Alarms
Next, some of the alarms that are active in the control will be
mentioned.
These alarms will depend on the electrical configuration and the
model of the equipment and depending on these configurations
the alarms shown below may or may not depend on the general
configuration (see next page).
ALARMS
Alarms that require technical assistance intervention indicate
the request on the display by the flashing of the key icon. The
lit key icon indicates that a device has reached the programmed
threshold of the number of operating hours, and a maintenance
intervention is required (the alarm code indicates which device is
concerned).
The reset of some alarms can be configured through a parameter.
The configurable alarms are:
- High pressure switch.
- Low pressure switch.
- Anti-freeze alarm.
PRESENCE OF ALARMS
The display provides access only to the active alarms without
password or, with password, to those dedicated to the initialization
of the unit and its optimization.
The presence of an alarm is signaled by activation of the buzzer
and the flashing alarm icon. Pressing Alarm silences the buzzer
and displays the alarm code (on the top line) and any additional
information (on the bottom line).
The alarm activation is recorded in the alarm log. If the alarm
is automatically reset, the alarm key is turned off, the alarm
code disappears from the list and the alarm termination event is
recorded in the alarm log.
Procedure (alarm acknowledgement):
1. Press Alarm: the buzzer is silenced, the alarm code appears
on the display;
2. Press UP/DOWN to scroll through the alarm list;
3. When the display is finished, select Esc and press PRG to
exit.
In the presence of an alarm, the buzzer is activated and the Alarm
key is illuminated.
Pressing the Alarm key silences the buzzer and displays the
alarm code. Pressing UP/DOWN scrolls through the list of other
possible alarms.
An alarm can be reset by pressing Alarm for more than 3 seconds.
If the condition that generated the alarm still exists, the alarm is
reactivated.
The alarm log can be cancelled by means of the ClrH parameter,
which can be accessed from the Service level from the terminal or
from APPLICA via smartphone, with BLE connection, through the
specific command on the alarms page (it is necessary to access
the “Assistance” level).
The same operations can be performed by acting from APPLICA
via smartphone through the specific commands on the alarms
page (BLE connection is required by accessing the “Assistance”
level).
Pressing the Alarm key for more than 3 s resets the alarms: the
text noAL indicates that there are no more active alarms. Pressing
the PRG key exits the alarm list.
If you reach the end of the alarm list, “ESC” appears: press the
PRG key to exit the alarm list.
