Problem Cause Solution
Incorrect Grain Weight
(lbs) Calibration numbers
C1 through C11 are
set incorrectly. Press MENU, CAL and WEIGHT key. Press
SHOW CAL NUMBERS to display calibration
numbers C1 through C11. If any of the C2
through C11 calibration numbers are set to zero,
select that C value and press EDIT key. Use
up/down arrow keys to set the values on the
calibration sheet for that grain type, then press
ACCEPT key. Calibrate the monitor for grain
weight. The C numbers will set automatically to
their correct value.
Calibration loads are
set on the wrong
grain type. See “Calibrating Grain Weight” in Calibration
Section.
The result of
increased or
decreased in speed,
harvesting a higher or
lower yield, or grain
moisture greatly
changes. Weigh and enter one or two calibration loads for
different field conditions.
If monitor hasn’t calibrated accurately after 10 to
12 loads at different grain flow rates, call Tech
Support 515-232-5363.
Clean grain elevator
has excessive paddle
tip clearance at the
top. Paddle clearance must be ½ in. or less.
If more than ½ in. adjust the top shaft of the
elevator and recalibrate by eliminating the actual
weights and entering new ones or changing grain
types and entering new actual weights.
Incorrect Temperature
Reading Temperature offset
had been set to a
large negative or
positive number. Press MENU, DIAG and YEILD to display
temperature calibration number (Temperature
Offset). If this number is not between –15% to
+15% calibrate temperature and recheck moisture
calibration.
Cable connections are
bad. Disconnect cab, distribution and moisture sensor
cables and inspect pins for corrosion. Inspect the
cables for cuts or pinches. Reconnect cables and
check temperature again.
