1. Important notes – Security issues
This product is not a toy! It is not recommended for children under
14 years. Unsuitable for children under 3 years: small parts
could be swallowed! There is a risk of injury in case of incorrect
use because of sharp edges and points. Keep this instruction for
later use. The light bar is solely designed to be used within
electrical model railroads. You must not use it in other ways.
Warning: Mounting the light bar is only to be done with the
operating power switched off. There must be no contact between
electronic parts or unused cables of the light bar and metal parts
of the model railroad car or the track.

2. Features of the light bar

2.1.

Analogue mode

This light bar may be used in analogue operated DC and AC model
railroads. With a supply voltage of at least 4 ... 5 V the embedded
microcontroller automatically recognizes the correct operation
mode and switches the LEDs on. Because of the embedded
constant current circuit the LEDs light at full power from about 7 V
and above. Use the potentiometer on the light bar to adjust the
brightness to the needs of your installation. There might be some
flickering if the brightness is calibrated low. You prevent this by
attaching a buffer capacitor of a adequate size. One big benefit of
the LH10 is that certain functions (blinking, randomly switching the
light on and off) may be set (programmed) in digital mode (e.g. at
your dealers shop) and then be used in your analogue model
railroad environment.
2.2.

Digital mode

Because of the embedded multiprotocol decoder the light bar
LH10 may be used on your digitally operated model railroad
without change. The decoder detects the correct data format (DCC
or Märklin®) automatically. There are a lot more things you can
adjust than only 'On–Off': you can regulate the brightness of all or
solely of single outputs. You can define certain outputs to be
randomly switched on and off. There are some additional outputs
at the end of the light bar. These are designed for the taillights but
can also be used for the change of the headlights in a control car.
Even the control of digital decouplers is possible. Of course it is
possible to read the values of the decoder CVs (with a proper
central station).
2.3.

Buffer capacitor

There is not much room in the roof bowing of a lot of model
railroad cars. That's why we built the light bar very slim and omitted
backup capacitors. If you encounter the problem of flickering light
you can easily mount a supplementary buffer capacitor at the
marked pins and 'hide' it within the car. The toilet is a favoured
place for that. There is a current limiter for this special use on the
LH10. Specially in digital mode it protects the central station from
high switch on currents.
