F. TASC displays the indicated amount discharged. Measure the actual amount discharged and
correct the calibration number using the following formula:
G. Set the mode selector switch to SET-UP and enter the corrected calibration number using the
INC/DEC switch.
(Remember, if the channel is set for split drive, the booms must be ON to view
the calibration number, turn the booms OFF before proceeding further.) Return to OPERATE and
the display should indicate the actual measured amount collected. That channel is calibrated.
Calibrate each granular bin channel independently using this procedure.
6.11 SETTING THE HOLD OR CLOSE RESPONSE OF CHANNEL C AND L CONTROL VALVES
The operator has the option of selecting the response of the control valve to the booms OFF condition.
When the valve response CLOSE is selected, TASC will close the control valve when the booms are shut
OFF. When the HOLD response is selected, TASC will hold the valve in its current position when the
booms are turned OFF. HOLD is useful in maintaining pressure to the boom shut-off valves on a liquid
control channel.
To check or change the valve response, use the following procedure:
A. Set the console switches as shown:
Power ON
Mode selector SET-UP
Display selector SCAN
Booms OFF
Channel L or C ON
The display will read HOLD or CLOSE. The response can be changed using the INC
switch. (Hold the INC switch up until the display changes. The reading left on the display
after the switch is released is the selected response for that channel.)
B. If neither the L or C channels are selected or, if both the L and C channels are selected, the
display will read Err.
(MEASURED AMOUNT ÷ INDICATED AMOUNT) X CALIBRATION NUMBER = NEW
CALIBRATION NUMBER. If the amount read from the console is greater than the
amount actually measured, the calibration number will decrease.
