8 ALARM MENU
The ALARM menu is used to view (and reset, if necessary) the alarm conditions that
may arise on the unit while it's working. The alarms are divided into various catego-
ries according to their seriousness. Remember that some of them can cause serious
damage to the unit so, before performing a reset, it's important to be sure about the
nature of the alarm and the reason it was triggered (contacting specialised techni-
cal personnel if necessary).
NOTE: The top-left corner of each window shows which compressor is currently
providing the displayed data (U:1,2,3 o 4); to switch between compressors (only
possible from Master unit), refer to that explained in paragraph "3.3Unit operating
status information (real time data)p.7".
