自動(dòng)關(guān)閉油門
對(duì)于其他機(jī)車來說，揚(yáng)聲器外殼不需要花哨，可以用苯乙烯板、低音木甚至是硬紙板制成！一個(gè)35毫米的薄膜罐通常能產(chǎn)生很好的效果，紙巾卷的紙板管中心也是如此。數(shù)字聲音解碼器最適合在投標(biāo)中安裝，盡管它將適用于大型機(jī)車的鍋爐。鍋爐安裝的優(yōu)點(diǎn)是，需要在發(fā)動(dòng)機(jī)和投標(biāo)方之間布線的電線要少得多。這通常會(huì)以一些鍋爐重量和牽引力的可能降低為代價(jià)。DSD在長(zhǎng)時(shí)間運(yùn)行后變熱是正常的，其內(nèi)置的熱過載保護(hù)將在過熱時(shí)自動(dòng)關(guān)閉油門和音頻放大器。因此，將DSD安裝在能夠散熱最多的位置非常重要。避免將DSD放置在熱源（如電機(jī)或燈）附近。您還需要決定如何同步排氣。DSD提供兩種同步方式。第一種方法是使用機(jī)械凸輪，它通過打開和關(guān)閉與機(jī)車車輪或車軸的開關(guān)觸點(diǎn)來工作。
驅(qū)動(dòng)輪內(nèi)表面接觸
排氣凸輪開關(guān)最好安裝在與驅(qū)動(dòng)輪內(nèi)表面接觸的位置。這將提供最精確的同步，甚至在機(jī)車加速過快時(shí)產(chǎn)生車輪打滑效應(yīng)！在緊急情況下，排氣凸輪可以與軟車軸一起使用，盡管同步效果并不精確，除非軟車軸直徑是機(jī)車司機(jī)直徑的精確倍數(shù)。排氣同步的另一種方法是DSD的自動(dòng)排氣功能，它產(chǎn)生與節(jié)氣門設(shè)置成比例的爆震。對(duì)于機(jī)械凸輪難以安裝的機(jī)車，如N型和較小HO型機(jī)車，建議采用這種方法。當(dāng)與可編程速度曲線一起使用時(shí)，除了最慢的速度外，很難區(qū)分自動(dòng)排氣和排氣凸輪之間的差異。接下來，您需要考慮將使用哪些燈光效果。DSD提供四個(gè)輔助功能輸出，可用于控制微型燈或LED。兩個(gè)輸出通常用于車頭
Auto throttle off
For other locomotives, the speaker shell does not need to be fancy, and can be made of styrene board, bass wood or even cardboard! A 35mm film can usually produce good results, as does the center of the cardboard tube of the tissue roll. The digital voice decoder is most suitable for installation in the tender, although it will be suitable for large locomotive boilers. The advantage of boiler installation is that there are much fewer wires between the engine and the Bidder. This usually comes at the expense of some possible reduction in boiler weight and traction. It is normal for DSD to become hot after a long time of operation, and its built-in thermal overload protection will automatically close the accelerator and audio amplifier in case of overheating. Therefore, it is very important to install the DSDs where they can dissipate the most heat. Avoid placing DSDs near heat sources such as motors or lamps. You also need to decide how to synchronize the exhaust. DSD provides two synchronization modes. The first method is to use a mechanical cam, which works by opening and closing the switch contacts with the locomotive wheels or axles.
Drive wheel inner surface contact
The exhaust cam switch should preferably be installed in contact with the inner surface of the drive wheel. This will provide the most accurate synchronization, even when the locomotive accelerates too fast, resulting in wheel slip effect! In an emergency, the exhaust cam can be used with the flexible axle, although the synchronization effect is not accurate, unless the flexible axle diameter is an accurate multiple of the locomotive driver's diameter. Another way of synchronizing the exhaust is the automatic exhaust function of the DSD, which generates detonation in proportion to the throttle setting. For locomotives that are difficult to install mechanical cams, such as N type and smaller HO type locomotives, this method is recommended. When used with a programmable speed curve, it is difficult to distinguish between automatic exhaust and exhaust cams except for the slowest speed. Next, you need to consider which light effects will be used. The DSD provides four auxiliary function outputs that can be used to control micro lamps or LEDs. Two outputs are usually used for the vehicle head
