3.1.6 CHECK THE VEHICLE
Make sure the hydraulics (or liquid) pumps are engaged and operating normally.
3.1.7 START APPLYING
Drive the vehicle toward the application area and turn booms ON to start applying. TASC is
automatically controlling application of the selected channels. Area and amounts applied will begin
to accumulate. The console will display actual application rates.
3.1.8 STOP APPLYING
Reaching the end of the field, turn the booms OFF. The application will stop. After the vehicle has
turned, switch the booms back ON to control application.
3.2 GROUND SPEED OVERRIDE (GSO)
An optional ground speed override switch can be used to operate the sprayer using the GSO speed.
Ground speed override is used to bring the applicator channels on line quickly when starting from a dead
stop. Ground speed override will also ensure a minimum acceptable pattern when the vehicle is
maneuvering at very low ground speeds. GSO can also be used to flush the applicator channels from the
cab, with the vehicle stopped.
TASC operates normally when the GSO switch is in the OFF (open) condition. When the GSO switch is
ON (closed), and the actual ground speed is less than the GSO speed, TASC selects the GSO speed to
adjust the conveyor and chemical flow rates. When the actual ground speed increases above the preset
GSO speed, TASC will control flow rates using the actual ground speed. See the following table for a better
example of GSO operation.
CAUTION: Controlling application rates using GSO is not as accurate as using actual ground speed.
When GSO is active and the actual ground speed is less than the GSO speed, the console will sound
an alarm and the display will flash a Too Slow message to warn the operator about over application.
3.3 CHANGING ACTIVE BOOM SECTIONS
The active boom sections can be changed at any time by turning the boom switches ON or OFF. TASC
will automatically adjust application flow rates to account for the change in width. Area accumulators and
total applied accumulators also correct automatically for the change in width. When all boom sections are
turned OFF, application stops.
