17 Preparation and Setup
Raven SCS 450 and 440
The Raven SCS 450 and 440 (Sprayer Control
System) are designed to improve the uniformity of
spray applications. Its performance relies on the
installation and preventive maintenance of the
complete sprayer. An installation and service
manual are provided with this sprayer. It is impor-
tant to read and understand this manual before
operating the system.
Note: Refer to the Raven SCS 450 and 440 man-
ual for step-by-step instructions for installing and
operating.
The SCS 450 and 440 systems consist of a com-
puter-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 tractor for easy operator use. The Radar
Speed Sensor is mounted to the frame of the trac-
tor or sprayer (wheel drive and speedometer
Drive Speed Sensors are also available.) The mo-
torized Control Valve and Flow Meter mount to the
framework supporting the boom valves. Appropri-
ate cabling is furnished for field installation.
The operator sets the target volume per area to be
sprayed and the SCS 450 and 440 automatically
maintain 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 450 and 440 additionally function as an area
monitor, speed monitor and volume totalizer.
