[4] Impact and Crushing in the Opening Area (figure 1, risk B)
□
Observe the safe distance indicated in the figure (at the most protruding part of the door).
or
□
Measure the closing stress (with the proper tool
required by regulation EN 12445) as indicated in
the figure.
Check that the values measured by the
instrument are less than the ones indicated by the
graphic.
Take the measurements at height H = 1000mm
(or at the most protruding part of the door).
N.B.
The measurement must be taken 3 times.
□
If the stresses' values are higher, install a
safety device in accordance with regulation EN
12978 (e.g. safety edge) and take the
measurements again.
[5] Impact in the Closing Area (figure 1, risk C)
□
Install two photo-cells (recommended
height: 500 mm) to detect the presence of
the test parallelepiped (height 700 mm)
positioned as indicated in the figure.
N.B.
The sample for detection is a parallelepiped
(700 x 300 x 200mm) having 3 sides with clear
and reflective surfaces and 3 sides with dark and
opaque surfaces.
[6] Impact in the Opening Area (figure 1, risk
B) and in the Closing Area (figure 1, risk C)
□
To further reduce the chance of impact in
the gate's moving areas (A and C), it is
possible
to
install
two
photo-cells
(recommended height: 500 mm) to detect the
presence of the test parallelepiped (height
700 mm) positioned as indicated in the
figure.
