PC and the relative software (order code A25060000000045), used for the quick parame-
ter set-up.
The following table indicates the alarm codes and the relative meaning of each along with
the default setting.

Note:
None of the above-indicated alarms are non-volatile.
In MANU mode the steps disconnection takes place only for the No voltage release
(micro-breaking) alarm A09 - No-voltage release.
A01 - Under compensation
Capacitors are all connected and cosf is lower than the set-point value.
A02 - Over compensation
All capacitors are disconnected and cosf is higher than the set-point value.
A03 - Low current
Current value is lower than 2.5% full scale value. In automatic, the capacitors are discon-
nected after 2 minutes of the alarm activation.
A04 - High current
Current value is 120% higher than full scale value.
A05 -Low voltage
Voltage value is -15% lower than lower rated voltage.
A06 - High voltage
Voltage value is +10% higher than higher rated voltage.
A07 - Capacitor overload
Current value flowing in the capacitors is higher than the set threshold (refer to P.20 and
P.21 of advanced menu).
