Tools Menu

Valve

Touch the Valve button to access the Valve Calibration screen.

Valve Type

Select the type of control valve used to control the selected product during a job.

Note: If ‘PWM’ or ‘PWM Close’ is selected as the valve type, a button labeled ‘Modify PWM Settings’ will

appear on this screen.

Valve Cal

The valve cal value helps the field computer adjust the valve control response for slight differences between

control valves and is required for product control. Raven Industries recommends the following valve calibration

values for initial system setup.

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. See Appendix A, Calculating the

Calibration Values, for instructions on refining the valve cal value.

Valve Cal 2

This value can fine tune control valve response and help control application rate oscillations when the console

is programmed in PWM mode.

When a fast close valve is selected, valve cal 2 is utilized to enable a high resolution rate control for lower

application rates. Enter a non-zero value for the time, in milliseconds, which the valve will be fully opened

before switching into high resolution control. For example, a value of 200 will give the valve a 200 millisecond

“burst” at a full 12V to open the fast valve from the closed position before resuming product rate control. A zero

value will disable this feature.
