Suitable Bulbs; Micro Incandescent Loksound 5 Xl - Esu LokSound 5 Installation And Operating Instructions Manual

Installing the decoder
When using a special light bulbs is must be observed: On power this much
current need ( "cold flow") that becomes lower after a short time. In particular,
the use of 12V bulbs can therefore happen that when switching on the lighting
this "twitches" briefly and then the outputs are switched off by the decoder. The
lights will be switched on briefly and off again at 1-second intervals. This is due
to a large surge of bulbs, the decoder can not separate sub of an overload.
Therefore, it is important to install the correct bulbs.
6.10.1.1. suitable Light bulbs
Use only 16 V bulbs or higher and a maximum nominal current of 50mA.
In many older ROCO® and Fleischmann® locomotives 12V pear surfaces are
installed. This not only require a lot of power, but become extremely hot during
operation and can cause damage to the locomotive. Replace them with 16V
bulbs.
6.10.1.2. Micro bulbs LokSound 5 XL
The LokSound XL decoder 5 enables direct operation of micro incandescent
lamps. For this purpose, a separate voltage regulator on the decoder is installed.
This provides factory, a voltage of 1.8V, which is designed for long life of
3VBirnchen. To do this, do not lead to the return conductor of the Birnchens to U
+ but to the marked "Uvar" terminal.
You can change the voltage of the regulator by replacing a resistor. You need a
SMD resistor, size 0805, 0.125W with the following values:
voltage R124
1.5V 33 kilohms
2.5V unsolder
3.0V 48 kilohms, Unsolder R125
The maximum load de Uvar output is 500mA.
