INTRODUCTION
The Raven SCS 661 (CONTROL SYSTEM) is designed to improve the uniformity of spray and granular
applications. Its performance relies on installation and preventive maintenance of the complete sprayer or
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 661 liquid system consists of a Control Console, a Speed Sensor, a turbine type Flow Meter, and
a motorized Control Valve. The SCS 661 granular system 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 tractor or sprayer (Other Speed
Sensors are also available). For liquid systems the Motorized Control Valve and Flow Meter mount to the
framework supporting the Boom Valves. For granular systems, 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 volume per area to be sprayed or weight per area to be applied and the SCS
661 automatically maintains the correct application rate regardless of vehicle speed or gear selection. A
manual override switch allows the operator to manually control the rate for system checkout and spot
application. Actual volume or weight per area being applied is displayed at all times. The SCS 661
additionally functions as an area monitor, speed monitor, and volume totalizer.
NOTE:
The SCS 661 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.
