Radar Simulator -
for ground speed simulation on air drills.
The Radar Simulator (part # AE6608) can be coupled with the Radar Sensor Adapter (part
# AE2609) and connected to the air cart harness to send a simulated speed pulse to the
monitor system.
Refer to Figure 13
1. Couple the Radar Simulator together with
the Radar Sensor Adapter.
2. Locate the hall effect or radar ground speed
sensor. On ADC2350/2350B carts, the sensor
is located inside the left wheel. On NTA607/
2007 drills the radar is located near the front of
the tongue. On NTA907/3007 drills, a rotary
application rate sensor is used for ground speed
and is located on the left hand ground drive
wheel.
3. Follow the lead coming out of the ground speed sensor until you find the three pin
weatherpack connector. Disconnect the sensor lead from the monitor harness and connect
the assembly made in step one to the monitor harness. On NTA607/2007 drills there is an
extension harness between the radar and the monitor harness. This assembly can also
be connected at the working set master harness on the lead labeled “GND SPEED”.
5. Rotating the knob on the face of the simulator changes the pulse rate that it outputs.
A clockwise rotation will speed the pulse rate up, and a counterclockwise rotation
slows the rate down.
4. Make sure the red LED light at the top of the simulator is brightly lit. This light
indicates a good power supply coming from the harness. If the light is off or dimly lit,
make sure the monitor system is powered on and inspect the harness and connections. 5

6. Observe the ground speed reading on the work screen or on the diagnostic screen at the
frequency digital groundspeed. If no signal is seen, check the ground speed setup in the
monitor. Also check the connection at the ground speed connection at the actuator harness.
