A - Pressure Control Knob

Activation buttons 1, 2, and 3 are located on multi-function lever. When engaged, system float pressure will automatically adjust to the target pressure stored with the associated activation button. Float pressure can be adjusted with pressure control knob (A). Float pressure cannot be adjusted below pre-charge pressure.

When running header height control, buttons 1, 2, and 3 give different float priorities between feeder house and platform. Once an activation button is pressed, the corresponding system will begin adjusting. Once selected system has reached a stable level, other systems will be given priority accordingly.

NOTE: The actual activated mode is dependent upon the enabled modes and the setpoint activation button pressed as outlined.

Activation occurs on button press transitions.
