7500 Seed Rate Controller
7500 SEED RATE CONTROLLER
OVERVIEW
The Farmscan Seed Rate controller 7500 was developed to provide advanced seed rate control capabilities
whilst maintaining an extremely simple Tile & Tab user interface.
The controller has a variety of selectable display and control options that can be configured to suit a
specific application or user preference. The controller options and calibration setup can also be locked to
limit operator access.
The optional switch box controller incorporates 6 Bin/Tank control switches, master on/ off control and
up/ down rate control.
The 7500 can control hydraulic, electric drive or linear actuators.
A large colour LCD (Liquid Crystal Display) touch screen provides all the information required to operate
the device in one view including direct readouts for rate, speed, tank level, trip area, trip volume, time and
pressure (optional when used with liquid). Special icons indicate active control options.
Seed records are maintained for virtually an unlimited number of paddocks (memory dependent) in the
Jobs screen and may be exported in CSV format via USB to a Windows or Apple-based record keeping
program.
The controller may be operated in automatic, manual or GPS (Slave/ Task) mode - variable rate map (VRC
control via Shape File). In Automatic and Slave mode, the control drive responds automatically to speed to
maintain the target rate. Manual increment and decrement of the target rate is also possible.
In Slave/ Task mode, the controller will accept rate commands from a separate guidance/ task computer
linked to GPS and simultaneously report back on rate applied for the purpose of rate mapping and
verification of seeded area. (NB. Some of these features are still under development)
In the event of an error, an audible warning alerts the operator by displaying a red tile (assuming that this
function has been selected on the display) text on a tab which can then be selected to explain the fault.
The 7500 terminal is connected via CANbus to provide drive control and sensor feedback
A standard wheel sensor can be supplied for ground speed pickup or a radar speed sensor may be
connected using the inbuilt radar interface. Alternatively, a GPS can be used to provide ground speed.
