6.1 Alarms and diagnostics
There are different sources to get information about both the operating state of the convertor
(either in the presence of alarms or not) and the various causes that have brought the system
in alarm/ stop condition.
As already stated in the previous chapter, 4 alarm states of the convertor are available on the
digital outputs of terminal board J1; some information is available using the keyboard while
other information, not necessarily different, can be derived from the 7-segment display on the
front of the convertor.
6.1.1 Visualization and codifying of alarms on the keyboard
Hereafter you will find a table where the different visualizations of memorized alarms are
listed, together with the corresponding number which appears on the 7-segment display.
Moreover, you can see the various messages that appear cyclically when one or more alarms
are memorized (the first line of the alphanumerical display blinks). lf various alarms are
memorized, the message which appears is referred to the alarm with highest priority: it
increases with the increasing of the number, except for I
