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.

INSTALLATION
1. MOUNTING THE RAVEN RADAR SPEED SENSOR
See Appendix 8 for Wheel Drive Speed Sensor installation instructions.
See Appendix 9 for Speedometer Drive Speed Sensor installation instructions.
For mounting the Radar, the following guidelines will assure proper installation:
It is suggested that a large heavy mounting bracket, (P/N 107-0159-693) be attached
to the vehicle frame for mounting the Radar.
1) Park vehicle on level surface.
2) Select mounting site by considering the following:
a) The line of sight from the lens to the ground must not be obstructed by
structures or tires. Obstructions must not come closer than 20 inches to
the bottom of the Radar. See Figures 1 and 2.
b) The Radar lens must be parallel to the ground from front to back. Radar
can be tilted out 0-15 degrees to provide more clearance and miss
obstructions. See Figure 2.
c) The Radar should be mounted so that the length of the Radar is parallel with
direction of vehicle travel.
3) Use carpenters level to verify that mounting bracket is parallel to the ground.
4) Bolt mounting bracket to implement.
5) Bolt Radar to mounting bracket using mounting hardware. See Figure 3.
6) Connect Radar with Radar Interface Cable (P/N 115-0159-539) to the Console. The
Red wire should be connected to the Orange cable wire. The White wire should be
connected to the negative terminal of the battery. See Figure 10.
CAUTION: The connection of the Radar power in reverse polarity could result
in damage to the Radar.

2. MOUNTING THE ENCODER
1) Mount Encoder on output shaft of conveyor, or other shaft which rotates at a known
ratio to the conveyor. (See Figures 5,6,7,& 8).
2) Apply grease to Encoder shaft, conveyor shaft, and Encoder coupler (fits 1"
diameter conveyor shaft). Secure coupler to Encoder and conveyor shafts with set
screws provided.
3) Install mounting tabs to Encoder as shown in Figure 4. Connect mounting tab to
mounting bracket (not provided) to prevent Encoder from rotating. DO NOT rigidly
mount Encoder. Encoder is to be supported by coupler ONLY.

CONSOLE CALIBRATION
1. CALCULATING "BOOM CAL"
Enter the total width of the spread pattern in inches [cm] as boom length (See
"Definition of Boom Calibration keys").
2. CALCULATING "SPEED CAL"
Initial SPEED CAL is 598 [152]. Complete Steps 1 thru 6 to refine this number
after section "INITIAL CONSOLE PROGRAMMING" has been completed.
1) Set POWER switches to ON, all other switches to OFF.
2) Enter "0" in key labelled
3) Drive 1 mile [1 kilometer]. To achieve the most accurate calibration, accelerate
and decelerate slowly.
CAUTION: Do not use vehicle odometer to determine distance. Use section
lines or highway markers.
4) Read DISTANCE by depressing key labelled
DISTANCE should read a value of approximately 5280 [1000]. If it reads between
5260-5300 [990-1010], the SPEED CAL for the vehicle is 598 [152]. If the DISTANCE
display reads any other value, perform the following calculation:
EXAMPLE: Assume DISTANCE reads 5000 [980].
Corrected SPEED CAL = Old SPEED CAL x 5280
DISTANCE
ENGLISH UNITS: METRIC UNITS:
= 598 x 5280 = 631.48 = [152] x [1000] = [155]
5000 [980]
5) The number to enter for SPEED CAL is 631 [155].
6) Recheck the new SPEED CAL derived in Step 5 by repeating Steps 2 thru 5.

11
3. CALCULATING "SPREADER CONSTANT"
1) For RATE displayed in 1 lb [1 kg] increments:
L = Length in inches [centimeters], of belt travel per 1 revolution of Encoder
GH = Gate Height in inches [centimeters]
GW = Gate Width in inches [centimeters]
English (US) : Metric (SI):
Spreader Constant = 311,040 Spreader Constant = [18,000,000]
(1 lb) L x GH x GW (1 kg) [L] x [GH] x [GW]
EXAMPLE: 1) L = 13 inches [33 cm]
2) GH = 7 inches [18 cm]
3) GW = 15 inches [38 cm]
English (US):
Spreader Constant (1 lb) = 311,040
13 x 7 x 15
=311,140 = 228
1365
Metric (SI):
Spreader Constant (1 kg) = [18,000,000]
[33] x [18] x [38]
=[18,000,000] = [797]
[22,572]
NOTE: Verify Spreader Constant by performing Spreader Constant calibration
procedure in Appendix 7 before field application.
4. CALCULATING "METER CAL"
Product Density in lbs/cu.ft. [grams/liter] is entered as METER CAL.
NOTE: To increase the system accuracy when applying at low rates, use the
decimal shift feature as explained in CONSOLE PROGRAMMING.

12
5. CALCULATING "VALVE CAL"
1) The initial Control Valve calibration number is 2123 for C-Sd, or 743 for C-FC.
After operating the system, you may desire to refine this number. See definitions
below:
For FAST VALVE (C-F or C-FC):For STANDARD VALVE (C-Sd):
Valve Backlash Digit Controls the time of the first correction pulse after
a change in correction direction is detected.
(INC to DEC
-or- DEC to INC).
Range: 1 to 9 1-Short Pulse
9-Long Pulse
Valve Speed Digit Controls response time of Control Valve motor.
CAUTION: Running the Control Valve too fast will
cause the system to oscillate.
C-Sd Valve Control Product 1 Range: 1 to 9 1-Slow
9-Fast
C-F or C-FC Valve Control Product 2-5 Ranges: 0 to 9 0-Fast
9-Slow
Brake Point Digit Sets the percent away from target rate at which the
Control Valve motor begins turning at a slower rate, so
as not to overshoot the desired rate.
Range: 0 to 9 0 = 5%
1 = 10%
9 = 90%
Dead-Band Digit Allowable difference between target and actual applica-
tion rate, where rate correction is not performed.
Range: 1 to 9 1 = 1%
9 = 9%
6. CALCULATING "RATE CAL"
The application rate in lbs/acre [kg/ha] is entered as RATE CAL. Consult the
equipment manual to insure that the selected gate opening is capable of applying
at this application rate.
NOTE: The Spreader Constant must be recalculated anytime the gate opening is
changed.
