2 Functions
2-1 Foreword
This section describes the functions that are provided by the SL-R12EX. These functions allow you to
configure various settings related to the detection performance of the SL-R11 and SL-C Series devices that
are connected to the SL-R12EX and can be set for individual SL-C Series beam axes. For this reason,
references throughout this text to “detection capability” and “beam axes” should be understood to refer to the
detection capability and beam axes of the SL-C Series.
2-2 Floating blanking function
WARNING
When this function is carried out, the SL-C series cannot keep the original
detection capability. The detection capability of the SL-C**F Series varies among
ø14 mm (0.55"), ø24 mm (0.94"), ø34 mm (1.33"), and ø44 mm (1.73") according
to the exact settings used. The detection capability of the SL-C**H Series varies
among ø25 mm (0.98"), ø45 mm (1.77"), ø65 mm (2.56"), and ø85 mm (3.35")
according to the exact settings used. Therefore you must accurately calculate the
new safety distance and install the SLC Series at the minimum safety distance
separately from the hazardous zone or hazards. When installing the SL-C Series
onto/into a machine, always follow the instructions in the SL-C Series Instruction
Manual. Failure to follow this warning may result in significant harm to machine
operators, including serious injury or death.
Normally, the FSD turns OFF-state when an obstacle blocks even a
single SL-C Series beam axis. When this function is enabled, the FSD
keeps ON-state in the event that only a preset number (between 1 and
3) of beam axes are blocked. Only when the number of beam axes
blocked by the objects exceeds that preset number, the FSD turns
OFF-state.
In order to carry out this function, the SL-C Series need not be a single
transmitter/receiver pair. This function can be set for all beam axes on
all SL-C Series units connected in series. (See the right diagram.)
See “4-2 Floating blanking function” (
➮4-2) for more information about
how to set or configure this function.
This function can be configured in one of three ways, as indicated
below.

2-2-1 Floating blanking for 1 beam axis
The FSD keeps ON-state when only 1 beam axis is blocked, and turns OFF-state when 2 or more beam
axes are blocked. Note that for the SL-C**F Series the detection capability is ø24 mm (0.94"), and for the SL-
C**H Series the detection capability is ø45 mm (1.77").
