Introduction

Congratulations on your purchase of the Raven SCS (Sprayer Control System) 450 Serial Interface! The

Raven SCS 450 is designed to provide uniformity of spray applications, regardless of the vehicle’s speed.

Utilizing a computer-based console, a speed sensor, a turbine-type flow meter, and a motorized control valve,

the SCS 450 also functions as an area monitor, speed monitor, and volume totalizer.

The operator sets the target volume per area to be applied, and the SCS 450 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 450 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

Calculating 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

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:

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.

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]

6 SCS 450 Serial Interface Installation & Service Manual

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
