Set Up NH3+ Boost Pump

It is recommended to select Duty Cycle as a data field to display when the boost pump is present.

(For more information on changing display settings, reference Adjust Settings.)

The Raven AccuFlow HP™ Plus is controlled based on flow. The John Deere Rate Controller 2000 is only able to control one fast valve when utilizing an NH3 AccuFlow HP™ Plus configuration. Use a PWM in conjunction with a fast control valve to control the AccuFlow HP™ Plus boost pump.

NH3 AccuFlow HP™ Plus configuration requires two pressure sensors:

• Sensor 1 on the gauge tree.
• Sensor 2 on the pump inlet.

Recommend starting settings:

• Coil Frequency: 122
• High limit: 85
• Low limit: 20
• Response Rate: 70
• Control Deadband: 3
