Conversion of a 3-lead LGB gear box to digital operation Old LGB gear boxes feature 3 leads, one pin (marked WS) is connected to track power and one of the two motor connectors. For digital operation the motor connector must be separated from this pin. The pictures show a simple conversion for digital operation: open the gear box and remove the electric motor (note the direction) shorten the motor contact…
Before digitalization of a loco you have to select the right decoder. Manufacturer’s data of current draw are not available in most cases or it is not reasonably usable. So it make’s sense to build a small measuring equipment for each loco, to measure the current. You need: (see picture) A LGB-transformer with apr. 22V(alt. a power supply) A meter for current measurement (Multimeter or analog instrument) . A…
To control a switch automatically with a 1 channel switch decoder, following circuit can be used. You will need 2 track contacts, a 1 channel switch decoder and locomotives with mounted magnet on the gear side. Here is a diagram of how everything should be connected: In this combination, the switch is automatically moved into the correct position before leaving the reverse loop. Note the polarity of the contact…
The interface consists of two socket strips, of which however only one is used (see locomotive instructions) Again, you can easily connect a decoder Massoth with the basic functions (motor + lights). You need a 12-pole pin strip, which is connected to the decoder according to the plan below. The interface is symmetrical except for the two inner pins 6 + 7. The 4 external connections (track +/-) should…
Here is a connection diagram for the Saxonian IV / k. You can use that diagram also for XL decoder. You can solder the cables simply to the sockets on the PCB. Program CV64=0 and CV54=7. Then the smoke generator is switchable with function key 7. here is the connection diagram for one-engine locos.
You can also connect a XL/XLS Decoder to a Brawa Interface. Therefore you need two 9-pole plug connectors. Connect them like described below. Following special functions of the loco are usable. Light : Swiss illumination (3+1) in both directions. F1 : Light cabin F2 : Shunting lights (3+3) F3 : Smoke unit (CV115=3 parallel output F4 on key 3) Because of the higher amperage of the smoke unit F3+F4 are connected parallel. Alternatively,…
Attached you can find a plan howto connect a L decoder at a LGB interface cable.
If you have old 3-pin Switch-drives from LGB, you can control this with our 4 channel-switching decoders. Here is a sketch how to connect it: The switching time should be set down a little in CV 51-58 (Value 66).
Sorry, this entry is only available in German.
If you would like to control the Uncoupler with the outputs A5-8 from the XL / LS / XLS, you need a small additional circuit for controlling the Uncoupler. See picture with schematic. The circuit can be easily mounted on a stripboard. P.S.: The L decoder does NOT require this circuit!
