6.9.6.2. Reed switch sensor
If you have trouble obtaining a hall sensor IC, you may also use
a subminiature reed switch. They are connected to the decoder
with two pins only.
However, their sensitivity is not as good as hall IC sensors and

stronger magnets may be needed in order to trigger these reed
switches correctly. Furthermore the position of the reed switches
needs to be considered.
6.10. Connecting Capacitors
On many older layouts, current pick up of locomotives is not very
reliable. Therefore, power interruptions may cause a stop or jerky
movement when the locomotive travels over turnouts at low
speeds. This can be overcome with buffer capacitors (100 mF /
25V or higher show the desired results). If desired you may con-
nect them to the LokSound decoders.
Soldering wires onto a decoder requires quality soldering equip-
ment and experience. Our warranty does not cover damage
caused by inappropriate soldering. Consider carefully if you re-
ally need that capacitor.
6.10.1. All LokSound decoders
You can connect two larger capacitors as per the circuit in the
upper half of figure 14.
The capacitor is charged via a resistor (100 Ohms) thus preventing
the digital system from interpreting the charging current as short
circuit at the time of switch-on. The diode makes sure that the
energy of the capacitor is fully available when required.
However, you may not run this locomotive on AC layouts any-
more. Risk of destruction!
Disconnect / remove the capacitor prior to programming with
the ESU LokProgrammer!
6.10.2. Optional "PowerPack"
You can solder a powerful energy buffer to all LokSound V4.0 H0
decoders. In the lower half of figure 14 we show you how to do
it. This „PowerPack" allows your locomotive to keep running for
2 seconds without power.
