booms are turned OFF. HOLD is useful in maintaining pressure to the boom shut-off valves on a liquid control
channel.
To check or change the valve response, use the following procedure:
A. Set the console switches as shown:
Power ON
Mode selector SET-UP
Display selector SCAN
Booms OFF
Product L, C, 1, 2, or 3 ON (CENTER) (one at a time)
The display will read HOLD or CLOSE. The response can be changed using the INC switch. (Hold the INC
switch up until the display changes. The response shown on the display when the switch is released is the
selected response for that channel.) There is no selectable response when the channel is in peristaltic or non-
peristaltic mode.
B. If no channel is selected or, if more than one channel is selected, the display will read Err.
2.7 SETTING THE GROUND SPEED OVERRIDE SPEED (GSO)
The GSO function generates an operator selectable speed signal which TASC will use whenever the GSO switch is
turned on and actual ground speed is less than the selected setting.
A. Use the following switch settings to enter the desired GSO speed.
Power ON
Mode selector SET-UP
Display selector SPEED
B. Use the INC/DEC switch to set the desired speed.
C. The GSO speed will be used by TASC whenever the GSO switch is ON (closed) and the actual ground
speed is less than the GSO speed selected.
NOTE: If you do not have a GSO switch, the only way to turn GSO off is to set the GSO speed to zero.
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.
2.8 SETTING THE TEST SPEED VALUE
The Test Speed function generates an operator selectable speed signal which TASC will use whenever the Display
Selector Switch is set to the Test Speed position.
A. Use the following switch settings to enter the desired test speed.
Power ON
Mode selector SET-UP or OPERATE
Display selector TEST SPEED
B. Use the INC/DEC switch to set the desired speed.
