General Information
Installation
The slave motor driver LP200 serves to expand the locomotive decoder LE200. It is used whenever a locomotive has two (or more) motors, and the maximum output current of the locomotive decoder LE200 or LE230 is not large enough for these motors. The slave motor driver then provides an additional 2 A of motor current.
Specifications of slave motor driver LP200:
Continuous load capacity of the motor output is 2 A
The motor output is short-circuit proof: a temperature sensor switches off the slave motor driver when there is an overload or short circuit. The locomotive decoder LE200/230 is also switched off at the same time.
Measurements: width 70 x depth 20 x height 12 mm (2 3/4 x 13/16 x 1/2 inches)
Preparations for installing the slave motor driver LP200
Before installation, the locomotive must be tested to ensure problem-free operation with regular DC power. Worn motor brushes must be replaced before installation. Only a mechanically fully fit locomotive will be able to operate without problems with locomotive decoder and slave motor driver.
Considerations for installation
The components of the slave motor driver must under no circumstances touch metal parts of the frame or shell of the locomotive. If they do, you will have a short circuit within the slave motor driver and it will be destroyed! The motor leads of the locomotive must not have any connections to frame or wheels of the locomotive.
The terminal row U+, T, S, R is solely for connecting the slave motor driver to the locomotive decoder LE200. The must be no connections to motor, rails or other terminals on slave motor driver LP200 or decoder LE200.
Important version note!
There are 2 versions of locomotive decoder LE200. On LE200 version 2 terminals M1 and M2 are reversed, as are G1 and G2. Therefore the connection of the slave motor driver varies depending on the decoder version. You can easily distinguish the versions of LE200: Version 1 has gray screw terminals, version 2 has green screw terminals and four round diodes on the circuit board. Please compare illustrations 1 and 2 to your decoder.
Connecting the slave motor driver

Connecting the slave motor driver to locomotive decoder LE230
- First wire terminals U+, T, S, R of slave motor driver LP200 with the corresponding terminals on locomotive decoder LE200. Then connect terminals G1 and G2 of the slave motor driver with the corresponding terminals on locomotive decoder LE200.
- Now connect the first motor to terminals M1 and M2 of the locomotive decoder, then connect the second motor to terminals M1 and M2 of slave motor driver LP200.
- You must not connect the motor output M1 and M2 of the slave motor driver in parallel with motor outputs M1 and M2 of the locomotive decoder! This will cause the failure of both units.
- Test for correct connections, while programming the locomotive decoder.
- When connecting the motors, make sure that the motors turn in the correct direction on command "forward move." If that is not the case, you must reverse the motor leads on the slave motor driver LP200.
