Incorrect
Temperature
Reading 1. The temperature offset has been set to a large negative or positive
number (it should be between -15 to 15 T OFFSET)
Solution: Press the MOIST key until “xx T OFFSET” appears on the
display to check the value of T Offset. If the offset number looks
incorrect, calibrate for temperature again
2. The cable connections are bad.
Solution: Disconnect the cab, distribution, and moisture sensor cables
and inspect the pins for corrosion. Examine the cables for cuts or
pinches. Reconnect the cables and look at the temperature again.
Area Count Light
Always On The area count light must be off to count acres.
1. The area count switch is in the down position.
Solution: The area count switch must be in the up position to enable the
area count light to turn off when the head is lowered. If the area count
switch is in the down position, the area count light will always be on.
2. The stop height number is set too high.
Solution: Press the STOP HEIGHT key and use the top-right DOWN
ARROW key to decrease the stop height number so that when the head
is raised the light turns off (a typical range is 50 to 80).
3. The header sensor is installed backwards.
Solution: Refer to the installation instructions and ensure the header
sensor is installed in the correct place with the correct orientation (cable
pointing towards the rear of combine, open end of the black header
sensor bracket pointing towards the ground).
4. The cable connections are bad.
Solution: Disconnect the header sensor, distribution, and cab cables.
Examine the pins for corrosion and reconnect the cables. Check the
cables for places where they may have been pinched or cut. Check each
cable for continuity and shorts with a volt-ohm meter. Refer to the
Reference section for the correct pinouts.
5. The header sensor is bad.
Solution: Check the resistances of the header sensor between pins A, B,
and C on the header sensor cable. Refer to the Reference section for the
correct resistance readings.
