Important Safety

Information

Important Safety Information

Read this manual and the operation and safety instructions included with your implement and/or controller

carefully before installing the SCS 450 Serial Interface system.

•Follow all safety information presented within this manual.

•If you require assistance with any portion of the installation or service of your Raven equipment, contact

your local Raven dealer for support.

•Follow all safety labels affixed to the system components. Be sure to keep safety labels in good condition

and replace any missing or damaged labels. To obtain replacements for missing or damaged safety labels,

contact your local Raven dealer.

When operating the machine after installing the SCS 450 Serial Interface system, observe the following safety

measures:

•Be alert and away of surroundings.

•Do not operate the SCS 450 Serial Interface system while under the influence of alcohol or an illegal

substance.

•Remain in the operator’s position in the machine at all times when the SCS 450 Serial Interface system is

engaged.

•Determine and remain a safe working distance from other individuals. The operator is responsible for

disabling the SCS 450 Serial Interface system when the safe working distance has been diminished.

•Ensure the SCS 450 Serial Interface is disabled prior to starting any maintenance work on the machine or

parts of the SCS 450 Serial Interface system.

•Follow all label instructions for proper chemical mixing, handling, and container disposal methods.

NOTICE

Chapter 1

2 SCS 450 Serial Interface Installation & Service Manual

Thoroughly bleed the nurse tank hose and all other system lines prior to disassembling the flow meter, fittings,

and hoses, especially in the case of anhydrous ammonia.

Hydraulic Safety

•Raven Industries recommends that appropriate protective equipment be worn at all times when working on

the hydraulic system.

•Never attempt to open or work on a hydraulic system with the equipment running. Care should always be

taken when opening a system that has been previously pressurized.

•When disconnecting the hydraulic hoses or purging is required, be aware that the hydraulic fluid may be

extremely hot and under high pressure. Caution must be exercised.

•Any work performed on the hydraulic system must be done in accordance with the machine manufacturer’s

approved maintenance instructions.

•When installing AutoBoom hydraulics or performing diagnostics, maintenance, or routine service, ensure

that precautions are taken to prevent any foreign material or contaminants from being introduced into the

machine’s hydraulic system. Objects or materials that are able to bypass the machine’s hydraulic filtration

system will reduce performance and possibly damage the hydraulic valves.

Electrical Safety

•Always verify that the power leads are connected to the correct polarity as marked. Reversing the power

leads could cause severe damage to the equipment.

•Ensure that the power cable is the last cable to be connected.

•Disconnect the SCS 450 Serial Interface console before jump-starting the vehicle.

•Disconnect the SCS 450 Serial Interface console before welding any component of the machine.

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

[200] x [40] = 80 lit/ha

[100]

Chapter 2

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
