Yield in Bu/Ac or lbs/Ac
is Always Zero Zero flow in bu/hr. Push Display Selections key, push the right/left
Menu Selection keys until GRAIN FLOW is
displayed and push key. If the value is zero or
erratic, refer to “Elevator Speed is Zero or Erratic”
in this section
Acres are not being
counted. Push Display Selection key, push right/left Menu
Selection key until AREA is displayed and push

Zero Flow in Bu/Hr or
lbs/Hr. Elevator speed is zero
or erratic. NOTE:
Elevator speed must
be between 250 rpm
and 600 rpm or there
will be 0 flow in
bu/hr. Push Display Selection key, push the right/left
Menu Selection key until ELEVATOR SPEED is

The clean grain
elevator has
excessive paddle tip
clearance at the top. Check paddle clearance between the tip of paddle
and inside of the clean grain elevator housing as
paddles rotate around the top sprocket. If
clearance is more than ½ in. (1/2 in. or less id
ideal) readjust the top shaft of the elevator and
recalibrate. Change grain types and enter new
loads and calibrate weight again.
The C1 number
(vibration calibration
number) is too high
and eliminating
pounds of grain. Press MENU, CAL and WEIGHT key. Press
SHOW CAL NUMBERS to display C1 through
C11 (C1 is vibration). If any of the C2 through
C11 numbers are set to zero, select that C value
and press EDIT key. Use the up/down arrow keys
to set them to the values on the initial calibration
sheet for that grain type. Press ACCEPT key.
Calibrate the monitor for grain weight and the C
numbers will automatically be set to their correct
value for your combine.
