Features

The setting console--the first in the industry--allows you an easy and safe setting of various
functions.

Includes two types of blanking functions

Blanking function for changing the detection pattern of the
safety light curtain.
Basic pattern 1: Floating blanking function
This function allows you to disable an unspecified 1, 2, or 3
optical axes. If more than the set optical axes is interrupted,
the output shuts off.
(Example of floating blanking function)

The moving rod that is
installed on the machine,
can move up and down
in the protective field.

Basic pattern 2: Fixed blanking function
Specific optical axes are masked by teaching and disabled.
(Example of fixed blanking function)

Optical axis can be shaded
and disabled when a work
piece is in detection area.

Blanking

Fix Blanking Function

The fix blanking function with F3SN,
the instant the work stand removed,
resets blanking, and the invalid
optical axis returns effectively.
Since it is detectable even if a hand
invaded, it is safe.

However, nullification of
mere optical axis will
remain as it is, even if
the work piece was removed.
Since it is undetectable even
if a hand invaded, it is dangerous.

Other functions to be set with the setting console

● Auxiliary outputs: Outputs such as ON at Dark, ON at Light,
light intensity diagnosis, and lockout can be selected.

● Large indicator lamp outputs: large indicator lamp outputs
can be selected from ON at Dark, ON at Light, light inten­sity diagnosis, and lockout.

● External device monitoring function: Allows you to monitor
the feedback of external devices.

●

Interlock function: Interlocks can be set at power-on and restart.

● Setting copy function: Allows you to copy the settings of one
sensor to another sensor.

● Protect function: Changing of sensor settings can be pro­hibited and restricted.

G-6 Safety Sensors / Components

F3SH-A Multi-beam safety sensor

Recommended dimensions of EN standard for
F3SH-A (4-optical axis multi-beam)
Human body detection achieved

4 optical axes at a 300 mm pitch. Detects break by entire
body.

In EN Standard EN999 (machine safety: positioning of protec­tive devices in relation to the approach speed of human body
parts), the values in the following table are recommended as
the most effective regarding the height from the reference sur­face (floor, etc.) of each optical axis of the 4 optical axis multi­beam sensor.
The optical axis pitch of the F3SH-A matches the recommend­ed pitch, and, thus, in the installation shown in the following di­agram, every type of intrusion is detected, including intrusion
by passing under the lowest optical axis and intrusion by
passing over the highest optical axis.
(Installation example based on EN999 recommended dimen­sions for multi-beam safety sensors)

The top end of
the optical axisPeople cannot get over.

Equipped with LED bar for easy use.

Easy optical axis adjustment using LED displays. En­ables certain installation.

When the optical axis from
an emitter is reflected at
the angle of 90 degrees
with using a mirror, the

can be protected by one set
of sensors. Sensing distance
is lowered 15% per mirror.
