MOTOR OR ADJUSTMENT SCREW LOCKING:
possible locking of the adjustment screw
in an intermediate position
BLOCKING ALARM
OUT1 NC = Closed
OUT2 = Open
OUT3 = Open
The device remains blocked and sets in its
closing position, performs the zero and full
scale acquisition after the “Reset Alarms”
control
YES
- OPERATING SCREW MECHANICAL BLOCK
- MOTOR PHASE SHIFT
- REGULATOR-ACTUATOR FIXING SCREWS
LOOSENING
- "Reset alarms" control: The device
performs the zero and full scale acquisition
to check that the stroke set is congruent, if it
does not find mechanical blocks it resumes
normal operation; if during the "Alarms reset"
control it does not find the correct stroke,
check manually if it performs a 1.5 turn
rotation
- Check the screws tightening

MAINS VOLTAGE BLACKOUT:
indicates that there was an electric supply
failure for
less than 60 minutes
NON-BLOCKING ALARM:
When the electric supply is
restored it resumes normal
operation
OUT1 NC = Closed
OUT2 = Closed if set
OUT3 = Open
When the electric supply is resumed, the
device restarts the water mixing
YES, at the
return
of the electric
supply mains
- MAINS BLACKOUT
- BOARDS CONNECTOR NOT FIXED
CORRECTLY
- Check mains electric supply
The alarm is not recorded in the alarm log;
after 5 minutes the alarm is
automatically deleted

DISINFECTION FAILED:
indicates a failed disinfection
NON-BLOCKING ALARM
OUT1 NC = Closed
OUT2 = Closed if set
OUT3 = Open
The device returns to the water mixing
status, the first successful disinfection
clears the alarm condition but records it in
the log of the last failed disinfections; the
display shows the symbol "Manual".
YES, it is also
recorded in the
last 10
disinfection
failed
- DISINFECTION NOT PERFORMED
ACCORDING TO THE PARAMETERS SET
- The alarm condition is cleared at the next
successful disinfection or by means of the
"Reset alarms" control. The result of the
disinfection is kept in the log of the last
10 failed disinfections. If the error occurs
frequently, check that the parameters set are
congruent with the system
- Check the recirculation circuit
- Check inlet IN2 contact closing

THERMAL SHOCK FAILED:
indicates a failed thermal shock
NON-BLOCKING ALARM
OUT1 NC = Closed
OUT2 = Closed if set
OUT3 = Open
The device returns to the water mixing
status
YES
- THERMAL SHOCK NOT PERFORMED
ACCORDING TO THE PARAMETERS SET
- The alarm condition is cleared at the next
successful thermal shock or through the
"Reset alarms” control
- Check the parameters
- Check the recirculation circuit

DEVICE MAXIMUM TEMPERATURE
EXCEEDING (90°C):
indicates that the flow probe T1 has read a
temperature value greater than 90°C
SELF-RESETTING BLOCKING
ALARM:
The device resumes its operation
when the probe T1 returns to the
set value
OUT1 NC = Closed
OUT2 = Open
OUT3 = Open
The appliance sets to the closing position
YES
- SYSTEM ANOMALY
- FAULTY FLOW PROBE
- Check the operation of the system or check
the actual value measured by the probe
comparing it with suitable instruments
Alarm management
To make it easier to resolve any functional faults that occur after installation and commissioning, the device is configured so that faults are indicated by
special alarms so as to take the appropriate action.
The cause of the alarm is displayed in the status log.
If the alarm does not inhibit all functions, only the "Maintenance" and "Manual” symbols
will be shown on the display;
the alarm will still be displayed in the appropriate log.
In case of potential hazardous conditions the device sets in a safety condition.
Depending on the type of alarm, certain actions are undertaken, relay statuses modified and information shown on the display and LEDs.
The following table gives a summary of the various operating statuses that follow an alarm.
