4.1 General
4.1.1 Description
With the ACEecon system
1)
it is possible to perform comprehen-
sive compression checks. For this, the soil rigidity is determined.
An integrated sensor measures the reaction of the ground to the
vibrating base plate. An LED display within the operator's range
of vision continually shows the measurement value.
This inspection capability provides the user with several advan-
tages, for example
• Always check whether compression progress is being
made and whether the final density has been reached.
• Flawed areas in the compression can be found and
recompacted.
• Over-compression, and material loosening and destruction
can be prevented.
• Superfluous passes or vibrating on surfaces already com-
pacted are avoided. That means more efficient, sparing
use of the machine.
4.1.2 Function
The ACEecon system consists of a control/display panel, and an
acceleration sensor on the base plate.
The integrated sensor converts acceleration of the base plate to
voltage signals. These are transmitted to the controls. There the
compression parameters are calculated and shown visually on
the control/display panel.
4.1.3 Operation
The ACEecon system is especially suitable for loose ground with
little fine material.
The degree and quality of compression depend on the existing
soil conditions. If, despite an adequate number of passes, the
maximum degree of compression is not shown, check the soil for
its suitability for compression and, if necessary take measures to
improve compression. Due to varying soil rigidity, the maximum
value cannot be achieved in every case.
4.2 Operation
The various operating statuses are shown on the control panel
as follows:
• The system starts automatically when the machine is started.
Next, the system initializes:
• The status LED (8) blinks; the LEDs (0-7) light up in a row
from 0 to 7 and then go back off.
• After successful initialization, the status LED (8) glows. The
system is now ready to operate.
• The relative compression value is shown by the LEDs as fol-
lows. The number of glowing LEDs symbolically represents
the increasing soil compression.

•
If the status LED glows, and the 0 LED blinks, the vibration fre
-
quency is to high or too low. No measurement value can be
calculated.
•
If the 0 LED glows, and the status LED gives off a blink signal,
the measuring system is malfunctioning. In this case, contact
Ammann service.
