5.3.4 Machine protection – installation (optional)
The acceleration load of the upper mass is monitored via a machine protection sensor. When a threshold
value corresponding to operation of the vibratory plate on an extremely hard surface (concrete, asphalt)
is exceeded, a warning is given to the operator. This warning is that the control lamp on the center pole
head or the receiving unit will flash red.
In addition, the machine will respond in one of the following ways (adjustable in the machine
configuration):
Only an entry in the error memory.
Lowering the excitation speed.
Shutdown of the machine with entry in the error memory.
Switching to slow mode.
5.3.5 Compatec – compaction display (optional):
Compatec – compaction display is attached to the rear protective hood and is within the operator’s line-
of-sight. The display, which consists of eight light-adjusting LEDs, displays the relative compaction
progress by successively lighting up. When the number of illuminated LEDs no longer increases, this
means that no further compaction can be achieved with the machine. The operator can finish the work
and avoid unnecessary passes or over-compaction of the soil.
The overload display indicates if the machine is being operated on too hard of a surface. The operator
is notified of this through rapid flashing of all eight LED's.
Compatec – compaction display is suitable for all highly compactable and mixed-grained soils.
5.4 Versions
This operator’s manual covers the following models:
NOTE
Compatec – compaction display only supports soil compaction and does not replace the
professional measuring of soil density by an expert.
