INTRODUCTION

The Raven SCS 460 (SPRAYER CONTROL SYSTEM) is designed to improve the uniformity of spray

applications. Its performance relies on the installation and preventive maintenance

of the complete sprayer. It is important that this Installation and Service Manual be

reviewed thoroughly before operating the system. This manual provides a simple step-

by-step procedure for installing and operating.

The SCS 460 system consists of a computer-based Control Console, a Speed Sensor, a turbine

type Flow Meter and a motorized Control Valve. The Console mounts directly in the cab

of the vehicle for easy operator use. The Speed Sensor is mounted on a non-driven wheel

of the tractor or on a wheel of the sprayer implement. (Other Speed Sensors also

available). The motorized Control Valve and Flow Meter mount to the framework supporting

the boom valves. Appropriate cabling is furnished for field installation.

The operator sets the target volume per area to be sprayed and the SCS 460 automatically

maintains the flow regardless of vehicle speed or gear selection. A manual override

switch allows the operator to manually control flow for system check-out and spot

spraying. Actual volume per area being applied is displayed at all times. The SCS 460

additionally functions as an area monitor, speed monitor, and volume totalizer.

NOTE: The SCS 460 Control Console is designed to be used with external Boom

switches. In order for the Console to know when and which Boom is ON

or OFF, Boom signal wires are provided.
