NYC Dreyfuss Operating Manual
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 17).
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 WHISTLE 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 WHISTLE 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 whistle doesn’t blow in NEUTRAL (unless you programmed it to do so
using Feature 25. See page 16 for details), only the bell rings or the coupler operates in
NEUTRAL. While it doesn’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.
