PF3000 Troubleshooting
Ag Leader Technology Harvest Mode
April 2002 6-7
Problem Cause Solution
Zero Flow in Bu/Ac or
lbs/Ac (cont.). Calibration number
set to zero 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.
The cab, distribution,
or flow sensor cables
connection is bad, or
the flow sensor is
bad. Press MENU, DIAG and YEILD to check the
Min/Max values and the Flow Offset. The Min
value should be between 40 and 200, the Max
value should be between 150 and 600.The
Min/Max values may change. The Flow Offset
value should be between 300 and 400 and should
never change while the separator is running at full
speed with no grain or with a grain flow. If the
Min/Max value is incorrect (e.g. Min=255,
Max=0), or the Flow Offset number is incorrect,
check the cab, distribution and flow sensor cable
for loose connections or cable damage. Use a volt-
ohm meter to check for the correct resistance
readings. See “Checking Flow Sensor
Connection” in the Reference Section for the
correct resistance readings.
The grain is not
hitting the flow
sensor because the
flow sensor or
stainless steel
deflector plate is
installed backwards See your PF3000 installation instructions to ensure
flow sensor and deflector plate are installed
correctly.
Grain flow is too low
for the monitor to
measure consistently. This is a problem where flow of grain is small (1
to 2 lbs/sec, for example grass seed). If possible
take a larger swath or drive faster during harvest.
If this does not resolve the problem, call Tech
Support (515-232-5363) for further support.
