PF3000 Troubleshooting
Ag Leader Technology Harvest Mode
April 2002 6-9
Problem Cause Solution
Incorrect Moisture
NOTE: There must be
grain flow to have a
moisture reading,
otherwise the reading will
always be 5 percent. Moisture has not been
calibrated or the
calibration is
incorrect. See “Calibrating Moisture” in the Calibration
Section.
Press MENU, CAL, MOISTURE, and ENTER
MOISTURE to display moisture calibration. The
Moisture Offset is normally between –8% and
+8%. If the offset is not between these values
calibrate moisture again.
If you have calibrated the moisture at very high
moistures (28% to 35%) and now are harvesting at
lower moistures, it may be difficult to find a
calibration offset number that is exactly correct for
both ranges of moisture. You should either choose
a calibration offset number that is close for both
ranges of moisture or set all the high moisture
loads to a separate grain type and enter a new
calibration offset number for that grain type.
Moisture Readings of
5% or Erratic. Bad connection or
damaged moisture
cable. Check temperature reading. If it is –20 degrees
there is a bad connection or cable damage.
Check moisture sensor cable where it connects at
the distribution cable and cab cable. Look for pins
that have corrosion or any part of the cable that has
nicks or may have been pinched.
Moisture is too high or
too low. Temperature
calibration has not
been performed. See Calibrating Temperature in the Calibration
Section.
NOTE: If the temperature calibration was
incorrect and you correct it, check the moisture
calibration again.
Moisture readings are
high. Moisture sensor or
auger tube has an
accumulated sticky
buildup. Clean any buildup from the sensor blade and
auger.
If buildup is so severe that the moisture sensor will
not stay clean adjust the moisture setting manually.
See “Moisture Setting” in the Operation Section.
