– Important Installation Considerations
1. Consider reflective
surfaces that may
give rise to an optical
‘short circuit’ from the
direct path of the
safety
light curtain’s
infrared beams as
shown in the first
illustration of Fig. E.
To ensure the safety
light curtain is
mounted far enough
away from reflective
surfaces use the
formula provided to
calculate the
minimum distance
(X) between the light
curtain and reflective
surface.
2. To prevent
intermittent tripping of
the safety light
curtain ensure that
extraneous infrared
energy between 800
and 1000
nanometres is not
directed towards the
Perspex window of
the receiver unit
(RX). Extraneous
sources would
include infrared
sensors, infrared remote controls, scanning systems or sunlight.
3. Ensure the mounting position of the safety light curtain in respect to the
nearest danger point meets the requirements of European Standard ISO
13855. The Separation distance of the safety light curtain from the danger
point of the machine must be met at all times for safe operation. In order for
the machine to be guarded by the safety light curtain, the machine must be
capable of stopping at any point in the machine cycle.
To prevent personnel from reaching the danger point of the machine additional
mechanical guarding may be required so that any access has to be through
the sensing field of the safety light curtain. The safety light curtain must be
