive immediately without requiring any adjustments.

Table A summarizes Sierra’s default operating characteristics as shipped.

Table A. SoundTraxx Sierra Default Operating Characteristics

Audio Volume = 50%

17

After awhile, you will probably want to make some adjustments, such as changing the voltage at which the bell will turn on and off. The following paragraphs describe Sierra's customizable sound options.

Once the adjustments have been made, they will be permantently remembered even after the power has been turned off. Sierra can be modified as often as necessary by simply reprogramming it according to the instructions.

12 adjustments you will be aided by the use of the two LEDs, labeled in the illustration as F1

(GREEN) and F2 (RED).

Volume (+) Volume (-)

Volume Adjustment

The two buttons usually serve as the master volume control. Press and release the Volume

(+) button and the overall volume of the sound will increase by one level. Press and release the

Figure 13 - Customizing Sierra

Volume (-) button and the overall volume will decrease by one level. There are 16 volume levels.

If you installed the remote volume control switch, simply flip it one way to increase the volume and the other way to decrease the volume.

In Operations Mode, the LEDs indicate whatever lighting effect has been selected.

Setup Procedure

The Setup Procedure is used to customize the different sound and lighting effects. During the setup procedure, you will have both visual (by way of the LEDs) and audible cues to help you through the process. Take your time reading through the setup process first, as there are 20 different items which can be customized and it can be intimidating if you let it. Take your time! Everything can be done or undone and our Reset allows you to start over if you get lost the first time through.

Remember, once you have the sound customized the way you want, Sierra will remember the settings, so you won't have to do it again unless you want to change something.

To activate the Setup Mode press and hold the Volume (-) key until you hear a short toot and the

F1 LED blinks. Then release the (-) key and proceed to Step 1.

Sierra allows you to go directly to a particular Setup Step if you wish (i.e., this morning you wish to turn off the dynamo). Hold the Volume (-) button down, until the number of toots and blinks corresponds to the Setup Step number. In other words, if you hold the Volume (-) button until you hear 6 short toots, while the LED blinks 6 times, you will have reached Setup Step 6 (see

Figure 13). Once the desired Setup Step has been reached, the Volume (-) button should be released. Changes are now made using the Volume (+) button. Once the changes have been made, pressing the Volume (-) key once will lock your changes into memory and returns you to operations mode. Sierra will also exit the setup mode if no key has been pressed for 60 seconds.

If you have installed the optional remote volume control switch, you may also use it to make the sound adjustments by holding the lever in the Volume (-) position until you get to the desired step, and then flipping the lever to the Volume (+) position to make changes.

Before you get started ,we suggest you use a checklist for how you want the locomotive to sound and use it as a reminder as you go along. We've provided one for you at the rear of this manual

18


(see Appendix B). Read through the following steps first, determining those items that you wish to customize and making notes on the checklist.

Now that you are armed with your checklist, let's start to customize our locomotive sounds!

Exhaust Features

Take a look at your checklist and Setup Step 1. The default for this Step is sensor switch synchronization. If you wish to use the Auto-Exhaust instead, you must change this parameter.

Setup Step 1 - Synchronization Source

To change the synchronization source to Auto-Exhaust, enter Setup Mode Step 1, by pressing and


19

holding the Volume (-) key until F1 blinks once and you hear a short toot. Release the Volume (-) key. Press the Volume

(+) key to select Auto-Exhaust. Pressing the Volume (+) again will toggle between sensor switch synchronization (F2 LED

F1 LED: Blinks 1X every two seconds

F2 LED: On = Exhaust Sensor Switch (default)

Off: = Auto-Exhaust

Volume (+) to change

on) and Auto-Exhaust (F2 LED off). If this is the only parameter you wish to change, simply press and release the Volume (-) key. If you wish to make other changes, press and hold the Volume (-) key for 2 seconds until you hear a short toot signifying that you have entered the next programming step, in this case Step 2. Release the Volume (-) key and make your changes with the Volume (+) key as outlined in Setup Step 2, below.

Setup Step 2 - Exhaust Type

This allows you to change the type of exhaust between Conventional Exhaust and Articulated Exhaust. The default value is Conventional Exhaust. This should be used for all engines (including shays) other than articulated. From within Setup

Step 2, press the Volume (+) key. This will


F2 LED: On = Conventional Exhaust (default)

Off = Articulated Exhaust

Audio Cue: Exhaust Chuffing


select Articulated Exhaust. Pressing the Volume (+) key again toggles between Conventional

Exhaust (F2 LED On) and Articulated Exhaust (F2 LED off). Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 3.

Setup Step 3 - Start Voltage

This sets the track voltage level at which point the locomotive begins to move so that the Auto-Exhaust mode can determine when chuffing should start. If you have elected to use sensor switch synchronization, you can skip this step.

The current start voltage setting can be


F2 LED: On = Track voltage at program value

Flashing = Voltage > program value

Off: = Voltage < program value

Audio Cue: None

Volume (+) to set at current level

visually verified by turning up the throttle and noting the point at which the F2 LED begins to flash. This is where the voltage is greater than the currently programmed value. If the LED goes out , the track voltage is less than the current value. The start voltage is set by increasing the throttle to the point where the locomotive just begins to move and the pressing the Volume (+) key. This sets the start voltage to the present level. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 4.

Setup Step 4 - Chuff Rate

This allows you to change the rate of the exhaust chuff. If you have elected to use magnetic sensor switch synchronization, you can skip this step. With the locomotive running, press the Volume (+) key until the rate of the chuff increases to the


F2 LED: Flashes at exhaust chuff rate

Audio Cue: Exhaust chuff

Volume (+) to increase

Volume (-) to decrease

appropriate rate for your locomotive.

Because this adjustment can take a few seconds to set up, the 60 second auto-exit will not be activated as long as there is more than 1 volt on the track. Using the Volume (-) key will decrease the rate of chuff while in this mode. To save your selection, decrease the throttle to less than 1

20


volt. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 5.

Foreground Sound Effects

Setup Step 5 - Bell Ring Rate

This allows you to adjust the bell's ring rate. Press the Volume (+) key to cycle through the available ring rates. Faster


F2 LED: Flashes at programmed ring rate

Audio Cue: Bell ringing


ring rates will simulate an air rung bell, while slower rates are appropriate for a hand rung bell. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 6.

Setup Step 6 - Airpump Type

This allows you to select single or dual airpumps, or to turn the airpumps off. The airpump effect will play the characteristic

'whump, whump' of the air compressor used to build up air pressure in the brake lines. Just like in the prototype, the pump


F2 LED: On = Single airpump (default)

Flashing = Dual airpump

Off =Airpump off

Audio Cue: Airpump


rate will automatically subside over time as "pressure" is built up in the air reservoirs. Heavy brake pressure will cause the airpump to speed up.

Pressing the Volume (+) button cycles through the available options. As you press the Volume (+) key, you will hear the selected airpump. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 7.

Background Sound Effects

Setup Step 7 - Pop Valve

This allows you to enable or disable the

Pop Valve effect. Pressing the Volume (+) key toggles between enabling the Pop

Valve (F2 LED and Pop Valve sound on) and disabling the Pop Valve (F2 LED and Pop Valve effect off). Once you have


F2 LED: On = Pop Valve (default)

Off = Pop Valve off

Audio Cue: Pop Valve sound


made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 8.

Setup Step 8 - Fireman Fred

This allows you to enable or disable the effect of the fireman shovelling coal, or more fondly Fireman 'Fred". Press the Volume (+) key. Pressing this button toggles between enabling Fireman Fred (F2 LED


F2 LED: On = Fireman Fred (default)

Off = Fireman Fred off

Audio Cue: Fireman shovelling coal


and shovelling sound on) and disabling

Fireman Fred (F2 LED and shovelling effect off). Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed


to Step 9.

Setup Step 9 - Grease Gun

This allows you to enable or disable the effect of the fireman using the pneumatic grease gun. When enabled this effect will randomly turn on when the locomotive is sitting idle for a period of time. The default


F2 LED: On = Grease gun (default)

Off = Grease gun off

Audio Cue: Pneumatic grease gun


is to have the grease gun effect enabled. Press the Volume (+) key. Pressing this button toggles between enabling the grease gun (F2 LED and grease gun sound on) and disabling the grease gun (F2 LED and grease gun effect off). Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 10.

Setup Step 10 - Blower

This allows you to enable or disable the effect of the blower draft effect. The

background blowers will always be on as with the prototype. Press the Volume (+) key. Pressing this button toggles between


F2 LED: On = Blower draft (default)

Off = Blower draft off

Audio Cue: Blower draft


enabling the blower (F2 LED and blower sound on) and disabling the blower (F2 LED and blower effect off). Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for

2 seconds until you hear a short toot and proceed to Step 11.

Setup Step 11 - Dynamo

This allows you to enable or disable the effect of the dynamo. Press the Volume

(+) key. Pressing this button toggles between enabling the dynamo (F2 LED and dynamo sound on) and disabling the dynamo (F2 LED and dynamo effect off).

Once you have made the adjustment,


F2 LED: On = Dynamo (default)

Off = Dynamo off

Audio Cue: Dynamo sound


press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 12.

Lighting Effects

Setup Step 12 - Lighting Effect 1

The Effect 1 lighting output can be adjusted to be a constant intensity headlight, a Mars Light, a firebox light or our 'smart' firebox light. The Smart Firebox Flicker effect works in conjunction with the Fireman Fred effect. Press the Volume (+) key.

Each time you press, you will step to the


F2 LED: On = Constant intensity

Pulsing = Marslight

Flicker = Firebox flicker

Dim Flicker = Smart Firebox (default)

Audio Cue: None


next selection. With the F2 LED constantly on, this indicates the constant intensity lighting output is selected. The Mars Light will pulsate towards you and then away, while a bright flicker indicates the always-on firebox light.

Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 13.

Setup Step 13 - Lighting Effect 2

The Effect 2 lighting output can be adjusted to be a constant intensity headlight, a Mars Light,

22


a firebox light or our 'smart' firebox light, just as Effect 1. Press the Volume (+) key.

Each time you press, you will step to the next selection. Once you have made the adjustment, press and release the Volume

(-) key to exit or press and hold the Volume

(-) key for 2 seconds until you hear a short toot and proceed to Step 14.


F2 LED: On = Constant intensity

Pulsing = Marslight

Flicker = Firebox flicker (default)

Dim Flicker = Smart Firebox

Audio Cue: None


Selecting Triggered or Controlled Sound Inputs

Some sound effects have the option of being triggered by changes in the throttle voltage, by sensor switch inputs or a combination of the two.

Setup Step 14 - Whistle Control Method

This allows you to select whether to trigger the whistle by way of the track voltage or by way of sensor switch inputs. In both the voltage and trigger modes, whistle signals are provided for Stop,

Reverse and Forward, whichever is appropriate to the movement of the locomotive. In the voltage control mode, the grade crossing whistle can be activated by momentarily raising the track voltage

or by activating the optional magnetic sensor switch. In the trigger mode, only the magnetic sensor can trigger the grade crossing whistle.

The switched mode would be used if you elected to activate the whistle by way of a radio control circuit or DCC decoder. The


F2 LED: On = Voltage control (default)

whistle will then be activated whenever the whistle switch input is connected to ground. In this case the whistle duration

Flashing = Sensor switch as trigger

Off = Sensor switch as control

Audio Cue: Whistle


is directly related to how long the switch contacts are closed.

The default is to have the voltage control the whistle sounds. Press the Volume (+) key. Pressing this button toggles between available selections. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 15.

Setup Step 15 - Bell Control Method

This allows you to select whether to trigger the bell by way of the track voltage or by way of sensor switch inputs. The bell can be activated by setting a voltage threshold which activates and deactivates the bell.

This is done in Step 17 and 18. Step 15 merely chooses the method of activation.

If you decide to use the trigger mode, a





Audio Cue: Bell


magnetic sensor can trigger the bell, which will ring for about 5 seconds. Keep in mind that if

you choose the trigger control method, this will be the only time the bell is activated. If you wish to be able to activate the bell by trigger or by track voltage, select the voltage control method.

The switched mode would be used if you elected to activate the whistle by way of a radio control circuit or DCC decoder. The bell will then be activated whenever the bell switch input is connected to ground. The bell will ring until the switch input is once again connected to ground, when the bell will turn off.

Press the Volume (+) key. Pressing this button toggles between available selections. Once you


23

have made the adjustment, press and release the Volume (-) key to exit or press and hold the

Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 16.

Setup Step 16 - Hiss Control Method

This allows you to select whether to trigger the cylinder blowdown or hiss effect by way of the track voltage or by way of sensor switch inputs. In the voltage mode, the hiss can be activated by bringing the engine to a stop or by activating the magnetic sensor. In the trigger mode, only





Audio Cue: Hiss


the magnetic sensor will cause the hiss to sound. The switched mode would be used if you elected to activate the hiss by way of a radio control circuit or DCC decoder. The hiss will be activated whenever the hiss switch input is connected ground. In this case the hiss will turn on and continue until the switch input is released, when the hiss will turn off.

Press the Volume (+) key. Pressing this button toggles between available selections. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the

Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 17.

Setup Step 17 - Bell On Voltage

This sets the voltage level for when the bell will turn on if you are using the voltage control method. If you have selected some other method for activating the bell, you can skip this step. The current voltage setting can be visually verified by turning up the throttle and noting the point at




Off = Voltage < program value

Audio Cue: Bell

Volume (+) to set to current level

which the F2 LED begins to flash. This is where the voltage is greater than the currently programmed value. The bell will ring at this point.

If the LED goes out , the track voltage is less than the current value. The bell on voltage is set by increasing the throttle to desired speed where you want the bell to turn on and the pressing the

Volume (+) button. This sets the bell on voltage to the present throttle setting. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume


Setup Step 18 - Bell Off Voltage

This sets the voltage level for when the bell will turn off if you are using the voltage control method. If you have selected some other method for activating the bell, you can skip this step. The current voltage setting can be visually verified




Off = Voltage < program value

Audio Cue: Bell

Volume (+) to set to current level

by turning up the throttle and noting the point at which the F2 LED begins to flash. This is where the voltage is greater than the currently programmed value. The bell will ring at this point. If the LED goes out , the track voltage is less than the current value. The bell off voltage is set by increasing the throttle to desired speed where you want the bell to turn off and the pressing the Volume (+) button. This sets the bell off voltage to the present throttle setting. Note that the bell off voltage cannot be set lower than the bell on voltage set in Step 17. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 19.

Setup Step 19 - Whistle Sensitivity

This allows you to adjust how sensitive the whistle is to changes in voltage when using the voltage method of activating the


F2 LED: LED blinks sensitivity setting



whistle. The greater the sensitivity, the smaller the voltage fluctuation is required to blow the whistle. If you have selected some other method for activating the whistle, you can skip this step. Increasing the throttle should activate the whistle and give audio feedback as to the sensitivity. The sensitivity setting has a range of 1 to 12, indicated by the number of times the F2 LED blinks. Lower numbers correspond to higher sensitivity. Pressing the Volume (+) button step through the available settings. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 20.

Setup Step 20 - Filter Rate

The Filter Rate controls Sierra's sensitivity to minor track voltage fluctuations due to pulse power, dirty track, etc. A high filter rate will smooth out even the most dramatic voltage changes, but also slows down Sierra's responsiveness to normal


F2 LED: LED blinks Filter setting



throttle changes. A low filter rate on the other hand, increases responsiveness, but may also result in the whistle sound being activated inadvertently if the voltage control mode is being used (Step

14). Normally, you should not have to make this adjustment. If you find that the whistle blows excessively, try increasing the filter rate. If the whistle doesn't blow at all or you are using a throttle with momentum, try the lowering the filter rate. The filter rate setting is indicated by the number of times the F2 LED blinks and has a range of 1 to 12 with larger numbers corresponding to a lower filter rate. Pressing the Volume (+) button will step through the available settings. Once you have made the adjustment, press and release the Volume (-) key to exit or press and hold the Volume


Setup Step 21 - Software Version Number

This is a view-only mode. In the case of some difficulty, it is often useful to determine the software version number, as sometimes changes are made between production runs to enhance performance. Press and release the Volume (-) key to exit or press and hold the Volume (-) key for 2 seconds until you hear a short toot and proceed to Step 22.

Setup Step 22 - Reset Warning

This mode warns you that you are about to set all the setup parameters to their factory default values, giving you an opportunity to change your mind before this happens! Pressing the Volume

(+) key accepts the Reset Warning and automatically takes you to Step 23 - System Reset. If you do not wish to reset values to their factory defaults, press the Volume (-) key! You will return to Operations Mode with no further changes. If you really want to reset everything to factory defaults - press the Volume (+) button. You are now in Setup Step 23 and should proceed as outlined below.

Setup Step 23 - System Reset

OK, you are here, so you really wanted to do it! The F1 LED will blink 23 times and the F2 LED will blink rapidly. You will hear the whistle blowing short blasts continuously. Last chance! To exit without making changes and resetting the parameters, press Volume (-). If you really want to reset, press Volume (+) NOW. Pressing either key will bring you back to Operations Mode.

OPERATING THE SOUNDTRAXX SIERRA SOUND MODULE

Whew! Now that we’ve installed the Sierra module and have programmed it to suit our locomotive, it’s time to run trains! This section is intended to give you a general feel for how Sierra is used in operation. We had to make a few assumptions on how Sierra is set up and for the most part, will assume you’re using a powerpack for control of the sound system.

At the Roundhouse

It's time to fire up the engine. Turn your throttle voltage up to about one volt or so and you'll hear the boiler gently simmering away and the airpumps pounding out a steady cadence as the airline builds up pressure. Once pressure has been built, the pumps will slow down and eventually come to a stop. Turn up the throttle a little more to activate the dynamo and lighting effects.

Now it’s time to couple up the train. Start the engine moving slowly in reverse. The whistle will give three short blasts to signal the trainmen that you are backing up. What? You don’t remember your whistle signals? Get out of the cab and don’t come back until you’ve memorized Table

B by heart. If you have set the bell voltage threshold properly, the bell will begin to ring. As the locomotive’s coupler hooks into the train, a loud KLANK! can be heard...just like the real thing!

Bring the engine to a stop. The whistle sounds one short toot to let all know you are stopping and with a quick release of steam, you are ready to head out. The airpumps are pounding away again as the brake line fills with air.

On the Mainline

Now let's take the engine out of the yard. The whistle will give two short toots as you begin to move forward. The bell will ring as you slowly move down the tracks. As the train builds up speed the bell will turn off. As you near the first crossing, increase the throttle to activate the grade crossing whistle.

Into the Station

We’ve had some fun on the mainline but now we’re nearing the station. Tap the throttle up to let off a few long and loud whistle blasts to let everyone know we’re here. When you bring the engine to a stop, the whistle will give a short toot and the cylinders will blow off the excess steam.

After a moment, Fireman Fred will open the firebox doors and shovel a few scoops of coal onto the flames to keep the boiler ready for the next trip out. Clink! The doors close and it’s time for Fred to take a nap. But he knows better than to snooze for too long and if you hang around long enough, you’ll hear him get up and grease the valve gear and draft the firebox. If he lets the boiler get too hot, you’ll even the pop-valves go off. What a noise! After you have let the engine for sit longer than 2 minutes, Sierra will automatically shut off the sound effects to conserve battery life.

SoundTraxx Operating Notes

With a little practice, you’ll find controlling Sierra’s sound effects to be easy and fun! However, for maximum control, there are some subtleties to be aware of.

Background Sounds

The background sounds will turn on whenever Sierra senses the track power is above one volt.

Thus, by keeping the throttle turned on slightly, you can keep the background sounds effects running indefinitely (or at least until the battery runs down). When the throttle is set below one volt, Sierra will turn automatically turn off all sounds after about 2 minutes to conserve power.

Dynamo

The Dynamo and lighting effects will turn on when the throttle is set to about halfway between off and the starting voltage you have set in step 3 of the setup procedure. When the throttle is below this set point, the dynamo and lights will turn off after about 15 seconds.

26


Bell

The bell will turn on once the throttle has been turned up past the bell on voltage set point (Step

17 of the setup procedure) and will stay on until the throttle is either turned back below this set point or turned up beyond the bell off voltage set point. The set point voltages should be chosen carefully so that the bell can be readily turned off for switching operations without having to increase the locomotive speed beyond what might be considered mainline speeds.

Whistle Signals

When the whistle control mode has been setup for voltage or trigger switch operation, Sierra will produce forward, backup and stop whistle signals as appropriate. The forward and backup signals are activated whenever the throttle speed is turned up past the starting voltage set point (step

3 of the setup procedure) and the stop signal is activated when the throttle is below the starting voltage set point. To avoid excessive whistle blowing during switching operations, it is necessary for the train to be stopped or running for at least three seconds before the next whistle signal is given. Otherwise no signal will be given. When the whistle is setup for switched operation, whistle signals are inactive.

Grade Crossing Whistle

When the whistle is setup for voltage operation, the grade crossing signal is activated whenever the throttle is turned past the bell off voltage set point by simply turning up the throttle a few notches or so for brief moment. This is probably the trickiest effect to master and also requires that the whistle sensitivity and filter rate be adjusted appropriately for your type of power pack.

We suggest by beginning with a medium filter rate (between 6 and 10) and high sensitivity level

(between 1 and 3) and working from there. If the whistle blows excessively, decrease the sensitivity level. Likewise, if you can’t blow the whistle at all, increase the sensitivity setting. If you continue to have difficulty, try changing the filter rate. A higher filter rate (lower number) will result in less sensitivity and vice-versa.

Exhaust Chuff

The digital exhaust chuff has been optimized for low to medium speed operation. At higher speeds, the chuffs will begin to mush together and create an unintelligible roar. For this reason, we recommend setting up your engine to produce two chuffs per wheel revolution rather than four as most operators tend to run their trains at faster than scale speeds.

Airpumps

The airpump sound effect is designed to work like the real thing! As the airpumps cycle, Sierra simulates the build up of air pressure and will slow the airpump’s pump rate as pressure is built up.

Pressure can be released by rapid decreases in the throttle to simulate hard braking or activating the coupler sensor switch to simulate connection to a train brake line.

Charging the Battery

About the Battery

Your Sierra Sound System uses a 6 volt rechargeable gel-cell type battery to supply power when the locomotive is stopped or operating at low speed. The gel-cell technology was chosen for its high power density, ease of recharging and it has no memory effect unlike other battery technologies.

A fully charged battery will typically provide about 2-3 hours of continuous operation dependent mostly on how loud the volume is set to and how often the whistle is blown. The optional heavy duty battery will provide 4-6 hours of operation. To conserve battery life, Sierra will shutdown the audio and lighting functions after the throttle has been turned off for a few minutes.

However, it will continue to put a slight drain on the battery and eventually discharge it. Use the power switch to extend battery life between charge cycles (see page 16).

Caution: Use only the battery supplied with your sound system or factory recommended replacement. Do not substitute with another battery type such as NiCd or NiMh as damage to the circuit board may result.

Caution: Observe operating cautions posted on battery label.

Caution: Although the battery is sealed and spillproof, there is a possibility of a loss of a small amount of sulfuric acid electrolyte in the event the battery case becomes damaged from mishandling. Any sulfuric acid can cause severe burns to the skin and eyes.

If contact is made with a damaged battery, immediately wash the contact area with water for five minutes.

Battery Care and Maintenance

As with all rechargeable batteries, there are certain precautions that you must be take in order to get the maximum service life possible. Please note that because we cannot control how the battery is maintained, it is not covered under our regular warranty. However, observing the following recommendations will ensure your Sierra’s battery provides maximum performance:

Never allow the battery to become fully discharged as it may become permanently damaged.

Always turn the power switch off at the conclusion of your operating session.

Always recharge the battery and turn power off to the sound system before storing it away for extended periods.

When not in regular use, the battery should be recharged every four to six months even when left disconnected from the sound system.

High temperatures can shorten a battery’s life. Always store the battery in a cool dry place when not in use. The ideal storage temperature is between 40 and 60 degrees F.

To Charge the battery with the Overnight Charger

Plug the overnight charger into a 110-120VAC outlet and fully insert the plug into Sierra’s charging jack. The overnight charger will fully charge the battery in about 6 to 8 hours and can be left plugged in for longer periods without harm to the battery. Note that the sound system is automatically disconnected from the battery whenever the charger is plugged in and is not operational while being charged.

28


Caution: The battery must be adequately ventilated to prevent accumulation of explosive hydrogen and oxygen gases that may be generated during the charging process.

Caution: The battery may become permanently damaged if left outdoors in a discharged state during periods of below freezing temperatures. Always store the battery in a charged state and recharge every 4-6 months.

To Charge the Battery From Track Power

The battery will begin to recharge from track power as the track voltage is increased beyond about 7 volts or so. The charge time will vary with the throttle setting but typically requires several hours of running time to build a sufficient charge for extended low speed operation. For this reason, we recommend using the overnight battery charger if you plan to run your trains at low speeds for long periods of time. Charging time can also be decreased by lowering the volume to zero.

TROUBLESHOOTING

If you should have any difficulties with the operation of your SoundTraxx Sierra Sound System, first check this section for hints on troubleshooting. If you cannot isolate and find a solution for the problem, we suggest that you write the factory a note describing the problem in as much detail as possible before returning the unit to the factory (see Service and Warranty Policy).

No Sound

First check that the battery is plugged in and the power switch is on. If you installed the optional battery charger, be sure charging jack is unplugged. Double check the wiring connections to the speaker. Press the (+) or (-) button. If lights turn on, press the (+) button several times to increase the volume.

If the problem persists, try a different speaker. If the lights do not turn on, the problem is most likely a dead battery. See below.

No Sound or lights

Sound works for awhile and then stops

Sound volume drops and becomes distorted after awhile

Strange noises or erratic sound effects

Sound System powers up and then shuts off as soon as it blows a whistle

The above symptoms are characteristic of a weak or dead battery. Recharge the battery and the problem should go away.

The F1 and F2 lights flash but nothing else happens.

If Sierra’s memory becomes ‘scrambled’ Sierra will reset all settings to the factory default levels described in Table A and flash the lights to let you know that everything has been reset.

After about 30 seconds or so, the system will return to normal operation. Memory loss may occur if you attempt to operate the system with a weak battery. No permanent harm is done.

Whistle Signals are backwards

The track connections are backwards. Reverse the connections to terminals 7 and 8 and the problem should go away.

Grade Crossing Whistle does not work

Check that the proper control mode has been selected (Setup Procedure, Step 14). Depending on the type of power pack you have, you may need to adjust the whistle sensitivity or filter rate as described under Operating Notes (page 27). If your throttle has built in momentum,


29

you should turn the momentum setting to minimum as this will also interfere with the whistle operation.

Whistle, Bell or Hiss trigger switches do not work

Check that the proper control mode has been selected (setup procedure steps 14-16). You can verify the proper mode has been selected by simply connecting a wire to terminal 12 and tapping the other end to terminal 13, 14 or 15 as needed. Each time you tap the wire to the terminal, the corresponding sound effect should be activated. If the problem persists, check the alignment and distance of the trigger switches to the track activation magnets.

Exhaust Chuff does not work

If you are using the exhaust sensor switch, be sure that you have completed setup procedure step 1 first. You can verify correct setup by simply connecting two wires to terminals 11 and

12. With system turned on, tap the ends of the two wires together and you should hear a chuff each time you do so. If not, then return to step 1 in the setup procedure and make the appropriate adjustment.

Next check the electrical connections between the sensor switch and Sierra circuit board.

Finally it may be necessary to make an adjustment in the sensor’s or magnet’s position. The sensor should be less than 3/8" away from the magnet. The magnets should also be separated as far apart as possible. If they are too close together, the magnetic field that opens and closes the switch will remain strong enough around the wheel and the switch will remain closed.

If you are using the auto exhaust feature, be sure that the you have completed setup steps 1 and 3.

Battery does not recharge

If you are charging the battery from track power, it will take a while for the battery to recharge.

Charging time can be decreased by lowering the volume to zero.

If you are using the overnight charger, be sure the charging plug is plugged all the way into the jack.
