9.0 Locomotive Speed Control
To control the speed of a locomotive:
1. Select the loco address on either throttle
2. Turn the throttle knob clockwise to increase speed and counterclock-
wise to decrease speed
or
3. Use the Y +
& N-
Keys to increase and decrease speed.
The % of full speed will be displayed in the text line of the display on the L or
R side depending on which throttle is controlling the loco. The % of full speed
will also be displayed on the bar graph above the text area in the display.
If a loco address is part of a consist and is not the “TOP” (or controlling loco-
motive) and you try to change its speed the LCD screen will show “cn” in the
text area where % speed would normally appear. The “cn” lets you know that
the loco you have selected is part of a consist and that you cannot change the
speed or direction of this loco independently of the consist.
10.0 Stop
10.1 Setting A Loco to Zero Speed
Turn the Throttle Knob that the loco address is selected on counterclockwise
until the speed display shows 00 and the loco stops moving. This lets you slow
down your loco and stop it prototypically.
If you have set up deceleration for the loco and you move the throttle knob to
0% speed, your loco will slow down and come to a stop at the programmed
deceleration CV value. We strongly recommend that you run your locos with
the factory default of no deceleration until you are familiar with your system.
If the deceleration CV value you set for a particular loco is very large, this can
make it look like the loco is not stopping on command because the deceleration
CV value is causing the loco to take a long time to come to a stop.
10.2 Emergency Stop
DT400s have two ways of causing an emergency stop. When you use emergen-
cy stop, the deceleration rate programmed into the decoder will not have an
effect and the stop will be immediate.
Local Stop
Press the EMRG STOP Key
to stop the loco that is active in the
DT400’s display. To resume operation, use the throttle knob associ-
