BL-2 Diesel Engine
12
While 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. When speed control is
off, the volume will drop to allow for better low voltage operation.
To turn speed control on and off
, put the engine in neutral, then quickly tap the
transformer’s Horn button one time then quickly tap the Bell button two times, allowing
approximately ½ second to lapse between each quick button press. Two horn blasts will
indicate that the engine has made the change. Repeat the 1 horn, 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.
Locking Locomotive Into A Direction
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 halt-
ing), and quickly but firmly tap the Horn button once followed by three quick taps of the
Bell button, allowing approximately ½ second to lapse between each quick button press.
Two horn blasts will indicate that the engine has made the change. The engine will not
change direction (including going into neutral) until you repeat the 1 horn, 3 bells code
to return the engine to its normal condition, even if the engine is kept without power for
extended periods of time.
