To install:

The 52121 is designed for installation in control panels or similar applications. To install the 52121:

  1. Drill a hole (diameter at least 6.5 mm, 9/32 in) for the axle of the throttle knob. Pull the throttle knob and the graduated dial face off the unit.
  2. Drill two holes for the mounting screws. insert the axle of the throttle knob from below through the hole drilled in step 1. Use two M3 screws to secure the throttle from above. Attention! The screws must not protrude more than 4 mm (3/16") from the heat sink. if hey protrude further or press on the circuit board, the circuit board will be damaged.
  3. Glue the graduated dial face onto the face of the control panel and press the throttle knob onto the throttle.

Attention! Make sure the heat sink is ventilated . If the throttle is installed in an exclosed housing, provide adequate ventilation holes. When installing several throttles 52121 next to each other, make sure there is a space of at least 5 mm between the heat sinks.

To Wire:


The throttles can be connected to AC or DC power from any LGB power Supply. An internal circuit automatically detects the power type and converts it to track power. Connect the power supply to the terminals on the right side of the throttle (marked WS/SW).

Connect the track to the terminals on the left side (marked RT/BL).

Hint: The throttle can also be used with two 12 volt automotive or "deep cycle" battery. For safety, also use a regular automotive fuse rated up to 4 amps. When connecting to a 12-volt car battery, the circuit must be protected via a 4 A fuse, (e.g . car in-lead fuse holder as used for car radios).lf a fuse is not fitted, the electronic controller will be damaged.

Attention! Connect the throttle using wires with a cross-section of at least 0.5 mm2 (20 AWG) (e. g., LGB 50160 or Shourt Line 18 AWG red/black automotive zip cord)

To Operate:

When the throttle knob is in the center ,,0" position, the throttle is off. Turn the throttle left or right to change the speed and direction of the train.

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 supply 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 circuit 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 center ,,0" position for at least 2 seconds.
  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 center "0" position for at least 2 seconds.
