20 / TROUBLESHOOTING GUIDE
1. Swap the sensor with another row or hopper. If problem moves, sensor
is faulty. Otherwise, harness or module is faulty.
2. Check module harness connections at the module and sensors. Check
module harness for pinches, worn, or broken elements. Check sensor
cables for pinched, worn, or broken elements.
3. Check module harness for pinched, worn, or broken elements. Check
sensor for pinched, worn, or broken wires.
ROWS FAIL THAT ARE CORRECTLY PLANTING.
SELF-TEST INDICATED THE SENSOR WAS
PRESENT.
Probable Cause
1. Minimum seeding rate set too high
2. Defective seed sensor
3. Poor harness connection at console or at sensor that is intermittent
4. Defective sensor or harness wire that is intermittent
5. Defective harness or sensor cable (signal shorted or power open)
6. Hopper sensor is plugged into seed input
Corrective Action
1. Lower the minimum seeding rate (left hand +/- switch).
2. Clean sensing elements using a dry bottle brush. Some seed
treatments require scrubbing with water and a commercial cleanser.
3. Check module harness connections at the module and sensors. Check
module harness for pinched, worn, or broken elements. Check sensor
cables for pinched, worn, or broken elements.
4. Swap the sensor with another row. If the problem moves, the sensor is
faulty. Otherwise the harness or module is faulty.
5. Check module harness for pinched, worn, or broken elements. Check
sensor for pinched, worn, or broken wires.
6. Assure hopper is only connected to “ROW 16/HOPPER” connector
input.
HOPPERS FAIL THAT ARE FILLED ABOVE THE
SENSOR. SELF-TEST INDICATED THE SENSOR
WAS PRESENT.
Probable Cause
1. Defective sensor or harness wire that is intermittent
2. Defective harness or sensor cable (signal shorted to ground)
Corrective Action
1. Check module harness connections at the module and sensors. Check
module harness for pinched, worn, or broken elements. Check sensor
cables for pinched, worn, or broken elements.
2. Swap the sensor connection with another hopper connector or move
sensor. If the problem moves, the sensor is faulty. Otherwise, the
harness or module is faulty. Check module harness for pinched, worn,
or broken elements. Check sensor for pinched, worn, or broken wires.
