1.0 INTRODUCTION
The SEED HAWK Drill Monitor is capable of monitoring and displaying:
x ground speed (Radar or Implemented Mounted Smart Shaft Sensor)
x two fans
x three shaft speeds
x three bins
x field area
x total area
x sounding an alarm and displaying which of the devices listed above are at fault.
x three application rates
The monitor will sound an alarm to alert the operator if it detects any of the following
conditions:
x low shaft speed on any shaft
x low level in any bin
x loss of motion
x low or high fan speed
The monitor allows the following settings to be changed:
x Ground speed pulses per 400 feet and pulses per revolution
x Pulses per revolution of 3 shafts
x Low shaft alarm point for 3 shafts
x Low bin alarm point for 3 bins
x The width of the implement
x Display in imperial or metric units
x Low and High fan alarm point for 2 fans
These settings, as well as the field and accumulated areas are stored in non-volatile memory.
This means that the information is retained even when power is disconnected.
The SEED HAWK drill monitor utilises a multiplexed data communication system to monitor the
functions of a drill. In the multiplexed system, all sensors communicate with the monitor on the
same three wires. This permits a reduction in wiring cost and complexity as well as a reduced
connector count.
The monitor is packaged in a black ABS plastic case. Three cables exit the rear. One is a two
wire power cable that connects to the tractor power supply. The second is a three wire cable
that brings power and communications to the remote sensors through the main harness. The
third is a four wire cable for the optional radar ground speed sensor.
