M.T.H. ELECTRIC TRAINS
7DASH 9 DIESEL ENGINE
This engine is equipped with a coil-wound Proto-Coupler 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.
Rear Coupler: To fire the rear coupler, press the Bell button once followed immediately
by three pushes of the Horn/Whistle button. The sound of the lift bar and air line
depletion will play, and the knuckle will be released.
Front Coupler: To fire the front coupler, press the Bell button once followed
immediately by four pushes of the Horn/Whistle button. The sound of the lift bar and air
line depletion will play, and the knuckle will be released.
PROTO-COUPLER ®OPERATION
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 release of cars while on the
run. To maintain a constant speed when speed control is turned off, you need to adjust the
track voltage yourself. When speed control is off, the volume will drop to allow for better
low voltage operation. Full volume is restored upon reactivation of speed control.
To turn speed control on and off: First, put the engine in neutral, then press the
transformer’s Horn/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 Horn/Whistle, 2 bells code to return it to the other state. You will want to do this during
the initial neutral start-up if you ever couple this engine with another engine that is not
eqipped with speed control to avoid damaging the motors in either engine. Each time
you shut down the engine completely, it will automatically turn speed contol on.
SPEED CONTROL
You can lock your engine into a directional state (forward, neutral, reverse) to prevent
it from changing directions. To do this, put the engine into the direction you want or in
neutral, run it at a very low speed (<10 scale mph), and quickly but firmly press your
remote’s Horn/Whistle button once followed immediately by three presses of the Bell
LOCK INTO A DIRECTIONAL STATE
