Figure 7.3: Float Indicator Box
Use a voltmeter to measure the voltage between Pin 1
(power) and Pin 2 (ground) wires at the AHHC sensor (A).
This will determine whether the combine has a 5 V system
or a 10 V system.
NOTE:
The combine key must be in the ON position, but the engine
does not need to be running.
The three possible voltage readings are as follows:
•
0 V
–
combine key is in OFF position, or there is a faulty
harness/bad connection
•
5 V
–
standard combine reading
•
10 V
–
10 V combine reading; adapter (MD #B6421) is
required
Manually Checking Voltage Range: One-Sensor System
The one-sensor system is standard for the FM100 Float Module. If equipped with the optional two-sensor system,
refer to
Manually Checking Voltage Range: Two-Sensor System, page 160 .
The output voltage range of the auto header height control (AHHC) sensors in some combines can be checked
from the cab. For instructions, refer to your combine operator
’
s manual or the AHHC instructions later in this
document.
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.
Figure 7.4: Down Stop Washer
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.
