ISOBUS PRODUCT CONTROL NODE CALIBRATION

The valve cal value sets the responsive characteristics of the control valve and is required for product control. The

recommended value is automatically entered when the valve type is selected. For more information about

adjusting the valve cal, see the Valve Cal section on page 62.

VALVE CAL 2

NOTE: If the dual loop control feature is enabled, the valve cal 2 value will be replaced by the Sgain value.

The valve cal 2 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, the valve cal 2 value is utilized to enable a high resolution rate control for

lowering 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 fully 12 V to open the fast valve from the closed position before resuming product rate control. A zero

value will disable this feature.

RESET VALVE CAL BUTTON

Select “Reset Valve Cal” button to reset the recommended value for the selected valve type.

VALVE ADVANCE

This feature allows the operator to set the amount of time (in seconds) which the control valve will open after

boom sections are toggled off while in automatic rate control mode. A value of 1-9 means an advance of 1-9

seconds respectively. A value of 0 means no advance. This setting may be used in conjunction with the valve delay

for low rate applications to build up pressure when the master switch is toggled on. For best results, approach the

headlands at consistent speeds while turning boom sections off.

NOTE: The valve advance value is only accessible if a standard, fast or fast close valve is selected and if the

assigned product control node has software version 2.2.05 or higher.

FLOW RATE DISPLAY

The flow rate display on the Valve Calibration screen displays the current product flow rate as a reference.
