Valtra F320: Shuttle Speed Sensor Frequency Discrepancy

The system detects a frequency difference greater than 30% between the two shuttle speed sensors, A1A1/5, 7. This indicates an inconsistency in the signals provided by the sensors.

1. 1

   The sensors B12 and B13

2. 2

   The wiring and connections to the sensors

3. 3

   The signal processing unit for the sensors

1. 1

   Inspect

   Check the physical condition and mounting of the sensors B12 and B13 for damage or misalignment.

2. 2

   Test

   Measure the output frequency of the sensors B12 and B13 while the machine is in operation to confirm the discrepancy.

3. 3

   Verify

   Check the wiring and connections between the sensors and the controller for any faults or poor contact.
