108 Troubleshooting
1006 External fan
run time
The inverter’s software has calculated that
the cooling fan has reached the end of its life.
The calculation considers the manufacturer’s
estimated lifetime as well as the actual
operational environment of the inverter.
The inverter and cooling fan continue to work
normally.
To minimize output
power losses and
service downtime in
the near future, the
maintenance or
service person should
order the spare part
and replace or prepare
for replacement of the
cooling fan.
1007 Internal fan
run time
The inverter’s software has calculated that
the stirring fan has reached the end of its life.
The calculation considers the manufacturer’s
estimated lifetime as well as the actual
operational environment of the inverter.
The inverter and stirring fan continue to work
normally.
To minimize output
power losses and
service downtime in
the near future, the
maintenance or
service person should
order the spare part
and replace or prepare
for replacement of the
stirring fan.
1008 IGBT
thermistor
The temperature sensor on the inverter’s
power electronics board has failed. The
inverter continues its normal functions based
on the remaining functioning temperature
sensors and SW calculations. However, the
power output is continuously limited and
system’s performance is decreased.
User should check the
serial number of the
inverter and
immediately contact
the system supplier
about the warning.
1009 Ctlbrd
thermistor
The inverter’s temperature sensor at the
control electronics board has failed. The
inverter continues its normal functions based
on the remaining functioning temperature
sensors and SW calculations. However, the
power output might be often or continuously
limited and system’s performance is
decreased.
User should check the
serial number of the
inverter and
immediately contact
the system supplier
about the warning.
1020 Autoreset
active
Autoreset is active and is about to reset the
inverter from an overcurrent trip.
Do nothing. Wait for
reset. The warning will
disappear after the
automatic reset has
completed.
2000 Self test not
completed
Self-test has not completed.
If country code 14 (Italy) has been selected,
the inverter will not connect to the grid until
the self-test is completed.
Run the self test.
Check that the AC grid
is present and is within
the allowed operating
range. Check that the
DC voltage levels are
adequate (over
370 VDC).
