TROUBLESHOOTING GUIDE / 21
HOPPERS FAIL TO ALARM WHEN SEED IS NOT
BLOCKING SENSOR. SELF-TEST INDICATED THE
SENSOR WAS PRESENT.
Probable Cause
1. Defective hopper sensor
2. Defective sensor or harness wire that is intermittent
3. Defective harness or sensor cable (signal shorted to power)
4. Hopper sensor is connected to seed input
Corrective Action
1. Clean sensing elements using a dry bottle brush. Some seed
treatments require scrubbing with water and a commercial cleanser.
2. 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.
3. Swap the sensor connection with another hopper connector or move
sensor. If the problem moves, the sensor is faulty. Otherwise the
harness or monitor is faulty. Check module harness for pinched, worn,
or broken elements. Check sensor for pinched, worn, or broken wires.
4. Assure hopper is connected to “ROW 16/HOPPER” connector input.
UNIT POWERS ON, ALL LEDS BLINK ON, AND NO

UNIT DISPLAYS AN “E” FOLLOWED BY A MODULE
NUMBER
Probable Cause
1. 8V short error detected by Module

short of 8V supply to ground. 8V supply is generated by each module
for its sensors.
