Power limitation
Power limitation because the internal temper-
ature is too high. The temperature is mea-
sured on the control card. This is a protective
function of the device.

Waiting for fault acknowl-
edgement
The DSP is waiting for the configuration data
from the HMI.
Configuration of the
device must be con-
cluded in full.

Fault: Grid relay L1
During the self-test, it is discovered that the
grid-side Lx relay becomes stuck. The self-test
does not check whether the relay switches on.
Grid-side Lx relay defective.

Fault: AFI sensor
The AFI sensor is demagnetised prior to feed-
in. If this is not possible, this error message ap-
pears.

Pre-synchronisation not pos-
sible
Adequate voltage pre-synchronization with
the AC grid not possible. Conditions for dis-
play: DC link middle to PE may exhibit a differ-
ence of no more than +-2 V during pre-syn-
chronisation - the internal voltage could not be
aligned sufficiently with the AC grid voltage.
Disconnect AC and
DC, wait 1 minute
and switch on again.
B
181
Insulation error, centre
Insulation error close to the centre of the PV
string (area co-15% of the half of the
string)
As such, symmetri-
cal fault resistances
are also detected.
These must be recti-
fied in order to op-
erate the system
safely and reliably.
