Hornby Class 47 - Sound Decoder Manual

Introduction

The Hornby 'Class 47' diesel/electric locomotive is fitted with a 'Hornby Twin Track Sound decoder' which offers adjustable motor control and a range of realistic engine sounds including full acceleration/deceleration sounds, horns, and other appropriate locomotive noises associated with the 'Class 47' locomotive.

Main Features

• Supports Short and Long decoder addresses.
• Adjustable Acceleration and Deceleration.
• Back EMF Load Compensation.
• Automatic or manual adjustable engine control methods. Both methods can be used together for realistic engine control.
• Two sound channels allowing for simultaneous play of full locomotive diesel engine sounds, and individual spot sounds e.g. Horns. Whistles, Brakes, Engine start, wagons clanging and coupling etc.
• A total of 18 different 'spot sounds' in addition to the locomotive's diesel motor start/stop and running sounds are available.
  Note: Only one of these individual spot sounds may be played at the same time.
• Authentic start-up sounds for the 'Class 47'. You can choose between warm or cold start up. Loco start is activated by F1 on the controller. If F9 is previously selected the loco will perform a 'Cold Start'. The engine will continue to attempt to start until F9 is pressed again, after a "cough and a splutter" the engine will start... Loco engine sounds are turned off by selecting F1 again. Individual spot sounds (horns etc,) can be played at any time without the locomotive's engine sound being interrupted.
• It is possible to alter the volume of each sound through an individual dedicated CV. i.e. there is effectively a simple volume mixer on board the decoder. Volume may be adjusted in 8 steps, 0-8.
• The decoder is equipped to support directional Front and Rear Light operation via F0 on the controller providing the locomotive is equipped with lighting connected to hardware function channels 1 and 2 of the decoder. Note: The Class 47 TTS does not have lights installed.
• The decoder is equipped with 1 aux function output controlled by F25 on the controller. (This is hardware function channel 3 on the decoder.) Note: The Class 47 has nothing connected to the aux output.
• 
  The decoder does not support sound under DC operation. Sounds can only be played under DCC operation. This statement applies to all sounds both running and individual spot sounds. The locomotive's motor may be controlled under DC operation. See the Function List in Section 2 for a complete list of decoder features.

Function List

Note Regarding Toggle and Momentary Action Function Control. (Check your controller manual!)
Some controllers only offer 'toggle' control for function activation. i.e. Once the function key is pressed it remains 'On.' If a specific sound or function is designed to play/activate once, the function key will need to be pressed again to return the controller to 'function off' status before it is possible to activate the same function again. e.g. the Hornby 'Select' operates in this manner while the Hornby 'Elite' has both 'toggle' and 'momentary' control of functions, which is ideal for controlling both 'Play Once/Activate Once' and 'Looped' spot sounds.

Note re Lighting Control. (Only if loco is equipped with lights etc.)
The TTS decoder fitted to your locomotive supports lighting control as standard. However, the following functions are only available if lighting is fitted to the loco.

• Front and Rear Lights are activated by F0 on the controller. (Decoder hardware function outputs 1 and 2 using the decoder's yellow and white wires.)
• The Auxiliary Function output is activated by F25 on the controller.
  (Decoder hardware function output 3 using the decoder's green wire.)

Understanding Diesel/Electric locomotives

How does a diesel/electric locomotive work

Although the real locomotive has a diesel engine, this engine does not directly drive the locomotive's wheels. The engine is used to turn a generator which provides electricity for electric motors (traction motors) that drive the locomotive's driving wheels. As such the driver does not control the locomotive's speed with a direct throttle like a car, rather the driver will Notch the diesel engine up and down; thus varying the amount of power available to the traction motors in response the amount of effort needed at any time to move or maintain the speed of the locomotive. Typically, when he moves off with a load or encounters an incline etc he will notch the revs of the engine upwards. When the locomotive is rolling after initial acceleration he may well 'Notch down' (Notch back) the diesel engine. Due to the nature of the diesel electric control system there is a noticeable degree of lag between the locomotive's physical speed and the engine revs commanded by the driver.

When shunting heavy loads the driver may carry out 'Thrashing' of the locomotive's engine i.e. applying bursts of high revs rather than just simply Notching the diesel engine upwards. Thrashing can be thought of as the driver 'stamping on the throttle.' F8 allows you to thrash the locomotive's engine. The action of F8 is that the engine will increase its current running notch by a two notches, where possible. See explanation under Manual Control later in this manual.

Driving & controlling the engine of your TTS Diesel Locomotive

Automatic Engine Control

The TTS locomotive will rev up and down (notching) automatically depending on the throttle applied to the locomotive. For basic use it is not necessary to fully understand how the sound system selects the appropriate sound to be played. If you wish to understand fully how the 'automatic' system work please see 'CV table 2: Engine Sound Transition Configuration'. Using the CV table it is possible to tune the automatic system to suit the way you wish to drive the locomotive. But for now, until you get used to how your locomotive works, we suggest leaving these adjustments in their default values. The automatic system can be overridden at any time by using the manual control engine control functions.

Manual Engine Control

Generally, the locomotive engine will carry out automatically the transition between different levels (Notches) of the diesels rev range dependent on the speed step applied from the DCC controller. The automatic process can be overridden or modified by the use of the NOTCH up/down functions (F5 & F6) or by the specialist control features 'Thrash' (F8) and 'Return to IDLE' (F7.) Please note in the following table describes how each engine control function is designed to work.

regarding loss of automatic or manual engine control. Please READ THIS!

If you are using any type of controller that does not indicate the status of a function i.e. there is no display telling you whether a function is enabled (on) or disabled (off,) or a controller that only offers 'toggle' function control; then it is possible that you could become confused re the set state of control of the engine sound e.g the automatic notching up and down process will cease to work because you have inadvertently left F8 (Thrash) in a permanent 'on' state.

Leaving other engine controls i.e. F5 (Notch Up,) F6 (Notch Down) and F7 (Return to Idle) will not cause permanent loss of the automatic control but, they will not activate when commanded as they must be returned to the 'off' state before they can be re-activated.

The above can be very confusing and lead the user to wrongly think there is a fault with the TTS decoder.

Solution: A quick and simple solution to diagnose whether you have left a function "enabled" is to simply re programme the decoder to a new address number that has never been used; and see if the decoder engine sound starts to behave correctly again (DO NOT ACTIVATE any engine control functions.)

Note: resetting the decoder or, resetting the controller will not correct this issue. Some controllers may set all function controls to 'disabled' when reset. Please check you controller's documentation.

Driving Tips and suggestions

By careful manipulation of the various Function controls on the DCC controller it is possible to simulate a 'realistic' driving experience. It is recommended that you study the full list of sound functions, and familiarise yourself as to which are 'toggle' control or 'momentary' control. Take note of the 'Loop' play sounds, and those that 'Play Once' for a specific duration. It is recommended that you do this; as it may have some bearing on how you use your controller. See previous note re controllers that do not support 'momentary' action function control.

Start up... There are two possible start up modes. "Warm" or "normal" start and "Cold Start." On pressing F1 (toggle on) the loco engine will warm start and settle to idle revs. However, if F9 has been pressed (toggled on) before pressing F1 the TTS decoder will use the "Cold Start" mode for start up. In "Cold Start" mode the TTS decoder will play sounds of the engine being continually turned over for as long as you wish. Starting diesels on a cold day with snow on the ground can take many tens of minutes. If you wish you can simulate this situation i.e... the "Cold start" sounds will loop for as as long as you wish. On releasing F9 (Toggle Off) the engine will "cough and splutter" and a successful start will be made with the engine settling to Idle running in the usual manner.

When moving off the loco will automatically play the sound of the pneumatic brake releasing.

When the locomotive is running it is possible to notch up/down using the decoders automatic features by making very small adjustments to the controller's throttle. Because the loco decoder simulates inertia via the acceleration and deceleration setting (see CVs explanations) no apparent change will be made to the locos speed. On each minor deceleration the locomotive's engine will notch down and on an increase of the throttle; the loco will notch up to the most appropriate notch for the locos current speed.

Manual Notch up and Notch Down. It is possible to take control of the locomotive's engine via the controller's function controls. F5 will allow you to Notch up one step. F6 allows you to Notch down one step. Both F5 and F6 are 'momentary' functions.

Thrashing It is possible to take control of the locomotive's engine via the controller's function controls. F8 will allow you to "thrash" the locomotive's engine i.e. the engine will Notch quickly upwards, remain at the new Notch until F8 is released. F8 is a toggle function and overrides any automatic Notching due to throttle changes while active. If F8 is disabled then the locomotive will play the appropriate Notch sound for the locomotive's current speed.

Return to Idle Override F7 is a momentary function which will cause the locomotive engine to return to idle. Until the locomotive engine has returned to idle the system will not respond to any other manual or automatic Notch changes. This function might be used when the locomotive has attained the desired speed and it is immediately required to go to 'coast'.
If F7 is enabled while the loco is in 'Thrash' mode (F8,) F8 must be manually turned off/disabled before locomotive engine control can resume.

Note: Sometimes diesel locomotives were used as 'standing generators' e.g. possibly to power plant during engineering works etc. Because the diesel TTS sound system allows independent control of the engine speed from the actual speed of the locomotive, using F8 Thrashing, F5 Notch up, F6 Notch down and F7 Return to Idle; it is possible to run the engine at high revs while the locomotive is stationary.

Tips for Hornby ELITE users... If you hold any button on the Keypad for more than 3 seconds it automatically operates as a momentary function control. i.e. the function is 'released' after you stop pressing the button.

A single press of the button toggles the function on until it disabled via another button press.

We have found that the best way of using the functions F5 and F6 (Notch Up/Down) and F7 (Return to idle) is to press and hold the appropriate button until you hear the locomotive's engine note change.

F8 Thrashing is a toggle function so it is only necessary to quickly press button 8 to enable the Thrash action. Pressing button 8 again returns the locomotive engine to normal 'automatic' response.

Tip for Hornby SELECT users... Please note the SELECT does not support 'momentary' action function control. Please read the note re using non-momentary control functions.

CV Table 1

For clarity we have divided the decoder CV table in to 3 sections.

Table 1 shows the standard decoder configuration CVs.
Table 2 shows the engine sound control parameters.
Table 3 shows the locomotive spot sounds (horns sounds etc) volume settings.

Standard Decoder Configuration

CVs... 'Class 47' Running Parameters & Decoder setup

CV3 and CV4 Acceleration and Deceleration

Any value less than the default of '15' is likely to cause sound playback to operate incorrectly. You may like to increase the values here for added realism.

Read Only CVs that contain version information

Please note the following CVs are subject to change.

CV8 Manufacturers ID and Reset

If read, this CV will report the manufacturer's ID for Hornby Hobbies 48.

Writing the value '8' to CV8 will perform a 'general reset' of all CV variables to factory default values.

The decoder also has a unique feature, i.e. writing the value '5' to CV8 will reset all sound volume levels to default levels, i.e. CV160 to CV180 will be returned to default values. All other CV values (non-sound related) will be left as programmed by the user.

CV10 Back EMF Cut-Off Point

The decoder supports 'load' compensation. This is a feature that tries to maintain a constant speed of the locomotive as the load on the motor changes, i.e. when ⁷ negotiating inclines and curves, etc.

This is achieved by monitoring the actual speed of the motor via the motors BEMF (Back Electromotive Force) and comparing the voltage level detected to the Speed Step command sent to the decoder. Speed Steps are in the value range 1-128. Using this CV allows a cut-off point to be set for the Speed Step value where the BEMF load compensation action ceases to be applied.

Generally, this value is left as default (128); but in some rare cases adjustment of this CV can assist smoothness of lower speed running.

Example: If the CV is set to a value of 100, the load compensation will not be applied above Speed Step 100.

CV29 Decoder Basic Configuration

The supported functions are:

Add the desired values for each function to get the needed value of CV29.
Example: The default value for CV29 is 6, i.e. 28/128 Speed Steps + Enable analogue operation = 2+4 = 6.

Further notes re CV29

Bit0 (Add 1 to activate) is used to control the default direction of the locomotive. This is useful if the decoder has been retro fitted to a non-DCC fitted locomotive and a wiring error has been made re connection to the motor. Other uses are where the model railway layout requires reversed direction operation.

Bit1 (Add 2 to activate) is used to set the decoder to detect the correct location of the direction command for lighting control, i.e. whether the decoder is expecting 14 or 28/128 Speed Steps. It is not usual to edit this feature as the decoder will handle this function automatically in most cases.

Bit2 (Add 4 to activate) is used to control whether the decoder will operate on both DC and DCC layout control. By default both forms of power are enabled. It is recommended if only running on a DCC controlled layout to turn off DC operation, i.e. CV29 = 2 if only changing this feature of CV29.

Bit5 (Add 32 to activate) The decoder stores Short Addresses in CV1 and Long Addresses in CV17 and CV18. Bit5 is used to tell the decoder where to find its allocated address, i.e. for Long Addresses Bit5 is enabled.

This feature is usually handled automatically, it is not usually necessary to edit the value of this Bit.

Please Note

If a decoder is returned to default settings, i.e. address 03, etc., if Bit5 is turned 'on' to make the decoder operate in 'Long Address' mode, the decoder will respond to address 100. Turning Bit5 to the 'off' state will return the decoder to 'Short Address' mode, i.e. address 03.

If the decoder has been previously used with both Short and Long Addresses toggling this Bit on/off allows the decoder to use either the short or long address previously programmed.

CV150-154: Motor Control Method

Motor speed control is achieved using a controlled loop system (algorithm) where the decoder checks the speed of the motor and compares the retrieved current speed information of the motor with the 'desired' speed setting.

For example, if the locomotive is climbing a hill, the tendency is for the locomotive to slow down compared to the desired speed set from the controller. The control system will detect this and try to compensate the speed drop by increasing the drive to the motor. Similarly, when a locomotive moves off from standstill, the control system will try to compensate for the tendency for the locomotive to remain static (inertia at rest.)

The control algorithms employed are referred to as PIDs. This refers to Proportional - Integral - Differential. Further explanation is outside the scope of these notes but from the point of view of this note it is the P and I factors that interest us, as follows.

How the decoder reacts and controls the compensation system for speed drops etc. can be adjusted. Adjustment of the motor drive characteristics is carried out with the following CVs.

CV150 allows the selection of one of two base motor control algorithms. The CV value range is 0-1.

This corresponds with:
CV150=0 Algorithm 1 is in control.
CV150=1 Algorithm 2 is in control.

Each of the two algorithms can be further adjusted by use of their associated CVs.

Motor control Algorithms: Description

Algorithm 1 (CV150=0)

This algorithm is a non-linear curve which offers lower controlled speed in the low speed end of the curve. This is similar to the Hornby decoder type R8249.

CVs 151 & 152 offer control of the P and I factors of the Algorithm 1.

Generally speaking, the higher the setting for these two values the motor control becomes 'Stronger' but at the cost of losing fine control. By default this algorithm is set with the P and I values set to 8.

Algorithm 2 (CV150=1)

This algorithm is a linear curve which offers higher controlled speed in the low speed end of the curve. This is similar to some Lenz type decoders.

CVs 153 & 154 offer control of the P and I factors of Algorithm 2.

By default this algorithm is set with P and I values of 215 and 115 respectively.

Note that CV10 (BEMF cut off) also affects motor control performance.

CV Table 2: Engine Sound Transition Configuration

The locomotive's engine sounds will rev up and down and hold at different rev levels (or Notches) depending on the speed step applied from the controller. The system is designed to operate with 128 speed steps (0-127.)

Please ensure that your controller is set to support 128 speed stepping (0-127.) Not all controllers have the ability to display actual speed step values, in practice this doesn't really affect your driving experience. For the purpose of explanation we will refer to speed steps to explain how the 'engine sounds' react to different throttle levels etc.

The TTS Diesel Sound System/How it works

The decoder in your locomotive is designed to operate at 4 different rev levels. These are the 4 rev levels. Each rev level above 'IDLE' are referred to as 'NOTCH'.

The rev levels:

IDLE (Standing or smallest amount of engine revs.)
NOTCH 1 (Slow Engine Speed)
NOTCH 2 (Medium Engine Speed)
NOTCH 3 (Fast Engine Speed)

The way that the locomotive engine sound responds is controlled by the throttle on your controller i.e. as you increase the actual speed of your locomotive on the track, so the sound responds accordingly. The way the locomotive sounds change can also be controlled by use of certain controller functions (F#). However, for the moment, we will examine how the engine sound automatically responds under just throttle control.
Take a look at the CV table.

The table indicates configuration of the speed step value that triggers the play of the next NOTCH in the sequence i.e. NOTCH 1 through to NOTCH 3. These are referred to as Trigger Thresholds - TT.

To add further 'realism' to the driving experience we have also added a CV associated with each TT. This is the Trigger Threshold Window - TTW.

In each case, the TTW CV sets a value that is added to the TT value. This creates a window of speed steps values that are used to control the engine sound in a specific way i.e.

• When the speed step transmitted from the controller falls in to the range between TT and TT + TTW the engine sound will NOTCH up and then immediately NOTCH down. Please note that once the speed step transmitted is in this range no further automatic NOTCH Up/Down action will occur until, after the speed step has increased/decreased and then re-entered the TTW.
  This process limits the engine transition lag between minute throttle changes.
• If the speed step transmitted exceeds TT+TTW than the engine will NOTCH up and remain at that NOTCH.

Engine Sound Transitions Configuration

Acceleration

Here are some examples using zero as a starting point of how the system responds using the default settings set out in the table above...

1. You turn the throttle up until you hear the brake release sound and the locomotive just moves. The speed step applied is less than 5.
   Decoder plays the following sequence of engine sounds...
   IDLE Only - explanation... if the brakes are released the loco will crawl with the engine idling.
2. You turn the throttle up from zero to speed step 8.
   Decoder plays the following sequence of engine sounds...
   IDLE - Transition to NOTCH 1 - then back to IDLE.
3. You turn the throttle up from zero to speed step 12.
   Decoder plays the following sequence of engine sounds...
   IDLE - Transition to NOTCH 1 - Remains in NOTCH 1.
4. You turn the throttle up from zero to speed step 33.
   Decoder plays the following sequence of engine sounds...
   IDLE - Transition to NOTCH 1 - Transition to NOTCH 2 - then back to NOTCH 1.
5. You turn the throttle up from zero to speed step 66.
   Decoder plays the following sequence of engine sounds..
   IDLE - Transition to NOTCH 1 - Transition to NOTCH 2 - NOTCH 3 - Remains at NOTCH 3
   Note: When the locomotive moves off, brake release sounds are played automatically.

Deceleration

So far we have talked about Acceleration, Deceleration follows different rules. Basically, at any given speed step the appropriate NOTCH or IDLE sound will be playing. On first decrement of the Speed Step the NOTCH playing will transition to the NOTCH below it.

The second decrement of the speed step will cause the system to transition to the next NOTCH downwards. This process will repeat until the sound playing is 'IDLE' and it is not possible to go any lower.

If the throttle is increased after a deceleration event, the acceleration rules will apply as described previously.

Manual Control

In addition to the 'automatic' engine control described previously the decoder also supports "manual" engine control via Function numbers F5, F6, F7 and F8.

F5 NOTCH UP
F5 is a momentary action control that will force the engine sound to increase to the next NOTCH in the NOTCH sequence. This is possible when IDLE, NOTCH 1 and NOTCH 2 are playing.

Example: If the loco is playing the IDLE sound then pressing F5 once will increase from IDLE to NOTCH 1.

F6 NOTCH DOWN
F6 is a momentary action control that will force the engine sound played to decrease to the next NOTCH in the NOTCH sequence. This is possible when, NOTCH 3, NOTCH 2 and NOTCH 1 are playing.
e.g. If the loco is playing NOTCH 2 sound pressing F6 once will decrease from NOTCH 2 to NOTCH 1.

F7 RETURN TO IDLE
F7 is designated as momentary control action. Once triggered the engine sound will decrease from whatever Notch is currently playing to IDLE playing all engine sound transitions as the engine rev rate drops.
No other control engine function is available until the engine reaches IDLE.

F8 THRASH
F8 is a Toggle function. F8 simulates what happens when the driver 'stamps' on the locomotive's throttle. i.e. the driver applies a lot of power in a sudden burst to overcome a heavy loading situation e.g. when negotiating an incline or moving off with a very heavy load in tow.

The 'Thrash' function increases the current NOTCH by 2 steps. It locks the loco at the new NOTCH until 'toggled' off. When toggled back to 'off' the NOTCH sound played will be appropriate to the current speed of the the locomotive. This is to accommodate any acceleration of the locomotives speed during the 'locked' Thrash setting.

Note: F7 'Return to Idle' override F8 'Thrashing'. If F7 is pressed you must ensure F8 is then disabled in order to return to normal engine control...

Example:

• If the loco is playing IDLE, when F8 is toggled on the engine sound will transitionand play NOTCH 2
• If the loco is playing NOTCH 1, when F8 is toggled on the engine sound will transition and play NOTCH 3
• If the loco is playing NOTCH 2, when F8 is toggled on the engine sound will transition and play NOTCH 3 (one step!)
• If the loco is playing NOTCH 3, when F8 is toggled on there will be no action

CV table 3: Spot Sounds Volume Configuration

The volume level of the locomotive 'engine' sounds and each 'spot' sound (e.g. horns etc) is controlled by its own dedicated CV. See table below.

We have set all volume CVs to a default value of 4. This will allow you to hear all sounds clearly. However, how you may want to set the relative balance of the individual sounds differently. It may depend on whether you want to 'hear' the locomotive at a "distance, close up, or possibly when in the driving cab.

In the table below we have added some suggestions re volume levels you may wish to try. These are based on how the locomotive may realistically sound from a scale distance of approximately 15 metres. Remember, these are only suggestions that act as a starting point if you wish to experiment with the relative volume level of each sound...it's up to you!

Volume Settings (Mixer Section)

See 'The Mixer Section' re CV explanations etc.

Note: For each sound there are 9 possible settings i.e. 0-8. 0 is no sound, while 8 is full volume.
The sound set of the loco has been balanced in the factory so that sounds play at the correct volumes relative to each other. However, individual sounds may be fine-tuned in volume by the user to suit by adjusting their associated CV... Please see table above.

Setting up volumes using the 'Mixer' Section

It is recommended that the following CV adjustment procedure is executed in 'Operate Mode' with the loco on the 'Main' track. This is sometimes referred to as 'Programming on the Main'.

Using this programming method greatly speeds up the process of setting the sound balance of the decoder. However, please note you will need to return the loco to the 'Programming Track' and use 'DIRECT CV' Programming mode in order to read back any CV values.

Suggested Sound Volume Set-up Procedure

Start by setting up the general loco volume level by adjusting CV182 until the volume level of the loco 'start and engine running' sounds are at the desired level.

The sounds on board the loco decoder have been preset in volume to give a "balanced" sound at whatever volume CV182 is set at. However, each individual sound component can now be adjusted in volume to suit.

Using CV table 3, run through the list of 'spot' sounds making any adjustments to their volumes by editing the appropriate CV as necessary.

Note: If you become confused while adjusting the sound volumes the following will assist:

CV8. Apart from the usual 'general reset' function common to all Hornby decoders (CV8=8,) on the sound decoder CV8 has a secondary function i.e. writing the value '5' to CV8 will reset all sound volume levels to default levels.
i.e. CV161 to CV 180 will be returned to default values i.e. 4. All other CVs will be left as programmed by the user.

Once you are more familiar with the sound volume set up procedure you will find that it is very easy to set a sound volume levels while the locomotive is on 13 the Main track.

This technique allows you to instantly hear the sound volume change as the associated CV is edited. Please see your DCC controller manual re programming in 'Operational Mode' or 'Programming on the Main'.

Note, if you wish to read back any CV setting you must place the loco on the 'Programming Track'. It is not possible readback CV values in OPERATE mode while a locomotive is on the main track.

Glossary of Function Sounds

Most function sounds are self explanatory. The following additional explanations may be of interest.

Compressor: Charges the air tanks so they are full of compressed air to work the brakes.

Fan: Sometimes called a 'scavenger' fan, this sucks in air from outside the loco to help keep the engine room cool.

Primer:A pump used to remove air from the fuel lines and fill them with diesel, otherwise the engine would not start.

Spirax:A valve fitted to an air tank that makes a ticking noise when the engine is not running to let out any condensation to prevent the tank from freezing.
