F3SJ-A
User’s Manual
What can be done by the setting tool
Floating Blanking Function
Overview
Turns safety output OFF when F3SJ’s detection capability is enlarged or more than one object is
detected.
When floating blanking is used, detection capability gets larger. To calculate safety distance, you must
use the detection capability under floating blanking.
Otherwise a machine may not be stopped before a human body reaches to the hazardous zone,
resulting in serious injury.
You must ensure that the system works as you intended after configuring floating blanking. Failure to
do so may result in serious injury.
Example
Detection function can be disabled for a moving object with a given width which you do not want to be
detected in the detection zone.
Functional Description
• Floating Blanking Function
Enlarges detection capability to allow an object with a certain size to enter or more than one
interruption at the same time.
• Floating Blanking Zone Setting
In the setting console, all beams are set as a floating blanking zone. With the PC tool for F3SJ it is
possible to set 1 zone, and a zone range can be specified. In the diagram shown below, the 5th beam
is set as the bottom beam and the 10th beam is set as the top beam for a floating blanking zone. Also,
with the interrupting object placed in the appropriate position, it is possible to perform teaching and set
the designated beams manually.
Muting zone and floating zone cannot overlap, thus the zones must be adjusted by the PC tool for F3SJ.
Note that the setting console cannot enable both functions at the same time.
