Proto-Coupler® Operation
This locomotive is equipped with two coil-wound Proto-Couplers for remote
uncoupling action. Because the Proto-Coupler is controlled through the Proto-
Sound 2.0 microprocessor, it does not require an uncoupling track section or
modification to your layout to function. Use the codes listed below to fire the
coupler.
Rear Coupler:
To fire the rear coupler, press the Bell button once followed immediately by
three pushes of the Whistle button. The sound of the liftbar and air line
depletion will play, and the knuckle will be released.
Front Coupler:
To fire the front coupler (if your engine is equipped with one), press the Bell
button once followed immediately by four pushes of the Whistle button. The
sound of the liftbar and air line depletion will play, and the knuckle will be
released.
Note:
There is a coupler switch on this engine for use with a Dummy Unit. The
switch chooses between rear coupler of power unit and the Dummy Unit.
Speed Control:
M.T.H. engines equipped with Proto-Sound 2.0 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.
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.
To turn speed control on and off
, put the engine in neutral, then press the
transformer’s Whistle button one time then immediately press the Bell button
two times. Two horn blasts will indicate that the engine has made the change.
Repeat the 1 whistle, 2 bells code to return it to the other state.
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.
