TROUBLESHOOTING
Failures and malfunctions are identified by specific messages of the failure memory and the Diagnose Log. The table below contains
the messages that are visualised, the possible causes of the failure or malfunction that occurred, actions to take to find the problem
and resolve it.

FINDING AND RESOLVING THE PROBLEM
ANOM. +PS
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +PS
The input voltage to the
+PS terminal (control
panel power supply) of the
control panel is
malfunctioning.
Power supply voltage is
< 13.5 V or > 15 V.
Check the power supply voltage, both empty (disconnected from
the control panel) and when charging (connected to the control
panel): it must be between 14.25 V and 14.55 V. In case of a 4 A
power supply, this voltage can be regulated with a trimmer.
If the voltage should drop when the power supply is connected to
the control panel, check that there is not an overload disconnecting
one branch of the power supply at a time.
If the voltage increases when the power supply is connected to the
control panel, check if an incorrect power supply from a self-
powered device is arriving at the +SR terminal.
ANOM. +SR
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +SR
The output voltage on the
+SR terminal (power
supply for the self-
powered devices) of the
control panel is incorrect
(< 11.4 V or > 14.9 V).
If the voltage measured on the +SR terminal is low or absent, check
if there is an overload or a short circuit.
If the voltage measured on the +SR terminal is high, check that if it
is coming from a self-powered device (such devices must have a
diode to prevent this from happening).
ANOM. +V1
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +V1
The output voltage on the
+V1 terminal (power
supply for output
actuators) of the control
panel is incorrect
(< 12.9 V or > 14.2 V).
If the voltage measured on the +V1 terminal is low or absent, check
if there is an overload or a short circuit.
If the voltage measured on the +V1 terminal is high, check if there
is an incorrect power supply from the system.
Note:
in this case, there is also a signal for the +V2.
ANOM. +V2
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +V2
The output voltage on the
+V2 terminal (power
supply for the detectors on
the inputs) of the control
panel is incorrect
(< 12.9 V or > 14.2 V).
If the voltage measured on the +V2 terminal is low or absent, check
if there is an overload or a short circuit.
If the voltage measured on the +V2 terminal is high, check if there
is an incorrect power supply from the system.
Note:
in this case, there is also a signal for the +V1.
ANOM. +D
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +D
The output voltage on the
+D terminal (polarisation
of the data bus) of the
control panel is incorrect
(< 13 V or > 15 V).
If the voltage measured on the +D terminal is low or absent, check
if there is an overload or a short circuit.
If the voltage measured on the +D terminal is high, check if there is
an incorrect power supply from the system.
ANOM. +VBUS
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
ANOM. +VBUS
The output voltage on the
+ terminal (+ power supply
of the data bus) of the
control panel is incorrect
(< 12.9 V or > 14.2 V).
If the voltage measured on the
+
terminal is low or absent, check if
there is an overload or a short circuit.
If the voltage measured on the
+
terminal is high, check if there is
an incorrect power supply from the system.
ANOM. +V2
KPnn.KP xx
FAILURE STARTS
KPnn.KP xx
ANOM. +V2
The output vV
(power supply for the
detectors on the inputs)
from the device is
incorrect (< 7 V or
> 14.3 V).
If the voltage measured on the +V terminal of the device is low or
absent, check if there is an overload or short circuit.
If the voltage measured on the +V terminal of the device is high,
check if there is an incorrect power supply from the system (also
check the voltage supplied on the + terminal, which must not be
> 14.3 V).

PSTN FAILURE
CONTROL PANEL
FAILURE STARTS
UC00.CONTROL PANEL
PSTN FAILURE
Failure on the PSTN
telephone line: the call
tone was not detected for
3 consecutive line tests,
during the automatic line
control or when trying to
send a message.
Note:
The line test,
if enabled, is
carried
out
every
15
minutes.
The ATS4 test,
if enabled,
is carried out continually.
Check if the PSTN line was mistakenly enabled when not in use.
Check the connection of the telephone line on the "LINE" input
terminals.
Check the efficiency of the telephone line.
Check if there is a telephone device connected upstream, between
the control panel and the telephone line (in case of connection of a
PABX switchboard, exclude the line test).
