5.2.- MEASURED PARAMETERS
When the device is in normal RUN mode, the following parameters can be displayed: cosφ,
mains current, THD of both mains current and mains voltage.
The device can also display the maximum values of mains current and voltage since the last
parameters clear.
The parameter being displayed can be selected with the navigation keys and is indicated by
the
cursor.
5.3.-ERRORSANDERRORMESSAGES
In case that the regulator detects a possible error, the front screen shows an error code. The
possible error codes are listed and explained in
Table 7.

Therelay remains connectedin absence ofalarm (positive safety)and disconnects incase
that one or more of the errors listed in section
“5.3.- ERRORS AND ERROR MESSAGES” occur.
Notice that the absence of supply voltage will always be detected as an alarm condition
The alarm relay has a delay of 10 s in case of Over-compensation and Under-compensation,
buttheoperationisinstantaneous(delay<1s)incaseofOver-voltage and Over-current.
