LD-G-1 / LD-W-1Englishfig. 3a) or you must connect the second side of the lamps according to fig.3b to the return conductor (point X3 on the front of the decoder).Connect other accessories (e.g. smoke generator, cab lighting), which areswitched by the functions F1 to F4, to the points X7 to X10 (front of thedecoder). You can connect the second side of the accessories either tothe return conductor (point X3) or to locomotive ground. If connectingthe accessory to locomotive ground you must solder in a diode.! Caution:The return conductor for all functions (point X3) must under nocircumstances be connected to locomotive ground. Possible shortcircuit! The locomotive decoder will be damaged in operation.Tip: If the second side of the lamps is connected to locomotive groundthe lamps often flicker in operation. You can avoid the flickering of thelamps if you connect the second side to the return conductor (point X3)instead of locomotive ground.! Caution:If you connect the loads to the return conductor for all functions (pointX3), the load must be insulated. The loads must not make contact withmetal parts of the locomotive. Possible short circuit! The locomotivedecoder will be damaged in operation.Connecting the LEDsThe function outputs of the locomotive decoder switch against decoderground. For that reason you must connect the cathode (-) of the LED tothe output of the relevant function.! Caution:If you use light-emitting diodes (LEDs) you must always operate themvia a series resistor.LEDs are available in many different models. There are LEDs with 2-5mA, but also LEDs with 15-30 mA power consumption. The seriesresistor limits the current flow of the LED and will need to be calculatedfor each model. Ask for the max current rating when buying your LEDs.Page 29
EnglishPage 30LD-G-1 / LD-W-1You can connect several LEDs in parallel to each output. In this case everyLED must have a series resistor of its own. If you connect several LEDs toone output in series, only one series resistor is needed. The number ofLEDs connected in series to one output depends on the digital voltage.You can determine the number of the LEDs that can be connected inseries to one output from the following formula:(number of LEDs + 2) x 1,5 < digital voltageFixing the locomotive decoderAfter completing all connections fix the locomotive decoder with doublesidedadhesive tape, for example.Using an NEM 652 interface connectorContact Connection Colour of cable Connecting points1 Motor connection 1 orange X112 Lighting back (-) yellow X53 Not used or F1 green X74 Power supply left black X15 Motor connection 2 grey X126 Lighting front (-) white X47 Common conductor blue X3for all functions (+)8 Power supply right red X2Some locomotives already have an NEM 652 interface connectormounted. Using a convenient connecting plug you save disconnectingthe connections and you do not need to solder at the locomotive.The list shows how to connect the contacts of the interface connectorto the connecting points of the locomotive decoder.Setting the locomotive decoderSetting the driving characteristicsDifferent driving characteristics can be fixed for the locomotve decoder:
