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
reaching 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 flashing that the
operating frequency has not been reached yet.
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.
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 comes on prior to operation if soils 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.
