Actuator Test Box - For Air-Pro Planters.
The Actuator Test Box (part # AE6690) can be used to troubleshoot the split air actuator and as an
aid in the replacement of it if needed. The planter harness must be electrically connected to the
tractor for the switch box to function. If this is not possible, another 12VDC power supply needs
to be connected to the tower connector of the test box harness (connector with only two wires). Pin
Refer to Figure 2
1. Locate the rotary actuator on the side of the spit air valve.
1
The spit air valve is always mounted directly next to the fan.
Refer to Figure 3
2. Follow the wiring harness that comes out of the rotary
actuator until the 6 pin weatherpack connector is found.

Disconnect the actuator harness from the extension harness
at this location, and connect the two leads of the test box

Fig. 2
3. The Actuator Test Box contains a spring centered momentary
switch. Moving the switch to one side or the other will cause
the actuator to rotate either clockwise or counterclockwise.
When the switch is released, it will re-center itself and stop actuator
motion. DO NOT USE THIS TOOL AS A REPLACEMENT
FOR AIR PRESSURE CONTROL DURING PLANTING!
Using the Actuator Test Box for actuator replacement.
Fig. 3
Refer to Figure 4
1. The rotary actuator is mounted in slots to allow for adjustment to
the assembly. Leave the mounting hardware loose until final
adjustment is made.
2. Connect the test box as described above in step 2.
3. Using the test box, electrically rotate the actuator fully clockwise. (As viewed
looking at the arrow on the face of the actuator.)
4. Remove the top meter pressure delivery hose closest to the actuator and
visually inspect the location of the split air vane. Adjust the actuator until
the edge of the vane is flush with the bottom of the seed delivery outlet.

1
5. Tighten the mounting hardware and use the test box to operate the valve
through its entire range of travel to ensure there is no physical interference.
Notes - The rotary actuator contains internal limit switches that are set to hold its rotation within a 60 degree range.
When either switch is tripped, the actuator will stop and can only move back in the opposite direction.
- An internal circuit breaker will cut power to the actuator if it encounters a high amp load. If the actuator will
not move, check for +12VDC in pin A of the 6 pin connector using pin B for the ground. If the voltage is
present but there is no visible LED light in the window of the actuator, unplug it, wait 20 seconds and
reconnect it. This will reset the breaker.

A clockwise rotation will speed the pulse rate up, and a counterclockwise rotation
slows the rate down.
6. Observe the ground speed reading on the work screen or on the diagnostic screen at the

Also check the connection at the ground speed connection at the actuator harness.

Sensor Tester - for testing ground speed sensors on NTA3007/907.
The Sensor Tester (part # AE6602) can be used in conjunction with the Application Rate
Sensor Adapter (part # AE2607) to verify the operation of the ground speed sensor on
NTA3007/907 air drills.
Refer to Figure 20
1. Assemble the Seed Sensor Tester together with the
Application Rate Sensor Tester Adapter.

2. Locate the wiring harness coming out of the ground speed
sensor. On NTA3007/907 drills, this can be found on the

end of the small ground drive wheel on the left hand side.
Follow the lead until you find the three pin connection at
the working set master harness.
Fig. 20
3. Disconnect the sensor lead from the harness and connect the assembly
made in step one to the sensor.
4. This ground speed sensor will create 360 pulses per revolution of its input shaft. Every
pulse created will case the sensor tester to “beep” if the sensor is functioning properly.
Note: The Seed Tube Sensor Tester operates on a 9 volt battery that is accessible through a door
in the back of the case. Make sure the battery is good before replacing a sensor.
Sensor Tester - for testing fan speed sensors on air drills.
The Sensor Tester (part # AE6602) can be used in conjunction with the Application Rate Sensor
Adapter (part # AE2607) to verify the operation of the hall effect fan speed sensor.
Refer to Figure 21
1. Assemble the Sensor Tester together with the
Application Rate Sensor Adapter.
2. Locate the hall effect sensor the supplies the fan speed

signal to the monitoring system. This will be the wiring
harness coming out of the screen on the fan assembly.
Fig. 21
3. Follow the harness until it connect to the monitor harness. Disconnect the harness and
connect the assembly made in step one to the sensor lead.
4. If the sensor is still mounted in the fan assembly, any motion of the fan should cause the
sensor to create a pulse that will make the tester “beep”. If the sensor has been removed,
waving a metallic object like a screwdriver should produce the same result.
Note: The Seed Tube Sensor Tester operates on a 9 volt battery that is accessible through a door
in the back of the case. Make sure the battery is good before replacing a sensor.
