Program ProtoSounds™ on page 15). Once in Feature 18, press the transformer whistle
button and wait for ProtoSounds to sound a garbled bell sound.
REVERSE UNIT LOCK-OUT OPERATION
ProtoSound’s unique design eliminates the need for a lock-out switch on the locomotive by
allowing the customer to lock the engine into any directional state (forward, neutral or
reverse) from the transformer. This will allow users to run the engine on layouts equipped
with block signals or stop stations which would normally cycle the engine back into neutral.
The feature must be first turned on by accessing RESET Feature 40 (See page 18).
LOCKING THE ENGINE INTO FORWARD OR REVERSE
To lock the engine into Forward or Reverse, use the transformer throttle to enter Forward
or Reverse (whichever state you want to lock the engine into) and while the engine is
moving press the whistle button. WHILE THE HORN IS BLOWING TURN THE
THROTTLE OFF AND THEN LET GO OF THE WHISTLE BUTTON. After about one
second, you will hear a short horn blast. QUICKLY TURN THE THROTTLE BACK ON
AGAIN. Your engine is now locked into Forward or Reverse and it will remain so until you
unlock the engine, even if you wait a year to run your engine again.
UNLOCKING THE ENGINE
Unlocking the engine is a similar procedure. WHILE THE ENGINE IS MOVING, PRESS
THE WHISTLE BUTTON. WHILE THE HORN IS BLOWING, TURN THE THROTTLE
OFF AND THEN LET GO OF THE WHISTLE BUTTON. After three seconds without
power you will hear one chime of the RESET bell. TURN ON THE POWER AGAIN. Your
engine is now in RESET and will operate normally once you interrupt power and enter the
forward direction.
LOCKING THE ENGINE INTO NEUTRAL
To lock the engine into the NEUTRAL position, PUT THE ENGINE IN NEUTRAL AND
WITH THE THROTTLE STILL ON, PRESS THE WHISTLE BUTTON.
WHILE THE
WHISTLE BUTTON IS BEING PRESSED, TURN OFF THE THROTTLE AND LET GO OF
THE WHISTLE BUTTON. After about one second, you will hear a short blast of the horn.
QUICKLY TURN THE POWER BACK ON AGAIN.
Your engine is now locked into
NEUTRAL.
NOTE:
When locking the engine in the Forward or Reverse positions, the whistle button
will blow the horn. But when locking the engine into the NEUTRAL position, the whistle
button may turn on or off sounds of the bell, coupler arming or coupler firing depending on
the transformer throttle voltage settings prior to the user’s attempt to lock out the engine.
Remember, the horn doesn’t’t blow in NEUTRAL (unless you programmed it to do so using
Feature 25. See page 17 for details), only the bell rings or the coupler operates in
NEUTRAL. While it doesn’t’t make any difference on how the lockout function operates,
you may hear one of the three different NEUTRAL-activated sounds.
To unlock the engine from the NEUTRAL position, follow the process to unlock the engine
in the Forward or Reverse directions above.
