Locking an Engine into a Direction:
Proto-Sound-equipped engines have a feature that allows you easily to lock the
engine into the direction it is currently running. Before you can do this, the
locomotive’s lock-out feature must be enabled. Most later Proto-Sound-equipped
locomotives are programmed with the lock-out feature disabled to prevent
accidental lock-outs. Please see the operating instructions for your locomotive for
how to enable the lock-out feature.
1. While the transformer is applying voltage to the track, firmly press and release
the Program button. The Volts display will flash off, then read “52” and the Amps
display will flash off then read “PG.”
2. Depress the Direction Button and scroll to feature 50.
3. Firmly press and release the Bell button to start the Lock-Out Macro. At this
point, the Z-4000 will blow the locomotive horn or whistle while reducing the track
voltage to 0.0. Within two seconds of the track voltage dropping, your locomotive
will sound a short blast of its whistle or horn and track power will be restored. At
this point the locomotive will be locked into the direction it was traveling when you
activated the feature. Turning the transformer off and then on again should not
allow the engine to stop and change direction.
4.
Note: When locking an engine into Neutral, you must set track voltage below 10 volts. At
this voltage, activation of the Lock-Out Macro may cause the bell to begin ringing rather than
sounding the whistle/horn. This is normal.
