Manual Energy Storage Inverter ESI-S
Table 57: Abnormal states of the controller board LEDs (after auxiliary power is applied to the
system)
Symptom
Cause
What to do
The two green main
controller board LEDs are
blinking but the DSP
controller LED (4) is blinking
twice as slow as the
µ
controller LED (1).
The ESI-Manager shows
‘ACK. FAULT’ and gives
error message ‘Bad
parameters’.
The inverter
parameters entered
by the commissioning
engineer are not
consistent with the
inverter configuration
reported by the
controller.
Check the commissioning parameters
and correct where necessary. (Cf.
Chapter 8
).
The red LED (3) on the main
controller board is on.
The inverter is
stopped due to an
unacceptably high
number of critical
errors.
−
Check the inverter event log to
analyze the critical errors. Refer to
to know what to do in
order to solve the problem
reported.
−
After resolving the problem, the
fault has to be acknowledged and
the inverter has to be restarted
manually.
One of the two controller
LEDs (1-4) on the main
controller board is not
blinking while the other one
is.
One of the controllers
is not starting up
properly. Eventually
the red LED (3) will
switch on.
−
Check the inverter event log to
analyze the critical errors. Refer to
to know what to do in
order to solve the problem
reported. Most likely the controller
board has to be replaced.
−
After changing the main controller
board, the inverter has to be
recommissioned.

Contact your ABB service provider. Most
likely the controller software has to be
upgraded or the main controller card
replaced.
