隔離電機(jī)注意此步驟
因為這是成功將任何機(jī)車轉(zhuǎn)換為DCC運行的最重要步驟。兩個電機(jī)電刷連接必須電氣隔離，以便它們僅由DSD電機(jī)輸出驅(qū)動。我們不是在開玩笑！數(shù)字聲音解碼器用戶手冊9停止未能正確隔離電機(jī)將損壞解碼器，并將其變成有效但壽命短的煙霧發(fā)生器！我們的保修明確排除因電機(jī)隔離不當(dāng)而造成的損壞；但是，如果您損壞了解碼器，只需將其返回到Throttle Up！連同服務(wù)費（請注明當(dāng)前金額），我們將及時維修并退還。從機(jī)車和招標(biāo)框架上拆除鍋爐和招標(biāo)外殼，開始電機(jī)隔離。在繼續(xù)之前，仔細(xì)檢查機(jī)車接線并確定每條線的位置和作用是很重要的。制造商的裝配圖在這里可能有用，或者您可以選擇創(chuàng)建自己的接線圖。特別是，您需要識別左側(cè)和右側(cè)電源拾取器的連接以及（+）和（-）電機(jī)連接。注：對于N、HO、S和O標(biāo)尺機(jī)車，正電機(jī)連接是連接到右側(cè)軌道（工程師側(cè)）電源拾取器的連接。在G級機(jī)車上，正電機(jī)引線連接到左側(cè)軌道拾音器（消防員側(cè)）。
導(dǎo)線
斷開通向兩個電機(jī)端子的所有導(dǎo)線。請注意，某些電機(jī)電刷連接使用彈簧觸點與底盤連接。在這種情況下，也需要拆除或修改彈簧觸點。請注意，某些機(jī)車可能僅在重新安裝車身時才會接觸電機(jī)和車架。接下來，使用電壓表或連續(xù)性測試儀驗證每個電機(jī)端子是否與左右導(dǎo)軌拾音器電氣隔離。將儀表設(shè)置為歐姆刻度后，將兩個儀表探針一起觸摸，注意儀表指示0歐姆（短路）。您不希望再次看到此指示！將其中一個探針接觸到其中一個電機(jī)電刷端子。將另一個探頭接觸機(jī)車機(jī)架，然后接觸左側(cè)軌道電源拾取線，最后接觸右側(cè)軌道電源拾取導(dǎo)線。將第一個探針移到另一個電機(jī)電刷端子并重復(fù)測試。如果所有測試均顯示開路，則電機(jī)已正確隔離。在完成此操作之前，不要繼續(xù)操作。
Isolate the motor Note this step
Because this is the most important step to successfully convert any locomotive to DCC operation. The two motor brush connections must be electrically isolated so that they are driven only by the DSD motor output. We're not kidding! Digital Sound Decoder User Manual 9 Stop Failure to properly isolate the motor will damage the decoder and turn it into an effective but short-lived smoke generator! Our warranty clearly excludes damage caused by improper motor isolation; However, if you corrupt the decoder, just return it to Throttle Up! Together with the service fee (please indicate the current amount), we will promptly repair and return it. Remove the boiler and bidding shell from the locomotive and bidding frame, and start the motor isolation. Before continuing, it is important to carefully check the locomotive wiring and determine the position and function of each line. The manufacturer's assembly drawing may be useful here, or you can choose to create your own wiring diagram. In particular, you need to identify the connections of the left and right power pickups and the (+) and (-) motor connections. Note: For N, HO, S and O scale locomotives, the positive motor connection is the connection to the right rail (engineer's side) power handler. On Class G locomotives, the positive motor lead is connected to the left track pickup (fireman side).
wireway
Disconnect all wires to both motor terminals. Please note that some motor brush connections use spring contacts to connect to the chassis. In this case, it is also necessary to remove or modify the spring contacts. Please note that some locomotives may only touch the motor and frame when refitting the body. Next, use a voltmeter or continuity tester to verify that each motor terminal is electrically isolated from the left and right rail pickups. After the meter is set to the ohm scale, touch the two meter probes together, and note that the meter indicates 0 ohm (short circuit). You don't want to see this instruction again! Touch one of the probes to one of the motor brush terminals. Contact the other probe with the locomotive frame, then contact the left track power pickup wire, and finally contact the right track power pickup wire. Move the first probe to the other motor brush terminal and repeat the test. If all tests indicate an open circuit, the motor is properly isolated. Do not continue until you have completed this operation.
