accurately in-line with each other and are both perpendicular and parallel to
each other within the parameters shown for each axis.
5. If utilising mirrors to deflect the light curtain ensure the mirror length is 50mm
longer at either end of the light curtain detection zone width and mounted
centrally to the zone. To ensure reliable operation the light curtain deflection
angle (A) from the mirror must not be less than 40 degrees or greater than 100
degrees. (See Appendix 3)
Environmental factors can affect the operation of a safety light curtain and proper
consideration should be taken into account for mounting a system where fog, rain,
smoke, dust, large temperature fluctuations etc. is a consideration.
Safety light curtains do not protect personnel from chemicals, heat, gases,
radiation, flying parts etc. They are not a physical barrier.
The machine operators must be instructed in the use of the safety light curtain by
the owner/provider of the machinery.
