Additional controller setup
You can also set additional features on variable rate controllers, including:
l Coverage mapping (page 265)
l Target and applied rates (page 265)
l Units (page 266)
l Alarms (page 265)
Alarms
If you want low limit and target rate alarms, set these on the variable rate controller. You can also
set a default rate to be used if you go off the prescription or do not have a prescription. For more
information, refer to the documentation provided with your variable rate controller.
Coverage mapping
The FM-1000 integrated display receives the applied rate and can also receive the number of active
boom sections from a variable rate controller. It does not receive any information about the swath
or application width.
To accurately record coverage maps, if your controller does not send the number of active boom
sections, set the application width to match the agricultural equipment that you are using (for
example, the width of the spray boom).
Prescriptions
You can define variable rate controller setup data, and load prescription files that define the rates to
be applied in different areas of the field. This information is used to send target rates to the variable
rate controller. Applied rates are received from the controller, and both target and applied rates are
shown on the screen. In addition, data relating to the variable rate application may be logged to the
card.
The information describing prescriptions for the Field-IQ system also applies to non-Trimble variable
rate controllers.
Target and applied rates
The FM-1000 integrated display can control only a single channel at any one time. This active
channel is specified in the Edit Variable Rate Controller settings screen. The target and applied rates
shown on the Run screen are specific to this active channel.
