System Operation and Functions

2-18. Warning Zone

When a warning zone is configured, you must attach labels that indicate a border between
normal detection zone and warning zone. Otherwise, the machine may not stop before a person
reaches to the hazardous part, resulting in serious injury.
A warning zone must not be used for safety applications. Always install your system so that a
detection zone should be passed before reaching a hazardous part of the machine. If access to
the hazardous part by reaching over the detection zone of a vertically mounted F3SG-SR cannot
be excluded, the height of the detection zone and the safety distance shall be determined in
consideration of such a risk.
A warning zone must be configured based on a safety distance.
