3.0. OPERATION
Under normal operating conditions, TASC is automatic. It performs precisely, according to the information and direc-
tions it receives from the operator. It is important to verify that TASC has the proper instructions before beginning
spraying operations each day.
3.1. NORMAL START UP AND OPERATION
A. CONSTANTS: With all boom switches in the OFF position, verify that the proper constants are still entered in the
console. Refer to section 2.0. of this manual to review the procedure for entering these constants. It is a good idea to
write the constants down in a convenient location.
B. APPLICATION RATES: With all boom switches in the OFF position and the Mode Selector switch in the SET-UP
position, review the standard and alternate application rates for each injection pump, and the carrier application rate.
Use the procedure outlined in Section 2.3 of this manual to select and change the rates as required.
C. ACCUMULATED AREA: If desired, the accumulated acres can be reset to zero by selecting AREA and holding the
INC/DEC switch down until the display resets to zero. NOTE: There are two Area Accumulators, one in the OPER-
ATE Mode and one in the SET-UP Mode. These can be zeroed independently to keep track of two separate areas.
D. ACCUMULATED VOLUMES: If desired, the accumulated volumes for the carrier, and for each chemical pump,
can be reset to zero by selecting CARRIER, TOTAL APPLIED or CHEMICALS, CHEM. APPLIED while in the
in the OPERATE Mode and using the INC/DEC switch to reset.
E. Now, TASC is ready to begin spraying. Set the Mode Selector Switch to the OPERATE position. If a TASC-6300 or
6600 is being used, select the desired injection pumps by turning those injection pump switches to ON or Alt. Rate.
Select an appropriate display using the Display Selector, AREA for example.
F. Start the carrier pump and pressurize the sprayer.
G. When you reach the starting point of the first swath turn the desired boom switches ON. TASC automatically controls
both carrier and chemical application. If an area or volume accumulator is selected on the Display Selector, the
accumulator begins to register.
H. Upon reaching the end of the swath, turn the boom switches, or the Master Switch, to the OFF position to tempo-
rarily stop spraying. All injection pumps and accumulators will stop. When the vehicle has been turned and is ready
to start spraying on the next swath, turn the booms ON and the sprayer, injection pumps and accumulators start again.
3.2. CHANGING ACTIVE BOOM SECTIONS
The active boom sections can be changed at any time by turning the appropriate boom switches ON or OFF. TASC
automatically adjusts the carrier flow rate and the injection rate of each pump as individual boom sections are activated
or deactivated. When all the boom section switches, or the Master Switch, are OFF, the injection pumps are stopped
also. This allows the operator to select active boom sections "ON THE GO”, while depending on TASC to apply the
proper chemical rates on the area actually being sprayed.
3.3. SELECTING DIFFERENT CHEMICAL COMBINATIONS
The TASC-6300 or 6600 allows the operator to select different chemical combinations while spraying. This is done by
activating or deactivating the appropriate injection pumps.
Switching individual injection pumps ON cause the TASC-6300 or 6600 to activate those particular pumps at the
predetermined application rates you have selected. Switching an injection pump switch to the OFF position, positively
stops that particular injection pump. The TASC-6300 will control up to three individual injection pumps, while the
TASC-6600 will control up to six pumps.
