English LD-G-20 Load control At constant motor voltage, additional loads (e.g. running up a gradient, coupled carriages) cause the locomotive to slow down or even come to a standstill. If the load control is active the motor voltage varies to keep the locomotive operating at constant velocity at a given speed level, independent of additional loads.

LD-G-20 English Velocity characteristic The decoder can be adjusted to the driving characteristics of the motor and the characteristic speed of the locomotive type, by setting the starting velocity and the maximum velocity. From the starting velocity and the maximum velocity the decoder generates a linear velocity characteristic.
English LD-G-20 Function outputs The decoder has two function outputs which can be switched on and off via the function keys F0 to F8. They are available to connect optional accessories with a current of max. 100 mA (e.g. lighting).

English LD-G-20 Safe and correct soldering Caution: Incorrect soldering can cause dangers through fires and heat. Avoid these dangers by reading and following the directions given in the chapter Safety instructions. § Use a small soldering iron with max. 30 Watt. Keep the soldering tip clean so the heat of the soldering iron is applied to the solder point effectively.
LD-G-20 English Mounting the locomotive decoder Follow the connection diagram fig. 1. Connecting the motor Before mounting the decoder check if the locomotive motor´s current is below the maximum permissible value of 500 mA. If it is above 500 mA the decoder is not suitable for mounting in this locomotive.

English LD-G-20 If you want to use the decoder factory settings, you have to connect the lighting and the accessories as follows: Front lighting: white wire Back lighting: yellow wire Tip: Before starting to program the locomotive decoder you should connect the motor to the decoder.
LD-G-20 English Programming the locomotive decoder The locomotive decoder is programmed from the digtial central. See the chapter in the manual of your digital control unit where the programming of configuration variables (CVs) is explained. You can programm resp. read out the following locomotive decoder variables: NB.

LD-G-20 English § Parts are getting very hot and/or start to smoke. Tip: The deocder may warm up to 45 °C in operation. This does not affect the functioning of the decoder. Disconnect the system from the mains immediately! Possible cause: one or more connections are soldered incorrectly.
English LD-G-20 automatic recognition of the analogue mode during digital operation. Possible cause: The changing direction impulse for a Motorola decoder has switched the decoder to analogue mode. à If you simultaneously control DCC and Motorola decoders, it is advisable to switch off the automatic recognition of the analogue mode during digital operation.
