Floating Blanking; 2-15-1.Overview - Omron F3SG-2RE0430P30 User Manual

2-15. 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.
Responsible person must ensure that the system works as you intended after configuring floating
blanking. Failure to do so may result 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, which may cause a person to go undetected, resulting in serious injury

2-15-1. Overview
 Floating Blanking Function
This function allows a specified number of beams in the detection zone of the F3SG-RA to move freely
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.
The Floating Blanking is not available for the F3SG-RE.
 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
Setting of the number of floating beams allows setting of the number of beams that do not turn off the
safety output. Setting of the number of floating beams can be configured by specifying the number of
beams manually or by moving an interrupting object in the detection zone. For details of teach-in
setting, see 3-3-2. Setting Floating Blanking by Teach-in.
 Floating Blanking Monitoring Function
F3SG-RA monitors an interrupting object in a floating blanking zone. (If the object is removed or gets
smaller, human entry may not be detected by F3SG-RA, resulting in serious injury.)
F3SG-RA enters lockout when an interrupting object becomes smaller, or removed. (Factory default setting)
It is possible to configure the blanking monitoring function to be disabled when an interrupting object is
smaller or removed.
