Fixed Blanking
This function is only enabled through the SL-VH1S.
In case of normal operation, the OSSD keeps the ON state while the
SL-V detects no interruption in the detection zone, and the OSSD
goes to the OFF state when the SL-V detects interruption in the detec-
tion zone.
On the other hand, if the fixed blanking is enabled to a certain beam
axis, the OSSD keeps the ON state while the SL-V detects interruption
on that beam axis and no interruption in the detection zone except for
that beam axis. Additionally, the OSSD goes to the OFF state when
the SL-V detects no interruption on that beam axis and interruption in
the detection zone except for that beam axis.
As shown in the right figure, when the fixed blanking function is
applied, a hazardous clearance that is not protected by the SL-V
may be generated between the obstacle and the SL-V. You must
install an additional safety measure such as a safeguard for this
clearance.
The fixed blanking can be configured to any of beam axis, including the beam axis of SL-V in series con-
nection.
