Elevation Control Key
The Elevation Control Key displays elevation offsets. The key also
indicates the status of the connected sensor with graphics,
informational messages, and colors. The information displayed will
be different, depending on the control application (Figure 3-80 and
Figure 3-81 on page 3-77).
• Upper number – in mmGPS control, displays the current
elevation offset, and can be changed at any time. If the machine is
incapable of paving to the design elevation, the operator dials an
offset into 3DMC, raising or lowering the design surface for a
more manageable surface.
• Lower number – in mmGPS control, displays the current surface
reading. The number continuously updates according to the
elevation difference between the screed edge and the design
(reference) surface.
• Single number – in 2D control, displays the current elevation
setting, and can be changed at any time.
• Elevation Control Key color – the background color of the
elevation control key indicates sensor status.
– Green: indicates sensor status suitable for paving.
