6.4 APPLICATION RATE SENSOR FAILURE (GRANULAR APPLICATION)
The TASC Spreader System, suffering a rate sensor failure, can be operated in a manner similar to the previously described
sprayer failure (section 6.3).
NOTE: If you are operating under GPS, first return the console to Local Control as described in the note in section 6.2.
A. Turn the Conveyor Switch OFF, so that no boom lights are lit, and stop the vehicle. Disconnect the rate sensor from
the flow control harness (3 pin connector).
B. Set the application rate to 0.0 (see sect. 2.4) and return the Mode Selector to OPERATE. The Hydraulic Flow Control
Valve will now respond only to manually activated INC/DEC commands from the Control Console.
C. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired
swath, turn on the Conveyor Switch and the spreader will start spreading. At this point, the operator is enjoying some
monitoring functions of the TASC, but has no automatic control of the hydraulic flow control valve. NOTE: On some
systems, the hydraulic control valve is used to turn the spreader on and off. If this is the case, it will be necessary to hold
the INC/DEC switch up to start spreading, and down, to stop spreading.
NOTE: The display selector must be turned to the APPLICATION RATE position in order for the INC/DEC switch to
control the valve.
D. Monitor SPEED. Adjust the ground speed to reach the target rate desired. SPEED will read correctly and AREAS will
accumulate normally. The Application Rate will not be displayed.
MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE ONLY AS AN EMERGENCY, TEMPO-
RARY PROCEDURE. THE PROBLEM WITH THE RATE SENSOR SHOULD BE RESOLVED AS SOON AS
PRACTICAL SO THAT FULL CONTROL OF THE SPREADER CAN AGAIN BE ENJOYED.
