CONSOLE PROGRAMMING AND CALIBRATION
10. Enter the width in inches [cm] of BOOM 2 in the BOOM CAL 2 field.
NOTE: If there is only one boom, enter “0” for the width of BOOM 2.
11. Enter the width in inches [cm] of BOOM 3 in the BOOM CAL 3 field.
NOTE: If there is only one or two booms, enter a “0” for the width of BOOM 3.
12. Press the METER CAL button and enter the meter cal value stamped on the flow meter’s identification tag.
13. Press the VALVE CAL button and enter the calibration number that corresponds with the control valve being
used.
14. Press the RATE 1 CAL button and enter the Rate 1 value that was previously calculated.
15. Press the RATE 2 CAL button and enter the Rate 2 value that was previously calculated.
IMPORTANT: The Rate 2 value should not vary by more than 20% from the Rate 1 value, or the spray pattern may suffer.
If a second rate is not being used, enter the same value that was entered for the Rate 1 Cal.
The initial console programming is now complete, and the flashing “CAL” in the console’s display should turn off. If
it does not, repeat the procedure starting from step 7 above.
REFINING THE SPEED CAL VALUE - RAVEN RADAR ONLY
The initial Speed Cal value when using Raven radar is 598 [152]. However, after initial console programming, it may
be necessary to refine this number to improve the system’s performance. Complete the following steps to refine
the speed cal value:
1. Turn the POWER switch ON.
2. Turn all boom switches OFF.
3. Press the DISTANCE button on the SCS 440 console.
4. Enter 0 as the value.
5. Drive 1 mile [1 km].
NOTE: Do not use the vehicle’s odometer to determine the distance. Use highway markers or section lines to
measure the distance traveled. To achieve the most accurate calibration, accelerate and decelerate
slowly using typical application speeds.
6. Press the DISTANCE button. The value should be approximately 5280 [1000]. If the value is between 5260 -
5300 [990 - 1010], the speed cal value for the machine is 598 [152]. If the value is any other value, use the
following formula to recalculate the speed cal value.
FOR EXAMPLE: Assume that the DISTANCE value is actually displayed as 5000 [980].
IMPORTANT: The new Speed Cal value must be rounded to the nearest whole number.
Old SPEED CAL X 5280 = Adjusted Speed Cal
DISTANCE VALUE
598 X 5280 = 631.48 (English)
5000
[152] x [1000] = 155 [metric]
[980]
