6.6 Partial Muting
A module is a section of the barrier, the size of which is defined in the tables in 5.7.
The first module is always the one next to the indicator LEDs. E.g. Focus FII-4-30-600 consists of 4
modules, each containing 8 beams, giving a total of 32 beams in the whole barrier.
Switches 4 and 5 has to be set according to the chosen muting function (T, L or X). Switches 1, 2, and 3
in the receiver are set according to the choice of muting all modules, single module or a combination of
several modules. See 4.4. Default setting is for muting of all modules (1, 2, and 3 are in the position "Off").
Muting of a single module makes it possible to disconnect only one module at every muting moment.
Muting of several modules makes it possible to disconnect two or more modules, or even the whole barrier.
NB!
– When muting a single module, the module that contains the synchronising optical beam, which
is located furthest away from the M12 connector, must not be chosen. If it is, the muting func-
tion is disabled.
– If muting is chosen from a module which does not exist (e.g. muting of the 4th module in a barrier
that only has 3 modules, e.g. FII-4-K3-800) the muting function will not be activated, i.e. the barrier
maintains protective function at all times, without muting.
– If, at muting of several modules, a choice of muting modules includes one that does not exist (e.g. mu-
ting of modules 1+2+3+4 in a barrier that only has 3 modules, e.g.
FII-4-K3-800) the barrier will choose muting of all existing modules.
The locations of the modules are shown in this
drawing:
For detailed information about how many beams
are included in one module and which switches to
set see table at 4.4 and 5.7.
