3.5.3 CHANGING THE PERCENT RATE OF CHANNELS 1,2,3 AND L SIMULTANEOUSLY
TASC allows the operator to change the application rate of channels 1,2,3 and L by a percentage amount
using the INC/DEC switch. The change will not affect channel C. The percentage change will affect either
the normal or alternate rate of each channel, depending on which has been chosen with the rate selector
switch.
The operator selects the L & CHEMICALS, APPL. RATE position while in the OPERATE mode. The
console displays the actual application rates while applying (or the desired rates with the vehicle at rest).
Toggling the INC/DEC switch will change rates up or down by the percentage set in the % RATE position.
The display will momentarily show the new percentage target rate before displaying the actual discharge
rates. The percent rate change is canceled by switching out of the L & CHEMICALS, APPL. RATE
function.
CAUTION: Operating with a changed chemicals application rate is not a normal condition. TASC will
continue to remind the operator that he has selected a changed rate. TASC will beep an alarm and
display a flashing % RATE message on the display.
3.5.4 CHANGING THE PERCENT RATE OF ALL CHANNELS SIMULTANEOUSLY
TASC allows the operator to change the application rate of all channels by a percentage amount using
the INC/DEC switch. The percentage change will affect either the normal or alternate rate of each channel,
depending on which has been chosen with the rate selector switch.
The operator selects the % RATE position while in the OPERATE mode. The console displays 100.
Toggling the INC/DEC switch will change all rates up or down by the percentage set in the % RATE
position. The display will show the new percentage target. The percent rate change is canceled by
switching out of the % RATE function.
CAUTION: Operating with a changed application rate is not a normal condition. TASC will continue
to remind the operator that he has selected a changed rate. TASC will beep an alarm and display
a flashing % RATE message on the display.
3.6 MANUAL OVERRIDE OF FLOW CONTROLS
Sometimes it is necessary to manually override the flow control valves. This feature is useful for stationary
unloading of the vehicle using the spreader conveyor, or for priming of the liquid pump when first starting
the sprayer. TASC allows the control valves on channels C and L to be overridden easily.
3.6.1 OVERRIDE CHANNEL C CONTROL
Select the CARRIER, Appl. Rate position on the display selector switch while in the SET-UP mode. Switch
the channel C rate switch to the center ON position. Use the DEC switch to zero the channel C application
rate. Switch the mode selector to OPERATE. The display will show "Flow Contl OFF Auto". Channel
C flow control valve will now respond to toggling of the INC/DEC switch. INC opens the valve and DEC
closes the valve. The switch must be held for a few seconds for the valve to open or close all the way.
To view the actual application rate while in the manual override mode, switch the associated rate switch
to the alternate rate position. There must also be some ground speed.
To escape from this condition, enter an application rate for channel C. TASC will then perform normally.
