5.2 Alarm data logging
Alarms data logging allows storing the air-conditioning unit working state whenever an alarm goes off or
under particular conditions. Any storing operation becomes an event, which can be displayed as any other
event available in
the memory. As it functions as a device for “taking photographs” of the system whenever
any alarm goes off, data logging is extremely useful for suggesting possible causes and solving system
malfunctions and failures. The program is provided with a MAIN and a DEVELOPED data logging.
5.3 Main log
Events can be stored thanks to the boards very large buffer memory. The MAIN data logging can be enabled
by parameter; if the clock card (optional) is not available, neither the MAIN data logging is available. No
additional optional card is required.
The maximum number of storable events is 100; after the last space available in the memory (alarm no. 100)
is used, next alarm will be overwritten on the first alarm stored (001), which will be automatically deleted.
This procedure applies to all following events. The user cannot delete the stored events except at the default
values installation. The MAIN data logging screen can be accessed by pushing button ALARM when screen
E4 is displayed and can be left by pushing button Esc. The screen is displayed as follows:
