FF-SE Series
Tolerance and detection distances
Installation distance
S ≥ V (t1 + t2) + (L - 0.4 H) + E
Where:
• S: Distance (mm / in)
• t1: Response time of the FF-SE (See technical
specifications)
• t2: Stopping time of the machine (s); i.e. the time interval
necessary to stop the machine, after the protection
device has emitted the stop signal
• L: 1200 mm / 47.28 in
• H: Height of the beam from the ground,
300

• V: Penetration velocity (mm / s or in / s)
( V = 1600 mm / s in Europe) V = 63 in / s in USA
• E: Maximum Error in measurement (see technical
specifications)

SHIELD PE Protection earth
The protection zone is made up of 600 beams. Each beam re-
ceives a signal corresponding to a distance measured using the
light time of flight principle, whatever the reflectivity of the tar-
get. If this signal goes below a user defined threshold during
the surveillance, it means that an object is present in the protec-
tion area. Consequently, the corresponding relay is opened.
The surveillance area includes an alarm zone and a safety zone,
that are user-defined. Both may have an irregular shape which
corresponds to the environment.
Applications: a greater flexibility
The FF-SE being an optoelectronic detecting device, it has a no
touch detection and therefore brings more flexibility on site. Its
principle of diffuse reflection simplifies the installation, com-
pared to the traditional emitter/receiver pair of light curtains.
The protection zones do not need any additional fixture (wall,
fence, door...) since the FF-SE covers a 300° angle and adapts
to existing obstacles. Installation costs are reduced to a mini-
mum and the working position is easily accessible since the
protection is a no-touch type.
In case of a change in the machine or production floor layout,
the FF-SE can adapt very quickly by a re-configuration. The
FF-SE is not linked to any particular set up or machine: it is
exchangeable just by programming.
Compared to a usual safety device (light curtain, safety mat,
door...), the FF-SE includes two protection zones which is a
great asset: the alarm zone, used as an early warning zone,
allows a signal to an intruder that he is close to a dangerous
zone and that his movement is about to stop the machine.
There is still time for the individual to change direction and
avoid a stoppage of the equipment that can be costly if it
occurs often. By avoiding unnecessary stoppage, the FF-SE
increases the production lines productivity without decreasing
the safety: it protects just what is needed.
