LokPilot XL V4.0 - PowerPack for outdoors

Further information

The biggest of all LokPilot decoders is truly the new LokPilot XL V4.0. It speaks DCC with RailCom-Plus®, Motorola®, Selectrix® and M4 as well as auto-detection. With its high motor-output performance, 8 function and 4 servo channels as well as an integrated PowerPack it is perfectly made for outdoor railway and large scales. Screw terminals make a simple instalment possible.

Operational modes

The LokPilot XL V4.0 is multi-protocol decoder meaning it speaks all common data formats such as DCC, Motorola® and Selectix®. In DCC mode 14-128 speed steps are possible, as well as 2- and 4-digit addresses. You can activate up to 28 functions. Thanks to RailComPlus®, the decoders will be automatically recognised by a suitable command station (e.g. ECoS). It is able to control all DCC programming modes und thus can be driven and programmed by all DCC-compatible digital command stations. CV values can be read out on the main track with corresponding command stations, thanks to RailCom®. There are indexed CVs for command stations which are only able to program CVs from 1-255 (e.g. ROCO® Multimaus). Motorola® users benefit from up to 28 speed steps with 255 addresses. Three further Motorola® addresses allow the activation of 16 functions. The installed programming mode makes re-programming with the venerable Control Unit® 6021 also possible. The M4 protocol ensures an automatic recognition of the decoder by mfx®-compatible command stations (e.g. Märklin® Central Station or mobile station®). Reprogramming of M4 decoders is still possible with the mentioned command stations, like with original Märklin® decoders. ESU is a 100% compatible. The LokPilot XL V4.0 decoder auto-detects the known Märklin® braking sectors as well as the ZIMO® HLU braking commands or the Lenz® ABC system. Braking with DCC brake generators or with DC (“Brake on DC”) is supported. Furthermore you will be able to stop your train by using the Selectrix® braking diode.  The LokPilot XL 4.0 decoder can be used for both, analogue DC or AC locomotives. The motor control function is teaching the motor »good manners«. As you would not expect anything else from ESU decoders, the decoder automatically switches between the different operating modes “on-the-fly”. In most cases one does not have to adjust anything. 

Motor control

The LokPilot XL V4.0 decoder is equipped with fifth generation load compensation. The control frequency can be adjusted – if so desired - to the speed and facilitates an even better, very soft, absolutely silent drive with most motors. Load control can either be adjusted to the model manually with the aid of 5 parameters or by using the “auto tune” feature of the decoder. This results in automatic adjustment of the motor characteristics in a test run. Its motor output can handle up to 4.0A (even 5A for a short time). Thus there will be enough steam for PIKO® locos or heavier two-motor engines. The LokSound XL V4.0 is able to control all known motors in the G gauge or outdoor railway sector, especially Mabuchi®, Bühler® or Faulhaber® without any problems. With Dynamic Drive Control (DDC) you can limit the influence of load control and thus you will be able to finely control your locomotive in the yard and when traversing turnouts while the speed will be prototypically reduced while travelling (at higher speeds) on a gradient on the mainline. 


Since we know that there is a lot to switch in large scale locos we equipped the decoder with function outputs for lights as well as 4 additional servo outputs for coupling, pantographs or other mechanical toys. Of course, the decoder generates all power required itself. All important light functions are available. The brightness of each output can be adjusted separately. Of course, the decoder is able to control the automatic decoupling move and push time for ROCO®, Krois® and Telex® couplers.

Safe operation

Like its forerunner, the LokPilot XL V4.0 also has an energy storaging PowerPack directly soldered on its board. It helps small locos with a small number of axles to “rush” easily over dirty spots.


Of course, all function outputs and the motor current output are overload protected. We want you to have fun with your decoder as long as possible!
