Active alarms Parameters
Active alarm code E01 to E017
(Table 10)
If there are more than 4 alarms, the information
is scrolled on the screen.
Table 10: Alarm codes.
Code Description
E01
No current. The load current is lower than the minimum value or some of the current trans-
formers (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 device disconnects the capacitors automatically.
E02
Overcompensation. The device measures capacitive power but all the stages are disconnect-
ed.
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 seconds.
E03
Undercompensation. The device measures inductive power but all the stages are 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 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 predefined delay of 5 seconds.
E05
Overvoltage. The voltage measured in some of the phases exceeds the configured voltage
(Vp-n).
The device 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 device 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*
Voltage THD Alarm. The Voltage THD levels in some of the phases are higher than those con-
figured in the Voltage THD alarm.
E09*
Current x I THD Alarm. The IxITHD levels in some of the phases are higher than those config-
ured in the IxITHD alarm. (IxITHD refers to the multiplication of the current by the ITHD of the
same current, see “5.26.- CURRENT x I THD ALARM”)
E10*
Temperature Alarm. The measured temperature is higher than that configured in the Temper-
ature alarm.
E11 No Connection Status due to E08, E09 or E10.
