MacDon FlexDraper FD75 - Sensor Output Voltage Range - Combine Requirements

214323 134 Revision B
4.4 Sensor Output Voltage Range – Combine Requirements
The auto header height control (AHHC) sensor output must be within a specific voltage range for each combine, or the
AHHC feature will not work properly.

NOTE:
Some combine models do not support checking sensor output voltage from cab (early 23/2588 series, CLAAS 500/700
series). For these models, check output voltage manually. For instructions, refer to 4.4.1 Manually Checking Voltage
Range, page 135.
