Pressure Sensor Simulator -
for meter air pressure simulation on YP planters
The Pressure Sensor Simulator (part # AE6691) can be connected to the planter harness
and used to send a simulated air pressure sensor signal back to the monitor system.

1. Locate the air pressure sensor in the air pressure assembly. On all planters, this is
mounted over the right wing.

Refer to Figure 12
Fig. 12
2. Disconnect the Voltage to Frequency Converter from the sensor, and connect the Pressure
Sensor Simulator to the converter. The red LED light with indicate the presence of power
in the harness.

3. Rotating the knob on the face of the simulator clockwise will cause the output signal to
increase in voltage. Turning the knob counter-clockwise will cause the output signal to
decrease in voltage. Harness and monitor setup can be verified by observing the pressure
reading displayed on the work screen, or on the channel 2 diagnostics screen. 8

5. Observe the workscreen or the channel two diagnostic screen at the channel frequency filter reading.
If no signal is seen, check monitor setup. Also check connections at the extension harness, and at
the FDBK 2 connection of the actuator harness.

4. To send a simulate pressure signal from the extension harness or at the FDBK 2 lead, refer to
page 4 and assemble the components listed in step one. Connect this assembly at either
location and test as you normally would.
