Ground Speed Override Switch
I
f your ARC system includes an optional MID-
TECH® Boom Control Switch Box, the Ground
Speed Override (GSO) switch is already installed.
An optional, externally mounted, GSO switch can be
used to temporarily operate the sprayer using a pre-
selected, "GSO” , minimum speed rather than the
actual vehicle ground speed. The override feature is
used to reach the application rate quickly when
starting the vehicle from a complete stop or to
maintain an adequate spray pattern when the vehicle
is moving at very low ground speeds. It can also be
used to allow the operator to flush or empty the tank
from the cab, with the vehicle stopped.
The Control Console operates normally as long as the
GSO switch condition is open (OFF). Whenever the
switch is closed (ON) and the actual ground speed is
less than the "GSO Speed", the Control Console
automatically uses the "GSO Speed" value to control
application rate. As soon as the switch reverts to its
normally open (OFF) condition, or the actual ground
speed increases above the preset "GSO Speed", the
Control Console will adjust the application rate based
on the actual ground speed.
CAUTION: Controlling application rates based on a
"GSO Speed" is not as accurate as using the actual
ground speed. When Ground Speed Override is being
used and the true ground speed is less than the
"Ground Speed Override” speed, the console sounds
an alarm and the display flashes a "Too Slow"
message to warn the operator of possible mis-
application.

Fig. B-6, in Appendix B,
shows a “Boom Control
Switch Box” which incorpo-
rates the Implement Status
Switch and the GSO function
into one switch. The “OFF”
position provides a Status
Switch “OFF” condition,
“AUTO” furnishes Status
Switch ON, and “GSO”
activates the GSO function.
Other methods of controlling
these functions are also
available. This switchbox also
includes an individual ON/
OFF switch for each boom
section.
