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. Inorder for the Console to know when andwhichBoomisON or OFF,
Boom signal wires are provided.

INSTALLATION
1. MOUNTING THE RAVEN RADAR SPEED SENSOR
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) ConnectradarwithRadarInterfaceCable(P/N115-0159-539),totheConsole. TheRedwireshould
be connected to the Orange cable wire. The White wire should be connected to the White cable
wire (See "BATTERY CONNECTIONS").
CAUTION: The connection of the radar power in reverse polarity could result in damage to
the radar.

2. MOUNTING THE FLOW METER (Liquid Applications)
1) Mount Flow Meter in the area of the boom valves per Figure 4. All flow through Flow Meter must go
to booms only, i.e., no return line to tank or pump after Flow Meter.
2) Mount Flow Meter horizontal to the ground. Use the bracket to secure the Flow Meter.
3) For best results, allow a minimum of 7 1/2 inches [20 cm] of straight hose on inlet of Flow Meter.
Bend radius of hose on outlet of Flow Meter should be gradual.
4) Flow must be in direction of arrow on Flow Meter.
3. MOUNTING THE CONTROL VALVE (Liquid Applications)
1) Mount the motorized Control Valve in the main hose line between the Flow Meter and the booms,
with motor in the upright position.
2) Connect the Vehicle Cable connectors to boom valves, Flow Meter, and motorized Control Valve.

NOTE: It is critical, when using suspensions, that the system be thoroughly rinsed out
each day after use.

4. MOUNTING THE ENCODER (Granular Applications)
1) Mount Encoder on output shaft of conveyor, or other shaft which rotates at a known ratio to the
conveyor. (See Figures 6,7, 8 & 9).
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 5. 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.

5. MOUNTING THE HYDRAULIC CONTROL VALVE (Granular
Applications)
1) Refer to Figures 6,7, 8 & 9 for typical placement of the Hydraulic Control Valve.
2) Valve is to be mounted with motor in the upright position.

6. MOUNTING THE CONSOLE AND CABLING
1) Mount the Console and Switch Box to a secure support inside the cab of the vehicle.
2) Connect the Console Control Cable to the plug in the back of the Console. (See Figure 10). Route
the Console Control Cable out of the vehicle cab and connect with vehicle connectors.

3. CALCULATING "SPEED CAL"
Initial SPEED CAL is 598 [152]. Complete Steps 1 thru 6 to refine this number after "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:
DISTANCEshouldreadavalueofapproximately5280[1000]. Ifitreadsbetween5260-5300[990-
1010],theSPEEDCAL forthe vehicleis598 [152]. Ifthe DISTANCEdisplayreadsanyother 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.
4. CALCULATING"METER CAL"
LIQUID APPLICATIONS
1) When calculating METER CAL refer to the Flow Meter calibration number which is stamped on the
label attached to the Flow Meter. This number is to be used for gallon per area applications.
Toconvertoriginal METER CAL from gallons to desired unitsof measure(oz, lbs,or liters perarea)
see "METER CAL CONVERSIONS".
Write down this calibration number for future reference when programming the Console.
GRANULAR APPLICATIONS
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.

14
5. CALCULATING "SPREADER CONSTANT" (Granular Appli-
cations)
1) For RATE displayed in 1 lb [1 kg] increments:
L = Length in inches [centimeters], of belt travel per 1 revolution of Sensor
GH = Gate Height in inches [centimeters]
GW = Gate Width in inches [centimeters]
CPR = Counts per 1 revolution of sensor
English (US) : Metric(SI):
Spreader Constant = CPR x 1728 Spreader Constant = [CPR x 100,000]
(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]
4) CPR = 180
English (US):
Spreader Constant (1 lb) = 180 x 1728
13 x 7 x 15
=311,140 = 228
1365
Metric (SI):
Spreader Constant (1 kg) = [180 x 100,000]
[33] x [18] x [38]
=[18,000,000] = [797]
[22,572]
Counts per one revolution of sensor (CPR) may be determined by entering a METER CAL of 10, enter 0
inTOTALVOLUMEandturningsensorexactlyonerevolution. ThenumberinTOTALVOLUMEwillbethe
CPR. Thiscalculation canbeperformed whiledetermininglength ofbelttravel peronerevolution of sensor
(L).
NOTE: Verify Spreader Constant by performing Spreader Constant calibration proce-
dure in Appendix 9 before field application.
