DESCRIPTION OF SINGLE MODULE MUTING AND MODULAR
MUTING
With this series of barriers it is possible to specify
single module muting
or
modular muting function
at the moment of purchase
.
There follows a brief description of these two types of
muting.
9.3.1 DEFINITION
OF
MODULE.
Module means a portion of barrier whose size can contain the amount of
optical units per module defined in the table in section 6.
For example, a SBx-600 should be considered as 4 adjacent modules, each
containing 8 optical units for a total of 32 optical units, whereas a SBx-HR-300
should be considered as 7 adjacent modules, each containing 6 optical units
for a total of 42 optical units.
Various configurations can be achieved on request, according to
requirements.
The layout of the modules is illustrated below:

9.3.2
SINGLE MODULE MUTING AND MODULAR MUTING
Single module muting
enables only one module at a time to be made
transparent according to requirements, whereas
modular muting
makes it
possible to make the sum of two or more modules transparent, until even the
whole barrier has been bypassed.
Should a muting request be made for modules that are not managed when in
single module muting
mode (for example bypassing of the 4th module with a
barrier that manages only three), the barrier will remain operational.
Please note that in
single module muting
is not possible to select the
module containing the optic ray placed in the opposite side opf
connector. In that case the muting function will not work properly.
Should a
modular muting
request also involve modules that are not managed
(for example muting of modules 1+2+3 with a barrier that manages only two),
the barrier will enter total
muting
mode
There follow the settings for the various
muting
modes.
