7.2.3 Working in the horizontal plane
– Mount the tool suitably, depending on the application,
e.g. on a tripod.
– Press the on/off key.
-NOTE-
The laser beam switches on and begins to rotate as soon
as the tool has leveled itself.
7.2.4 Working in the vertical plane
– Stand the tool on a level surface in a suitable position
for the application.*
– Press the on/off button.
-NOTE-
*In order to obtaine the specified accuracy, the tool
should be stood on an approximately level surface.
-NOTE-
The X LED does not light (the X-direction is brought into
vertical alignment automatically and monitored).
The Y LED lights red (the Y-direction can be aligned man-
ually by way of the servo keys, the laser plane remains
perpendicular).
7.2.5 Automatic alignment
A basic prerequisite for auto alignment is that the PR 25
is set up accurately. The PR 25 must be set up so that
the correct axis (X or Y) is positioned in the direction in
which alignment is to be performed. This can only be
done in conjunction with the PRA 25.
Procedure:
– Position the PR 25 at the reference point and with the
correct axis in the direction in which alignment is to
be performed (the operating range for auto alignment
is a radius of 5-50 m).
– Position the PRA 25 laser receiver at the desired point.
– Check that no obstacles prevent communication between
the PR 25 and the PRA 25.
– Activate the auto alignment function by pressing the
X or Y key three times within one second. It is impor-
tant that the axes correspond correctly, i.e. when X (Y)
is to be aligned with the reference point, auto align-
ment of the X (Y) axis must be enabled by way of the
PRA 25.
– As long as the PR 25 is not in line laser mode, it then
switches automatically to medium rotation speed and
begins the search process. The auto align function is
indicated in the display by the axis currently being
aligned and by blinking arrows. An audible signal is
emitted continuously during the search process.
– The direction of the search process can be changed
by pressing the direction arrows.
– The beam moves to the zero point (reference plane)
as soon as the laser beam strikes the detection area
on the PRA 25 laser receiver.
– After reaching this point (finding the reference plane),a
signal sounds briefly indicating that the process is
complete. Only the axis that has been aligned is then
shown in the display.
If the process cannot be completed within a certain period
of time, an error is indicated in the display.
-NOTE- If an error is displayed
Please check that the PRA 25 is positioned within the
inclination range (+/– 5°) and that no obstacles are
located between the rotating laser and the laser receiver.
7.2.6 Manual alignment with the PR 25
A basic prerequisite for manual alignment is that the
PR 25 is set up accurately. The PR 25 must be set up so
that the correct axis (X or Y) is positioned in the direc-
tion in which alignment is to be performed.
Procedure:
– Position the PR 25 at the reference point and with the
correct axis in the direction in which alignment is to
be performed (the operating range for manual align-
ment is a radius of 5–50 m).
Setting the X-direction manually
– Press one of the X-servo keys twice within 2 seconds.
– The X-servo keys can then be used to perform man-
ual alignment.
-NOTE-
The X LED lights red.
Setting the Y-direction manually
– Press one of the Y-servo keys twice within 2 seconds.
– The Y-servo keys can then be used to perform man-
ual alignment.
-NOTE-
The Y LED lights red.
7.2.7 Manual alignment using the PRA 25
A basic prerequisite for manual alignment is that the
PR 25 is set up accurately. The PR 25 must be set up so
that the correct axis (X or Y) is positioned in the direc-
tion in which alignment is to be performed.
Procedure:
– Position the PR 25 at the reference point and with the
correct axis in the direction in which alignment is to
be performed (the operating range for manual align-
ment is a radius of 5–50 m).
– Check that no obstacles prevent communication
between the PR 25 and the PRA 25.
– Activate the manual alignment function by pressing
the X or Y key twice within 1 second. It is important
that the axes correspond correctly, i.e. when X (Y) is
to be aligned with the reference point, auto alignment
of the X (Y) axis must be enabled by way of the
PRA 25.
– The laser beam can be moved to the desired position
by pressing the direction keys. Holding down the direc-
tion keys increases the speed of movement and the
laser line or spot then move continuously.
– The manual alignment function is indicated in the dis-
play by the axis currently being aligned and by sta-
