Introduction

Congratulations on your purchase of the Raven SCS (Sprayer Control System) 440 Serial Interface! The Raven SCS 440 is designed to provide uniformity of spray applications, regardless of the vehicle’s speed. Utilizing a computer-based console, a speed sensor, a flow meter, and a control valve, the SCS 440 also functions as an area monitor, speed monitor, and volume totalizer.

The operator sets the target volume area to be applied, and the SCS 440 automatically maintains the flow. A manual override switch allows the operator to manually control the flow for spot-spraying. The actual volume per area being applied is displayed at all times on the console.

NOTICE

The performance of the SCS 440 relies on the proper installation and preventative maintenance of the system and the sprayer. Review this Installation & Service Manual thoroughly before operating the system.

Introduction

Calculate the Machine’s Calibration Values

Calculate the Boom Cal Value

Broadcast Spraying

Calculate the Boom Cal value in inches [cm] by multiplying the number of tips by the spacing between the tips. Be sure to write down these figures for future reference when programming the console.

FIGURE 1. Boom Sections

Band Spraying

2

Calculate the Boom Cal value in inches [cm] by multiplying the number of tips by the spacing between the tips. Calculate the Adjusted Applied Rate by multiplying the Broadcast Rate by the Band Width in inches [cm], then divide by the spacing in inches [cm].

For Example:

Broadcast Rate	= 20 GPA [200 lit/ha]
Spacing	= 40 inches [100 cm]
Band Width	= 14 inches [40 cm]
GPA x Band Width	=		Adjusted Applied Rate
Spacing
20 x 14	=		7 GPA
40
[200] x [40]	=		80 lit/ha
[100]

Calculate the Speed Cal Value

Raven Radar Only

The initial Speed Cal value for Raven radar is 598 [152]. After the initial console programming has been performed, this value may be adjusted to optimize the system’s performance.

Manual No. 016-0159-822

Chapter 2

Phoenix 10 Speed Sensors Only

The initial Speed Cal value for Phoenix 10 speed sensors is 785 [200]. After the initial console programming has been performed, this value may be adjusted to optimize the system’s performance.

Wheel Drive Speed Sensors Only

Important: This procedure should be performed only after the entire system installation is complete. This procedure is critical to the console’s performance, so measure carefully. This procedure should be performed on the same soil conditions in which you will be spraying, since wheel circumference varies in soft soil versus hard-packed soil.

FIGURE 2. Speed Cal Value Calculation

1.Place a chalk mark or tape on the tire on which the speed sensor is mounted.

2.Mark the spot on the ground directly below the chalk mark or tape.

3.Drive the machine straight ahead, counting 10 full rotations of the wheel.

Important: The mark must stop at the same position (with the chalk mark or tape perpendicular to the ground at the bottom of the tire) as before it was before the measurement began.

4.Measure the distance (in inches/cm) from the ground starting mark to the stopping mark. Round off fractions of an inch/cm.

5.Write down this number as it will be used as the Speed Cal value when programming the console.

Note: Large tires and very low speed applications may require additional magnets to ensure accurate speed readings. Any even number of magnets may be used as long as they alternate in color and are equally spaced. After calculating the Speed Cal value, the number must be adjusted according to the actual number of magnets used.

For Example:

Normal Number of Magnets			x	Calculated Speed Cal	= Adjusted Speed Cal
Actual Number of Magnets
4	x 1200	=	800

Introduction

Calculate the Meter Cal Value

No calculation of the Meter Cal value is necessary, since the flow meter calibration value is stamped on the tag attached to each flow meter. Locate this number and write it down for future reference when programming the console.

Calculate the Valve Cal Value

The Valve Cal figure is used to control the response time of the control valve motor to the change in the vehicle’s speed. After operating the system, this number may be refined. The initial recommended control valve values are:

•C-SD (standard valve) = 2123

•C-FC (fast-close valve) = 743

•C-F (fast valve) = 743

•C-P (PWM valve) = 43

•C-PC (PWM close valve) = 43

Calculate the Rate 1 and Rate 2 Cal Values

Determine the application rate at which the chemical is to be sprayed, and then consult with your Raven dealer to verify that the spray nozzles are capable of applying at that rate. To determine which spray nozzles to use with the sprayer, the following information must be known:

Nominal Application Pressure		PSI (kpa)
Target Application Rate		GPA (lit/ha)
Target Speed		MPH (km/h)
Nozzle Spacing		inches (cm)

With this information, calculate the volume per minute, per nozzle using the following formula:

GPA (lit/ha) x MPH (km/h) x inches (cm)	= GPM (lit/min)
5,940 [60,000]

Refer to the following chart to determine which nozzle to use based on the desired output.

For Example:

Nominal Application Pressure	30	PSI (kpa)
Target Application Rate	20	GPA (lit/ha)
Target Speed	5.2	MPH (km/h)
Nozzle Spacing	20	inches (cm)
20 GPA x 5.2 MPH x 20 inches			= .35 GPM
5,940

Based on these calculations and a PSI of 30, tip XR8004 should be selected since it comes closest to providing the desired output.
