3.6. GROUND SPEED OVERRIDE
An optional Ground Speed Override Switch can be used to temporarily operate the sprayer using the "GSO Speed"
instead of the actual speed registered by the Ground Speed Sensor, (See Sec. 2.10). The override feature is used to bring
the sprayer on line quickly when starting from a dead stop or to maintain an adequate spray pattern when the vehicle is
maneuvering at very low ground speeds. It can also be used to allow the operator to flush the sprayer from the cab with
the vehicle stopped.
The Control Console operates normally when the Ground Speed Override Switch is in the OFF (open) condition.
When the Override Switch is ON (closed) and the actual ground speed is less than the "GSO Speed", the Control
Console automatically uses the "GSO Speed" value to adjust both Carrier and Injected Chemical flow rates. If the actual
ground speed increases above the preset "GSO Speed", the Control Console reverts to controlling flow rates based on
the actual ground speed.
Examples:
GSO Switch "GSO Speed" Actual Ground Speed Control Speed
"OFF" 5 mph 6 mph 6 mph
"OFF" 5 mph 4 mph 4 mph
"ON" 5 mph 6 mph 6 mph
"ON" 5 mph 4 mph 5 mph
CAUTION: When traveling at a speed slower than the GSO speed setting, this feature will cause the Product to be
applied at a Rate consistent with the GSO speed, rather than the true ground speed, possibly resulting in serious
over application. When Ground Speed Override is being used, and the true ground speed is less than the pre-
selected “GSO” Speed, the console will sound an alarm and the display will flash a “Too Slow” message to warn
the operator of possible over application.
3.7. PRIMING THE MAIN PUMP AND BOOM
Use the following procedure to “PRIME” the main pump and boom lines prior to spraying (VERSION 2.8 and higher).
A. Set the console switches to the following positions:
Power ON
Mode Selector OPERATE
Display Selector PRIME
Pump Switches OFF
B. A series of five dashes (- - - - -) will appear on the display.
C. Hold the INC/DEC switch up for about three seconds. The main control valve opens and remains in this
position. While operating in this mode, there is no accumulation of area, distance or carrier.
D. The main pump can be run, with the booms open, to prime the sprayer. TASC does not try to shut down the
sprayer because it doesn't see any flow. The control valve remains "OPEN".
E. Select any normal position of the Display Selector Switch and TASC is ready to begin normal spraying.
