Troubleshooting
Problem Causes Solutions
No material flow - all
rows
Empty hopper Load material.
Meter in use clogged Clean-out meter (page 75).
Fan not operating Check hydraulic and electrical connections
for fan.
Fan speed too low Check pulses-per-rev setting for fan in the
monitor. Increase fan speed to
recommended range. See monitor manual.
Fan running backward Reverse fan circuit hoses at hitch.
No material flow -
multiple rows
Primary seed hose blocked Check seed hoses for kinks, congealed
materials at low spots, nests, and pests.
Tower inlet or turret blocked Clear blockage.
No material flow - one
or two rows
Seed tube blocked at row Inspect and clear seed tube.
Tower port blocked for affected row Disassemble distribution ring and clear
blockage.
False alarm - blockage sensor disconnected
or failed Run terminal self-test. Swap sensor with a
working row to verify failure. Replace
sensor.
Material is flowing, but
is not detected by
monitor
This is normal during the first few meters of
planting, as it takes some time for material
to reach rows. Lower openers 3m before planting is to
begin. Monitor does not check for blockage
during first 5 seconds.
Lift switch not adjusted correctly, failed, or
not wired correctly. Check, adjust or replace switch (page 77).
Monitor disconnected at hitch Connect monitor.
Planting too little -
some rows
Partial blockage in meter chamber, seed
hoses, towers, seed tubes Treat as blockage. See “ No material flow -
multiple rows ” and “ No material flow - one
or two rows ”.
Planting too little - all
rows
Incorrect seed rate, meter flutes, or rate
range setting. Check seed rate information beginning on
page 44.
Air system leaks slowing material flow above
meters Check hopper lids, meter seals, manifold
caps and seed hose connections. Adjust
latch and/or replace seals as needed.
Seed size and weight or fertilizer density
and granularity vary. Calibrate. Adjust rate to compensate.
Seed or fertilizer density and granularity
may vary from season to season, batch to
batch, and between different suppliers. Calibrate again if materials might have
changed since last calibration.
Low material level in hopper Fill hopper.
Fan speed too low Increase fan speed (page 40).
Fan will not run fast enough Tractor must be able to supply 68 liters/min
at 14 bar.
Fan will not run fast enough Check that hydraulic fan check valve is not
installed backward.
