6.6.4.2. Connecting Universal Motors with HAMO-Conversions
Do not wire universal motors installed in many older Märklin®
locomotives (also known as AC motors) directly to LokPilot
decoders. You must modify the motor by first installing perma-
nent magnets – so called HAMO magnets. You may purchase
these magnets from your ESU dealer.
We supply three types of magnets. Please refer to chapter 18.2.
for more information regarding motor conversions with perma-
nent magnets.
6.7. Connecting Additional Functions
You can wire any kind of load such as light bulbs, LEDs (light
emitting diodes), smoke generators or similar devices to the
function outputs provided the maximum current draw is less than
that of the decoder output.
The permitted maximum current draw per function output is listed
in chapter 20 under „Technical Data.“
Please make sure that the load does not exceed the permitted
maximum current and there are no short circuits. The outputs
of the LokPilot have protection but if an external voltage is
applied, the outputs may suffer damage or destruction.
6.7.1. Overload Protection of Function Outputs
The function outputs of LokPilot decoders have electronic
protection against overload and short circuit. The decoder keeps
checking the sum of all function output currents. If the current
is too high, the decoder will switch off the outputs. After about
1 second, the decoder tries to switch them on again. Should the
current still be too high – perhaps due to a short circuit – the
same procedure starts again.
When using light bulbs (incandescent lamps) please note the
following: they draw a very high „inrush current“ when they are
switched on, that becomes lower after a few moments. Therefore,
it can happen with 12V bulbs that the headlights „flash“ briefly
during switch-on and then extinguish due to the overload
protection of the decoder. It is important to install the correct
bulbs.
6.7.1.1. Suitable Light Bulbs
Only install bulbs rated 16V or higher and with a nominal current,
that does not exceed 50 mA.
Many older models by ROCO® and Fleischmann® have 12V bulbs
installed. They draw a high current, become very hot, and may
cause damage to the locomotive. Replace them with 16V bulbs.
6.7.2. Connecting the Light Outputs as well as AUX1 and AUX2
This procedure depends on the wiring of the lights and auxiliary
functions in the locomotive:
a) The lamps / function outputs are insulated from the common
pole (ground) (i.e.: the locomotive chassis); therefore they are
potential free. Fig. 4 shows the correct wiring for the outputs
AUX1 and AUX2. The functions of the locomotive must be po-
tential-free, in other words there may not be any other connection
to the function besides the wires from the decoder. The voltage
at these outputs is about 1.5V lower than the track voltage. The
blue wire is the „plus-pole“; the function output the „minus-
pole.“
If LEDs are installed (also refer to Fig. 4, output AUX1), then a
resistor must be wired in series with the LEDs. It should have a
