CAUTION: Selecting the wrong valve type may result in valves opening unexpectedly. To avoid injury from exposure to chemicals, verify the correct valve is selected. Review control valve type before moving GreenStar Rate Controller between implements.

   Dual Valve System

   A - Control Valve Type Drop-Down Menu

   Select Control Valve type from the drop-down menu. See the following valve type descriptions.

   NOTE: Valve type must be selected for system to work.

   Select STANDARD or FAST for valve configurations with a control valve and separate downstream on/off valve(s). Select FAST CLOSE for valve configurations with one valve that combines control and on/off. Selecting the wrong valve type may result in unexpected behavior and degraded performance.

   Control Valve Calibration Table

   Standard Valve Type	Valve Calibration Number (XXYZ)
   RAVEN 165	2513
   RAVEN 894	2513
   RAVEN 125	2513
   TEEJET 344B	1003
   HARDI	7051
   Fast Valve Type	Valve Calibration Number (XXYZ)
   RAVEN 177	0753
   HINIKER Servo Valve (8160 Monitor Compatible)	0433
   Fast-Close Valve Type	Valve Calibration Number (XXYZ)
   RAVEN 177	0753
   HINIKER Servo Valve (8160 Monitor Compatible)	0433

   NOTE: On a RAVEN valve, the last three numbers of the model number are used to identify the valve type (e.g. RAVEN XXX894).

   Use the recommended values in the Control Valve Calibration table to initially set the control valve number. Evaluate machine behavior during operation, and if necessary, adjust the value to attain optimum system performance.

   The Control Valve Calibration number is a 4 digit number used to fine tune control characteristics. The number is in the form XXYZ, and is defined as follows:

   • XX - Valve Speed.
     • The higher this value, the quicker the valve responds. If it is set too high, the actual flow rate will oscillate continuously around the target rate. If it is set too low, the target rate will never be reached.

   • Y - Output Deadband.
     • Sets the minimum speed that the valve will ramp down toward before stopping. The higher this value, the sooner the valve will become stationary.

   • Z - Control Deadband:
     • Sets how close the actual flow rate must be to the target rate to be considered acceptable. When the actual and target rates are within this range, the valve will remain stationary. A higher value allows for a larger disparity between actual and target rate.
   
   

   Example of tuning the control valve for optimal response:After entering the initial starting value for the control valve (e.g. 2513) and run a configuration test, the variance runs high (at or near 100%) and the valve response seems sluggish. The next step in tuning may be to increase the valve speed number (first 2 digits) from 25 to 35 and also increase the output deadband number (third digit) from 1 to 2 and retry the configuration test.

3. Enter maximum volume of tank in input box labeled tank capacity.

4. Select tank capacity displayed units from drop-down menu

5. Select tank capacity units from drop down menu.

   Initial System Settings

   A - Flowmeter Calibration Input Box

   B - Flowmeter Units Drop-Down Menu

   C - Calibrate Flowmeter Button

   D - Pressure Sensor 1 Enable/Disable

   E - Pressure Sensor 2 Enable/Disable

   F - Calibrate Pressure Sensor Button

   Enter Flowmeter Calibration number as stamped on valve.
   • Most flowmeters have an attached tag indicating the recommended calibration number. Enter this number as the initial flowmeter calibration value. It is not necessary to enter an additional product mass conversion value as the controller does it automatically. NOTE: If the tag is no longer attached, start with a low calibration number such as 60, and change the value accordingly from that point.
     NOTE: The number on the RAVEN tag is pulses per 10 units of fluid. Ensure the 10 gal / 10 L unit is used.

7. Choose unit of measurement from flowmeter units drop-down.

8. Check the pressure sensor box if sensor is installed. If using more than one pressure sensor, check the second box as well. Pressure indicator will be displayed on main menu instead of flow rate when pressure sensor is checked.

9. To calibrate pressure sensor, select button and follow on screen instructions. See TEST section for details.
