9-2 General Considerations
9-2-1 Additional Guarding
Areas of access to the point of hazardous operation not guarded by the F3SL system must be protected by suit-
able means such as a fixed barrier guard, an interlocked guard or a safety mat. See Figure 9-6.
Figure 9-6 Correct Light Curtain Installation Example
9-2-2 Installation of Multiple Systems
When two or more F3SL systems are mounted in close proximity and in alignment with each other, precautions
should be taken to avoid one curtain interfering with another. This can be corrected by mounting the emitters
and receivers back-to-back or stacked. See Figure 9-7 for reference.
