Setting up Reel Height Sensor
8.1
Checking and Adjusting Reel Height Sensor
The output voltage range of the auto reel height sensor can be checked from inside the combine or manually at the
sensor. For in-cab instructions, refer to the combine operator
’
s manual.
DANGER
To avoid bodily injury or death from unexpected start-up of machine, always stop engine and remove key
from ignition before leaving operator
’
s seat for any reason.
CAUTION
Check to be sure all bystanders have cleared the area.
IMPORTANT:
Ensure minimum reel height is properly set before adjusting reel height sensor. For instructions, refer to
Measuring and Adjusting Reel Clearance to Cutterbar, page 131
.
IMPORTANT:
To measure the output voltage of the reel height sensor, the combine engine needs to be running and supplying
power to the sensor. Always engage the combine parking brake and stay away from the reel.

NOTE:
For CLAAS combines: To avoid a collision of the reel with the cab, the machine is equipped with an automatic reel
height limitation. Some CLAAS combines have an automatic shutoff feature that engages when the automatic reel
height limitation is reached. When raising the header by more than 80 percent, the reel is automatically lowered.
The automatic lowering of the reel can be manually overridden, and a warning will appear on the CEBIS terminal.
To check the voltage range manually, follow these steps:
1.
Engage the combine parking brake.
2.
Start the engine and fully lower the reel.
