Moisture reading errors
(reading high or low)
1. Wire disconnected or bad connection
between star wheels and IPM. 1. Reconnect wire.
2. Low power supply to IPM 2. Check voltage at box for min of 12V
3. Baleage not forming full top of bale
allowing star wheels to not properly
contact bale.
3. Adjust flake to contact star wheel
sensors.
4. Short in star wheel harness. 4. Replace wire.

Moisture reading erratic

1. Check all wiring connections for
corrosion or poor contact.
1. Apply dielectric grease to all
connections.
2. Check power supply at tractor. Voltage
should be 12V-14V
2. Replace battery harness. **Install voltage surge protection on
tractors alternator.

Product is less than actual product used.

1. Voltage supplied to flow meter is less
than 11 volts.
1. Check for a min of 11 volts supplied
at IPM module.
2. Wiring short in signal to IPM. 2. Inspect wire and replace if necessary.
3. Using product other than Harvest Tec 3. Catch and weigh product for output.

Product shown is 10% different
than actual product used.

1. High voltage supplied to the meter. 1. Check voltage at IPM. Max of 18V.
2. Air leak in intake.
2. Look for air bubbles in line.Replace line or other defective area that
is allowing air into the system. 3. Using product other than Harvest Tec 3. Catch and weigh product for output.

System leaks product out of
tips after shutting down.

1. Dirty or defective solenoid 1. Clean or Replace.
System does not pause at the end of a row.
1. Short in harness
2. Damaged sensor
3. Sensor misalignment
1. Replace harness
2. Replace sensor
3. Align sensors – see 474C manual

2. Damaged wire from control
3. Wire disconnected
1. Clean or Replace
2. Repair
3. Reattach

ISO Communication Module
light will not illuminate

1. ICM Module receiver not connected
2. Harness disconnected
3. Low power
1. Check connections and voltage.
Minimum of 12.5 volts required.
Green Light – When the ISO Communication Module is properly connected, the
green light will indicate connection.



Baling Rate shows “ERROR"

- The star wheel with the encoder is installed incorrectly
so it is spinning the wrong direction. Ensure star wheel
is installed according to arrow diagram on the back.
“Auto Mode Disabled”
- Microwave chute moisture sensors have been
selected. Ensure they are off and star wheels are used
as main moisture reading for the system.
