Presentation
Use the system to dig with an excavator to a desired depth and
create a leveled plane or to set a slope and create a tilted surface.
Also use it to determine reach, such as for the width of a trench.
All the digging information is referenced to the left, center or right of
the bucket blade (or teeth) and the depth value shown is the
distance from the actual teeth position to the target depth.
Sensors measure the angle of the boom, stick, and bucket. The
information is transmitted instantly to the cab display. LEDs tell you
how far to dig.
A simple one-time procedure allows the EzDig system to “learn” the
dimensions of your machine. That is how it constantly calculates, in
real
time, where the bucket tip is in relation to the target depth.
Excavator rotation and
movement
With EzDig 1D, the operator has to dig “straight ahead” (only
moving the booms/bucket in and out).
After the target depth has been set, the chassis has to stay
stable. Any rotation of it may produce an error depending on the
inclination.
For a leveled plane, rotation of the chassis can be compensated
by using a fourth sensor as a “pitch” sensor on the chassis. This
will automatically correct forward and backward tilting
movements of your machine as well as rotation, providing
accurate depth information.
The optional 2D sensor allows to slew the cab even with a slope
to dig.
The combined Tilt sensor allows to use tiltable tools.
Every time that the excavator tracks are moved, it’s necessary to
zero again the reference (target) depth on a previous point or,
depending on the setup, take the laser height again.

Digging a hole - Method 1: Using the ground as reference
1. Place the tip of the bucket
on your final elevation
(ground) and Short-press
one the elevation symbol:
The screen and the LED
display will indicate the
actual difference of your
bucket tip to the reference
2. Dial-in “0”and confirm
with the checkmark
NB: To redial the previous elevation, you can
user button “fast elevation setting” which redial
the previous elevation:

Digging a trench with 2% slope
Method 1: Using the ground as reference
15

Same as when digging a
horizontal reference, the
screen and the LED display
will indicate the actual
difference of your bucket tip
to the reference.
Digging a trench with 2% slope
Method 1: Using the ground as reference
Short-press the Slope Symbol Dial-in 2.00% and confirm
with the checkmark Place the tip of the bucket on
your final elevation (ground)
then Short-press one the
elevation symbol
Dial-in “0”and confirm with
the checkmark
Note: Without 2D
sensor, you have to dig
straight, not leaving
the slope’s axis by
rotating the cab. A slew
of the cab out of the
axis will instantly lead
to a loss of accuracy!
