Safety Precautions
Observe the following precautions when using the F3SS.
Regulations and Standards
The F3SS has not received the type certification provided by Article
44-2 of the Industrial Safety and Health Law of Japan.
Therefore, it cannot be used in Japan as a safety device for pressing
or shearing machines provided by Article 42 of that law.
Safety Distance
The “safety distance” is the minimum distance that must be
maintained between the F3SS and a hazardous part of a machine in
order to stop the machine before someone or something reaches it.
If the safety distance is not specified in an individual machine
standard of the EU Standard, the safety distance is calculated as
provided by European Norm EN999 (Machine Safety: Positioning of
Protective Devices Related to the Worker Approach Speed).
Install the Sensor so that the beams are parallel to the floor and so
that the beams will be interrupted only by an erect person. The safety
distance can be calculated as follows assuming that risk assessment
has shown that an independent Single-beams Safety Sensor can be
used.
The intrusion speed (K) and additional distance (C) depend on the
national standards and individual machine standards. Be sure to refer
to related standards.
<Reference>
Method for calculating safety distance as provided by
European Norm EN999 (for intrusion perpendicular to the
detection zone)
Substitute K = 1,600 mm/s and C = 1,200 mm in equation (1)
and calculate as shown below.
Where: S = Safety distance (mm)
Example:
*1. The machine response time is the maximum time from the moment
*2. The F3SS response time is the time required for output to change
Always maintain a safety distance (S) between the F3SS
and a hazardous part of a machine.
Failure to do so causes the machine to fail to stop before
an operator reaches the dangerous area and may result
in serious injury.
Safety distance (S) = Intrusion speed into the detection zone (K)
S = 1,600 mm/s × (Tm + Ts) + 1,200 mm..................................(2)
Tm = 0.1 s, Ts = 0.035 s:
S = 1,600 mm/s × (0.1 s + 0.035 s) + 1,200 mm = 1,416 mm
the machine receives a stop signal to the moment the hazardous
part of the machine stops.
from ON to OFF.
Tm = Machine response time (s) *1
Ts = F3SS response time (s) = 0.035 *2

!WARNING
Recommended Beam Installation Heights
Do not used the product in atmospheres or environments that exceed
product ratings.
Refer to the Instruction Manual for details on installation, connections,
and operating methods.

No. of beams Recommended beam heights from floor (mm)
When using the F3SS as a Single-beam Safety Sensor, we
recommend that the beam height be adjusted to a height of
750 mm from the floor or reference surface to prevent accidents
from occurring as the result of persons crossing over or under the
beam.
The following beam heights from the floor or reference surface are
recommended when using multiple F3SS beams aligned vertically
or using Mirrors to bend a single beams and thus use the F3SS as
a Multi-beam Safety Sensor.
