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. 29) 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.

NOTE:

The software code used to operate the Lenz-style electrical couplers is different

than the software code used for the MTH Proto-Coupler. If  your model came equipped
with the Lenz-style coupler DO NOT install an MTH Proto-Coupler without updating the
DSP code. Like wise if  your model came equipped with an MTH Proto-Coupler, DO NOT
install the Lenz-style coupler without updating the DSP code. Damage may occur to the
coupler or the PS 3.0 board. If  you desire to change the type of  electrically operated coupler
on your locomotive, you can load the appropriate DSP Code for the new coupler using the
MTH DCS control system and a PC.. You will need a TIU running software version 4.20 or
higher and the Consumer Loader version 2.3 or higher.

Tips on Using PFA

• 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.
