Table K — Inverter Alarm Codes
Alarm Type Description Cause Solution
Error Not Recoverable
0 NO ERROR No error present on the
system
N/A N/A
1 FAN FAILURE Failed fan or speed
inappropriate
Dust on FAN or FAN failure Replace fan or clean it
2 TEMP TOO LOW Measured temperature
inside the module is below
-20°C
The temperature sensor Replace the module. Wait for
temperature to increase
3 FLASH FAILURE Internal software is
corrupted
Replace the module
4 Vref FAILURE Internal voltage reference is
out of range
Replace the module
5 ALIM AUX1 FAIL Internal 15V supply is out of
range
Replace the module
6 ALIM AUX2 FAIL Internal -15V supply is out
of range
Replace the module
7 TOO MANY
STARTS
Too many starts in 1 minute
( 10 times in 1 minute)
This problem usually
happens when the input
source is not powerful
enough to supply the load.
The inverter has a correct
DC voltage and starts. After it
has started, the power taken
on the input source is too
important and the DC voltage
falls under the minimum and
the inverter stops. After 10
attempts to start, the inverter
stops. The aim of this error is
to avoid a situation in which
the inverter keeps starting
and stopping.
Correct the problem : increase
the input power, reduce the
load, increase the voltage
hysteresis… Then, turn the
module OFF to clear the error
and back ON (or, if you have
no access to the supervision,
unplug and replug the module)
8 OVERCURRENT
OUT
The AC output current has
been too high for too long
Problem with IGBTs or
current sensor or output
stage. This can also
happen in very harsh surge
conditions.
Reset the module and try
again. If the problem persists,
replace the module
9 Vint TOO LOW Intermediate voltage has
been too low
Many causes Reset the module and try
again. If the problem persists,
replace the module.
10 Vint TOO HIGH Intermediate voltage has
been too high
The most likely cause is that
energy has been reinjected
into the module (by the load,
if the Acout has been short-
circuited with the grid)
Check if there is a problem
around the module which
could explain the error. Then,
reset the module and try
again. If the problem persists,
replace the module.
11 Vout PI2 ERROR Error in the self-test during
the starting process
This can be caused by a
problem on the IGBTs
Reset the module and try
again. If the problem persists,
replace the module..
12 Vout MPI2
ERROR
Error in the self-test during
the starting process
This can be caused by a
problem on the IGBTs
Reset the module and try
again. If the problem persists,
replace the module.
