System Diagnostics to Detect Operational Abnormalities

Detection of ground trouble and soft ground

1.For a case of unstable ground or soft ground (soil containing high clay content) for which the use of this machine is not suitable, only the green and red LEDs will be on (Figure 27), with no yellow LED's on.

If this occurs it would be challenging to achieve the desired compaction results. Check to make sure the ground conditions are prepared to specification before proceeding with the compaction process.

Detection of Vibration Abnormality

2.When appropriate vibration frequency cannot be achieved during operation due to improper engine RPMs (Figure 28) the green LED will flash. When this occurs check the engine RPMs and the V-belt tension as it could be loose.

3.If red and green LEDs are flashing alternately as shown in Figure 29 then please check the sensor wire because there is a possibility that it is disconnected.
