Operation
Setting limit
The CMV view in display will give the operator all
information needed during compaction; engine rpm,
gear position, speed, frequency and inclinations are in
display together with actual CMV and the limit set in
brackets. Use the buttons underneath the display to
set the limit. The scale will switch automatically
between 0-75 and 0-250 depending on the CMV
reading.
If double-jump occurs the operator will first get a
warning (!).
Secondly the ABC will shut off vibrations and give a
message to the operator to continue compaction with
a lower vibration amplitude setting or if variable
frequency is available reduce the vibration frequency.
The sensor is fitted on the mounting plate of the main
bearing and it senses the vibrating motion of the drum.
The information is transmitted to the processor unit
where it is analyzed.
The analyzed information is presented in the display
as a digital value expressed in CMV (Compaction
Meter Value). High or low measuring range is
automatically selected and viewed in the display. The
resulting numerical value is a relative measure of the
ground stiffness achieved.
