Note:
None of the above-indicated alarms are non-volatile.
In MAN 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 cos is lower than the set-point value.
A02 - Over compensation
All capacitors are disconnected and cos 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
disconnected 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).
A08 - Overtemperature
Internal temperature value is higher than the set threshold (refer to P.27 of advanced
menu).
A09 - No-voltage release
Voltage failure duration is more than 8ms.
