5. Return the Mode Select switch to the OPERATE position and check to see that the accumulated distance is set at zero.
If not, reset it to zero using the INC/DEC switch.
6. Start driving. Drive the vehicle at a speed of between five and ten miles per hour. Distance measurements will start to
accumulate in the display.
7. Stop the vehicle at the end marker. The display will show the accumulated distance. Compare this distance to the actual
measured distance, to determine how much of a correction is necessary. For example, if an accumulated distance of 396
Ft. is shown after driving over a 400 foot range, the error in the distance calibration is 1.0%.
8. Calculate the new Distance Calibration Number using the following formula:
(Measured distance/Accumulated distance) x Old DC# = New DC#
Example: (400 / 396) x 1000 = 1010, the New DC#
NOTE: The same procedure is used, regardless of the type of distance sensor .
RECORD THE DISTANCE CALIBRATION NUMBER HERE: ______________
2.8. SETTING THE "HOLD/CLOSE" RESPONSE OF THE FLOW CONTROL VALVE
The operator can select a "Hold" or "Close" response of the Flow Control valve to both the Status switch and to an "All Booms
OFF" condition. These responses are independent of each other, allowing the operator to select a "Hold" condition for one and
a "Close" for the other. Careful consideration should be given to both conditions and the response selected for your application.
2.8.1. STATUS SWITCH
When the "Hold" condition is selected, turning off the Status switch will hold the Flow Control valve in its current position. The
valve will not close even though the vehicle speed may drop to zero. Then, when the Status switch is turned on the Flow Control
valve is already open and product flow is instantaneous. This response assumes that some other device has stopped the product
flow.
When the "Close" condition is selected, turning off the Status switch will automatically cause the Flow Control valve to close.
This response would be preferred when it is necessary to use the Flow Control valve to stop the product flow.
To select the desired response:
A. Set the console switches to the following positions:
Power ON
Mode Selector OPERATE
Display Selector TOTAL APPLIED
Boom Switches OFF
B. Hold the INC switch up to display the current response selected.
C. Continuing to hold the INC switch up causes the display to cycle between "Hold" and "Close" at about three second
intervals. The last option appearing in the display when the INC switch is released will be the response selected.
2.8.2. ALL BOOMS "OFF"
When the "Hold" condition is selected, all booms OFF will hold the Flow Control valve in its current position. The valve will
not close even though the vehicle speed may drop to zero. Then, when the booms are selected ON again the Flow Control valve
is already open and product flow is instantaneous.
When the "Close" condition is selected, all booms OFF will automatically cause the Flow Control valve to close. This response
would be preferred when it is necessary to use the Flow Control valve to positively stop the product flow.
