  • Page 2 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.

  • Page 7: Introduction

    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.

  • Page 8: Installation

    INSTALLATION MOUNTING THE ENCODER Mount Encoder on output shaft of conveyor or other shaft which rotates at a known ratio to the conveyor. 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.

  • Page 9: Mounting The Flow Meter

    MOUNTING THE FLOW METER 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. Mount Flow Meter horizontal to the ground.

  • Page 10: Mounting The Control Valve

    MOUNTING THE CONTROL VALVE Mount the motorized Control Valve in the main hose line between the Flow Meter and the boom valve, with motor in the upright position. (For less than 3 GPM [11 lit/min], the motorized Control Valve is mounted in the by-pass line, refer to Appendix 1 for alternate plumbing diagram).

    CONSOLE CALIBRATION CALCULATING "METER CAL" The Flow Meter calibration number is stamped on the tag attached to each Flow Meter. This number is to be used for gallons [liters] per application. To convert original METER CAL from gallons to desired units of measure, see METER CAL CONVERSIONS on page 3.

  • Page 15: Calculating "Gran Cal

    CALCULATING "GRAN CAL" Factors which can affect the product GRAN CAL numbers are the product particle size, density, temperature, and humidity. Always calibrate the material you have purchased. Complete INITIAL CONSOLE PROGRAMMING, on page 15, before proceding with this procedure. The GRAN CAL value is derived using the following procedure: Place chalk mark or tape on granular belt shaft to use as a reference point.

  • Page 16: Verifying "Gran Cal

    VERIFYING "GRAN CAL" To verify this GRAN CAL number, perform the following procedure: Use a pre-weighed box to capture granules as they are metered out. Enter the pre-determined GRAN CAL into key labelled: Enter a "0" in key labelled: Turn granular belt ON to begin collecting granules. Turn granular belt OFF when GRAN TOTAL display reads 200.

  • Page 17: Calculating "Valve Cal

    CALCULATING "VALVE CAL" The initial Control Valve calibration number for VALVE CAL is 2123 for C-Sd (standard valve), or 743 for C-F (fast valve) and C-FC (fast close valve). The VALVE CAL number is used to control response time of the Motor Control to the change in vehicle speed.

  • Page 19: Initial Console Programming

    1. INITIAL CONSOLE PROGRAMMING When you first turn on Console power, after all installation procedures have been completed, the Console will display "US" in the display window. This means you must "calibrate" or program the Console before it can be operated. This is a one- time operation which does not have to be repeated.

    To verify maximum pressure and rate, enter 999.9 into LIQ CAL, 10 into METER CAL, 10 into GRAN CAL, and 1000 into SELF TEST. This assures that the motorized Control Valve is fully open. Verify maximum pressure and LIQ/GRAN rate. (Pressure gauge is not supplied with the DCS 300 system). NOTE: NOTE: NOTE: A pressure gauge MUST be installed to properly monitor the system.
