Theory of Operation
A review of the following points will help the service technician to understand the complete system which
will help diagnosing specic problems.
1. Each sensor returns a variable voltage depending on header height.
• High header height = high voltage (approximately 4 volts)
• Low header height = low voltage (approximately 1 volt)
2. Each sensor has 3 wires:
• A: blue = ground
• B: white = signal returned to combine (varies1-4 volts)
• C: pink = 5 volt power
3. The Insight box adjusts signals as needed then sends them to combine using the same combine
wiring as OEM system would use.
• All sensors are scaled to an appropriate range for combine
• Insight will reverse the direction of swing if needed
• Insight box reads all sensors and sends signals to combine that will cause appropriate height and
or tilt response
• If Foresight is enabled - the Insight box magnies the voltage change below the point where the
snout tips touch the ground
4. The voltages the combine sees are exactly like what it would see with an OEM system. All existing
combine controls and settings may be used.
Basic Requirements
Each sensor must meet basic requirements for the combine to accept the calibration. If any sensor does
not meet the requirements below you must correct it (to meet the requirements) and then recalibrate the
Insight box. See the header manual for sensor adjustment instructions.
• Sensor output voltage must always be between .3 and 4.7 volts.
• Sensor output voltage must change more than 1.0 volts from raised to lowered position for each
sensor.
