Configuring Blockage Sensor Loops
Each sensor loop may be configured individually to allow the system to accurately monitor the status of
separate delivery systems (e.g. seed or product tubes) and alert the operator to obstructions in either delivery
system. To properly monitor the seed or product delivery system, the field computer must be configured for the
number of blockage sensors installed in each section of the implement.
1.
Review the Offsets and Implement Type Selection section on page 142 to configure the implement.
2.
After the implement is correctly configured, select the Blockage icon from the System menu. The
Blockage Monitor Setup screen will be displayed on the field computer.
The following information is displayed at the bottom of the Blockage Monitor Setup screen:
•
Currently configured sensor counts for each configured sensor loop. The field computer must be
programmed for the number of sensors in each loop. This value does not change when sensors are added
or removed from the blockage monitoring system.
•
Enable options for sensor loop 1 and 2.
•
Enable option for the audible alarm feature for the blockage monitor.
Section Assignments. The Section Assignments button allows the operator to configure the sensor loops
connected to the control for each implement section. Refer to the Configure Sensor Loops section on
page 225 information on the sensor section setup procedure.
Alarm Delay. The alarm delay setting allows the operator to set a delay between when the system detects a
blockage and when the alarm features are activated on the field computer. Use this setting to avoid
displaying errors during field operations if the control system intermittently encounters momentary
stoppages in product or seed flow.
Loop Sensitivity. Use the sensitivity value to set the approximate number of seeds per second which each
sensor in the loop should detect when the system is operating normally. If a sensor does not detect the set
value for seeding rates, the system will display a blockage or obstruction and indicate which sensor is
detecting the error. The default sensitivity value is 15.
Refer to the Setting the Sensitivity section on page 227 for more information on setting and adjusting the
sensitivity value for each sensor loop.
