Controller Settings: Direct Injection Pump Calibration; Pump Calibration Setting; Rate Response Warning; Flow Monitor Warning - Ag Leader EDGE User Manual

• 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 steering 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
Calibration number representing the pulses that equal one revolution of the rate control metering system.
• Max Conveyor Speed
Setting determines the maximum RPM of the conveyor that controls product distribution to the application
point. This setting is used when controlling a spinner spreader applicator.

Controller Settings: Direct Injection Pump Calibration

Pump Calibration Setting

• Factory Calibration
The Factory Calibration Number is found on the tag of the Digital Pump Speed Sensor. This tag number
represents pulses per 10 fluid ounces. Divide the tag number by 10 and enter this number. Once entered,
this number should not be changed.
• Perform Calibration
Press the Perform Calibration button to begin the calibration procedure for the Direct Injection pump. The
pump will not run until this calibration has been performed.

Rate Response Warning

• Error Threshold
The user-defined percentage of actual rate error allowed before an alarm sounds.
• Error Delay
The number of seconds that an actual rate falls out of the error threshold before an alarm sounds.

Flow Monitor Warning

• Error Threshold
The percentage of perceived application error based on the discharge flow sensor.
