GuardShield Micro 400 Safety Light Curtains
Table 21 - Mounting Accessories for Re-inforced Profile
Perimeter Systems (PAC)
Perimeter systems are produced with several single-beam light barriers.
But the flexibility of the GuardShield Micro 400 system also allows the
production of vertical entry safeguarding according to the standard
EN I
SO 13855 [2010]. Such systems are composed of active and passive
elements in one compact profile (see
Table 30
and
Table 31 on page 30
.
The element length of each is 50 mm (1.97 in.).
The significant advantage of GuardShield Micro 400 perimeter systems
is the easier way of mounting and the uncomplicated way of starting up
the operation. The time that is required to connect and align the optics
is reduced in comparison to standard perimeter systems consisting of
single beam light barriers and mirrors.
The protective field and the active elements, respectively, are clearly
recognized as surfaces with the integrated optical lenses. The not
monitored areas (passive elements) are also clearly indicated as black
surfaces.
How to Calculate the Safety Distance S for GuardShield Micro 400
PAC Systems
For vertical mounted perimeter systems or light curtains with horizontal
approach and a resolution larger than >40 mm
(1.57 i
n.), the safety
distance is calculated according to the formula:
S = 1.6 mm (0.06 in.)/ms x T + 850 mm (33.46 in.)
More detailed information regarding safety distance and safety heights
can be found in standard EN 13855 (2010).
