m/mm = minimum clearance [mm]
Sfb/m = distance from emitter to receiver [m]
5.6 Multiple Systems
NOTE!
• Reciprocal influence of neighboring ESPEs may counteract the system’s safety function.
• Only the light from the associated emitter may strike the receiver.
• Measures for the prevention of mutual influence in multiple systems:
• Non-parallel arrangement (see figure)
(see section “5.5 Clearance from reflective Surfaces” on
• Screening (e.g. by means of partitions)
