Reduced Resolution
System Operation and Functions
E
Detection capability gets larger when the reduced resolution function is used. When this
function is used, the safety distance calculation must be based on the increased detection
capability for this function. Otherwise, the machine may not stop before a person reaches
the hazardous part, resulting in serious injury.
If detection capability may get larger and a human body may pass a detection zone to
reach a hazardous source, additional safety protection equipment must be installed such
as a safety fence.
The F3SG-RA must be installed, configured, and incorporated into a machine control
system by a sufficiently trained and qualified person. Unqualified person may not be able
to perform these operations properly, resulting in failure of human body detection and
heavy injury.
 Detection Capability
Detection capability for F3SG-RA differs based on the number of floating beams as shown below.
 F3SG-R LED indicator status
When the Reduced Resolution is being enabled, the Blanking indicator turns on.
Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.
2-16-2. Factory Default Setting
The factory default setting is the Reduced Resolution Disable.
2-16-3. Setting with DIP Switch
The user cannot make any changes to this function by the DIP Switch.
2-16-4. Setting with Configuration Tool
Some settings of functions configurable with the Configuration Tool may increase risks.
Make sure the Responsible Person conduct a thorough risk assessment analysis before
managing and changing the settings. Unintended changes to the settings may cause a
person to go undetected, resulting in serious injury.
