Active alarms Parameters
Active alarm code E01 to E017
(Table 9)
If there are more than 4 alarms, the

Code Description
E01
No current� The load current is lower than the minimum value or some of the
current transformers (CT) are not connected.
It is activated when the secondary current of the transformer is lower than 50 mA
in some of the phases.
The unit disconnects the capacitors automatically.
E02
Overcompensation. The unit measures capacitive power but all the stages
are disconnected.
This can be due to an incorrect adjustment of the C/K parameter.
In order to avoid possible false actions, this alarm has a predened delay of 90
seconds.
E03
Undercompensation. The unit measures inductive power but all the stages are
disconnected.
This can be due to an incorrect adjustment of the C/K parameter.
In order to avoid possible false actions, this alarm has a predened delay of 90
seconds.
E04
Overcurrent. The measured current exceeds the nominal current by +20 %
in some of the phases. The nominal current is considered to be that of the CT
primary.
In order to avoid possible false actions, this alarm has a predened delay of 5
seconds.
E05
Overvoltage. The voltage measured in some of the phases exceeds the con-
gured voltage (Vp-n).
The unit disconnects the capacitors automatically.
In order to avoid possible false actions, this alarm has a predened delay of 5
seconds.
E06
Low voltage. The voltage in some of the phases is lower than the congured
voltage (Vp-n).
The unit disconnects the capacitors automatically.
In order to avoid possible false actions, this alarm has a predened delay of 5
seconds.
E07
Cos φ alarm. The three-phase cos φ is lower than the limit congured in the
Cos φ alarm. Also, the measured currents should be higher than the congured
threshold.
In order to avoid possible false actions, this alarm has a predened delay of 15
seconds.
