The attainable maximum may vary with the type and composition of the soil.
On sand, the maximum is commonly reached at a low number of lit LEDs.
Following the compaction of a mix of gravel and crushed rock that
is uniformly graded and contains the proper concentration of water,
the indicator is likely to show six to seven lit LEDs.
It is important to closely monitor the indicator during the last pass.
Places where the number of lit LEDs drops sharply are poorly compacted.
In these places, the soil needs to be compacted again or may even have
to be replaced.
Possible indicator states
Function test of the LEDs A function test of the LEDs is performed when the ignition
is turned on, but the engine has not yet been started.
The operational status indicator (1) and the warning light (3)
light up permanently.
The LEDs of the compaction indicator (2) light up in
succession from left to right and go out in reverse order.
After engine start, before reach-
ing the operating frequency
The warning light (3) signals by lighting up permanently
that the compaction indicator is not operational yet.
The LEDs of the compaction indicator (2) are not yet lit.
The operational status indicator (1) signals by ashing that
the operating frequency has not been reached yet.
Reaching the operating
frequency, operation
Upon reaching the operating frequency, the operational
status indicator (1) lights up permanently, indicating that
the machine is ready for operation.
The warning light (3) goes out.
The compaction indicator (2) starts lighting up, indicating
the achieved level of soil compaction.
Illumination of the warning
light
The warning light warns of operation on soils that are too hard.
If all LEDs of the compaction indicator (2) are lit together with
the warning light (3), the soil to be compacted is too hard.
Stop operation immediately to avoid damage to the machine.
