le knob to the left, beyond the
spring-loaded "Off" position, to
change the direction of travel.
The two yellow LEDs indicate the
polarity of the tracks. Their inten-
sity increases with increasing
track voltage.
Boost button
Press the Boost button to increa-
se the track voltage to the maxi-
mum value. Now your locos acce-
lerate with the programmed acce-
leration (see
acceleration and braking). After
you release the Boost button, the
locos brake with the programmed
deceleration, until they reach the
speed selected with the throttle
knob.
Stop/Halt button
Press the Stop/Halt button to slow
your locos according to the pro-
grammed braking deceleration
(see Programming acceleration
and braking), until they stop.
After you release the Halt/Stop
button, the locos accelerate as
programmed, until they reach the
speed selected with the throttle
knob.
Programming
acceleration and braking
You can program acceleration
and braking after switching to a
different throttle knob range and
before you activate the new thrott-
le range. Follow the steps shown
in Figure 2.
Hints:
- Program the throttle in "Left Off"
mode only. Otherwise, the thrott-
le will be activated when the
throttle knob is turned beyond
the "Center Off" position during
programming. This will abort the
programming.
- You can program acceleration
and braking separately. The
other value remains program-
med until it is reprogrammed.
- All values remain programmed
when the throttle is switched off
or when the throttle range is
switched.
Load compensator
The 51070 throttle is equipped
with a non-adjustable load com-
pensator. With increasing power
consumption,
decreases due to losses between
throttle and locomotive. The

Programming
motor voltage
throttle automatically compensa-
tes for this by increasing the out-
put voltage proportionally to the
output current. With this feature,
trains travelling at low and medi-
um speeds display a much more
even speed, whether going uphill,
downhill or around curves. The
load compensator also prevents a
speed decrease when an additio-
nal train enters the track block.
Hint: The load compensator
works only:
- if the throttle knob is not on the
fastest setting and
- if a transformer with an output of
18 V AC or 24 V DC is used.
Wireless Control
You can
55055/55056 Wireless Receiver
to the 51070 throttle. Then you
can control direction and speed
("Center Off" mode) of your trains
from anywhere on your layout,
using the 55016 Loco Remote
(with 55050/55051
Transmitter). (You can also use
the 55015 Universal Remote.)
Overload Protection
The throttle is protected against
short circuits. If a short circuit
occurs, the throttle will switch off.
However, this overload protection
functions only when using a
power supply with an output of 5
amps or more.
When using an LGB power supp-
ly with an output of less than 5
amps, a short circuit will trigger
the overload protection of your
power pack (see Power Supply).
Attention! If there is a short cir-
cuit or overload, unplug the power
supply from the house current
outlet immediately:
1. Short circuit: Find and remove
the short circuit. Reconnect the
power supply cord. Reset the
throttle by turning the throttle
knob to the "Off" position.
2. Overload: Remove one or
more locos from the track.
Reconnect the power supply
cord. Reset the throttle by turning
the throttle knob to the "Off" posi-
tion.
Power Supply
Attention! For safety and reliabi-
lity, operate this product with LGB
power supplies (transformers and
power packs) only. With other
