Operating Manual
Safety guidelines
We recommend that you never use more than 3 deviation mirrors
along the light axis to ensure correct functionality.
To maintain correct functionality of the system we recommend
that you regularly clean the surface of the deviating mirror with a
damp soft cloth. Cleaning intervals depend on the environmental
conditions of the system.
The length of the deviating mirror must be at least 100 mm
greater than the length of the protected field of the light curtain.
The deviating mirror must be installed in a way that its axes
(horizontal and vertical) correspond to the respective axes of the
light curtains.
The deviating mirror has to be fixed, so that it cannot be
displaced accidentally or by strong vibrations.
We recommend that you use the PSEN op Protective Column/1
accessories where the deviating mirror can be fixed with the
corresponding assembly kits.
In an environment with strong temperature differences and/or
shocks we recommend to use the PSEN op Mirror Bracket Kit/1.
As the width of the deviating mirror is limited, the reaction of the
entire system is particularly sensitive to turns on the vertical axis
of the deviating mirror and the transmitter and receiver units.
Therefore, particular care is required when aligning the system
and fixing the parts.
We recommend that you use the laser pointer to make the
system installation (deviating mirror and light curtain) easier.
Use of a deviating mirror reduces the effective operating range by
about 15%. This percentage increases further when using two or
three deviating mirrors.

Assembly
Fig. 1 shows a protection system that consists of a light curtain and
two deviating mirrors. The alignment of deviating mirrors is
explained in the following sections based on this example.
Stand-alone installation
Fig. 1
The mounting bracket kit PSEN op Mirror Bracket Kit/1 and a floor
bracket are required for installation.
Define the area to be protected and the exact positions where the
deviating mirrors and the transmitter and receiver units of the light
curtain are to be installed.
Fix the floor bracket to the defined point on the floor and note that
their axes have to be aligned vertically.
Install the deviating mirrors at the floor brackets, and the
transmitter and receiver units, taking into account the notes
above. Insert the screw M6x50 into the slot hole of the rail, then
screw it in with the corresponding washer and nut (Fig. 2) to
install the mounting bracket at the deviating mirrors.
Align the deviating mirror to ca. 45° to the optical path.
Position the laser pointer at the upper part of the transmitter unit
and align the unit so that the laser beam is horizontally in the

middle of the first deviating mirror. The height of the laser pointer
and the height where the pointer hits have to be identical.
Repeat the procedure and align the laser pointer at the bottom
part of the unit. Repeat these steps several times, if necessary.
Align the first deviation mirror so that the laser beam hits the
second deviating mirror in the position described before.
Turn the mounting brackets to set the angle, an when the
required position is reached, tighten the screws. Use the slot
holes at the deviating mirror and/or adapt the inclination of the
floor bracket by adding adjusting washers.
Align the second deviating mirror in the same way and make sure
that the laser hits the receiver unit.
Insert the laser pointer in the upper part of the receiver unit and
align it so that the laser beam reflected by the deviating mirrors
hits the transmitter unit.
Repeat the same process with the laser pointer in the lower part
of the receiver unit.
