Controller Functions

The controller is located on the drill. The controller forms the link between the separate sensors, actuators, and monitor.

A monitor located in the cab displays data from the controller and allows user input to the controller.

A microprocessor in the controller processes the user entered data and the signals transmitted by the sensors. The processed information is converted into:

A. CONTROL SIGNALS: Signals sent from the controller to operate the actuators.

• Automatic tramline operation.
• Seed meter shutoff.

B. ALARM SIGNALS: Signals sent to the controller from the sensors that indicate malfunctions in the monitored system.

• Low fan speed alarm.
• Low hopper alarm.
• Meter operation sensors.

C. DISPLAY SIGNALS: Signals sent from the controller to the monitor that displays the following information.

• Operational status.
• Tramline pattern.
• Area covered in current field.
• Total area covered.
• Area worked per hour.
• Work speed.
• Hours operated.
• Actual fan speed.
• Hopper content.
• Obstruction in seed delivery system.
• Meter status.
