Radar Simulator -
for ground speed simulation on YP planters.
The Radar Simulator (part # AE6608) can be connected to the planter harness and used to
send a simulated speed pulse to the monitor system.
Refer to Figure 5
1. Locate the radar or hall effect sensor that supplies the speed signal to the monitoring
system. On YP12 and YP16 planters, the hall effect sensor is located inside the left
rear wheel. On all others, the radar sensor will be located under and in front of the
seed hopper or hoppers.
3. Disconnect the sensor lead at this connection and connect the radar simulator in its place.
2. Follow the wiring harness out of the sensor until the connection at the Working Set Master
harness is found.
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.

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.
