Speed Control
M.T.H. engines equipped with Loco-Sound have speed control capabilities that allow the
engine to maintain a constant speed up and down grades and around curves, much like an
automobile cruise control. You can add or drop cars on the run, and the engine will
maintain the speed you set.
The engine is programmed to start with the speed control feature activated, you can opt to
turn it off. This means the engine's speed will fall as it labors up a hill and increase as it
travels downward. It is also affected by the addition or releasing of cars while on the run.
Because the engine will run more slowly at a given throttle voltage when speed control is
on than when it is off, you should adjust the throttle to a lower power level for operation
with speed control off to avoid high-speed derailments.
To turn speed control on and off,
put the engine in neutral, then quickly tap the
transformer's Whistle button one time then quickly tap the Bell button two times, allowing
approximately ½ second to lapse between each quick button press. Repeat the 1 whistle, 2
bells code to return it to the other condition.
You will want to do this during the initial
neutral upon start-up if you ever couple this engine to another engine that is not
equipped with speed control to avoid damaging the motors in either engine.
Each
time you shut down the engine completely, it will automatically turn speed control on.
Direction Lock
You can lock your engine into a direction (forward, neutral, or reverse) so that it will not
change directions. To do this, put the engine into the direction you want or into neutral, to
lock it into neutral, run it at a very slow crawl (as slowly as it will move without halting),
and quickly but firmly tap the Whistle button once followed by three quick taps of the
Bell button, allowing approximately ½ second to lapse between each quick button press.
The engine will not change direction (including going into neutral) until you repeat the 1
whistle, 3 bells code to return the engine to its normal condition, even if the engine is kept
without power for extended periods of time.
