    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.

  • Page 8: Installation

    INSTALLATION 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.
