Proto-Coupler Operation; Speed Control - M.T.H. Premier Bavarian Class 3/6 Express Operator's Manual

•You can terminate PFA at any time by turning off power to the track for 15 seconds.
•You do not have to be in Forward to use PFA. At the conclusion of the full sequence,
the train will pull away from the station or yard in whatever direction you were going
when you activated the feature.
•You can use PFA even if you are double-heading with another engine. If the second
engine is not equipped with Proto-Sound 3.0, you must remember not to leave the
throttle at a high voltage level once you have stopped the engine to run the PFA.
Otherwise, the engine without PFA will begin vibrating on the track as its motors strain to
move the train, since they cannot be automatically disabled during the PFA cycle (or if an
original Proto-Sound engine, PFA are triggered differently and that engine's motor-
disable feature will not be active when you run PFA in Proto-Sound 3.0).
•PFA can be triggered from Neutral. It will operate the same as if triggered while in
motion except that, at the conclusion of the PFA, the engine will depart in the next
direction of travel, as opposed to the direction it was traveling before entering Neutral.

Proto-Coupler Operation

This locomotive is equipped with one or more coil-wound Proto-Couplers for remote
uncoupling action. Because Proto-Couplers are controlled through the Proto-Sound 3.0
microprocessor, they do not require an uncoupling track section or modification to your
layout to function. You can fire a coupler from neutral or while in motion. Use the code
shown below (and in the chart on p. 30) to fire the coupler(s).
Rear Coupler:
To fire the rear coupler, quickly tap the Bell button once followed by three quick taps of
the Horn 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 (if your engine has one), quickly tap the Bell button once
followed by four quick taps of the Horn 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 3.0 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.
