Problem Cause Solution
Zero Flow in Bu/Hr or
lbs/Hr.. The cab, distribution,
or flow sensor cables
connection is bad, or
the flow sensor is
bad. Press MENU, DIAG and YIELD to check the the
Flow Offset.
The Flow Offset value should be between 300 and
400 and should never change while the separator is
running at full speed with or without grain flow.
If 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 Combine 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.
Bu/Ac or lbs/AcYield too
high or low. Average and
instantaneous yields
do not agree. See “Average and Instantaneous Yield Do Not
Agree” in this section.
You are not counting
the correct amount of
acres. Display AREA on the screen of the PFadvantage
to show the total acres. If they are incorrect for
the field or load, see “Incorrect Acre Counting” in
this section.
Bu/Ac or lbs/Ac Yield
too high or low (cont.) Weight in pounds is
inaccurate. See Incorrect Grain Weight (lbs) in this section.
