SERVICE MANUAL
N O T I C E
The use of the suspension type slurries will significantly reduce
the life of the plastic parts in the Flow Meter and motorized
Control Valve. Check the rotor and inlet hub assembly in the Flow
Meter frequently for worn parts. Excessive wear can affect
accuracy.
Do not attempt to modify or lengthen any of the three-wire Speed
Sensor or Flow Meter cables. Extension cables are available from
your Dealer.

SYMBOL DEFINITION
LIQUID METER CAL CONVERSIONS
To convert the METER CAL number simply divide the original number (number printed
on Flow Meter label) by the desired conversion factor.
FOR EXAMPLE:
Original METER CAL No. = METER CAL No. for displays in Fluid Ounces
128
Original METER CAL No. = METER CAL No. for displays in Liters
3.785
Original METER CAL No. = METER CAL No. for displays in Pounds
Weight of one gallon
LIQUID CONVERSIONS
U.S. Gallons x 128 = Fluid Ounces
U.S. Gallons x 3.785 = Liters
U.S. Gallons x 0.83267 = Imperial Gallons
U.S. Gallons x 8.34 = Pounds (Water)
LENGTH
1 millimeter (mm) = 0.039 inch
1 centimeter (cm) = 0.393 inch
1 meter (m) = 3.281 feet
1 kilometer (km) = 0.621 mile
1 inch = 25.4 millimeters; 2.54 centimeters
1 mile = 1.609 kilometers
1 mile = 5,280 feet
PRESSURE
1 psi = 6.89 kPa
AREA
1 square meter = 10.764 square feet

INTRODUCTION
The Raven DCS 700 (DE-ICE CONTROL SYSTEM) is designed to improve the accuracy and
uniformity of granular and liquid material applications. Its performance relies on the
installation and preventive maintenance of the complete system. 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
DCS 700.
The DCS 700 consists of a computer based control console, speed sensor, hydraulic control
valves, liquid flow meter, granular rate sensor, and cables. The console mounts directly
in the cab of the vehicle for easy operator use. The speed sensor is installed in one
of several locations based on the style of the speed sensor used. The hydraulic valves
mount in the location available for ease of service and installation. The granular sensor
is either integral with the hydraulic motor or mounted to the auger/conveyer shaft.
Appropriate cabling is furnished for dealer/field installation.
The operator selects the desired application rate for a particular granular material
and the DCS 700 automatically maintains the desired rate regardless of vehicle speed.
The operator can also select granular with pre-wetting liquid and the DCS 700
automatically maintains the liquid volume to granular rate ratio regardless of vehicle
speed. A manual mode can be selected to allow the operator to manually control the
granular application rate. The desired application rate of the granular and liquid being
applied is displayed at all times during operation. The DCS 700 also displays additional
features such as vehicle speed, recent and annual material volume totals, and distance
traveled.

INSTALLATION
1. INSTALLATION OF DRIVE SHAFT SPEED SENSOR
1) Determine position for mounting of switch assembly and magnet assemblies. Choose
a location as near as possible to the drive shaft center hanger bearing, if so
equipped, or end of transmission. Mount bracket so that if it should loosen, the
sensor will not be damaged. The distance between the switch assembly and magnets
must remain between 1/4" and 1/2" regardless of load in truck box or severity of
terrain being negotiated. (See Figure 1).
2) Mount magnet assemblies on vehicle drive shaft so that magnets are equally spaced.
(See Figure 3). If drive shaft diameter is too large for clamps to reach each
other, use one of the small hose clamps included in the installation kit between
each magnet assembly.
4) Mount switch assembly to hanger bracket, cross-member, or bottom of truck box with
hardware provided. Position switch assembly so magnets pass across the center
of the molded switch assembly. (See Figure 4).
5) Clearance between magnets and switch assembly must be between 1/4" and 1/2".
(Adjust switch bracketry if required). Make sure magnets will not strike switch
assembly when vehicle is fully loaded.
6) Tighten switch assembly bracketry.
7) Secure cable with plastic cable ties. Route cable into vehicle cab as far away
as possible from engine alternator and voltage regulator.

3) On small diameter shafts, it may be
necessary to mount the magnet assem-
blies facing in opposite directions
and secure both clamps around shaft.
(See Figure 2).

2. MOUNTING FLOW METER
1) Mount Flow Meter in the area of the liquid control per Figure 5. All flow through
Flow Meter must go to pre-wetting nozzles only, i.e., no return line to tank or
pump after Flow Meter.
2) Flow must be in direction of arrow on Flow Meter.
NOTE: This is one example of a application schematic.
It is essential, when using suspensions, that the liquid system be thoroughly
rinsed out each day after use.
