System Operation and Functions
2-16. Floating Blanking
Detection capability gets larger when the Floating Blanking 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 to 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.
2-16-1. Overview
Floating Blanking function
This function allows a specified number of beams to move freely in the detection zone of the F3SG-SR
while keeping the safety outputs in the ON state.
Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.
Floating blanking zone
All beams are configured as a floating blanking zone. If the zone overlapped with that of other function
(e.g. Fixed Blanking, Warning Zone), the other function is prioritized in the overlapped zone.
Floating Beam
The number of beams that prevents the safety outputs to be turned OFF can be configured by setting
the number of floating beams. Setting of the number of floating beams can be configured by specifying
the number of beams manually or by moving a blocking object in the detection zone. For details of
teach-in setting, see 3-7-2. Setting Floating Blanking by Teach-in.
Floating Blanking Monitoring function
The F3SG-SR monitors a blocking object in a floating blanking zone. (If the object is removed or gets
smaller, human entry may not be detected by the F3SG-SR, resulting in serious injury.)
The F3SG-SR enters lockout when a blocking object becomes smaller, or removed. (Factory default setting)
In this case, power cycle or reset input enables the Floating Blanking function again with the same
setting as previous one. Turn off the power and on again or turn on the reset input while all the
specified beams are blocked.
It is possible to configure the Floating Blanking Monitoring function to be disabled when a blocking is
smaller or removed.
In case configured as Blanking Disable, if a blocking object gets smaller than the setting value, the
Floating Blanking function is cancelled. That is, the entire detection zone of the F3SG-SR works as the
normal detection zone.
In this case, power cycle enables the Floating Blanking function again with the same setting as
previous one. Turn off the power and on again while all the specified beams are blocked.
If Temporarily Disable Monitoring by Wiring is configured, the monitoring function can be temporarily
disabled during operation by hard wiring of the muting input A and the muting input B. For details, see
below.
If Temporarily Disable Monitoring by Wiring is configured, the Muting function cannot be used.
