USRA 0-6-0 STEAM ENGINE
This locomotive 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 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 auto-
mobile 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 Whistle button one time then immediately press the Bell button two times. Two
whistle 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 start-up if
you ever couple this engine with 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.
SPEED CONTROL
You can lock your engine into a directional state
(forward, neutral or 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 Whistle
button once followed immediately by three presses of the Bell button. Two whistle 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 whistle, 3 bells code to return the engine to its normal
state, even if the engine has been kept without power for extended periods of time.
