1 Operational status indicator
(Green)
This indicator comes on as soon as the correct operating
frequency has been reached and signals that the compaction
control system is operational.
A flashing of the indicator signifies that the machine is working
with an incorrect operating frequency.
2 Compaction indicator
(Yellow)
The LEDs 1-7 indicate the achieved compaction of the soil.
The number of lit LEDs rises with the increasing compaction.
If no additional LED comes on after another pass over the
same spot, the maximum level of compaction has been
reached.
3 Warning light (Red)
The warning light comes on prior to operation if soils are too
hard.
Such soils cannot be compacted with the machine type used
and may cause damage to the machine.
