E-33 Rectifier Operating Manual
In order for Proto-Sound® to properly initiate the system check, do not
advance the transformer throttle past 10 volts when you first enter RESET,
wait for the electric startup sounds to begin and then slowly turn the
transformer throttle to the off position and then back on again to enter the
forward phase. Interrupting the power too quickly may cause the system to
re-enter RESET (signaled by two dings of the bell). Should this happen,
wait longer before interrupting the power to enter the Forward phase.
Proto-Sound® comes with several programmable functions, including
Engine Volume Adjustment, Separate Bell Button Operation
(pre-programmed at the factory), Cab Chatter On/Off Control, ProtoCoupler
On/Off Control and Horn-In-Neutral Operation. Each of these features are
described in more detail later. You will notice that when in RESET, your
engine will not respond to the whistle button with a horn blast or continuous
bell ringing. In fact, when in RESET and the whistle button is depressed,
only one single bell chime will be heard each time the whistle button is
pressed. If you don’t want to configure or change your locomotive using
any of these programmable features, simply leave RESET and wait 2.2
seconds before interrupting the power to put the engine in forward. After
you leave RESET, your engine will operate normally in all the direction
states of forward, neutral and reverse.
HORN OPERATION
Your MTH E-33 Rectifier ProtoSound-equipped engine is equipped with a
digital recording of a E-33 Rectifier Whistle. The whistle sound can be
activated anytime the engine is in forward or reverse by pressing the whistle
button on your transformer. The whistle will continue to blow as long as
the whistle button is depressed. The whistle will not function in RESET
and must be configured through a RESET option to allow the whistle to
work when the engine is in neutral. See page 20 for information on whistle
programming in the
Using RESET To Program Proto-Sound®
section of
this manual.
BELL OPERATION
Your MTH E-33 Rectifier Proto-Sound® engine is equipped with a digital
recording of an actual bell. Unlike previous versions of Proto-Sound®, the
bell can be turned on or off with any separate bell button, like the Lionel®
Railsounds® No. 5906 Bell Button, by simply pushing the button. If you
don’t have a separate bell button, the bell can be controlled through your
transformer’s whistle button whenever the engine is in NEUTRAL. The
