NOTE
Inclination can be set and displayed on the PRA 30 in percent (%) or in degrees (°). For instructions on how to set the
desired unit, please refer to section 7.3.7 "Menu options".
1.
Set up the tool in a suitable position for the application, e.g. on a tripod.
2.
Position the rotating laser either at the upper edge or lower edge of the inclined plane.
3.
Position yourself behind the tool, facing the control panel.
4.
With the aid of the target notch on the head of the tool, bring the tool roughly into alignment with the inclined
en
plane (parallel to the plane). For more precise adjustment, first set the inclination and then carry out electronic
inclination alignment (see 7.7.4).
5.
Switch the tool on and then press the "Inclined plane mode" button. The "Inclined plane mode" LED then lights.
The laser beam switches on as soon as the tool has leveled itself. The PR 30-HVS can be inclined as soon as
"inclined plane mode" appears in the display on the PRA 30.
7.7.2 Setting the slope manually 6 14
NOTE
If the tool measures a change in temperature of more than 10 degrees, laser rotation stops for about 40 seconds.
During this time the tool corrects all errors that may have been caused by the temperature change. After this automatic
correction the tool resets the laser plane to the previous inclination and the laser again begins to rotate.
Depending on by how much the rotating laser is already inclined, inclination values of up to 21.3 % can be entered.
The display on the laser receiver shows the angle of inclination.
7.7.2.1 Positive inclinations
The positive inclination entry button ("Plus" button) raises the laser plane ahead of the rotating laser and lowers it
behind the rotating laser.
1.
Press the positive inclination entry button ("Plus" button) on the remote control.
NOTE If no button is pressed for three seconds, the tool will be set to the most recently displayed inclination
value. The inclined plane mode LED then blinks.
The display on the laser receiver shows the angle of inclination.
2.
If you wish to change the value quickly, press and hold the inclination entry button until the desired value is
reached.
7.7.2.2 Negative inclinations
The negative inclination entry button ("Minus" button) lowers the laser plane ahead of the rotating laser and raises it
behind the rotating laser.
1.
Press the negative inclination entry button ("Minus" button) on the remote control.
NOTE If no button is pressed for three seconds, the tool will be set to the most recently displayed inclination
value. The inclined plane mode LED then blinks.
The display on the laser receiver shows the angle of inclination.
2.
If you wish to change the value quickly, press and hold the inclination entry button until the desired value is
reached.
7.7.3 Setting the inclination (slope) automatically 6 15
With this function you can create an inclined laser plane between 2 points automatically and determine the angle of
inclination between these points.
1.
Set up the rotating laser at the top edge of the inclined plane like as described in 7.7.1.
2.
Mount the laser receiver with the PRA 80/PRA 83 receiver holder, for example, on the PUA 50 telescopic staff.
3.
Position the receiver immediately in front of the rotating laser, bring it into alignment with the laser plane at the
correct height, and then secure it on the telescopic staff.
4.
Position the receiver on the telescopic staff at the lower edge of the inclined plane and double-click the "Automatic
alignment" button. Double-click the button again to complete the procedure.
The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place. The
direction of the search can be changed by pressing the "Automatic alignment" button.
As soon as the laser beam strikes the detection area of the laser receiver, the beam moves to the position of the
marking notch (reference plane). Once the position is reached (i.e. the marking notch is found), a signal tone with
a duration of 5 seconds indicates that the process is complete.
The "Automatic alignment" symbol is no longer shown in the display on the laser receiver and the receiver
switches automatically to normal operating mode.
The inclination is shown in the display of the laser receiver for 5 seconds.
