Premier P5-a Electric Engine
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. You can fire the coupler(s)
from neutral or while in motion. Use the codes shown below (and in the chart
on pg. 5) to fire the coupler(s).
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, 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.
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 maintain a constant speed
when speed control is turned off, you need to adjust 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,
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.
