7.1 Types of
alarms
The controller manages three types of alarms, depending on the reset mode:
l
A - automatic: the alarm is reset and the device restarts automatically when the alarm condition is no
longer present;
l
R - semi-automatic: if the alarm occurs several times, reset becomes manual and an operator needs to
physically restart the device.
l
M - manual: an operator an operator needs to physically restart the device.
Alarms that require technical service are shown on the display with the flashing spanner icon.
If the spanner icon is on, it means that a device has reached the programmed operating hour threshold,
and maintenance is required (the alarm code indicates which device is affected).
7.1.1 Active alarms
Note: the user terminal can only access the active alarms without password protection, or, with
password protection, to the alarms relating to unit initialisation and optimisation.
Active alarms are signalled by buzzer and the Alarm button lighting up. Pressing Alarm mutes the buzzer
and displays the alarm code (on the top row) and any additional information (on the bottom row). Alarm
activation is recorded in the alarm log.
If the alarm is reset automatically, the Alarm button goes off, the alarm code is cleared from the list and
the alarm reset event is recorded in the alarm log.
Procedure (alarm acknowledgement):
1. press Alarm: the buzzer is muted, the alarm code is shown on the display;
2. press UP/DOWN to scroll through the list of alarms;
3. when finished, press Esc and then PRG to exit.
Procedure:
When an alarm is active,
the buzzer sounds and the
Alarm button lights up
Pressing Alarm mutes the
buzzer and displays the
alarm
code; pressing
UP/DOWN scrolls the list of
any other alarms.
When reaching the end of
the alarm list, "ESC" is
shown: press PRG to exit
the alarm list.
Pressing the Alarm button
for more than 3 s resets the
alarms: noAL indicates that
there are no more active
alarms. Press PRG to exit the
alarm list.
A single alarm can be reset by pressing Alarm for more than 3 s. If the condition that generated the alarm
is still present, the alarm will be reactivated. The alarm log can be deleted using parameter ClrH,
accessible via the Service level on the terminal or APPLICA via smartphone, with BLE connection, using
the specific function on the alarm page ("Service" level access). The same operations can be performed
with APPLICA via smartphone, using the specific function on the alarm page (a BLE connection and
"Service" level access are required).
Note:
l
deletion of the alarm log is irreversible;
l
See chapter “Functions” for the alarm parameters: evaporator outlet temperature, frost protection,
compressor.
