Manually Checking Voltage Range: Two-Sensor System
FM100 Float Modules equipped with the optional two-sensor system have a left and right sensor located on the
back frame of the float module.
To manually check the sensor's output voltage range, follow these steps:
1. Extend guard angle fully; the header angle indicator should be at D.
2. Position the header 150 mm (6 in.) above the ground, and unlock the float.
3. Check that float lock linkage is on down stops
(washer [A] cannot be moved) at both locations.
NOTE:
If the header is not on down stops during the next two
steps, the voltage may go out of range during operation
causing a malfunction of the AHHC system.
4. Adjust the cable take-up bracket (B) (if necessary) until
the pointer (A) on the float indicator is on 0.
