[. . . ] Procedure: ­ Position the PR 25 / PR 26 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 5­50 m). ­ Position the PRA 25 / PRA 26 laser receiver at the desired point. ­ Check that no obstacles prevent communication between the PR 25 / PR 26 and the PRA 25 / PRA 26. ­ Activate the auto alignment function by pressing the X or Y key three times within one second. 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 / PRA 26. ­ As long as the PR 25 / PR 26 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. 6. 2. 1 Surveillance The surveillance function checks to ensure that no displacement of the aligned plane has occurred (e. g. If displacement has occurred, the laser plane is realigned to the zero point (as long as it is still within the receiving area). An additional laser receiver is required for working with the surveillance function. As surveillance begins by way of the auto alignment function, the PR 25 / PR 26 must be set up accurately. The PR 25 / PR 26 must be set up so that the correct axis (X or Y) is positioned in the direction in which alignment is to be performed. Procedure: ­ Position the PR 25 / PR 26 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 5­50 m). ­ Position the PRA 25 / PRA 26 laser receiver at the desired point. ­ Check that no obstacles prevent communication between the PR 25 / PR 26 and the PRA 25 / PRA 26. ­ Activation of this function requires the PRA 25 / PRA 26 to be switched off. While pressing and holding the X or Y key (the key for the axis you wish to align), switch on the laser receiver by pressing the on/off key. The surveillance function is indicated in the display ­ the axis currently being aligned and the arrows blink alternately. ­ The auto alignment process stops as soon as the zero point has been found. In contrast to full auto alignment, no audible signal is emitted at the end of the process. ­ A check is carried out at regular intervals to ensure that laser plane has not been displaced. If it is found to have been displaced, the laser plane is again brought 13 en into alignment with the zero point (as long as the laser beam is still within the detector target area and line of sight between the rotating laser and the laser receiver has not been interrupted for a long period).
