SERVICE MANUAL

N O T I C E
The use of the suspension type fertilizers and lime 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 300 (DE-ICE CONTROL SYSTEM) is designed to improve the uniformity of pre-
wetting applications automatically. 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 system.
The DCS 300 consists of a computer based Control Console, a Granular Encoder, 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 Granular Encoder is mounted on a granular
belt shaft. The motorized Control Valve and Flow Meter mount directly to the framework
of the spreader truck. Appropriate cabling is furnished for field installation.
The operator sets the target rate (volume per granular ton) to be applied and the DCS
300 automatically maintains the pre-wetting flow according to the actual granular
application rate (within range of selected spray nozzles). The DCS 300 additionally
functions as a volume totalizer and granular totalizer (up to 10,000 kg or lbs).

INSTALLATION
1. MOUNTING THE ENCODER
1)1)
1)1)
1) Mount Encoder on output shaft of conveyor or other shaft which rotates at a known
ratio to the conveyor.
2)2)
2)2)
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)3)
3)3)
3) Install mounting tabs to Encoder as shown in Figure 1. Connect mounting tab to
mounting bracket (not provided) to prevent Encoder from rotating. DO NOTDO NOT

2. MOUNTING THE FLOW METER
l)l)
l)l)
l) Mount the Flow Meter in the area of the boom valve per Figure 2. All flow through
the Flow Meter must go to the boom valve only, i.e. no return line to tank or pump
after Flow Meter.
2)2)
2)2)
2) Mount Flow Meter horizontal to the ground. Use the bracket to secure the Flow
Meter.
3)3)
3)3)
3) For best results, allow a minimum of 7 1/2 inches [20cm] of straight hose on inlet
of Flow Meter. Bend radius of hose on outlet of Flow Meter should be gradual.
4)4)
4)4)
4) Flow must be in direction of ARROW on Flow Meter.
NOTE:NOTE:
NOTE:NOTE:
NOTE: For flow rates less than 3 GPM [11 lit/min], mount the Flow Meter
vertically with arrow pointing upward. (Refer to Appendix 1 for
alternate plumbing diagram).
NOTE:NOTE:
NOTE:NOTE:
NOTE: It is essential, when using suspensions, that the system be thoroughly
rinsed out each day after use. Failure to do so may cause system to
malfunction.
