6.5 Dynapac Compaction Indicator (DCI)
The DCI informs the driver about the compaction status of the road
substructure and enables the detection and selected re-compac-
tion of weak spots.
An acceleration sensor on the base plate measures the reaction of
the subsoil to the base plate of the machine.
The DCI is automatically started by switching the ignition on.
The DCI first of all runs an LED test. The LEDs light up one after
the other, starting with LED (1). Once all LEDs are on, the display
goes out again in single steps.
With the vibration switched on, the measuring value is displayed by
the LED display (1
-
10).
If the display value does not increase any further, no further com-
paction can be achieved with this machine.
The maximum display value (LED display 1
-
10 and
warning display a) is not always reached.
Due to fluctuations in the measuring value, the dis-
play value can vary by one digit up/down during a
pass.
The average display value during the last pass is
decisive.
The warning display (a):
n
Flashes for approx. 1
-
2 seconds after the vibration has been
switched on. The display goes out as soon as the vibration fre-
quency has been reached.
n
Flashes if the vibration frequency is too low.
n
Lights up, when at the same time the LED displays (1
-
10)
have gone out, if no vibration has been detected.
In order to achieve the desired compaction condition of the road
substructure, one must always perform a suitable reference meas-
urement before compaction is started.
The reference measurement is used to determine which display
value of the DCI corresponds with the measuring value for soil stiff-
ness.
