Locomotive decoder LE230
The DIGITAL plus locomotive decoder LE230 is suitable for all DC motors in
S Scale or larger locomotives with continuous current draw of 2.5 Amps or less.
The characteristics of the decoder are:
∗
Control of the motor's rotational speed (load compensation). Regardless of
the load, the motor's rotation speed is kept nearly constant. During extremely
slow movement (for instance through sharp curves and over a series of
turnouts), LE230 always provides the motor with enough voltage. This creates
the impression that there is actually 100 tons moving.
∗
Selectable for operation with 14/27, or 28/55 speed steps.
∗
Optional operation on conventional DC layouts is possible.
∗
Provides 2.5A continuous motor current.
∗
8 switchable function outputs (includes 2 for directional lighting) that can be
connected directly or through Function Module LF200 (depending on the
current draw) + 2 additional function outputs controllable through the LP200
auxiliary motor module.
∗
Support for Advanced Consist Control and Extended Addressing
∗
Support for short form programming on the main for acceleration and
deceleration trim
∗
Support for all form of programming as described in NMRA RP-9.2.3
∗
Programmable locomotive address, acceleration and brake momentum,
speed curve and much more.

Size: L 2.75" x W 1,18" x H 0.50"

Summary of Contents for Lenz DIGITAL plus LE230
- Page 1 Locomotive decoder LE230 The DIGITAL plus locomotive decoder LE230 is suitable for all DC motors in S Scale or larger locomotives with continuous current draw of 2.5 Amps or less. The characteristics of the decoder are: ∗ Control of the motor’s rotational speed (load compensation). Regardless of the load, the motor’s rotation speed is kept nearly constant.
- Page 2 Locomotive decoder LE230 The features of the LE230 Decoder The LE230 has been revised and is packed with features you expect in a high end decoder. Advanced consist control, extended addressing, outstanding 28 step motor control, and 10 function outputs (includes two for directional headlight control) are but a few examples.
- Page 3 Locomotive decoder LE230 Back EMF Control The LE230 uses a form of motor control called "back emf" control. All DC motors produce a small amount of current when they are rotating. The amount of current produced is a function of the load that the motor is controlling. The LE230 measures this current and is able to adjust the current to the motor based upon the motor load.
- Page 4 Locomotive decoder LE230 can be safely operated with this transformer. Normally 18V is the highest allowed effective transformer voltage: 26V / 1.4 = 18V Operation with an electronic controller: For electronic controllers, you cannot determine the maximum output voltage through a simple formula. It is simply not enough to use the maximum output voltage of the transformer that supplies the electronic train controller! Contact the manufacturer if you do not find any indications in the operation manual.

Page 5: Installation Considerations
Locomotive decoder LE230 Mathematically the sum of all the maximum currents is greater than the allowable total current of 2.5A – this in order to allow customized use of the decoder –, but even so this value must never be surpassed in continued operation. An example: You need a motor output current of 1.5A for the operation of the motor. - Page 6 Locomotive decoder LE230 limits of the LE230. There must not be any other connections created to the motor, track, or other terminals on Locomotive Decoder LE230. The different installation options For connecting Locomotive Decoder LE230 there are several options, all depending on if you intend to connect the functions in the locomotive (as shown in illustration 1) with their common lead connected to a rail wiper, or (as in illustration 2) isolated (isolated from contact with wheel wipers and frame/shell).
- Page 7 Locomotive decoder LE230 ∗ Terminal L2 to the rear lights (in direction of travel). If the lamp is isolated, then connect terminal U+ with the other lamp lead. Now put the locomotive (without putting on the shell) on the programming track, and read out the address. From the factory the decoder is programmed to address 03.

Locomotive decoder LE230 Read out CV30. In this CV (when the self-test is on) the type of problem is stored as the corresponding bits. From the table “Determining the settings of the Locomotive Decoders in CVs” you can read which bit shows which problem. Now again remove the locomotive from the track, correct the problem as needed and test it again. - Page 9 Locomotive decoder LE230 Connecting Slave Motor Driver LP200 The plug-in terminal row S2 is intended for this. The wire colors are assigned as follows: blue yellow green Two additional wires are provided for controlling F7 and F8. For detailed information on installation and wiring, please refer to the operation manual for the LP200.
