10 DIAGNOSTICS
The application is capable of managing a whole series of alarms, relating to compressors, fans, circuits and plant functions. Depending
on the various alarm types, it is possible to configure their resetting (whether manual or automatic), a possible notification delay and
any actions to be taken in that specific case.
When one or more alarms are active, the alarm icon flashes on displays.
In order to view the various alarms, the “Alarm” menu must be displayed from the main page, using the ESC key, followed by the
ENTER key. By pressing the ESC key from an alarm page, or waiting for the 60-second timeout, the user is brought back to the
application’s main page.
To scroll the various active alarms, the ENTER key must be pressed once more: alarms are listed in order of priority, just as they are
listed in the Alarm Table of chapter 6.4.
10.1 Manual and Automatic Alarms
There are two types of alarms: those that are manually reset and those that are automatically reset. These alarms offer the end-user
the choice of selecting, via the associated parameter, the resetting mode that better reflects the user’s own requirements.
10.2 Manual-reset alarms
When a manual-reset alarm is triggered:
• The alarm icon starts flashing.
By pressing the ENTER key from the “Alarm” menu, the code of the first active alarm is displayed.
Once the conditions which had triggered the alarm are back to normal, the alarm can be manually reset. To carry out this operation:
• Go to the page of the alarm to be reset;
• Hold the ENTER key pressed down for about 2 seconds.
At this point, in the absence of any further alarms, the page showing “none” is displayed, the alarm icon is switched OFF, and the
machine goes back to normal operation; otherwise, the code relating to the next active alarm will be displayed.
The consequences deriving from an active manual-reset alarm remain valid as long as the user does not take care of deleting the alarm
message.
10.3 Automatic-reset alarms
When an auto-reset alarm is triggered:
• The alarm icon starts flashing.
By pressing the ENTER key from the “Alarm” menu, the code of the first active alarm is displayed.
Once the conditions that had triggered the alarm are back to normal, resetting and deletion of the alarm message automatically take
place, without any need for user intervention.
The consequences deriving from an active auto-reset alarm remain valid as long as the causes that triggered the alarm are not reset.
