Seed Blockage Sensors
Setting the Sensitivity
Refer to the following table to set and adjust the sensitivity setting for each loop for a specific seeding
operation.
The best obstruction and blockage detection is achieved when the sensitivity is set as high as possible without
encountering a constant alert condition. To set the sensitivity for a specific seeding operation:
1. Ensure that the system is clear of obstructions.
2. Select and enter a sensitivity value from the table above and begin seeding. Ensure that the system
continues to display a normal operating condition at the initial setting.
Note:
If the seed blockage sensors consistently display a blockage alert, select a lower initial sensitivity
value before proceeding.
3. Increase the sensitivity until the seed blockage system indicates a blockage.
4. Decrease the sensitivity by 3 to 5 units at a time until the field computer no longer indicates blockage
conditions.
Note:
Do not decrease the sensitivity value below the initial value. Check the indicated sensor locations
and clear any obstructions and repeat the above procedure if the sensitivity value is decreased
below the initial setting.
