Bring close the "d" bracket to the "b" ensemble completely and tighten the knurled knobs to firmly fix the

system.

Fix the "c" bracket to the "a" ensemble using one of the four knurled knobs, without tightening it completely

in order to allow the mutual adjustment between "c" bracket and the laser pointer itself (Fig. 4).

As shown in the previous figures it's sufficient to place such obtained assembly on the light curtain front

panel to have a first rough positioning. Bring close, then, the "d" bracket to the "b" ensemble tightening

completely the corresponding knurled knobs (Fig. 5).

At this point screw last knob fixing together both the "c" and "d" brackets. Tighten the knob firmly keeping

the laser pointer group close to the front panel of the curtain (Fig. 6).

Laser pointer is positioned inside the detection field of the safety device and thus inhibits the functioning

during the alignment phase. In case of safety devices for access control, this inconvenience can be avoided

by positioning the laser pointer in a zone not affected by optic groups. The device functioning is thus not

inhibited and the alignment results can be observed directly on the receiving unit's signalling LEDs.

ALIGNEMENT

1) Power on the laser pointer rotating pushing the dedicated switch. Orientate the emitting unit in order that

the laser beam hits the receiving unit at the same height of the pointer.

NOTE: The holes of the fixing bracket or the orientable supports or the rotating brackets, available

as accessories, can be used to orientate the unit, allowing angle adjustment along the vertical unit

axis. If necessary the inclination of the floor stand can be changed by simply mounting washers

under the base.

2) Repeat this procedure inserting the pointer in the lower part of the emitting unit; if necessary repeat this

procedure unit the desired result is obtained.

3) Insert the laser pointer in the upper part of the receiving unit and orient this unit in order that the laser

beam hits the emitting unit as indicated.

4) Repeat this procedure inserting the laser pointer in the lower part of the receiving unit.

After this operation, fix the position of the light curtain remove the laser pointer from controlled area and

switch on the safety device and verify the correct alignment.Finally, centre the laser pointer transversal

position keeping it close to the front panel, fix defiantly (Fig.7).

NOTE: The laser pointer, due to mechanical tolerance problems in the matching with the light

curtain housing, provides an approximate indication and hence small corrections may be necessary

in the unit alignment, following the ALIGNMENT PROCEDURE described in the safety light curtain

instructions manual.

FIXING



To disengage the laser pointer is enough to totally unscrew the knobs shown in Fig. 10 and partially the

remaining ones.

After the aforementioned operation firmly fix the TX and RX units.
