INTRODUCTION
The Raven SCS 460 (SPRAYER CONTROL SYSTEM) is designed to improve the uniformity of spray
applications. Its performance relies on the installation and preventive maintenance
of the complete sprayer. It is important that this Installation and Service Manual be
reviewed thoroughly before operating the system. This manual provides a simple stepby-step procedure for installing and operating.
The SCS 460 system consists of a computer-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 vehicle for easy operator use. The Radar Speed Sensor is mounted to the frame
of the vehicle or implement (wheel drive and speedometer Drive Speed Sensors are also
available.) The motorized Control Valve and Flow Meter mount to the framework supporting
the boom valves. Appropriate cabling is furnished for field installation.
The operator sets the target volume per area to be sprayed and the SCS 460 automatically
maintains 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 460
additionally functions as an area monitor, speed monitor and volume totalizer.
NOTE: The SCS 460 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 1 for Wheel Drive Speed Sensor installation instructions.
See Appendix 2 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.
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 White cable wire (See "BATTERY CONNECTIONS").
CAUTION:
See Figure 3.
The connection of the radar power in reverse polarity could result
in damage to the Radar.

Depress
until display shows SET LOW LIMIT 0. A low limit flow rate may
now be entered. If the actual volume per minute falls below this limit, the Control
Valve stops closing, an alarm sounds, and the display flashes LOW LIMIT. The
low limit value should be determined with all booms ON. This value is automatically
proportional to the percentage of booms that are ON. (i.e. If the entered low
limit is 4 and half the total boom length is shut off, the Console automatically
reduces the low limit to 2).
NOTE: Go to DATA MENU to silence alarm.

CONTROL VALVE DELAY
Depress
until display shows CONTROL VALVE DELAY.
The first digit,
( X 0 0 0 ), is the Control Valve delay digit. This feature allows the user to
set a delay between the time the booms are turned ON and when the Console begins
to control the flow rate. A value of 1-9 means a delay of 1-9 seconds respectively.
A value of 0 means no delay. This delay is active if the time between turning
OFF and turning ON the booms is less than 30 seconds.
9.
ZERO SPEED SHUT-OFF
This function will be active when C-FC (Fast Close Valve) or C-PC (PWM Close Valve)
is selected. This function can not be disabled. When C-FC or C-PC has been
selected, the valve will receive a decrease signal and run closed when the speed
drops to .7 MPH or less. The only way the console can operate at .7 MPH or less
is in the manual mode.
When a zero speed shut-off has occured, the MASTER switch must be turned OFF and
then ON to restart the system. If a constant speed greater than .7 MPH is not
attained within 10 seconds, the zero speed shut-off will be enacted again.

RIM DRILLING INSTRUCTIONS FOR WHEEL DRIVE SPEED
SENSOR MAGNETS
On wheels which do not have pre-punched mounting holes, proceed as follows:
RIMS WITH FOUR OR EIGHT HOLE STUD PATTERN:
Choose stud holes that are opposite each other as shown below. Using the center
of opposite holes, scribe two lines on the rim web to divide the circumference
into four equal parts. Measure in one inch from the outer edge of the web on each
of the lines drawn. Mark this point as the center. Drill four 1/2" holes for
mounting the magnets.
NOTE: Distance (D) between each set of drilled holes must be equal within
1/8 [3 mm] to ensure accuracy of system.
RIMS WITH SIX HOLE STUD PATTERN:
Locate the center of the holes to be drilled by using the rim webbing as a guide.
Obtain a small piece of wood and cut to fit exactly over the web as shown. Measure
the length of the piece of wood and mark the center on one edge. Using the center
mark on the piece of wood, mark each of the four webs. Measure in one inch from
the outer edge of the web on each of the lines drawn. Mark this point as center
and drill four 1/2" holes for mounting the magnets.
NOTE: Distance (D) between each set of drilled holes must be equal within
1/8" [3 mm] to ensure accuracy of system.

CALCULATING "SPEED CAL"
1)
Place a chalk mark or tape onto the vehicle tire that the Speed Sensor mounted
to it as shown below.
2)
Mark the initial spot on the ground.
3)
Drive vehicle straight ahead counting 10 full revolutions of the wheel. The mark
must stop at the same position it was in when the vehicle started.
4)
Measure the distance from the ground starting mark to stopping mark in inches [dm]
(Round off fractions).
5)
Write down this distance as the SPEED CAL number; keep it for future reference
when programming the Console.
NOTE: This measurement is critical to the performance of the Console. MEASURE
CAREFULLY. Be sure tire is properly inflated before measuring. Measure
tire in type of soil in which you will be spraying. Circumference of
tire will vary when measured in soft soil versus hard packed soil. For
best results, measure several times and average the results.
Large tires and very low speed applications may require additional magnets to
insure accurate speed readings. Any even number of magnets may be used as long
as they are of alternating color and equally spaced. After calculating "SPEED
CAL", this number must be adjusted according to the number of magnets used.
Normal Number of Magnets
Actual Number of Magnets
Example:
4
6
x Speed Cal = Adjusted Speed Cal
x 1200 = 800
SCS 330, SCS 500 and SCS 550 normally use two magnets. All other consoles normally
use four magnets.

APPENDIX 2
PROCEDURE TO TEST SPEED SENSOR EXTENSION CABLES
Verify that the Console is in the SP1 Speed Sensor mode while testing the cable.
Disconnect extension cable from Speed Sensor Assembly cable. Hold extension cable
connector so that keyway is pointing in the 12 o’clock position.
PIN DESIGNATIONS
2 o’clock socket location is power.
10 o’clock socket location is ground.
6 o’clock socket location is signal.
VOLTAGE READINGS
1) 10 o’clock socket to 6 o’clock socket = +5 VDC.
2) 10 o’clock socket to 2 o’clock socket = +5 VDC.
If a +5 VDC voltage reading is not present, disconnect
the Flow Sensor cable.
If the Speed reading is
restored, Test the Flow Sensor cable per Appendix
"PROCEDURE TO TEST FLOW METER CABLES".
PROCEDURE TO CHECK CABLE:
l)
Enter SPEED CAL number of 1000 in key labelled
2)
Depress key labelled
3)
With small jumper wire (or paper clip), short between the 10 o’clock and 6 o’clock
sockets with a "short-no short" motion. Each time a contact is made, the DISTANCE
total should increase by increments of 1 or more counts.
4)
If DISTANCE does not increase, remove the section of cable and repeat test at
connector next closest to Console. Replace defective cable as required.
5)
Perform above voltage checks.
6)
If all cables test good, replace Speed Sensor.
NOTE: After testing is complete, re-enter correct SPEED CAL number before
application.

APPENDIX 3
PROCEDURE TO TEST FLOW METER CABLES
Disconnect cable from Flow Sensor. Hold Flow Sensor cable so that the keyway is
pointing in the 12 o’clock position:
PIN DESIGNATIONS
2 o’clock socket location is ground.
10 o’clock socket location is power.
6 o’clock socket location is signal.
VOLTAGE READINGS
1) 2 o’clock socket to 6 o’clock socket = +5 VDC.
2) 2 o’clock socket to 10 o’clock socket = +5 VDC.
If a +5 VDC voltage reading is not present, disconnect
the Speed Sensor cable.
If the Flow reading is
restored, Test the Speed Sensor cable per Appendix
"PROCEDURE TO TEST SPEED SENSOR EXTENSION CABLES".
PROCEDURE TO CHECK CABLE:
1)
Enter a METER CAL number of one (1) in key labelled
2)
Depress key labelled
3)
Place BOOM switches to ON.
4)
With small jumper wire (or paper clip), short between the 2 o’clock and 6 o’clock
sockets with a "short-no short" motion. Each time a contact is made, the TOTAL
VOLUME should increase by increments of 1 or more counts.
5)
If TOTAL VOLUME does not increase, remove the section of cable and repeat test
at connector next closest to Console. Replace defective cable as required.
6)
Perform above voltage checks.
7)
If all cables test good, replace Flow Sensor.
NOTE: After testing is complete, re-enter correct METER CAL numbers before
application.

APPENDIX 4
FLOW METER MAINTENANCE AND ADJUSTMENT PROCEDURE
1)
Remove Flow Meter from sprayer and flush with clean water to remove any chemicals.
NH3 WARNING: Thoroughly bleed nurse tank hose and all other system lines prior
to disassembling the Flow Meter, fittings, and hoses.
2)
Remove flange bolts or clamp from the Flow Meter.
3)
Remove the turbine hub and turbine from inside Flow Meter.
4)
Clean turbine and turbine hub of metal filings or any other foreign material, such
as wettable powders. Confirm that the turbine blades are not worn. Hold turbine
and turbine hub in your hand and spin turbine. The turbine should spin freely
with very little drag inside the turbine hub.
5)
If transducer assembly is replaced or if turbine stud is adjusted or replaced,
verify the turbine fit before reassembling. Hold turbine hub with turbine on
transducer. Spin turbine by blowing on it. Tighten turbine stud until turbine
stalls. Loosen turbine stud 1/3 turn. The turbine should spin freely.
6)
Re-assemble Flow Meter.
7)
Using a low pressure (5 psi) [34.5 kPa] jet of air, verify the turbine spins freely.
If there is drag, loosen hex stud on the bottom of turbine hub 1/16 turn until
the turbine spins freely.
8)
If the turbine spins freely and cables have been checked per Appendix "PROCEDURE
TO TEST FLOW CABLES", but Flow Meter still is not totalizing properly, replace
Flow Meter transducer.
38
APPENDIX 5
PROCEDURE TO RE-CALIBRATE FLOW METER
1)
Enter a METER CAL number of 10 [38] in the key labelled
2)
Enter a TOTAL VOLUME of 0 in the key labelled
3)
Switch OFF all booms.
4)
Remove a boom hose and place it into a calibrated 5 gallon [19 liter] container.
5)
Switch ON appropriate boom switch (for the hose that was just placed into the 5
gallon container) and the MASTER switch. Pump exactly 10 gallons [38 liters].
6)
Readout in TOTAL VOLUME is the new METER CAL number. This number should be within
+/- 3% of the calibration number stamped on the tag of the Flow Meter.
7)
Repeat this procedure several times to confirm accuracy. (Always "zero out" the
TOTAL VOLUME display before retesting).
NOTE: For greatest precision, set METER CAL to 100 and pump 100 gallons (378
liters) of water.
8)
To verify Flow Meter calibration, fill applicator tank with a predetermined amount
of measured liquid (i.e. 250 gallons). DO NOT RELY ON GRADUATION NUMBERS MOLDED
INTO APPLICATOR TANK.
Empty the applicator tank under normal operating
conditions. If the number displayed under TOTAL VOLUME is different from the
predetermined amount of measured liquid by more than +/- 3%, complete the following
calculation:
EXAMPLE:
METER CAL
TOTAL VOLUME
Predetermined amount of measured liquid
Corrected METER CAL
=
METER CAL x TOTAL VOLUME
Predetermined amount of measured liquid
ENGLISH UNITS:
= 720 x 260 = 749

= 720 [190]
= 260 [984]
= 250 [946]
METRIC UNITS:
= [190] x [984] = [198]
[946]
= 749 [198]
Enter corrected METER CAL before resuming application.
