Before adjusting the sensors, verify the sensor arms are properly installed on the sensors.
•
Left Sensor (A): The
point
on the arm of the sensor should face
away
from the header. The point on the float
sensor arm (C) should be installed in the same direction, facing away from the header.
•
Right Sensor (B): The
point
on the arm of the sensor should face
away
from the header. The point on the float
sensor arm (D) should be installed in the same direction, facing away from the header.
To manually check the sensor
’
s output voltage range, follow these steps:
2.
Extend guard angle fully; the header angle indicator should be at
D
.
3.
Position the header 150 mm (6 in.) above the ground, and unlock the float.
