2-17. Reduced Resolution
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.
2-17-1. Overview
The Reduced Resolution function prevents the safety outputs to turn off by an object moving in a
detection zone. With this function, an object with a size of 1 to 3 beams can be ignored by changing a
detection capability size. Unless the number of continuously blocked beams exceeds the setting (1 to 3
beams), the total number of blocked beams has no limit. The response time remains the same even
when the detection capability is changed.
The difference from the Floating Blanking is that the Reduced Resolution keeps the safety outputs ON
even when an object is present discontinuously.
Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.
Example:
• Enter of a person into the detection zone is monitored while enter of a transport dolly is allowed.
Example:
The F3SG-SR does not turn the safety outputs OFF when the number of blocked continuous beams is 3 or more. (Fig. 1)
The F3SG-SR does not turn the safety outputs OFF when the number of blocked continuous beams is 2 or less. (Fig. 2)
The F3SG-SR does not turn the safety outputs OFF when there are some combinations of continuously blocked beams
in a detection zone but the number of the continuously blocked beams of each combination is 2 or less. (Fig. 3)
The F3SG-SR does not go to the LOCKOUT state and does not turn the safety outputs OFF even when an object has
been removed from the detection zone. (Fig. 4)
