OPERATION
The green pilot light (Fig. 1) indicates that the locomotive
controller is ready to be used.
• Turn the control knob to the right or left in order to make
the locomotive go forward.
• Turn the control knob in the other direction to make the
locomotive go in reverse.
Stop/Halt Button
Press on the Stop/Halt button in order to stop all running
locomotive quickly. The track at this point has no voltage
present in it. All of the locomotive will run as they were
previously doing after you press a second time on the
Stop/Halt button.
Booster Button
Pressing on the Booster button will send the full available
power to the track. This allows you to “help“ a locomotive
with a heavy train on a mountain without have to adjust the
control knob.
Track Voltage Compensation (with a change in load)
The 51079 locomotive controller is equipped with a perma-
nently set track voltage compensation feature. When the
track current increases, the motor voltage in the locomo-
tives decreases due to voltage drop on the way from the
locomotive controller to the locomotive. This is automatically
compensated by an increase in the output voltage proportio-
nal to the track current from the locomotive controller.
Note: The locomotive operating voltage tracking function
works only when the speed control knob is not turned up full
since a voltage reserve is required.

red operating temperature is too high
blinking red short circuit, overload, or power shutoff with
the Stop/Halt button.
Overload Protection
This locomotive controller is equipped with short circuit
protection. In the event of an overload on the track or a
short circuit, the locomotive controller shuts off.
If your LGB transformer / switched mode power pack
provides less than 5 amps, the overload protection in the
transformer / switched mode power pack will be activated
in the event of a short circuit.
1. Short circuit: Correct the cause of the short circuit. Press
the Stop button in order to turn the locomotive controller
back on.
2. Overload: Take one or several locomotives off of the
track. Press the Stop button in order to turn the locomoti-
ve controller back on.
