application rate at the target speed. Adjust the pump bypass valve (if one is provided) or manually turn the valve stem to
generate the desired pressure downstream of the main carrier pump. Turn all boom sections OFF.
D. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired
swath, turn on the appropriate boom switches and the sprayer will start to spray. At this point, the operator is enjoying
some monitoring functions of the ARC, but has no positive control of the flow control valve.
E. Monitor APPLICATION RATE. Actual application rate will be displayed. Adjust the ground speed to reach the
application rate desired.
F. The console cannot automatically adjust for changes in boom widths. If booms are shut off, pressure must be reset.
Volumes and areas will accumulate normally. Speed will read correctly.
G. MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE AS AN EMERGENCY, TEMPORARY
PROCEDURE ONLY. THE PROBLEM WITH THE FLOW CONTROL VALVE SHOULD BE RESOLVED AS
SOON AS PRACTICAL SO THAT FULL CONTROL OF THE SPRAYER CAN AGAIN BE ENJOYED.
6.3. FLOWMETER FAILURE (LIQUID APPLICATOR)
The procedure is very similar to operating without the flow control valve, except , in this instance, the flow control valve is cycled
using a manual override procedure.
A. Shut all boom sections OFF and stop the vehicle.
B. With the control console Power ON, set the Mode Selector switch to OPERATE and the Display Selector to APPLI-
CATION RATE. Using the INC/DEC switch, set the display to 0.0. Now, hold the DEC switch for another 5 seconds
until the display indicates "Flow Contl OFF Auto".
C. The Flow Control valve will now respond only to manually activated INC/DEC commands from the control console.
The control system will remain in this configuration until the control console power has been switched OFF. Switching
control console power back ON will clear the manual control option.
D. Turn ON the normal boom sections and allow spray. Use a nozzle chart to determine the boom pressure that will give
the desired application rate at the target speed. Adjust the boom pressure using the INC/DEC switch on the control
console. INC will open the Flow Control valve and DEC will close the valve. Once the desired pressure is attained,
turn all boom sections OFF.
E. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired
swath, turn on the appropriate boom switches and the sprayer will start to spray. At this point, the operator is enjoying
some monitoring functions of the ARC, but has no automatic control of the flow control valve.
F. Monitor SPEED. Adjust the ground speed to reach the target speed desired.
G. The console cannot automatically adjust for changes in boom widths. If booms are shut off, pressure must be reset
using the INC/DEC switch. Areas will accumulate normally. Speed will read correctly.
H. MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE AS AN EMERGENCY, TEMPORARY
PROCEDURE ONLY. THE PROBLEM WITH THE FLOWMETER SHOULD BE RESOLVED AS SOON AS
PRACTICAL SO THAT FULL CONTROL OF THE SPRAYER CAN AGAIN BE ENJOYED.
