Warning Zone Function
 Overview
Detection zone can be divided into original detection zone and warning zone.
Warning zone output is non-safety output. You must not include it to calculation of safety
distance. Otherwise safety distance may be reduced, resulting in serious injury.
A warning zone CANNOT be used for safety applications. Always install your system so
that a detection zone should be passed before reaching a source of danger.
Warning zone function can be used only when F3SJ is installed horizontally. It CANNOT
be used when F3SJ is installed vertically.
A warning zone must be configured based on a safety distance.
See "Safety Distance: If a person approaches the detection zone of the F3SJ
perpendicularly p.113 " if a detection zone is within vertically installed F3SJ as shown left.
See "Safety Distance: In case of horizontal approach of a human body to F3SJ's
detection zone p.114 " if a detection zone is within horizontally installed F3SJ as shown
right.
 Example
•When a person enters, indicator or buzzer should notify warning without stopping a machine.
