The automatic auger swing system is time based:
- Pressing the auger swing out switch will cause the auger to swing out for a certain amount of time.
- Pressing the auger swing in switch will cause the auger to swing in for a certain amount of time.
Since there is not a sensor on the unloading auger which can be used to determine where the auger is, the electronic control of the auger will "keep track" of where the unloading auger is, based on the amount of time it has been swinging in or swinging out.
Because unloading auger on different machines may take longer or shorter to swing to the home position or swing to the fully extended position, the electronic control may not be able to accurately know where the auger is at all of the time. Eventually, the electronic control may "lose track" of where the unloading auger is. Because of this, the auger may sometimes not return fully to the home position, or may not extend fully when the automatic swing switches are pressed.
This can also effect the unloading auger drive engagement, since the unloading auger drive will not engage electrically unless the auger is at least 50% swung out. If the electronic control "loses track" of the position of the auger, at times the auger may be fully extended but the unloading auger drive will not stay engaged. This is because the electronic control is not accurately tracking the auger position and believes the auger is less than 50% swung out.

If the unloading auger experiences any of the above problems the customer can "zero" the unloading auger position by performing the following procedure:
1.
Using the auger swing out button, extend the unloading auger fully.
|
2.
Press the unloading auger swing in AUTOMATIC button (the second detent) and release. Let the auger swing in until it comes to a stop.
3.
If the auger stops short of the home position, press and hold the auger swing in button until the auger is fully in the home position.
This will reset the logic for the location of the unloading auger in the event that the electronic control "loses track" of the position of the auger.
However, if the problem reoccurs, the auger swing time settings in diagnostics may need to be calibrated.
NOTE:
Refer to "Machine Setting Procedure" in this section to access and modify the relevant control unit diagnostic address required for this calibration.
Prepare the combine for calibration:
Engine must be running at high idle.
Return the auger to the "home" position.
Calibrate the auger swing out and swing in time:
1.
Using a stop watch, record the amount of time it takes to manually swing the unloading auger from home to the fully extended position.
2.
Change Left Control Unit diagnostic address
E03 100
(Auger Swing Out Time) for the time you recorded.
The table below shows what value the address should be set to based on the time you recorded.
3.
Using a stop watch, now record the time it takes to swing the auger from the fully extended position to the home position. This will typically take 2-5 seconds longer than it takes to swing out.
