Product Densities
The density of dry or granular products is required to properly calibrate the application system for the weight of
1 cubic foot [1 cubic meter] of product being applied by each product node or control channel configured for a
dry or granular product.
Note: To maintain accuracy of the Viper Pro control system, the density value should be adjusted as the
measured density of the granular product changes throughout the application.
1. Touch within the Product Control area at the bottom of the main screen.
2. Make sure that Node 1 is selected on the CAN Controller Status screen and touch within the second data
display area, or the Product Control Settings area, on the CAN Controller Status screen.
3. Touch the density value displayed on the screen and use the on-screen keypad to enter the measured
density of the product to be applied.
4. Repeat the above process for any remaining nodes or product control channels as necessary.
5. Touch OK to save the entered value or proceed to the Valve Cal(s) section on page 44 to continue with the
initial set up process.
Valve Cal(s)
Note:
The Viper Pro automatically enters the recommended valve cal value for the valve type selected
during the procedure in the Application and Control Valve Type(s) section on page 40.
If the dual loop control feature is enabled, the valve cal and valve cal 2 values will be replaced by
the flow cal and pr Sgain (pressure system gain) values. See the Node Feature Settings Screen
(Page 2) section on page 136 for information on enabling the dual loop control feature. Refer to the
Dual Loop Control Cals section on page 45 for more information on setting the flow cal and pr
Sgain values.
1. Touch within the Product Control area at the bottom of the main screen.
2. Make sure that Node 1 is selected on the CAN Controller Status screen and touch within the second data
display area, or the Product Control Settings area, on the CAN Controller Status screen.
3. Touch the Next button to view additional settings for the selected product node or control channel.
4. Touch the displayed valve cal value and use the keypad to enter the calibration value for the installed
control valve.
Note: Raven recommends the following initial valve cal values:
These values are good starting points and will generally yield adequate results, however, the valve
cal should be refined for the individual control valves installed on the specific machine. Refer to
Appendix B, Calculating the Calibration Values, for more information on calculating the valve cal.
5. Repeat the above process for any remaining nodes or product control channels as necessary.
6. Touch OK to save the entered value or proceed to the optional Valve Cal 2 (Optional) section if applicable to
continue with the initial set up process.

Fast or Fast Close Valve (C-F or C-FC) 743
PWM or PWM Close Valve (C-P or C-PC) 43
