INTRODUCTION
The Raven SCS 340 (SPRAYER CONTROL SYSTEM) is designed to improve the uniformity of spray
applications automatically. 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 340 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 Raven Radar Speed Sensor is mounted on the vehicle
or on the sprayer implement (Speedometer Drive Speed Sensors and Wheel Drive Speed
Sensors are also available). The motorized Control Valve and Flow Meter mount directly
to the framework of the sprayer. Appropriate cabling is furnished for field
installation.
The operator sets the target rate (volume per area) to be sprayed and the SCS 340
automatically maintains the flow regardless of vehicle speed or gear selection (within
range of selected spray nozzles). A manual override switch allows the operator to
manually control flow for system check-out and spot spraying. The SCS 340 additionally
functions as an area monitor, speed monitor, and volume totalizer.
