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.

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.
