INTRODUCTION
The Raven SCS 660 (CONTROL SYSTEM) is designed to improve the uniformity of granular
applications. Its performance relies on installation and preventive maintenance of the
complete spreader. 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 660 consists of a Control Console, a Speed Sensor, an Encoder, and a Hydraulic
Control Valve. The Console mounts directly in the cab of the vehicle for easy operator
use. The Radar Speed Sensor is mounted to the frame of the spreader implement. (Other
Speed Sensors are also available). The Hydraulic Control Valve mounts to the framework
of the vehicle and the Encoder mounts to the conveyor drive shaft. Appropriate cabling
is furnished for field installation.
The operator sets the target weight per area to be applied and the SCS 660 automatically
maintains the application regardless of vehicle speed or gear selection. A manual
override switch allows the operator to manually control application for system check-
out and spot application. Actual weight per area being applied is displayed at all times.
The SCS 660 additionally functions as an area monitor, speed monitor, and volume
totalizer.
NOTE: The SCS 660 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.
