Important Information: Safety 1
CHAPTER 1 IMPORTANT INFORMATION
SAFETY
Follow the operation and safety instructions included with the implement and/or controller and read this manual
carefully before installing or operating this Raven system.
• Follow all safety information presented within this manual. Review implement operation with your local dealer.
• Contact a local Raven dealer for assistance with any portion of the installation, service, or operation of Raven
equipment.
• Follow all safety labels affixed to system components. Be sure to keep safety labels in good condition and
replace any missing or damaged labels. Contact a local Raven dealer to obtain replacements for safety labels.
Observe the following safety measures when operating the implement after installing this Raven system:
• Do not operate this Raven system or any agricultural equipment while under the influence of alcohol or an
illegal substance.
• Be alert and aware of surroundings and remain in the operator seat at all times when operating this Raven
system. •Do not operate the implement on any public road with this Raven system enabled.
•Disable this Raven system before exiting the operator seat.
•Determine and remain a safe working distance from obstacles and bystanders. The operator is
responsible for disabling the system when a safe working distance has diminished.
•Disable this Raven system prior to starting any maintenance work on the implement or components
of this Raven system.
• Do not attempt to modify or lengthen any of the system control cables. Extension cables are available from a
local Raven dealer.
DISPLAYS AND CONTROL CONSOLES
• If the display will not be used for an extended period, it is best to remove the display from the machine and
store it in a climate controlled environment. This may help to extend the service life of electronic components.
• To prevent theft, secure the display and GPS antenna when leaving the machine unattended.
NOTICE

CHAPTER 1
2VSN® Operation Manual
ELECTRICAL SAFETY
• Always verify that power leads are connected to the correct polarity as marked. Reversing the power leads
could cause severe damage to the Raven system or other components.
• To prevent personal injury or fire, replace defective or blown fuses with only fuses of the same type and
amperage.
• Do not connect the power leads to the battery until all system components are mounted and all electrical
connections are completed.
• Always start the machine before initializing this Raven system to prevent power surges or peak voltage.
• To avoid tripping and entanglement hazards, route cables and harnesses away from walkways, steps, grab bars,
and other areas used by the operator or service personnel when operating or servicing the equipment.
TOUCH SCREEN
• Only touch the touch-screen with your finger or by using a special touch-screen stylus/pen. Operating the
touch-screen with sharp objects may cause permanent damage to the screen.
• Only clean the screen using a damp cloth. Never use caustic or other aggressive substances.
CAUTION

Important Information: Recommendations and Best Practices 3
IMPORTANT INFORMATION
RECOMMENDATIONS AND BEST PRACTICES
HARNESS ROUTING
The word “harness” is used to describe any electrical cables and leads, both bundled and unbundled. Use the
following guidelines and recommendations when connecting and routing harnesses while installing or
maintaining this Raven system:
• Leave protective caps/covers over harness connectors until needed to avoid dirt and moisture from
contaminating electrical circuits.
• Secure the harness to the frame or solid structural members at least every 12 in [30 cm].
• Follow existing harness runs already routed on the implement as much as possible. Proper harness routing
should: •Secure harnessing and prevent the harness from hanging below the implement.
•Provide sufficient clearance from moving components and operational zones around shafts;
universal joints and suspension components; pulleys, gears, belts, and chains; moving linkages,
cylinders, articulation joints, etc.
•Protect harnessing from field debris and surrounding hazards (e.g. tree limbs, fence posts, crop
stubble, dirt clumps or rocks that may fall or be thrown by the implement).
•Protect harnessing from sharp bends, twisting, or flexing over short distances and normal
implement operation.
•Connectors and splices should not be located at bending points or in harness sections that move.
•Ensure sufficient length for free movement of the implement during normal operation and prevent
pulling, pinching, catching, or rubbing, especially in articulation and pivot points. Clamp harnessing
securely to force controlled movement of the harness.
•Avoid abrasive surfaces and sharp edges such as sheared or flame cut corners, fastener threads or
cap screw heads, hose clamp ends, etc.
• Do not connect, affix, or allow harnessing to come into contact with components with high vibration forces, hot
surfaces, or components carrying hot fluids beyond the temperature rating of harness components.
•Harnessing should be protected or shielded if routing requires the hose to be exposed to
conditions beyond harnessing component specifications.
• Avoid routing harnesses in areas where damage may occur due to build up of material (e.g. dirt, mud, snow,
ice, etc.).
• Avoid routing harnesses in areas where the operator or service personnel might step or use as a grab bar.
IMPORTANT: Avoid applying direct spray or pressure washing of electrical components and connections. High pressure
streams and sprays can penetrate seals, cause corrosion, or otherwise damage electrical components.
When performing maintenance:
• Inspect electrical components and connectors for corrosion, damaged pins or housings, etc. Repair or replace
components or harnessing as necessary.
• Ensure connectors are kept clean and dry. Apply dielectric grease to the sealing surfaces of all connections
exposed to moisture, dirt, debris, and other contaminates. Repair or replace harnessing as necessary.
• Clean electrical components with pressurized air, aerosol electrical cleaning agent, or low pressure rinse.
• Remove visible surface water from electrical components and connections using pressurized air or an aerosol
cleaning agent. Allow components to dry thoroughly before reconnecting cables.

When coupled with a Raven field computer and RS1/SC1, VSN® is designed to offer hands-free steering of
agricultural sprayers and cultivator implements.
NOTE: Implement steering is only supported with a CR12 and an SC1 steering system.
The chapters in this manual are intended to assist with the proper calibration and operation of the VSN system.

Introduction: Weed Coverage 7
INTRODUCTION
WEED COVERAGE
Plant rows need to be clearly distinguishable from the weeds by eye. When plant rows are difficult to distinguish
from the weeds, the VSN® camera can have issues recognizing rows. When weeds grow in rows, the VSN®
camera can confuse the weed rows with the actual plant rows. The image below shows row recognition quality as
an example.
TABLE 3. Weed Recognition
INSTALLATION
RECOMMENDATIONS
Raven Industries recommends the following best practices when installing or operating the VSN system for the
first time, at the start of the season, or when moving the VSN system to another machine:
• Verify that the hydraulic system is using fresh oil and that the filters have been recently changed.
• Ensure there are no issues with the hydraulic system (e.g. pump issues, faulty hydraulic motors, fine metal
deposits in the hydraulic hoses, etc.).
• Ensure there are no issues with the steering system (worn bushings, faulty tie rod ends, improperly adjusted
steer components, etc.).
WARNING
Carefully read and follow all safety requirements
and precautions contained in this manual and the
machine-specific or implement Installation
Manual. Failure to follow safety instructions may
lead to equipment damage, personal injury, or
death.

CAMERA MOUNTING RECOMMENDATIONS
The settings for camera angle and camera height may affect the accuracy of the camera measurement and the
row recognition quality.
The settings in the following table are recommended minimum and maximum camera mounting heights.
Minimum heights mean the lowest possible camera height required to cover at least three rows in the field of view.
For row spacings between 4.92 in [12.5 cm] to 39.37 in [100cm], which are not given in the table below, the camera
height can be interpolated.

CARE AND MAINTENANCE
GLASS CARE AND CLEANING
• Avoid pressure washing the camera lens.
• Use any glass cleaning products with a soft cloth. Avoid any abrasive products that could scratch or damage
the glass.
RADAR SENSORS
• If the system does not allow the operator to engage while using radar sensors, use a rag or cloth to clean the
radar sensors and allow for better solution quality.
