E-33 Rectifier Operating Manual
QUICK START - BASIC OPERATION
The MTH E-33 Rectifier contains state-of-the art electronics with several
built-in automatic features for incredibly realistic operation. Despite these
advanced features, the E-33 Rectifier is easy to operate with most
compatible standard AC transformers (see the compatibility chart on page
31). The E-33 Rectifier locomotive is controlled by a Proto-Sound®
DCRU® electronic reverse unit. The reverse unit operates in the same
manner that all reverse units function by using forward, neutral and reverse
states that are entered each time the throttle is turned on and off or by using
the transformer direction switch (if so equipped).
The E-33 Rectifier locomotive is controlled by a Proto-Sound® DCRU®
electronic reverse unit. The reverse unit operates in the same manner that
all reverse units function by using forward, neutral and reverse states that
are entered each time the
throttle is turned on and off or
by using the transformer
direction switch (if so
equipped).
The reverse unit is designed
to ignore dirty track, dead
spots on switches or minor
short circuits without
disrupting the engine
operation, even at slow,
prototypical speeds. Once the
engine is placed on the track,
the throttle on the transformer can be
advanced. You will see that only the
engine’s lights come on and that only two
dings of the Proto-Sound® bell occur
followed by the blower sounds (on
Proto-Sound® equipped 3-rail models).
The engine does not run. This is known as the RESET state and is
explained in more detail beginning on Page 4. The Proto-Sound® DCRU®
will not power the motors until the throttle is turned OFF and then ON
again. At this point, the engine will now function just like any other
electronic or mechanical E-unit.
