1.9 GROUND SPEED OVERRIDE SWITCH
An optional ground speed override (GSO) switch can be used to temporarily operate the system using a pre-selected
minimum speed. GSO brings the applicator on line quickly when starting from a dead stop and can also be used to
maintain a minimum application rate when maneuvering the vehicle at very low ground speeds (Actual application
rate, based on actual ground speed, is displayed). Finally, GSO can be used to empty the applicator from the cab
while the vehicle is stopped (zero ground speed) (Display reads "- FLO").
TASC operates normally, when traveling above GSO speed or when the GSO switch is OFF. When the GSO switch
is closed (ON), and the actual ground speed is less then the minimum speed preset in the console, the console
automatically selects the GSO speed value to control application rates. As soon as the switch is turned OFF, or the
actual ground speed increases above the GSO speed, TASC controls application rates based on the actual ground
speed.

with Master Switch and Off/Auto/GSO Switch
If your GSO Switch is labeled "OFF / AUTO / GSO", then you must have the switch in AUTO (console controls to
ground speed only) or GSO position (console controls to GSO speed if ground speed is below GSO speed). The OFF
position operates the same as turning the STATUS switch off. (See paragraph 1.10 below)
CAUTION: When traveling at a speed slower than the GSO speed setting, this feature causes the product to
be applied at a rate consistent with the GSO speed, rather than the true ground speed. Caution must be
exercised when operating in this mode as serious over application can occur, if not used properly. When GSO
is being used, and the true ground speed is less than the pre-selected “GSO” speed, the console sounds an
alarm and the display flashes a “Too Slow” message to warn the operator of possible over application.
1.10 STATUS SWITCH
An externally mounted status switch can be used to turn TASC on and off. As long as this switch is ON (closed)
TASC operates normally. Whenever the switch is OFF (open), TASC turns off the applicator channels.
The intent of the status switch is to control TASC through the normal operation of the vehicle. The status switch may
sense the ON/OFF condition of the main applicator or it may sense an implement UP/DOWN condition. Use of the
status switch can ease the operator work load.
