Series
Check sensor's output voltage range at float indicator according to the instructions that follow.

Checking Sensor's Output Voltage Range

The auto header height sensor output must be within a specific range for feature to work properly. To check
sensor's output voltage range, follow these steps:
1. Position header 150 mm (6 in.) above ground, and rest it on safety props. Unlock adapter float.
NOTE:
If header is not on down stops during next two steps, voltage may go out of range during operation causing a
malfunction of auto header height control (AHHC) system.
