Blockage Monitoring Sensors
Communication Error Information. If a communication issue is encountered on either sensor loop, the
status screen will display the value of the of the last sensor which the system is currently able to detect on
the sensor loop. For example, “Loop 2 Sensor 8” means that sensor 8 on loop 2 is currently communicating
correctly. This information may be useful to address communication problems.
Blockage Monitor Setup Icon. Touch the setup icon to go to the Blockage Monitor Setup screen if necessary
during a field operation to adjust loop sensitivity or alarm settings. Refer to the Configuring Blockage
Sensor Loops section on page 224 for details on using the Blockage Monitor Setup screen.
Pause Status Updates Icon. The blockage system updates the status screen continuously during field
operations. Use the pause screen updates icon to ignore status screen updates and to allow the operator to
address multiple blockage conditions or to review blockage information for momentary blockages detected
during field operations.
Note:
The pause icon only pauses updates to the blockage monitor screen. Additional blockage alerts
will still be received by the field computer and product control features will be unaffected.
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 field operation:
1.
Ensure that the system is clear of obstructions.
2.
Select and enter a sensitivity value from the table above and begin operation. 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.
