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 discon-
nected.
This can be due to an incorrect adjustment of the C/K parameter.
In order to avoid possible false actions, this alarm has a predefined delay of 90 sec-
onds.
E03
Undercompensation . The unit measures inductive power but all the stages are dis-
connected.
This can be due to an incorrect adjustment of the C/K parameter.
In order to avoid possible false actions, this alarm has a predefined delay of 90 sec-
onds.
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 predefined delay of 5 seconds.
E05
Overvoltage
. The voltage measured in some of the phases exceeds the configured
voltage (Vp-n).
The unit disconnects the capacitors automatically.
In order to avoid possible false actions, this alarm has a predefined delay of 5 seconds.
E06
Low voltage
. The voltage in some of the phases is lower than the configured voltage
(Vp-n).
The unit disconnects the capacitors automatically.
In order to avoid possible false actions, this alarm has a predefined delay of 5 seconds.
E07
Cos
φ
high or low alarm� The three-phase cos
φ
is outside the limits specified in one
of the Cos
φ
alarms (high or low). Also, the measured currents should be higher than
the configured threshold.
In order to avoid possible false actions, this alarm has a predefined delay of 15 seconds.
E08
(7)
Voltage THD Alarm . The Voltage THD levels in some of the phases are higher than
those configured in the Voltage THD alarm.
