Component Overview and Compatibility

Valve power and ground pins are not reverse-voltage protected. To prevent damaging the control unit, take precautions to prevent pins from being connected backwards.

The following component configurations are compatible with the John Deere Rate Controller 2000.

(Reference Main Harness [47-Pin Connector] Table in Specifications section for more information.)

Section Valves

• Section valves with 3-wire single pole single throw (SPST).

  For the rate control setup, a valve with a solenoid-like operation is considered a 3-wire valve. There is one signal wire controlling operation of the valve. When signal voltage is high (12 V), valve is opened. When signal voltage is low (0 V), valve closes. This is sometimes referred to as an SPST valve. There may be configurations where a valve with this operation only has two wires, a signal wire and a ground wire.

  • Use valve power and valve ground for all section valves. If valve power and valve ground are not connected, section valves do not open or close.
  • Split section valves evenly among available valve power and ground pins to disperse electrical load evenly through those terminals.

• Section valves with 2-wire double pole double throw (DPDT). Valve is not compatible on NH3 systems.

  For the rate control setup, a valve with reversing capabilities is considered a 2-wire valve. This valve needs two drivers to control its operation. When (+) signal voltage is high (12 V) and (-) signal voltage is low (0 V), valve opens. Likewise, when (-) signal voltage is high (12 V) and (+) signal voltage is low (0 V), valve closes. When both signal voltages are low (0 V), the valve does not move. This type of valve is sometimes referred to as a DPDT valve.

• Section valves that require less than 2.5 A.

Raven Sidekick Pro™ ICD (ISO Client Device) Compatibility

Raven Sidekick Pro™ ISO pumps are not compatible with John Deere Rate Controller 2000.

John Deere Rate Controller 2000 is only compatible with the Raven Sidekick Pro™ ICD direct injection system. Raven Sidekick Pro™ ICD injects varying amounts of product into the main solution line of the implement. This eliminates the need to mix chemicals in the main tank.

John Deere Rate Controller 2000 supports up to four Raven ICD direct injection pumps with a carrier. Total products must remain under five.

When the direct injection pump is detected in the CAN bus, the John Deere Rate Controller 2000 automatically populates the additional product in the profile.

GreenStar™ 3 2630 Display can control a maximum of five products, but only up to four products can be documented. John Deere 4640 Universal Display and 4600 CommandCenter™ can control and document five products.
