Chapter 530 SCS 660 & 660M Serial Interface for Granular Applications Installation & Service Manual8. Press ENTER. The message “CAL SELF TEST 00” will appear in the console’s display.9. Press the BOOM CAL button. The message “CAL BOOM 1 CAL” will appear in the console’s display.10. Enter the boom width that was previously calculated.11. Use the arrow keys to advance to the remaining booms and enter the data for each boom.Note: If a boom is not being used, enter 0 for the boom length.12. Press the SPEED CAL button and enter the appropriate speed cal value for the type of sensor being used.Note: The SPEED CAL value will have to be calibrated if Raven radar is not being used.13. Press the METER CAL button and enter the product density in pounds [gram/liter] as the Meter Cal value.14. Press and hold the METER CAL button for five seconds and enter the Spreader Constant value.15. Press the VALVE CAL button and enter the calibration number that corresponds with the control valve beingused.16. Press the RATE 1 CAL button and enter the Rate 1 value that was previously calculated.17. Press the RATE 2 CAL button and enter the Rate 2 value that was previously calculated.Note: 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 turnoff. If it does not, repeat the procedure starting from step 7 above.Refining the Speed Cal Value - Raven Radar OnlyThe initial Speed Cal value when using Raven radar is 598 [152]. However, after initial console programming, itmay be necessary to refine this number to improve the system’s performance. Complete the following steps torefine the speed cal value:1. Set the boom POWER switches to ON.2. Turn all other boom switches OFF.3. Press the DISTANCE button on the SCS 660 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 sectionlines to measure the distance traveled. To achieve the most accurate calibration, accelerate anddecelerate slowly.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 thefollowing formula to recalculate the speed cal value.For Example: Assume that the DISTANCE value is actually displayed as 5000 [980].Old SPEED CAL X 5280 = Adjusted Speed CalDISTANCE VALUE598 X 5280 = 631.48 (English)5000
