GROUND SPEED CONFIGURATION (F7)
1. From the keyboard, select Function key F7 to display the Ground
Speed screen, refer to (Figure 40).
2. Press 2 to edit parameters on the screen.
– MAX SPEED - Indicates the maximum speed the operator can
drive in the AUTO mode before a "MAX SPEED EXCEEDED"
warning appears and the alarm sounds. The value entered is
arbitrary based upon knowledge of the highest speed giving
acceptable system performance. If a zero (0) is entered, the
function is disabled.
– MANUAL ON - If the ground speed sensor becomes damaged, an
internally-generated ground speed signal can be substituted
temporarily to continue operation. The artificial ground speed signal
activates by entering Y (Yes). This signal is also useful for testing,
troubleshooting, or calibrating the vehicle while stationary.
– MANUAL DRIVER - Y (Yes) enables the operator to activate the
manual speed mode by adding Manual Speed selection to the
bottom of the Material/Manual Speed Select screen. N (No)
removes the choice.
– MANUAL SPEED - Represents the ground speed in miles per hour
(MPH) to be simulated with an artificial, internally-generated signal.
The operator must attempt to maintain vehicle speed near this
Manual Speed value to ensure materials are spread near the target
APR.
– START UP - Represents the speed the system begins when ground
speed sensor pulses start. Until this threshold is crossed, the start
up ground speed signal is used.
– SHUT OFF SPD - Shut-off speed is the minimum ground speed
allowed before the system stops operation. It is recommended that
shut-off speed be set at 0.0 unless speed appears from a
mechanical sensor.
– 2 AXLES - If the vehicle is equipped with a two-speed axle, enter Y
(Yes). Two constants will appear at the bottom of the screen.
– CONSTANT (Constant 1 and Constant 2) - Defines the number of
pulses received from the ground speed sensor per mile of travel. If
known, this constant can be keyboard entered. If unknown, the
value automatically calculates during ground speed calibration.
Those vehicles equipped with a two-speed axle require two
constants, Constant 1 and Constant 2. Depending upon axle-shifter
polarity, Constant 1 may be either the Lo-speed axle or the
Hi-speed axle.
