Pressing the help       button on the Drive Window will bring up the 

Function Help Window. This screen displays all available function 

buttons, what they do, and their status (on/off). This feature will only 

display named functions for each function number if the selected 

locomotive has a roster entry whose functions have been defined in

.

Programmable Buttons 

There are nine buttons on the LT-50 that can be assigned operations 

by the user. These buttons can be customized to perform an operation 

different from their default assignment. The one, two, three, and 

four “dot” buttons will always identify their action with an on-screen 

description. If the description is blank, no action is assigned to that 

button. 
You can access button configuration 

options via the “Throttle Settings” 

menu (       , 8, 1, 1). The programmable 

buttons will adjust based on the settings 

in your throttle and selected locomotive’s 

roster entry (if the selected loco has a 

roster entry). If you select a locomotive 

without roster data, the buttons will return 

to their defaults and/or will not display 

function names.
The ninth programmable button is used by pressing down the knob. 

Maximum Number of Locos

The nominal current limit of the LT-50 is 1.4A continuous. The LT-50 

will shut off automatically once a set thermal cutout is reached, and will 

automatically resume once it has cooled down. Below, we have included 

a table for some examples of exaggerated load values which can help 

you determine approximately how many individual locomotives you can 

operate simultaneously. Note that you will likely be able to run more than 

the specified Maximum. Your loads/results will vary.
