Radar Simulator -
for fan speed simulation on air drills
The Radar Simulator (part # AE6608) can be coupled with the Application Rate Sensor
Adapter (part # AE2607) and the Radar Sensor Adapter (part # AE2609) and connected to the
air drill harness for sending a simulated fan speed pulse to the monitor system.
Refer to Figure 14
1. Assemble the Radar Simulator together with the Radar Sensor Adapter and the
Application Rate Sensor Adapter.
2. Locate the wiring harness coming out of the fan speed sensor and follow it until you find
the connection at the extension harness.
3. Disconnect the sensor lead from the extension harness and connect the assembly made in
step one. It can also be connected to the RPM sensor lead where the extension
harness connects to the working set master harness.
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. Rotating the knob on the face of the simulator changes the pulse rate that in outputs.
A clockwise rotation will speed the pulse rate up, and a counterclockwise rotation
slows the rate down.

6. Observe the fan rpm reading on the work screen or on the diagnostic screen at the frequency
rpm reading. If no signal is seen, check fan rpm setup in the monitor. Also check the
extension harness and the RPM connection on the actuator harness.
