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.

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.
FIGURE 1
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).

NOTE: Distance A and B must be equal.

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.

3. MOUNTING GRANULAR ENCODER
1) Mount Encoder on output shaft of conveyor or other shaft which rotates at a known
ratio to the conveyor.
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 6. 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.

4. MOUNTING LIQUID AND GRANULAR CONTROL VALVES
The mounting of the liquid and granular Control Valves are based on the type of
pre-wet and hydraulic system of the truck.
5. MOUNTING CONSOLE AND CABLING
NOTE: For instructions on mounting custom cabling, hydraulic valves, and
liquid control systems, consult your dealer.
l) Mount the Console to a secure support inside the cab of the vehicle without
hindering the visibility of the operator.
2) Connect the Console Control Cable to the plugs in the back of the Console. (See
Figure 7).
FIGURE 7
3) Turn POWER switch to OFF and route the Red wire to the +12 volt fuse block and
White wire to the negative connection. (DO NOT CONNECT WIRES TO THE STARTER).
Secure the wires with plastic cable ties.
4) Connect the Speed Sensor Cable to the plug in the back of the Console.
5) Verify connector "A" has plug installed and "B" is connected to "C".

1. INITIAL CONSOLE PROGRAMMING
Verify MASTER switch is OFF. After all installation procedures have been
completed, turn POWER switch to GRAN, the Console will flash "CAL" in the GRAN
and LIQ displays. This means that the Console must be "programed" before it
can be operated. This is a one-time operation which does not have to be
repeated. Turning OFF the POWER Switch or disconnecting power to the Console
does not affect the Console memory. All data is retained in nonvolatile
memory.
NOTE: The KEY switch must be in and turned to the horizontal position to enter
data into the Console. This is referred to as the "programming mode".
Only the following keys are an exception: . A
"0" (zero) may be entered for "day distances", "day granular volumes",
"day liquid volume". Refer to 'Distance and Volume Displays' on page
22 for procedure.
IMPORTANT: If an entry selection error is made during Steps 1-3, place the POWER
switch to OFF. Place KEY switch to the horizontal position. Depress
and hold while placing the POWER switch to GRAN. This will "reset"
the Console. The GRAN and LIQ displays will flash "CAL" and DATA display
will show "US".
The following steps must be followed for proper calibration:
1) Selecting US (lbs/mile), or SI (Kg/km).
a) To select US or SI, depress until the desired selection is
displayed in the DATA display.
b) Momentarily depress , the DATA display will now display SP1.
2) Selecting SP1 (drive shaft, wheel drive, etc.), SP2 (radar), or SP3
(transmission).
a) To select SP1, SP2, or SP3 depress until desired selection is
displayed.
b) Momentarily depress , the DATA display will now display 2-P.
3) Selecting Pre-wet Control Valve type 2-P (pulse width modulated-hydraulic or
booster amp-electric) or 2-Sd (standard/motor control).
a) To select 2-P or 2-Sd, depress until desired code is displayed.

12
b) Momentarily depress , the DATA display will now display "0".
c) Depress and hold . The previous 3 settings that were selected will
be displayed in the DATA display. Verify the selections made are correct
before proceeding to the next step. If an error is noted, place POWER switch
OFF, depress and hold , place POWER switch to GRAN, and repeat steps
1-3.
NOTE: For the remainder of the Console programming the and keys
will be used advance through the various selections.
