8.4.1.6 InPut ERRoR
diagnostics of the local control inputs
From the FAULTS panel (point 8.4.1), press numerical key
5
to access the panel for viewing the diagnostics
of the local control inputs. The diagnostic state of each item monitored is reported, as shown in the following
table. Press ESC to return to the panel FAULTS.
8.4.2
IMP. REAL tIME

Real-time line impedance
Panel for checking the impedance values measured in real time, and percentage variations from the value stored during start-up, using the “Line
impedance acquisition” procedure.
The lines being used are listed. You can select a numerical key to access the corresponding panel indicating
the impedance measured in Ohms referred to the parallel of lines A and B connected to that line.
8.4.1.7 CoMMunICAtIon FAuLt
diagnostics of the internal data communication of VAC 2006
From the FAULTS panel (point 8.4.1), press numerical key
6
and access the panel for viewing the diagnostics
of the internal data communication of VAC 2006. The diagnostic state of each item monitored is reported in
the following table. Press ESC to return to the panel FAULTS.

persists, disconnect the line connecting the
activation contact and connect a 20 k

resistor
between the +24V service terminals and the control
input. If the problem persists, contact Servicing.

If the percentage of variation exceeds the level of tolerance set at the time of configuring the system, a “LOUDSPk LINE FAULT” due to an
excessively high or low impedance (Impedance Hi or Impedance Low) will be signalled.
