10 DIAGNOSTICS
The application can manage a whole series of alarms concerning compressors, fan, circuit, and functions. Based on the different types
of alarms, you can configure their reset (manual or automatic), any delay in warning, and any action to be implemented in that
particular case.
When one or more alarm is active, the alarm icon blinks on the displays.
To view the different alarms, you have to view the “Alarm” menu from the main page, using the ESC key followed by SET. By pressing
the ON/STAND BY key from an alarm page, or waiting for 60 seconds to elapse, the user goes back to the application’s main page.
To scroll through the different alarms active, press the SET key again: the alarms are listed in order of priority, exactly as shown in the
Alarm Table in chapter 10.4
10.1 Manual and Automatic Alarms
There are two types of alarms: manual reset and automatic reset. These alarms offer the end-user the option to choose the means of
reset most suitable to the user’s needs in the associated parameters.
10.2 Manual Reset Alarms
When a manual reset alarm activates:
• The alarm icon starts blinking.
Press the SET key () in the “Alarm” menu; the code of the first active alarm is shown.
When the conditions that set off the alarm return to normal, the alarm can be reset manually. To perform this operation:
• go to the page of the alarm to be reset;
• hold down the SET key for about two seconds.
At this point, if there aren’t any other alarms, the page that says “none” is shown, the alarm icon turns off, and the machine starts
operating normally again; otherwise, the code of the next active alarm is shown.
The consequences that derive from an active manual alarm still stand until the user deletes the alarm message.
10.3 Automatic Reset Alarms
When an automatic reset alarm activates:
• The alarm icon starts blinking.
Press the SET key () in the “Alarm” menu; the code of the first active alarm is shown.
When the conditions that set off the alarm have gone back to normal, reset and deletion of the alarm message occur automatically,
without the user having to do anything
The consequences that derive from an active automatic alarm still stand until the causes that set off the alarm have been resolved.
