2-17. Warning Zone

F3SG-RA Series
F3SG-RE Series
2-17-1. Overview
Part of the detection zone can be set as a warning zone.
Example:
• When a person enters, indicator or buzzer should notify warning without stopping a machine.
The Warning Zone is not available for the F3SG-RE.
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-R cannot be excluded, the height of the detection zone and the safety dis-
tance shall be determined in consideration of such a risk.
A warning zone must be configured based on a safety distance.
