2.8 BOOM CONTROL SWITCHES
Externally mounted boom control switches are necessary for the proper operation of TASC. MIDWEST
TECHNOLOGIES can provide several optional configurations for these switches to meet differing needs.
The console must receive 12 VDC on the boom status line whenever a boom is turned ON.
A boom master switch is a good feature. It should be used to turn on or off all selected booms simulta-
neously.
2.9 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 will bring the applicator on line quickly when starting from a dead
stop. GSO can also be used to maintain a minimum application rate when maneuvering the vehicle at
very low ground speeds. Finally, GSO can be used to empty the applicator from the cab while the vehicle
is stopped.
TASC operates normally, so long as the GSO switch is turned OFF. When the GSO switch is closed
(ON), and the actual ground speed is less then the minimum speed preset in the console, TASC auto-
matically selects the minimum speed value to control application rates. As soon as the switch is turned
OFF, or the actual ground speed increases above the minimum speed, TASC will control application rates
based on the actual ground speed.
If your GSO Switch is labeled "OFF / AUTO / GSO", the functions will be as follows. GSO will operate the
same as GSO ON above. AUTO will operate like GSO OFF above. The OFF position will operate the
same as turning the STATUS switch off. (See paragraph 2.10 below)
CAUTION: controlling application rates based on minimum speed is not as accurate as using the
actual ground speed. When GSO is being used and the actual ground speed is less than the mini-
mum speed, the console will sound a warning beep and flash a "Too Slow" message to warn the
operator of possible over application.
