Premier Dash 9 Diesel Engine Operating Instructions
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, quickly tap the Bell button once followed by three quick
taps of the Whistle button, allowing approximately ½ second to lapse between each
quick button press. The sound of the liftbar and air line depletion will play, and the
knuckle will be released.
Front Coupler:
To fire the front coupler, quickly tap the Bell button once followed by four quick
taps of the Whistle button, allowing approximately ½ second to lapse between each
quick button press. 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 turn speed control on and off, put the engine in neutral, then
quickly
tap the
transformer’s Whistle 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 whistle,
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. Note: When speed control is turned off, the Proto-Sound 2.0
system will limit the volume in order to operate more smoothly at lower voltages.
Full volume is restored upon reactivating speed control.
