Auxiliary Input Settings
• Master Switch
Switch that performs global master control of all rate control channels.
• F1 – F11
Settings determine the switch(s) that will operate the controlling channel specified from the configuration
setup. Single switches can be used to control multiple channels and swath sections.
Controller Settings
• Flow Meter Cal
Calibration value representing the number of pulses that equal one-gallon of product flow through the
controlling system.
• Control Valve Configuration
Setting specifies the type of control valve being used for the rate control functions of the controlling system.
• Response Threshold
Determines where the control channel switches between using Valve Response 1 and Valve Response 2
speed setting.
• Valve Response 1
Determines the speed of the servo valve when product control error exceeds the Response Threshold
setting. Valve Response 1 represents the fast speed of the servo valve.
• Valve Response 2
Determines the speed of the servo valve when product control error is less than the Response Threshold
setting. Valve Response 2 represents the slow speed of the servo valve.
• Allowable Error
Determines the percent of error that is allowed prior to the product control system making any flow rate
changes.
• Flow Control Delay
Setting for period of time from master switch on and the start of product application to the first flow control
correction. This setting can be used to eliminate unwanted correction of flow control at the start of each
pass. Typical setting values are zero for granular and 1 –2 seconds for liquid application control.
• Close Flow Control Valve When Rate Off
When selected the controlling system will shut down when there is either a zero rate in the field or entering
an already applied area. When unchecked the controlling system will stay in the last known state when the
sections are shut off.
• PWM Frequency
The frequency that the PWM control valve is pulsed at. Settings can be found from the manufacturer of the
valve. Typical settings range from 100-125 Hz.
• PWM Gain
Determines how aggressively the control valve responds when making rate change adjustments. The
higher the value the more aggressive the response is.
• Zero Flow Offset
Represents the maximum duty cycle that is sent to the control valve without producing any hydraulic flow
from the PWM valve. Using too high of a Zero Flow Offset value can cause the product control system to
not properly control low rates. See the PWM valve manufacturer information for recommended settings.
• Shaft Speed Cal
