How to isolate a malfunction in the installation by following the schematics:
Diagram nr. 1
The first thing that must be done is to check the voltage levels of the general line at the
1316
module, and to follow the flow chart at
diagram nr. 1-A
(if any of the
voltages was not correct).
If the voltage levels are correct, but there is any malfunction when doing the zone setup, then the flow chart at
diagram nr. 1-B
must be followed, and the malfunction
will be located.
Diagram nr. 2
The example at
diagram nr. 2
explains how to locate a malfunction in the installation by gradually excluding alternative options, what should be usual for electrical installers.
The first step will be to disconnect the wires
9
and
90
at the general line in every floor of the building except for the ground floor (provided that the audio processor is
located at that floor). Then we will go to the control console and press
SETUP
ZONE
, select
001
and then press
ZONE SET
. This way, the system can assign a
zone number to every digital module installed in the ground floor. If the process came out well without any incidence, we would proceed to connect the part of the general
line corresponding to the second floor (
point #2
) and assign a zone number to the digital modules installed on it. We must follow this procedure gradually floor by floor until
we discover which line is generating the malfunction in the digital line.
As soon as we discover in which floor is the part of the line that is generating the malfunction, we will have to disconnect the wires
9
and
90
at all the different
junctions of that floor (
points #5, #6, #7 and #8
in our diagram) except for one (
point #5
in our example), and then to proceed with the zone set-up again. We will
repeat this procedure, connecting more and more junctions of the line until we discover the specific part that is generating the trouble.
NOTE:
Please, remember that it is not necessary to start from
Zone 001
each time that we have to assign a zone number to a new module in the system (provided that
there were already other modules present with their zone number assigned). For instance, if there are 20 assigned zones and we need to add zone number to three new
amplifiers, we would press
SETUP
ZONE
in the control console, select
021
and then press
ZONE SET
and assign their corresponding number to the three new
amplifiers without the need to repeat the se-tup of the currently installed modules.
