Component Overview and Compatibility

The following component configurations are compatible with the GreenStar Rate Controller. See Main Harness (37-Pin Connector) Table at the end of the manual for additional pin out information.

Section Valves

• Section Valves with 3 wire SPST (Single Pole Single Throw)

  A 3-Wire valve is considered a valve with a solenoid-like operation. There is one signal wire controlling operation of the valve. When the signal wire is high (12 V), the valve is opened. When the signal wire is low (0 V), the valve closes. This can sometimes be referred to as a single pole single throw (SPST) valve. There may be configurations where a valve with this operation only has two wires, a signal wire and a ground wire.

• Section valves with 2-wire DPDT (Double Pole Double Throw). Not Compatible on NH3 systems.

  A 2-Wire valve is considered a valve with reversing capabilities. This valve needs two outputs to control its operation. When the (+) signal wire is high (12 V) and the (-) signal wire is low (0 V), the valve opens. Likewise, when the (-) signal wire is high (12 V) and the (+) signal wire is low (0 V), the valve closes. When both signal wires are low (0 V), the valve does not move. This type of valve can sometimes be referred to as a double pole double throw (DPDT) valve.

• Section Valves must require less than 2.5 amps of current

Section Valve Supplemental Information

IMPORTANT: Valve power and valve ground pins are not reverse-voltage protected. Precautions should be taken to prevent them from being connected backwards or the GreenStar Rate Controller may be damaged.

3 Wire SPST Section Valves

• Valve power and valve ground must be used for all section valves. If valve power and valve ground are not connected, section valves will not open or close.
• Section valves must be evenly split among available valve power and valve ground pins to disperse electrical load evenly through those terminals.

Raven Sidekick™ Pro Direct Injection Pump Compatibility

GreenStar Rate Controller is compatible with the Raven Sidekick Pro direct injection pump for applying product using the following implements:

• Sprayers
• Liquid fertilizer tools
• NH3 applicators

Raven Sidekick Pro injects varying amounts of product into the main solution line of the implement. This eliminates the need to mix chemicals in the main tank. GreenStar Rate Controller can be configured with up to three Raven Sidekick Pro direct injection pumps.

IMPORTANT: If multiple GreenStar Rate Controllers are being used, only one GreenStar Rate Controller should be configured to communicate with all direct injection pumps on the system.
