Setting limit
The compaction meter value 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 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 as CMV, Evib1 or Evib2.
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.
