SE-DM SERIES
Deviating mirrors
NOTES AND WARNINGS
- To guarantee the correct functioning of the safety light curtains, we recommend the use of no more than
three deviating mirrors to deviate the beam along the optic direction.
- Each mirror used decreases the operating range of the safety light curtain by 15%, 20%, 25%. Apply a
correction factor of 85% using one mirror, 65% using two mirrors, 50% for three, of than.
- To maintain the correct functioning of the system, we advise to periodically clean the mirror surface using a
damp non-abrasive cloth. The cleaning frequency depends on the system’s surrounding environment.
- The mirror length has to be at least 100 mm superior to the length of the light curtain’s protected area.
- The mirror has to be mounted in such a manner that its axis (horizontal and vertical) coincide with the
corresponding safety device axis.
- The mirror has to be solidly fixed to avoid accidental movements or strong vibrations.
- The use of the SE-S floor stand is recommended; the mirror is fixed using the two fixing brackets and four
screws provided in the package.
- Given the limited mirror width, the entire system is particularly sensitive also to small rotations along the
vertical axis of the mirror and emitting and receiving units.
Hence particular attention has to be taken during system alignment and part fixing.
- To facilitate system installation (mirror/s and safety light curtain) the use of the Datasensor SE-LP laser
pointer is suggested.
The drawing shows an area protection system composed of a safety light curtain and two mirrors.
INSTALLATION
- Define the area to protect and the precise positions where to install the deviating mirrors and the emitting
and receiving units of the light curtain.
- Fix the floor stands, in the defined points, verifying that their axis are perpendicular to the floor.
- Install the deviating mirrors and emitting and receiving units on the floor stands respecting the warnings
given previously.
- Orient the mirrors to about 45° respect to the optic direction.
- Insert the SE-LP laser pointer in the upper part of the emitting unit; orient the unit in order that the laser
beam hits the surface of the first mirror in an central point of the vertical axis and at the same height at
which the pointer is installed.
- Repeat the same procedure inserting the pointer in the lower part of the unit; if necessary repeat these
procedures until the desired result is achieved.
- Orient the first mirror in order that the laser beam hits the second mirror as described above.
For the angular adjustment rotate the fixing brackets on the re lati ve pins and fi x the screws when the
required position is reached. For adjustments of the vertical axis use the holes present of the mirror’s body
and/or modify the inclination of the floor stand using washers.
- Orient the second mirror according to the same modes used previously guaranteeing that the laser beam
hits the receiving unit.
- Insert the SE-LP laser pointer in the upper part of the receiving unit and, orientating this unit, in order that
the laser beam, reflected from the two mirrors, hits the emitting unit.
Repeat the same procedure inserting the laser pointer in the lower part of the unit.
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 using the normal ALIGNMENT PROCEDURE described in the safety light curtain
instruction manual.
DO NOT move the mirrors as the laser beam guarantees the perfect
alignment.

SE-LP SERIES
Laser pointer
NOTES AND WARNINGS
NOTE: The SE-SP laser pointer uses a red laser light
beam that can be potentially dangerous to the
human eye.
Do not stare directly at the light beam.
The laser pointer is powered by three 1.5 V LR-44 type
batteries.
Battery replacement:
- Unscrew the back lid using the thin pin included in the lid slot.
- Remove the flat batteries.
- Insert the three new batteries placing the negative pole first.
- Screw back the lid.
NOTE: Avoid keeping the device powered a long time.

INSTRUCTIONS FOR USE
•Install the emitting and receiving units of the SE series safety device in the defined positions
(refer to MECHANICAL MOUNTING chapter of the safety light curtain instructions manual). The
use of the SE-S floor stands are recommended, verifying that they are firmly fixed and that their
axis is perpendicular to the floor.
•Insert the SE-LP laser pointer in the upper part of the emitting unit using one of the two side
slots of the profile (refer to drawing).
As shown, the 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.
•Power the laser pointer rotating the front ring nut.
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 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.
•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.
•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.
•Repeat this procedure inserting the laser pointer in the lower part of the receiving unit.
After this operation switch on the safety device and verify the correct alignment.
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.
•Proceed with the definitive mounting of the emitting and receiving units.

SE-S SERIES
Floor stand
The floor stand of the SE-S series can be used for the installation of both the emitter
and receiver units of the SAFEasyTM safety light curtains series, as well as for the SE-
DM deviating mirrors series.
Five versions with different lengths are available in order to satisfy all application needs.
In particular the support post lengths available are given below:
800, 1.000, 1.200, 1.500, 1.800 mm.
Moreover protective stands of the SE-P series are available. These have to be mounted
on the support post using two M6 x 10 screws, and relative washers and square nuts.
The different lengths of the protective stands have been calculated to suit each safety
light curtain model.
ISTRUCTIONS FOR USE
Mount the three angle brackets (A) on the post using the nine M6 x 10 screws (B),
relative washers and square nuts inserting the latter in the side slot of the floor support
post (refer to the figure). Do not tighten the screws in order to allow the angle brackets
to move along the post.
Position the assembled part on the plate (C) and fix the angle brackets using the six M6
x 16 screws (D) and relative washers.
Tighten the fixing screws of the angle brackets to the post.
Before inserting the protection cap (E) on the top part of the post, the square nuts
necessary for the fixing of the emitting and receiving units or deviating mirrors have to
be inserted inside the front slot.
NOTE: For the correct safety device functioning, the floor stand has to be firmly
fixed to the ground using the four inserts given, ensuring that the post is
perpendicular to the ground.
The washers with an one-side opening (given in the package) can be used
to correct the post inclination respect to the ground, inserting them
between the support plate and the ground itself.
