ABK2027IQE01_A - Installation and Operation Manual
Alarm
Name Variable Code LED Lighting Description
Arrestors 3 0x0020 Red
The purpose of the surge arrester protection alarm is to
monitor the status of the unit's AC and SC surge arresters.
The monitoring signal of the AC and SC surge arresters is
serialized.
Ventilation 3
0x0040
0x0080
0x0100
0x0800
Red
Anomaly in the unit fans.
The inverter monitors the status of the fans. If the control
sends a start signal to the fan and it does not turn, the
control performs a series of actions to try to make it
start. If the fan still does not start, the unit generates a
ventilation alarm.
Exchanger
ventilation.
3 0x1000 Red
Anomaly in the cooling system of the power block where
the electronic cards and power phases are installed.
The system monitors the proper operation of the fans and
their activation circuit.
Preload circuit fault 3 0x0200 Red
Some of the preload processes (preload from AC or from
DC) have not completed correctly.
The preload from AC is used to load the DC BUS from the
electric grid. It is useful for connecting the inverter at night
or to systems with batteries.
The DC preload is designed for units with batteries.
Fan card 3 0x0400 Red
Breakage of the fan monitoring card. If the card is
damaged, the ventilation system will not operate correctly.
Electronic supply 3 0x2000 Red Some of the electronic supply signals are not correct.
Config. change 3 0x8000 Red Inverter setting change
Insulation fault 4 0x0001 Orange
The inverter is continuously analyzing the impedance
between the bus positive and ground as well as between
the bus negative and ground. In addition, it analyzes the
possible bus voltage imbalance between the two voltage
measurements between positive and ground and negative
and ground. If the impedance measurement is lower than
that configured, the inverter indicates an insulation fault.
Low DC voltage 4 0x0004 Orange
Insufficient DC voltage to ensure the correct operation of
the inverter. It only occurs if the inverter is connected to
the grid.
If it occurs repeatedly, check the DC voltage using the
unit's internal oscilloscope. If the alarm persists, contact
the Technical Service.
Control Saturation 4 0x0020 Red
The control output signal is close to the maximum values
for extended periods of time. This effect occurs because
the relation between the DC voltage and the AC voltage is
low, one of the plant protection elements has disconnected
and the unit has suffered an AC overvoltage that has
prevented it from controlling the current properly.
Synchronization
system
4 0x0040 Red
Fault in the inverter synchronization system.

connections module” .

Red
When the inverter is not running it evaluates the condition
of the fiber optics that control the power block. Review the
power block in the event that this alarm appears.
Ancillary services
system
4 0x0400 Red
The inverter is continuously monitoring the ancillary
services voltage. If the voltage is not within a specific
threshold (80% Un
Aux
and 120% Un
Aux
).
Check the ancillary supply voltage to the unit.
