ABK2027IQE01_A - Installation and Operation Manual
Alarm
Name Variable Code LED Lighting Description
PWM HW fault 1 0x1000 Red
The voltage variation in the DC bus exceeds a maximum
value. The DC voltage under normal operation remains
constant, with changes due to the control of the maximum
power point. This behavior is generally due to a fault in the
power electronics or a loss of insulation in the DC side.
DC/AC fault 1 0x2000 Red Isolated fault in a power electronics switch.
Inverter lock 1 0x8000 Red
Caused by several different alarms considered critical
enough, which are repeated a specific number of times.
Manual stop 2 0x0001 Orange
It can be caused by the following:
• Emergency stop button pressed.
• Folding doors open (end switches not pressed).
• Stop from display.
• Stop from remote control (via communications
frame).
• Stopped by user by placing a contact in the
emergency push button and end switch
monitoring circuit.
Hardware error 2 0x0002 Red
In the grid connection process abnormal events can
occur, such as overcurrent in the power block output or
overcurrent in the grid filters. This alarm can also appear
if the serial number of the card does not match the unit's
firmware, or due to an overload in the program's memory
system.
Leak current 2 0x0004 Orange
The instantaneous sum of the AC currents exceeds an
instantaneous maximum value.
Monitor the insulation of the AC to ground circuit.
Power consumption 2 0x0008 Orange
Normal photovoltaic unit stoppage when the PV array
power is null.
Temperature 2
0x0040
0x0080

Orange
The inverter control monitors the temperature of critical
elements. In the event of high temperature in said
elements or abnormal temperature differences with the
ambient temperature, the inverter is stopped. A warning
will be generated previously.
Check the condition of the fans, remove foreign bodies
from the ventilation duct, and blow on them to remove dirt.
In addition, check the units' ventilation duct, inlet grilles,
air filters, and outlet grilles.
Fault in IGBT R-S-T 2
0x1000
0x2000
0x4000
Red
The unit's driver stage detected an overcurrent in one of
the power switches.
Phase R
overcurrent
2 0x8000 Red
During a transient the unit has generated a current above
the limit established in phase R.
Phase S overcurrent 3 0x0001 Red
During a transient the unit has generated a current above
the limit established in phase S.
Phase T overcurrent 3 0x0002 Red
During a transient the unit has generated a current above
the limit established in phase T.
AC contactor fault 3 0x0004 Red
Anomaly in the AC contactor actuation system, which
allows the connection of the inverter to the electric grid.
DC contactor fault 3 0x0008 Red
Anomaly in the operation of the contactor or DC motorized
switch.
AC Protection 3 0x0010 Red
One of the AC thermomagnetic circuit breakers has
tripped and remains open. For the correct operation of the
inverter they must be closed.
Check the condition of these protections.
