5.1.5. Multiple light curtain arrangement
When using several optoelectronic safety devices in
the same application, the systems should be in-
stalled in such a way that they cannot interfere with
each other. Care must be taken that each receiver
only receives light from its own emitter (Figure 11).

The safety light curtain has been thoroughly tested
against light interferences according to the stringent
requirements of IEC 61496. Nevertheless any direct
interference into the receiver with other infrared
sources like through beam photoelectric sensors,
laser scanner, transmitters etc. should be avoided.
5.2. Mechanical
installation
Be aware that a rigid, flat base, isolated against
shock and vibration should be selected to mount the
Safe2+ or Safe4. This in combination with the stan-
dard mounting brackets set will keep the initial
alignment during operation even in harsh industrial
environments.
5.2.1. Mounting brackets
The backside of the light curtain profile has continu-
ous grooves to fix the mounting brackets at any posi-
tion along the light curtain housing (Figure 22).
Edges up to a length of 1800mm are fixed using two
brackets. Longer edges with 3 brackets. Each sys-
tem includes necessary clamps (Standard 30mm
Mounting Kit, Part No. 106 500). They are adjustable
within ± 4º for a perfect alignment of the light curtain.
Optional available mounting brackets (Figure 12):
•
Vertical mounting brackets for mounting the
light curtain in the vertical axis of the light cur-
tain. (± 4º adjustable)
•
FGS mounting profiles (not adjustable)
•
180° Mounting, rotation ± 90°, for applications
where the mounting angle is not set using the
mounting frame.
