ZS23A Class 23 Baby Deltic ActiveDrive V18.07
Please spend a few moments to read these notes which have been produced so that you may obtain the maximum satisfaction from your new sound scheme.
The sounds should work perfectly when the decoder is fitted correctly. Individual locos may require some fine tuning that you can achieve with your DCC controller.
What is ActiveDrive?
This is a system developed to allow more prototypical sounds to be deployed across a wide range of operating conditions.
The sounds have been programmed in such a way that you, the user, may change the way that the sounds respond to your driving style or needs. This avoids the need for reprogramming and all the additional costs that would imply.
Engine Start Up.
F 1 will crank and start the engine which will then settle down into Idle
Throttle Response Scheme.
As supplied, the decoder will produce the sounds of your loco with a train on the hook.
After the start-up routine the loco will stand with the diesel engine, the Prime Mover (PM), ticking over at idle.
The sounds will respond to the throttle control in the following way:
Select speed step 1. The brakes will release, the PM will increase power to get the loco moving, and will continue until at higher speed, a further ramp up will be initiated until the final high speed running sounds begin. The precise speed steps will depend upon your model, so I suggest you make a note of the actual figures for your later use.
The sounds will spool down at similar points on deceleration.
The model can be driven in this way without ever needing to use any control other than the throttle .
For those of you who prefer something more immersive, in this version there are extra control features to further enhance your driving pleasure.
Coasting
No matter what actual speed your model is travelling at, or which engine note range is playing, reducing the throttle by 10 speed steps (of 128) will spool down the engine sounds to ‘Coasting’
The coasting sound will continue until you accelerate; at which point the sounds will change to those relevant to the current speed.
Alternatively, to force the engine to play idling sounds, or to avoid engine ramp up when pottering about the yard, use F6 at any time
Speed Lock
This feature allows the road speed to be locked whilst the throttle control is used to control the engine power sounds playing.
Accurately simulating the sound of a heavy train slowly climbing a gradient with engine at full power is as easy as depicting it coasting down a gradient with the engine at Idle with this single new feature.
Here’s how it works.
Engage the SpeedLock Key, (F7) to fix the model’s road speed temporarily. The throttle now directly controls the engine sounds only. Increase speed steps to apply more power, decrease speed steps to spool the engine down to lower power bands or to Idle.
Disengage the SpeedLock Key when you wish to return control of the model’s speed to the throttle.
Notch Down
During any driving sound ‘loop’, at any steady engine speed, it is possible to cause the engine power to spool down to the level immediately below. This is easily achieved by reducing the speed by one step only E.G., if the loco is playing power band 3 sounds, reducing speed with your throttle by one step will cause the sound to immediately spool down to the sound of power band 2, if in power band 1, it will spool down to idle.
Acceleration of one speed step or more will immediately ramp the sound back up to the higher power. So you can now, at any road speed, vary the engine note by reducing or adding a single speed step.
Heavy Train/Light Engine Mode Selection
The default setting is for ‘heavy train’. Inertia is high so acceleration (and deceleration) is restricted.
Activated by F5, Light Engine enables multi-function changes with one key. The switched features include reduced inertia setting to allow more rapid acceleration and engine sounds which accelerate differently.
F5 can be operated at any speed to give another way in which the engine sounds at a given road speed may be modified instantly.
Note. This works best if you switch F5 on or off whilst the engine sounds are playing in idle. Once switched, you can leave it that way, but any further change should also be made with the engine sound again playing the idle loop. Just to be clear, the actual speed is unimportant, but the engine sound must be idling. You can achieve this in several ways as discussed above.
Brakes
F2 will give the sound of air brake applications. They can be ‘dabbed’ or held for varying length. The sound will respond accordingly.
However, if the throttle is reduced beforehand, as a real driver would do before braking, a braking force will be applied which will continue to increase the longer F2 is held. Short dabs will provide speed trimming, held down continuously will result in a controlled ‘Emergency Stop’.
PowerCab users please note that the Horn/Whistle button operates the same sound/function as the F2 Key, but set as ‘momentary’. This facilities the precise operation of the brakes and should be used instead of F2.
Other systems may have F2 set to operate as ‘momentary’ by default, or can be set to do so.
Engine Speed-up
F7 is a complementary key to F6. Whilst the latter forces the engine sounds to Idle, F7 will speed up the engine to notch 3. This will produce the sound of the compressor speed up routine, but can also be used to provide a medium power sound prior to pulling away.
Remember to switch this key off before stopping!
Live Volume Control
Provided the sound is switched on and the ‘fade’ button is not active, it is possible to change the overall volume to suit changing needs.
Function Keys List
F0 –Lamps
F1 -- Sound on/sound off
F2 --Brakes
F3 – Horn Hi
F4– Horn Lo
F5 – Light load key
F6 – Engine to idle
F7 – Speed Lock
F8 – FO1
F9 – Wheel Flange
F10 –Brake release
F11 –Brake squeal
F12 –Spirax valves ticking
F13--Compressor
F14--Door slam
F15--Air release
F16--Lo horn
F17--Hi Lo horn
F19--Mute
F27--Volume down
F28--Volume up
In each case, disengage the F key when the desired level is attained. Set F27 and F28 as ‘momentary’ if your DCC controller allows you to do so.
Note: If the volume controls appear to not function, check that F19, F27 and F28 are disengaged before making a further attempt.
It’s now down to your skill and knowledge to simulate any eventuality!
