V 3.10
NORMAL MODE, AUTOMATIC "PRESSURE" OPERATION
The TASC can be setup to control to a desired pressure. As boom sections of a balanced
sprayer are turned on and off, the control valve will open and close to maintain a flow rate that
will give a constant pressure. The control valve will adjust according to boom width only.
SPEED will not adjust flow rate. To enter this mode do the following:
MODE SELECTOR switch to carrier application rate. SETUP/OPERATE switch to
SETUP. Use INC/DEC switch to set rate to 0.0. Put SETUP/OPERATE switch back to
OPERATE. Console will read "
Flow
Contl
OFF Auto ".
Monitoring a pressure gauge, use the INC/DEC switch to set the desired pressure. You are
now set to operate at a predetermined pressure. Injection pumps will track boom
width changes
and speed changes
to keep chemical rate per acre constant. The console will display flow as
GAL/ACRE
at speeds
above
1 mph.
Below
1 mph the console will display flow as
GAL/MIN
.
NORMAL MODE, SPECIAL PURPOSE BOOM WIDTHS
For broadcast spraying operations on slopes, separate widths can be programmed into the 'B'
or 'C' widths on the TASC console. Select the "Normal" mode and 'B' Width or 'C' Width on the
Boom Switch Panel. Select the Width display function and the "SET-UP" mode on the TASC
console. Enter the desired width in inches.
Now, whenever boom width 'B' or 'C' is selected on the switch panel, the TASC console will
automatically adjust its flow rate for the programmed width, regardless of the position of the
individual boom valves
