Diagram 1-B
If the voltage levels described
in diagram 1-A are correct, but
the different modules do not
work correctly during the setup
process, we will have to test the
digital line of the system.
We will start a setup procedure
and will look at the condition
of the setup LED indicators of
the different modules, that can
show one of the following
symptoms:
The setup LED indicators do
not blink.
The setup LED indicators
blink very fast.
The setup LED indicators
remain permanently on after
we press the setup button,
but the zone number does not
change in the display of the
control console.
When we remove the 230V~
voltage from the modules
their corresponding zones do
not appear anymore in the
display of the control console.
Centralised installation: Only
those modules directly installed
in the rack
1707
.
De-centralised installation: Only
those modules installed outside
the rack
1707
.
We will check the system by
dividing it into two parts:
See
diagram 2
where it is displayed (as an example)
how to isolate in one installation a problem in the digital
line (wires
9
and
90
).
If the modules work correctly, the origin of the
malfunction is located in the de-centralised part of the
installation.
We will disconnect the general line from the CPU
1316
(15-pin terminal strip) and with the control console
connected we will do a zone setup, verifying the correct
operation of the modules.
If the modules do not work correctly, we will disconnect
the rear flat cable of all the modules, leaving only
interconnected the control console
1202
, the CPU
1316
and the power supply unit
1315
.
We will check the sofware versions in the control console
(by pressing
SETUP
MORE
SOFTWARE
VERSION
). If it does not appear an error in the display
of the control console, the basic modules are OK, and
then we will gradually add the rest of the centralised
modules one by one and will try to assign them a
zone number until we discover which is the one that is
affecting the digital line.
After verifying that the centralised modules work correctly,
we will disconnect the wires
9
and
90
of the different
branch lines of the installation. First we will leave only
one branch line connected. Then we will press
SETUP
ZONES
and assign a zone number to each
device in the line. If this works well, we will continue adding
more and more branch lines until we discover which one
is causing the problems in the line (see
diagram 2
).
