SPEED SENSOR SET UP
A speed sensor is required for the ROS device to perform speed based control system operations such as product
rate control, planter or seeder control, yield mapping, etc. Several options are available for speed sense and input.
Contact a local Raven dealer for additional information.
To configure the ROS device for the speed sensor connected to the system:
1. Touch the Edit icon in the Machine Panel to view the machine devices.
2. Locate and select the Speed Settings module. The Speed Settings tab will be displayed with the following
settings, displays, and options.
Sensor Type. Select the type of sensor currently used for speed signal with the control system.
Speed Cal. The speed calibration value is used to tune and adjust the control system to the connected speed
sensor. A calibration value may be entered for each sensor type to allow the operator to quickly switch between
speed sources if necessary without recalibrating the speed system during an active job.
The following calibration values are recommended for initial system set up:
These values are good starting points and generally yield adequate results, however, the speed cal should be
refined for the specific system and equipment. Refer to Appendix A, Calculating the Calibration Values for
instructions on refining the speed calibration.
NOTE: The GPS speed over CANbus feature is only available with specific Raven speed sense nodes. This
feature utilizes NMEA speed over ground data transmitted over the CAN network which eliminates
the need for a separate, external speed sensor.
Current Speed Display. The speed settings tab displays the current vehicle speed monitored by the selected
speed sensor.

NOTICE
When using the GPS speed over CANbus feature,
no refining or adjustment is available for the
speed cal value. Losing GPS signal for more than
a second will also result in loss of the CAN speed
signal which may affect product application in
progress.
